Under Section 7345 of the Internal Revenue Code (IRC 7345), the Internal Revenue Service may certify a Seriously Delinquent Tax Debt to the U.S. Department of State.
This law, enacted under the FAST Act (Fixing America’s Surface Transportation Act), created the IRS Passport Certification Program.

Many taxpayers do not realize they are at risk of Passport Revocation until international travel plans are disrupted.
The IRS may certify a federal tax debt when the balance exceeds the statutory threshold, required notices have been issued, the liability remains unresolved, and the account has entered the collection process. Certification—formally known as tax debt certification—often follows a filed federal tax lien, exhausted appeal rights, a levy under IRC 6331, or continued noncompliance after collection efforts.

Notice CP508C is the official certification letter sent when the IRS certifies your tax debt to the State Department.
If certification is later reversed, the IRS may issue Notice CP508R to confirm decertification.
Timing becomes critical once Notice CP508C has been issued.
