IRS CP575: what it means and what to do
The CP575 is a digital notice confirming your business's Employer Identification Number (EIN). It's available only through the Business Tax Account and can be used in place of the original CP575A-J notice or Letter 147C. This summary is drawn from the IRS page for the CP575, last checked on October 13, 2026.
Why you received a CP575
- You may need to confirm your EIN when opening a bank account for your entity or getting other business services
What to do
- Keep this notice in your permanent records
- Use your EIN on everything you send to the IRS and the Social Security Administration about your business
- Make several copies to use whenever someone asks you to verify your EIN
- Report any change in the responsible party to the IRS within 60 days using Form 8822-B
Get your records together first
Most notices come down to matching what the IRS has on file against your own records. Before you reply, pull the return the notice refers to, the bank statements and income forms for that year, and any payment confirmations. If your books are reconciled to the bank, that comparison takes minutes instead of days.
