• Mississippi’s regular retail sales tax rate is 7%. Groceries dropped to 5% on July 1, 2025. Local add-ons exist only at the city level: Tupelo adds 0.25% and Jackson adds 1% on certain sales. A sales tax permit from the Department of Revenue is required before doing business, one per location. Mississippi Department of Revenue

This is general information, not legal advice. Your county, your city hall or an attorney can confirm what applies to you.
