Economic nexus threshold

You must register and collect once your Michigan sales reach $100,000 or 200 orders, measured over the previous calendar year. Meeting either the sales or the order-count test triggers nexus. Marketplace sales count toward this threshold even though the marketplace collects for you.

Filing frequency

Michigan Treasury (MTO) assigns a filing frequency at registration based on expected tax liability and adjusts it over time. Frequencies used in Michigan: Monthly · Quarterly · Annual.

Due dates

Returns are due on the 20th of the month following the period. When the due date falls on a weekend or holiday it moves to the next business day.

Late filing: 5% of tax due for the first two months, then 5% per month up to 25%, plus interest.

Marketplace facilitator rules

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

Who collects?Facilitatoron marketplace orders; you collect on direct Shopify store orders (not TikTok / Facebook & Instagram orders routed through Shopify), WooCommerce, or your own site.

Count toward nexus?Yesmarketplace + direct sales together determine your threshold status.

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?DeductionReported as a deduction / exempt line, not omitted.

Direct salesYou collectdirect Shopify store orders, WooCommerce, 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 Michigan Dept. of Treasury when in doubt.

FAQ

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

If you exceed the $100,000 or 200 orders threshold or have physical presence (including inventory in Michigan 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 Michigan Treasury (MTO) return — SalesTax50 separates them automatically.

What about WooCommerce and Etsy?

Same split: Etsy collects as a marketplace facilitator; WooCommerce is your own store, so you collect on WooCommerce orders. Connect both and SalesTax50 keeps the marketplace and direct streams separate on your Michigan Treasury (MTO) return.

Does SalesTax50 file Michigan returns automatically?

Yes — AutoFile prepares your Form 5080 from imported sales; you approve every return before it is submitted, and setting up your existing Michigan permit is included at no extra charge.
