Retailer Tax Fairness Act; create.

HB 606, the Retailer Tax Fairness Act, allows Mississippi retailers to reduce their state and local sales tax bills by 2.5% for transactions where they pay credit or debit card processing fees (interchange fees). It applies to all electronic payments (credit/debit cards) where merchants incur these fees to card networks. The credit covers taxes collected under specific state sales tax codes and local taxes on hotels, motels, and restaurants. The law takes effect on July 1, 2026.
