What is a PTIN and why does it matter?
A Preparer Tax Identification Number (PTIN) is the IRS-issued credential that authorizes you to prepare federal tax returns for compensation. Without a valid PTIN, you cannot legally prepare or sign tax returns — period.
PTINs must be renewed annually, and the IRS has steadily increased the security requirements attached to renewal. Starting in 2024, Form W-12 (Line 11) requires you to certify — under penalty of perjury — that you maintain a Written Information Security Plan.
Bottom line: Your PTIN isn’t just a number — it’s your professional license. Losing it means you can’t prepare returns, can’t e-file, and can’t earn a living as a tax professional.
PTIN renewal security checklist
Verify your IRS account security
Enable multi-factor authentication on your IRS online account. Use a unique, strong password that isn’t shared with any other service. The IRS recommends changing it annually.
Confirm your WISP is current
Your Written Information Security Plan must be up to date before you certify on Form W-12. If you don’t have one, download our free template or get a custom WISP written for your practice.
Verify endpoint protection
Every device used for tax preparation — desktops, laptops, tablets — must have active antivirus or EDR protection. Document which software you use and when it was last updated.
Complete security awareness training
All employees with access to taxpayer data must complete annual security training. Keep signed acknowledgment forms with dates, topics covered, and attendance records.
Run a dark web credential scan
Check whether your PTIN, EFIN, email, or passwords have been exposed in any data breaches. If compromised credentials are found, change them immediately and document the remediation.
Review and update access controls
Verify that only authorized staff can access taxpayer data and tax preparation software. Remove access for former employees. Document who has access to what.
Submit your renewal
Log in to the IRS PTIN system, pay the $50 renewal fee, and certify your security compliance on Form W-12. Keep a copy of your renewal confirmation for your records.
Form W-12 Line 11: WISP Certification
The most significant change to PTIN renewal in recent years is the addition of Line 11 on Form W-12, which asks whether you maintain a Written Information Security Plan. Your answer is certified under penalty of perjury.
If you answer "Yes"
If you certify falsely
This isn’t a checkbox you can skip. If the IRS audits your practice and you can’t produce the WISP you certified having, the consequences are immediate and severe.
PTIN theft: a growing threat
Criminals are actively targeting PTINs to file fraudulent returns. If your PTIN is stolen, fraudulent returns filed under your number trigger IRS investigations against you — not the thief.
Warning signs your PTIN may be compromised
If you suspect compromise: Contact the IRS Identity Protection Specialized Unit at 1-800-908-4490 immediately. File Form 14039 (Identity Theft Affidavit), notify affected clients, and report to local law enforcement.

PTIN requirements — frequently asked questions
The IRS requires all PTIN holders to maintain a Written Information Security Plan (WISP), use multi-factor authentication on IRS accounts, keep endpoint protection current on all devices used for tax preparation, complete annual security awareness training, and certify compliance on Form W-12 during renewal. These requirements apply to every paid preparer regardless of firm size.
The annual PTIN renewal period typically runs from October through December, though the IRS opens the system earlier some years. The renewal fee is $50. Your PTIN expires on December 31 if not renewed, and you cannot legally prepare returns without a valid PTIN. We recommend starting the renewal process in October to allow time for any security documentation you may need to prepare.
Yes — PTIN theft is a growing form of tax fraud. Criminals use stolen PTINs to file fraudulent returns, and the IRS may not distinguish between legitimate and fraudulent filings initially. This can result in IRS investigations, suspended e-filing privileges, and significant time spent proving your innocence. Running regular dark web scans for your credentials and monitoring your e-file counts are essential preventive measures.
Yes. Form W-12 Line 11 now asks whether you maintain a Written Information Security Plan, and your answer is made under penalty of perjury. If you certify that you have a WISP without actually having one, you face perjury charges, PTIN revocation, and FTC enforcement. If you don’t have a WISP yet, download our free template or get a custom one written for your practice before your renewal deadline.
Contact the IRS Identity Protection Specialized Unit immediately at 1-800-908-4490. File Form 14039 (Identity Theft Affidavit) with the IRS.
