All domestic entities elected to be taxed as a corporation must file Form 1120 every tax year regardless of their taxable income. The due date to file U.S. Income Tax Return for C-corporation (Form 1120) with the calendar year is April 15. If the due date falls on a weekend or other legal holiday, the due date will be on the next business day. 

 If a business cannot file its return on time, it can file a tax extension form 7004, which gives an automatic 6-month extension up to October 15.

U.S. Income Tax Return for C corporation (Form 1120) with fiscal tax years ending June 30 is due by the 15th day of the 3rd month after the end of the entity’s tax year, that is, September 15. By filing form 7004, C corporations with tax years ending June 30 are eligible for an automatic extension period of seven months
When you choose to file a tax extension for C Corp with ExpressExtension, choose the Business Entity Type as 'Corporation' and the Form Type as 'Form 1120- US Corporate Income Tax Return'.
