If I file an extension, when do I have to file?

An extension is for 6 months from the original due date. Because taxes are generally due April 15th of each year, an extension allows you to delay filing until October 15th. But the thing to consider is whether you will owe money or not. If you file an extension and end up owing money to the IRS, you will have interest added to the tax due.
