Registered Tax Preparer

What is a ptin holder?

Every paid preparer must hold a valid IRS Preparer Tax Identification Number (PTIN). Preparers in this category hold a PTIN but do not list an additional professional credential.

When should you use one?

For straightforward returns — always confirm the preparer signs your return and provides their PTIN.

How to verify a preparer

  • Confirm the credential in the IRS Directory of Federal Tax Return Preparers
  • Ask for their PTIN and make sure they sign the return they prepare
  • For CPAs, attorneys, and state-regulated preparers, check the issuing state board or program
