Understanding Your CP01H notice


What this notice is about

We issue the CP01H notice when the IRS receives a tax return that contains a Social Security number (SSN) for an account that we locked because our records indicate the TIN belongs to an individual who died prior to the tax year of the return submitted.

The IRS locked your account because records within the Social Security Administration (SSA) informed us that the SSN of the primary or secondary taxpayer on the return belongs to someone who died prior to the tax year of the return submitted for processing.

What you need to do

If you think our records are incorrect:

  • Contact the Social Security Administration (SSA) to correct the situation. We cannot help you until SSA verifies that the primary or secondary taxpayer is not deceased.
  • After SSA corrects the information, follow the instructions shown on your CP01H notice to file your return. You must file within 3 years from the date on your notice to receive your refund.
