Frequently Asked Questions
How do I make a payment with my request for an extension to file a Louisiana Corporation Income and Franchise taxes return?
An electronic payment can be made through tax preparation software that supports the option, through LaTap; or by credit card at Officialpayments.com. If you need to mail in a check or money order, you must use the Electronically Filed Extension Payment Voucher, Form CIFT-620Ext-V. This voucher can be printed through the Online Extension Filing application or the Online Payment Voucher application and mailed to Post Office Box 751, Baton Rouge, LA 70821-0751.
