Special Filing Considerations
Fiscal Year Filers
If your business operates on a fiscal year rather than a calendar year, your filing deadlines will be based on your fiscal year end. Generally, returns are due on the 15th day of the 3rd month (partnerships) or 4th month (corporations) after the close of your fiscal year.
State Filing Deadlines
State filing deadlines often coincide with federal deadlines, but may vary by state. Some states automatically grant the same extension as federal, while others require a separate state extension request. Check with each specific state for exact requirements.
