||How to File
No Physical Form
Taxpayers are required to submit a LA state extension electronically via the Louisiana Department of Revenue website on or before the May 15, 2018 return deadline. Louisiana no longer recognizes an extension granted by the Internal Revenue Service.
An extension only extends the time to file the return, not the time to pay any tax that may be due. To submit a payment if you're efiling an extension, you can use Form R-2868V, Electronically Filed Extension Payment Voucher. Payments received after May 15, 2018 will be charged late payment and interest penalties.
If you are expected to make LA state estimated payments, pay by check or money order by using Form IT-540ES, Louisiana Estimated Tax Declaration Voucher for Individuals.
Complete and submit online extension via LA state tax agency website

LA Sales Tax Holiday:
Louisiana holds three annual sales tax holidays. During these holidays, certain items are exempt from Louisiana sales tax.
Refer to the chart below for all Louisiana sales tax holidays for 2018.
|Sales Tax Holiday Dates
||Sales Tax Holiday Items Included
- Emergency supplies (i.e. batteries, flashlights, chargers, food storage coolers) and other hurricane preparation items: $1,500 or less
- All tangible personal property selling up to $2,500
Note: Vehicles, prepared food items, and items to be used for a business, profession, or trade are NOT exempt from the LA sales tax.
- Firearms, ammunition and hunting supplies (i.e. apparel, binoculars, boots, all-terrain vehicles)
LA Personal Property Tax:
Property taxes are assessed and collected at the local level, not by the LA Department of Revenue.
The state offers a homestead exemption on the first $7,500 of the value of a person's main residence, but it usually does not apply to local government taxes.
Odd Tax Fact:
Louisiana has a breastfeeding sales tax exemption. Among the items included in the exemption are breast pumps and accessories, breast pump replacement parts, storage bags and accessories, and nursing bras.
However, items specifically used by the mother for comfort and convenience, rather than the act of breastfeeding itself, are subject to sales tax. These items include nursing pads, pillows, covers, stools, and bottles/bottle accessories.
