    Before: GILMAN, ROGERS, and STRANCH, Circuit Judges.
    RONALD LEE GILMAN, Circuit Judge. Susan Sperl, the owner of the accounting-
    services firm SusanTax, was accused by the IRS of engaging in several schemes to help her clients
    falsify their tax returns. Following a jury trial on two of the counts against her and a bench trial on
    the five remaining counts, she was convicted on all seven counts of conspiracy and tax fraud.
    On appeal, Sperl seeks to reverse each of her convictions. She claims that the district court
    abused its discretion by improperly admitting, in the jury trial, hearsay testimony regarding a prior
    consistent statement of a prosecution witness and, in the bench trial, by allowing unduly prejudicial
    evidence of Sperl’s prior bad acts. Sperl also asserts that the government did not present sufficient
    evidence of her guilt to support a conviction on any count. As for her 36-month sentence, Sperl
    contends that the district court erred by imposing enhancements for obstruction of justice, use of
    No. 10-5753
    United States v. Sperl
    sophisticated means, and having a leadership role in the offense. For the reasons set forth below,
    we AFFIRM the judgment of the district court.
    I. BACKGROUND
    Sperl was charged in a nine-count indictment in April 2007. Two of the counts—6 and
    7—were later dismissed by the government. The remaining counts involved three separate schemes
    to falsify income-tax returns submitted to the Internal Revenue Service (IRS). Counts 1 and 2 were
    tried before a jury, but Sperl waived her right to a jury for Counts 3, 4, 5, 8, and 9, choosing a bench
    trial instead. Sperl was convicted on all seven remaining counts during the course of the two
    separate trials. The details of each count are set forth below.
    A.      Counts 1 and 2
    In Counts 1 and 2 of the indictment, Sperl was alleged to have violated 18 U.S.C. § 371 and
    26 U.S.C. § 7206(2) by conspiring with codefendant David Michaels to assist Bryan Wolf and
    Harold Strong, the owners of InSite Services, in falsifying their federal income-tax returns. Wolf
    and Strong each pleaded guilty to one count of conspiracy to commit tax fraud and agreed to
    cooperate with the government by testifying against Michaels and Sperl in exchange for more lenient
    sentences. At trial, Wolf and Strong testified to the following:
    Federal tax law required Wolf and Strong to declare InSite’s earnings on their personal
    income-tax returns because InSite was an “S” corporation. In 2001, Wolf and Strong were paying
    at least 39% of their income in taxes and were seeking ways to reduce their tax liabilities. They
    discussed ideas for reducing their taxes with Michaels, the owner of Mid-Atlantic Personnel. Mid-
    Atlantic provided InSite with health-benefits plans, insurance, and 401(k) plans. Michaels suggested
    -2-
    No. 10-5753
    United States v. Sperl
    that Wolf and Strong move their money into offshore accounts, where it would be “undetected by
    the IRS.” He recommended Sperl as an accountant who could facilitate transferring InSite’s taxable
    income overseas.
    The plan called for InSite to write a check to Mid-Atlantic, “providing an additional layer of
    separation.” Michaels would then write a check to Sperl, Sperl would cash the check and transfer
    the money through several accounts until the funds landed in an overseas account, and then Sperl
    would give Wolf and Strong access to the account through a debit or credit card. The final step of
    the plan involved Wolf working with Michaels to write off the funds as if InSite had spent them on
    a legitimate tax-deductible item, thereby reducing their taxable incomes.
    In September 2001, Wolf and Strong contacted Sperl for the first time, with Michaels
    participating in the phone call. The “gist of the conversation was . . . how to transfer the funds
    without the IRS finding out about it.” During the call, Wolf and Strong were assured that Michaels
    and Sperl “had done it previously and were successful a number of times, and . . . that Ms. Sperl
    would transfer the money through a number of her trust accounts, combine it with other funds, you
    know, take it away and basically provide a number of intermediary transactions to disguise the whole
    thing so we would not be caught.” Wolf and Strong knew that this was tax evasion and were both
    worried about the IRS taking action against them. But at no time during the call did anyone
    affirmatively state that this scheme was illegal.
    Wolf and Strong initially decided to move $100,000 offshore. They sent the money to
    Michaels, who immediately transferred $80,000 of it to Sperl. Sperl told them that she would take
    $40,000 as a onetime setup fee ($20,000 from both Wolf and Strong), “and then 10% of any money
    -3-
    No. 10-5753
    United States v. Sperl
    transferred thereafter.” Michaels subsequently provided Wolf and Strong, per Wolf’s request, with
    an invoice stating that InSite had paid Mid-Atlantic $100,000 for research-and-development services.
    Wolf then gave the invoice to InSite’s tax accountant to ensure that the accountant deducted the
    $100,000 from InSite’s gross income. But Wolf knew that InSite had in fact incurred no such
    expense.
    Approximately seven weeks after Michaels transferred the $80,000 to Sperl, the three men
    had trouble reaching Sperl to find out where the money was. Wolf and Strong were very upset
    because they had been promised that Sperl would set up accounts in a timely manner so that they
    could access their money. By December 2001, they “didn’t have any accounts and didn’t know
    where [their] money was.” Michaels sent Sperl the following fax on December 17, 2001:
    In our conference call you affirmed your ability to facilitate this. Now, seven weeks
    later you are telling us nothing has happened and you don’t know where the money
    is.
    ....
    When you tell me you sent a money order out of the country to a non-proven source
    that talks to you every other day . . . , that’s crazy. A person of your experience
    would never send money orders as good as cash and four days later not have a
    response from the recipient and had not canceled the money order . . . [or] pay[ ] for
    wires that are not accepted by the bank in Zurich.
    ....
    My understanding was that we received $50,000 each, setup of [$]20,000, . . . minus
    . . . a total cost of [$]2,500[. Thus the] balance to be deposited per account equals
    [$]27,500.
    Wolf and Strong, however, never received the amount stated above from Sperl. But Sperl
    did eventually set up two accounts for them in a Tennessee bank, each with $1,500, and provided
    them with debit cards to withdraw the money. She told Wolf and Strong that she kept the total
    deposit under $10,000 to avoid any reporting to the IRS, but no other deposits were ever made. The
    -4-
    No. 10-5753
    United States v. Sperl
    accounts were then suddenly closed, and Sperl informed Wolf that the IRS had seized all of her
    accounts. Sperl urged Wolf not to worry because she had told the IRS agents that Wolf and Strong
    were setting up a legitimate coffee-bean or textiles business and that no money had left the United
    States. When Wolf and Michaels were later contacted by the IRS, Michaels told Wolf to “stick” to
    Sperl’s coffee-beans-and-textiles story.
    B.     Counts 3, 4, and 5
    In Counts 3, 4, and 5, Sperl was charged with participating in another illegal tax scheme.
    This time her alleged coconspirator was Michael Ray, a coowner of Tender Loving Nurses (TLN),
    a Texas company that contracted with hospitals in the Houston area to provide them with critical-
    care nursing staff. Sperl had been preparing Ray’s personal income-tax returns for a few years
    before he founded TLN. In November 2000, Ray asked Sperl to prepare TLN’s 2000 tax return.
    The indictment charged Sperl and Ray with “engaging in transactions to create the
    appearance of legitimate business expenses for TLN in an attempt to fraudulently understate TLN’s
    business income.” In Count 3, Sperl and Ray were charged with conspiracy under 18 U.S.C. § 371.
    Sperl was charged in Count 4 with willfully preparing—aided and abetted by Ray—a fraudulent
    Form 1065 with TLN’s 2000 partnership income-tax return, in violation of 26 U.S.C. § 7206(2). In
    Count 5, Sperl was charged with aiding and abetting Ray in knowingly making and subscribing the
    falsified Form 1065, in violation of 26 U.S.C. § 7206(1). Ray pleaded guilty to conspiracy to
    commit tax fraud pursuant to a plea agreement and agreed to cooperate with the government in
    exchange for a more lenient sentence. The following is a summary of Ray’s testimony at trial
    regarding the alleged conspiracy:
    -5-
    No. 10-5753
    United States v. Sperl
    Sperl traveled to Houston in November 2000 to determine TLN’s quarterly payroll taxes.
    After she reviewed TLN’s records, she told Ray that she could help him save money on his year-end
    taxes. Sperl estimated that TLN would have a profit of $240,000 for the year. On cross-
    examination, Ray could not recall how, in November, Sperl had come up with that estimate.
    Sperl instructed Ray to write a check made out to her for $140,000 and to write in the memo
    section that it was for accounting and legal fees. She told Ray “that no one could tell [him] how
    much she could charge [him] for the services that she provided.” But Sperl did not perform
    $140,000 worth of services. She immediately cashed the check and then had a $140,000 cashier’s
    check made out to Ray as a loan. Sperl told Ray that she had done this type of transaction before and
    never had any problems with it.
    With the remaining $100,000 in profit for the year 2000, Ray made a check out to Sperl in
    that amount, again writing “accounting and legal fees” in the memo section. Sperl immediately
    provided Ray with three checks for $33,000 apiece. Each check had written on it “Investment and
    loan number” followed by the numeral 1, 2, or 3 respectively. But there was no actual loan. Ray
    was to cash the three $33,000 checks once his $100,000 check to Sperl had cleared. Sperl kept the
    remaining $1,000 as a fee. She provided Ray with an invoice for $100,000, but she never provided
    $100,000 worth of services to TLN. Sperl told Ray that “she could bill [him] for whatever she
    wanted and then she could give [him a] loan back if she wanted.”
    Ray did not receive TLN’s 2000 year-end tax return from Sperl until the fall of 2001. (The
    record does not contain any explanation for why TLN’s 2000 tax return was prepared so late in
    2001.) On the return, Sperl had deducted $240,000 from the actual net income as retirement-plan
    -6-
    No. 10-5753
    United States v. Sperl
    expenses, leaving TLN with a falsified net income of $6,140. Ray knew at the time he filed TLN’s
    tax return that the return was false. Sperl also prepared Ray’s 2000 personal tax return, which
    reported that Ray’s share of profits that year was $3,070. But Ray knew at the time that he had
    earned much more than that.
    At around the same time that Sperl was preparing his tax return, Ray was attempting to obtain
    a mortgage for a home that he wished to purchase for $440,000. He told her that he needed a tax
    return to submit to the mortgage company. Sperl told him that she would prepare another version
    of TLN’s 2000 tax return for Ray to provide to the mortgage company. On that version, Sperl
    showed the net income for TLN as $246,140, which was exactly $240,000 more than the net income
    on the version filed with the IRS.
    C.     Counts 8 and 9
    In Counts 8 and 9 of the indictment, Sperl was charged with aiding in the preparation of
    fraudulent 2003 and 2004 tax returns for her clients, John and Deborah Dotson, in violation of 26
    U.S.C. § 7206(2). The Dotsons were not operating any business in those years, and they never told
    Sperl that they were. Nevertheless, the Dotsons’ 2003 and 2004 tax returns stated that they had
    $8,000 and $5,000, respectively, in net income from a maintenance business. By having the business
    income declared on their tax returns, the Dotsons were able to receive a bigger refund because the
    added income enabled them to qualify for the earned-income tax credit. Sperl also received a larger
    fee because of the greater refund, according to Deborah Dotson.
    -7-
    No. 10-5753
    United States v. Sperl
    The Dotsons did not provide the business-income figures to Sperl. In fact, Deborah Dotson
    testified that her husband had only one lung and was too ill with chronic obstructive pulmonary
    disease and emphysema to run any business. He died in March 2009.
    D.      Sentencing
    Following Sperl’s convictions on the seven counts, the district court held a sentencing
    hearing. The Presentence Report prepared for the hearing showed that Sperl’s base offense level
    under the U.S. Sentencing Guidelines was 20. Four sentencing enhancements added 8 points to the
    base offense level and brought the total offense level to 28. With a criminal history category of I,
    the Guidelines advisory range for Sperl’s sentence was 78 to 97 months of imprisonment.
    Sperl, however, challenged three of the four enhancements recommended in the Presentence
    Report. She claimed that she did not qualify for the obstruction-of-justice enhancement under
    U.S.S.G. § 3C1.1, the sophisticated-means enhancement under U.S.S.G. § 2T1.4(b)(2), or the
    leadership-role enhancement under U.S.S.G. § 3B1.1(c). The district court overruled her objections
    but, because of various mitigating factors, ended up sentencing Sperl to 36 months in prison, less
    than half of the low end of the applicable Guidelines range. This timely appeal followed.
    II. ANALYSIS
    On appeal, Sperl challenges both her convictions and her sentence. She argues that the
    district court erred in an evidentiary ruling made during the jury trial and in one made during the
    bench trial. Sperl also claims that there was insufficient evidence to convict her on any of the counts.
    As for her sentence, Sperl insists that the district court improperly imposed three of the four
    sentencing enhancements. Each of her arguments is addressed in turn below.
    -8-
    No. 10-5753
    United States v. Sperl
    A.     Prior consistent statement admitted during the jury trial
    Sperl first argues that the district court abused its discretion in the course of the jury trial on
    Counts 1 and 2 by permitting InSite’s corporate attorney, Stephen Jacobson, to testify regarding
    certain out-of-court statements made by Wolf. Jacobson represented Wolf during an IRS interview
    regarding Wolf’s business relationship with Sperl. At trial, the government called Jacobson to testify
    about what occurred during that interview.
    Jacobson testified that, before the IRS interview, Wolf had told him that Wolf and Strong had
    given money to Sperl to invest in coffee beans or textiles. During the interview, according to
    Jacobson, Wolf told the IRS agents the same story. The agents then showed Wolf falsified invoices
    from Mid-Atlantic Personnel for research-and-development expenses that had nothing to do with
    coffee beans or textiles. Upon seeing these documents, Jacobson became “concerned that Mr. Wolf
    might have some criminal exposure,” so he asked for a break to confer with Wolf. Jacobson testified
    that, while he was conferring with Wolf, Wolf told him that
    the arrangements with Mr. Michaels and Ms. Sperl had nothing to do with [an] actual
    business opportunity, but, in fact, they had been presented with a proposal that they
    would receive an invoice for services or [an] investment [but] that in fact . . . the
    monies were going to be channeled through Mr. Michaels and Ms. Sperl and be set
    up in offshore bank accounts to which they would have access through credit or debit
    cards of some sort; and that they had, in fact, transmitted money with no intention of
    making any business investment but rather having the money offshore and some
    documentation so they could take a deduction.
    Sperl objected to this testimony as hearsay, but the district court overruled the objection on the
    ground that Sperl had “made a very broadside attack on [Wolf’s] credibility” and, therefore, the
    -9-
    No. 10-5753
    United States v. Sperl
    testimony was permitted as a “prior consistent statement” under Rule 801 of the Federal Rules of
    Evidence.
    Rule 801(d)(1)(B) provided at the time of Sperl’s jury trial that “[a] statement is not hearsay
    if . . . the statement is . . . consistent with the declarant’s testimony and is offered to rebut an express
    or implied charge against the declarant of recent fabrication or improper influence or motive.” Fed.
    R. Evid. 801(d)(1)(B) (2008). To qualify as a prior consistent statement, “the declarant must have
    made [the statement] before the motive to fabricate or improper influence or motive arose.” United
    States v. Toney, 
    161 F.3d 404
    , 408 (6th Cir. 1998). Sperl contends that the district court erred by
    failing to determine whether Wolf’s statements to Jacobson were made before or after he had the
    motive to lie. She further claims that Wolf’s motive to lie arose during his interview with the IRS,
    which was just prior to his conference with Jacobson.
    An improper admission of testimony warrants reversal, however, only if the error was
    prejudicial. United States v. Trujillo, 
    376 F.3d 593
    , 611 (6th Cir. 2004). That is, reversal is
    appropriate only if the error “more probabl[y] than not . . . materially affected the verdict.” 
    Id. Sperl argues
    that the improper admission was prejudicial because there was “no effective impeachment
    of the inadmissible hearsay elicited from Jacobson,” and because the alleged hearsay, along with the
    live testimony from Wolf that it corroborated, were the only nonspeculative evidence demonstrating
    that Sperl had the requisite intent to commit tax fraud. She claims that the remaining evidence, “at
    worst, demonstrates that [she] attempted, unsuccessfully, to invest [InSite’s] money in coffee beans
    or textiles . . . .”
    -10-
    No. 10-5753
    United States v. Sperl
    Sperl, however, overstates the weight of Wolf’s out-of-court statements to Jacobson by
    ignoring the ample evidence presented from other sources that confirmed Wolf’s direct testimony
    about Sperl’s intent. For example, Strong corroborated nearly all of Wolf’s testimony, including
    Wolf’s assertion that Sperl had made up the coffee-bean-and-textiles cover story. In addition, the
    fax sent to Sperl by Michaels demanding that she explain what happened to the $100,000 never
    mentions anything about coffee beans or textiles. Patrice Ancelot, Sperl’s assistant, also testified
    that Sperl never mentioned anything about coffee beans or textiles when she told him to find offshore
    accounts for InSite’s money. Thus, even if the admission of Jacobson’s testimony was improper,
    it was harmless and does not warrant a reversal. We therefore have no need to determine whether
    the statements made by Wolf to Jacobson were properly admitted.
    B.     Evidence of prior bad acts admitted during the bench trial
    Sperl next challenges an evidentiary ruling made in the course of the bench trial on Counts
    3, 4, 5, 8, and 9. At that trial, the government sought to introduce evidence that Sperl had prepared
    false tax returns in the past for Phillip Ibanez, Fred Sartuche, and Megan Vasquez. Sperl objected
    to the admission of these alleged prior bad acts. The district court overruled her objection,
    concluding that the evidence was admissible under Rule 404(b) of the Federal Rules of Evidence to
    prove Sperl’s specific intent to falsify the Dotsons’ tax returns as charged in Counts 8 and 9. We
    review the admission of evidence relating to prior bad acts under the abuse-of-discretion standard.
    United States v. Hardy, 
    643 F.3d 143
    , 150 (6th Cir. 2011).
    Rule 404(b) of the Federal Rules of Evidence provided at the time of Sperl’s bench trial that
    “[e]vidence of other crimes, wrongs, or acts is not admissible to prove the character of a person in
    -11-
    No. 10-5753
    United States v. Sperl
    order to show action in conformity therewith. It may, however, be admissible for other purposes,
    such as proof of motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of
    mistake or accident . . . .” Fed. R. Evid. 404(b) (2010). Before admitting Rule 404(b) evidence, the
    district court must (1) “make a preliminary determination regarding whether there is sufficient
    evidence that the ‘other acts’ took place,” (2) “determine whether those ‘other acts’ are admissible
    for a proper purpose under Rule 404(b),” and (3) “determine whether the ‘other acts’ evidence is
    more prejudicial than probative.” United States v. Bell, 
    516 F.3d 432
    , 440-41 (6th Cir. 2008)
    (internal quotation marks omitted).
    Sperl argues that the district court erred in applying steps one and three. She first contends
    that “[t]he proof at trial called into serious question whether Sperl knowingly prepared tax returns
    with false deductions for Megan Vasquez, Fred Sartuche, and Phillip Ibanez.” At trial, however,
    there was ample proof that Sperl had knowingly falsified all three witnesses’ tax returns. Vasquez
    testified that Sperl prepared her 2002, 2003, and 2004 personal income-tax returns and that, after
    being audited by the IRS, Vasquez discovered that Sperl had made several improper deductions from
    Vasquez’s taxable income in those years. Importantly, Vasquez testified that she provided no
    information to Sperl indicating that Vasquez qualified for those deductions. In other words, Sperl
    had no basis to believe that the deductions were accurate.
    Sartuche’s testimony was similar. Sperl prepared his 2001, 2002, 2003, and 2004 personal
    income-tax returns and deducted business losses for a fishing business that Sperl knew he did not
    have. In fact, he testified that Sperl told him specifically that he should think about forming a fishing
    -12-
    No. 10-5753
    United States v. Sperl
    business. Sartuche said that, following an audit, he had to pay the IRS approximately $27,000 in
    back taxes and penalties for those erroneous deductions.
    Much like the other two witnesses, Ibanez testified that he had many improper business
    deductions on his 2001, 2002, 2003, 2004, and 2005 personal income-tax returns that Sperl had
    prepared for him. Ibanez testified that he provided no information to Sperl to indicate that he
    qualified for those deductions, and that he was paying back taxes to the IRS for those years at the
    time of the trial.
    Some of the direct testimony by Vasquez, Sartuche, and Ibanez was undercut on cross-
    examination by certain inconsistencies or memory lapses. But the evidence was still sufficient for
    a rational factfinder to conclude that Sperl had the specific intent to falsify the tax returns in
    question. See 
    Bell, 516 F.3d at 441
    (holding that proof of the prior bad acts is sufficient “if the jury
    can reasonably conclude that [they] occurred”).
    Sperl also asserts that the evidence was unfairly prejudicial.          But a district court’s
    determination that the probative value of Rule 404(b) evidence is not substantially outweighed by
    its unfair prejudice “is afforded great deference.” 
    Id. at 445.
    “‘Unfair prejudice’ . . . means an undue
    tendency to suggest a decision on an improper basis, commonly, though not necessarily, an
    emotional one.” United States v. Hathaway, 
    798 F.2d 902
    , 909 (6th Cir. 1986) (internal quotation
    marks omitted). Because this evidence was admitted during a bench trial, there was little danger of
    any prejudicial impact. See United States v. Hall, No. 98-6421, 
    2000 WL 32010
    , at *2 (6th Cir. Jan.
    4, 2000) (per curiam) (unpublished opinion) (noting that undue prejudice was unlikely in a bench
    trial where “the application of the unfair prejudice portion of Rule 403 has been seen as an
    -13-
    No. 10-5753
    United States v. Sperl
    unnecessary and ‘useless procedure’” (quoting 22 Charles Alan Wright & Kenneth W. Graham, Jr.,
    Federal Practice and Procedure § 5213 (1978 & Supp. 1999))).
    Moreover, because Sperl claimed that she truly believed that the Dotsons ran a maintenance
    business and that she properly added the business’s income to their tax returns, the probative value
    of the other-acts evidence was significant. See United States v. Mitts, 396 F. App’x 296, 300 (6th
    Cir. 2010) (holding that the taxpayers’ testimony of their accountant’s uncharged fraud was more
    probative than prejudicial because the testimony “belied his defense that the returns reflected his
    good-faith understanding of each taxpayer’s situation, as well as his suggestion that the taxpayers
    had somehow mislead him”). Sperl therefore failed to demonstrate that the testimony of Ibanez,
    Sartuche, and Vasquez was unduly prejudicial.
    In sum, Sperl’s challenge to the “other acts” evidence admitted pursuant to Rule 404(b) is
    without merit. We therefore conclude that the district court did not err in considering the testimony.
    C.     Sufficiency of the evidence to convict Sperl
    In a final challenge to her convictions, Sperl claims that there was insufficient evidence
    presented at either the jury trial or the bench trial to convict her on any of the counts charged. We
    “review de novo a challenge to the sufficiency of the evidence supporting a criminal conviction.”
    United States v. Fisher, 
    648 F.3d 442
    , 450 (6th Cir. 2011) (internal quotation marks omitted). “The
    relevant inquiry is whether, viewing the evidence in the light most favorable to the prosecution, any
    rational trier of fact could have found the essential elements of the crime beyond a reasonable
    doubt.” 
    Id. (emphasis in
    original) (internal quotation marks omitted). In addition, the reviewing
    -14-
    No. 10-5753
    United States v. Sperl
    court must “make all reasonable inferences and credibility choices in support of the jury’s verdict.”
    United States v. Hughes, 
    895 F.2d 1135
    , 1140 (6th Cir. 1990).
    After filing its brief in this case, the government submitted citations to supplemental
    authorities under Rule 28(j) of the Federal Rules of Appellate Procedure, arguing that Sperl waived
    her sufficiency-of-evidence objection by failing to raise a motion for a judgment of acquittal at the
    bench trial or to renew a motion for the same at the jury trial. Sperl counters that she did not waive
    the objection during either trial. Because there was sufficient evidence to convict Sperl on all counts,
    however, we do not need to determine whether she has procedurally waived her right to challenge
    the sufficiency.
    1.         Counts 1 and 2
    Sperl first argues that the government did not meet its burden of proving beyond a reasonable
    doubt that she was part of the tax-evasion conspiracy between Michaels, Wolf, and Strong as alleged
    in Count 1. To be guilty of conspiracy, Sperl must have “kn[own] of and adopted the conspiracy’s
    main objective.” See United States v. Bibby, 
    752 F.2d 1116
    , 1124 (6th Cir. 1985). “[D]irect
    evidence of the conspiracy is not necessary. It is enough to present circumstantial evidence [that]
    a reasonable person could interpret as showing participation in a common plan.” 
    Fisher, 648 F.3d at 450
    (internal quotation marks omitted).
    Sperl contends that she did not adopt the main objective of the conspiracy, which was to hide
    InSite’s earnings from the IRS. Rather, she claims that her intent was to earn a substantial fee. This
    argument, however, confuses the purpose of the conspiracy with the personal benefits each
    conspirator expected to gain. Sperl undoubtedly participated in the conspiracy for the $20,000-plus
    -15-
    No. 10-5753
    United States v. Sperl
    fee she expected to earn, as did Michaels. But Sperl would earn the $20,000 only by helping Wolf
    and Strong illegally hide InSite’s earnings from the IRS. Although Sperl may have been motivated
    by her fee, the testimony of Wolf, Strong, and Ancelot established that she “knew of and adopted”
    the main objective of the conspiracy when she took Wolf’s and Strong’s money and tried to move
    it overseas. The evidence was therefore sufficient to convict Sperl on Count 1.
    Under Count 2, Sperl was charged with violating 26 U.S.C. § 7206(2). The elements of
    § 7206(2) are “1) willfully aiding, assisting, procuring, counseling, advising, or causing, 2) the
    preparation or presentation of a federal income tax return, 3) that contains a statement of any material
    matter known by the defendant to be false.” United States v. Searan, 
    259 F.3d 434
    , 443 (6th Cir.
    2001). “This court long ago recognized that the ‘willfully aiding, assisting, procuring, counseling,
    advising, or causing’ language of § 7206(2) effectively incorporates into this statute the theory
    behind accomplice liability.” 
    Id. “Aiding and
    abetting” complicity liability “has two components:
    an act on the part of a defendant [that] contributes to the execution of a crime and the intent to aid
    in its commission.” 
    Id. at 444
    (internal quotation marks omitted).
    Here, Sperl attempted to move $100,000 overseas in order to allow Wolf and Strong to
    illegally deduct that amount from InSite’s income. The fact that she was not the one to prepare or
    sign the tax returns on which Wolf and Strong falsely stated InSite’s income does not preclude her
    conviction under § 7206(2). See 
    id. at 445
    (concluding that the defendant violated § 7206(2) despite
    the fact that another person “prepared and signed most of the returns in question”). Thus, Sperl’s
    conviction on Count 2 also stands.

    No. 10-5753
    United States v. Sperl
    2.        Counts 3, 4, and 5
    Sperl was convicted under Count 3 of conspiring with Ray to illegally understate TLN’s net
    income in its partnership tax returns. She claims that no rational factfinder could have found her
    guilty of this conspiracy because Ray testified at trial that he “never intended to defraud the
    government” at any time. Ray also testified, however, that when TLN’s tax return—prepared by
    Sperl—was filed with the declaration that TLN had paid $240,000 in retirement-plan expenses and
    had only $6,140 in net income, he knew that the return was false.
    When reconciling Ray’s two inconsistent statements in the light most favorable to the
    government, a rational factfinder could have found that Ray was either trying to minimize his
    culpability by not equating a falsified tax return with “defraud[ing] the government,” or was using
    the word “intended” to mean “set out.” Moreover, Ray pleaded guilty to conspiracy to commit tax
    fraud.
    The other inconsistencies that Sperl points to in Ray’s testimony go to the issue of credibility,
    but the district court obviously accepted Ray’s testimony as credible when it convicted Sperl.
    Because Ray’s testimony was not “so internally inconsistent or implausible on its face” as to negate
    it being credited by a reasonable factfinder, we must give considerable deference to the district
    court’s credibility determination. See Anderson v. City of Bessemer City, N.C., 
    470 U.S. 564
    , 575
    (1985) (holding that a district court’s credibility determinations “demand[] even greater deference”
    than its other factual findings “for only the trial judge can be aware of the variations in demeanor and
    tone of voice that bear so heavily on the listener’s understanding of and belief in what is said”).
    -17-
    No. 10-5753
    United States v. Sperl
    Sperl also challenges the sufficiency of the evidence necessary to convict her on Counts 4
    and 5. Both counts charged Sperl with knowing that TLN’s Form 1065 submitted to the IRS was
    false. She asserts that the government’s proof at trial supported her belief that TLN was entitled to
    the $240,000 retirement-plan deduction stated on Form 1065. But the government presented
    evidence that Sperl knew that the Form 1065 tax return was incorrect and that there were no
    legitimate retirement-plan expenses.
    Ray testified that he wrote checks to Sperl totaling $240,000 in November 2000 per her
    direction, and that she gave him the money right back, demonstrating that she knew that Ray had no
    intention of using the money for a retirement plan. In addition, Ray testified that when he told Sperl
    he was applying for a mortgage, she sent him another tax return without the $240,000 retirement-
    plan deduction. A rational trier-of-fact could therefore reasonably find that Sperl knew the
    retirement-plan deduction was false.
    3.        Counts 8 and 9
    Finally, Sperl argues that inconsistencies in Deborah Dotson’s testimony made it impossible
    to rationally find Sperl guilty of assisting in the preparation of fraudulent 2003 and 2004 income-tax
    returns for the Dotsons. Once again, Sperl is asking us to disagree with the district court’s
    determination of a witness’s credibility—something we would do only in egregious circumstances.
    See 
    Anderson, 470 U.S. at 575
    .
    As proof of Dotson’s allegedly inconsistent testimony, Sperl points to Dotson’s assertion that
    Sperl never reviewed the tax returns with Dotson, in contrast to Dotson’s admission that she and her
    husband signed the returns after receiving them from Sperl. This testimony is not in conflict,
    -18-
    No. 10-5753
    United States v. Sperl
    however, because one can receive and sign copies of tax returns without reviewing them with the
    sender.
    Sperl next contends that Dotson’s testimony that her husband was too ill to run a
    maintenance business was inconsistent with her testimony that her husband performed miscellaneous
    maintenance jobs such as detailing and changing the oil of automobiles. A rational factfinder,
    however, could conclude that the ability to take on sporadic mechanical work is much less taxing
    than running one’s own maintenance business. The two statements by Dotson are thus not mutually
    exclusive.
    In addition, Sperl claims that Dotson must be lying about her income because her family of
    four could not have lived on the little that Dotson testified she and her husband brought in during
    2003 and 2004. Sperl therefore contends that there must have been business income. But Dotson’s
    testimony was not inconceivable given that the Dotsons had the aid of free housing, food stamps,
    and Supplemental Security Income for their son. Many families live very frugally, and the fact that
    the Dotsons qualified for food stamps corroborates the fact that they had a very low income.
    Dotson’s testimony was not so inconsistent as to be implausible or to warrant the unusual course of
    reversing the trial court’s credibility determination. We therefore decline to set aside Sperl’s
    convictions on Counts 8 and 9.
    D.        Sentencing enhancements
    Having determined that Sperl’s convictions should stand, we now turn to her sentence. She
    argues that the sentence should be vacated because the district court erroneously applied sentencing
    enhancements for obstruction of justice under U.S.S.G § 3C1.1, sophisticated means under U.S.S.G.
    -19-
    No. 10-5753
    United States v. Sperl
    § 2T1.4(b)(2), and undertaking a leadership role under U.S.S.G. § 3B1.1(c). A district court must
    find that a preponderence of the evidence supports a sentencing enhancement before imposing it.
    United States v. Dupree, 
    323 F.3d 480
    , 491 (6th Cir. 2003). We review that finding under the clear-
    error standard. United States v. Angel, 
    355 F.3d 462
    , 475 (6th Cir. 2004).
    1.        Obstruction of justice
    Sperl first argues that the obstruction-of-justice enhancement was improper because the
    government offered no evidence that her alleged instruction to Wolf—that he should tell the IRS that
    she was helping InSite invest in coffee beans or textiles—impeded any investigation. The
    obstruction-of-justice enhancement applies, however, where a defendant “willfully obstructed or
    impeded, or attempted to obstruct or impede, the administration of justice with respect to the
    investigation . . . of the instant offense of conviction . . . .” U.S.S.G § 3C1.1 (emphasis added). This
    includes “unlawfully influencing a co-defendant, witness, or juror, directly or indirectly, or
    attempting to do so.” 
    Id., cmt. n.4(a)
    (emphasis added). The enhancement may therefore be imposed
    even if the investigation was not actually impeded by Sperl’s attempt to influence Wolf.
    Sperl cites United States v. Williams, 
    952 F.2d 1504
    , 1516 (6th Cir. 1991), for the principle
    that a false statement given by the defendant to investigators that “fooled no one” is not enough to
    impose the obstruction-of-justice enhancement. But this principle is inapplicable where the
    defendant is accused of trying to influence someone else to lie to authorities. Under this latter
    scenario, all that is necessary is an attempt to do so; whether the attempt was successful is irrelevant.
    United States v. Grigsby, 338 F. App’x 514, 517 (6th Cir. 2009) (concluding that there was
    -20-
    No. 10-5753
    United States v. Sperl
    “sufficient foundation to support [an obstruction-of-justice] enhancement” because the witness
    “testified that Grigsby attempted to influence [the witness’s] testimony” (emphasis added)).
    In regard to Counts 3, 4, and 5, Sperl also argues that there was no proof that she tried to
    coach Ray about what to tell IRS agents. But Ray testified that Sperl instructed him to say that they
    were “passing money back and forth, [they] were doing loans,” which Ray acknowledged was a lie.
    Sperl’s argument is thus without merit.
    In sum, evidence was presented to show that Sperl attempted to have both Wolf and Ray lie
    to the IRS. The district court’s decision to impose the obstruction-of-justice enhancement was
    therefore not clearly erroneous.
    2.        Sophisticated means
    Sperl’s objection to the imposition of the sophisticated-means enhancement similarly fails.
    She claims that the means that she allegedly used to commit these offense were not “especially
    complex or especially intricate,” as required by the U.S. Sentencing Guidelines for the enhancement
    to apply. See U.S.S.G. § 2T1.4, cmt. n.3. The Guidelines, however, specifically state that the use
    of “offshore financial accounts ordinarily indicates sophisticated means.” 
    Id. Because testimony
    was presented to show that Sperl attempted to move money offshore and also attempted to hide
    money through a series of loans and false invoices, the district court did not clearly err in concluding
    that the sophisticated-means enhancement applied.
    3.        Leadership role
    In the last challenge to her sentence, Sperl contends that the district court erred in applying
    the leadership-role enhancement. Under U.S.S.G. § 3B1.1(c), if Sperl “was an organizer, leader,
    -21-
    No. 10-5753
    United States v. Sperl
    manager, or supervisor in any criminal activity,” she is subject to a 2-point Guidelines enhancement.
    Factors for determining whether she undertook such a role include “the exercise of decision making
    authority, the nature of participation in the commission of the offense, . . . the degree of participation
    in planning or organizing the offense, . . . and the degree of control and authority exercised over
    others.” U.S.S.G. § 3B1.1, cmt. n.4.
    The testimony with regard to Counts 1 through 5 provided sufficient proof that Sperl took
    control and possession of the money that was to be hidden from the IRS and devised methods to
    move it through various accounts so as to make it untraceable. For Counts 1 and 2, Michaels
    arguably played the greater leadership role, but this fact does not undermine Sperl’s own leadership
    role. See 
    id. (noting that
    more than one person can be a leader or organizer of a conspiracy). And
    for Counts 3, 4, and 5, Sperl clearly managed the scheme to hide TLN’s assets and decided how the
    transactions between her and Ray would occur. This sentencing enhancement was therefore
    correctly applied.
    4.        Below the Guidelines sentence
    Despite Sperl’s objections to the various sentencing enhancements, we note that she makes
    no comment about the fact that her 36-month sentence is less than half of the low end of the
    applicable Guidelines range of 78 to 97 months of imprisonment. In fact, the advisory Guidelines
    range without any of the enhancements (i.e., at an offense level of 20 and a criminal history
    category I) would be 33 to 41 months. U.S.S.G. Ch. 5, Pt. A, sentencing table (2009). Thus, even
    without any of the enhancements, Sperl could have received a within-Guidelines sentence
    significantly longer than 36 months. Sperl should therefore consider herself fortunate that the district
    -22-
    No. 10-5753
    United States v. Sperl
    court varied downward from the applicable Guidelines range, especially because a within-Guidelines
    sentence is considered presumptively reasonable on appeal. See United States v. Reilly, 
    662 F.3d 754
    , 760 (2011) (noting that “sentences that fall within the applicable Guidelines range are rebuttably
    presumed to be reasonable” (brackets and internal quotation marks omitted)).
    III. CONCLUSION
    For all of the reasons set forth above, we AFFIRM the judgment of the district court.
