The IRS has published some tips for choosing a tax return preparer:

  • Check the person’s qualifications
  • Check the preparer’s history
  • Find out about their service fees
  • Ask if they offer electronic filing
  • Make sure the tax preparer is accessible
  • Provide all records and receipts needed to prepare your return
  • Never sign a blank return
  • Review the entire return before signing it, and
  • Make sure the preparer signs the form and includes his or her preparer tax identification number (PTIN).
