Most people think of an IRS problem as a financial problem. A notice, a balance due, a penalty adding up. What they do not expect is to hand their passport to a gate agent and get turned away.
That is not hypothetical. The IRS has the legal authority to get your passport revoked or denied, and it has been using that authority since 2018.
Here is what you need to know.
Short answer
The IRS can certify seriously delinquent tax debt to the State Department, which may deny a passport application or revoke a current passport. For 2026, seriously delinquent means more than $66,000 in legally enforceable unpaid federal tax, including assessed penalties and interest. Certification reverses with full payment, a current installment agreement, an accepted Offer in Compromise, or fixing an erroneous certification. The IRS notifies the State Department within 30 days of resolving the debt, or generally in 9 to 16 days when expedited. The IRS does not publish a fixed State Department restore clock.
The Law Behind It
Congress passed the FAST Act in 2015, which added Section 7345 to the Internal Revenue Code. It authorized the IRS to certify “seriously delinquent tax debt” to the State Department, which can then revoke a current passport or deny a new application.
This is not an audit. It is not a levy. It is a separate track that most taxpayers never see coming until their travel plans are already made.
What Counts as Seriously Delinquent Tax Debt
As of 2026, the threshold is $66,000 in assessed federal tax debt, including penalties and interest. That number is adjusted for inflation each year, so it moves.
To qualify as “seriously delinquent,” the debt also has to be:
- Legally enforceable (meaning the CSED has not expired)
- All collection alternatives exhausted or bypassed, meaning no active installment agreement, no pending OIC, no bankruptcy stay, no CDP hearing in progress
The IRS does not certify every account over $66,000. There is a process. But once certification happens, the State Department moves quickly.
How the Process Works
The IRS certifies the debt to the State Department by sending a notice to the taxpayer first. That notice is called a CP508C. It tells you that certification has occurred and explains your options for getting decertified.
Once the State Department receives the certification:
- If you do not have a passport, your application will be denied.
- If you already have a valid passport, the State Department can revoke it.
- In some cases, the State Department will issue a limited passport valid only for direct return travel to the United States.
There is no grace period built into the process. If you are planning international travel and you have unresolved tax debt above the threshold, this is a real risk.
Who Gets Caught Off Guard
The people most surprised by this are not people ignoring the IRS entirely. They are people who:
- Filed returns but never set up a payment arrangement
- Had an installment agreement that defaulted
- Are on a plan but the balance crept back up through penalties and interest
- Inherited a tax problem through a business, a partnership, or a trust fund penalty situation
The $66,000 threshold sounds high until you factor in several years of compounding penalties and interest on a $20,000 original balance. That math closes faster than most people expect.
How to Get Decertified
The IRS is required to reverse the certification once the qualifying condition is resolved. Decertification happens when you:
- Pay the debt in full
- Enter into an installment agreement (and are current on it)
- Have an Offer in Compromise accepted or pending
- Qualify for Currently Not Collectible status
- Have a CDP hearing pending or a Tax Court case open related to the debt
- Demonstrate the debt is the result of identity theft
Once the IRS reverses the certification, it notifies the State Department. The State Department then has 30 days to act on it. Processing times vary, so this is not an overnight fix. If you have a trip coming up, you cannot afford to start this process the week before you leave.
What to Do Right Now
If you received a CP508C, that notice is your starting gun. The clock is already running and the State Department has already been notified.
Your options narrow quickly once certification happens. The strongest position is to get in front of it before certification, either by resolving the debt or getting into a qualifying status that blocks the IRS from certifying in the first place.
At CLAW Tax Group, we work with taxpayers at every stage of this problem, before the CP508C arrives, after it arrives, and after a passport has already been denied or revoked. If your balance is approaching the threshold or you have already received the notice, the time to act is now.

Common questions
Can the IRS take or restrict my passport for unpaid taxes?
Yes. The IRS can certify seriously delinquent tax debt to the State Department. The State Department may deny a passport application or revoke a current passport. If you are overseas, it may issue a limited validity passport for direct return to the United States. Our team of Enrolled Agents can review a CP508C notice and the rest of your case.
What is the 2026 seriously delinquent tax debt threshold?
For 2026, seriously delinquent tax debt is more than $66,000 in legally enforceable unpaid federal tax, including assessed penalties and interest. The amount is adjusted yearly for inflation.
Who gets certified to the State Department?
Certification generally applies when unpaid legally enforceable federal tax exceeds the threshold. The IRS also must have filed a Notice of Federal Tax Lien with appeal rights used up, or issued a levy. The IRS lists debts and situations it does not certify, such as a timely paid installment agreement or an accepted Offer in Compromise. When it certifies, it mails notice CP508C to your last known address.
How do I get passport certification reversed?
The IRS reverses certification when the debt is fully satisfied or legally unenforceable, when the debt is no longer seriously delinquent, or when the certification is erroneous. It sends notice CP508R when it reverses. Paths the IRS highlights are full payment, a current installment agreement, and an accepted Offer in Compromise. Partial payment that only drops the balance under the threshold is not enough by itself.
How long does it take to reverse passport certification?
The IRS notifies the State Department within 30 days of resolving the debt. With travel within 45 days or living abroad, and an open passport application, expedited processing is generally 9 to 16 days when you provide proof of travel and the State Department letter. After a State Department denial letter, the application stays open for 90 days so you can resolve the debt. The IRS does not publish a fixed number of days for when the State Department restores or reissues a passport after IRS reversal.
