- The general statute of limitations for the IRS to assess a tax deficiency is three years. Under which of the following circumstances is the statute of limitations extended to six years?
Answer: The taxpayer omits from gross income an amount that exceeds 25% of the gross income stated on the return.
Under Section 6501(e), the statute of limitations for assessment is extended to six years when a taxpayer omits from gross income an amount that is more than 25% of the gross income reported on the return. This is known as the substantial omission rule. Answer A is incorrect because a missing schedule, while potentially a processing issue, does not automatically extend the statute to six years. Answer B is incorrect because a valuation understatement alone does not trigger the six-year period; it may trigger penalties, but the six-year rule applies to gross income omissions. Answer C is incorrect because a disallowed deduction affects taxable income but does not represent an omission of gross income under Section 6501(e).
- A taxpayer files a fraudulent tax return. What statute of limitations applies to the IRS's ability to assess the deficiency attributable to fraud?
Answer: There is no statute of limitations; the IRS may assess the deficiency at any time.
Under Section 6501(c)(1), in the case of a false or fraudulent return filed with intent to evade tax, there is no statute of limitations on assessment. The IRS may assess the deficiency at any time. This exception also applies when a taxpayer willfully attempts to evade tax or when no return is filed at all (Section 6501(c)(3)). Answer A (six years) is the extended statute for substantial omissions of gross income, not for fraud. Answer C (three years from discovery) is not a statutory provision; the Code provides no limitations period for fraud. Answer D (ten years) is the period for collection after assessment, not for the assessment of a deficiency on a fraudulent return.
- Under the IRS examination process, which of the following best describes the purpose of issuing a Revenue Agent's Report (RAR)?
Answer: The RAR documents the findings of the examination, including proposed adjustments to the taxpayer's return, and serves as the basis for the 30-day letter sent to the taxpayer.
A Revenue Agent's Report (RAR) is the document prepared by the examining revenue agent at the conclusion of an audit. It details the agent's proposed adjustments to the taxpayer's return with explanations of the legal basis for each change. The RAR accompanies the 30-day letter (the examination report) sent to the taxpayer. Answer B is incorrect because the RAR is an administrative document, not a court filing. Answer C is incorrect because the RAR precedes the formal assessment; assessment occurs after the taxpayer's opportunity to respond to the 30-day letter and after the issuance and expiration of the 90-day letter. Answer D is incorrect because the RAR is not a penalty notice; it is a comprehensive examination findings document.
- A taxpayer files a tax return on January 20 (before the April 15 due date). The IRS has how long to assess a deficiency under the standard three-year statute of limitations?
Answer: Three years from April 15, the due date of the return, because the statute runs from the later of the filing date or the due date.
Under Section 6501(b)(1), a return filed before its due date is treated as filed on the due date for purposes of the statute of limitations. Therefore, even though the taxpayer filed on January 20, the three-year statute of limitations runs from April 15 (the due date), giving the IRS until April 15 of the third year after the original due date. Answer A is incorrect because early filing does not start the limitations clock earlier than the due date. Answer C is incorrect for the same reason. Answer D is incorrect because the statute runs from the filing date (or due date if earlier), not from the IRS processing date.
- What is the general period within which a taxpayer must file a claim for refund of an overpayment of federal income tax?
Answer: The later of three years from the date the return was filed or two years from the date the tax was paid.
Under Section 6511(a), a claim for refund must be filed within the later of (1) three years from the time the return was filed, or (2) two years from the time the tax was paid. If no return was filed, the period is two years from the date of payment. This means a taxpayer who paid tax late and then discovered an overpayment has at least two years from payment to file a claim. Answer A (one year) is too short and not a statutory period under Section 6511. Answer B (three years from due date only) ignores the two-year-from-payment alternative. Answer C (five years from payment) is not a standard refund claim period under the Code.
- A taxpayer who is not satisfied with the IRS Appeals Office decision wishes to litigate but has not yet paid the disputed tax. Which federal court has jurisdiction to hear the case without requiring prepayment of the tax?
Answer: U.S. Tax Court
The U.S. Tax Court is the only federal court where a taxpayer may challenge a deficiency without first paying the disputed tax. The taxpayer must file a petition within 90 days of the notice of deficiency. Both the U.S. District Court and the U.S. Court of Federal Claims require full payment of the tax before the taxpayer files a refund suit. Answer D is incorrect because the U.S. Bankruptcy Court does not have general income tax deficiency jurisdiction.
- A taxpayer signs a Form 872 (Consent to Extend the Time to Assess Tax). What is the effect of this consent?
Answer: The statute of limitations for assessment is extended to the date specified in the agreement, preserving the IRS's ability to assess beyond the standard three-year period.
Form 872 is a consent agreement between the taxpayer and the IRS that extends the statute of limitations for assessment to a specific date. This gives both parties additional time to resolve issues without requiring the IRS to prematurely assess a deficiency. The extension is binding on both parties. Answer B is incorrect because signing Form 872 does not waive appeal rights; it only extends the assessment period. Answer C is incorrect because Form 872 extends the statute to a specific agreed-upon date, not automatically by a fixed period. Answer D is incorrect because the consent is binding on both the IRS and the taxpayer once signed; neither party may unilaterally revoke it.
- A taxpayer's return is selected for audit and the IRS asserts a deficiency of $15,000. The taxpayer qualifies to use the Small Tax Case (S case) procedure in the U.S. Tax Court. Which of the following correctly describes an S case?
Answer: S cases are available for disputes involving deficiencies of $50,000 or less per year and the decision is final with no right of appeal.
Under Section 7463, the Small Tax Case (S case) procedure is available when the amount in dispute does not exceed $50,000 for any single tax year. S cases are conducted informally with relaxed evidentiary rules, but the decisions are final and not appealable by either party. This provides a faster, less expensive forum for smaller disputes. Answer C is correct. Answer A is incorrect because it states the wrong threshold ($25,000) and incorrectly states that S case decisions are appealable. Answer B is incorrect because S case decisions are not appealable by either the taxpayer or the IRS; a taxpayer who wants the right to appeal must proceed under regular Tax Court procedures rather than the S case election. Answer D is incorrect because while S case proceedings are informal, the Tax Court applies legal standards and the Internal Revenue Code, not simply equitable discretion.
- Which of the following events will toll (suspend) the running of the statute of limitations for assessment of a tax deficiency?
Answer: The taxpayer files a petition in the U.S. Tax Court after receiving a notice of deficiency.
Under Section 6503(a), the statute of limitations for assessment is suspended (tolled) during the period when the IRS is prohibited from making an assessment. When a taxpayer petitions the Tax Court after receiving a notice of deficiency, the IRS is prohibited from assessing the deficiency until the Tax Court decision becomes final, plus 60 days. This tolling prevents the statute from expiring during the litigation. Answer A is incorrect because filing an extension of time to file merely moves the return due date and extends the statute accordingly; it does not toll a running period. Answer B is incorrect because opening an audit does not by itself toll the statute; the IRS must take action within the period. Answer C is incorrect because an amended return does not toll the statute of limitations; it may restart the period for certain items if it constitutes a substantial change.
- The IRS assessed a tax deficiency and the taxpayer paid the full amount. The taxpayer subsequently believes the assessment was incorrect and wants a refund. Which of the following is the correct procedure?
Answer: File an administrative claim for refund with the IRS; if disallowed or not acted upon within 6 months, the taxpayer may sue in U.S. District Court or the Court of Federal Claims.
Once the tax has been paid, the taxpayer must follow the refund route: file an administrative claim for refund (typically on Form 1040X or Form 843). If the claim is denied or the IRS fails to act within six months, the taxpayer may file suit in U.S. District Court or the U.S. Court of Federal Claims. Answer A is incorrect because Tax Court jurisdiction in deficiency cases requires that the tax not yet be assessed; once paid, the taxpayer cannot use Tax Court for a pre-payment challenge on the same issue. Answer B is incorrect because the payment does not automatically trigger an Appeals conference and does not toll the statute in that way. Answer C is incorrect because an amended return alone does not generate an automatic refund; a formal refund claim and IRS determination are required.
- A taxpayer received an IRS notice stating that an audit will be conducted as a Taxpayer Compliance Measurement Program (TCMP) examination. How does a TCMP examination differ from a standard audit?
Answer: A TCMP examination is a comprehensive line-by-line audit of every item on the return, used by the IRS to gather statistical data on compliance, whereas a standard audit typically focuses on specific items or issues.
A TCMP (now often referred to as the National Research Program) examination is an intensive, line-by-line audit of every item on the return. Its primary purpose is to gather statistical data to update the DIF scoring system and measure overall taxpayer compliance. These audits are more burdensome than targeted examinations. Answer B is incorrect because TCMP examinations are more comprehensive, not less burdensome. Answer C is incorrect because TCMP examinations may involve in-person meetings, document requests, and field visits. Answer D is incorrect because the IRS may propose deficiencies based on TCMP findings; the data-gathering purpose does not preclude adjustments.
- A taxpayer receives a 30-day letter from the IRS following an examination. Which of the following correctly describes the taxpayer's options upon receipt of the 30-day letter?
Answer: The taxpayer may accept the proposed changes, request an Appeals Office conference, or do nothing and wait for a statutory notice of deficiency.
The 30-day letter (also called the examination report) notifies the taxpayer of proposed changes following an audit. The taxpayer has three main options: (1) agree and sign the consent to assessment, (2) request a conference with the IRS Office of Appeals within 30 days, or (3) do nothing, in which case the IRS will issue a statutory notice of deficiency (the 90-day letter). Answer B is incorrect because failure to respond within 30 days does not make the assessment final; the taxpayer will receive a 90-day letter. Answer C is incorrect because Tax Court petitions are filed in response to the 90-day letter, not the 30-day letter. Answer D is incorrect because an administrative appeal to the Appeals Office is available after the 30-day letter.
- After receiving a statutory notice of deficiency (90-day letter), a taxpayer who disagrees with the IRS determination and wants to contest the deficiency without first paying the tax should file a petition in which court?
Answer: U.S. Tax Court
The U.S. Tax Court is the only federal forum in which a taxpayer may contest a deficiency without first paying the disputed tax. The taxpayer must file a petition within 90 days of the notice of deficiency (150 days if the notice is addressed to a person outside the United States). Answer A is incorrect because the U.S. District Court requires payment of the full deficiency before filing a refund suit. Answer C is incorrect because the U.S. Court of Federal Claims also requires full payment before jurisdiction attaches. Answer D is incorrect because the U.S. Court of Appeals is an appellate court and is not a trial-level forum for tax disputes.
- Which of the following accurately describes the IRS field audit?
Answer: An examination in which an IRS revenue agent visits the taxpayer's home or place of business to examine books, records, and other documents.
A field audit is conducted by an IRS revenue agent at the taxpayer's home, place of business, or the office of the taxpayer's representative. Field audits are typically used for more complex returns, including businesses, and involve direct examination of books, records, and supporting documentation. Answer A describes a correspondence audit. Answer C describes an office audit. Answer D is incorrect because field audits are not limited to corporations above a specific gross receipts threshold; they are used for any examination that the IRS determines warrants on-site review.
- Which of the following best describes the IRS's use of a summons during an examination?
Answer: A summons may be issued to require a person to appear, produce documents, or give testimony relevant to an examination, and may be directed to the taxpayer or third parties.
Under Section 7602, the IRS has broad authority to issue administrative summonses requiring any person to appear and testify, produce documents, or provide other information relevant to a tax examination or investigation. Summonses may be directed to the taxpayer directly or to third parties, including banks and employers. Answer A is incorrect because the IRS routinely issues summonses to third-party recordkeepers. Answer B is incorrect in that while the IRS generally must notify taxpayers of third-party summonses under Section 7609, it is not always required to notify before issuance in all circumstances. Answer C is incorrect because summonses may be challenged in federal court through a motion to quash.
- The IRS uses the Discriminant Function System (DIF) score as part of its return selection process. Which of the following best describes the DIF score?
Answer: A computer-generated score that compares items on a return to statistical norms to identify returns with the highest potential for unreported income or erroneous deductions.
The Discriminant Function System (DIF) is a computer-based scoring system the IRS uses to identify individual returns with the greatest audit potential. It compares each line item to statistical norms for similar taxpayers and assigns a score based on how much items deviate from those norms. Higher DIF scores indicate greater potential for error or unreported income. Answer A is incorrect because the DIF score is not based on a taxpayer's audit history but on current-year return characteristics. Answer C is incorrect because the DIF score is not a simple threshold test for individual deductions. Answer D is incorrect because the DIF system is used primarily for individual returns, not exclusively for corporate returns.
- Which of the following accurately describes the process for appealing a U.S. Tax Court decision?
Answer: Tax Court decisions may generally be appealed to the U.S. Court of Appeals for the circuit in which the taxpayer resides, except for S case decisions which are not appealable.
Tax Court decisions may be appealed by either the taxpayer or the IRS to the U.S. Court of Appeals for the circuit where the taxpayer resided at the time the petition was filed. From the Court of Appeals, further review by the U.S. Supreme Court is possible via certiorari. However, Small Tax Case (S case) decisions under Section 7463 are final and not appealable by either party. Answer A is incorrect because appeals go to the circuit court level first, not directly to the Supreme Court. Answer B is incorrect because regular Tax Court decisions are appealable. Answer D is incorrect because either the taxpayer or the IRS may appeal a Tax Court decision.
- A taxpayer who disagrees with an IRS Appeals Office decision and wants to litigate in a forum where a jury trial is available should file suit in which court?
Answer: U.S. District Court
The U.S. District Court is the only federal forum where a taxpayer may request a jury trial in a tax dispute. To sue in District Court, the taxpayer must first pay the full amount of the disputed tax and then file a refund suit. Answer A is incorrect because the U.S. Tax Court does not provide jury trials; cases are decided by Tax Court judges. Answer B is incorrect because the U.S. Court of Federal Claims also does not provide jury trials. Answer D is incorrect because the U.S. Court of International Trade handles customs and trade matters, not income tax disputes.
- What is the general statute of limitations for the IRS to collect a tax that has already been assessed?
Answer: 10 years from the date of assessment.
Under Section 6502, the IRS generally has 10 years from the date of assessment to collect a tax by levy or court proceeding. This is distinct from the statute of limitations for assessment (3 years in most cases). After the 10-year collection period expires, the IRS's ability to collect the assessed tax is barred. Answer A (3 years) is the statute for assessment, not collection. Answer B (6 years) is the extended assessment period for substantial omissions, not the collection period. Answer C is incorrect because there is a 10-year limitations period on collection.
- A taxpayer timely files a return on April 15. The IRS mails a notice of deficiency on April 10 of the fourth year after filing (three years and 361 days after the return was filed). Has the statute of limitations for assessment expired?
Answer: No, the notice was mailed within the three-year statute of limitations period, so the assessment is timely.
The three-year statute of limitations for assessment under Section 6501(a) runs from the later of the date the return was filed or the return due date. The statute expires three years after the filing date, measured to the same calendar day three years later. A return filed April 15, Year 1 has a statute that expires April 15, Year 4. A notice mailed April 10 of Year 4 is within the three-year window and is therefore timely. Answer B is incorrect because the statute expires on the third anniversary date, not before it; mailing before that date is timely. Answer C is incorrect for the same reason; April 10 of the fourth year is before the April 15 expiration. Answer D is incorrect because filing on the due date is the standard scenario and does not independently extend the statute.
