I got a CP20 notice from the IRS

If you got a notice from the IRS, don’t worry. We’ll do our best to help you figure out what to do next.

The CP20 notice means that the IRS believes you incorrectly claimed one or more deductions or credits. As a result, your refund is less than you expected. 

You’ll need to:

  • Review your notice and compare the IRS’ changes to your tax return.
  • Complete the response form and mail it to the address listed on the notice.

For additional questions regarding your notice, contact the IRS.
