You enter your business name and EIN, the form code for the return you're extending, and any tentative tax/payment. It extends the time to FILE, not to PAY.

What is Form 7004?

Form 7004 gives a business an automatic filing extension (commonly 6 months) for a long list of returns identified by a form code in Part I. It is filed by the original due date of the return. You provide the entity's name, address and EIN, select the form code, indicate certain entity situations, and enter tentative total tax, payments and the balance due. The extension does not extend the time to pay, so any estimated balance should still be paid. JustFill lets you complete the 7004 online so the form code and figures are correct before you file.
