    OPINION
    ¶1       Plaintiff-taxpayer, Chak Fai Hau, doing business as Joye Chop Suey, appeals from the
    circuit court’s judgment affirming in part the Department of Revenue’s (Department) tax
    assessment for the period from January 1, 2008, through December 31, 2010. For the reasons
    that follow, we affirm.
    ¶2                                       I. BACKGROUND
    ¶3       Hau is the sole proprietor of Joye Chop Suey, a carryout-only Chinese restaurant located
    at 4829 West Chicago Avenue in Chicago, Illinois. The Department assigned Denise Berry to
    audit Hau’s business taxes for the period from January 1, 2008, through December 31, 2010.
    The Department found that Hau fraudulently underreported his total sales during this period
    and issued corrected tax returns requesting Hau pay $206,455 to cover tax deficiencies under
    the Retailers’ Occupation Tax Act (Act) (35 ILCS 120/1 et seq. (West 2014)), penalties for
    fraud and late payment, and accumulated interest. On June 13, 2012, the Department issued
    two Notices of Tax Liability (NTLs) to Hau, covering the tax periods from January 1, 2008,
    through June 30, 2009, and from July 1, 2009, through December 31, 2010, detailing the
    breakdown of the corrected tax assessment.1 Per the instructions on the NTLs, Hau filed a
    protest on July 16, 2012, and requested an administrative hearing. The evidentiary hearing
    before an administrative law judge (ALJ) took place on December 11, 2013.
    ¶4                                   A. The Evidentiary Hearing
    ¶5       The Department limited its case-in-chief to submitting records, certified by the
    Department’s director, into evidence. These records consisted of a completed form titled
    “Audit Correction and/or Determination of Tax Due” and copies of the NTLs issued to Hau.
    The ALJ found that such certified documents were prima facie correct and overruled Hau’s
    counsel’s hearsay objections. The ALJ also asked counsel if he understood that the admitted
    documents established the Department’s prima facie case. Counsel responded that he
    understood but nevertheless argued that a prima facie case was not made because the exhibits
    failed to establish whether the Department employed minimum standards of reasonableness
    to determine Hau’s tax liability. Counsel further complained that the auditor was not present
    to testify. The Department responded once again that the law supported finding the proffered
    exhibits as prima facie correct irrespective of anything else. The ALJ agreed and counsel
    commented, “We’ll see, yeah. I’m—Sure.”
    ¶6       Hau testified, with the help of a Chinese interpreter, that he was 73 years old at the time
    of the hearing. He opened the restaurant in 2001 and operated it with the help of his wife.
    From the restaurant’s opening through early 2012, Hau retained Maria Tai, an accountant
    from First Quality Financial Group, to file his taxes. During the audit period, Hau had two
    part-time employees who assisted with food preparation and other small tasks. His wife
    1
    For January 1, 2008, through June 30, 2009, Hau was assessed $51,995 due in tax; $20,798 for a
    late payment penalty; $51,995 for a fraud penalty; and $11,650.06 due in interest, for a total assessment
    of $136,438.06. From July 1, 2009, through December 31, 2010, Hau was assessed $48,007 due in tax,
    $9658 for a late payment penalty, $24,003 for a fraud penalty, and $2194.15 due in interest, for a total
    assessment of $83,862.15.
    -2-
    worked the front of the store taking orders and “handl[ing] purchase transactions” while Hau
    managed everything else, including all the cooking.
    ¶7         Hau prepared his sales tax returns by calculating total daily sales and reporting those
    figures along with his expenses to Tai on a monthly basis. He did not provide Tai with any of
    the physical sales receipts. Hau also initially testified that he only accepted cash payments
    during the audit period because he did not have the machine to read credit cards, however he
    changed his statement and acknowledged that there were a small percentage of credit
    transactions during the audit period. He later testified that the register machine had been
    stolen at least twice, although he only reported the theft once, and it was unclear during
    which periods of time he did not have a register.
    ¶8         Hau submitted into evidence copies of his tax returns for 2008, 2009, and 2010. The
    copies were signed by a preparer from First Quality Financial Group but did not bear Hau’s
    signature. Hau commented, unprompted, that he did not understand the tax forms and just
    signed what his accountant had prepared. When asked specifically about the Schedule C
    figures, Hau responded, “To be honest, I never see this. I never see that because I have no
    knowledge how to calculate this number.” Hau further testified that although he reported the
    information to Tai, he had forgotten the amounts due to his old age. The Department objected
    to the admission of the tax returns because Hau could not authenticate the documents. The
    ALJ admitted the evidence over the Department’s objection.
    ¶9         Hau also submitted a copy of the restaurant’s menu representing the prices charged
    during the audit period. The most expensive item on the menu cost $16.45, the cheapest cost
    $0.60, and the majority of items cost $3 to $8. He testified that he used four sizes of
    containers, ranging from 8 to 38 ounces, to package food. The extra-large 38-ounce container
    was sparingly used for items like egg foo young. Rice would be packed for free, in a separate
    small or large container, with each purchase of a small or large entree. Some appetizers, such
    as egg rolls, were not packaged in a container at all and were placed in a small white bag
    instead. Hau also gave rough estimates about the percentage each type of item accounted for
    from his total sales, with fried rice at 50%, seafood entrees at 30%, and other meat entrees at
    20%. Hau estimated his average sales revenue to be $300 per day for Monday through
    Thursday, around $600 to $700 on Fridays and Saturdays, and that his profit margin for sales
    averaged 25%. The restaurant was closed on Sundays, holidays, and on slow nights when
    there was no business.
    ¶ 10       Hau testified about his expenses and stated that he would buy containers whenever they
    were on sale and place them into storage. He could not estimate how often he would deplete
    and restock the containers, which came in packs of 500. Hau also estimated that he would
    lose money on 10% of phone orders after the customers failed to pick up and pay for their
    food.
    ¶ 11       Hau was questioned about a previous hearing he had against the Department regarding a
    sales tax issue. It was elicited that in relation to an audit for the period of January 1, 2005,
    through December 31, 2007, Hau and the Department reached an agreement that he would
    reduce the percentage of markup on sales. Hau denied that he had received notice or was
    informed by his accountant about the need for cash register tapes after the first audit.
    However, he stated that, in the last six months, he had begun to maintain records in a new
    way. He then attempted to submit the physical sales receipts and a prepared statement
    recording the daily gross receipts for August 2013. Although Hau testified the figures were
    -3-
    “probably the same” as a monthly statement for the audit period would be, the ALJ sustained
    the Department’s objection and excluded the evidence as irrelevant to the audit period. Hau
    was asked if he also maintained purchase records, to which he stated, “Now we have, yeah,”
    and he indicated that he would have produced them for the hearing if he had been asked.
    Lastly, Hau testified that during the audit he complied fully and turned over all the sales
    receipts and purchase records he had available. He also noted that there was a leak in his
    restaurant’s roof at one point in time and there was water damage to some records, which he
    threw away.
    ¶ 12        After the conclusion of Hau’s testimony, the Department offered into evidence an “Audit
    Narrative” prepared by Berry on April 30, 2012, and filed with the certificate of the
    Department’s director. Berry wrote that during the audit she examined invoices, some guest
    checks, Hau’s personal tax returns and the related Schedule Cs, the monthly sales tax returns,
    bank statements, EDA-20s, as well as numerous documents prepared by Hau in Chinese and
    transmitted to Tai. These self-prepared documents included monthly receipt summaries, cash
    payouts, and inventory purchases as well as yearly recaps of sales/receipts, expenses, and
    gross profit. Berry thus found that “[t]he owner is in control of all figures that go on the
    [monthly sales tax returns] and personal returns.”
    ¶ 13        Berry noted that Hau’s bank deposits and cash payout reports did not match up. She
    calculated that $135,642 of unreported receipts were missing from the bank deposits. Berry
    found that Hau paid for inventory with cash and other expenses and investments were paid
    by money orders. Berry further noted that Hau also retained Tai as a personal financial
    investor and was well diversified. Although Berry worked with Tai at the beginning of the
    audit, Tai expressed that she would stop representing Hau in 2012 citing her company’s
    inability to spare the time needed to continue compliance with the audit.
    ¶ 14        Berry described Hau’s restaurant and her personal experience ordering food for carryout.
    She related that when paying using her debit card, she was provided with a receipt, however,
    she did not receive one when paying with cash. Rather, she noted that customers were given
    their orders with the “guest check” stapled to the bag. These guest checks were written in
    Chinese and copies of the guest checks were turned over for the audit. Berry attempted to
    schedule the receipts based on the June 2010 guest checks despite the checks being out of
    numerical order and her belief that “[t]here’s no control whatsoever for guest checks.” Berry
    calculated receipts totalling $15,200.21 based on the June 2010 guest checks, which did not
    match Hau’s reported receipts of $9941.
    ¶ 15        Berry contacted the suppliers Hau relied on and requested they complete EDA-20s. Berry
    believed that purchase orders for meat and seafood were missing from the documents turned
    over for the current audit because in comparison to figures from Hau’s first audit, meat and
    seafood purchases had decreased around $23,000 annually whereas the amount of rice
    purchased remained the same. As she believed too many purchase orders were missing to
    utilize a markup method, she calculated the tax due by estimating sales receipts under “the
    container method.” She described her calculations as follows: Using 2010 as a test year,
    Berry reviewed invoices from June through August and “scheduled out all of the containers.”
    Berry then calculated the average selling price for the large and small rice orders and
    determined the average monthly receipts based on the number of containers used. From
    there, she multiplied by 12 to get the expected annual total sales receipts. She then calculated
    -4-
    the tax deficiency by subtracting the reported taxable sales receipts from her calculated total
    and multiplying by the sales tax percentage.
    ¶ 16       Berry calculated the total tax due for the audit period as $100,002. She reported that she
    hand-delivered the audit results to Hau and informed him he had 30 days to review the audit
    and make his payment. At that point, Hau had not retained a new accountant and stated he
    would have his new accountant speak with Berry later. Berry’s narrative also referenced
    several documents in the “audit package,” however these documents were not introduced into
    evidence.
    ¶ 17                                 B. The ALJ’s Recommendation
    ¶ 18       The ALJ prepared a 12-page recommendation for disposition in which he found that the
    NTLs admitted into evidence established the Department’s prima facie case. Further, Hau did
    not have books and records available for audit as required by Illinois law. The ALJ
    concluded that, due to Hau’s failure to maintain records, the container method employed by
    the auditor to determine the unreported tax liability and related penalties was a “reasonable”
    method to estimate revenue and the related sales tax. Although Hau disputed the container
    method, Hau’s testimony about his use of the containers without documentary support was
    insufficient to disprove the reasonableness of the auditor’s calculations. The ALJ concluded
    that Hau’s submission of his tax forms was inadequate to establish that the figures listed were
    more accurate or more reasonable than the auditor’s calculations. The ALJ noted that Hau
    had not signed the tax forms and could not testify as to their accuracy. Furthermore, Hau
    testified that his accountant prepared the forms based on information that he calculated and
    submitted without the supporting physical receipts. The ALJ found that in line with case law,
    he could not find Hau’s summary calculations overcame the Department prima facie case.
    ¶ 19       The ALJ also found that the record failed to establish, by clear and convincing evidence,
    that Hau filed his returns with an intent to defraud. The Department had the burden to prove
    fraud, and the ALJ found that the sole support for a fraud penalty stemmed from the auditor’s
    calculation that the net tax reported percentage change was 555%. The auditor’s narrative
    directed the reader to other supporting documents which were not submitted into evidence at
    the hearing. The ALJ believed that a simple misunderstanding on Hau’s part due to the
    language barrier and his advanced age could just as likely explain his accounting errors as
    intent to defraud.
    ¶ 20       In addressing Hau’s remaining contentions, the ALJ found that the Department had not
    violated Hau’s due process rights in relation to waiving the statute of limitations. The ALJ
    noted that the forms indicated the waiver was marked for the benefit of the taxpayer rather
    than the Department, and the Department was not required by statute, regulation, obligation,
    or duty to present the waivers in Chinese or communicate with Hau in Chinese. The ALJ
    found that Hau had his own duty to ensure he understood the agreement before signing.
    Thus, Hau could not complain where he had the opportunity and means to seek assistance
    from counsel or his accountant prior to signing the waivers.
    ¶ 21       The ALJ recommended that the NTLs be revised to eliminate the fraud penalties but
    found that the alleged taxes owed and late penalties due should be finalized as assessed.
    -5-
    ¶ 22                                   C. The Director’s Decision
    ¶ 23       In 2015, Department Director Constance Beard (Director) entered her decision and
    ordered finalization of the NTLs issued to Hau as they were originally entered. Although she
    adopted the majority of the ALJ’s recommendations, the Director believed that the record
    supported a fraud penalty and entered additional findings of facts and conclusions of law in
    accordance with her opinion.
    ¶ 24       The Director gave special consideration to the differences between Hau’s first audit and
    the current audit. The Director found that Hau had been given actual written notice of the
    record-keeping requirements. She believed he realized that if such records were not provided
    the auditor would be forced to use the markup method and roughly estimate sales based on
    purchase records. Thus, she inferred that Hau had intentionally produced fewer purchase
    records in an attempt to reduce the estimated gross sales.
    ¶ 25       The Director further highlighted that Hau provided the auditor with a receipt for her
    purchase on a debit card but not for the cash purchase. She also determined that at the very
    least, Hau fraudulently reported his sales based on the guest checks he had provided to the
    auditor for June 2010, which were totaled to be 150% greater than the reported receipts.
    Lastly, the Director placed emphasis on the fact that the auditor determined that Hau used
    cash from his sales to purchase savings bonds and other personal investments in amounts that
    greatly exceeded the gross receipts reported on the tax returns.
    ¶ 26       Following the Director’s decision, two “Revised Final Assessments” were issued to Hau
    on June 5, 2015. For the tax period from January 1, 2008, through June 30, 2009, Hau was
    assessed as owing $143,117.26 and from July 1, 2009, through December 31, 2010,
    $88,250.28 for a total assessment of $231,367.54 2 due by July 5, 2015. Hau filed a
    complaint for administrative review on July 10, 2015.
    ¶ 27                                      D. Circuit Court Order
    ¶ 28       The circuit court held that the Act and case law established the Department’s prima facie
    case was proven by the certified exhibits. However, the court agreed with Hau that the
    auditor’s methods were “opaque at best” because she did not give a formal accounting or
    mention the exact prices used in her calculations. Given the “rather large estimate” her
    calculations netted, the court expected to see a more thorough work-up in the audit.
    Nevertheless, the court could not rule that the Department failed to meet a minimum standard
    of reasonableness. The court wrote that Hau’s challenge to the calculations lacked
    documentary evidence and could not prove that there was a better way to calculate the
    estimated sales receipts where no books and records existed. Even Hau’s testimony failed to
    mount a sufficient challenge to the auditor’s “container method,” where Hau could not
    describe the frequency of his purchases of containers, the rate at which he used them, or
    adequately describe which containers were used for which items he sold. Although the court
    was sympathetic to Hau, it did not find that the Department’s prima facie case had been
    overcome.
    ¶ 29       As to the fraud penalties, the court overruled the Director’s decision finding that there
    was no clear showing of the prerequisite intent to fraud. Although the Director drew
    2
    The revised final assessment included an additional $100 “Cost of Collection Fee” for each
    reporting period and levied additional interest charges computed through June 5, 2015.
    -6-
    comparisons to another case, the court found that the Director had an aggressive reading of
    the evidence in the record and Hau’s case was distinguishable from case law in which the
    Department had submitted significantly more evidence and the taxpayer had a less believable
    defense. The court would not absolve Hau’s tax liability due to the language barrier and his
    old age but found that such circumstances called into question his intent to defraud the State.
    Thus, the court held that the Department had failed to prove fraud by clear and convincing
    evidence where fraud or general incompetence and ignorance were equally likely
    explanations for Hau’s tax deficiency.
    ¶ 30                                           II. ANALYSIS
    ¶ 31                                       A. Standard of Review
    ¶ 32        When an appeal is taken to the appellate court following entry of judgment by the circuit
    court on administrative review, it is the decision of the administrative agency, not the
    judgment of the circuit court, which is under consideration. See Anderson v. Department of
    Professional Regulation, 
    348 Ill. App. 3d 554
    , 560 (2004). Our statutes mandate that “[t]he
    findings and conclusions of the administrative agency on questions of fact shall be held to be
    prima facie true and correct” and “[n]o new or additional evidence in support of or in
    opposition to any finding, order, determination or decision of the administrative agency shall
    be heard by the court.” 735 ILCS 5/3-110 (West 2014). Thus our courts have held that “it is
    not a court’s function on administrative review to reweigh evidence or to make an
    independent determination of the facts.” Kouzoukas v. Retirement Board of the Policemen’s
    Annuity & Benefit Fund, 
    234 Ill. 2d 446
    , 463 (2009). When an administrative agency’s
    factual findings are contested, the court will only ascertain whether such findings of fact are
    against the manifest weight of the evidence. Cook County Republican Party v. Illinois State
    Board of Elections, 
    232 Ill. 2d 231
    , 244 (2009).
    ¶ 33        Conversely, if the dispute is over an agency’s conclusion on a point of law, the decision
    of the agency is subject to de novo review by the courts. Cinkus v. Village of Stickney
    Municipal Officers Electoral Board, 
    228 Ill. 2d 200
    , 210-11 (2008). A third standard is
    applicable where the dispute concerns the legal effect of a given set of facts, i.e., where the
    historical facts are admitted or established, the rule of law is undisputed, and the issue is
    whether the facts satisfy the statutory standard. A mixed question of law and fact is reviewed
    for clear error. Exelon Corp. v. Department of Revenue, 
    234 Ill. 2d 266
    , 273 (2009). An
    administrative decision will be set aside as clearly erroneous only when the reviewing court
    is left with the definite and firm conviction that a mistake has been committed. 
    Id.
    ¶ 34                                    B. The Auditor’s Narrative
    ¶ 35       As a preliminary matter we address Hau’s arguments regarding the admission of and use
    of the auditor’s narrative during these proceedings. Hau first challenges the admissibility of
    the narrative arguing that it did not constitute competent evidence because the auditor did not
    testify. Hau further contends it was unfair for the ALJ and Director to draw conclusions
    based on the narrative, which was not presented during the Department’s case-in-chief. Hau
    argues that the narrative was not a part of the Department’s prima facie case and therefore it
    was erroneous to cite the narrative in support of finding that Hau failed to rebut the
    Department’s prima facie case. Although Hau raised the issues as evidentiary objections, the
    Act has several applicable provisions which the Department cites in rebuttal to Hau’s
    -7-
    objections. Thus, Hau’s arguments pose mixed questions of law and fact, which we review
    for clear error.
    ¶ 36       First, we find that the plain language of the Act clearly negates Hau’s challenge to the
    auditor’s narrative as competent evidence. Section 8 of the Act states,
    “[t]he books, papers, records and memoranda of the Department, or parts thereof,
    may be proved in any hearing, investigation, or legal proceeding by a reproduced
    copy thereof under the certificate of the Director of Revenue. Such reproduced copy
    shall, without further proof, be admitted into evidence before the Department or in
    any legal proceeding.” 35 ILCS 120/8 (West 2014).
    Hau makes no effort to explain why the auditor’s narrative does not fall under the “books,
    papers, records and memoranda of the Department.” Hau simply repeats the same hearsay
    argument made during the hearing. We find that the auditor’s narrative was prepared as a
    memorandum of the Department detailing the procedures of the audit, certified by the
    Department’s director, and properly admitted into evidence by the ALJ. Under section 8 of
    the Act, the auditor was not required to testify in order to admit the narrative into evidence.
    ¶ 37       Second, we disagree with Hau that the ALJ and Director incorrectly referred to and relied
    on the auditor’s narrative to draw conclusions about the case. We find that Hau’s argument
    amounts to a mere technicality about the presentation of evidence. The Act provides that the
    Department is not bound by the technical rules of evidence during the hearing. See 35 ILCS
    120/8 (West 2014). But see Novicki v. Department of Finance, 
    373 Ill. 342
    , 344 (1940) (this
    statutory provision does not abrogate the fundamental rules of evidence). The provision
    further provides that, “[i]n the conduct of any investigation or hearing, *** no informality in
    any proceeding, or in the manner of taking testimony, shall invalidate any order, decision,
    rule or regulation made or approved or confirmed by the Department.” 35 ILCS 120/8 (West
    2014). Thus, we find no justification for invalidating the administrative decision simply
    because the ALJ or Director relied on evidence introduced in rebuttal in discussing Hau’s
    failure to overcome the Department’s prima facie case.
    ¶ 38       We cannot find any error in the ALJ’s admission of the auditor’s narrative into evidence
    or the ALJ’s and Director’s reliance on the narrative in drawing their conclusions.
    Accordingly, there is no reason to set aside the administrative decision on these claims.
    ¶ 39                                   C. The Prima Facie Case
    ¶ 40       Hau contends that the Department failed to present a prima facie case where the corrected
    tax return and NTLs allegedly proving the prima facie case were based on inadmissible
    hearsay. Hau further challenges the Department’s method of assessment, arguing that it failed
    to meet a minimum standard of reasonableness. In the alternative, Hau argues that he
    factually rebutted the Department’s prima facie case through his credible testimony and the
    submission of his federal income tax returns for the audit period.
    ¶ 41                               1. Corrected Tax Return and NTLs
    ¶ 42       Like his challenge to the auditor’s narrative, Hau’s contention that the exhibits offered in
    the Department’s case-in-chief are inadmissible is negated by the Act. Section 4 of the Act
    expressly provides that:
    -8-
    “In the event that the return is corrected for any reason other than a mathematical
    error, any return so corrected by the Department shall be prima facie correct and shall
    be prima facie evidence of the correctness of the amount of tax due, as shown therein.
    ***
    ***
    Proof of such correction by the Department may be made at any hearing before
    the Department or the Illinois Independent Tax Tribunal or in any legal proceeding by
    a reproduced copy or computer print-out of the Department’s record relating thereto
    in the name of the Department under the certificate of the Director of Revenue. ***
    Such certified reproduced copy or certified computer print-out shall without further
    proof, be admitted into evidence before the Department or in any legal proceeding
    and shall be prima facie proof of the correctness of the amount of tax due, as shown
    therein.” (Emphasis added.) 35 ILCS 120/4 (West 2014).
    Here, the documents submitted were provided along with the certification of the
    Department’s director. The Act is clear that corrected tax returns are admissible and that no
    further proof is necessary. We further find that copies of the NTLs issued and submitted into
    evidence were also admissible under section 8 of the Act as “books, papers, records and
    memoranda of the Department.” See 35 ILCS 120/8 (West 2014). Thus, we find that the ALJ
    properly admitted these documents into evidence under the Act and Hau’s argument for
    setting aside the decision on this claim has no merit.
    ¶ 43       Furthermore, we have strictly construed the statute insofar as establishing a prima facie
    case is concerned. Masini v. Department of Revenue, 
    60 Ill. App. 3d 11
    , 14 (1978). “Illinois
    courts have uniformly sustained a prima facie case based on corrected tax returns.” Mel-Park
    Drugs, Inc. v. Department of Revenue, 
    218 Ill. App. 3d 203
    , 207 (1991); see also Central
    Furniture Mart, Inc. v. Johnson, 
    157 Ill. App. 3d 907
    , 910 (1987). Thus, the ALJ and Director
    correctly interpreted the Act and found that the Department’s submission of corrected returns
    and the NTLs established its prima facie case.
    ¶ 44                            2. Minimum Standard of Reasonableness
    ¶ 45       Hau further challenges the Department’s prima facie case by arguing that the audit
    procedures were arbitrary and capricious resulting in an unreliable assessment. Hau contends
    that the Department’s prima facie case was not substantiated with “sufficient and probative
    documentary proofs” and, therefore, the auditor should have testified to explain and justify
    the amounts Hau was alleged to owe in tax. Hau cites Grand Liquor Co. v Department of
    Revenue, 
    67 Ill. 2d 195
    , 201-02 (1977), in support of finding that the auditor needs to testify.
    He also points to the circuit court’s finding that the auditor’s narrative was “opaque” in
    describing the methods employed to determine tax liability. Thus, Hau argues that the
    narrative was meaningless in establishing whether the Department’s methods of assessment
    met a minimum standard of reasonableness and the prima facie case must fail.
    ¶ 46       If the taxpayer calls into question the method employed by the Department to calculate
    the amount of tax due, then the record must show that the techniques and assumptions that
    the Department used met some minimum standard of reasonableness. Mansini, 60 Ill. App.
    3d at 14. This requirement is tied to section 4 of the Act, which states that, “the Department
    shall examine such return and shall, if necessary, correct such return according to its best
    judgment and information.” 35 ILCS 120/4 (West 2014). However, “[t]he statute does not
    -9-
    spell out any precise method of producing the corrected return.” Puleo v. Department of
    Revenue, 
    117 Ill. App. 3d 260
    , 266 (1983). Hau raises a mixed question of law and fact as to
    whether the Department proved it complied with the statutory requirement of correcting
    Hau’s return using “best judgment and information,” which we review for clear error.
    ¶ 47       At the hearing, the Department did not offer live testimony from the auditor who
    reviewed Hau’s records and calculated his additional tax liability. In lieu of her testimony,
    the Department submitted the narrative she had typed up and submitted regarding her
    procedures and findings. The narrative supported the Department’s argument that the audit
    was performed under a minimum standard of reasonableness. The auditor’s method of
    calculation included scheduling the containers purchased by Hau, calculating the average
    menu prices for items, and estimating gross sales revenue based on the number of containers
    used multiplied by the average sales price for that size container. This method was selected
    because the auditor believed that a significant number of purchase orders for higher priced
    items were missing. The auditor did not believe that the records did not exist or that Hau had
    simply purchased less meat and seafood because other purchases had remained consistent
    between the first time Hau was audited and this current audit. Thus, a decline in production
    and sales could not account for the disparity in the meat and seafood purchases over the
    years. Using this container method, the auditor estimated monthly sales receipts to be
    $34,600. We note that the narrative also discusses a second method of calculation in which
    the auditor reviewed the guest checks provided for June 2010 and found the receipts totalled
    $15,200.21. However, the auditor found that these guest checks were unreliable because
    there was no control for the guest checks, they were not in numerical order, and guest checks
    would be stapled to carryout bags and given to customers. From the estimated monthly sales
    receipts, the auditor was able to compare the reported figures on Hau’s returns and determine
    the amount of underreported sales receipts and tax deficiencies due.
    ¶ 48       After reviewing the record, we find that the Department did not employ arbitrary or
    unreasonable methods to calculate the sales tax owed. The auditor attempted several methods
    of calculations but found that both the markup method and scheduling the guest checks were
    unreliable due to Hau’s poor record keeping. Thus, the Department resorted to the container
    method.
    ¶ 49       In Vitale v. Illinois Department of Revenue, 
    118 Ill. App. 3d 210
    , 212-13 (1983), the court
    recognized that auditor’s calculation method was driven by the taxpayer’s failure to maintain
    adequate records. The court further determined that the method and techniques employed met
    the requirements of the law where they were not “designed by whim or caprice, but rather
    represented a studied effort to reconstruct with limited information, and much hard work, the
    taxpayer’s business records.” 
    Id.
     Similarly here, we find that the auditor was working with
    limited information, which was due to the actions or inactions of the taxpayer himself, and
    engaged in a calculated effort to obtain the best reconstruction possible. Therefore, we find
    that the Director did not commit clear error in accepting the auditor’s container method.
    ¶ 50       Hau’s complaint that the auditor’s testimony was necessary is undercut by previous cases
    that recognized the Department is not required to produce the auditor to prove up the
    Department’s prima facie case. See American Welding Supply Co. v. Department of Revenue,
    
    106 Ill. App. 3d 93
    , 99 (1982) (recognizing that statute does not require the Department to
    produce auditor for testimony); see also A.R. Barnes & Co. v. Department of Revenue, 
    173 Ill. App. 3d 826
    , 832 (1988) (noting that the auditor or someone personally familiar with the
    - 10 -
    case may testify). Although it may be convenient to have a fuller explanation of the
    procedures employed by the auditor, we find that the narrative submitted outlined her method
    of calculation to a sufficient degree that the Director could determine whether the method
    employed met a minimum standard of reasonableness.
    ¶ 51       Further, we reject Hau’s reliance on Grand Liquor, which, as the court discussed in
    Puleo, 117 Ill. App. 3d at 266-67, was limited to a set of circumstances in which “the
    corrected return was based upon data generated by a computer.” Grand Liquor is further
    distinguishable because it concerned whether hearsay evidence could be used to shore up the
    Department’s case where the taxpayer’s books and records were available. Unlike Grand
    Liquor, Hau failed to maintain adequate books and records for the audit.
    ¶ 52                                          3. Hau’s Rebuttal
    ¶ 53       Having found that the Department properly established its prima facie case and
    demonstrated its assessment methods complied with minimum standards of reasonableness,
    we turn to Hau’s contention that he factually rebutted the Department’s corrected assessment.
    Defendant argues that the submitted income tax returns and his credible testimony were
    sufficient to overcome the Department’s prima facie case.
    ¶ 54       The burden was on Hau to present competent evidence to show that the Department’s
    assessment of additional tax liability was incorrect. “ ‘[A taxpayer] may not prevail by
    merely saying [his] own return was correct, ***. Simply questioning the Department of
    Revenue’s return does not shift the burden to the Department of Revenue.’ ” Masini, 60 Ill.
    App. 3d at 15 (quoting Quincy Trading Post, Inc. v. Department of Revenue, 
    12 Ill. App. 3d 725
    , 730-31 (1973)). “[The taxpayer] must produce competent evidence, identified with [his]
    books and records and showing that the Department’s returns are incorrect.” 
    Id.
     at 15 (citing
    multiple cases). “The law is well-settled that a taxpayer cannot overcome the Department’s
    prima facie case merely by denying the accuracy of the Department’s assessments or by
    suggesting hypothetical weaknesses.” Smith v. Department of Revenue, 
    143 Ill. App. 3d 607
    ,
    613 (1986).
    ¶ 55       Hau argued that the container method used by the auditor was flawed and denied the
    estimated sales revenue as astronomically large. However, his challenge to the Department’s
    assessment consists simply of offering copies of his tax returns and his own testimony. These
    returns have little probative value as he could not testify that they were correct and he related
    that the returns were prepared by his accountant based on monthly summaries that he
    generated himself. His testimony further revealed that his accountant did not have access to
    the source material (i.e., the sales receipts) on which the summaries were based. A taxpayer’s
    failure to produce their records permits a negative inference that if the records had been
    produced, they would have reflected unfavorably on the taxpayer. 
    Id.
    ¶ 56       We find that Hau’s testimony and offered evidence amount to no more than a bare
    assertion that the Department’s corrected returns were incorrect. Hau offered no evidence to
    prove the hypothetical weaknesses in the Department’s methods. Although Hau estimated his
    daily sales revenue and testified to the impoverished nature of the neighborhood, he failed to
    provide any documentary support for his claim that he could not possibly meet the estimated
    sale revenue the auditor calculated. We have consistently found that a taxpayer’s oral
    testimony without sufficient corroborative evidence will not rebut a prima facie case.
    Mel-Park Drugs, Inc., 218 Ill. App. 3d at 217; A.R. Barnes & Co., 173 Ill. App. 3d at 835;
    - 11 -
    Smith, 143 Ill. App. 3d at 613. Accordingly, we find that Hau did not factually rebut the
    Department’s prima facie case and the Director did not err in her conclusions to the contrary.
    ¶ 57                              D. Due Process and the Fraud Penalties
    ¶ 58       We briefly note that neither party raised concerns, in the circuit court or in this appeal,
    about the Director’s finding, adopted from the ALJ’s recommendation, that Hau’s due
    process rights were not violated. Thus, we do not address this issue and affirm the Director’s
    finding as written.
    ¶ 59       Similarly, neither party briefed the issue of whether the fraud penalties were properly
    imposed. However, the Director’s decision and the circuit court’s judgment diverge on this
    issue placing this court in a unique position. Under administrative review, we consider only
    the administrative agency’s decision rather than the judgment of the circuit court. See
    Anderson, 348 Ill. App. 3d at 560. The question remains whether we affirm the Director’s
    imposition of the fraud penalties or, conversely, the circuit court’s finding that fraud was not
    proven by clear and convincing evidence.
    ¶ 60       “[U]nder our supreme court rules, both appellees and appellants forfeit any points not
    argued in their initial briefs.” Amalgamated Transit Union v. Illinois Labor Relations Board,
    Local Panel, 
    2017 IL App (1st) 160999
    , ¶ 59 (citing Ill. S. Ct. R. 341(h)(7), (i) (eff. Feb. 6,
    2013)). We have long recognized that an appellate court will not consider a point that has not
    been argued, unless justice calls for it, and this rule of practice is also applicable to appeals
    under the Administrative Review Law (735 ILCS 5/3-101 et seq. (West 2014)). See Village
    of Maywood v. Health, Inc., 
    104 Ill. App. 3d 948
    , 952 (1982). Historically, the effect of the
    dismissal of an appeal for failure of the appellant to file its brief “is an affirmance of the
    judgment of the trial court rendered following a judicial proceeding in which a judge has
    concluded that based upon the law and the facts such a judgment should be entered.” First
    Capitol Mortgage Corp. v. Talandis Construction Corp., 
    63 Ill. 2d 128
    , 131 (1976). Although
    we are instructed under Administrative Review Law to consider only the agency’s decision,
    neither party has taken issue with the fact that the Director’s decision on the imposition of the
    fraud penalty was overturned. Thus, we find that, in this instance, it is appropriate to affirm
    the circuit court’s judgment in its entirety, and we also reverse the fraud penalties.
    ¶ 61                                      III. CONCLUSION
    ¶ 62      For the reasons stated, we affirm the circuit court’s judgment.
    ¶ 63      Affirmed.
