CP508C Notice: What It Means for Your Passport, and What to Do (2026)
The short answer: a CP508C notice tells you the IRS has certified your "seriously delinquent" tax debt to the U.S. State Department. That means the State Department can deny a new passport, deny a renewal, or revoke a passport you already hold. The certification is reversed once you pay the debt or enter an approved arrangement.
⏱ Your timeline: there's no hard "respond by" date on a CP508C — but the State Department generally holds a passport application open for 90 days while you resolve the debt before denying it. If you have travel booked, act now: a reversal (CP508R) takes the IRS roughly 30 days after you resolve the issue, and longer if you wait.
Why you got a CP508C notice
You received a CP508C notice because the IRS classified your balance as a seriously delinquent tax debt and sent that certification to the State Department. This isn't a surprise letter that comes out of nowhere — it lands after a long collection road that you may have stopped opening.
Under the law, a debt is "seriously delinquent" when all three are true:
- It's a legally assessed federal tax debt above an inflation-adjusted threshold — roughly $66,000 in 2026, including penalties and interest.
- A Notice of Federal Tax Lien has been filed and your appeal rights under that lien have lapsed, or a levy has been issued.
- You're not already in one of the protected categories (more on that below).
The IRS explains the rule on its own page, Revocation or denial of passport in case of certain unpaid taxes, and the notice itself at Understanding your CP508C notice. If you've been ignoring CP504, LT11, or a lien filing, the CP508C is the system catching up with your travel plans.
What happens if you ignore it
The certification doesn't expire on its own, and the State Department acts on the IRS's word. Here's the sequence once you're certified:
- CP508C issued — the IRS notifies the State Department. You're here.
- New application or renewal: the State Department holds your application open for about 90 days so you can resolve the debt, then denies it if nothing changes.
- Existing passport: in many cases your current passport stays valid for ordinary use, but it can be limited or revoked — especially if you live abroad or the IRS specifically requests revocation.
- Meanwhile, the underlying collection continues: the lien stays filed, the balance keeps growing at the monthly failure-to-pay penalty plus interest, and any levy stays in force.
The good news: a CP508C is reversible, and the path to reversal is the same path that fixes the tax debt itself. You're not stuck.
How to get a CP508C reversed
The IRS sends a CP508R — the reversal notice — and tells the State Department to lift the flag once your debt is no longer "seriously delinquent." That happens when any of these is true:
- You pay the debt in full or pay it down below the threshold.
- You enter an installment agreement and keep it current. A debt being paid on time isn't seriously delinquent.
- The IRS accepts an Offer in Compromise, or you sign a settlement agreement with the Department of Justice.
- You request a timely Collection Due Process hearing on a levy connected to the debt.
- Collection is suspended because you requested innocent spouse relief.
- The IRS places the account in Currently Not Collectible status for hardship — collection pauses, and the certification can be reversed.
After you resolve things, the IRS reverses certification within roughly 30 days and notifies the State Department. If you have imminent travel, ask the IRS to expedite — they generally want proof of travel within about 45 days and a copy of your passport.
If you can't pay in full: your real options
Most people who get a CP508C can't write a check for the whole balance. You don't have to. The point is to move the debt out of "seriously delinquent" status — and there's more than one way:
- Installment agreement. A monthly plan stops the debt from being seriously delinquent. For balances that fit, a streamlined installment agreement can often be set up without full financial disclosure. Larger balances may need a partial-pay agreement based on what you can actually afford.
- Currently Not Collectible status. If paying anything would create genuine hardship, the IRS can pause collection. Currently Not Collectible status can support a CP508C reversal while your finances recover.
- Offer in Compromise. Settling for less than the full balance is real — but only when your assets and income genuinely can't cover the debt. Anyone promising to settle for "pennies on the dollar" before reviewing your finances is selling you something. An experienced tax professional can tell you whether you're actually a candidate.
- Penalty relief. First-time abatement or reasonable-cause relief can shrink the balance — and on a debt sitting near the threshold, that can matter.

How to respond, step by step
- Confirm the debt is yours and correct. Log into your IRS online account and compare the balance, tax years, and penalties against your records.
- Check your travel timeline. If you have a passport application pending or travel booked, note the dates — that decides whether you need to ask for an expedited reversal.
- Pick the arrangement that fits your finances. Pay in full if you can; otherwise set up a payment plan, request hardship status, or explore an Offer in Compromise.
- Get the arrangement approved and documented. The State Department won't lift the flag until the IRS sends the CP508R — keep proof of everything.
- If certification is causing serious hardship, contact the Taxpayer Advocate Service, an independent office inside the IRS that helps when normal channels stall.
- If you owe a large balance or have unfiled years, get a professional review first — the order you fix things in changes the result.

CP508C questions, answered
Can the IRS take my passport with a CP508C?
The IRS doesn't take your passport — it certifies your debt to the State Department, which can then deny a new application, deny a renewal, or revoke a passport you already hold. If you have an active passport and no travel planned, the most common effect is being unable to renew until the debt is resolved.
How do I get a CP508C reversed?
The IRS reverses certification once your debt is no longer 'seriously delinquent' — by paying it in full, getting it below the threshold, or entering an approved arrangement like an installment agreement, an accepted Offer in Compromise, Currently Not Collectible status, or a timely Collection Due Process hearing. The IRS then sends a CP508R reversal and notifies the State Department, usually within about 30 days.
What is the dollar threshold for a CP508C in 2026?
Certification applies to a 'seriously delinquent tax debt,' which is a legally assessed federal tax debt over an inflation-adjusted threshold of roughly $66,000 in 2026 (including penalties and interest), where a lien has been filed with appeal rights exhausted or a levy has been issued. The exact figure is adjusted each year for inflation.
Will a payment plan stop the passport certification?
Yes. A debt being paid on time under an IRS installment agreement is not 'seriously delinquent,' so it does not qualify for certification — and if you're already certified, entering an approved payment plan is one of the ways to get a CP508R reversal. The plan must be set up and kept current with the IRS.
I have travel booked soon — can the reversal be expedited?
Possibly. If you have imminent international travel or live abroad, the IRS can expedite reversal once you resolve the debt or enter an arrangement, generally requiring proof of travel within about 45 days and a copy of your passport. The Taxpayer Advocate Service can also assist when certification is causing a serious hardship.
