What Is IRS Notice CP91?

CP91 is a Final Notice of Intent to Levy on your Social Security benefits — a specific version of the levy warning that applies when the IRS intends to collect an unpaid tax debt from your Social Security income. The IRS is authorized under the Federal Payment Levy Program (FPLP) to levy up to 15% of your monthly Social Security benefit until the tax debt is paid in full.

Like the CP90 and Letter 1058, the CP91 triggers your 30-day right to request a Collection Due Process (CDP) hearing with the IRS Office of Appeals. A timely CDP hearing request puts a hold on the Social Security levy while the hearing is pending, giving you time to propose an alternative resolution. If you miss the 30-day deadline, the IRS can proceed with the levy.

For retirees and disabled individuals living primarily or entirely on Social Security income, a 15% levy can represent a significant hardship. If the levy would leave you unable to meet basic living expenses — housing, utilities, food, transportation, and medical care — you can argue economic hardship as grounds to release or reduce the levy at a CDP hearing. The IRS is required to consider hardship claims and can release a levy if collection would "create economic hardship." You can also propose a payment arrangement that you can actually afford based on your income and allowable expenses.

If you're already receiving Social Security and have an unpaid tax debt, don't wait for a CP91 to arrive before addressing it. Setting up an installment agreement or exploring an Offer in Compromise before the levy is issued is far preferable to having your monthly income reduced while trying to negotiate a resolution afterward. If you receive a CP91, act within the 30-day window — protecting your Social Security income from a levy is one of the strongest cases you can make to the Appeals Office for alternative collection treatment.
