IRS PTIN Registration Guide: How to Get, Renew, and Use Your Preparer Tax Identification Number
Every compensated tax preparer in the United States must have a valid Preparer Tax Identification Number (PTIN) before preparing or signing a federal tax return. This requirement has been in force since 2011 and is enforced by the Internal Revenue Service under authority derived from IRC Section 6109. This guide covers what a PTIN is, who needs one, how to register, the annual renewal process, and how the PTIN relates to other IRS identification numbers.
What Is a PTIN?
A Preparer Tax Identification Number (PTIN) is a nine-digit identification number issued by the IRS to paid tax return preparers. It begins with the letter "P" (e.g., P12345678). The PTIN replaces the preparer's Social Security Number on tax returns — a privacy protection measure as much as a regulatory requirement.
Under Treasury Regulation § 1.6109-2, a paid preparer must include their identifying number on every return or claim for refund they prepare for compensation. The PTIN is that identifying number for most preparers. Its presence on the return enables the IRS to:
- Identify who prepared each return
- Enforce accuracy and conduct standards
- Track compliance patterns across a preparer's client base
- Investigate complaints against specific preparers
The PTIN does not confer any credential or practice rights beyond the baseline authorization to prepare returns. It is not a license and does not grant representation rights before the IRS.
Who Must Have a PTIN
Any paid preparer of federal tax returns must have a valid PTIN. This includes:
- Independent tax preparers and sole practitioners
- Tax preparation firm employees who prepare or sign returns
- Enrolled Agents
- CPAs who prepare tax returns (even if they use their CPA credential)
- Attorneys who prepare tax returns
- Seasonal preparers working for national chains (H&R Block, Liberty Tax, Jackson Hewitt, etc.)
Who does not need a PTIN:
- Preparers who prepare returns without compensation (unpaid volunteers)
- Employers who prepare tax returns only for their employees
- Individuals who prepare their own personal returns
The rule is compensation-based. If you receive any payment — direct, indirect, or in-kind — for preparing a federal tax return or refund claim, you need a PTIN for that activity.
How to Register for a PTIN: Step-by-Step
PTIN registration is done entirely online through the IRS Tax Professional PTIN System at IRS.gov/ptin. There is no paper alternative for new registrations.
Step 1: Go to IRS.gov/ptin Navigate to the IRS PTIN system. Click "New to the PTIN System? Create an Account."
Step 2: Create your IRS account Enter your name, email address, and create a secure password. You will be asked to verify your email address before proceeding.
Step 3: Complete the PTIN application The online form requires:
- Your Social Security Number (SSN) — required; there is no alternative identification for U.S.-resident preparers
- Your date of birth
- Your home and business address
- Your business name (if applicable)
- Whether you have a professional credential (EA, CPA, attorney, etc.)
- Information from your most recent tax return — used for identity verification
Step 4: Disclose any felony convictions The IRS asks preparers to disclose felony convictions. This does not automatically disqualify you, but failure to disclose accurately can result in PTIN revocation.
Step 5: Pay the fee The current PTIN registration fee is $19.75 per year (as of the current period — verify the current fee on IRS.gov, as Congress can adjust fees by appropriations). Payment is made by credit or debit card.
Step 6: Receive your PTIN Your PTIN is issued immediately upon successful registration. Print or save the confirmation screen. Your PTIN should also be accessible through your online PTIN account.
PTIN Renewal: Annual Requirement
PTIN registration expires each December 31 and must be renewed annually. The renewal window opens in October each year and closes December 31.
Renewal process:
- Log into your account at IRS.gov/ptin
- Confirm or update your personal and business information
- Review and answer the felony conviction and tax compliance questions
- Pay the renewal fee (currently $19.75)
- Confirm your updated PTIN for the new calendar year
Critical: A PTIN must be valid as of January 1 of each filing season. Operating with an expired PTIN — even for a single day into the new year — is a regulatory violation. Set a calendar reminder to renew in October or November each year.
The Annual Filing Season Program (AFSP)
The Annual Filing Season Program (AFSP) is an IRS voluntary continuing education program for non-credentialed tax preparers (those who are not Enrolled Agents, CPAs, or attorneys). Completing the AFSP requirements earns a "Record of Completion" from the IRS for that calendar year.
AFSP requirements:
- Complete 18 hours of continuing education from IRS-approved providers, including:
- 6 hours: Federal Tax Law Refresher course (a specific course type; must be taken from an approved provider)
- 10 hours: Federal tax law topics
- 2 hours: Ethics
Benefits of AFSP completion:
- Limited representation rights: AFSP participants with a Record of Completion may represent clients before the IRS in audits, examinations, and collections — but only for tax years for which they prepared the return, and only before Revenue Agents, Customer Service Representatives, and the Taxpayer Advocate Service. This is more limited than Enrolled Agent representation rights.
- IRS public directory listing: AFSP completers are listed in the IRS's Tax Professional Directory at IRS.gov, which clients can use to verify their preparer
- Competitive differentiation: Displaying an IRS Record of Completion signals to clients that you maintain annual education standards
The AFSP is voluntary — not completing it does not result in any penalty. But the limited representation rights and directory listing make it a meaningful credential for preparers who are not yet Enrolled Agents.
PTIN vs. EFIN vs. CAF Number: What's What
Tax preparers encounter three distinct IRS identification numbers that are easily confused:
PTIN — Preparer Tax Identification Number
- Identifies: The individual preparer
- Who needs it: Every compensated preparer
- Where it appears: On prepared returns (Form 1040 paid preparer section)
- Renewal: Annual, by December 31
- Fee: $19.75/year
EFIN — Electronic Filing Identification Number
- Identifies: An authorized IRS e-file location
- Who needs it: Any preparer or firm that electronically files returns for clients
- Where it appears: In the e-file transmission, not on the return itself
- Renewal: No annual renewal; suitability review when applying
- Fee: No fee (but suitability check required)
- Application: Through e-Services at IRS.gov — takes 4–6 weeks; requires fingerprints from each principal
CAF Number — Centralized Authorization File Number
- Identifies: A tax practitioner authorized to represent a client before the IRS
- Who needs it: Practitioners who submit Form 2848 (Power of Attorney) or Form 8821 (Tax Information Authorization)
- Where it appears: On Form 2848 and Form 8821
- Renewal: Not required; CAF numbers are permanent once issued
- Fee: No fee
- How to get one: Submit your first Form 2848 to the IRS — the CAF number is assigned automatically; no separate application required
Summary: Every paid preparer needs a PTIN. Preparers who e-file need an EFIN. Preparers who represent clients before the IRS using POA forms will receive a CAF number automatically when they file their first Form 2848.
Common PTIN Questions
Does a PTIN require my Social Security Number? Yes. The IRS requires a Social Security Number to register for a PTIN. Non-resident alien preparers who do not have an SSN may follow alternative procedures — consult IRS.gov/ptin for current guidance on international applicants.
What does the PTIN cost? Currently $19.75 per year for registration or renewal. This fee is set by regulation and is subject to change.
Is there a PTIN lookup tool? Yes. The IRS maintains a Tax Professional Directory at IRS.gov where the public can search for preparers. The directory includes AFSP completers and credentialed professionals (EAs, CPAs, attorneys). Not all PTIN holders appear in the directory — only those who have completed the AFSP or hold an IRS-recognized credential.
Can my PTIN be revoked? Yes. The IRS can revoke, suspend, or deny a PTIN for cause, including undisclosed criminal convictions, failure to comply with tax filing obligations, and pattern of errors or misconduct on prepared returns. PTIN revocation is a serious consequence that prevents a practitioner from legally preparing returns.
Can I prepare returns while my PTIN application is pending? No. You must have a valid PTIN before preparing any compensated return. Register before beginning your practice and well before tax season starts.
The Path Beyond the PTIN
The PTIN is the entry point. It authorizes you to prepare returns — nothing more. Practitioners who want to expand into client representation, advisory services, and higher-fee engagements need an IRS-recognized credential.
The recognized credential tiers:
- PTIN only — prepare and sign returns; no representation rights
- AFSP Record of Completion — limited representation rights for returns you prepared
- Enrolled Agent (EA) — unlimited representation rights before the IRS on any matter; requires passing the three-part Special Enrollment Examination or qualifying through IRS experience
