Understanding your CP01H Notice

The IRS has locked your account because the Social Security Administration informed us that the Social Security number (SSN) of the primary or secondary taxpayer on the return belongs to someone who was deceased prior to the current tax year (before January 1, 2010 for a 2010 tax return).

Answers to Common Questions
Why am I getting this notice?
You are receiving this notice because the Social Security Administration identified that an SSN used on the federal income tax you filed belongs to an individual who was deceased prior to January 1 of the current tax year (not calendar year). The account was locked by the IRS to prevent identity theft by the misuse of this number.
How can I get the account unlocked?
If the person to whom the Social Security number belongs is erroneously identified as deceased:
- Contact the Social Security Administration and have them remove the date of death.
- Obtain an SSA 2458 letter showing the account has been corrected.
- Follow the instructions for sending the SSA letter along with other information requested on the CP 01H to the IRS Service Center where you filed your original return.
Tips for next year
Be sure to use the correct Social Security numbers when preparing next year's tax return.
