Mississippi taxes through the Mississippi Department of Revenue at a 7% statewide base rate, with local rates stacking on top and economic nexus for remote sellers at $250,000 in sales. Filing runs monthly or quarterly by liability. For e-commerce & online sellers, that combination is what decides how much of your month-end is bookkeeping and how much is compliance.
Employer registration runs through the Mississippi Department of Employment Security, and the entity is registered with the Mississippi Secretary of State. High state rate with very little local layering, and a higher threshold than most states.

Sales tax nexus in Mississippi
Economic nexus in Mississippi is $250,000 in sales. For e-commerce & online sellers, that threshold is the one to watch, because it is reached by selling into the state — no office, no staff, no physical presence required. Once you cross it you are expected to register with the Mississippi Department of Revenue and begin collecting. We track your Mississippi sales against it and tell you before you cross, not after.
Marketplace sales vs. your own channels in Mississippi
Marketplace facilitator rules mean large platforms generally collect and remit Mississippi tax on sales made through them. Your own site, wholesale, and direct sales are a different matter — those remain yours to collect and report. Keeping the two streams separate in the books is what makes the Mississippi Department of Revenue return match reality.
Mississippi rates and sourcing
The Mississippi statewide base rate is 7%. Local rates stack on top and are generally sourced to the delivery address, so the effective rate varies within the state. Getting sourcing right is what keeps the liability account matching what you actually collected.
Filing cadence in Mississippi
Mississippi assigns filing frequency by liability — monthly or quarterly by liability. Mississippi does not offer an annual bracket, so even low-volume sellers file at least quarterly and the account has to stay current year-round.
