Form 7004 requests an automatic extension of time to file many business income-tax returns — including Form 1120 (C corp), 1120-S (S corp) and 1065 (partnership). 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. With JustFill you upload the blank IRS 7004 PDF, the AI maps each field, and you type the details before downloading it free to file by the deadline.
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.
The official Form 7004 and its instructions (with the Part I form-code table) are free to download from the IRS at irs.gov/forms-pubs/about-form-7004. Open the blank PDF in JustFill to type your EIN, form code and tentative tax, then download the completed form to file by the deadline.
