The three-year rule is the first gate an old income tax debt has to get through before bankruptcy can wipe it out. It is not the only gate. But if you fail this one, nothing else matters.
Most people who call me about bankruptcy and the IRS have heard some version of "taxes older than three years go away." That is half right, and the wrong half is what gets people hurt. Here is how the rule actually works.
What the 3-year rule actually says
You will not find a sentence in the Bankruptcy Code that says "the three-year rule." It lives in two provisions that point at each other.
First, 11 U.S.C. § 523(a)(1)(A) says a discharge does not cover a tax "of the kind and for the periods specified in" section 507(a)(8). Second, 11 U.S.C. § 507(a)(8)(A)(i) gives priority to income taxes for a year "for which a return, if required, is last due, including extensions, after three years before the date of the filing of the petition."
Put those together. If the return for a year was due within the three years before you file bankruptcy, the tax is a priority claim, and a priority income tax is not dischargeable. If the due date, counting extensions, falls more than three years before your filing date, the tax clears this gate.
The Supreme Court described it the same way in Young v. United States, 535 U.S. 43 (2002): if the IRS has a claim for taxes whose return was due within three years before the petition, the claim gets eighth priority and is nondischargeable.
The clock runs from the due date, not the filing date
This is where people trip. The three-year clock is tied to when the return was due. Not when you filed it. Not when the IRS assessed it. Not when you got the first scary letter.
Individual income tax returns are generally due on the 15th day of the fourth month after the tax year ends (IRC § 6072(a)), which for most people means April 15. So suppose your 2023 return was due April 15, 2024, you did not extend, and no disaster postponement applied. The three-year line falls on April 15, 2027.
- File bankruptcy before that line and the 2023 income tax is a priority debt that survives a Chapter 7 discharge.
- File comfortably after that line and the 2023 tax passes the three-year test (it still has to pass the others).
Extensions push the date out
The statute says "including extensions." The IRS can grant up to six months to file under IRC § 6081(a). If you extended your 2023 return to October 15, 2024, the three-year line moves to October 15, 2027.
Under the statute's wording, the clock runs from the date the return was last due. Filing early, inside your extension period, does not pull the date back. People who extended out of habit are often surprised to learn that habit cost them six months.
Disaster postponements deserve a hard look
The IRS can postpone filing deadlines for people in federally declared disaster areas under IRC § 7508A. Florida gets these after hurricanes more often than anyone would like. A postponement can change what the "last due" date was for your return, and how that interacts with the lookback is a question to answer with your actual records, not a guess.
Leave a cushion
Lawyers who do this work do not file on the anniversary. Counting mistakes are fatal here, and there is no do-over once the petition is filed. A cushion of days or weeks costs little. Filing one day early can cost you the whole point of the bankruptcy.
The 3-year rule is one of several tests
For an income tax debt to be discharged, each tax year has to pass every test on its own. Besides the three-year rule, the main ones are:
- The 2-year rule. A return has to have been filed, and if it was filed late, it has to have been filed more than two years before the bankruptcy (11 U.S.C. § 523(a)(1)(B)). See the 2-year rule for late-filed returns.
- The 240-day rule. The tax generally has to have been assessed more than 240 days before the filing (11 U.S.C. § 507(a)(8)(A)(ii)). See the 240-day rule after assessment.
- No fraud or willful evasion. A tax tied to a fraudulent return or a willful attempt to evade it is not dischargeable at any age (11 U.S.C. § 523(a)(1)(C)).
Run every year separately. It is common for one year to pass all the tests while the year after it fails. If you want a first pass at the math, the bankruptcy discharge calculator walks through the dates for each year.
The clock can stop: tolling
The three-year period does not always run in a straight line. In Young, a couple filed Chapter 13, dismissed it, and refiled under Chapter 7 once the three years had run, counting from the original due date. The Supreme Court held that the lookback period is tolled while a prior bankruptcy is pending, because the automatic stay kept the IRS from collecting during that time. Their tax was not discharged.
Congress later wrote tolling into the statute. The paragraph at the end of § 507(a)(8) suspends the time periods while a prior bankruptcy stay was in effect or a confirmed plan blocked collection, plus 90 days. It also suspends them while the IRS was barred from collecting because you requested a collection due process hearing and appeal, plus 90 days. If you have filed bankruptcy before or asked for a CDP hearing, your three years may be longer than the calendar says. The details are in how prior bankruptcies and CDP hearings stretch the lookback periods.
What the 3-year rule does not cover
- Trust fund taxes. Taxes you were required to collect or withhold, like withheld payroll taxes, are a separate priority category under § 507(a)(8)(C). The age of the debt does not help you there.
- Penalties. Tax penalties follow their own timing rule in § 523(a)(7), and some penalties can be discharged even when the tax cannot.
- Liens. A discharge ends your personal liability. It does not automatically erase a tax lien already attached to property you owned. The IRS's own manual (IRM 5.9.17.8) notes that a valid pre-petition lien may still be enforced against exempt, abandoned, or excluded property even though the tax was discharged. See why a federal tax lien survives bankruptcy.
What happens if you file too early
In Chapter 7, a tax that fails the three-year rule simply survives. Your other debts may be discharged, but the IRS keeps its claim, with interest still running.
In Chapter 13, priority taxes have to be paid in full through the plan under 11 U.S.C. § 1322(a)(2). That can still be a useful tool, especially when collection is already underway, but it is a very different deal from a discharge. Waiting a few months can change the answer completely. Sometimes you cannot wait, and that is a decision to make with the numbers in front of you.

Get your transcripts before you count anything
Do not count from memory. Pull IRS account transcripts for every year you owe, either through your IRS online account or by requesting them with Form 4506-T. For each year, write down the due date (with any extension), the date the IRS received your return, and every assessment date on the transcript. Those dates decide the case. Your recollection does not, and the IRS has calendars too.
If you have an old income tax balance and want to know whether the calendar is on your side yet, call me at (813) 229-7100. I would rather check the dates with you before you file than explain afterward why the IRS is still sending letters. Every case turns on its own transcripts and dates; this page is general information, not legal advice for your situation.
