When a certified taxpayer applies for a passport, the State Department, in general, will provide the applicant with 90 days to resolve their tax delinquency (such as by making full payment, entering into an installment agreement under section 6159, or IRS acceptance of an offer in compromise under section 7122) before denying the application. If a taxpayer needs their passport to travel within those 90 days, the taxpayer must contact the IRS and resolve the matter within 45 days from the date of application so that the IRS has adequate time to notify the State Department.

Generally, the sole remedy for a taxpayer who believes that a certification is erroneous, or that the Commissioner or specified delegate incorrectly failed to reverse a certification because the tax debt is either fully satisfied or ceases to be a seriously delinquent tax debt by reason of section 7345(b)(2), is to file a civil action in court under section 7345(e). The taxpayer may not go to IRS Appeals to challenge the certification or the decision by the Commissioner or specified delegate not to reverse a certification. However, the taxpayer may contact the phone number in the Notice CP508C to request reversal of the certification if the taxpayer believes that the certification is erroneous.
