Understanding your CP16 Notice

We sent you this notice to tell you about changes we made to your return that affect your refund. We made these changes because we believe there was a miscalculation. Our records show you owe other tax debts and we applied all or part of your refund to them.

Answers to Common Questions

How can I find out what caused my tax return to change?
Please contact us at the number listed on your notice for specific information concerning your tax return.

What should I do if I disagree with the changes you made?
If you disagree, contact us at the toll free number listed on the top right corner of your notice.

If you contact us in writing within 60 days of the date of this notice, we'll reverse the change we made to your account. However, if you're unable to provide us additional information that justifies the reversal and we believe the reversal is in error, we'll forward your case for audit your case. This step gives you formal appeal rights, including the right to appeal our decision in court before you have to pay the additional tax. After we forward your case, the audit staff will contact you within five to six weeks to fully explain the audit process and your rights. If you don't contact us within the 60 day period, you'll lose your right to appeal our decision before paying the tax.

If you don't contact us within 60 days, the change won't be reversed and you must pay the additional tax. You may then file a claim for refund. You must submit the claim within three years of the date you filed the tax return, or within two years of the date of your last payment for this tax.

What if I disagree with the debt my refund was applied to?
You will need to contact us using the number provided on your notice to discuss your account information.
