IRS Notice CP12

Refund Adjusted or Corrected

If you’ve received IRS Notice CP12, it means the IRS found a miscalculation on your tax return and has made corrections. As a result, your refund has been adjusted - either increased, decreased, or eliminated entirely.

This notice usually isn't as alarming as a balance-due letter, but it’s still important to review carefully. If the IRS made a mistake, you may have the right to challenge it.


▸ Why Did I Get a CP12 Notice?

CP12 is commonly triggered by:

  • Math errors on your tax return

  • Misreported child tax credits or stimulus/EIP payments

  • Incorrect standard vs. itemized deductions

  • Data that doesn't match IRS records (like W-2s or 1099s)

In short, the IRS adjusted your return based on the data they have — and you’ve either received a different refund than expected or none at all.


▸ What’s in the CP12 Notice?

The CP12 letter will explain:

  • The changes the IRS made to your return

  • Your updated refund amount (or notice that your refund is now $0)

  • An explanation of the adjustment

  • Your rights to dispute or appeal the change


▸ What Should You Do?

  1. Review the changes carefully. Make sure they make sense.

  2. Agree with the IRS? No action is needed — just keep the letter for your records.

  3. Disagree? You typically have 60 days to respond and dispute the adjustment.

  4. No refund when you expected one? You may need to submit documentation or file an amended return.


▸ When to Call a Tax Attorney

In most cases, IRS Notice CP12 doesn’t require legal help, especially if the correction is minor and you agree with it.

However, if you believe the IRS made a significant mistake or if your refund was reduced or eliminated in error, it may be worth speaking with a tax professional.
