Corp Tax Deadlines
I must not have been clear in my earlier post about the due date of corporate income tax returns because a lot of people are worrying about theirs being due this Monday. The due date is March 17 only for those corporations with a fiscal year ending December 31. This is the case for all S corporations.
However, those C corps who have taken my advice to use a different tax year will have a different due date. It will be 2.5 months after the end of the fiscal year. For example, a corp with a fiscal year ending September 30 will have a deadline for filing the tax return (1120) or extension (7004) by December 15. The extension moves the deadline to six months later.
