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.

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.

Alabama — nexus note

Alabama sales/use tax nexus and economic nexus threshold: out-of-state sellers and marketplace facilitators with more than $250,000 in retail sales into Alabama during the previous calendar year must collect Alabama tax, and remote sellers may participate in the Simplified Sellers Use Tax (SSUT) program — a flat 8% sellers use tax on sales delivered into Alabama (Rule 810-6-2-.90.03; SSUT under Act 2015-448). Alabama uses a sales-only threshold — no transaction-count test. The $250,000 calculation counts only the seller's own retail sales; it excludes wholesale sales for resale and any sales made through an SSUT-participating marketplace that already collects Alabama tax. Marketplace facilitators meeting the $250,000 threshold have collected and remitted SSUT on facilitated Alabama sales (or complied with notice/reporting under §40-23-199.2) since January 1, 2019. If you exceed $250,000 in a calendar year, collection begins January 1 of the following year. SSUT participants may deduct a 2% timely-filing discount, capped at $8,000 per month. Alabama Department of Revenue source data last retrieved 2026-06-14.

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.
