Verify that the Preparer Tax Identification Numbers (PTINs) you enter into your tax software for yourself and your employees are correct. Using an incorrect PTIN could lead to penalties and unnecessary contact with IRS.
What Can I Do to Protect my EFIN and PTIN?
To protect your practice, the IRS suggests that you check your account to verify that you filed the number of returns showing under your EFIN. You can access your e-file information through e-services.
Report any misuse of your EFIN number by contacting the e-services Help Desk at 1-866-255-0654.
For more information about EFINs, see FAQs—About Electronic Filing Numbers
If you suspect someone else has used your PTIN, call the PTIN hotline at 1 877-613-PTIN or you can submit the Form 14157, Tax Return Preparer Fraud or Misconduct Affidavit.
