How do I request an extension to file a Louisiana Corporation Income and Franchise taxes return?


Corporate taxpayers who need additional time to file their Louisiana corporation income and franchise taxes returns do not need to file for an extension. You will automatically be granted an extension of six months IF you timely requested an extension for federal income tax purposes. No paper or electronic extension form needs to be filed to obtain the automatic extension. You will need to mark the box on Form CIFT-620 indicating that you timely requested an extension for federal income tax purposes in order to receive the extension. This is only an extension to file and NOT an extension of time to pay the tax due. (Answer revised November 6, 2023)
