Economic nexus threshold

You must register and collect once your Mississippi sales reach $250,000, measured over the preceding 12 months. There is no transaction-count threshold. Sales made through a marketplace facilitator do not count toward the remote seller's threshold — only your direct sales do.

Marketplace facilitator rules

Since July 2020, marketplace facilitators (Amazon, eBay, Walmart, TikTok Shop) collect and remit Mississippi tax on your marketplace sales. How Mississippi treats them:

Who collects?Facilitatoron marketplace orders; you collect on Shopify / your own site.

Count toward nexus?Noonly your direct sales are tested against the remote-seller threshold.

Do you still file?YesYes — a registered seller still files, even for periods where all sales were through marketplaces (a zero or marketplace-only return).

How reported?Not reportedNot reported — report direct sales only.

Direct salesYou collectShopify, your own site, invoices — you collect and remit on your return.

Marketplace treatment changes state by state and year by year — SalesTax50 separates marketplace and direct sales automatically, but confirm with Mississippi Dept. of Revenue when in doubt.

Filing portal & AutoFile

Mississippi returns are filed through tap.dor.ms.gov/_. Login verification: May require verification. SalesTax50 AutoFile prepares the Use Tax Return from your imported sales — you review and approve every return before it is submitted.

FAQ

Do I need a Mississippi permit if I only sell on Amazon?

If you exceed the $250,000 threshold with your direct (non-marketplace) sales or have physical presence (including inventory in Mississippi warehouses), yes — you must register even though Amazon collects for you.

What if I sell on Shopify and TikTok Shop?

TikTok Shop collects as a marketplace facilitator; Shopify does not. You collect on Shopify orders and report both streams on your Mississippi TAP return — SalesTax50 separates them automatically.

Does SalesTax50 file Mississippi returns automatically?

Yes — AutoFile prepares your Use Tax Return from imported sales; you approve every return before it is submitted, and a $99 one-time state setup configures your existing Mississippi permit.

Marketplace sales?

Mississippi excludes marketplace-facilitated sales from the remote seller's return; report direct sales only.
