## Facts

Form 8453 is used as a transmittal form and a cover sheet for paper documents and attachments that need to be submitted with a tax return. Essentially, when you file your tax return electronically, but have attachments that can’t be e-filed, you send them with Form 8453.

### Who Should Use Form 8453?

Form 8453 should be used by taxpayers who file their tax returns electronically but must submit paper attachments. However, you may only use it for forms and supporting documents listed on it, so make sure to read it carefully.

### When Is Form 8453 Due?

Form 8453 due date is within three business days after you receive an acknowledgment that the IRS has accepted your electronically filed tax return. Other than that, there’s no strict annual deadline, and the document is only submitted when necessary.

### What Happens If Form 8453 Is Not Submitted?

If you’re required to submit Form 8453 but you don’t, the IRS may invalidate your tax return because it doesn’t have the supporting documents required to verify your figures. That may result in failure-to-file penalties, which equal 5% of unpaid taxes for each month or part of the month your return is late. The maximum penalty is 25%.
