Louisiana Requires Electronic Filing and Payment for Most Sales Tax Returns Starting January 2026

• Louisiana will require electronic filing and payment for almost all sales and use tax returns starting January 1, 2026.

• The mandate affects remote sellers, ecommerce brands, and anyone filing Form R-1029 or paying Louisiana sales tax by check.
• Sellers must ensure their systems are set up for electronic filing and payment using approved platforms before the deadline.
