The State of Louisiana will automatically grant you a 6 month business income tax extension if you were granted a federal extension. However, you will need to submit Louisiana tax payment voucher Form 620EXT (PDF) if you need to make a state tax payment. If you do not need to make a tax payment and have received an approval notification from FileLater, there’s nothing more to do. Please be sure to attach printed a copy of your FileLater tax extension form when you submit your tax return.

Filing for a Louisiana tax extension will not provide you with additional time to pay any tax balance due, which must be paid by your business income tax deadline or interest and other payment penalties may apply.

For additional information, please visit the State of Louisiana Department of Revenue website.
