Generally, the IRS has 10 years from the date your tax is assessed to collect any outstanding tax, penalties, and interest. This 10-year window is called the Collection Statute Expiration Date (CSED).
- The “assessment date” is when the IRS officially records your tax liability. This could be the date you file your return, the date the IRS files a substitute return for you, or the date an audit or amended return results in additional tax owed.
- Each separate tax assessment (for example, from different years or additional penalties) has its own 10-year CSED.
What Happens When the 10 Years Are Up?
Once the 10-year period expires, the IRS can no longer legally collect that particular tax debt. They cannot levy your bank account, garnish your wages, or take other collection actions for that assessment. However, if the IRS placed a levy on a right to future income (such as Social Security or a pension) before the CSED expired, they may continue to collect those payments even after the CSED.
When Does the 10-Year Clock Start?
- If you file your tax return on time, the 10-year period starts from the date the IRS processes and assesses your return.
- If you file late, the 10-year period starts from the actual filing date.
- If the IRS files a substitute return for you, the 10-year period starts from the date of that assessment.
What Can Pause or Extend the 10-Year Period?
Certain actions or events can suspend (pause) or extend the 10-year collection period, giving the IRS more time to collect:
- Bankruptcy: The CSED is suspended while bankruptcy is pending and extended for 6 months after the case ends.
- Installment Agreement Requests: The CSED is suspended while your request is pending, and extended for 30 days if rejected or terminated.
- Offer in Compromise: The CSED is suspended while the IRS reviews your offer, and for 30 days after a rejection.
- Collection Due Process (CDP) Hearing: The CSED is suspended while your hearing or any appeals are pending.
- Innocent Spouse Relief Requests: The CSED is suspended while your request is pending, and extended for 60 days after a final decision.
- Military Service or Living Abroad: Certain military service or living outside the U.S. for 6 months or more can suspend or extend the CSED.
What If You Never Filed a Return or Committed Fraud?
If you never file a return or if the IRS can prove fraud, there is no statute of limitations—the IRS can assess and collect tax at any time.
How Can You Find Out Your CSED?
You can check your IRS account transcript online or by mail to see the CSED for each tax assessment. You can also call the IRS at 800-829-1040 to ask for an explanation of how your CSED was calculated.
What If You Disagree With the IRS’s Calculation?
If you believe the IRS has miscalculated your CSED, you can request a review. If you’re not satisfied with the IRS’s response, you can contact the Taxpayer Advocate Service for assistance.
What Happens If You Pay After the CSED?
If you make a payment after the CSED has expired, you may be entitled to a refund, but you must request it before the refund statute expires (generally within two or three years, depending on your situation).
Key Takeaways
- The IRS generally has 10 years from the date of assessment to collect back taxes.
- The 10-year period can be paused or extended by certain actions, such as bankruptcy, installment agreements, or appeals.
- If you never file a return or commit fraud, there is no time limit for the IRS to collect.
- Once the CSED passes, the IRS can no longer collect that tax debt.
- Always keep good records and check your IRS account transcript to monitor your CSED.
If you’re dealing with back taxes, understanding the CSED can help you make informed decisions and protect your rights. If you have questions about your specific situation, consider consulting a tax professional or contacting the IRS or Taxpayer Advocate Service for guidance.
