A federal income tax filing extension also acts as an extension of time to file your City tax return. You do not need to submit a copy of the extension by the annual filing due date. When you file your City tax return, please attach a copy of your extension to potentially avoid a late filing penalty. If you have not requested or received a federal extension, you may receive a six-month extension for filing your City tax return by submitting Form 32-EXT to RITA on or before the annual filing due date. This form is available at the RITA website. Remember: An extension to file the annual return is not an extension to pay - the tax owed is still due by the annual filing due date.
