The ten-year collection statute rarely runs a straight ten years. Certain events stop the clock. When the event ends, the clock picks up where it left off, sometimes after an extra tail period. The result is a later expiration date than the simple count would suggest.

This guide is a map of those events and the legal rule behind each one. The arithmetic of adding up suspension days is a separate exercise. The goal here is to know which of your actions, and which events in your life, move the date, so you can make those choices with your eyes open.

Bankruptcy

Section 6503(h) says that in a case under title 11, the running of the collection period is suspended for the period the IRS is prohibited by reason of the case from collecting, and for 6 months thereafter. IRM 5.1.19.3.1 explains that the CSED is generally suspended while the automatic stay is in effect, plus six months.

The same IRM section notes a second, overlapping rule. Section 6503(b) suspends the collection period while the taxpayer's assets are in the control or custody of a court in any federal or state proceeding, and for six months after. So even after the bankruptcy stay ends, the clock may still be paused if substantially all of the debtor's assets remain under the court's control.

Multiple bankruptcy filings can stack suspension periods. The decision to file, and when, has a direct effect on the collection date.

Offers in compromise

Section 6331(k)(1) bars levy while an offer in compromise is pending, for 30 days after a rejection and, if an appeal is filed within those 30 days, while the appeal is pending. Section 6331(k)(3) applies the suspension rule of section 6331(i)(5) to that period, so the collection statute is suspended while the levy bar is in place.

IRM 5.1.19.3.4 confirms the current rule: the CSED is suspended while an offer is pending, for the 30 days after rejection, and during a timely appeal of the rejection. The statute says an offer is pending beginning on the date the IRS accepts it for processing.

An offer filed late in the collection period therefore adds the time it is pending to the end of the period. That is not a reason never to file an offer, but it is a cost to weigh. The library article on compromising a tax liability covers the offer itself.

Installment agreement requests

Section 6331(k)(2) bars levy while a request for an installment agreement is pending, for 30 days after a rejection, while an agreement is in effect, for 30 days after termination and during timely appeals of a rejection or termination.

Here is the important detail. Section 6331(k)(3)(B) applies the statute suspension rule to all of those periods except the period while the installment agreement is in effect. IRM 5.1.19.3.5 states it plainly: the CSED is not suspended while an installment agreement is in effect.

So the request suspends the clock, rejection and termination periods suspend it, but a working agreement does not. The clock runs while you make payments. That is why a payment plan can coexist with an approaching expiration date, and why the IRS sometimes asks for a written extension when the payments will not finish the balance. See the guide to Form 900.

Collection due process hearings

A timely request for a collection due process hearing suspends the clock. IRM 5.1.19.3.3, applying section 6330(e)(1), says the CSED is suspended from the date the IRS receives a timely hearing request until the taxpayer withdraws it or the Appeals determination becomes final, including any court appeals.

There is a floor at the end. If less than 90 days remain on the collection period when the determination becomes final, the period is extended to 90 days.

And there is an exception worth knowing. The same IRM section says the collection statute is not extended for equivalent hearings, the late-request version of the hearing. That trade-off is part of the analysis in the library article on collection due process rights.

Time outside the United States

Section 6503(c) suspends the collection period while the taxpayer is outside the United States, if the absence is for a continuous period of at least six months. If the taxpayer returns and the collection period would expire within six months of the return, the period does not expire until six months after the return.

Short trips do not count. A continuous absence of six months or more does. People who move abroad for work often do not realize this rule is running.

Innocent spouse claims

A request for relief from joint liability also pauses collection against the requesting spouse. IRM 5.1.19.3.6 says that unless collection is in jeopardy, collection by levy or court proceeding against the requesting spouse is suspended for a qualifying claim, and that the collection period is suspended from the filing of the claim until the earlier of a waiver or the end of the 90-day period to petition the Tax Court, or until a Tax Court decision is final, plus 60 days in each case.

The IRM notes that a request for reconsideration is not a qualifying request and does not trigger the suspension.

Taxpayer Advocate requests

Applying for help from the Taxpayer Advocate Service can suspend the clock too. IRM 5.1.19.3.13 says that under section 7811(d), when a taxpayer submits Form 911, the statute of limitations on collection, assessment or both is suspended from the date the Taxpayer Advocate receives the request until the TAS decision date.

The same IRM section adds a practical twist: because of systemic programming limitations, the IRS does not input the codes that reflect this suspension. The date on the IRS screen may not include it, but the legal effect may still be there.

Other suspension events

  • Wrongful seizure or lien on third-party property. Section 6503(f) suspends the period, for the amount involved, from a wrongful seizure of a third party's property until the property is returned or a wrongful levy judgment becomes final, plus 30 days. A similar suspension applies when a third party obtains a discharge certificate under section 6325(b)(4) by posting a deposit or bond, until 30 days after the deposit or bond is resolved or the related judgment becomes final.
  • Refund suits for divisible taxes. Section 6331(i) bars levy on the unpaid portion of a divisible tax, such as employment taxes or the trust fund recovery penalty, while certain refund suits are pending, and section 6331(i)(5) suspends the collection period during that time.
  • Deficiency procedures. Section 6503(a) suspends the periods under both sections 6501 and 6502 after a notice of deficiency while the IRS is prohibited from assessing or collecting, plus 60 days. See the guide on notices of deficiency.
  • Estate tax payment extensions. Section 6503(d) suspends collection of estate tax during certain extensions of time to pay.

What does not suspend the clock

Currently not collectible status does not appear in sections 6503, 6331(k) or 6330(e), and it is not a suspension event. The clock keeps running while an account sits in that status, as described in the library article on currently not collectible rules.

A working installment agreement does not suspend it, as noted above. Neither do ordinary IRS notices, phone calls or a revenue officer's assignment to the case. What matters is a statutory event.

The bottom line

Bankruptcy, assets in court custody, pending offers, pending or rejected installment requests, timely collection due process hearings, continuous time abroad, innocent spouse claims and Taxpayer Advocate requests can all pause the ten-year clock. A working installment agreement and currently not collectible status do not.

Before you file anything, know which category it falls into. The ten-year rule is only half of the answer; the suspensions are the other half.
