Civil Fraud Penalty

The civil fraud penalty is the IRS charge for an underpayment of tax that results from fraud. At 75% of the affected underpayment, it is among the heaviest civil penalties in the income tax system, and its consequences extend beyond the amount. This page explains what the IRS must prove, how the penalty is figured, how it interacts with other penalties, and how to respond if one is proposed. It is general information, and any case involving possible fraud needs individual advice.

What the IRS must show

Fraud means intentional wrongdoing to evade a tax the person knew or believed was owed. The IRS Internal Revenue Manual says that fraud must be proven by clear and convincing evidence, a higher standard than the usual one. Criminal fraud requires proof beyond a reasonable doubt.

Because direct proof of intent is rare, examiners look for patterns the manual calls indicators: understated income, fictitious deductions, accounting irregularities, destroyed records, concealed assets and inadequate records. None of these is proof alone, and a pattern can have an innocent explanation such as poor bookkeeping, a misunderstanding or reliance on an adviser.

How the penalty is calculated

The rate is 75% of the portion of the underpayment due to fraud. If the IRS shows that any part of an underpayment is due to fraud, the whole underpayment is treated as fraudulent unless you prove, by a preponderance of the evidence, that part of it is not.

Example (hypothetical). An audit finds $20,000 of extra tax. The IRS proves that $15,000 of it came from deliberately hidden cash receipts. The fraud penalty is 75% of $15,000, or $11,250. The other $5,000 came from an unsupported deduction the IRS considers negligent, so it may carry a 20% accuracy-related penalty of $1,000. You would owe the $20,000 tax, $12,250 in penalties and interest.

The fraud penalty and the accuracy-related penalty cannot both be charged on the same dollars. When both apply to one return, the IRS allocates the underpayment among the adjustments.

Fraud and failing to file

A parallel penalty exists for returns that are not filed on time because of fraud. The IRS describes it as triple the usual failure-to-file addition under section 6651(f), which works out to 15% per month with a 75% limit, compared with the normal 5% and 25%. See the failure-to-file penalty page for the ordinary rule. The civil fraud penalty applies only if a return was filed. It generally does not apply to a return the IRS prepared for you.

Joint returns and spouses

On a joint return, the penalty does not apply to a spouse unless some part of the underpayment is due to that spouse's fraud. A spouse who knew nothing may also have other protection, such as innocent spouse relief, which is a separate request with its own rules.

Other consequences

• No normal time limit. The IRS tells taxpayers to keep records indefinitely if a fraudulent return was filed. The usual period for the IRS to assess tax does not protect a fraudulent return. See statute of limitations.
• A later amended return does not cure fraud. The IRS manual says a qualified amended return does not erase a fraudulent original return.
• Credit bans. For certain refundable credits, a final finding of fraud in the claim means you cannot claim that credit for 10 years. See improper credit claims and bans.
• Criminal exposure. Civil and criminal cases are different. If you are contacted by IRS Criminal Investigation or a federal agent, consult a tax attorney before talking.

How it moves through the IRS

Fraud penalties generally arise in an examination. The IRS manual says they are subject to deficiency procedures, which means the IRS must send a notice of deficiency before the penalty can be assessed. That notice states the deadline for petitioning the U.S. Tax Court, and the Court cannot consider a late petition. Read our page on the CP3219A notice of deficiency for what to do when one arrives.

How to respond to a proposed penalty

1. Do not ignore the notice or miss a date.
2. Before you answer an examiner's questions, consider authorizing a representative with Form 2848. See IRS audit representation.
3. Gather evidence that explains each item: records, correspondence, preparer files and the advice you received.
4. Dispute the intent finding specifically. The burden belongs to the IRS, so showing an alternative, honest explanation matters.
5. Preserve your right to appeal, by IRS Appeals or by petitioning the Tax Court.

Reasonable cause relief works differently for fraud, because the question is intent. The facts that show you acted in good faith are the core of the response.
