A Preparer Tax Identification Number, or PTIN, is an eight-digit IRS-issued number that anyone who prepares federal tax returns for pay must include on every return they touch. The number usually starts with the letter “P” (for example, P12345678). Getting one, or renewing one, costs $18.75 and takes about 15 minutes through the IRS online PTIN system.
Who Needs One
Federal law requires a current PTIN for anyone who prepares or helps prepare “all or substantially all” of a federal tax return or refund claim for compensation.1Internal Revenue Service. PTIN Requirements for Tax Return Preparers That covers signing preparers, non-signing preparers who do the substantive work, and supervised employees at tax firms. Enrolled agents need a PTIN too, whether or not they actually prepare returns.2Taxpayer Advocate Service. Getting a PTIN
You do not need one to prepare your own return, to help family or friends without charging, or to prepare returns as a volunteer through an IRS-sponsored program like VITA. The line is compensation. Once money changes hands for preparation work, the PTIN requirement kicks in.

Paper applications take four to six weeks to process.4Internal Revenue Service. Instructions for Form W-12 IRS Paid Preparer Tax Identification Number Registration
Foreign Preparers Without an SSN
Preparers who don’t have and can’t get a Social Security Number apply with Form 8946 alongside Form W-12. Two identity documents are required, at least one bearing a photo, and the IRS recommends submitting notarized copies rather than originals. Processing takes about six weeks.5Internal Revenue Service. Form 8946, PTIN Supplemental Application For Foreign Persons Without a Social Security Number
One boundary matters here: a foreign preparer living outside the U.S. who gets a PTIN through this route is not authorized to prepare returns inside the United States for compensation.5Internal Revenue Service.

Renewing Each Year
Every PTIN expires on December 31 of the year it was issued, so you renew before the next filing season.3Internal Revenue Service. IRS Reminds Tax Pros to Renew PTINs for the 2026 Tax Season The renewal window opens in the fall. For the 2026 season, the IRS opened renewals in late October 2025. Renewal runs through the same online system, costs the same $18.75, and takes under 15 minutes.
Missing the window doesn’t erase your number permanently. You can reactivate an expired PTIN in a later year by going through renewal and paying the current fee. What you cannot do is prepare returns for compensation during any period when your PTIN is not active.
What a PTIN Does and Doesn’t Let You Do
A PTIN satisfies the identifying-number requirement under 26 U.S.C. § 6109(a)(4) and must appear on every return or refund claim you prepare for pay.6Office of the Law Revision Counsel. 26 USC 6109 – Identifying Numbers On its own, though, it carries limited authority.
Enrolled agents, CPAs, and attorneys have unlimited rights to represent clients before the IRS. A preparer holding only a PTIN does not. Since 2016, the only non-credentialed preparers with any representation rights are those who complete the IRS Annual Filing Season Program (AFSP), a voluntary continuing-education program that earns a Record of Completion and limited representation rights before revenue agents and customer service representatives, and only for returns the AFSP preparer personally prepared and signed.7Internal Revenue Service. Annual Filing Season Program Without AFSP and without a professional credential, a PTIN holder can prepare returns for pay but has no authority to represent the taxpayer before the IRS.
Penalties for Preparing Without One
Preparing returns for compensation without a valid PTIN triggers penalties under 26 U.S.C. § 6695(c). The base statutory penalty is $50 per return, capped at $25,000 in a calendar year, and both figures are adjusted annually for inflation.8Office of the Law Revision Counsel. 26 USC 6695 – Other Assessable Penalties with Respect to the Preparation of Tax Returns for Other Persons For returns filed in 2025, the per-return penalty was $60 and the annual cap was $31,500.9Internal Revenue Service. Tax Preparer Penalties
Money isn’t the only exposure. The IRS can seek a court injunction barring you from preparing returns at all, and the Office of Professional Responsibility can take disciplinary action against practitioners subject to Circular 230.10Internal Revenue Service.
