How Long Can the IRS Collect Back Taxes? The 10-Year Rule Explained

Quick answer: The IRS generally has 10 years from the date a tax is assessed to collect it. That deadline is called the Collection Statute Expiration Date (CSED). Each assessment has its own date, and the clock pauses during events such as bankruptcy, a pending Offer in Compromise, a Collection Due Process hearing or a pending installment agreement request. When the period ends, the remaining balance can no longer be collected.

Robert is 61 and drives a delivery route outside the city. In 2013 his landscaping business failed, and he was left with a federal tax bill of about $38,000. He has made small payments when he could. Every year a new letter comes with a larger number on it. Last spring he asked the question that many people in his position ask: does this ever end?

It does. Tax debt is one of the few debts with an expiration date written into federal law. The rule is simple to state and easy to get wrong, so it is worth understanding properly.

Key Takeaways

• The 10 years start at assessment, not at the end of the tax year.
• Each tax year, and each additional assessment, has its own deadline.
• Bankruptcy, Offers in Compromise, hearings and some other events pause the clock.
• Unfiled years have no assessment, so the clock never starts.
• Voluntary payments do not restart the federal 10-year period.

The Short Answer: Generally 10 Years

The IRS generally has 10 years from the date a tax is assessed to collect it. When the period ends, the remaining balance, including penalties and interest, is no longer legally collectible. The IRS calls the last day the Collection Statute Expiration Date, or CSED.

Three points about this rule cause most of the confusion.

• The clock starts at assessment, not at the end of the tax year. A 2015 return filed in April 2016 is usually assessed a few weeks later, so the ten years run to about mid-2026.
• Each assessment has its own clock. If the IRS adds tax after an audit in 2019, that extra amount has its own ten years, running to 2029.
• Each tax year is separate. A person who owes for five years has at least five different expiration dates.

What Starts the Clock

An assessment is the formal entry of the tax on the IRS's books. It happens when:

• you file a return showing tax due,
• the IRS finishes an audit and records additional tax,
• the IRS processes an amended return that increases the tax, or
• the IRS prepares a substitute return for a year you did not file and records the result.

If you never file and the IRS never prepares a substitute return, there is no assessment and the ten years never begin. Unfiled years do not age away. We wrote about that problem in how to break the IRS cycle of unfiled returns.

What Stops the Clock

This is where Robert's plan to "just wait" ran into trouble. The ten years are ten years of time during which the IRS is legally free to collect. Whenever the law prevents the IRS from collecting, the clock is paused, and sometimes extra time is added afterwards. The most common pauses are:

• Bankruptcy. The clock stops while the automatic stay is in effect, plus six months.
• An Offer in Compromise. The clock stops while the offer is pending, for 30 days after a rejection, and during any appeal of the rejection.
• A Collection Due Process hearing. The clock stops from the hearing request until the decision is final.
• A pending installment agreement request. The clock stops while the IRS considers the request, and for a period after a rejection or termination.
• An innocent spouse claim. The clock stops for the requesting spouse while the claim is decided.
• Living outside the United States. A continuous absence of six months or more suspends the clock.
• Military service in a combat zone. The clock stops during the service and for a period afterwards.

None of these is a reason to avoid a hearing or an offer when one is the right move. But each has a cost in time, and that cost should be counted before the request is filed.

Robert had filed an offer in compromise in 2016 that sat for eleven months before being rejected, and he had been through a Chapter 13 bankruptcy that was dismissed after fourteen months. Together they moved his expiration date back by more than two and a half years.

How Circle of Tax Advisors helps: Under our Tax Advocacy service we obtain your IRS transcripts and calculate the collection expiration date for every year you owe. You see how much time the IRS actually has left before you choose a payment plan, an offer or hardship status.

How to Find Your Own Expiration Date

The IRS does not print the CSED on its notices. You can work it out from an account transcript, which is available through your IRS online account or by request.

1. Get the account transcript for each tax year with a balance.
2. Find the assessment dates. Transaction code 150 is the original assessment from the return. Code 290 or 300 is an additional assessment.
3. Add ten years to each assessment date.
4. Look for events that paused the clock. Codes 520 and 521 mark the start and end of bankruptcy or litigation holds. Codes 480, 481 and 482 mark an offer in compromise. Code 971 entries record requests such as hearings and installment agreements.
5. Add the paused time to the ten years.

Step 5 is where mistakes happen, and they happen on both sides. The IRS's own computer calculation is sometimes wrong, particularly on older accounts with several overlapping events. If a balance should have expired and is still being collected, that can be challenged.

What Happens When the Deadline Passes

On the expiration date, the IRS's legal right to collect ends. The balance for that assessment is written off. A federal tax lien for that debt releases itself and no longer attaches to your property. Levies must stop. If the IRS collects money after the date, it must generally be returned.

Not everything is cleared. Other tax years with later dates remain collectible. State tax agencies follow their own rules and time limits. And expiration is not the same as forgiveness in advance, because up to the last day the IRS has its full powers.

Why Simply Waiting Is Risky

The 10-year rule tempts people to do nothing. Before choosing that path, consider what the IRS can do in the meantime.

• Collection continues until the last day. Wage levies, bank levies and refund offsets are all available to the IRS throughout the period.
• Interest and penalties keep growing. The balance you are waiting out gets larger every month. Some penalties can be removed, as we explain on our penalty abatement page.
• A lien damages your finances. A recorded lien makes it hard to sell or refinance a home or to get business credit.
• The government can sue. For larger debts close to expiration, the government can file suit to reduce the assessment to a court judgment. A judgment extends the time to collect well beyond the original ten years.
• Refunds are taken. Any refund from later years is applied to the old balance.
• Passports can be affected. Large unpaid balances can be certified to the State Department.

How the Deadline Should Shape Your Strategy

Used properly, the expiration date is a planning tool. It changes which resolution makes sense.

Partial payment plans

If you can afford $200 a month and four years remain, the IRS may accept a partial payment installment agreement. You pay what you can until the date arrives, and the rest expires. The IRS reviews these agreements periodically and may ask for updated financial information.

Hardship status

If you cannot pay anything, Currently Not Collectible status stops collection without stopping the clock. For a person on a fixed income with few assets, the debt may expire while the account is in that status.

Offers in compromise

An offer is calculated from your assets and future income. With little time left on the clock, an offer may cost more than a payment plan would, and it pauses the clock while it is pending. With a long time left, an offer may be the better route.

Timing of requests

Because several requests pause the clock, filing them in the wrong order can add years. The sequence should be decided with the dates in front of you.

When we ran the numbers for a situation like Robert's, the oldest and largest year had less than a year left. A partial payment agreement at an amount he could manage carried him to the expiration date for far less than the offer he had been planning to file.

Do not guess at the date. A wrong date leads to the wrong decision in either direction. We calculate it from the transcripts, explain what it means for your options, and tell you the cost of our work before we start. Book a confidential conference.
