Understanding Your CP2566R Notice

We previously sent you a CP63 notice informing you we are holding your refund until we receive one or more unfiled tax returns. Because we received no reply to our previous notice, we have calculated your tax, penalty and interest based on wages and other income reported to us by employers, financial institutions and others.


What you need to do

  • File your tax return immediately, or
  • Accept our proposed assessment by signing and returning the Response form, or
  • Call us if you think you don't have to file.

Answers to Common Questions

What should I do if I disagree with the notice?

Call us at the toll free number listed on the top right corner of your notice. Please have your paperwork ready when you call. If you prefer, you can write to us using the notice's response form and return address listed.

Where do I send my return?

Attach the Response form and send the return to the address listed on the notice.

What should I do if I've just filed my tax return?

You don't have to do anything if you filed your tax return(s) within the last eight weeks.

What should I do if I didn't file my tax return or it's been more than eight weeks since I filed it?

Complete the Response form from your notice. Check the name, Social Security number (or Taxpayer Identification Number), and tax year on your notice. Make sure they match the name, number, and year on the return. Mail us a copy of the tax return. Sign the return and date it; if filing a joint return your spouse must also sign the return. Send the return with the Response form to the address listed on the notice.

What happens if I can't pay the full amount I owe when I file my return?

You can make a payment plan with us. If you owe tax on any return(s) you file, we will use your refund to help pay it.


Tips for next year

File your return on time.

Consider filing your taxes electronically. Filing online can help you avoid mistakes and find credits and deductions that you may qualify for. In many cases you can file for free. Learn more about e-file.
