CP 16 Notice

What is the CP 16 notice telling me?
The IRS sends this to inform you that they made one or more changes to your tax return that resulted in a refund. Since you had a balance due on another tax year, the IRS applied all or part of the refund to your balance due.

What do I have to do?
If you agree with the IRS changes, adjust your tax return records to match the IRS changes. If you don't agree with their changes, write or call them at the address or phone number listed on the notice.

You can also view your IRS Online Account for any recent changes.
