How do I know which extension form I need to file?
The type of extension form that you need to file depends on the type of form that you normally file your income tax returns on with the IRS. For example, if you need an extension for your personal taxes that you normally file on form 1040-EZ you will need to file a personal extension via IRS Form 4868. Most business extensions are filed via Form 7004 and exempt organizations extensions are filed via Form 8868.
