What the Form 8453 Individual Income Tax Declaration Is

Form 8453, Individual Income Tax Declaration, is the IRS transmittal form used when submitting certain paper attachments that support an electronically filed individual income tax return. It documents the taxpayer's signature, lists attached supporting documents, and verifies that the taxpayer authorizes the electronic return. The form accompanies any supplemental paper items required by the IRS after the return is e-filed, and it provides a clear chain of custody between the taxpayer, preparer, and the IRS for those physical attachments.
