TaxAct® supports the completion of Form 4868 Automatic Extension of Time to File U.S. Income Tax Return for your federal return, as well as any necessary extension forms for your state, if applicable. Form 4868 must be filed by the regular due date of the return.
Please Note: Filing an extension ONLY extends the time to file your return and does not extend the time to pay any tax due. To avoid late payment penalties and interest you must estimate what tax will be due and pay that when you file the extension form.
