What Is a PTIN? Who Needs One and How to Apply

A PTIN, or Preparer Tax Identification Number, is an eight-digit number preceded by the letter “P” that the IRS issues to anyone who prepares federal tax returns for pay. The fee is $18.75 per year, and every paid preparer must have a valid one before working on a return. You apply through the IRS Tax Professional PTIN System online or by mailing Form W-12.

Who Needs a PTIN

Federal law requires every person who prepares or helps prepare a federal tax return for compensation to include an identifying number on that return.¹ That number is the PTIN. The rule applies broadly: Certified Public Accountants, Enrolled Agents, attorneys, and preparers with no professional credential all need one if they receive any form of payment for their work.²

Both signing and non-signing preparers are covered. A signing preparer has primary responsibility for the return and signs it. A non-signing preparer might handle calculations or data entry without signing but still contributes substantially to the content. If either role is paid, a PTIN is required.

Volunteers are the main exception. If you prepare returns without pay, including through the IRS Volunteer Income Tax Assistance (VITA) or Tax Counseling for the Elderly (TCE) programs, you do not need a PTIN.³

What You Need Before You Apply

Gathering the right information first prevents rejected applications. You’ll need:⁴

Your full legal name, date of birth, and Social Security Number.
Your personal mailing address, your business mailing address, and the legal name of your tax preparation firm.
If you hold a professional credential (CPA, attorney, Enrolled Agent, enrolled actuary, or enrolled retirement plan agent), your license type, the issuing jurisdiction, and the expiration date.
Details from your most recently filed personal federal tax return.
Any prior felony convictions and any issues with your federal tax obligations, such as unpaid balances or unfiled returns.

The felony question covers your entire history, with no “past ten years” cutoff.⁵ A conviction is not an automatic disqualifier, but someone currently incarcerated for a felony will generally not be permitted to get or renew a PTIN. All of this information maps to fields on Form W-12.

How to Apply

Online

Most preparers use the IRS Tax Professional PTIN System at irs.gov. You create an account with your name and email, set a password, and follow the prompts.⁴ After you pay and submit, your PTIN appears on screen right away. The whole process usually takes about 15 minutes.⁶

By Mail

If you’d rather apply on paper, complete Form W-12 and mail it with an original or notarized copy of your Social Security card and one other government-issued photo ID to:⁶

IRS Tax Pro PTIN Processing Center
PO Box 380638
San Antonio, TX 78268⁷

Paper applications take about six weeks to process.⁶

Foreign Preparers Without a Social Security Number

Foreign individuals who don’t have and aren’t eligible for a Social Security Number can still obtain a PTIN. Along with Form W-12, you file Form 8946, the PTIN Supplemental Application for Foreign Persons Without a Social Security Number.⁸ You must include two current, government-issued documents that together verify your identity and your status as a foreign person, and at least one must carry your photograph. Acceptable options include a passport, a U.S. Department of State visa, a foreign military ID, a national ID card, a foreign voter registration card, or a USCIS document such as Form I-766 or Form I-551. Expired documents are not accepted.

One boundary matters here: a foreign preparer who lives outside the United States and obtains a PTIN without a Social Security Number is not authorized to prepare returns for compensation inside the United States.⁸

Fee and Yearly Renewal

The fee is $18.75 per year: a $10 IRS user fee plus $8.75 paid to the third-party contractor that runs the registration system.⁹ The IRS portion is set by regulation.¹⁰ You pay by credit card or electronic check through the online portal, and the fee is non-refundable.⁶

A PTIN expires on December 31 each year. You must renew before preparing any returns for the new tax season, and the renewal window typically opens in mid-October. Online renewal takes about 15 minutes: log in, update your information, and pay.⁶

If you plan to take a full calendar year off, you can either let your PTIN expire or place it in voluntary inactive status through your online account under Account Actions (“Inactivate my PTIN”). Inactive status makes it easier to reactivate later. You cannot prepare returns for pay during any period of inactivity.⁶

What a PTIN Does Not Give You

Holding a PTIN lets you prepare returns for pay. It does not, on its own, let you represent clients before the IRS. That authority depends on your credentials:¹¹

CPAs, attorneys, and Enrolled Agents have unlimited representation rights and can represent any client on any tax matter before the IRS, regardless of who prepared the return.
Non-credentialed preparers who complete the Annual Filing Season Program (AFSP) have limited rights: they can represent clients whose returns they prepared and signed, and only before revenue agents, customer service representatives, and similar IRS employees, including the Taxpayer Advocate Service. They cannot represent clients on appeals or collection matters.
PTIN holders with no credentials and no AFSP Record of Completion can prepare returns only. They have no authority to represent any client before the IRS for returns prepared after December 31, 2015.

The IRS also publishes a public Directory of Federal Tax Return Preparers with Credentials and Select Qualifications. Only PTIN holders who are CPAs, attorneys, Enrolled Agents, enrolled actuaries, enrolled retirement plan agents, or AFSP participants appear in it. Non-credentialed preparers outside the AFSP are not listed.¹²

Penalties for Preparing Without a Valid PTIN

Preparing returns for pay without a valid PTIN triggers a penalty for each return or claim filed. The base statutory penalty is $50 per failure,¹³ adjusted yearly for inflation. For returns filed in calendar year 2025, the penalty is $60 per failure, capped at $31,500 per preparer per year.¹⁴ A reasonable-cause defense is available if you can show the failure was not due to willful neglect. Beyond the fines, the Department of Justice has obtained permanent court orders barring some preparers from the industry entirely.
