After ten years—or longer, if paused—the IRS legally loses the right to collect your assessed tax debt.
That’s not just a rule buried in the tax code—it’s a strategic lifeline. Known as the Collection Statute Expiration Date (CSED), this deadline can be a game-changer for those facing long-term IRS pressure.
For tax professionals and taxpayers alike, understanding when the clock starts, what pauses it, and how to track it is essential for building effective relief strategies—and sometimes, letting time do the heavy lifting.
Tolling Events: When the IRS Clock Pauses
The 10-year collection period isn’t always a straight countdown. Certain actions or situations pause (or “toll”) the clock, extending the Collection Statute Expiration Date (CSED) by the length of the delay—not resetting it entirely.
| Tolling Event | Pause Duration | Effect on CSED |
| Bankruptcy | Duration of bankruptcy + 6 months after discharge | IRS cannot collect during the case; CSED extended by total pause duration |
| Offer in Compromise (OIC) | While offer is pending + 30 days after rejection/appeal | Pauses the clock regardless of approval or denial |
| Installment Agreement (IA) | While request is pending + 30 days after denial/termination | Includes appeal time if applicable |
| CDP Hearing / IRS Appeals | From request to final determination (+ up to 90 days) | Especially critical when filed near the original CSED |
| Foreign Absence (>6 months) | Time outside U.S. + 6 months after return | Applies only if taxpayer is abroad for more than 6 continuous months |
| Military Combat Zone Service | Entire period of service + 180 days | Suspension applies under IRC §7508 |
| Court-Controlled Assets | While assets are in litigation, probate, or receivership | Collection suspended until IRS regains access |
Your Insights Applied: Challenges in Calculation & Strategy
Calculating the correct CSED isn’t as straightforward as subtracting tolling time from ten years. Overlapping tolling events—like an Offer in Compromise during military service—don’t pause the clock twice. Only one suspension period applies at a time. Misunderstanding this can lead to overstated CSED extensions and missed opportunities for relief.
Why This Matters:
- IRS transcripts often miscalculate the CSED, especially with overlapping or complex tolling events.
- Relying solely on IRS records can lead to premature settlements, unnecessary payments, or missed defenses.
Your Strategic Advantage as a Tax Attorney:
You know to go beyond what’s on the transcript. Verifying tolling periods manually—cross-checking against transcripts, notices, and client history—is essential to defend clients effectively.
And importantly: the IRS often becomes more aggressive as the CSED nears. That’s when strategic silence, stalling, or targeted action can make or break a resolution.
California’s FTB: The 20-Year Window & Unique Triggers
Unlike the IRS’s 10-year collection statute, California’s Franchise Tax Board (FTB) has a broader reach:
The FTB can collect tax debts for up to 20 years from the date the liability becomes due and payable—also known as the Statutory Lien Date (Cal. Rev. & Tax. Code § 19255).
What Resets the 20-Year Clock?
California’s statute resets more easily than the federal rule. Common resets include:
| Trigger | Effect |
| New tax assessments or audits | Resets the 20-year collection clock |
| Additional penalties or fees | Restarts the statute period |
| Filing errors or unreported income | Triggers a new due-and-payable date |
| Failure to notify FTB of IRS changes | Can eliminate the statute period altogether |
Tolling Events Under FTB Rules
California’s tolling events are similar to the IRS—but often broader:
- Bankruptcy
- Payment plans (Installment Agreements)
- Military service or combat zone duty
- Court-controlled assets (e.g., probate, litigation)
- Federally declared disasters
- Child support enforcement actions
Each of these pauses the 20-year window—sometimes without clear notice to the taxpayer.
Key Insight:
Because California resets the clock more easily and tolls for more reasons, taxpayers often face near-perpetual exposure if not carefully advised. Strategic coordination between IRS and FTB resolutions is critical to avoid prolonging California’s window unnecessarily.
Case Timeline Example & Strategic Use
Let’s break down a hypothetical scenario that highlights how tolling events can stack up—and why precise tracking is essential:
Timeline of Events
| Event | Date / Duration | Effect on CSED |
| IRS tax assessed | April 1, 2015 | Original IRS CSED: April 1, 2025 |
| Bankruptcy filed | June 1 – Dec 1, 2018 (184 days) | + 6-month tolling → CSED extended to ~Oct 2025 |
| Out of U.S. > 6 months | Jan 1 – Aug 1, 2019 | Triggers +6-month pause → CSED to ~Feb 2026 |
California FTB Timeline
| Event | Effect on 20-Year FTB Collection |
| FTB lien filed (based on 2015 debt) | Resets the 20-year clock to 2036 |
| FTB payment plan active (2018–2020) | Tolling adds 2 years → final date extended to ~2038 |
Strategic Takeaway
- Even though the federal CSED is nearing expiration in 2026, California’s FTB may still have over a decade of collection authority remaining.
- Actions like filing an OIC, CDP hearing, or entering an installment plan near the CSED can unintentionally extend IRS collection time.
- Avoid triggering new tolling events unless they serve a clear purpose—especially within the last 1–2 years before expiration.
Conclusion
The IRS’s 10-year clock and California’s 20-year rule aren’t just deadlines—they’re powerful tools in the hands of those who understand them. When tracked and applied correctly, they can mean the difference between years of looming debt and a clean financial slate.
But here’s the catch: tolling events, resets, and overlapping timelines can quietly extend collection windows—often without clients realizing it. That’s where strategy matters most.

FAQs: IRS & California Tax Debt Statutes of Limitations
Q1. What is the IRS Statute of Limitations on Debt Collection?
The IRS has 10 years from the date of assessment to collect a tax debt. This countdown ends on the Collection Statute Expiration Date (CSED).
Q2. What events pause or extend the 10-year CSED clock?
The IRS “tolls” the clock during:
- Bankruptcy (plus 6 months after discharge)
- Offer in Compromise (while pending + 30 days)
- Installment Agreement request (while pending + 30 days)
- Collection Due Process (CDP) hearings
- IRS appeals
- Being outside the U.S. for over 6 months
- Military deferment
- Court proceedings affecting assets
Q3. Can the IRS extend the CSED without notifying me?
No. The IRS cannot extend the statute without your action—but your unwitting decisions (e.g., submitting an OIC) may legally pause the clock.
Q4. What happens when the IRS CSED expires?
The IRS loses all legal authority to collect that debt—no levies, garnishments, or liens. You can request a Certificate of Release if a lien was filed.
Q5. How can I check my CSED?
You can request your IRS account transcript online or via Form 4506-T. A tax professional can interpret it accurately—especially with tolling events involved.
