How Long Can the IRS Collect Back Taxes?
Quick Answer
The IRS generally has 10 years from the date a tax is assessed to collect it. This deadline is called the Collection Statute Expiration Date (CSED), but certain events can suspend or extend the collection period, so the actual date can be later than 10 years from assessment.
Detailed Explanation
The Collection Statute Expiration Date (CSED) is generally 10 years from the date a particular tax is assessed. An account can contain multiple assessments, and each assessment can have its own CSED. The assessment date is not necessarily the return due date.
Certain events can suspend or extend the collection period. Examples include a pending installment-agreement request and related rejection, termination, or appeal periods; bankruptcy; a pending Offer in Compromise and certain rejection/appeal periods; Collection Due Process proceedings; qualifying periods outside the United States; and certain military-service protections. Because these rules can overlap, a simple assessment-date-plus-10-years calculation may not be the actual CSED.
You can review IRS account transcripts for assessment and transaction history, but if the CSED is important to a decision, confirm how the IRS computed it rather than relying on an estimate. After the applicable collection period expires, the IRS generally may no longer collect that assessment, subject to legal exceptions.
Key Points to Remember
- The standard collection period is 10 years from assessment date
- Assessment date is usually when you file your return or the IRS files for you
- Bankruptcy, OIC applications, and CDP hearings pause the clock
- Each tax year has its own separate CSED
- After the applicable CSED, the IRS generally may no longer collect that assessment, subject to legal exceptions
- A pending installment-agreement request can suspend the collection period, and certain rejection, termination, or appeal periods can add time
Steps to Take
- 1Request your IRS account transcript to find the assessment date for each tax year
- 2Use the assessment date as the starting point, then account for any periods that suspended or extended collection
- 3Review your history for any actions that may have tolled the statute
- 4Consult with a tax professional about whether waiting out the CSED makes sense
- 5If pursuing OIC or CDP, understand this will extend your collection window
- 6Monitor each assessment's CSED and confirm the IRS account record before relying on an expiration date
Common Mistakes to Avoid
- ✕Submitting an Offer in Compromise without accounting for the time the CSED is suspended while the offer is pending
- ✕Confusing the filing due date with the assessment date—they're usually different
- ✕Assuming every installment agreement affects the CSED the same way; pending, rejection, termination, and appeal periods have specific rules
