Mississippi Sales Tax Economic Nexus Threshold (2026)

Mississippi's economic nexus threshold, in detail

The current Mississippi threshold is $250,000, in effect since 2018-07-01.

What counts toward the threshold: gross sales of tangible personal property AND most services delivered to Mississippi customers. Resale sales may count in some states. Marketplace-facilitated sales typically do NOT count. Check the state's specific definitions before computing.

Counting periods

Most states apply the threshold on a rolling 12-month basis — look at the prior 12 months as of the end of each month. Some states look at the prior calendar year specifically. Mississippi's rule is stated in its regulations; your registration must begin no later than the first day of the month after you cross, unless the state allows a grace period.

Common threshold-tracking mistakes

Measuring by calendar year only, missing when a rolling 12-month window would have triggered earlier.
Including tax in “gross sales”. The threshold uses pre-tax revenue; double-counting tax in the threshold figure can prematurely trigger registration.
Forgetting that the threshold resets — falling below in a subsequent year doesn't automatically deregister you. You must request deregistration through the Mississippi DOR.

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.
