Understanding Your CP106 Notice


What this notice is about

We believe you have miscalculations on your return. The changes we made resulted in a balance due.

What you need to do

  • Compare the figures on your tax return with the figures on the notice.
  • Make the changes to your copy of your tax return for your records.
  • Pay the total amount due shown on the notice or call us before the payment due date to make payment arrangements.
  • Allow enough time for mailing your payment (if you decide not to pay electronically) to avoid additional charges of penalties and interest.
  • Contact us in writing within 60 days if you don’t agree with the changes.
