The 10-Year Collection Period
The IRS has exactly 10 years from the date of assessment to collect a tax debt. This is set by IRC Section 6502. When the 10-year period expires, the debt is gone. The IRS cannot collect it, cannot levy for it, and must release any liens related to it. This is called the collection statute expiration date, or CSED.
Calculating Your CSED
Each tax year has its own CSED calculated from the date the tax was assessed for that year. If you have multiple years of tax debt, each year expires on a different date. A tax attorney pulls your account transcripts and calculates the exact CSED for each year. This information drives the entire resolution strategy.
Events That Extend the CSED
The 10-year clock can be paused by certain events. Filing an offer in compromise pauses it for the time the offer is pending plus 30 days after rejection. Filing bankruptcy pauses it for the duration of the automatic stay plus six months. Requesting an installment agreement pauses it while the request is pending. Being outside the country for six continuous months pauses it. Signing a waiver extends it by agreement.
Never Sign a Waiver
The IRS sometimes asks taxpayers to sign Form 900, which extends the collection statute. Do not sign this without consulting a tax attorney. There is almost never a good reason to give the IRS more time to collect from you. The IRS may say they need more time to process your offer or agreement, but that processing happens while the statute is already tolled.
Strategic Implications
If your CSED is three years away and you are in currently not collectible status, you may not need to do anything except wait. If your CSED is eight years away, waiting may not be practical and a more aggressive resolution strategy makes sense. The CSED calculation is the foundation of every resolution plan I develop.
