Form 7004: More Time to File a Business Return, Not More Time to Pay
Published November 7, 2026
Form 7004 is the form a business uses to request an automatic extension of time to file certain business income tax, information, and other returns. The Instructions for Form 7004 (Rev. December 2025) explain the rules. This post is general information. It is not advice about a specific return.
What the extension covers
The extension is for filing the return, not for paying the tax. The instructions say the extension will be granted if the business completes Form 7004 properly, makes a proper estimate of the tax when that applies, files Form 7004 by the due date of the return, and pays any tax that is due.
Properly filing Form 7004 gives the maximum extension allowed from the due date of the return. The instructions say the automatic period is generally 6 months. There are exceptions. An estate, other than a bankruptcy estate, and a trust filing Form 1041 get an automatic 5½-month extension. A C corporation with a tax year ending June 30 that begins before 2026 gets a 7-month extension, or a 6-month extension if it files Form 1120-POL. For tax years beginning in 2026, the instructions say the automatic extension period is 6 months.
When to file Form 7004
Generally, Form 7004 must be filed on or before the due date of the applicable return. The instructions say to look up the due date in the instructions for that return. Some foreign corporations, certain domestic corporations, and certain partnerships have their own rules in Part II.
The additional extension
If the entity cannot file by the 15th day of the 6th month after the close of its tax year, it can check the box on line 4 to request an additional extension. The instructions say this additional extension is 3 months for partnerships and S corporations, and 4 months for C corporations and filers of Form 1120-POL. The instructions say this is an extension of time to file, not an extension of time to pay.
Tax still due
Interest and penalties can apply to tax that is not paid on time, even when the return is extended. The instructions describe a penalty for late payment of 1/2 of 1% of any tax not paid by the due date, charged for each month or part of a month that the tax remains unpaid. That penalty cannot exceed 25% of the amount due. It is not charged if the business shows reasonable cause for not paying on time.
The instructions also say a corporation granted an extension is not charged a late payment penalty if the tax shown on Part II, line 6, or the amount paid by the regular due date, is at least 90% of the tax shown on the total tax line of the return. The instructions also say a penalty can apply to a return filed after the due date, including extensions, unless the business shows reasonable cause.
Individuals use a different form
Individuals request more time to file on Form 4868. The same idea applies: more time to file, not more time to pay. The individual post Form 4868: More Time to File, Not to Pay covers that form. Corporations that file Form 1120 or partnerships that file Form 1065 should check the due dates in the instructions for those returns before requesting an extension.
Checklist
- Find the due date for the return in its own instructions.
- File Form 7004 by that due date.
- Estimate the tax and pay what is due by the regular due date.
- Check line 4 only if the additional extension period is needed, and remember it does not extend time to pay.
