IRS Passport Revocation Tax Debt Threshold (2026)
The headline number: in 2026 the IRS can certify your tax debt to the U.S. State Department for passport denial or revocation once you owe more than $66,000 in "seriously delinquent" tax debt. The IRS makes this certification through Notice CP508C under IRC Section 7345, and the threshold rises every year with inflation.
You booked a trip, went to renew your passport, and a notice about back taxes is now sitting on your kitchen table. That combination is exactly what the passport-certification rule is built to catch. The good news: it only applies above a specific dollar line, and that line is a public, published number you can check against your own balance.
This study lays out the IRS passport revocation tax debt threshold for 2026 and for every year since the rule took effect in 2018 — the figure reporters, taxpayers, and advisors keep searching for, in one place, with the IRS source cited at the bottom.
Key findings
- The 2026 threshold is more than $66,000. Owe above that in seriously delinquent federal tax debt and the IRS can certify you to the State Department.
- The threshold rises every year with inflation. It has climbed from $51,000 in 2018 to $66,000 in 2026 — a $15,000 increase over nine years.
- The jump from 2022 to 2023 was the largest single-year move — from $55,000 to $59,000, a $4,000 increase reflecting higher inflation adjustments.
- Certification is made through IRS Notice CP508C under IRC Section 7345.
- The IRS does not seize the passport itself. Once certified, the State Department can deny, revoke, or refuse to renew a passport.
- The 2025 threshold was $64,000 and the 2024 threshold was $62,000 — so the line moved up $2,000 in each of the two most recent years.

|---|---|
| 2018 | $51,000 |

| 2022 | $55,000 |
| 2023 | $59,000 |

What this means in plain English
"Seriously delinquent tax debt" is a legal label, not just a big balance. It means an assessed, unpaid federal tax debt — including penalties and interest — that has passed the current-year threshold and for which the IRS has already filed a Notice of Federal Tax Lien (with appeal rights exhausted) or issued a levy. State tax debt, child support, and other non-IRS balances do not count toward the figure.
Because the number is total tax, penalties, and interest combined, many people cross the line without a single new tax bill. Interest and the failure-to-pay penalty grow a $58,000 balance past $66,000 on their own, quietly, over a couple of years of non-payment.
Once your debt qualifies, the IRS sends Notice CP508C and notifies the State Department. From that point the State Department can refuse to issue a new passport, decline to renew an existing one, or revoke a passport you already hold. If you are overseas when this happens, the State Department may issue a limited passport good only for direct return to the United States.
Certain debts are excluded even above the threshold — for example, debt being paid under an accepted installment agreement or Offer in Compromise, debt in Currently Not Collectible hardship status, debt with a pending Collection Due Process appeal, or debt covered by innocent-spouse relief. A federal tax lien is a common trigger on the road to certification; our explainer on IRS Notice of Federal Tax Lien filings statistics shows how often the IRS files them.
A worked example
Say you owe $61,000 in assessed federal tax and stop paying. The failure-to-pay penalty runs at 0.5% per month and interest compounds on top. In roughly two years, penalties and interest can push that balance past $66,000 — the 2026 line — turning a debt that was below the threshold into a seriously delinquent one without any new tax being added. If a lien has been filed, the IRS can then certify it. Resolving the debt before it crosses the line, or getting it into an approved payment arrangement, keeps the certification from happening. You can estimate how fast penalties and interest add up with our IRS penalty and interest calculator.
Owe close to the $66,000 line?
If your balance is near the 2026 threshold — or you've received a CP508C — an experienced tax professional can review whether an installment agreement, Offer in Compromise, or hardship status can stop or reverse the certification. Free, confidential, no pressure.
How the certification gets reversed
The IRS reverses a certification once the debt is no longer "seriously delinquent." That happens when the balance is fully paid, drops below the current-year threshold, becomes legally unenforceable, or is brought under an accepted installment agreement, an Offer in Compromise, or Currently Not Collectible status. The IRS then notifies the State Department it is reversing the certification (Notice CP508R). If you have imminent travel and can prove it, the IRS can expedite the reversal. Setting up an arrangement is often the fastest route — see how tax resolution options work and how a third-party levy or Treasury refund offset can factor into the same debt.
Methodology & source
All figures in this study are the seriously delinquent tax debt thresholds published by the Internal Revenue Service. The threshold is a statutory figure under IRC Section 7345, adjusted annually for inflation. Each year's value is the published amount for that tax year; the passport-certification program began in 2018. We report the IRS figures without rounding or adjustment.

Frequently asked questions
What is the IRS passport revocation tax debt threshold for 2026?
For 2026 the threshold is more than $66,000 in seriously delinquent tax debt. Once your assessed federal tax debt — including penalties and interest — passes that figure and a lien or levy has been issued, the IRS can certify it to the State Department. The threshold is adjusted for inflation every year, up from $51,000 in 2018 and $64,000 in 2025.
Can the IRS really take away my passport for owing back taxes?
The IRS does not take your passport itself. It certifies your seriously delinquent tax debt to the U.S. State Department under IRC Section 7345, and the State Department can then deny a new passport application, refuse to renew your passport, or revoke a passport you already hold. The action is triggered by the certification, not by the IRS directly.
What is a CP508C notice?
Notice CP508C is the letter the IRS sends to tell you it has certified your seriously delinquent tax debt to the State Department. It is the certification itself, not a warning of a future one. If you receive a CP508C, the State Department has already been notified and can restrict your passport, so it should be treated as time-sensitive.
How do I get an IRS passport certification reversed?
The IRS reverses a certification once the debt is no longer seriously delinquent — for example, when it is paid in full, drops below the current threshold, or is brought under an accepted installment agreement, an Offer in Compromise, or Currently Not Collectible status. The IRS then sends the State Department a reversal (Notice CP508R). Timing matters because inflation raises the threshold each year.
