File Form 7004 if you wish to apply for a 6-month extension to the US Corporate Tax Filing deadline.
Corporations that use IRS Form 1120 to file annual federal taxes with a calendar year-end date of December 31 should file Form 7004 on or before the corporate tax deadline. With the six-month extension, your new due date is October 15.
- Note that Form 7004 does not extend the time to pay any tax due.
- If your US corporation made any profits, you'll need to pay 21% of this in tax to the IRS by 15th April for Calendar year companies.
