IRS CP508C Notice: Passport Certification — Seriously Delinquent Debt
A CP508C notice means the IRS certified your tax debt as 'seriously delinquent' (over $66,000 for 2026, adjusted for inflation each year, with a lien or levy in place) to the State Department, which can now deny your passport application or renewal — and in some cases revoke it.
What a CP508C actually means
Certification happens when a large assessed debt has passed through lien/levy stages with no resolution. The State Department then blocks passport issuance and renewal until the IRS reverses the certification.
Reversal is formulaic: pay the debt in full or below the threshold, or enter an installment agreement or an accepted Offer in Compromise, and the IRS reverses the certification (typically within 30 days), with expedited handling possible for imminent travel. Hardship (Currently Not Collectible) status is one of the reasons the IRS doesn't certify a debt in the first place — but it isn't listed as a way to reverse a certification that's already been made.
How to recognize a real CP508C
The IRS passport certification program under Internal Revenue Code section 7345, enacted in the 2015 FAST Act. The sample notice comes from 'Attn: Passport' at a Philadelphia P.O. box and tells you the IRS has already certified your debt to the State Department.
- The heading reads 'Notice of certification of your seriously delinquent federal tax debt to the State Department'.
- The amount due includes penalty and interest computed to 30 days from the notice date. The notice covers only the certified part of your debt, so you may owe more than it shows.
- A 'Your billing details' table lists each certified period by taxpayer ID, tax period, form number (such as 1040 or 941), amount owed, interest, and penalty.
- The last page says 'Return this page with your payment' and has its own mailing address for payments.
- It explains that you can challenge the certification in U.S. District Court or the U.S. Tax Court without first going through IRS administrative steps.
What to do, step by step
- 1Don't wait for a trip to force the issue — decertification takes time even when expedited.
- 2Verify the balance and confirm you're actually certified (your IRS online account shows it).
- 3Enter a qualifying resolution: full payment, an installment agreement, or an accepted Offer in Compromise.
- 4Once resolved, the IRS sends CP508R (reversal) to the State Department — ask for expedited decertification if you have imminent international travel.
Illustrative example
Example: Renee's passport renewal is denied before a work trip
Renee (an illustrative taxpayer) owed about $78,000 for 2019 and 2020. That is above the 2026 certification threshold of $66,000, and a levy had already been issued. She received a CP508C, ignored it, and later applied to renew her passport ahead of a work trip in six weeks. The State Department denied the renewal.
She called the number on the CP508C and set up an installment agreement. Debts paid through an approved installment agreement aren't considered seriously delinquent, so this made her eligible for decertification.
Because she had travel coming up, she asked for expedited decertification. She sent proof of travel (her flight itinerary) and a copy of the State Department's denial letter. The IRS says expedited cases are generally reversed in 9 to 16 days instead of the standard 30. Once the IRS reversed the certification, it sent her a CP508R and notified the State Department.

Mistakes that make a CP508C worse
- Asking for Currently Not Collectible status and expecting it to reverse the certification. The IRS doesn't certify accounts already in hardship CNC status, but it does not list CNC as a reason to reverse a certification that already happened. The listed routes are full payment, an approved installment agreement, an accepted offer in compromise, and the other reversal grounds on the IRS page.
- Waiting until a trip is booked. Standard decertification takes about 30 days. The expedited 9 to 16 day timeline requires proof of travel and a copy of the State Department's denial letter.
- Assuming your power of attorney will handle it automatically. The notice warns that its contents may not be covered by the POA you have on file, so contact your representative directly.
- Not reading the billing table closely. It can include business periods (such as Form 941) and only the certified part of the debt. Other balances may not appear.
What happens if you ignore a CP508C
The certification stays in place. The State Department generally won't issue or renew your passport and may revoke your current one. If you apply while certified, the IRS says the State Department holds the application for 90 days so you can resolve the debt. Any refund you're due will also be applied to the certified debt.

Common questions
Can the IRS really take my passport?+
The IRS doesn't take it — it certifies the debt to the State Department, which denies new passports/renewals and can revoke existing ones. A qualifying payment arrangement reverses the certification.
How fast can I get decertified if I have a trip coming?+
Entering an installment agreement or other resolution triggers reversal, normally within 30 days; the IRS can expedite it with proof of imminent travel and the State Department's denial letter — the IRS has described expedited decertification as taking roughly 9–16 days.
