What the letter says

You filed an amended return or asked for a correction, the IRS processed it, and you owe the difference plus any interest from the original due date.

Check it

Compare the changes listed to your Form 1040-X. The IRS occasionally applies a change to the wrong line or year.

Agree

Pay by the date on the notice. Interest runs from the original due date of the return, not from the amendment.

Disagree

Write within 60 days, say which change is wrong, and attach the amended return.

What to gather

  • The notice
  • Your amended return (Form 1040-X) with the explanation section
  • The original return

Write back

The CP14 response letter tool builds the response in the order the IRS reads it. Fill it in, review it, print it, and send it with copies of the documents above and the notice stub on top.
