General Instructions
Choose your state from the list below to access detailed instructions for both business and personal tax extensions.
Corporate tax returns are due by April 15 — or by the 15th day of the 4th month following the end of the taxable year (for fiscal year filers).
Louisiana offers a 7-month extension, which moves the filing deadline to November 15 (for calendar year filers).
The Louisiana Department of Revenue does not accept paper requests for tax extensions. You must request a Louisiana extension electronically using the Online Extension Filing system: esweb.revenue.louisiana.gov/OnlineTaxExtensions
An extension of time to file is not an extension of time to pay. If you owe Louisiana tax, your balance must be paid by the original due date to avoid penalties. You can make a Louisiana extension payment with Form CIFT-620EXT-V, or pay electronically via Online Extension Filing: esweb.revenue.louisiana.gov/OnlineTaxExtensions
Online payment vouchers can be printed out at the Louisiana Department of Revenue website: esweb.revenue.louisiana.gov/OnlineVouchers
