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, TikTok Shop) collect and remit Michigan tax on your marketplace sales. How Michigan treats them:

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

Does SalesTax50 file Michigan returns automatically?

Yes — AutoFile prepares your Form 5080 from imported sales; you approve every return before it is submitted, and a $99 one-time state setup configures your existing Michigan permit.
