How the 10-year clock works
The Collection Statute Expiration Date begins on the date the IRS formally assesses the tax — not the date you filed the return, and not the date you received a notice. For most returns you file yourself, assessment happens shortly after filing. For IRS-prepared Substitute for Returns, assessment happens after the IRS processes their version.
From that assessment date, the IRS has exactly 10 years to collect. If they haven't collected (or tolled the clock) by that date, the debt is extinguished by law. Permanently. No further collection action is possible.
Real Case — Yoav Betsion, EA, IRS Insider Interview
"We had a lady last year who owed $110,000. We waited exactly one year. On the day the 10 years expired, the debt just dropped. She didn't have to call. She didn't have to do anything. It's automatic. The IRS can't collect anymore, and the balance is gone."
What tolls (pauses and extends) the 10-year clock
This is the part most people don't understand — and it's the most important part. Any of the following actions pauses the CSED clock for the duration of the action, plus an additional period after:
- Filing for bankruptcy — clock pauses while the case is active, plus 6 months after discharge
- Submitting an Offer in Compromise — clock pauses while the OIC is pending, plus 30 days after rejection. Important: if the IRS fails to respond within 24 months, the OIC is automatically deemed accepted. And longer if you appeal)
- Requesting an Installment Agreement — clock pauses while the request is pending
- Requesting a Collection Due Process (CDP) hearing — clock pauses while the CDP is pending (and while any Tax Court proceedings following it are active)
- Being outside the U.S. for more than 6 months — clock pauses until you return
- Filing for Innocent Spouse relief — clock pauses during the pendency
- Entering Currently Not Collectible (CNC) status — the clock continues to run in CNC (this is one of CNC's advantages)
⚠ The most common clock-tolling mistake: people who are close to the end of their CSED call the IRS or contact a representative who begins negotiating a payment plan — which pauses the clock right before it would have expired. If you're within a year or two of your CSED and the IRS hasn't successfully collected, the right strategy may be to do nothing.
When doing nothing is the right answer
This goes against every instinct — and against what most tax practitioners will tell you to do. But sometimes the strategically correct move is to not engage with the IRS at all.
Real Case — Yoav Betsion, EA, IRS Insider Interview
"We had a client two days ago — $60,000 owed, CSED expiring March 2026. I told everyone in the office: do not touch it. Don't do anything. Because if you start negotiating a payment plan, you stop the clock. If you request a CDP hearing, you stop the clock. I told the client: I don't want to help you. I don't want your money. We're just going to wait. Because if the IRS hasn't collected in nearly 10 years and there's only months left — I might be committing malpractice if I interfere."
If you're in this situation — close to your CSED with a large balance the IRS hasn't collected — the strategy is to not respond to collection notices, not engage in negotiations, and wait. This requires knowing your CSED (your tax account transcript will show it), having assets that the IRS either doesn't know about or can't easily reach, and having the nerve to let the clock run.
This doesn't work for everyone. If the IRS has a revenue officer actively working your case, if you have wages or bank accounts they can reach with a levy, or if you need to take actions that would toll the clock (like filing for bankruptcy), waiting isn't viable. But for people with limited attachable assets and a CSED close to expiring, it's a real strategy.
How to find your CSED
Your Collection Statute Expiration Date appears on your IRS account transcript — specifically the Tax Account Transcript for each relevant tax year. You can request transcripts from IRS.gov, call the IRS, or have a representative with a Power of Attorney request them on your behalf.
When reviewing the transcript, look for the "CSED" notation or the "Assessment Date" for each tax period, then add exactly 10 years. If there are tolled periods, those add time to the end date — making the calculation more complex and requiring someone who knows what to look for.
Frequently asked questions about the IRS collection statute
Does the 10-year clock apply to all types of IRS debt?
The 10-year CSED applies to assessed income tax and most other assessed federal taxes. Trust Fund Recovery Penalties (§6672 liabilities) have their own assessment and statute rules. Fraudulent returns have no statute of limitations on assessment. Returns that were never filed have no statute of limitations until they are filed or a Substitute for Return is assessed — meaning the IRS's ability to assess is unlimited, even if the collection clock hasn't started.
What happens when the CSED expires — do I have to do anything?
Nothing. The balance extinguishes automatically by operation of law. You don't need to call the IRS or file anything. However, it's worth following up to confirm the balance is showing as zero on your IRS transcript, and to verify that any filed tax liens (which are public records) have been released — liens don't automatically release on their own in all cases.
Can the IRS renew the collection statute?
No. Unlike some state tax authorities, the IRS cannot renew or extend the CSED by filing a lien or taking other action. Once the date passes, collection authority is extinguished permanently. The only ways the CSED date moves are the tolling events listed above — and those must occur before the original expiration date.

What is the exact statutory authority for the 10-year collection period?
IRC Section 6502 establishes the collection statute: 'Where the assessment of any tax imposed by this title has been made within the period of limitation properly applicable thereto, such tax may be collected by levy or by a proceeding in court, but only if the levy is made or the proceeding begun within 10 years after the assessment of the tax.' The operative phrase is 'after the assessment' — not after filing, not after notice, not after you received your first bill. The date the IRS formally records the assessment on their transcript (Transaction Code 150 or 300) is the start of the clock.
Does the CSED appear on my IRS transcript and how do I find it?
Yes. The CSED appears on your Account Transcript (not your Return Transcript) for each tax year. Request your transcript through IRS.gov or by calling 1-800-908-9946. The assessment date appears as Transaction Code 150 (return processed) or 300 (additional assessment). Add exactly 10 years to that date for the base CSED — then account for any tolling periods (OIC pending, installment agreement, CDP hearing, bankruptcy, etc.) that may have extended it. A professional can pull a 'CSED calculation' from the transcript considering all tolling periods.
What exactly tolls (pauses) the CSED — the complete list?
The IRS Collection Statute is tolled (paused and extended) by: (1) A pending Offer in Compromise — from submission date until rejected/returned plus 30 days; (2) A Collection Due Process hearing request — from filing until determination is final plus 90 days; (3) An installment agreement request — while pending; (4) Bankruptcy filing — from petition date until 6 months after discharge or dismissal; (5) Taxpayer's absence from the U.S. for 6+ continuous months; (6) Innocent spouse claim — while pending; (7) Extension agreements signed voluntarily (rare, and taxpayers should almost never sign these). Each tolling period adds time to the end of the CSED.
Can the IRS collect after the CSED expires — and what do I do if they try?
No. After the CSED expires, the IRS's legal authority to collect that tax debt is permanently extinguished. If the IRS attempts to collect after the CSED — by sending notices, levying, or filing liens — those actions are legally invalid. The remedy is to send a written notice to the IRS citing IRC § 6502 and the specific CSED date (with documentation), and if collection continues, file a wrongful levy claim under IRC § 6343 or seek injunctive relief in federal district court. The IRS is required to release any liens on expired balances and cannot renew them.
Is waiting out the CSED considered tax evasion?
No. Passively allowing the collection statute to run is not tax evasion. Tax evasion under IRC § 7201 requires an 'affirmative act' of concealment or fraud — hiding income, falsifying records, or taking other active steps to prevent the IRS from collecting. Simply not calling the IRS, not paying, and not taking any action that would toll the clock is not an affirmative act. Courts have consistently held that passive non-payment, by itself, is not evasion. This distinction is why the strategy is legally defensible when the CSED is genuinely close to expiration.
What happens to a tax lien when the CSED expires?
Under IRC § 6325(a), the IRS is required to release a Notice of Federal Tax Lien within 30 days after the date the statute of limitations for collection expires. The IRS does not do this automatically in all cases — you may need to request it in writing by contacting the Advisory Group at the IRS Campus that filed the lien. Once released, you can request a Certificate of Release and provide it to any credit bureau or title company that still shows the lien in their records.
