Tax Relief AnswersIRS Statute of Limitations on Collections
The short answer
The IRS generally has 10 years from the date a tax was assessed to collect it, including penalties and interest. That deadline is called the Collection Statute Expiration Date (CSED), and once it passes the IRS can no longer collect the balance. The rule comes from 26 U.S.C. 6502 and is explained on the IRS time IRS can collect tax page, last updated June 27, 2026. Several events pause or extend the 10 years, so the real date is often later than assessment plus 10 years.
What starts the clock, and what stops it
The clock starts at assessment, not at the tax year and not at the filing deadline. For a return you filed, assessment usually happens shortly after the IRS processes it. If you did not file and the IRS prepared a substitute return, the clock starts when the IRS assesses that tax. One account can have several assessments, each with its own CSED, for example an original balance and a later audit adjustment.
| Event | Effect on the 10-year period, per the IRS page |
|---|---|
| Installment agreement request pending | Suspended while the IRS reviews; 30 days added if the request is rejected or withdrawn; suspended during an appeal |
| Offer in Compromise pending | Suspended during review; 30 days added after a rejection; suspended during an appeal |
| Bankruptcy | Suspended from the petition until the case is discharged, dismissed or closed, plus 6 months |
| Collection Due Process hearing | Suspended until the hearing is withdrawn or finally decided; if fewer than 90 days remain afterward, extended to 90 days |
| Innocent spouse request | Suspended until a waiver is filed or the 90-day Tax Court window ends, plus 60 days; a Tax Court case suspends it until final decision |
| Combat zone service | Suspended from entry to exit, plus 180 days |
| Military service | Suspended for the service period plus 270 days after the military notifies the IRS |
| Living outside the United States 6 months or more | Suspended for that time; may be extended at least 6 months after return |
Not on the list: Currently Not Collectible status and an approved payment plan that is being paid. The clock keeps running during both.
How to find your date
The CSED is not printed on IRS notices. It appears on your account transcript, which you can get through your IRS online account, by mail with Form 4506-T, or by calling 800-908-9946. In the transactions section, each assessment has a three-digit transaction code with a date beneath it; the IRS page says that date is generally the CSED plus any added time. For questions about the date, the IRS lists 800-829-1040 for individuals and 800-829-4933 for businesses. If you believe the IRS has the date wrong and cannot resolve it, the Taxpayer Advocate Service takes those cases on Form 911.
Steps
- Request an account transcript for each year you owe.
- Write down the assessment date and the transaction code dates for each balance.
- List every event from the table above that applied to you, with start and end dates: bankruptcy filings, offers, hearing requests, payment plan requests, time abroad.
- Add the suspension time to assessment plus 10 years. That is your estimate.
- Compare it with the transcript date. If they differ by months, call the IRS and ask how the date was computed.
- Decide what the date means for you. A balance expiring within a year or two often calls for a different approach than a balance with eight years left; see the partial payment plan and Offer in Compromise pages.
Common mistakes
- Counting from the tax year. A 2016 return filed late in 2020 was assessed in 2020, so its 10 years run from 2020.
- Filing an Offer in Compromise or a hearing request to "run out the clock". Both suspend the clock, and a rejected offer adds 30 days.
- Assuming a levy on wages ends on the CSED. The IRS page says a levy on future income can continue to collect payments that were already attached.
- Paying after the date passed without checking. The IRS page says you may request a refund of amounts paid after the CSED, within the refund deadline.
- Expecting a notice. The IRS does not send a letter when a balance expires; the transcript simply shows it written off.
FAQ
Does IRS tax debt really expire after 10 years?
Yes. Under 26 U.S.C. 6502 the IRS generally has 10 years from assessment to collect, and it cannot collect a balance after the CSED, but the period is suspended or extended by bankruptcy, offers, hearings, payment plan requests and time outside the country.
How do I find my Collection Statute Expiration Date?
It is on your account transcript, available in your IRS online account or by Form 4506-T. The date under each transaction code is generally the CSED including added time.
Does a payment plan stop the 10-year clock?
The clock pauses while the IRS reviews the request, and 30 days are added if the request is rejected. Once the plan is approved and being paid, the clock runs normally.
What happens to a federal tax lien when the collection period ends?
The IRS page says it can no longer collect after the period expires. A filed lien notice is tied to the balance, and the lien is released when the underlying liability is no longer enforceable.
