Michigan marketplace facilitator rules generally put the duty to collect and remit sales tax on the facilitator for sales it handles on behalf of marketplace sellers. Michigan’s Department of Treasury defines a facilitator by what it does: it lists or advertises taxable goods or services for sellers and, for consideration, collects customer payment and transfers it to the seller. Michigan has one statewide sales tax rate and no local sales tax.
Marketplace sales do not automatically settle every seller’s Michigan obligations. A seller’s own direct sales, physical presence, and combined Michigan sales activity can affect whether it must register and file. The practical first step is to separate facilitator-handled transactions from direct sales, then check the applicable nexus rules and your assigned filing requirements.
What counts as a marketplace facilitator in Michigan?
The Michigan Department of Treasury describes a marketplace facilitator as a person that meets both parts of a test. It facilitates retail sales for marketplace sellers by listing or advertising tangible personal property or taxable services, and it directly or indirectly collects payment from the customer and transfers that payment to the seller under an agreement or arrangement, for consideration.
A marketplace seller is a person making retail sales through a physical or electronic marketplace operated by a facilitator. The label a business uses for its service is not decisive; the activities and payment arrangements matter. If your business operates a sales channel or uses a marketplace with an unusual payment flow, confirm how the Michigan definition applies before deciding who reports the tax.
Who collects and remits Michigan sales tax?
A facilitator that is required to collect Michigan tax generally reports and remits tax on the sales it facilitates. Michigan treats the facilitator as the taxpayer for facilitated sales, and the facilitator is responsible for the required registration, returns, and payment for those transactions. The facilitator’s collection duty does not, by itself, remove a seller’s obligations on separate direct sales.
Michigan’s sales tax rate is 6% statewide, with no local sales tax added by cities or counties. The rate applies to taxable sales; whether a particular product or service is taxable depends on its tax treatment under Michigan law. Keep marketplace statements and transaction records so you can distinguish sales for which the facilitator handled tax from sales your business made and must assess separately.
Michigan economic nexus rules for marketplace sellers
Michigan’s economic nexus test looks to the previous calendar year. A marketplace facilitator or marketplace seller has economic nexus with Michigan if, in the previous calendar year, it had more than $100,000 in sales to Michigan purchasers or 200 or more separate transactions with Michigan purchasers. The calculation includes taxable and nontaxable sales and transactions.
For a facilitator, the calculation includes its own direct Michigan sales and the Michigan sales it facilitates for marketplace sellers. For a marketplace seller, the calculation includes both direct sales to Michigan customers and sales made through marketplaces. The threshold is not limited to sales on which tax was collected, so do not use taxable sales alone to test it.
How direct sales affect your Michigan nexus
Direct sales matter even when most of your Michigan orders go through a marketplace. A seller’s direct Michigan sales and marketplace-facilitated sales are both included when determining whether that seller meets the economic nexus threshold. A facilitator likewise counts its own direct sales as well as the sales it facilitates.
Economic nexus is not the only possible basis for an obligation. Physical presence and other nexus circumstances can also matter. Review where inventory is stored, where business activities take place, and how orders are fulfilled; if the facts are unclear, ask the Michigan Department of Treasury or have a compliance professional review them rather than relying only on a marketplace’s tax collection.
When marketplace sellers must register in Michigan
A seller that makes only sales handled by a facilitator that is registered and remitting Michigan tax generally does not need to register solely because of those facilitated sales, and it does not report those transactions as its own taxable sales. The Michigan Department of Treasury’s marketplace guidance distinguishes those sales from a seller’s direct sales.
A seller with direct sales may need to register if it has Michigan nexus and makes taxable sales for which it is responsible. Under the economic nexus rule, activity in the previous calendar year determines whether the seller must begin reporting and paying in the following tax year. Registration is available through Michigan Treasury Online (MTO); review the Treasury’s current registration instructions and confirm your specific facts before filing.
How to report marketplace sales on Michigan returns
Do not include sales made through a marketplace facilitator on your seller return when the facilitator is responsible for collecting and remitting tax on those sales. Report your own direct sales as required if you are registered and have a filing obligation. Reconcile marketplace reports, payment statements, refunds, and your order records so facilitated transactions are not mistakenly treated as direct sales.
Michigan returns may still be required for a period with no tax due if you remain registered; the Treasury says registered taxpayers must file within their assigned frequency. Use MTO or the applicable Michigan filing method, follow the return instructions for the tax year, and retain records supporting the amounts reported and excluded. If a marketplace’s tax treatment or transaction data is incomplete, resolve the discrepancy before submitting the return.
Michigan sales tax filing and payment deadlines
The Michigan Department of Treasury assigns a monthly, quarterly, or annual filing frequency. Monthly returns and payments are generally due by the 20th of the following month; quarterly returns and payments are generally due by the 20th of the month after the quarter ends; annual returns are generally due February 28 of the following year. Treasury determines the filing frequency, so use the schedule assigned to your account rather than choosing one yourself.
Michigan requires an annual return from filers regardless of assigned frequency, subject to the applicable filing method and instructions. If a due date falls on a weekend or state holiday, the due date moves to the next business day. Check the current Treasury due-date calendar and your MTO account for your exact obligations, including any special payment requirements.
Risks of missing Michigan sales tax obligations
Failing to register, collect, report, or pay tax when required can lead to tax assessments, interest, and penalties under Michigan law. Errors can also arise when a seller assumes that a marketplace handles every transaction, overlooks direct sales, or excludes nontaxable sales from the economic nexus calculation. A facilitator’s collection on its transactions is not a substitute for reviewing the seller’s own activity.
Keep evidence of marketplace-collected tax, direct-sale records, exemption documentation, and filed returns. If you discover a gap, review the affected periods and contact the Michigan Department of Treasury or a qualified tax professional promptly. The right correction depends on the facts and the applicable procedures; do not assume that a marketplace report alone resolves a past filing issue.

Michigan marketplace sales tax: who handles the transaction and what to check
| Sales or activity | Michigan treatment and practical action |
|---|---|
| Marketplace order for which the facilitator collects and remits tax | The facilitator reports and remits tax on the facilitated sale; the seller generally does not report that sale as its own taxable sale. |
| Seller’s direct sale to a Michigan customer | Assess the seller’s own nexus and tax responsibility; report direct sales as required if registered and obligated. |
| Facilitator’s own direct sale | Count it with facilitated Michigan sales when the facilitator tests economic nexus; the facilitator handles its own applicable sales obligations. |
| Nontaxable or exempt Michigan sale | It can still count toward the economic nexus sales or transaction test; determine taxability separately from threshold counting. |
| Registered seller with no tax due for a filing period | A return may still be required within the assigned filing frequency; check the account and Treasury instructions. |
| Michigan destination sale subject to sales tax | Apply Michigan’s statewide 6% rate; Michigan has no local sales tax. |
Frequently asked questions
What is a marketplace facilitator under Michigan law?
It is a person that facilitates retail sales for marketplace sellers by listing or advertising tangible personal property or taxable services and, for consideration, directly or indirectly collects customer payment and transfers it to the seller. Both parts of the definition must be considered when classifying a business.
Do marketplace facilitators have to collect sales tax in Michigan?
A facilitator required to collect Michigan tax must collect and remit tax on the sales it facilitates and meet the related registration and filing obligations. Its own direct sales are also relevant to its tax responsibilities and nexus calculation.
What is Michigan’s economic nexus threshold for marketplace facilitators?
The threshold is more than $100,000 in Michigan sales or 200 or more separate Michigan customer transactions in the previous calendar year. The calculation includes taxable and nontaxable activity, and a facilitator includes both its direct sales and sales it facilitates.
Do marketplace sellers still need to register for Michigan sales tax?
A seller that makes only sales for which a registered facilitator collects and remits generally does not need to register solely for those facilitated sales. A seller with direct sales or another basis for Michigan nexus may have to register and report its own obligations; confirm the facts and current Treasury instructions.
Are sellers responsible for sales tax on transactions handled by a marketplace facilitator?
When the facilitator is responsible for collecting and remitting tax on a facilitated transaction, the facilitator handles that transaction’s tax reporting and payment. The seller remains responsible for reviewing its separate direct sales and other Michigan obligations, and should retain records showing which transactions the facilitator handled.
Do marketplace facilitators include direct sales when calculating Michigan nexus?
Yes. A facilitator includes its own direct Michigan sales as well as sales it facilitates for marketplace sellers when testing the economic nexus threshold. Marketplace sellers also include their direct and facilitated sales in their own threshold calculation.
What is Michigan’s marketplace facilitator sales-tax rate?
Michigan’s statewide sales tax rate is 6%, and the state has no local sales tax. The rate applies to taxable sales; product or service taxability should be checked separately.
