How to Prepare for the Phone Call with IRS Customer Service

Before you call IRS customer service, be sure you know or have the following information handy:

  • Social Security numbers and birth dates for those who were on the return you are calling about
  • An Individual Taxpayer Identification Number (ITIN) letter if you don’t have a Social Security number (SSN)
  • Your filing status – single, head of household, married filing, joint, or married filing separate
  • Your prior-year tax return, in case the IRS needs to verify your identity before answering certain questions
  • A copy of the tax return you’re calling about
  • Any letters or notices the IRS has sent you

Note that the IRS will only speak with the taxpayer or their legally designated representative. You cannot call about someone else’s account without a valid Form 2848 or Form 8821.

  1. What do you do if two tax returns were submitted for the same person in error. I cannot reach a person to speak to and it seems like everything is just at a standstill.

  2. I am the Treasurer for the Piedmont Ambulance District (PAD) in Piedmont, SD. How do I find out whether the PAD is registered as a 501-3C organization? If so, how do I get proof that we are a 501-3C organization
