What this notice is about

We locked your account to prevent identity theft and will not process your tax return because we received information that your Social Security number (SSN) or your spouse’s SSN (if filing a joint return) belongs to someone who died prior to the tax year of the return.

What you need to do

Verify that you entered your SSN or your spouse’s SSN correctly on your return and it matches your Social Security card. If you confirm that you entered it correctly:

  • Contact the Social Security Administration (SSA) to correct their records.
  • Follow the instructions shown on your CP01H notice to file your return once SSA corrects it.

Why did I receive this notice saying my Social Security number (SSN) belongs to a deceased person?

This could happen if our records show an SSN on your tax return matches a number for someone who died prior to the tax year of your return. As a result, we locked your account and won’t process your return until you resolve the issue.

How can I get the account unlocked and what documents do I need to submit?

After the Social Security Administration (SSA) corrects their records, please send the following documents to the address listed at the top of your notice:

  • A copy of your CP01H notice
  • A written request to unlock the account
  • Your tax return with original signatures

Also include a photocopy of at least one of the following:

  • Passport
  • Driver’s license
  • Social Security card
  • Other valid U.S. federal or state government-issued identification

What to do next

  • Write down the date on the letter today.
  • Look the number up on irs.gov yourself. Don’t trust a link or phone number from anyone else.
  • If it says you owe money or proposes changes to your return, take it to a licensed CPA, EA or tax attorney before that date.
