Passport Certification of Tax Debt (CP508C)

Under the FAST Act, the IRS must identify taxpayers whose debt crosses the annually adjusted threshold and certify them to the State Department. The CP508C is your copy of that certification. It typically lands only after the collection ladder has already run: bills, reminders, a CP504, and usually a lien filing or a final levy notice like the LT11. When the certification is later reversed, the IRS sends a CP508R and notifies the State Department.

If you apply for or renew a passport while certified, the State Department holds the application open for 90 days and sends you a letter, giving you time to fully pay, enter a payment arrangement, or correct an erroneous certification before the application is denied. Ninety days sounds generous until you are assembling an offer in compromise or negotiating an installment agreement against it; if travel is on your calendar, start the resolution before you apply, not after the denial letter.

Plan the sequence backward from the trip. Getting an agreement approved, having the IRS process the reversal, and having the State Department act on it are three separate steps handled by two separate agencies, and none of them is instant. The earlier the arrangement is in place, the more ordinary your passport experience will be.

The IRS reverses certification when the debt is fully paid, becomes legally unenforceable, or stops being seriously delinquent. In practice, the last path is the workable one, because a debt in any of these states is excluded from certification:

• An approved installment agreement with payments being made on time.
• An accepted offer in compromise with payments on schedule.
• A timely requested Collection Due Process hearing that is still pending.
• Collection suspended for an innocent spouse request or by bankruptcy.

The IRS also will not certify accounts in currently not collectible status, in a federally declared disaster area, in bankruptcy, or identified as victims of tax-related identity theft. If you believe the certification itself is wrong, because the debt is not yours, was already paid, or fits an exclusion, call the number on the notice and contest it with documentation rather than waiting for the State Department side of the process to force the issue. In other words, every mainstream resolution path doubles as passport repair. The mechanics of each are covered in our payment plan guide and offer in compromise guide, and the whole ladder is summarized in what to do when you owe the IRS.
