Most people know the IRS has tools to collect unpaid taxes, including garnishing wages, seizing bank accounts, and placing liens on property. What fewer people realize is that the federal government can also take away your ability to travel internationally, making it much harder to save money on travel by using cheap international flights, last-minute deals, or overseas vacations.
By law, the IRS is authorized to certify taxpayers with "seriously delinquent" federal tax debt to the U.S. State Department, which can then deny a new passport application, refuse to renew an existing one, or revoke a passport you already hold. For 2026, the threshold that triggers this process is more than $66,000 in total federal tax liability, including penalties and interest. Here's how the process works, what it means for your travel plans, and what you can do if you're at risk.

What counts as seriously delinquent debt?
Crossing the $66,000 threshold alone isn't enough to put your passport in jeopardy. Under Internal Revenue Code Section 7345, a debt is only "seriously delinquent" if two additional conditions are met: the IRS must have filed a Notice of Federal Tax Lien against the taxpayer, or issued a levy to collect the debt, and all administrative remedies must have lapsed or been exhausted. In other words, the IRS must have already taken formal legal collection action, which doesn't happen the first time you miss a payment.
Crucially, the IRS will not certify a taxpayer to the State Department if they are actively working toward resolution. Taxpayers are protected from certification if they have an IRS-approved installment agreement in place and are current on payments, have a pending offer in compromise under review, have requested innocent spouse relief under IRC Section 6015, or have an account designated as "currently not collectible" due to financial hardship.
The types of tax debt that qualify include federal income taxes, Trust Fund Recovery Penalties, business taxes for which a taxpayer is personally liable, and other civil penalties.
What happens procedurally?
When the IRS certifies a taxpayer's debt to the State Department, it simultaneously sends a Notice CP508C by regular mail to the taxpayer's last known address explaining the steps available to resolve the situation. Notably, the IRS does not send a copy to a taxpayer's power of attorney — so if you use a tax professional, they may not know about it unless you tell them.
Once the State Department receives the certification, it must deny any new passport application. If an application is already pending when the certification comes through, the State Department will hold it open for 90 days, during which the taxpayer can resolve the debt and have the certification reversed before the application is officially closed. If no resolution occurs within 90 days, the application is denied and the taxpayer must start over.
For taxpayers who already hold a valid passport, the situation is more nuanced. The State Department may — but is not required to — revoke a current passport. Revocation is most likely when the IRS previously reversed certification because a taxpayer promised to pay, then did not follow through.
If the IRS certifies a taxpayer who is currently outside the United States, the State Department may issue a limited-validity passport valid only for direct return to the U.S. A certification can effectively end a trip early and leave a traveler without documents for any future international travel.
How do you resolve it?
The IRS will reverse certification and notify the State Department within 30 days if the tax debt is paid in full, if the taxpayer enters into an approved installment agreement, if an offer in compromise is accepted, or if the certification is shown to be erroneous. In urgent situations — such as an imminent trip — the IRS has an expedited reversal process that can shorten the decertification timeline to as little as 9 to 16 days, but this requires proactive contact with the agency.
One important note: simply reducing the balance below $66,000 does not trigger decertification. The debt must be fully satisfied, legally unenforceable, or covered by a formal payment arrangement. Taxpayers who believe a certification was made in error can file suit in U.S. Tax Court or a U.S. District Court — the court can order the IRS to correct the record, though it cannot release a lien, levy, or award money damages.

Bottom line
If you carry a significant federal tax balance, passport trouble is a real risk, even if you haven't heard from the IRS recently. Certification can occur without a new warning beyond the CP508C notice, which arrives by regular mail and is easy to miss.
For retirees and anyone hoping to start traveling more, the most practical step is to check your IRS account at IRS.gov before applying for a passport renewal, which currently takes six to eight weeks even without complications. If you're on an installment agreement, confirm it's still active and current, as a lapse in payments can restart the certification process. Staying current with the IRS isn't just about avoiding penalties; it's now a prerequisite for keeping your travel options open.
