In most cases, the IRS has 10 years to collect unpaid taxes. This deadline is called the Collection Statute Expiration Date, or CSED.
But the 10-year clock does not always run continuously. Certain events can pause the clock or extend the collection period, sometimes by months or even years. Because of this, calculating the true IRS collection deadline can be more complicated than many taxpayers realize.
The Collection Statute Expiration Date (CSED) is generally the deadline for the IRS to collect a tax debt. Once the CSED expires, the IRS typically can no longer pursue collection of that specific tax liability.
However, each tax debt can have its own separate CSED. That means different tax years, and even different penalties, may expire on different dates.
Examples of separate assessments that may have different CSEDs include:
- Original tax balances reported on a filed return
- Additional taxes from an amended return
- Taxes assessed after an IRS audit
- Substitute for Return (SFR) assessments
- Civil penalties
- Certain penalties and interest
The 10-year collection period usually begins when the IRS officially records the tax debt on its books. This is called the assessment date. The assessment date is often different from the date you filed your return.
Many taxpayers are surprised to learn that actions intended to resolve tax debt can temporarily stop the 10-year clock.
For example, applying for a payment plan, filing bankruptcy, or submitting an Offer in Compromise may pause the IRS collection period while the request is being reviewed.
There are generally two ways the collection period can change:
- The clock can pause. During certain events, the IRS temporarily cannot collect. When that happens, the 10-year clock stops running until the event ends.
- Extra time can be added. In some situations, the law gives the IRS additional time after the event ends.
As a result, the actual collection deadline may extend well beyond the original 10 years.
If you apply for a monthly payment plan with the IRS, the collection clock usually pauses while the request is under review.
The clock may also pause:
- For 30 days after a rejection,
- During an appeal, or
- If the IRS proposes to terminate the agreement.
When a taxpayer files bankruptcy, the IRS collection period is generally paused while the bankruptcy case is active. In most cases, the clock is suspended from the date the bankruptcy petition is filed until the case is discharged, dismissed, or closed. The IRS also generally receives an additional 6 months to collect after the bankruptcy concludes.
An Offer in Compromise (OIC) is a request to settle tax debt for less than the full amount owed.
The IRS collection clock is usually paused while the offer is being reviewed. The pause generally lasts until the offer is:
- Accepted,
- Rejected,
- Returned, or
- Withdrawn.
If the IRS rejects the offer, the collection period is generally paused for an additional 30 days. If the taxpayer appeals the rejection, the clock remains paused during the appeal process.
A Collection Due Process hearing allows taxpayers to challenge certain IRS collection actions.
The collection clock is generally paused from the date the IRS receives the DCP request until the final determination is issued, including court appeals. If fewer than 90 days remain on the CSED when the case concludes, the IRS may receive additional time to collect.
If a taxpayer files an Innocent Spouse claim, the collection period for the requesting spouse is generally paused while the claim is being reviewed.
The suspension may continue through:
- The IRS review process,
- The 90-day period to petition Tax Court, and
- Any related Tax Court proceedings.
The IRS also generally receives an additional 60 days afterward.
For taxpayers serving in a combat zone, the IRS collection period is generally suspended during the period of service plus an additional 180 days.
Certain military service situations may pause the IRS collection period. In some cases, the suspension lasts for the period of military service plus an additional 270 days after the IRS receives notification.
If a taxpayer lives continuously outside the United States for 6 months or more, the IRS collection period may be suspended during that time. The IRS may also receive at least an additional 6 months to collect after the taxpayer returns to the United States.
You can usually find your CSED by reviewing your IRS account transcript.
You can request a transcript in several ways:
- Create or access your IRS online account,
- Submit Form 4506-T, Request for Transcript of Tax Return,
- Call the IRS automated transcript line at 888-908-9946.
IRS transcripts can be difficult to interpret, especially when multiple suspension events apply. Many Taxpayers choose to have a Tax Professional review their transcripts to determine the correct collection deadline.
Determining the correct CSED is not always straightforward. Payment plans, bankruptcy filings, offers in compromise, and other events can significantly change the IRS collection deadline.
In some cases, taxpayers believe their debt is close to expiring when the IRS still has years left to collect. Reviewing transcripts carefully and understanding which events paused the clock is critical before making decisions about resolving tax debt.
