Which state is easier for sellers?

For low-revenue sellers: nexus triggers first in both states because of its threshold. If you cross that first, you register there first.

On rate: Mississippi is friendlier for customers with a combined state + local rate of 7.07% vs 9.46%.

Neither state has a transaction-count trigger — only the dollar threshold matters.

Alabama — nexus note

Economic nexus in Alabama triggers at $250,000 in gross sales delivered into Alabama in the current or prior calendar year. No transaction count threshold.

Mississippi — nexus note

Mississippi sales and use tax nexus threshold: out-of-state businesses with Mississippi sales exceeding $250,000 over any twelve-month period are considered to have substantial economic presence effective July 1, 2018 and must register, collect, and remit tax. Mississippi uses a sales-only threshold — no transaction-count test. Remote sellers should measure sales on a rolling twelve-month basis rather than the current-or-prior-calendar-year framing used by many other states.

Frequently asked questions

Which state has the lower sales tax nexus threshold, Alabama or Mississippi?
Both Alabama and Mississippi publish the same economic nexus dollar threshold of $250,000, so a remote seller would reach each state's published threshold at the same level of in-state sales. These are the thresholds published by each state's tax authority as of 2026-05-15; confirm against the official source before registering.
Do both Alabama and Mississippi have marketplace facilitator laws?
Yes. Both Alabama and Mississippi have marketplace facilitator laws, so marketplaces such as Amazon, Etsy, and eBay collect and remit sales tax on the sales they facilitate in both states. Direct-to-consumer sales you make outside a marketplace remain your own responsibility once you cross each state's threshold. Verified 2026-05-15.
Which has the lower sales tax rate, Alabama or Mississippi?
Mississippi has the lower combined state and local sales tax rate at 7.07%, compared with 9.46% in Alabama. These are the statewide base rate plus the average local rate; the exact rate depends on the customer's delivery address. As of 2026-05-15.
Do I need to register for sales tax in both Alabama and Mississippi?
It depends on where you cross each state's economic nexus threshold (or have physical presence there). Alabama's published threshold is $250,000, and Mississippi's is $250,000. You generally register in a state only once you cross its threshold, so you may have an obligation in one, both, or neither. Run the nexus calculator with your actual sales and confirm with each state's official source. Thresholds as of 2026-05-15.
When did economic nexus take effect in Alabama and Mississippi?
Alabama's economic nexus rule took effect on 2018-10-01, and Mississippi's took effect on 2018-07-01. Both stem from the 2018 South Dakota v. Wayfair Supreme Court decision, which let states require remote sellers to collect once an economic threshold is met.
