What the CP12 Notice Means

A CP12 tells you the IRS corrected one or more mistakes on your return, and the correction changed your refund — either creating a refund, increasing it, or decreasing it. Often no action is needed if you agree. You should receive any adjusted refund within a few weeks if you do not owe other debts.

Deadline

Contact the IRS within 60 days if you disagree; otherwise no action is required.

Why You Received This Notice

A math or calculation error was corrected. A credit such as the Recovery Rebate or Earned Income Credit was adjusted.

What to Do Next

Review the changes and compare them with your return. If you agree, no reply is needed — expect the adjusted refund within about 4–6 weeks. If you disagree, contact the IRS within 60 days with documentation.

What Happens If You Ignore It

If you disagree but do not contact the IRS within 60 days, the change becomes final and you may need to file an amended return to fix it later.
