Form 15103: Form 1040 Return Delinquency

Form 15103, Form 1040 Return Delinquency, is a reply form that comes with an IRS notice. It lets the person the notice is addressed to tell the IRS why a Form 1040 is shown as not filed for a year.

The form lists several circumstances: a return was already filed, the person addressed on the notice has died, the person does not think a return is required for that year, or there is a refund or estimated tax payment from a prior year to apply. Each has its own lines to complete.

The form says to complete both sides and send it back in the enclosed envelope, with the IRS address showing through the window. It ends with a signature under penalties of perjury. You can fill out the PDF free in your browser on this page and download it without an account.
