It’s a common misconception that only high-profile tax cheats end up in serious legal trouble with the IRS. The reality is, everyday individuals and business owners can find themselves on the wrong side of tax law—sometimes without even realizing it. Whether it’s a math error on a return or a missed disclosure, tax issues can escalate quickly if not handled correctly.
But when the IRS comes knocking, the type of case you’re involved in makes all the difference.
There are two primary categories of IRS litigation: civil and criminal. While both deal with violations of tax laws, they serve very different purposes. Civil tax litigation is typically concerned with recovering unpaid taxes and enforcing compliance. Criminal tax litigation, on the other hand, seeks to punish and deter willful tax violations.
Understanding the distinction can help you respond appropriately, minimize your exposure, and protect your future.
Everything You Need to Know: Civil vs. Criminal Tax Litigation Explained
What Is Civil Tax Litigation?
Civil tax litigation arises when the IRS or a state tax authority disputes how much you owe, typically due to unintentional errors or questionable financial reporting. The underlying assumption is not that you were trying to cheat the system, but rather that you made a mistake, or a series of them.
Common Triggers for Civil Tax Litigation:
Underreporting income unintentionally: For example, forgetting to report freelance income from a 1099-MISC or PayPal account. Many taxpayers don’t realize that digital platforms and “side hustles” count as reportable income.
Overstating deductions: Claiming more deductions than you’re legally entitled to—such as inflating charitable donations without proper receipts or misrepresenting personal expenses as business-related.
Claiming ineligible business expenses: Writing off meals, travel, or office purchases that don’t meet the strict IRS criteria for business expenses.
Filing late returns: Missing filing deadlines year after year can lead to compounding penalties and eventually attract the IRS’s attention.
Math or bookkeeping errors: Even simple arithmetic errors on tax forms, or misclassifying income and expenses in accounting software, can trigger scrutiny.
Civil Penalties May Include:
Additional tax assessments: If the IRS determines that you underpaid, they’ll issue a bill for the difference, plus fees.
Interest charges: Interest begins accruing from the date the tax should have been paid—not when the IRS contacts you.
Accuracy-related penalties (up to 20%): These penalties apply to returns that substantially understate income or overstate deductions.
Late filing or late payment penalties: The longer you wait, the more you owe. Filing even a day late can cost you a percentage of your unpaid taxes.
Tax liens or levies: The IRS can place a lien on your property or seize bank accounts, cars, or real estate to settle your debt.
Garnishment of wages: Your employer may be forced to withhold a portion of your paycheck if you ignore IRS notices.
Unlike criminal cases, civil tax litigations don’t involve jail time, but they can still lead to serious financial strain and damage your credit. A skilled tax litigation attorney can help you navigate the complexities of tax litigation, minimizing potential penalties. With the team at J. David Tax Law by your side, you can navigate tax litigations with confidence, knowing you have expert legal representation protecting your financial future.
What Is Criminal Tax Litigation?
Criminal tax litigation involves intentional and willful violations of tax law. The IRS must prove beyond a reasonable doubt that you knowingly broke the law to evade taxes or deceive authorities.
Common Triggers for Criminal Tax Litigation:
Tax evasion: Deliberately underreporting income, inflating deductions, or hiding assets to reduce your tax liability.
Filing false tax returns: Submitting tax documents that contain false information or forged numbers, knowingly and with intent.
Failure to report offshore income: Failing to file an FBAR (Foreign Bank Account Report) or other required international tax forms like FATCA disclosures.
Creating fictitious deductions or fake invoices: Fabricating transactions that never occurred to artificially lower your taxable income.
Structuring transactions to avoid reporting thresholds: Deliberately breaking up large cash deposits or withdrawals to avoid triggering IRS reports—also known as “smurfing.”
Examples of Criminal Activity:
A business owner who creates shell companies to move money and avoid taxes.
An investor who earns profits through cryptocurrency and never reports any of it.
A doctor who pays employees in cash and keeps a second set of books to hide income.
A landlord who collects rent in cash and never reports a penny of it.
Criminal cases are investigated by the IRS’s Criminal Investigation (CI) Division, a highly specialized unit. These cases can lead to steep fines, criminal records, and significant jail time.
Side-by-Side: Civil vs. Criminal Tax Litigation
How the IRS Chooses Civil vs. Criminal Action
Most tax discrepancies begin as civil matters. However, if an auditor suspects intentional deception, they may escalate the case.
Red Flags That Could Prompt Criminal Investigation:
Multiple years of underreported income: A consistent pattern over time is a red flag for willful evasion.
Falsified documents or receipts: If you’ve submitted doctored invoices or altered forms, the IRS may view this as criminal fraud.
Use of offshore accounts with no disclosure: Hidden international assets are a major trigger, especially if they involve large sums.
Repeated failure to cooperate with IRS audits: Stonewalling, ignoring deadlines, or refusing to provide documentation can escalate a civil case.
Structuring deposits to avoid IRS detection: Repeatedly depositing $9,900 in cash (just under the $10,000 reporting threshold) raises suspicions of smurfing.
When these signs appear, the IRS auditor may pause the audit without explanation and quietly refer the case to CI. You may not know until a federal agent appears—or you’re served a subpoena.
The Role of Intent
Intent is the dividing line between civil and criminal tax matters. In simple terms: Was it an accident, or was it on purpose?
Evidence of Intent May Include:
Repeated misstatements on returns
Fabricated or backdated documents
Efforts to conceal income
Setting up shell entities with no real business purpose
Coaching employees or advisors to lie to the IRS
Criminal tax prosecutions require extensive evidence because the burden of proof is so high.
Investigative Process: From Audit to Indictment
Civil Process:
IRS initiates an audit (either randomly or based on red flags).
The taxpayer receives a notice and is asked to provide documentation.
The IRS reviews records and proposes adjustments.
Taxpayers can accept the changes or appeal.
If unresolved, the case may proceed to Tax Court or U.S. District Court.
Criminal Process:
IRS agents identify signs of fraud or receive a whistleblower tip.
The case is quietly referred to CI.
CI opens a covert investigation—often involving months of data gathering.
Subpoenas are issued, bank records are analyzed, and informants may be used.
Once enough evidence is gathered, the DOJ steps in and files charges.
The case proceeds in federal court and may result in a trial.
The criminal process can be invisible to the taxpayer until the very end. That’s why early legal help is so crucial.
Penalties: What’s on the Line?
Civil Penalties:
Tax owed plus interest
20% accuracy-related penalty
Failure-to-file and failure-to-pay penalties
Potential liens, levies, or wage garnishments
Damage to your credit profile
Criminal Penalties:
Up to 5 years in prison per offense
Up to $100,000 in fines for individuals ($500,000 for corporations)
Restitution payments to the IRS
Probation, community service, or court-ordered financial education
Real-Life Examples
Civil Example:
A freelance writer earns income from multiple clients but forgets to include a $25,000 1099 form when filing. The IRS audits her return, finds the missing income, and assesses back taxes plus penalties and interest. No criminal charges are filed.
Criminal Example:
A startup founder stashes $2 million in undeclared crypto and creates fake consulting invoices to write off income. A two-year CI investigation leads to charges. The founder is convicted of tax evasion and sentenced to 24 months in federal prison.
Hybrid Case:
A retail chain manipulates sales data to reduce tax liability. The CFO is charged criminally, while the company faces civil penalties to recover unpaid taxes and interest.
When Civil Becomes Criminal
An ordinary audit can turn into a criminal investigation under certain circumstances:
Discovery of forged documents
Testimony from whistleblowers
Attempts to obstruct justice or mislead investigators
False statements made under oath or during interviews
If an auditor discovers something suspicious, they’ll typically pause communication and quietly escalate the case.
Your Rights in Tax Litigation
No matter what kind of case you’re facing, you have legal protections:
Right to remain silent (in criminal matters)
Right to legal counsel
Right to challenge IRS findings through appeals
Right to privacy and fair treatment
Right to due process
Always consult a tax attorney before responding to the IRS—especially if anything feels off.
