Yes. Illegal gains are taxable under federal law, and the tax is owed the same year you take the money. Internal Revenue Code Section 61 defines gross income as “all income from whatever source derived,” and the IRS reads that phrase to reach every dollar you control, whether it came from wages, an embezzlement scheme, a bribe, or the sale of stolen property.1Office of the Law Revision Counsel. 26 USC 61 – Gross Income Defined Publication 525 says it directly: report bribes in income, and report stolen property at its fair market value in the year you take it.2Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income
Where Illegal Income Goes on Your Return
Illegal income belongs on the same return as everything else you earned that year. Income from an ongoing criminal enterprise that functions like self-employment, such as profits from a business built around illegal activity, goes on Schedule C. One-off illegal income, like a bribe or embezzled funds, goes on Schedule 1 as other income.2Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income
Stolen property has one narrow exception. If you return the property to its rightful owner in the same tax year you took it, you do not have to include it in income. The window closes at year end.2Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income
Why the Law Treats Stolen Money as Income
The rule comes from two Supreme Court decisions. In 1927, United States v. Sullivan held that a Prohibition-era bootlegger could not refuse to file a return just because his business was illegal. The Court said there was no reason “why the fact that a business is unlawful should exempt it from paying the taxes that, if lawful, it would have to pay.”3Justia. United States v. Sullivan, 274 U.S. 259 (1927)
Sullivan handled profits from an illegal business. The harder question was money taken from someone else. The Court settled that in James v. United States (1961), a case involving a union official who embezzled more than $738,000 and never reported it. The Court held that a taxpayer receives income whenever they acquire funds “without the consensual recognition, express or implied, of an obligation to repay and without restriction as to their disposition.” It does not matter that the embezzler has no legal right to keep the money or that a court might later order it returned. What matters is that the taxpayer exercised real control.4Justia. James v. United States, 366 U.S. 213 (1961)
That test also draws the line between illegal income and a genuine loan. A real loan comes with a mutual agreement to repay, so the borrower gains no net wealth. Embezzlement, extortion, and bribery have no such agreement, which is why they trigger tax the year the money changes hands. Labeling stolen money a “loan” on paper does not change the substance if no true agreement to repay ever existed.4Justia. James v. United States, 366 U.S. 213 (1961)
The Year You Control the Money Is the Year You Owe
Federal tax uses an annual accounting period, and income is taxable in the year you receive it under a claim of right, without restriction on how you use it. If you treated the money as yours during that year, the IRS treats it as yours too.
This holds even when your right to the money is disputed. A lawyer who receives a contested fee owes tax on the full amount that year, even if a court later orders it returned. An embezzler owes tax the year of the theft, even if restitution follows years later. The system taxes what you controlled during the year, not how the story ends.5Office of the Law Revision Counsel. 26 USC 1341 – Computation of Tax Where Taxpayer Restores Substantial Amount Held Under Claim of Right
If You Later Have to Pay the Money Back
Restitution or a civil judgment does not undo the original tax bill. You cannot go back and amend the return for the year you took the money. Instead, the repayment generates a deduction in the year you actually pay it.
For smaller amounts, that deduction just reduces taxable income in the repayment year. The problem is bracket mismatch. If you were in a high bracket when the income was taxed and a low bracket when you repaid, the deduction gives back less than the tax you originally paid.
Section 1341 provides a safety valve when the repayment exceeds $3,000. It lets you compute your tax two ways and take whichever is lower:5Office of the Law Revision Counsel. 26 USC 1341 – Computation of Tax Where Taxpayer Restores Substantial Amount Held Under Claim of Right
- Take the deduction in the repayment year and compute your tax normally with the deduction included.
- Compute the repayment-year tax without the deduction, then subtract the tax you would have saved in the original year had the income never been reported.
The second method effectively credits you at the original year’s higher rate, which usually helps when that year’s bracket was higher than your current one. You do not file a special election, but you do need to run both calculations and attach the details to your return.
Deductions If You Run an Illegal Business
An illegal business that is not drug trafficking can generally deduct ordinary and necessary business expenses under Section 162, the same as any legal business. The Supreme Court confirmed this in Commissioner v. Sullivan (1958), allowing a gambling operation to deduct rent and wages. Taxing illegal businesses on gross receipts while taxing legal ones on net income would be a policy choice for Congress to make explicitly, and the Court would not read it into the code.6Legal Information Institute. U.S. Constitution Annotated – Income from Illicit Transactions
Congress did make that choice for drugs. Section 280E denies all deductions and credits to any business trafficking in Schedule I or II controlled substances.7Office of the Law Revision Counsel. 26 USC 280E – Expenditures in Connection with the Illegal Sale of Drugs Because cannabis remains Schedule I federally, state-licensed marijuana dispensaries fall inside 280E. They report all their revenue but cannot deduct rent, payroll, or marketing, which produces an effective tax rate well above what a comparable legal business pays.
Section 162 also carves out a few specific expenses. Bribes and kickbacks paid to government officials are never deductible, and bribes or kickbacks that violate a generally enforced state or federal criminal law lose their deductibility as well.8Office of the Law Revision Counsel. 26 U.S. Code 162 – Trade or Business Expenses
Can You Refuse to Report on Fifth Amendment Grounds
No, not as a blanket refusal. Sullivan rejected the argument, calling it “an extreme, if not an extravagant, application of the Fifth Amendment to say that it authorized a man to refuse to state the amount of his income because it had been made in crime.”3Justia. United States v. Sullivan, 274 U.S. 259 (1927) The IRS takes the same position: there is no constitutional right to refuse to file based on self-incrimination, and blanket assertions of the privilege do not excuse the failure to file or report income.9Internal Revenue Service. Anti-Tax Law Evasion Schemes – Law and Arguments (Section IV)
The privilege is narrower than that. Sullivan allowed that if a specific line on the return would force a taxpayer to incriminate themselves, they can assert the privilege on that particular line. You file the return, report the income amount, and note a Fifth Amendment objection on the line that would identify the source. You do not leave the whole return blank.3Justia. United States v. Sullivan, 274 U.S. 259 (1927)
What Happens If You Don’t Report It
Not reporting illegal income leaves you with a tax debt and hands prosecutors a second felony charge to stack on top of the underlying crime. Section 7201 makes willfully attempting to evade any federal tax a felony carrying up to five years in prison and a fine of up to $100,000 for individuals ($500,000 for corporations).10Office of the Law Revision Counsel. 26 USC 7201 – Attempt to Evade or Defeat Tax Eugene James was convicted under Section 7201 for the years he hid his embezzled income, and adding tax evasion charges alongside the underlying offense is a common federal enforcement pattern because the failure to report creates independent, easily provable criminal liability.4Justia. James v. United States, 366 U.S. 213 (1961)
If Your Spouse Hid Illegal Income on a Joint Return
Joint filers are normally both on the hook for the tax, but Section 6015 offers innocent spouse relief when one spouse had no knowledge of an error that understated tax owed, and unreported income qualifies as such an error.11Internal Revenue Service. Innocent Spouse Relief
You have to show that you did not know and had no reason to know about the unreported income. A reasonable-person standard applies, so if someone in your situation would have noticed, the IRS will deny relief. There is an exception for domestic abuse: if you signed the joint return under pressure or threat, or fear of your spouse kept you from questioning it, you may still qualify even with some awareness.11Internal Revenue Service. Innocent Spouse Relief
File Form 8857 within two years of receiving an IRS notice of an audit or additional tax due tied to the error. Relief covers only the tax attributable to your spouse’s income; your own income on the joint return stays your responsibility.11Internal Revenue Service. Innocent Spouse Relief
