    were used by their clients to conceal income from the
    Internal Revenue Service (IRS) and thereby avoid pay-
    ment of taxes. A grand jury indicted each of the Appel-
    lants with conspiracy to impede the IRS, and also
    returned indictments charging Debra Hills and Brent
    Winters with filing false income tax returns. After a
    joint trial, a jury found Kenton Tylman and Hills guilty
    of conspiracy and Hills and Winters guilty of filing
    false tax returns. Appellants now appeal various aspects
    of their trial and sentencing. We affirm both Tylman’s
    and Winters’s convictions. We vacate Hills’s convictions
    and remand for further proceedings.
    I. B ACKGROUND
    The investigation of Appellants first began when an
    unrelated organization, Aegis Corporation, caught the
    attention of the IRS. Sometime in the late 1990s, the IRS
    received a tip that Aegis was promoting a tax evasion
    scheme. This tip turned out to be accurate—Aegis was
    in the business of selling fraudulent trust packages.
    The Aegis scheme was designed so that customers ap-
    peared to sell their assets to several trusts when, in
    fact, customers never really ceded control of their assets.
    This scheme was effectuated by requiring customers
    to “purchase” fictitious consulting services when, in
    reality, the “payment” for the services was the means
    by which the customers initially transferred their assets
    into a trust. Then, in most instances, the customers’
    assets were diverted through a series of trusts, which were
    also referred to as common-law business organizations
    Nos. 09-2151, 09-2152 & 09-2153                          3
    (“CBOs”), until those assets ultimately landed in the
    account of an international business company (“IBC”) that
    claimed exemption from United States taxation require-
    ments. The IBCs then reconveyed the assets to the cus-
    tomers under the guise of a gift or a loan, or through
    the customers’ use of a debit card tied to the IBC account.
    These reconveyed assets were never reported on the
    income tax returns of the Aegis customers.
    From 1996 through 2000, IRS Special Agent Michael
    Priess investigated Aegis. Acting under the pseudonym
    “Michael Jordan,” Priess posed as a customer and
    attended a number of Aegis seminars that promoted the
    trust program. In the mid-1990s, Appellant Kenton
    Tylman was working as a salesman for Aegis. It was at
    one of these seminars in 1998 where Priess first met
    Tylman.
    After having success selling the Aegis trusts, in 1999
    Tylman started his own company, Worldwide Financial
    Services (“WFS”), for the purpose of promoting and
    selling Aegis trusts. Appellant Debra Hills was an em-
    ployee of WFS and Tylman’s girlfriend. Appellant Brent
    Winters was an attorney both at WFS and at a successor
    company to WFS, Worldwide Financial & Legal Associa-
    tion (“WFLA”). Winters made an unsuccessful bid for
    Congress in 1998.
    In March of 1999, Priess, suspicious of WFS, arranged
    to meet with Tylman, Hills, and others so that he could
    receive WFS’s assistance in managing Aegis trusts that
    Priess had “purchased” previously. At that meeting,
    Priess explained that he had “paid” $290,000 to an Aegis-
    4                         Nos. 09-2151, 09-2152 & 09-2153
    created business under the guise of management services.
    He told those present that he had underestimated his
    income by $60,000 and that he was hoping to “take care
    of” those additional funds, meaning that he wanted to
    avoid reporting them as taxable income. Tylman offered
    to manage Priess’s Aegis trusts, and also offered tax-
    return-preparation services through an Aegis accountant,
    who, according to Tylman, would be able to “do some
    tax, play games and do some things . . . with [Priess’s
    $60,000].” (Tr. 133-34.)
    After a year of investigation, in late March 2000, IRS
    agents attempted to execute a search warrant at WFS’s
    offices. Before they could execute the search, Tylman
    and Winters objected on the grounds that the list of
    items to be seized was missing from the warrant. Agents
    left to procure a new warrant and returned four hours
    later with a revised warrant in hand. This time, the
    warrant contained a list of items to be seized, but listed
    the incorrect location from which the items were to be
    seized. When agents realized that they had obtained the
    wrong attachment, they left yet again to procure a third
    warrant. That evening, agents finally returned with the
    correct warrant and executed the search, seizing num-
    erous documents and computers.
    Six years later, in April 2006, a grand jury indicted
    Tylman, Winters, and Hills with conspiracy to impede
    the authority of the IRS in violation of 
    18 U.S.C. § 371
    .
    Hills was also charged with an individual count of tax
    fraud based on a tax return she had filed with her then-
    husband in 2000. Winters too was charged with an indi-
    Nos. 09-2151, 09-2152 & 09-2153                          5
    vidual count of tax fraud for his 1998 return. These
    tax fraud counts were brought under 
    26 U.S.C. § 7206
    (1).
    Trial did not commence for two years after the indict-
    ments were issued because of various continuances,
    some sought by Appellants and some sought by the
    government. In June 2008, after a five-week trial,
    a jury convicted Tylman and Hills of conspiracy, but
    acquitted Winters of the conspiracy count. The jury
    also convicted Hills and Winters of tax fraud.
    On appeal, Appellants argue that the district court
    committed various errors, at trial and sentencing. All
    three Appellants claim that their statutory and consti-
    tutional rights to a speedy trial were violated. They
    also complain that the search of WFS’s offices violated
    their Fourth Amendment rights.
    Winters argues that his conviction for filing a false tax
    return was time-barred. He also argues that the prosecu-
    tion committed misconduct by offering certain evidence
    against him, and that the district court abused its dis-
    cretion by admitting that evidence. Winters finally
    argues that the district court imposed an improper sen-
    tence on him.
    Hills argues that there was insufficient evidence to
    support her conviction. She also contends that the pros-
    ecution committed misconduct during its closing ar-
    gument by referring to Hills’s invocation of the Fifth
    Amendment. Finally, Hills complains that the district
    court abused its discretion in denying her motion to sever.
    We take each of these contentions in turn.

    II. A NALYSIS
    A. Statutory Right to a Speedy Trial
    Appellants argue that they were denied their statutory
    right to a speedy trial because numerous continuances
    delayed the trial far beyond the seventy-day period
    prescribed by the Speedy Trial Act (“STA”), 
    18 U.S.C. § 3161
     et seq. We review a district court’s legal interpreta-
    tions of the STA de novo, and its discretionary decisions
    to exclude time for an abuse of discretion. United States
    v. Hemmings, 
    258 F.3d 587
    , 591, 593 (7th Cir. 2001). Unless
    the district court committed legal error, “exclusions of
    time cannot be reversed except when there is an abuse
    of discretion by the court and a showing of actual preju-
    dice.” United States v. Broadnax, 
    536 F.3d 695
    , 698 (7th
    Cir. 2008) (emphasis added) (internal quotation marks
    omitted).
    The STA provides that a defendant must go to trial
    within seventy days of either the issuance of an indict-
    ment or a defendant’s first appearance before a judicial
    officer, whichever is later. 
    18 U.S.C. § 3161
    (c)(1). If a
    defendant is not brought to trial within that seventy-
    day window, the indictment against the defendant must
    be dismissed upon the defendant’s motion. § 3162(a)(2).
    Dismissal may be with or without prejudice. § 3162(a)(1).
    To provide courts with the necessary flexibility to
    accommodate pretrial proceedings, however, the STA
    provides for certain periods of time to be excluded
    from the seventy-day clock. See § 3161(h)(1)-(8). In par-
    ticular, the STA requires that certain periods of time
    Nos. 09-2151, 09-2152 & 09-2153                           7
    “shall be excluded . . . in computing the time within
    which the trial of such offense must commence.” This
    includes “[a]ny period of delay resulting from other
    proceedings concerning the defendant, including but
    not limited to . . . delay resulting from any pretrial
    motion, from the filing of the motion through the con-
    clusion of the hearing on, or other prompt disposition
    of, such motion . . . .” § 3161(h)(1)(D). Time is auto-
    matically excluded under this provision; no showing of
    actual delay in trial is required. United States v. Montoya,
    
    827 F.2d 143
    , 150-51 (7th Cir. 1987).
    The STA also permits a district court to exclude time
    that results from “a continuance granted by any judge
    on his own motion or at the request of the defendant or
    his counsel or at the request of an attorney for the Gov-
    ernment,” if the judge’s decision to grant the continu-
    ance was based on “his findings that the ends of justice
    served by taking such action outweigh the best interest
    of the public and the defendant in a speedy trial.” 
    18 U.S.C. § 3161
    (h)(7)(A). The STA provides a non-exhaus-
    tive list of bases upon which an ends-of-justice continu-
    ance may be granted, § 3161(h)(7)(B), and for time
    to be excludable under this provision, the court must
    undertake a timely consideration of the reasons for the
    continuance, United States v. Napadow, 
    596 F.3d 398
    , 404-
    05 (7th Cir. 2010).
    Appellants claim that the district court erred in ex-
    cluding various days from the STA time-clock. First, they
    claim that the sixteen-day period beginning on May 16,
    2006, and running through May 31, 2006, should not
    8                           Nos. 09-2151, 09-2152 & 09-2153
    have been excluded because the motion filed by Winters
    for a bill of particulars did not actually cause delay in this
    case. Although Appellants acknowledge our holding
    in United States v. Montoya, 
    827 F.2d 143
    , 151 (7th Cir.
    1987), where we held that no showing of actual delay
    was required to exclude the time spent in resolving
    pretrial motions, they urge us instead to adopt the Sixth
    Circuit’s recent decision in United States v. Tinklenberg, 
    579 F.3d 589
    , 598 (6th Cir. 2009). In Tinklenberg, the Sixth
    Circuit held that the plain language of the STA requires
    a showing that actual delay resulted from a pretrial
    motion for the time spent resolving that motion to be
    excludable. 
    Id.
    We decline Appellants’ invitation to change our prece-
    dent. In Montoya, we determined that because § 3161’s
    language was ambiguous, we needed to resort to an
    examination of the legislative history supporting § 3161’s
    enactment to determine whether the filing of a pretrial
    motion automatically stops the speedy trial clock or
    whether a causal relationship is required for an exclusion.
    
    827 F.2d at 151
    . We concluded that Congress intended
    certain classifications of delay to be excludable automati-
    cally, and that, as such, the government need not prove
    a causal relationship between the filing of a pretrial
    motion and the delay in bringing a defendant to trial. 
    Id.
    In Tinklenberg, the Sixth Circuit reached the opposite
    conclusion, finding that § 3161 was unambiguous on its
    face. The court reasoned that because the STA mandates
    that a delay must “result from” a pretrial motion, a
    causal relationship is required for time to be excludable.
    
    579 F.3d at 598
    .
    Nos. 09-2151, 09-2152 & 09-2153                             9
    We disagree, as do most of our sister circuits. See, e.g.,
    United States v. Green, 
    508 F.3d 195
    , 200 (5th Cir. 2007);
    United States v. Hood, 
    469 F.3d 7
    , 10 (1st Cir. 2006); United
    States v. Vo, 
    413 F.3d 1010
    , 1015 & n.2 (9th Cir. 2005);
    United States v. Vogl, 
    374 F.3d 976
    , 985 (10th Cir. 2004);
    United States v. Titlbach, 
    339 F.3d 692
    , 698 (8th Cir. 2003);
    United States v. Dorlouis, 
    107 F.3d 248
    , 253-54 (4th Cir.
    1997); United States v. Arbelaez, 
    7 F.3d 344
    , 347 (3d Cir.
    1993); United States v. Wilson, 
    835 F.2d 1440
    , 1443 (D.C.
    Cir. 1987), abrogated on other grounds by Bloate v. United
    States, 
    130 S. Ct. 1345
     (2010); United States v. Stafford, 
    697 F.2d 1368
    , 1371-72 (11th Cir. 1983). Because we affirm
    the viability of our holding in Montoya, we find that the
    district court’s automatic exclusion of the sixteen days
    running from May 16 to May 31, 2006, was proper. As
    of May 31, 2006, none of the STA’s seventy days were
    consumed.
    Next, Appellants argue that time was improperly
    excluded when Tylman’s counsel filed a motion for a
    continuance. It is asserted that because Tylman had a
    personal right to a speedy trial, his counsel could not
    override his decision to exercise that right. This argu-
    ment is without merit.
    On June 22, 2006, Tylman’s then-appointed counsel, John
    Taylor, filed a motion to continue trial. The motion ex-
    plained that Taylor needed more time to review the case
    and to discuss the matter with Tylman. He further
    stated that the ends of justice would best be served by
    allowing him more time to prepare because adequate
    preparation time would protect Tylman’s rights under
    the Fifth and Sixth Amendments.
    10                         Nos. 09-2151, 09-2152 & 09-2153
    The district court held a hearing on the motion on
    July 14, 2006, at which time it granted the continuance
    and excluded the time from the date of resolution of
    that motion to the date of the new trial, November 27,
    2006. It is the time used to resolve the motion to con-
    tinue—June 22, 2006, through July 14, 2006—that Appel-
    lants argue was improperly excluded.
    On August 12, 2006, Appellants filed a motion to
    dismiss, alleging a violation of the STA. On February 22,
    2007, the district court held a hearing on that motion. At
    that hearing, Taylor testified that prior to his filing the
    continuance, Tylman had made it known to Taylor that
    he did not want to forego a speedy trial. Notwithstanding
    Tylman’s position, however, Taylor thought it best to
    continue the trial. Taylor told the district court that he
    had explained to Tylman that seeking a continuance
    was within his discretion as an attorney, and that he
    believed it was in Tylman’s best interests to have the
    trial continued. Taylor also explained that at the time he
    filed the motion, he had reviewed only 500 pages of the
    thousands of pages of discovery materials that the pros-
    ecution had made available.
    At the conclusion of Taylor’s testimony, the district
    court noted that in addition to Taylor’s request for more
    time, at the hearing on the motion to continue, Hills’s then-
    counsel, Jerold Barringer, had stated that none of the
    defendants were ready to proceed to trial. Based on this
    evidence, the district court concluded that the continu-
    ance had been justified, and therefore, the motion to
    dismiss had to be denied.
    Nos. 09-2151, 09-2152 & 09-2153                          11
    We agree. Certain rights are fundamental, and therefore
    personal, to a defendant. Such rights include the waiver
    of the right to a jury trial, the right to plead guilty, the
    right to testify on one’s own behalf, or the right to take
    an appeal. Jones v. Barnes, 
    463 U.S. 745
    , 751 (1983). Al-
    though Appellants assert that the waiver of a right to a
    speedy trial is among these rights, they are incorrect. The
    right to a speedy trial is certainly an important right, yet
    trial tactics have always been within counsel’s province.
    As we explained in United States v. Gearhart, 
    576 F.3d 459
    ,
    463 n.3 (7th Cir. 2009), “there is no requirement that
    counsel obtain [the defendant’s] consent prior to making
    purely tactical decisions such as the decision to seek a
    continuance.”
    Furthermore, the STA itself recognizes counsel’s ability
    to seek a continuance. The STA states that a district court
    may exclude time resulting from a continuance granted
    “at the request of the defendant or his counsel . . . .” 
    18 U.S.C. § 3161
    (h)(7)(A) (emphasis added). Congress clearly
    recognized that counsel could seek a continuance and
    codified this understanding of trial strategy. We see
    no reason to upset this understanding of the law. Ac-
    cordingly, we find that the district court properly
    excluded the time running from June 22, 2006, through
    July 14, 2006. At that point, only twenty-one days out of
    the seventy-day period had been consumed.
    But Appellants argue that the statements accom-
    panying the district court’s exclusion of time at the
    July 14 hearing failed to satisfy the mandates of
    § 3161(h)(7)(A). Therefore, Appellants claim that the
    12                         Nos. 09-2151, 09-2152 & 09-2153
    time running from July 15, 2006 (the day after the
    hearing on the motion to continue) through July 30,
    2006 (the last date during which no other motions were
    pending) was improperly excluded.
    As mentioned, § 3161(h)(7)(A) requires a court
    excluding time on ends-of-justice grounds to articulate
    its findings on the record. Napadow, 
    596 F.3d at 404-05
    . A
    court need not do so contemporaneously with the ex-
    clusion, but it must do so by the time it rules on a defen-
    dant’s motion to dismiss. 
    Id. at 405
    . If a court fails to
    explain its reasons for excluding time, the time will be
    counted toward the STA’s seventy-day period. 
    Id. at 404
    .
    The STA provides various factors a court may consider
    in deciding that an ends-of-justice exclusion is war-
    ranted. General congestion of a court’s trial calendar
    is an invalid reason for an exclusion. United States v.
    Aviles, 
    623 F.2d 1192
    , 1195 (7th Cir. 1980). Reasons
    that are acceptable include whether the failure to
    grant a continuance would result in a miscarriage of
    justice, whether the case is so complex that adequate
    trial preparation is impossible under the STA’s time
    limits, and whether the failure to continue would deny
    the defendant reasonable time to obtain counsel, or
    would deny counsel the time necessary for effective
    preparation. 
    18 U.S.C. § 3161
    (h)(7)(C).
    At the hearing to resolve Taylor’s (and by extension,
    Tylman’s) motion for a continuance, Taylor put forth
    various reasons why the ends of justice would be served
    by granting the continuance, including the intricacies
    and voluminousness of the case and the seriousness of
    Nos. 09-2151, 09-2152 & 09-2153                         13
    Tylman’s potential punishment. The court agreed with
    Taylor that the case was serious and that the evidence
    was complex. The court then questioned the other
    defense attorneys to ascertain their thoughts on the
    continuance. Both Hills’s counsel, Barringer, and Winters,
    acting pro se, agreed that although they could proceed
    without the continuance, they would prefer not to do so.
    In granting the continuance, the district court stated
    that the complexity of the case supported its conclusion
    that a continuance was necessary. The court noted that
    effective preparation of counsel was a factor it could
    consider, and that without a continuance, it was surely
    opening the door to a later ineffective assistance of
    counsel claim. The district court also determined that
    because the defendants were not in custody, they would
    not be significantly prejudiced by a delay. In setting
    the new trial date, the court also commented that its
    time and schedule were valuable and that no more con-
    tinuances should be granted.
    We find that the district court’s ends-of-justice finding
    was sufficient. The court articulated adequate reasons
    for its decision to grant the continuance, including the
    complexity of the case and the necessity to allow counsel
    adequate preparation. These were proper reasons for
    granting the continuance, and they suffice to meet the
    requirements of § 3161.
    And despite the fact that the court mentioned the defen-
    dants’ status as unincarcerated pre-trial defendants, it
    is clear that the principal reason for the court’s decision
    to grant the continuance was to allow each defendant
    14                         Nos. 09-2151, 09-2152 & 09-2153
    and his or her counsel adequate time to prepare for trial
    in the face of the voluminous and intensive discovery
    record. Its questioning of counsel on this very point
    lends credence to that determination. Because the court’s
    primary concern was adequate trial preparation, we
    save for another day the question of whether a trial
    court may give preference to cases in which the defen-
    dant is in custody at the expense of those cases in
    which the defendant is out on bail.
    We also note that although the court commented on
    its time and schedule, this comment was not the basis
    for its ends-of-justice finding. Instead, the court’s state-
    ment that its time and schedule were valuable was in-
    tended to serve as a warning to the parties that the
    court was disinclined to grant any more continuances.
    The best way to avoid these types of challenges is to
    clearly separate ends-of-justice findings from cautionary
    statements regarding new trial dates; however, because
    its time-management statement was not a reason
    for the district court’s ends-of-justice finding, the court’s
    ends-of-justice finding was not improper.
    As the court’s July 14 ends-of-justice finding was suffi-
    cient, the time between the granting of that motion and
    the filing of subsequent motions was properly excluded.
    At that point in the case, only twenty-one days had
    elapsed from the STA time-clock. Because trial began
    within the seventy-day period, Appellants’ STA argu-
    ment fails. We now turn to Appellants’ constitutional
    speedy trial arguments.
    Nos. 09-2151, 09-2152 & 09-2153                          15
    B. Constitutional Right to a Speedy Trial
    Appellants also argue that they were deprived of their
    constitutional rights to a speedy trial under the Sixth
    Amendment. We review a district court’s legal conclu-
    sions regarding Sixth Amendment speedy trial claims
    de novo, and its factual findings for clear error. United
    States v. Arceo, 
    535 F.3d 679
    , 684 (7th Cir. 2008).
    The constitutional right to a speedy trial is triggered
    when an indictment is returned against a defendant. 
    Id.
    A Sixth Amendment claim of a speedy trial violation
    is analyzed by considering “whether delay before trial
    was uncommonly long, whether the government or the
    criminal defendant is more to blame for that delay,
    whether, in due course, the defendant asserted his right
    to a speedy trial, and whether he suffered prejudice as
    the delay’s result.” Doggett v. United States, 
    505 U.S. 647
    ,
    651 (1992). The length of the delay, however, “is not so
    much a factor . . . as it is a threshold requirement: with-
    out a delay that is presumptively prejudicial, we
    need not examine other factors.” United States v. Loera, 
    565 F.3d 406
    , 412 (7th Cir. 2009) (internal quotation marks
    omitted), cert. denied, 
    130 S. Ct. 654
     (2009). We have de-
    termined that “delays approaching one year [are] pre-
    sumptively prejudicial.” United States v. White, 
    443 F.3d 582
    , 589-90 (7th Cir. 2006).
    In this case, Appellants did not stand trial until two
    years after their indictments were handed down. Be-
    cause two years creates a presumption of prejudice, we
    must now consider the other three Doggett factors to deter-
    mine whether that prejudice amounted to a constitu-
    tional violation.
    16                         Nos. 09-2151, 09-2152 & 09-2153
    1. Blame for the Delay
    When analyzing which party is more to blame for the
    delay, the reason for the delay is generally the focal
    inquiry. United States v. Loud Hawk, 
    474 U.S. 302
    , 315
    (1986). Because “pretrial delay is often both inevitable
    and wholly justifiable,” Doggett, 
    505 U.S. at 656
    , “[d]if-
    ferent weights should be given to different reasons for
    delay . . . .” Arceo, 
    535 F.3d at 684
    . “Delays due to the
    complexity of the case and the large number of defendants
    support a finding that no Sixth Amendment violation
    occurred.” United States v. Bass, 
    460 F.3d 830
    , 836 (6th
    Cir. 2006). And while delays resulting from defense coun-
    sel’s need to prepare are attributable to the defendant,
    see United States v. Brown, 
    498 F.3d 523
    , 531 (6th Cir.
    2007), delays resulting from a trial court’s schedule are
    ultimately attributed to the government, but weighted
    less heavily, Barker v. Wingo, 
    407 U.S. 514
    , 531 (1972).
    Turning now to Appellants’ claim, we must analyze
    each set of delays with those principles in mind. First, the
    court granted a nearly four-month continuance from
    July 14, 2006, through November 27, 2006, at the request
    of Tylman’s counsel, Taylor. Hills’s then-counsel,
    Barringer, also impliedly agreed with the basis of the
    motion—that none of the defense counsel were currently
    ready for trial. And Winters, proceeding pro se, con-
    curred with Barringer’s comments. Because this continu-
    ance was granted to allow trial counsel more time to
    prepare, this delay was attributable to Appellants and
    cuts against their Sixth Amendment argument.
    Second, the court held a hearing on August 7, 2006, in
    which it disqualified Barringer as Hills’s counsel due to
    Nos. 09-2151, 09-2152 & 09-2153                        17
    a violation of the Illinois Rules of Professional Conduct.
    On August 23, 2006, the court held a hearing with Hills
    to assess her efforts in finding replacement counsel.
    Prior to that second hearing, however, the government
    sent a letter to presiding Judge Michael McCuskey, re-
    minding him that he needed to recuse himself because
    of a prior recommendation he made to the United
    States Attorney’s Office that the office investigate
    Winters for possible criminal conduct. Judge McCuskey
    formally recused himself at the August 23 hearing.
    Two weeks later, on September 6, 2006, Judge Michael
    Mihm, who had been assigned to the case, held a tele-
    phone status conference with the parties. At that confer-
    ence, Judge Mihm noted that Winters had filed an inter-
    locutory appeal, alleging STA violations, Hills still did
    not have an attorney, and Taylor had moved to with-
    draw as Tylman’s counsel. Judge Mihm decided that
    it would be premature to schedule a new trial date when
    two of the three defendants were unrepresented, so
    he scheduled a hearing for September 26, 2006, to
    address scheduling and other pending matters.
    At the September 26 hearing, both Hills and Tylman
    requested to represent themselves at trial, and the
    district court agreed. The court then addressed the issue
    of the trial date. Judge Mihm commented that based on
    his experience in conducting tax fraud cases, he was
    concerned that the voluminous nature of discovery and
    complexity of the legal issues would require a trial date
    at least six months out—sometime in April 2007. Tylman
    responded that he foresaw at least nine months of work,
    18                         Nos. 09-2151, 09-2152 & 09-2153
    based on the amount of discovery. Tylman then re-
    quested a trial date no earlier than the end of May, to
    which Judge Mihm responded by inquiring whether
    late June was desirable. Tylman agreed, as did Hills, and
    the district court then scheduled trial for June 25, 2007.
    While this delay of approximately ten months is some-
    what attributable to the government, Appellants share
    most of the responsibility. Judge McCuskey’s recusal was
    attributable to the government, despite its contention
    otherwise, because a judicial recusal is more akin to a
    trial court’s scheduling problem than a defendant’s
    request for more time. Reasoning by analogy from
    Barker, 
    407 U.S. at 531
    , we think the government can be
    properly assessed with this initial delay.
    But because the delay was prolonged by Appellants’
    difficulties in securing replacement counsel, this delay is
    not entirely attributable to the government. Two weeks
    after Judge McCuskey recused himself, Judge Mihm was
    assigned to the case. At that time, two defendants were
    unrepresented and Winters had filed an interlocutory
    appeal. The twenty days that it took for the court to
    resolve these issues are, therefore, attributable to Appel-
    lants.
    The time between September 26, 2006, and June 25, 2007,
    is also attributable to Appellants. It was Appellants who
    requested to represent themselves. It was Appellants who
    needed additional time to sort through the discovery
    materials in preparation for trial. It was Appellants who
    sought the nine-month continuance of the trial date in
    furtherance of that preparation. These nine months
    were therefore attributable to Appellants. As such, we
    Nos. 09-2151, 09-2152 & 09-2153                         19
    think that most of this ten-month delay can be traced
    to Appellants rather than the government.
    Third, there was a delay occurring in April 2007. At that
    time, Appellants sought a continuance, claiming that the
    government was not making available all the discovery
    materials to which Appellants were entitled. On April 25,
    2007, the district court held a hearing on the motion.
    The court concluded that the government was not with-
    holding information, contrary to Appellants’ assertions.
    This delay was not attributable to the government. It was
    Appellants’ mistaken belief that the government was
    withholding information, so Appellants should bear
    the blame for that delay.
    Finally, there were two delays occurring in April 2007
    and again in September 2007, when Appellants sought
    more time to review the massive amounts of documents
    produced during discovery. In fact, the government
    unsuccessfully objected to the September 2007 motion.
    Because these continuances were both granted to allow
    Appellants more trial preparation time, they are attribut-
    able to Appellants.
    We conclude that most of the delay in proceeding to
    trial was attributable to Appellants. We now turn to the
    second Doggett factor.
    2. Assertion of Speedy Trial Rights
    It is evident from Appellants’ various motions and
    arguments that they asserted their rights to a speedy
    20                         Nos. 09-2151, 09-2152 & 09-2153
    trial. We therefore turn to whether they suffered prej-
    udice from the trial’s delay.
    3. Prejudice Resulting from the Delay
    We examine prejudice resulting from a delay in trial in
    light of the interests that the Sixth Amendment seeks to
    protect. The Sixth Amendment right to a speedy trial is
    animated by the need “(1) to prevent oppressive pretrial
    incarceration; (2) to minimize anxiety and concern of
    the accused; and (3) to limit the possibility that defense
    will be impaired.” White, 
    443 F.3d at 591
     (internal quota-
    tion marks omitted). But “[w]hen a defendant is unable
    to articulate the harm caused by delay, the reason for
    the delay . . . will be used to determine whether the
    defendant was presumptively prejudiced.” United States
    v. Mundt, 
    29 F.3d 233
    , 236 (6th Cir. 1994). In fact, as long
    as the government shows reasonable diligence in pros-
    ecuting its case, a defendant who cannot demonstrate
    prejudice with specificity will not show a Sixth Amend-
    ment violation, no matter how long the delay. United
    States v. Howard, 
    218 F.3d 556
    , 564 (6th Cir. 2000); see also
    Doggett, 
    505 U.S. at 656
    .
    With regard to this case, we first note that none of the
    Appellants was subject to pretrial incarceration. That
    factor cuts against them. Next, Hills claims that she
    suffered “great anxiety and concern over this case.” But
    she has offered no evidence of her anxiety besides her
    general assertion that she was so afflicted, so we need
    not give this claim much weight. See, e.g., United States v.
    Nos. 09-2151, 09-2152 & 09-2153                            21
    Frye, 
    489 F.3d 201
    , 213 (5th Cir. 2007) (finding that an
    incarcerated defendant’s uncorroborated claim of anxiety
    was insufficient to establish prejudice); United States v.
    Henson, 
    945 F.2d 430
    , 438 (1st Cir. 1991) (considering only
    “undue pressures” and not the anxiety that normally
    accompanies criminal procedures); Morris v. Wyrick, 
    516 F.2d 1387
    , 1391 (8th Cir. 1975) (same). Finally, Appellants
    claim that their defense was impaired because some of
    their witnesses no longer recalled vividly the events
    surrounding Appellants’ illegal activities. We note, how-
    ever, that because the delays in this case were pri-
    marily attributable to Appellants, they must demonstrate
    specifically how their defenses were prejudiced. Howard,
    
    218 F.3d at 564
    ; see also Doggett, 
    505 U.S. at 656
    . Appellants
    have not made this specific showing.
    Only two of the witnesses Appellants point to testified
    that the passage of time affected their memories. And one
    of those witnesses testified that if provided information
    to help him connect a particular date to a given meeting,
    he would be able to answer defense counsel’s questions.
    Appellants do not, however, point to any testimony by
    either of these two witnesses in which the witness could
    not recall an answer to a particular question.
    Two more witnesses to whom Appellants refer did not
    testify that their memories were less potent because of
    the passage of time. In fact, one witness explained that
    he had trouble remembering events due to injuries sus-
    tained in an airplane crash decades earlier. The other
    testified that his stroke two years prior to trial had
    affected his ability to speak, but he did not testify as to
    the stroke’s effect on his memory.
    22                         Nos. 09-2151, 09-2152 & 09-2153
    Finally, Appellants point to two witnesses who were
    no longer available at trial, but who Appellants claim
    could have assisted their defense. Appellants do not
    state that these witnesses would have helped their
    defense, but rather, only that this testimony might have
    helped their defense. They do not point to any specific
    testimony these witnesses would have offered; they
    only identify speculative testimony entirely unsup-
    ported by evidence. Because Appellants can point to no
    specific testimony that any of these six witnesses
    would have offered but were unable to offer by the time
    of trial, Appellants have failed to prove with specificity
    that they suffered prejudice to their defense.
    As Appellants were responsible for most of the delay
    in their trial date, and as they failed to show that they
    suffered any prejudice, they have also failed to show
    a constitutional speedy trial violation.
    C. Fourth Amendment Suppression
    Appellants also contend that the district court erred in
    denying their motions to suppress evidence obtained
    pursuant to the search warrant executed at WFS. In
    reviewing a denial of a motion to suppress, we examine
    factual findings for clear error and legal questions de
    novo. United States v. Burnside, 
    588 F.3d 511
    , 516-17 (7th
    Cir. 2009).
    The Fourth Amendment mandates that a warrant
    describe with particularity “the place to be searched and
    the persons or things to be seized.” U.S. Const. amend. IV.
    Nos. 09-2151, 09-2152 & 09-2153                            23
    Case law has clarified that “[t]he level of specificity
    must be such . . . that the officers executing the warrant
    are able to identify the things to be seized with rea-
    sonable certainty.” United States v. Sleet, 
    54 F.3d 303
    , 307
    n.1 (7th Cir. 1995) (internal quotation marks omitted).
    Supporting affidavits may supply the particularity re-
    quired, as long as those affidavits are incorporated into
    the warrant. United States v. Jones, 
    54 F.3d 1285
    , 1290 (7th
    Cir. 1995). If evidence is obtained in violation of the
    Fourth Amendment, that evidence may be excluded, see,
    e.g., Arizona v. Evans, 
    514 U.S. 1
    , 11 (1995), but it need not
    be, especially if evidence is obtained by officers acting
    in good faith on their belief that the warrant and their
    execution of it were valid. United States v. Leon, 
    468 U.S. 897
    , 919-21 (1984).
    On March 31, 2000, IRS agents executed a search war-
    rant at WFS’s offices. As mentioned earlier, after their
    first attempt at execution, the officers had to return
    twice because of deficiencies in the first two warrants. The
    third warrant on which the officers acted identified the
    property to be seized as “[v]arious records and docu-
    ments showing Tylman’s participation in a fraudulent
    Trust Scheme, designed to evade Federal Income Taxes
    for the years 1994, 1995, 1996, 1997, 1998, and 1999.” (Gov’t
    App. at 69.) The warrant also contained an attach-
    ment, which specified twenty-five particular types of
    items to be seized. Appended to the warrant application
    was a lengthy affidavit in which IRS Agent Bernard
    Coleman detailed the alleged criminal activity occurring
    at WFS and recited the evidence that supported the
    conclusion that Aegis-related records were located on
    24                         Nos. 09-2151, 09-2152 & 09-2153
    WFS’s premises. Attached to the affidavit was the list
    of items to be seized, which was identical to the list
    contained in the attachment. The items seized included
    five computers and numerous floppy discs. Because of
    time constraints, the agents removed the computers
    from WFS, copied the hard drives over the weekend,
    and returned the computers that Monday.
    Appellants filed motions to suppress the evidence in
    the district court. After a three-day hearing on the issue,
    the court concluded that the list was sufficiently par-
    ticular, finding that because this was a complex finan-
    cial investigation, the warrant had to be broad enough
    to reflect the circumstances of the investigation. The
    district court determined that the affidavit supporting
    the warrant supplied the probable cause necessary, and
    that the evidence was therefore constitutionally obtained.
    Appellants claim on appeal that the warrant authorized
    the seizure of all files and electronic media, but this is
    incorrect. The warrant actually specified the seizure only
    of those electronic devices “capable of storing any of the
    records described above,” which referred to items related
    to conspiracy; tax, mail, and wire fraud; and money
    laundering. (Gov’t App. at 71-76.) The warrant was there-
    fore not as broad as Appellants contend. Furthermore,
    considering the warrant in light of the accompanying
    affidavit and attachment, it is evident that there were
    limits on what could be seized from the electronic me-
    dia. In fact, the warrant specified the seizure of elec-
    tronic business records and documents only, thereby pre-
    cluding the seizure of electronic personal files. Finally,
    Nos. 09-2151, 09-2152 & 09-2153                         25
    Appellants have not identified any particular evidence
    seized that was not authorized by the warrant. On these
    bases, we conclude that the warrant was sufficient and
    that the evidence obtained pursuant to that warrant was
    properly admitted.
    Appellants make one final argument for exclusion,
    alleging that the warrant was deficient because it did not
    specify the manner in which agents were to search the
    electronic media. But the Supreme Court has held that
    generally, the authority to determine how a warrant
    should be executed is best left to the officers performing
    the seizure. Dalia v. United States, 
    441 U.S. 238
    , 257-58
    (1979). That rule is applicable here, and we see no rea-
    son to disturb that rule.
    D. Statute of Limitations
    Winters argues that his conviction for filing a false tax
    return is time-barred by the statute of limitations. We
    review the claimed violation of a statute of limitations
    de novo but give deference to the district court’s factual
    findings. United States v. McGowan, 
    590 F.3d 446
    , 456
    (7th Cir. 2009).
    The offense of filing a false tax return requires the
    government to prove that (1) the defendant made or
    caused to be made a federal income tax return that he
    verified as true; (2) the return was false with regard to a
    material matter; (3) the defendant signed the return
    willfully, knowing that it was false; and (4) the return
    contained a written declaration that it was made under
    26                         Nos. 09-2151, 09-2152 & 09-2153
    penalty of perjury. United States v. Oggoian, 
    678 F.2d 671
    ,
    673 (7th Cir. 1982). A charge of filing a false tax return
    is timely if the indictment charging the offense is re-
    turned within six years of the day on which the offense
    is complete. United States v. Solomon, 
    688 F.2d 1171
    , 1179
    (7th Cir. 1982).
    The date on which an offense is complete, and thus, the
    date on which the statute of limitations begins to run,
    depends on whether the return is timely filed. If a return
    is timely filed, the statute of limitations begins to run
    on the due date of the return. Hotel Equities Corp. v.
    Comm’r, 
    546 F.2d 725
    , 727 n.3 (7th Cir. 1976). For returns
    that are untimely, the operative date is the filing date,
    or the date on which the IRS receives the return. In such
    a case, the statute of limitations begins to run on the
    date that the IRS received the return. Emmons v. Comm’s,
    
    898 F.2d 50
    , 51 (5th Cir. 1990).
    Winters’s 1998 return was late; it was not signed until
    April 3, 2000. Winters testified that he mailed it on the
    same day that he signed the return, but the IRS stamped
    the return with a postmark date of April 6, 2000, and a
    received-on date of April 8, 2000. Because his return
    was untimely filed, the statute of limitations did not
    begin to run until the IRS received the return—April 8,
    2000. Because Winters’s indictment was issued within
    six years of the date the statute of limitations began to
    run—April 6, 2006—Winters’s conviction was not time-
    barred.
    Nos. 09-2151, 09-2152 & 09-2153                           27
    E. Prosecutorial Misconduct
    Winters also alleges that the prosecution committed
    misconduct by offering evidence of his other returns, and
    that the district court erred in admitting this evidence.
    We review the admission of evidence for abuse of dis-
    cretion. United States v. Jumper, 
    497 F.3d 699
    , 703 (7th Cir.
    2007). If a claim of prosecutorial misconduct is made at
    the district court level, we review the district court’s
    refusal to enter a judgment as a matter of law for an
    abuse of discretion. See United States v. Sandoval, 
    347 F.3d 627
    , 631 (7th Cir. 2003). If the defendant does not raise
    the claim of prosecutorial misconduct until appeal, how-
    ever, it is reviewed only for plain error. 
    Id.
    Winters’s first claim of misconduct is that the prose-
    cutor repeatedly asked leading questions and later ac-
    knowledged that she had no evidence to support the
    questions that she asked. He points to no record citations
    and provides us with no specific examples, however,
    so this claim is waived. United States v. Dunkel, 
    927 F.2d 955
    , 956 (7th Cir. 1991) (per curiam).
    Winters next argues that the prosecutor committed
    misconduct by offering, and the district court erred by
    admitting, his tax returns for 1999 and subsequent
    years. Under 
    26 U.S.C. § 7206
    (1), the statute that Winters
    was charged with violating, the false entry must be mate-
    rial. “[A] false statement is material when it has the
    potential [to] hinder[] the IRS’s efforts to monitor and
    verify the tax liability” of the taxpayer, or when it results
    in the underpayment of tax. United States v. Presbitero,
    28                         Nos. 09-2151, 09-2152 & 09-2153
    
    569 F.3d 691
    , 700-01 (7th Cir. 2009) (internal quotation
    marks omitted) (alteration in original).
    The prosecutor offered and the district court admitted
    Winters’s post-1998 tax returns to establish this materi-
    ality element. As an IRS agent testified at trial, the
    $3000 false loss carried over from Winters’s 1998 return
    resulted in an understated tax liability on his 1999 return.
    Therefore, the evidence of Winters’s subsequent tax
    returns was necessary to establish that Winters’s false
    statement was material. It was neither prosecutorial
    misconduct nor an abuse of discretion to admit this
    evidence.
    Winters also objects to the introduction of an unsigned
    income tax return for 1998 that showed only income
    items and did not include the deductions Winters
    included on his signed return. The government argued
    that this unsigned return was necessary to show
    Winters’s willfulness in the filing of the false return,
    which is also a required element under § 7206(1). The
    government claims that Winters used this unsigned
    return to obtain a residential loan from a bank. Because
    this unsigned return included a high income and no
    deductions, so goes the argument, this demonstrated
    that Winters’s inclusion of income was done for the
    express purpose of gaining whatever benefit suited him
    at the time. In contrast, his signed IRS return claimed
    numerous deductions so that he could avoid substantial
    income tax payments. As with the evidence of the subse-
    quent returns, we see neither misconduct nor abuse of
    discretion in the admission of this evidence. The jury
    surely could have concluded that this unsigned return
    Nos. 09-2151, 09-2152 & 09-2153                          29
    helped establish willfulness, and we see no error in
    its admission.
    Finally, Winters claims for the first time that the prose-
    cutor committed misconduct and the court erred by
    allowing the testimony of IRS Agent James Pogue.
    Agent Pogue testified that Winters claimed a mileage
    deduction on his individual return and was also reim-
    bursed by his political campaign for that same mileage.
    Because this is the first time Winters raises this argu-
    ment, he must show that the admission of this testimony
    was plain error. Sandoval, 
    347 F.3d at 631
    . He cannot do
    so, however, because Agent Pogue never asserted that
    this inclusion was false. Rather, he simply noted that as
    he reviewed Winters’s 1998 return, he noticed this
    fact. This testimony comprises three lines in a 2867-page
    transcript. It was not plain error for the court to admit
    a truthful statement that surely had little impact on
    the jury’s verdict.
    Winters also claims that the prosecutor engaged in
    misconduct and the court erred by permitting Agent
    Pogue’s testimony that he could not connect Winters’s
    reported income to that shown on Winters’s financial
    ledgers. This testimony was introduced at Winters’s
    sentencing, however, and so had no ability to influence
    the jury’s verdict, contrary to Winters’s claim on appeal.
    Therefore, this claim is rejected.
    F. Improper Sentence
    Winters finally contends that the district court
    imposed on him an excessive sentence. We review a
    30                         Nos. 09-2151, 09-2152 & 09-2153
    district court’s interpretation and application of the
    guidelines de novo, United States v. Samuels, 
    521 F.3d 804
    ,
    815 (7th Cir. 2008), and once we are assured that the
    application was correct, we review the sentence im-
    posed for reasonableness under an abuse-of-discretion
    standard, United States v. Panaigua-Verdugo, 
    537 F.3d 722
    ,
    724 (7th Cir. 2008). On appeal, however, a within-guide-
    lines sentence is entitled to a presumption of reasonable-
    ness. United States v. Mendoza, 
    576 F.3d 711
    , 723 (7th
    Cir. 2009).
    In applying the guidelines to Winters’s case, the
    district court first looked to the offense of conviction.
    Winters was convicted under 
    26 U.S.C. § 7206
    (1), and
    calculations for that offense are determined using
    U.S.S.G. § 2T1.1. The district court determined, consistent
    with the jury verdict, that the false deduction claimed by
    Winters was in the amount of $34,117. Using § 2T1.1(c)
    Note C, the court then determined that the intended loss
    was twenty-eight percent (the applicable tax rate) of
    $34,117, or $9,552.76. The court then used this tax-loss
    amount to arrive at Winters’s base-offense level.
    Winters complains that the actual loss to the Trea-
    sury was only $450, and therefore, this much smaller
    amount should have been used to calculate his base-
    offense level. However, the guidelines explicitly address
    this point, explaining that intended loss is used to de-
    termine base-offense level, not actual loss. U.S.S.G.
    § 2T1.1(c)(1). The district court therefore properly calcu-
    lated the guidelines range at fifteen to twenty-one
    months’ imprisonment.
    Nos. 09-2151, 09-2152 & 09-2153                           31
    The district court then sentenced Winters to twelve
    months’ imprisonment. Winters nonetheless challenges
    his below-guidelines sentence, arguing that the court
    improperly based his sentence on the conspiracy
    conduct of which he was acquitted. But it is well-settled
    that acquitted conduct may be considered by the sen-
    tencing judge in determining the applicable guidelines
    range. United States v. Watts, 
    519 U.S. 148
    , 152-53 (1997)
    (per curiam). And, in any event, the court made it
    clear that Winters’s sentence was based primarily on
    his tax fraud. Accordingly, this argument is without merit.
    Finally, Winters claims that the court improperly
    ignored the 
    18 U.S.C. § 3553
    (a) factors in imposing the
    sentence that it did. A sentencing court need not
    address every factor explicitly. United States v. Brock, 
    433 F.3d 931
    , 936 (7th Cir. 2006). Rather, it is enough if the
    court gave the factors meaningful consideration in light
    of the evidence as a whole. United States v. Harris, 
    490 F.3d 589
    , 597 (7th Cir. 2007). Here, the court considered the
    nature and circumstances of Winters’s offense, noting
    that Winters’s criminal activity arose out of his effort
    to be elected to Congress. The court also addressed
    the need to promote respect for the law, as well as the
    seriousness of the offense, which was compounded be-
    cause of Winters’s status as an attorney. Because the
    court properly considered the § 3553(a) factors, this
    argument, too, is without merit. Winters’s sentence is
    affirmed.
    32                          Nos. 09-2151, 09-2152 & 09-2153
    G. Sufficiency of Evidence
    Hills contends that the evidence against her was insuf-
    ficient to support her conviction on either count. In ex-
    amining the sufficiency of the evidence, “[w]e review
    the evidence at trial in the light most favorable to the
    government and will overturn a conviction based on
    insufficient evidence only if the record is devoid of evi-
    dence from which a reasonable jury could find guilt
    beyond a reasonable doubt.” United States v. Hampton,
    
    585 F.3d 1033
    , 1040 (7th Cir. 2009) (internal quotation
    marks omitted). This is an onerous burden for an appel-
    lant to bear. See United States v. Morris, 
    576 F.3d 661
    , 665-66
    (7th Cir. 2009).
    We first examine the sufficiency of the evidence sup-
    porting Hill’s conviction for conspiracy. To satisfy its
    burden of showing that Hills engaged in a conspiracy to
    impede the United States under 
    18 U.S.C. § 371
    , the
    government must prove the existence of three elements
    beyond a reasonable doubt: “(1) an agreement to accom-
    plish an illegal objective against the United States; (2) one
    or more overt acts in furtherance of the illegal purpose;
    and (3) the intent to commit the substantive offense, i.e.,
    to defraud the United States.” United States v. Cyprian, 
    23 F.3d 1189
    , 1201 (7th Cir. 1994). In satisfying its burden
    of proof, however, the government may present evidence
    that is entirely circumstantial. United States v. Pazos,
    
    993 F.2d 136
    , 139 (7th Cir. 1993).
    To show the existence of an agreement between
    Hills and Tylman to defraud the United States, the gov-
    ernment presented circumstantial evidence of Hills’s
    Nos. 09-2151, 09-2152 & 09-2153                           33
    role in selling the Aegis trusts. For example, the gov-
    ernment pointed to evidence that Hills made a joint
    sales pitch with Tylman; signed an Aegis Team Agree-
    ment, wherein she agreed to “market and promote mem-
    bership in Aegis”; and bragged to others, including
    Agent Priess, about her marketing of the Aegis plan. The
    government also presented evidence of her financial
    incentives to sell the trust packages, her knowledge
    of the trust schemes, her service as the director or
    creator of several Aegis trusts, her work with Tylman
    in selling and promoting the Aegis packages, her im-
    proper notarization of Aegis documents, her exercise of a
    power-of-attorney for a WFS customer, her sig-
    nature authority over the WFS bank account, and her
    part in changing the name on a flow of income to
    make it appear to belong to a third party.
    Hills’s activities are similar to those undertaken by
    defendants in prior cases that federal courts have
    found to be sufficient to support convictions from
    an evidentiary perspective. For example, we found in
    United States v. Furkin, 
    119 F.3d 1276
    , 1280 (7th Cir. 1997),
    that an involved business relationship, among other
    evidence, was sufficient to sustain a defendant’s con-
    spiracy conviction. Similarly, in United States v. Becker,
    
    569 F.2d 951
    , 962 (5th Cir. 1978), the Fifth Circuit found
    that a defendant’s financial interest in the success of
    a scheme was sufficient circumstantial evidence of par-
    ticipation in the conspiracy. And we found in United
    States v. Goulding, 
    26 F.3d 656
    , 663-64 (7th Cir. 1994), that
    a defendant’s participation in arranging the formation
    of fictitious corporations was sufficient circumstantial
    evidence of his knowledge of the conspiracy.
    34                         Nos. 09-2151, 09-2152 & 09-2153
    Although the evidence that the government presented
    did not involve direct evidence of Hills’s agreement to
    defraud the United States, at the very least, it was strong
    circumstantial evidence of her agreement with Tylman
    to act in a concerted effort to defraud the United States.
    Assuming for the time being (we will address this be-
    low) that Hills had knowledge of the illegality of the
    trusts and intent to sell them, then her willingness to
    promote them certainly could show her agreement to
    conspire against the government.
    Next, we examine whether the government presented
    sufficient evidence to show that Hills engaged in one
    or more overt acts to further the conspiracy’s purpose.
    We begin by noting that there is much overlap between
    the evidence tending to show Hill’s agreement to
    join the conspiracy and her acts taken in furtherance
    thereof. We need not rehash the evidence outlined above.
    It is enough to note that the evidence presented was
    sufficient to establish at least circumstantial proof of
    Hills’s actions in furtherance of the conspiracy.
    Finally, we turn to whether the government presented
    sufficient evidence of Hills’s intent to commit the
    offense of defrauding the United States. During the
    IRS’s search of WFS, the agents found an IRS bulletin
    in Hills’s office warning financial advisors to “[s]teer
    clear of abusive trusts” and informing potential violators
    of possible criminal prosecution. The IRS agents also
    found a Wall Street Journal article detailing the IRS’s
    recent crackdown on abusive trusts; that article specifi-
    cally mentioned business trusts and various holding
    Nos. 09-2151, 09-2152 & 09-2153                             35
    trusts. Additionally, the agents seized an IRS notice
    warning financial advisers against the use of abusive
    trusts and describing the characteristics of those trusts.
    This description included an explanation of trusts used
    to hide the owner’s identity, multiple trusts used to hide
    assets, and trusts that were marketed as a means of ob-
    taining tax benefits despite no meaningful change in
    the taxpayer’s control of his assets. And finally,
    the agents found an advertisement listing Hills as a
    coordinator for a WFS seminar promoting “reduction
    of income tax.”
    The government argued that these documents, in
    concert, tended to show Hills’s intent to defraud the
    IRS. Viewed in the light most favorable to the govern-
    ment, we cannot say that this evidence was insufficient
    to permit the jury to draw the conclusion that Hills
    knew the purpose of the Aegis scheme and intended to
    defraud the IRS by promoting that scheme.
    Because the evidence was sufficient to support the
    jury’s verdict that Hills committed conspiracy to
    defraud the United States, we reject her argument on
    this point. We now turn to her argument that there was
    insufficient evidence to convict her on filing a false tax
    return.
    To prove that Hills willfully filed a false tax return
    under 
    26 U.S.C. § 7206
    (1), the government must demon-
    strate the existence of four elements beyond a rea-
    sonable doubt: (1) the defendant made or caused to be
    made a federal income tax return that she verified was
    true; (2) the return was false as to a material matter; (3) the
    36                        Nos. 09-2151, 09-2152 & 09-2153
    defendant signed the return willfully and knowing it
    was false; and (4) the return contained a written declara-
    tion that it was made under penalty of perjury. Oggoian,
    
    678 F.2d at 673
    . With regard to criminal tax statutes, the
    Supreme Court has defined “willfulness” as “a voluntary,
    intentional violation of a known legal duty.” Cheek v.
    United States, 
    498 U.S. 192
    , 200 (1991). The government
    is permitted to, and often does, prove willfulness
    through circumstantial evidence. United States v. Britton,
    
    289 F.3d 976
    , 981 (7th Cir. 2002).
    Hills does not challenge the sufficiency of the evidence
    as it relates to her entire conviction; instead, she chal-
    lenges only the evidence of her willfulness in filing
    the false return. The government’s evidence of Hills’s
    willfulness consisted primarily of the testimony of her
    estranged husband, Stephen Hills. Stephen testified that
    Hills was responsible for managing the couple’s finances,
    and that her responsibilities included having the tax
    returns prepared. Stephen would provide his wife with
    all of his relevant paperwork, and she would then
    compile it and forward it to the couple’s accountant.
    For the year 2000 (the year of the return on which the
    conviction was based), the Hillses’ return reported their
    income as $30,376. A single Schedule C was attached to
    the return. That Schedule C, used to report the taxable
    value of Stephen’s computer business, reported gross
    receipts of $18,500 and a gross profit of $13,682. It also
    reported substantial expenses, resulting in an overall
    loss of $30,798. The IRS determined that the expenses
    were, in fact, highly inflated; Stephen’s business did not
    Nos. 09-2151, 09-2152 & 09-2153                        37
    lose $30,798 as reported. Because of these inaccura-
    cies, the Hillses’ 2000 income was substantially under-
    reported, showing income of only $194.
    Also compounding the error in the return, the Hillses’
    2000 return did not include a business Schedule C for
    Hills, despite the fact that checks totaling $18,258.66
    were deposited by WFLA and WFS into Hills’s trust
    account—DJH Asset Management—and her personal
    bank account. When the government compared the
    2000 return to the Hillses’ 1999 return, it noticed a dis-
    crepancy as the 1999 return had included a Schedule C
    reporting Hills’s receipt of funds from WFLA and WFS.
    The government argued that based on Hills’s knowl-
    edge that the WFLA and WFS income was taxable—as
    gleaned from her inclusion of these funds on her 1999
    return—her failure to report these same funds on
    her 2000 return proved that her filing a false return
    was done willfully. Our review of the evidence in
    the light most favorable to the government leads to
    our conclusion that a jury could have inferred Hills’s
    intent from this evidence. Stephen’s testimony regarding
    Hills’s responsibility for the finances of the family, as
    well as the differences in her returns for the years 1999
    and 2000, and the substantial tax benefit she received
    from her failure to include a Schedule C with her 2000
    return was more than enough circumstantial evidence
    to establish her willfulness beyond a reasonable doubt.
    Therefore, her second sufficiency of the evidence argu-
    ment also fails. We now turn to Hills’s prosecutorial
    misconduct argument.
    38                          Nos. 09-2151, 09-2152 & 09-2153
    H. Prosecutorial Misconduct
    Hills next argues that the prosecution committed mis-
    conduct when the prosecutors mentioned the defendants’
    invocations of their Fifth Amendment right to remain
    silent during the prosecution’s closing argument. Hills
    did not, however, raise this argument during trial, so we
    review it only for plain error. Sandoval, 
    347 F.3d at 631
    .
    Under our plain-error review, Hills must demonstrate
    that (1) there was error, (2) it was plain, (3) it affected her
    substantial rights, and (4) we should exercise our discre-
    tion to correct that error because it seriously affected the
    fairness, integrity, or public reputation of the judicial pro-
    ceedings. United States v. Olano, 
    507 U.S. 725
    , 732-35 (1993);
    United States v. Jaimes-Jaimes, 
    406 F.3d 845
    , 847-49 (7th
    Cir. 2005). Because we are dealing with a claim of prose-
    cutorial misconduct, Hills must demonstrate that the
    comments at issue were “obviously” or “clearly” improper.
    United States v. Renteria, 
    106 F.3d 765
    , 766-67 (7th Cir.
    1997). And because this review is for plain error only,
    Hills must also show that not only was she deprived of
    a fair trial, but also that the outcome of that trial prob-
    ably would have been different absent the prosecution’s
    remarks. Sandoval, 
    347 F.3d at 631
    .
    The Fifth Amendment protects a defendant’s right
    against compelled self-incrimination by permitting a
    defendant to refuse to testify at her trial. U.S. Const.
    amend. V. To protect this right, the Supreme Court has
    determined that the prosecution may not comment on
    the defendant’s refusal to testify before the jury. By
    putting this stricture in place, the Court has tried to
    Nos. 09-2151, 09-2152 & 09-2153                           39
    ensure that the jury will not infer guilt from a defendant’s
    silence. Griffin v. California, 
    380 U.S. 609
    , 614 (1965). But
    the rule is not so strict as to bar the prosecution from
    commenting indirectly on the defendant’s exercise of
    her constitutional rights in all situations. United States v.
    Ochoa-Zarate, 
    540 F.3d 613
    , 618 (7th Cir. 2008). In order
    to determine the propriety of a prosecutor’s indirect
    reference to a defendant’s constitutional rights, we
    must determine whether the remarks, viewed in context,
    demonstrated the prosecutor’s “manifest intent[]” to use
    the defendant’s invocation of her rights as evidence of
    guilt, or whether the jury would “naturally and neces-
    sarily” view the remark as such. United States v. Willis,
    
    523 F.3d 762
    , 773 (7th Cir. 2008).
    In this case, the prosecution made two references to
    the Fifth Amendment during its closing, despite an
    explicit warning from the district court to refrain from
    referencing Hills’s invocation of her right to remain
    silent. In particular, in summarizing a recording of
    Tylman speaking with Agent Priess, the prosecutor stated:
    And you don’t really need to worry about that
    Fifth Amendment protection unless you’re
    worried that you’re [d]oing something illegal. They
    knew perfectly well precisely what they were
    doing.
    (Appellant App. at 97-98.) The prosecutor also stated:
    There are a number of things that are inconsistent
    with good faith in this case. Hiding things from
    the IRS, hiding records, lying to the IRS, paying
    40                         Nos. 09-2151, 09-2152 & 09-2153
    a little tax to make it look like it’s legitimate,
    creating entities that really do nothing except to
    funnel money through, taking the Fifth Amend-
    ment. In this case, they’re using the Fifth Amend-
    ment not as a shield to protect themselves from
    incrimination, but as a sword to prevent the IRS
    from getting the information that they are
    entitled to.
    (Id. at 99.)
    Hills argues that because neither Tylman nor Winters
    invoked their Fifth Amendment rights, any such refer-
    ences necessarily referred to her, or at least led the jury
    to so conclude. The government counters that the prose-
    cution’s statements regarding the Fifth Amendment
    were not references to Hills’s refusal to testify, but were
    in fact references to statements that Tylman made to
    Agent Priess during the latter’s undercover investigation
    of WFS.
    While we agree with the government that when read
    in context, the statements most likely referred to
    Tylman’s assertions that if investigated, he would simply
    “plead[] the Fifth Amendment,” (Id. at 158), this alone
    does not end our inquiry. As already noted, indirect
    commentary on a defendant’s failure to testify can still
    violate that defendant’s Fifth Amendment rights, de-
    pending on the context in which it is used. United States
    v. Aldaco, 
    201 F.3d 979
    , 987 (7th Cir. 2000).
    What ultimately guides our conclusion that these com-
    ments were made in error was the fact that the prosecu-
    tion cast invocations of the Fifth Amendment in a
    Nos. 09-2151, 09-2152 & 09-2153                          41
    negative light, which is surely the very thing that the
    right against self-incrimination seeks to protect. See
    Griffin, 
    380 U.S. at 614
    . As such, we are unable to say that
    the jury did not “naturally and necessarily” conclude
    that the prosecution’s comments regarding the Fifth
    Amendment referred to Hills, the only defendant who
    did not testify in her own behalf. We therefore con-
    clude that it was error for the government to make these
    references.
    We also find that these statements amounted to plain
    error. First, we note a very simple reason for this con-
    clusion—the district court judge expressly warned the
    prosecution to refrain from any references to the Fifth
    Amendment. The prosecution was clearly aware of this
    restriction, yet made two references to the Fifth Amend-
    ment anyway. Second, and most importantly, this error
    certainly presented more than a “nontrivial possibility”
    that the references were determinative to the outcome
    of the case. United States v. Mannava, 
    565 F.3d 412
    , 414
    (7th Cir. 2009). As mentioned, Hills was the only
    defendant to invoke her Fifth Amendment right. As
    such, it is entirely possible that the jury thought the
    prosecution was referring to Hills, and not Tylman. To
    ensure the viability of the Fifth Amendment by pro-
    tecting a defendant’s right to be free from compelled self-
    incrimination, we must not allow the prosecution to cast
    a defendant’s invocation of the Fifth Amendment in a
    negative light, as this serves only to penalize her for
    exercising that right.
    Because we think that the government’s references to
    the Fifth Amendment tip the scales on the side of plain
    42                          Nos. 09-2151, 09-2152 & 09-2153
    error, we must next analyze whether that error affected
    Hills’s substantial rights. In determining whether the
    error affected Hills’s substantial rights, we apply the
    same factors used in a harmless error analysis; however,
    the burden shifts to the defendant. See United States v.
    Olano, 
    507 U.S. 725
    , 734 (1993). We therefore look to
    (1) the intensity and frequency of the references,
    (2) which party elected to pursue the line of ques-
    tioning, (3) the use to which the prosecution put
    the silence, (4) the trial judge’s opportunity to
    grant a motion for a mistrial or to give a curative
    instruction, and (5) the quantum of other evi-
    dence indicative of guilt.
    Fencl v. Abrahamson, 
    841 F.2d 760
    , 763 (7th Cir. 1988); see
    also 
    id. at 766-67
    .
    Hills argues that the lack of direct evidence, coupled
    with the prosecution’s references to the Fifth Amend-
    ment, demonstrates that if not for the prosecution’s
    comments, she likely would have been acquitted. In
    essence, she is claiming that the evidence of her guilt,
    standing alone, was not enough to convict her and there-
    fore, a conviction would result in a miscarriage of justice.
    Under these circumstances, we must agree.
    The government twice made reference to the Fifth
    Amendment in the face of explicit warnings to avoid
    doing so, the judge did not undertake any curative mea-
    sure to avoid the jury’s improper use of those references,
    and all of the evidence against Hills was circumstan-
    tial. Although we note that the prosecution referenced
    Nos. 09-2151, 09-2152 & 09-2153                         43
    the Fifth Amendment while purportedly discussing
    Tylman’s actions, the countervailing consideration is that
    Hills was the only defendant who invoked her Fifth
    Amendment rights. As such, it seems plausible to us
    that the jury quite possibly equated this reference to
    Hills’s conduct rather than Tylman’s.
    Because we have reached the conclusion that Hills met
    her burden of proving the gravity of the government’s
    error, our only remaining question is whether we
    should exercise our discretion to correct that error be-
    cause it seriously affected the fairness, integrity, or
    public reputation of the judicial proceedings. We think
    that we must intervene to correct the error in this case.
    The government’s references to the Fifth Amendment
    cast insinuations of guilt upon defendants who linger in
    its protections. Were we to allow these sort of references,
    the government would have an incentive to undercut
    a defendant’s Fifth Amendment rights in future cases,
    which is, of course, unfair to defendants. The public
    would be at a disservice because a fundamental pro-
    tection ensured by our Constitution would be severely
    hampered. And the integrity of the judicial system and
    the respect for the rule of law established by our Con-
    stitution would be strained because we would be
    ignoring the very rationale for the Fifth Amendment’s
    existence. We cannot permit the government’s comments
    to pass without consequence under these circumstances.
    We must vacate Hills’s conviction.
    That does not mean, however, that Hills will necessarily
    walk free. Because Hills’s convictions are being vacated
    44                         Nos. 09-2151, 09-2152 & 09-2153
    due to the government’s improper references to the
    invocation of the Fifth Amendment right against self-
    incrimination, there is no double jeopardy bar to
    her retrial. United States v. Doyle, 
    121 F.3d 1078
    , 1083-86
    (7th Cir. 1997). In Doyle, we squarely addressed whether
    the prosecution’s reference to the Fifth Amendment in
    closing arguments amounts to misconduct that would
    bar retrial. 121 F.3d at 1086. We explained that our
    circuit has implicitly rejected the idea that a prosecutor’s
    intent to “prevail at trial by impermissible means” is
    enough to bar retrial. Id. (internal quotation marks omit-
    ted). Instead, we noted our position that the only mis-
    conduct that bars retrial is “the prosecution’s intent to
    abort the trial . . . .” Id. (emphasis added). We declined
    to determine expressly our position, however, because
    Doyle did not present evidence that the prosecutorial
    misconduct at issue in his case was designed to secure
    a victory by resorting to impermissible tactics. Id.
    We also decline to elaborate on this issue today.
    Instead, we find that because the government’s references
    to the Fifth Amendment, although improper, likely were
    intended to refer to Tylman’s use of that Amendment,
    there was no deliberate intent to secure a victory by
    using impermissible tactics. Because we have already
    addressed Hills’s sufficiency of the evidence claims and
    found them to be lacking in merit, there are no other
    obstacles to the government’s retrial of Hills. See id. at
    1083. Her convictions will be vacated and remanded.
    Nos. 09-2151, 09-2152 & 09-2153                         45
    I. Motion to Sever
    Finally, Hills complains that the district court erred in
    denying her motion to sever her case from that of her co-
    defendants. Because we are vacating her convic-
    tions and remanding her case, we need not address
    this argument. When Hills is retried, she will stand
    trial alone. Therefore, any potential error in denying
    her motion to sever is rendered moot by our decision
    today.
    J. Release Pending Appeal
    Prior to oral argument in this case, Tylman filed a
    motion for release pending appeal. That motion was
    ordered to be taken with the case. Because we affirm
    his conviction today, we deny Tylman’s motion as moot.
    III. C ONCLUSION
    We A FFIRM Tylman’s and Winters’s convictions.
    We V ACATE Hills’s conviction and R EMAND for further
    proceedings.
