All professional tax preparers are required to have a valid Preparer Tax Identification Number (PTIN) in order to legally file federal tax returns on behalf of their clients. Whether you’re just getting started or you’re a seasoned pro, maintaining an active PTIN is essential for staying compliant with IRS regulations.
A Preparer Tax Identification Number (PTIN) is a unique ID issued by the IRS to tax professionals. If you are paid to prepare or assist in preparing federal tax returns, you are legally required to obtain and use a PTIN.
This requirement applies to all tax preparers, including enrolled agents, and remains necessary regardless of whether you work independently or as part of a firm. Every individual preparing returns for compensation must have their own PTIN—even when operating in the same office.
You can apply for a PTIN online in about 15 minutes, or you can complete and mail in a paper Form W-12.
Note: The processing time for paper applications is four to six weeks.
Begin by creating your online account through the IRS PTIN system. This account will be used to manage your application and renewals.
You’ll need to provide the following information:
Social Security Number
Personal details: Name, date of birth, and mailing address
Business details: Name, address, and phone number

Explanations for any criminal convictions or outstanding tax obligations (if applicable)
Professional certification details, if applicable (e.g., CPA, attorney, EA)
Once the application is complete, your PTIN will be issued immediately. Keep it safe and ensure you include it on all client tax returns you prepare.

Most tax preparers need an Electronic Filing Identification Number. If you plan to prepare more than 11 tax returns in a year, you are required to use IRS e-file, and so you will need an EFIN.
