Michigan generally uses a statewide sales and use tax rate with no local sales tax add-ons.
Remote sellers should monitor Michigan sales against the economic nexus threshold.
Michigan also uses a transaction-count threshold for remote-seller nexus.
Quick answer for ecommerce sellers.
If you sell taxable goods or taxable services into Michigan, you may need to register, collect, file, and remit Michigan sales and use tax if you have Michigan physical presence or meet Michigan economic nexus rules. Michigan generally uses a $100,000 sales threshold or 200 separate transactions in the previous calendar year for remote sellers.
The practical work is to separate direct ecommerce orders from marketplace orders, confirm taxability, reconcile tax collected, and save filing confirmations from Michigan Treasury Online with the source reports.
What creates Michigan sales tax nexus?
Michigan nexus can come from physical presence or economic activity. Physical presence may include inventory, employees, contractors, offices, warehouses, or other Michigan operations. Economic nexus can apply even when a seller has no Michigan location.
- Physical presence: inventory, facilities, employees, agents, or business operations in Michigan can create obligations.
- Economic nexus: monitor Michigan sales against the $100,000 or 200 transaction framework.
- Marketplace activity: marketplace facilitator sales should be separated from direct sales for reporting and reconciliation.
For a multi-channel seller, a Michigan nexus review should start with channel-level reporting: direct store orders, Amazon, Walmart, Etsy, eBay, wholesale, refunds, exempt sales, taxable sales, and tax collected.
How Michigan registration fits into the workflow.
Michigan sellers commonly use Michigan Treasury Online, or MTO, for registration, filing, payment, and account management. Before registration, confirm the legal entity, EIN, business address, responsible party, sales start date, product categories, payment method, and account owner.
After the account is active, save the sales tax account information, filing frequency, login owner, payment setup, and return schedule in the same workspace as the filing packet. This makes handoffs and review much easier.
Collection, taxability, and marketplace sales.
Michigan generally has a 6% statewide sales tax rate, so sellers do not have to manage local sales tax rate variation. That does not eliminate taxability work. Groceries for home consumption, prescription medications, certain medical items, resale transactions, and manufacturing or agricultural exemptions may require separate treatment.
- Direct ecommerce sales: orders where the merchant is seller of record and may need to collect Michigan tax.
- Marketplace sales: marketplace-facilitated orders should be isolated because the marketplace may collect tax.
- Exempt or resale sales: exemption certificates and resale support should be retained with the filing packet.
- Refunds and shipping: period reports should preserve refunds, discounts, and delivery details for reconciliation.
How to prepare a Michigan sales tax filing packet.
The Michigan filing packet should let a reviewer trace every return number back to source data. A statewide rate helps, but the return still needs clean sales categories, marketplace treatment, and payment proof.
- Export exact-period reports: pull orders, refunds, tax, marketplace collection, and exemption data for the filing period.
- Separate channels: split direct website orders from marketplace-facilitated orders.
- Map sales types: identify gross sales, taxable sales, exempt sales, resale sales, returns, and tax collected.
- Reconcile to accounting: compare platform tax, payment processor summaries, payouts, and bookkeeping totals.
- Prepare the return summary: document filing period, gross sales, deductions, taxable sales, tax due, reviewer, and payment amount.
- Save proof: keep the MTO confirmation, payment receipt, source exports, and review notes together.
Michigan monthly and quarterly filings are commonly due on the 20th day after the reporting period, while annual filing can follow a different schedule. Follow the frequency assigned in the account.
What happens if Michigan filings are late or unsupported?
Late filings, late payments, unsupported exempt sales, marketplace blending, and weak documentation can create notices, penalties, interest, and audit work. The return should be easy to recreate from saved workpapers.
Before filing, review this checklist:
- Does the period match every source export?
- Are marketplace-collected orders separated from direct sales?
- Are exemption and resale records saved?
- Do refunds and tax collected reconcile to accounting?
- Was the MTO confirmation and payment receipt saved?
