To extend your deadline to file your Form 1120-POL you have to file Form 7004. Your organization will get an automatic extension of 6 months' time to file your Form 1120-POL upon the approval of your Form 7004. At this point, ExpressTaxExempt does not support the extension form but you can use our affiliate program ExpressExtension to file your Form 7004.
The due date to file your Form 7004 is the same as the original deadline to file Form 1120-POL which is on the 15th day of the 4th month of the taxable year.
