In short
A calendar-year C corporation's return (Form 1120) is due April 15, the 15th day of the 4th month after year-end. Partnership (Form 1065) and S corporation (Form 1120-S) returns are due March 15, the 15th day of the 3rd month.
Key takeaways
- A 6-month extension is available on Form 7004.
- An extension of time to file isn't an extension of time to pay.
- Late partnership and S corporation returns carry a penalty per owner for each month late.
