What is a CP13 notice?

Mark Steber

Chief Tax Information Officer

Published on: June 22, 2020

IRS notices are letters sent to inform taxpayers of important tax information. Each one is different, but we can explain what the CP13 is about.

Understanding your CP13 notice

The IRS updated your tax return due to a miscalculation they discovered. However, the changes were administrative and did not affect your taxes so there is no additional refund or balance due.

Type of Notice

Tax return error

Why you received the CP13 notice

You received a CP13 notice because the IRS found a miscalculation in your tax return. The change did not result in a change in taxes so there is no additional refund or balance due.

Likely next steps

To find out what the changes are, contact the IRS at the phone number in the upper right-hand corner of the notice. You should make those changes to your tax return copy you keep for your records.

If you disagree with the notice, you need to contact the IRS at the toll-free number listed on the CP13 in the upper right-hand corner or by mail within 60 days.

CP13 Notice deadline 

There is no deadline unless you disagree with the IRS changes. Then, you have 60 days from the date of the notice to contact the IRS.
