If you received notice CP508C, the IRS has told the State Department not to issue or renew your passport. If your debt is resolved the right way, the IRS reverses the certification, and if you have urgent travel, the reversal can be expedited. This is fixable.

What happened
Federal law (Internal Revenue Code section 7345) requires the IRS to certify “seriously delinquent tax debt” to the State Department. For 2026, that means unpaid, legally enforceable federal tax debt over $66,000 (adjusted annually) where the IRS has already filed a lien or issued a levy. Once certified, the State Department will not issue or renew your passport and can revoke the one you hold. The IRS tells you it happened with notice CP508C, sent by regular mail to your last known address, which is why many people learn about it at the passport counter. Source: IRS, Revocation or denial of passport in cases of certain unpaid taxes.
How the certification gets reversed
The IRS reverses a certification, and sends notice CP508R confirming it, when the debt stops being “seriously delinquent.” The realistic paths:
- Pay the debt in full, or
- Enter an installment agreement and keep the payments current, or
- Get an Offer in Compromise accepted, or
- Win a collection due process hearing, or
- Obtain innocent spouse relief for the liability
Filing bankruptcy, identity theft, and certain hardship statuses also block or reverse certification. Which path fits depends on your transcripts, your balance, and your financials, and that is exactly what the free case review sorts out.
Traveling soon? The reversal can be expedited
If you have an open passport application and can document travel within 45 days, the IRS can generally shorten the standard 30-day decertification processing to roughly 9 to 16 days. I build the expedite request into the resolution when the timeline demands it.
Why this needs a professional, not a phone call to the IRS
The certification does not reverse because you promise to pay. It reverses when your account enters one of the qualifying statuses above, and each has its own filing requirements and traps. Getting an installment agreement structured wrong, or defaulting one payment, puts you right back where you started. I am a CPA and Certified Fraud Examiner in Las Vegas. I pull your IRS transcripts, confirm what triggered the certification, and put your account into the qualifying status that fits your finances. If the certification was issued in error, judicial review is available in the U.S. Tax Court or a U.S. District Court under section 7345, and I will tell you if your facts support it.
No outcome can be guaranteed. What can be guaranteed is that your case is handled by one licensed professional, start to finish.
