What is W-12?
Form W-12, IRS Paid Preparer Tax Identification Number (PTIN) Application and Renewal, is how a tax return preparer applies for a PTIN or renews an existing one by mail. Every person who prepares or substantially helps prepare federal tax returns for compensation must have a valid PTIN and enter it on the returns they sign.
Most preparers use the IRS online PTIN system instead because it is much faster; the paper W-12 can take several weeks to process. PTINs are issued for a calendar year and must be renewed annually, and a user fee applies. Preparers without a Social Security number may need to attach Form 8945 or 8946.
Who files W-12?
- First-time paid tax return preparers applying for a PTIN by mail
- Preparers renewing an existing PTIN for the coming filing season
- Enrolled agents, CPAs, and attorneys who prepare federal returns for compensation
- Foreign preparers and others without an SSN, who file W-12 with the required supplemental form
How to fill out W-12
- Enter your legal name, any prior names, your SSN, and your date of birth, and mark whether this is an initial application or a renewal.
- Provide your mailing address, business address, phone, and email, plus your business website if you have one.
- Answer the questions about felony convictions, federal tax compliance, and your professional credentials.
- Sign and date the form, and attach Form 8945 or 8946 if you have no SSN.
- Download the finished PDF and mail it with the current user fee to the IRS address in the instructions. Or skip the mail entirely: the online PTIN system at irs.gov issues most PTINs the same day.

Frequently asked questions
Who needs a PTIN?
Anyone who prepares, or substantially helps prepare, all or most of a federal tax return or refund claim for compensation. Preparing returns for free, for family, or as an employee handling only your employer’s returns generally does not require one.
How long does a paper W-12 take versus applying online?
The paper form can take four to six weeks to process, while the online PTIN system usually issues or renews a PTIN in about 15 minutes. Use the paper form only if you cannot apply online.
Does a PTIN expire?
Yes. PTINs are valid for one calendar year and must be renewed each year, typically starting in the fall for the following season. A user fee applies; check the current amount at irs.gov.
