Understanding Your CP111 Notice

We made changes to your return because we believe there’s a miscalculation. As a result, you are due a refund.


What you need to do

You don't need to do anything. If you haven't received it already, you should receive a refund of the overpaid amount within 4-6 weeks as long as you owe no other taxes or debts we are required to collect.

You may want to

  • Compare the figures on the notice with your tax return.
  • If you agree with our changes, correct the copy of your tax return that you kept for your records.
  • Complete and send us a Form 2848, Power of Attorney and Declaration of Representative, to authorize someone (such as an accountant) to contact us on your behalf.
