Here's a rundown of the dates you'll need to keep in mind:
- Personal taxes (Form 1040) -- If you filed an extension, you've got until October 15 to file your return. Don't wait any longer than that. If you're eligible for an economic stimulus check, you can only get it if you meet the October 15 deadline. You won't get a check if you file after October 15.
- Sole Proprietorship (Schedule C) -- If you file your business taxes as a sole proprietorship, you'll be filing a schedule C with your Form 1040, and therefore will also be subject to the October 15 deadline.
- Partnerships and LLCs (Form 1065) -- You have until October 15 to file if you sent in an extension.
- Corporations (Form 1120) - You have until September 15 to file if you sent in an extension.
