Most tax practitioners work in civil tax: examinations, Appeals, collection, and the administrative processes that follow a return. But civil tax and criminal tax can arise from exactly the same facts. A Schedule C with fabricated deductions triggers not only a civil deficiency but potentially an IRC 7201 evasion charge. Unreported cash income that a client "forgot to mention" carries not only the civil fraud penalty but potentially a federal felony prosecution. And a preparer who helps structure a false return faces IRC 7206(2) criminal exposure alongside any Circular 230 sanction. This guide covers the three central criminal tax statutes -- IRC 7201, 7202, and 7206 -- plus the misdemeanor companion under IRC 7203, the willfulness standard under Cheek, the six-year criminal statute of limitations under IRC 6531, and the practical obligations of a civil practitioner when criminal exposure is present.
This guide is not a criminal defense manual. It is written for civil tax practitioners -- enrolled agents, CPAs, and tax attorneys -- who need to recognize when a client situation has crossed or may cross the civil/criminal line, understand the statutory framework well enough to have an intelligent conversation with criminal defense counsel, and fulfill their professional obligations when criminal exposure is present. For specific client situations, engage qualified criminal defense counsel. Verify all statutory citations, penalty ranges, and procedural details at IRS.gov and the Department of Justice Tax Division website before advising any client.
The Civil/Criminal Boundary in Federal Tax Enforcement
The IRS has two enforcement tracks: civil and criminal. Civil enforcement is conducted by Revenue Agents and Revenue Officers; it results in assessments, penalties, and collection actions. Criminal enforcement is conducted by IRS Criminal Investigation (IRS-CI) special agents; it results in federal prosecution in district court, not in the Tax Court.
Civil and criminal cases are procedurally separate and require different standards of proof. The IRS must prove a civil fraud penalty by clear and convincing evidence. A federal criminal tax conviction requires proof beyond a reasonable doubt on all elements of the offense. The higher criminal burden means prosecutors are selective about which cases they bring. Cases with clear evidence of willful conduct, material understatements, and affirmative acts of concealment are the targets; negligence and inadvertence cases are handled civilly.
The key gate between civil and criminal treatment is the referral. A Revenue Agent who encounters potential fraud during an examination refers the case to IRS-CI using Form 2797 (Referral Report of Potential Criminal Violations). Once IRS-CI accepts a referral, the civil examination is typically placed in suspense, meaning it stops while the criminal investigation proceeds. The Revenue Agent who made the referral has no further contact with the taxpayer on the civil side until the criminal matter is resolved.
Civil practitioners need to be aware of the referral mechanism because a client may not know one has been made. The first visible sign is often an unexplained halt in a civil examination, followed eventually by contact from a special agent. By the time a special agent makes contact, the investigation is already underway. The time to coordinate with criminal defense counsel is before that contact, if the civil facts suggest potential criminal exposure.
IRC 7201: Attempted Tax Evasion
IRC 7201 makes it a federal felony to willfully attempt to evade or defeat any tax imposed by the Internal Revenue Code or the payment of such tax. A conviction requires the government to prove three elements beyond a reasonable doubt:
- Willfulness: The defendant voluntarily and intentionally violated a known legal duty. A good-faith mistake is not willful.
- Existence of a tax deficiency: The defendant actually owed more tax than was reported or paid. No deficiency, no IRC 7201 charge.
- An affirmative act of evasion: The defendant took a deliberate step to evade or defeat the tax or its payment. This is the element that distinguishes evasion from mere failure to file or pay.
The Affirmative Act Requirement
The affirmative act requirement is what separates IRC 7201 evasion from the lesser offense under IRC 7203 (willful failure to file or pay, a misdemeanor). The act must be an active step toward evasion, not just the passive failure to file or pay. Courts have found affirmative acts to include: filing a return that understates income or overstates deductions; routing income through nominee entities or accounts; maintaining false business records; making false oral or written statements to IRS agents; structuring cash transactions to avoid Bank Secrecy Act reporting thresholds; and transferring assets to third parties to place them beyond the IRS's reach.
Prosecutors typically present a pattern of affirmative acts rather than a single act. In a cash-underreporting case, for example, the government may show that the taxpayer received cash payments, did not deposit them through normal business channels, maintained a second set of records, and then filed a return showing only the deposited amounts. Each step in that pattern is an affirmative act.
Badges of Fraud Versus Negligence
Civil practitioners evaluating whether a client situation carries criminal exposure should watch for what courts call "badges of fraud": patterns that distinguish willful concealment from careless record-keeping. Common badges include substantial unexplained cash deposits, duplicate books or altered records, failure to report consistently across multiple years, hiding assets in family members' names, and unusual or fictitious business deductions that bear no relationship to the client's actual activity. No single badge is conclusive, but multiple badges appearing together tend to characterize the cases that IRS-CI pursues.
Caution: A TFRP Civil Assessment and an IRC 7202 Criminal Prosecution Can Arise From the Same Payroll Tax Failure
The Trust Fund Recovery Penalty under IRC 6672 and the criminal offense under IRC 7202 address the same underlying conduct: willful failure to collect or pay over withheld payroll taxes. A civil TFRP assessment does not bar a subsequent criminal prosecution for the same quarters. Practitioners representing clients in TFRP proceedings should evaluate whether the same willfulness evidence that supports the TFRP could also support a criminal referral to IRS-CI. If criminal exposure appears plausible, recommend criminal defense counsel before making any admissions on the willfulness question in the civil TFRP interview.
IRC 7202: Willful Failure to Collect or Pay Over Tax
IRC 7202 targets the criminal dimension of payroll tax noncompliance. It makes it a felony for any person who is required to collect, account for, and pay over any tax imposed by the Internal Revenue Code to willfully fail to do so. The statute applies primarily to persons who withhold income and FICA taxes from employees' wages but then fail to remit those withheld amounts to the IRS.
The elements of IRC 7202 are: (1) willfulness, (2) a duty to collect, account for, or pay over the tax, and (3) willful failure to perform that duty. Unlike IRC 7201, there is no separate affirmative act requirement: the willful failure itself is the offense.
The relationship between the civil Trust Fund Recovery Penalty under IRC 6672 and the criminal offense under IRC 7202 is significant. Both arise from the same conduct and the same employer-employee context. The civil TFRP requires proof by a preponderance of evidence that the responsible person willfully failed to remit; the criminal charge requires proof beyond a reasonable doubt of the same willful failure. IRS-CI typically investigates IRC 7202 cases involving repeated quarters of non-remittance, large dollar amounts, and circumstances suggesting the funds were diverted for personal or business purposes rather than simply a cash-flow problem.
See the Trust Fund Recovery Penalty Practitioner Guide for the civil TFRP framework under IRC 6672, including the responsible-person determination, the willfulness standard in the civil context, and the Form 4180 interview procedure.
IRC 7206: Fraud and False Statements
IRC 7206 contains two key subsections for civil tax practitioners. Both are federal felonies. Both require willfulness. Both can reach preparers directly, not just taxpayers.
IRC 7206(1): Willfully Making and Subscribing a False Document
IRC 7206(1) makes it a felony to willfully make and subscribe any return, statement, or other document that contains a written declaration that it is made under the penalties of perjury, where the person does not believe that document to be true and correct as to every material matter. For taxpayers, this is the false-return charge. For preparers who sign a return as the paid preparer, it is direct criminal exposure. A preparer who signs a return containing knowingly false information has subscribed to a document under penalties of perjury and may be charged under IRC 7206(1).
IRC 7206(2): Aiding or Assisting in the Preparation of a False Document
IRC 7206(2) is the preparer's primary criminal exposure provision. It makes it a felony for any person who willfully aids or assists in, procures, counsels, or advises the preparation or presentation of a return, affidavit, claim, or other document that is fraudulent or false as to any material matter. The critical point: the person charged under IRC 7206(2) does not have to sign the document, and does not have to be the taxpayer. A preparer who knowingly assists a client in claiming fictitious deductions, structures a transaction to generate false losses, or coaches a client to omit income faces IRC 7206(2) exposure even if the preparer never puts their name on the return.
Warning: IRC 7206(2) Is a Federal Felony for Preparers Who Aid in Filing False Returns -- Circular 230 Sanctions Are a Separate and Additional Consequence
A preparer charged and convicted under IRC 7206(2) faces federal felony prosecution in addition to, not instead of, Circular 230 discipline. A felony conviction is an independent ground for disbarment from practice before the IRS under Circular 230 Section 10.52. IRS-CI has pursued IRC 7206(2) charges against preparers who assisted clients in filing fraudulent Employee Retention Credit claims, inflated deduction schemes, and false offshore income arrangements. The IRS does not require a civil preparer penalty assessment under IRC 6694 or 6695 before referring a preparer to IRS-CI. If you prepared a return that you now believe may contain a material false item, consult criminal defense counsel before taking any action.
IRC 7203: Willful Failure to File, Pay, or Supply (Misdemeanor)
IRC 7203 is a Class A misdemeanor that makes it unlawful for any person who is required to pay any estimated tax, make a return, keep any records, or supply any required information to willfully fail to do so. It is the lightest of the criminal tax charges and can be charged as an alternative when the elements of IRC 7201 evasion cannot all be proven. The willful failure to file a return, pay tax when due, maintain required records, or provide required information each constitutes a separate offense under IRC 7203. Verify maximum penalties under current statute at IRS.gov before advising.
Quick-Reference: The Criminal Tax Statutes
The table below summarizes the key features of each offense. Verify current statutory text, maximum penalties, and prosecution standards at IRS.gov and the DOJ Tax Division website before advising any client.
| Statute | Offense | Type | Key Elements | Max Imprisonment | SOL |
|---|---|---|---|---|---|
| IRC 7201 | Attempted tax evasion | Felony | Willfulness + tax deficiency + affirmative act of evasion | 5 years | 6 years (IRC 6531) |
| IRC 7202 | Willful failure to collect or pay over tax | Felony | Willfulness + duty to collect or pay over + failure to do so | 5 years | 6 years (IRC 6531) |
| IRC 7206(1) | Willfully making and subscribing a false document | Felony | Willfulness + subscription of false document under penalties of perjury | 3 years | 6 years (IRC 6531) |
| IRC 7206(2) | Aiding or assisting preparation of a false document | Felony | Willfulness + aiding, assisting, or procuring a false document | 3 years | 6 years (IRC 6531) |
| IRC 7203 | Willful failure to file, pay, or supply information | Misdemeanor | Willfulness + specific failure (file, pay, or supply) | 1 year | 6 years (IRC 6531) |
Maximum fines are governed by 18 USC 3571 and may exceed figures stated in the IRC statute text. Verify current fine maximums at IRS.gov and DOJ Tax Division before advising.
The Willfulness Standard: Cheek and the Good-Faith Defense
Willfulness is a common element of every criminal tax offense. In Cheek v. United States, 498 U.S. 192 (1991), the Supreme Court held that willfulness in the criminal tax context means a voluntary, intentional violation of a known legal duty. The Court further held that a defendant who sincerely believes in good faith that the law does not require what the government charges does not have the willfulness necessary for a criminal conviction -- even if that belief is objectively unreasonable.
The Cheek standard reflects the Supreme Court's recognition that tax law is complex and that the risk of convicting someone for a genuine mistake is real. But the practical limits of the Cheek defense are significant. Willfulness is a question of fact for the jury. The jury determines whether the defendant's claimed belief was genuine. A factfinder will consider the defendant's education, business sophistication, access to counsel, the size of the understatement, the length of time it persisted, and whether the defendant's conduct resembled that of a person who genuinely did not know or someone who was concealing.
Note: Cheek Requires a Sincere Belief, Not Just a Stated Belief -- and Tax-Defier Arguments Are Not a Defense
The Supreme Court in Cheek made clear that a claimed belief that wages are not taxable or that the tax law is unconstitutional does not qualify for the good-faith defense, because those positions have been repeatedly and definitively rejected by the courts. Reliance on such a position is not a sincere good-faith belief; it is a known-rejected legal argument. Preparers whose clients hold tax-defier views should be aware that advising or assisting in filing returns based on those positions carries substantial IRC 7206(2) exposure. A "good faith" defense is not available for positions that have been conclusively settled in court.
The Sansone Distinction: Evasion vs. Willful Failure to Pay
Sansone v. United States, 380 U.S. 343 (1965), addressed the relationship between IRC 7201 (attempted evasion) and IRC 7203 (willful failure to pay). The Court clarified that IRC 7201 requires proof of an affirmative act, while IRC 7203 requires only a willful failure. A defendant who owed taxes, knew they owed them, and failed to pay (without any affirmative act of concealment) is a IRC 7203 defendant, not necessarily a IRC 7201 defendant. This distinction matters both for charging decisions and for defense strategy: a preparer representing a client facing 7201 charges should examine whether all three elements are genuinely present or whether the facts support only a 7203 misdemeanor.
Statute of Limitations: IRC 6531 and the Six-Year Criminal SOL
IRC 6531 sets the statute of limitations for criminal tax prosecutions. For the offenses covered by IRC 6531(2) -- which includes IRC 7201, 7202, 7206, and related offenses -- the limitation period is six years from the date the offense was committed. For return-based offenses like IRC 7206(1) (subscribing a false return), the six years generally runs from the date the false return was filed.
The criminal six-year SOL is twice the standard three-year civil assessment SOL under IRC 6501. A civil examination for a given tax year may be completely barred by the civil SOL while a criminal prosecution for the same year is still timely. Practitioners who assume that the end of the civil SOL period closes the books on a matter should be aware that the criminal SOL runs independently.
The criminal SOL is tolled (suspended) when a grand jury indictment or criminal information is filed against the defendant. Once the indictment is filed, the SOL stops running. The government does not need to bring the matter to trial before the SOL runs -- it only needs to indict. Verify current IRC 6531 text and any applicable tolling provisions at IRS.gov and the DOJ Tax Division before advising.
IRS Criminal Investigation: How Investigations Begin and Develop
IRS-CI is the criminal investigation arm of the IRS. Special agents are federal law enforcement officers with arrest and search warrant authority; they are not Revenue Agents. IRS-CI investigations can begin from multiple sources: a civil examination referral via Form 2797, a confidential informant tip, a report from a financial institution (Suspicious Activity Report under the Bank Secrecy Act), a whistleblower submission, or an IRS-CI proactive investigation of a particular industry or scheme type (such as ERC promoters or offshore tax evasion).
When IRS-CI opens an investigation, it typically conducts a preliminary investigation first before committing to a full investigation. During the preliminary phase, special agents gather publicly available information, financial institution records, and records from third parties. The subject of the investigation may not know it exists at this stage. The first contact is often a visit to the subject's home or business, or a phone call from a special agent, often accompanied by leaving a business card. This initial contact is the signal to refer to criminal defense counsel immediately.
If IRS-CI recommends prosecution, the case is referred to the DOJ Tax Division, which decides whether to authorize prosecution. If authorized, the DOJ Tax Division works with the U.S. Attorney's Office to present the case to a grand jury for indictment, or to proceed by criminal information if the defendant agrees to waive indictment (typically in the context of a plea agreement).
Warning: When an IRS-CI Special Agent Contacts a Client, Do Not Allow the Client to Answer Questions Without Criminal Defense Counsel Present -- and Do Not Make Representations on the Client's Behalf
A civil tax practitioner's Form 2848 power of attorney does not extend to IRS-CI criminal matters. If a special agent contacts your client, your immediate actions should be: advise the client in writing not to speak with the agent or provide any documents without first retaining criminal defense counsel; decline to make any substantive representations to IRS-CI on the client's behalf; and assist the client in identifying qualified federal criminal defense counsel with criminal tax experience. Do not call the special agent to "explain" the situation or offer voluntary document production. Anything said to IRS-CI -- by the client or by you -- can be used against the client. The time to preserve the client's rights is before any voluntary cooperation, not after.
Parallel Civil and Criminal Proceedings
Civil tax examinations and criminal tax investigations can and do run simultaneously or sequentially. The civil examination may precede a criminal referral, or a criminal investigation may begin while a civil examination is still open. Understanding how the two tracks interact is critical for civil practitioners who want to protect their clients' interests.
Statements Made During Civil Examination
Statements made to Revenue Agents during a civil examination are not protected from use in a subsequent criminal prosecution. If a client provides a written response to an IDR, makes statements in an examination interview, or produces documents voluntarily, that material is available to IRS-CI if a criminal referral is made. The civil practitioner should be aware that admissions of fact made during a civil examination may become evidence in a criminal case.
The Fifth Amendment in Civil Tax Proceedings
A client facing potential criminal exposure has a Fifth Amendment right against self-incrimination that applies in IRS civil proceedings. A taxpayer may assert the Fifth Amendment right in response to IRS questions during a civil examination. However, invoking the Fifth Amendment in a civil proceeding carries costs: the IRS may draw an adverse inference against the taxpayer in the civil case, and the assertion signals that the client has Fifth Amendment concerns. The decision whether to invoke the Fifth Amendment in a civil proceeding is a judgment call that requires both civil and criminal defense counsel to weigh in together.
Caution: Do Not Make the Fifth Amendment Decision for Your Client -- Criminal Defense Counsel Must Be Part of That Conversation
Advising a client to invoke the Fifth Amendment in a civil IRS proceeding without involving criminal defense counsel is outside the civil practitioner's lane and can harm the client's overall position. The decision involves weighing the civil consequences of invoking (adverse inference in the civil case), the criminal protection gained (statements not usable against the client), and the strategic implications for any subsequent criminal matter. That weighing requires coordinated advice from both counsel. The civil practitioner's role when criminal exposure is suspected is to ensure criminal defense counsel is retained and to defer on Fifth Amendment strategy to that counsel.
When to Refer to Criminal Defense Counsel
The civil practitioner's most important judgment call in a case with potential criminal exposure is when to refer the client to criminal defense counsel. The answer is: earlier than feels necessary. Once a criminal investigation is fully underway, voluntary cooperation opportunities may have passed. Below are the clearest signals that criminal defense counsel should be involved.
Direct Signals of IRS-CI Activity
- An IRS-CI special agent leaves a business card, calls the client, or visits the client's home or place of business.
- The client is served with a grand jury subpoena or a federal court summons requiring production of records or testimony.
- A federal search warrant is executed at the client's home or business. A search warrant requires prior judicial authorization; its execution signals an advanced investigation.
- A civil examination has been suspended (all IRS contact unexpectedly ceased) for more than a few weeks without explanation. This may signal a criminal referral.
Client Disclosures That Suggest Criminal Exposure
- The client discloses that prior year returns omitted significant cash receipts across multiple years.
- The client discloses the use of nominee bank accounts, shell entities, or offshore accounts not reported on FBAR or Form 8938.
- The client's records include alterations, backdating, or invoices from entities that the client acknowledges were fictitious.
- The client or an employee made false statements to IRS agents during a prior examination.
- The client's business withheld payroll taxes from employees but did not remit them to the IRS for multiple quarters.
The Referral Conversation
Clients often resist the idea of retaining criminal defense counsel, fearing it signals that they "look guilty" or that engaging an attorney will draw more attention. The civil practitioner should explain that the referral is about protecting the client's rights and position before they are locked in, not about the client's guilt. A qualified criminal defense attorney can evaluate the situation, advise on exposure, and help the client understand the options -- including voluntary disclosure -- at a stage when those options are still available. After a grand jury indictment, options narrow substantially.
IRC 7206(2): The Preparer as Criminal Target
Civil practitioners reading this guide are not just advisors helping clients navigate criminal exposure -- they are potential targets in their own right under IRC 7206(2). The statute requires willfulness, which means a good-faith mistake is a defense. But willfulness can be inferred from a pattern of conduct, from the size and repetition of false items, and from circumstances showing the practitioner had reason to know the representations were false.
IRS-CI has pursued criminal charges against preparers in several recurring scheme types. ERC fraud cases represent the most active current enforcement area: promoters and preparers who knowingly assisted ineligible clients in filing fraudulent ERC claims face both civil preparer penalties under IRC 6694 and criminal prosecution under IRC 7206(2). The civil and criminal tracks are independent; a civil preparer penalty assessment does not preclude a criminal referral. See the ERC Audit Defense Practitioner Guide for ERC-specific examination and penalty exposure.
The Circular 230 consequence of a criminal conviction runs in addition to the criminal sentence. Under Circular 230 Section 10.52, a practitioner who is convicted of any criminal offense under the federal tax laws is subject to immediate suspension from practice before the IRS. Disbarment proceedings typically follow. The OPR does not wait for direct client harm to initiate proceedings based on a criminal conviction. See the OPR Investigation and Circular 230 Practitioner Guide for the OPR sanction process.
If You Are Contacted by IRS-CI
If an IRS-CI special agent contacts you regarding a return you prepared, your immediate step is to retain your own criminal defense counsel before responding in any way. Your civil malpractice insurance may or may not cover criminal defense fees; verify your policy. Do not provide documents, explanations, or voluntary interviews to IRS-CI without criminal defense counsel's advice. Your client's attorney does not represent you; you need separate counsel for your own exposure. Consult the Circular 230 Standards Guide and the Tax Preparer Liability Guide for the civil liability framework that runs parallel to any criminal exposure.
Criminal Exposure Recognition Checklist
Use this checklist to evaluate whether a client situation may involve criminal tax exposure warranting referral to criminal defense counsel. No single item is conclusive; the presence of multiple items significantly increases the risk profile.
- An IRS-CI special agent (not a Revenue Agent) has left a business card, called, or visited the client's home or business.
- The client has received a grand jury subpoena or federal court summons for records or testimony.
- A civil examination that was actively progressing has suddenly gone silent for more than three to four weeks without explanation from the IRS.
- The client discloses cash income that was not reported on one or more prior year returns, and the amounts are material relative to the reported income.
- The client used nominee bank accounts, shell entities, family member accounts, or offshore accounts not reported on FBAR (FinCEN 114) or Form 8938.
- The client's business records contain alterations, backdated documents, or invoices from vendors that the client acknowledges were fictitious or inflated.
- The client or an employee made false statements to IRS agents in an interview during a prior examination.
- The client's business withheld payroll taxes from employees but did not remit those amounts to the IRS for two or more quarters.
- The client received or filed ERC refund claims that may not meet the eligibility requirements and is now under examination or received an IRS compliance check letter.
- You (the practitioner) assisted in preparing a return that you now believe may contain a materially false item -- evaluate your own IRC 7206(2) exposure and consult criminal defense counsel separately from your client's counsel.
Frequently Asked Questions
What is the difference between civil tax fraud and criminal tax evasion?
Civil tax fraud under IRC 6663 is an IRS-imposed penalty of 75 percent of the underpayment attributable to fraud. It is imposed through normal examination and collection processes without criminal prosecution. Criminal tax evasion under IRC 7201 requires the government to prove willfulness, a tax deficiency, and an affirmative act of evasion beyond a reasonable doubt. Both can arise from the same underlying facts. A civil fraud finding does not bar criminal prosecution, and a criminal conviction does not preclude civil fraud penalties. Verify current standards at IRS.gov.
What is the affirmative act requirement under IRC 7201?
IRC 7201 evasion requires the government to prove not just willfulness and a tax deficiency but also an affirmative act: a deliberate step taken to evade or defeat the tax. Affirmative acts include filing a false return, using nominee accounts, altering records, making false statements to IRS agents, structuring transactions to avoid reporting, and diverting funds to conceal income. Mere failure to file or pay, without an affirmative evasion step, does not satisfy the affirmative act element and is instead addressed by IRC 7203 (misdemeanor).
Can a tax preparer be criminally prosecuted under IRC 7206(2) for a client's return?
Yes. IRC 7206(2) makes it a federal felony to willfully aid or assist in the preparation of a false return or document. The preparer does not need to sign the return. Willfulness is required, so a good-faith mistake is a defense -- but willfulness can be inferred from the size and repetition of the false items, the preparer's access to correct information, and the pattern of conduct. IRS-CI has pursued IRC 7206(2) charges against preparers in ERC fraud cases, offshore shelter schemes, and inflated deduction arrangements. Verify current IRS enforcement priorities at IRS.gov/CI.
What should a civil tax practitioner do if an IRS-CI special agent contacts a client?
Advise the client immediately in writing not to speak with the special agent or provide any documents without first retaining criminal defense counsel. Do not make any representations on the client's behalf to IRS-CI. Your Form 2848 power of attorney does not cover criminal investigations. Assist the client in locating federal criminal defense counsel with criminal tax experience. Once criminal defense counsel is retained, coordinate only through that attorney on the civil track.
How long does the federal government have to bring criminal tax charges?
IRC 6531 sets a six-year statute of limitations for most criminal tax offenses, including IRC 7201, 7202, 7206, and related charges. The six years runs from the date of the offense -- for return-based offenses, typically the date the false return was filed. The SOL is tolled when an indictment is filed. The criminal SOL is twice the standard three-year civil assessment SOL, so a matter that is closed for civil purposes may still be within the criminal window. Verify current IRC 6531 text at IRS.gov before advising.
What is the Cheek defense in criminal tax cases?
The Cheek defense (from Cheek v. United States, 498 U.S. 192 (1991)) holds that a defendant who sincerely believed in good faith that the law did not require what the government charges lacked the willfulness necessary for a criminal conviction -- even if the belief was objectively unreasonable. The defense has practical limits: it is a jury question, and jurors assess sincerity against the defendant's sophistication, access to counsel, and the pattern of conduct. Tax-defier positions (e.g., wages are not taxable) are not valid Cheek defenses because they are conclusively settled legal questions.
How does an open IRS criminal investigation affect a parallel civil examination?
When IRS-CI opens a criminal investigation, the civil examination of the same taxpayer is typically suspended. The civil SOL continues to run during the suspension unless the IRS takes action to protect it. Statements made to Revenue Agents during the civil examination before the criminal referral occurred remain available to IRS-CI. The civil practitioner should ensure criminal defense counsel is coordinating strategy for both tracks. The Fifth Amendment right applies to civil IRS proceedings but invoking it carries adverse civil consequences; criminal defense counsel must guide that decision.
Can IRC 7203 (willful failure to file or pay) be charged when IRC 7201 evasion elements are not all present?
Yes. IRC 7203 (misdemeanor) does not require proof of a tax deficiency as a separate element and does not require an affirmative act of evasion. It requires only willfulness and a specific failure (to file, pay, supply information, or keep records). The government frequently charges IRC 7203 as a lesser offense when the affirmative act element for 7201 is weak, or as part of a plea negotiation where the defendant agrees to plead to a misdemeanor in exchange for cooperation or restitution. Verify current statutory text and DOJ charging policies at IRS.gov and the DOJ Tax Division.
