Owe the IRS More Than $66,000? Your Passport Is on the Line in 2026
5 min read · By Jonathan C. Do, Esq. · September 2026
Most people worry about liens and levies when they fall behind with the IRS. Fewer know that an unpaid federal tax balance can quietly cost them the ability to leave the country. For 2026, the IRS threshold for certifying a "seriously delinquent tax debt" to the State Department is more than $66,000 — and once that certification goes out, a passport application can be denied or an existing passport revoked.
Where the $66,000 number comes from
The authority is the FAST Act, signed December 5, 2015, codified at Internal Revenue Code § 7345. It directs the IRS to certify taxpayers with seriously delinquent tax debt to the State Department. The threshold is indexed annually for inflation, and it has climbed steadily:
- 2023 — $59,000
- 2024 — $62,000
- 2025 — $64,000
- 2026 — $66,000
The figure is the total legally enforceable unpaid federal tax debt, including assessed penalties and interest. That matters: a balance that started well under the line can cross it after a few years of accruals. Individual income tax, trust fund recovery penalties, business taxes you are personally liable for, and other civil penalties all count.
Certification isn't automatic at $66,000
Passing the dollar threshold alone doesn't trigger it. The IRS must also have either filed a Notice of Federal Tax Lien with your administrative remedies lapsed or exhausted, or issued a levy. In practice, certification tends to arrive at the tail end of the collection process — after the notices most taxpayers have already been ignoring.
The notice problem: CP508C goes to you, not your representative
When the IRS certifies the debt, it mails Notice CP508C by regular mail to your last known address. Per the IRS, it does not send a copy to your power of attorney. If you have moved, or if you rely on your representative to catch IRS mail, this is the notice most likely to slip past you — until a passport renewal comes back denied.
What is excluded — and what protects you
Debt is not "seriously delinquent" while it is being paid under an approved installment agreement or an accepted Offer in Compromise. The IRS also will not certify a taxpayer who:
- Has an account in currently not collectible status due to hardship
- Has a pending installment agreement or Offer in Compromise request
- Has timely requested a collection due process hearing on a levy to collect the debt
- Has innocent spouse relief pending, is in bankruptcy, is a confirmed identity-theft victim, or is located in a federally declared disaster area
Notice the pattern: filing something and keeping it alive is what keeps you out of the program. Doing nothing is what lands you in it.
The trap most people miss: partial payment doesn't help
The IRS will not reverse a certification just because your balance drops back below the threshold through partial payments or expiring collection statutes. To be decertified, you must fully resolve the certified debt — pay it, settle it, or get it into a qualifying arrangement. Paying $10,000 to get from $70,000 to $60,000 buys you nothing here.
If you already have travel booked
If the State Department denies your application, it holds the file open for 90 days from the date of its letter so you can pay, arrange payment, or fix an erroneous certification. On reversal, the IRS issues Notice CP508R and notifies the State Department within 30 days — but that window can be compressed to roughly 9 to 16 days on an expedited request if you have travel within 45 days, an open passport application, proof of travel, and a copy of the State Department letter dated within the last 90 days.
Before referring a passport for outright revocation, the IRS generally sends Letter 6152 asking you to call and resolve the account. Treat that letter as the last exit before the off-ramp closes.
You can challenge a certification in court
If you believe the certification is erroneous or that the IRS failed to reverse it when required, you can sue in U.S. Tax Court or U.S. District Court — and you do not have to exhaust an administrative claim first. The court can order the IRS to notify the State Department of the error, though it cannot release a lien or levy or award damages in that proceeding.
