Michigan Sales Tax and Invoicing Rules for 2026

State sales tax rate

Michigan levies a 6% state sales tax with no local sales tax additions. The rate is a uniform 6% everywhere in the state — Detroit, Grand Rapids, Ann Arbor, and rural areas all charge the same rate.

This simplicity makes Michigan one of the easiest states for sales tax compliance. Michigan uses destination-based sourcing for determining where a sale takes place, but since there are no local rate variations, the practical impact is minimal for rate calculation.

Nexus rules

Physical nexus is triggered by having a place of business, employees, inventory, or property in Michigan. This includes inventory stored in Michigan fulfillment centers or warehouses.

Economic nexus applies when you exceed $100,000 in gross sales OR 200 or more transactions delivered into Michigan in the prior calendar year. Either threshold creates nexus.

Marketplace facilitators are required to collect and remit sales tax on behalf of third-party sellers. Michigan is a member of the Streamlined Sales Tax agreement, and out-of-state sellers can register through the SST system.

Invoice requirements

The Michigan Department of Treasury requires sellers to maintain records of all taxable and exempt transactions. Invoices should include:

• Seller's name, address, and sales tax license number
• Date of transaction
• Buyer information
• Description of goods or services sold
• Quantity and selling price
• Tax amount (shown as a separate line)
• Total amount due

For exempt sales, retain the buyer's Michigan Sales and Use Tax Certificate of Exemption (Form 3372). Records must be kept for at least four years from the date the tax was due or paid.

Exemptions and special cases

Food for home consumption (groceries) is exempt from sales tax. Prescription drugs are exempt. Agricultural products and farm equipment used in farming operations are exempt.

Industrial processing equipment used in manufacturing qualifies for an industrial processing exemption. Clothing is fully taxable in Michigan.

SaaS is generally not taxable — Michigan taxes tangible personal property and specifically enumerated services. Cloud-based software accessed without downloading is typically not taxable, though prewritten software delivered electronically may be. Michigan taxes a limited number of services including telecommunications.

Filing frequency and deadlines

Michigan assigns filing frequency:

• Monthly — annual liability over $3,600
• Quarterly — liability between $750 and $3,600
• Annually — liability under $750

Monthly returns are due the 20th of the following month. Quarterly returns are due the 20th of the month following the quarter. Annual returns are due February 28.

Michigan offers a vendor discount of 0.75% of the tax due for timely payment (verify current legislative status). Electronic filing is available through Michigan Treasury Online (MTO).

Penalties for non-compliance

Late filing incurs a penalty of 5% of the tax due if filed within two months of the due date, plus 5% additional for each additional two-month period (up to 25%).

Interest runs at 1% above the prime rate, adjusted annually. Failure to file can lead to estimated assessments by the Department. Willful evasion carries criminal penalties. Michigan participates in multi-state audit sharing through the SST framework.

FAQ

Is the sales tax rate really the same everywhere in Michigan?

Yes. Michigan has a flat 6% rate statewide with no local additions. This is unusual — most states allow local jurisdictions to add their own sales tax. It makes compliance significantly simpler for businesses selling in Michigan.

Are digital downloads taxable in Michigan?

Prewritten (canned) software delivered electronically is generally taxable. However, SaaS and cloud-based software accessed via browser are typically not taxable. Digital music, e-books, and streaming are not specifically taxed under current Michigan law, though this area is evolving.

Can I register for Michigan sales tax through the Streamlined Sales Tax system?

Yes. Michigan is a full member of the SSUTA. You can register through the Streamlined Sales Tax Registration System (SSTRS) to simplify registration in Michigan and other member states simultaneously.

Step-by-step: register and start collecting in Michigan

1. Confirm nexus — physical presence (Detroit-area warehouse, employees, offices) creates immediate nexus. Economic nexus: $100,000 in gross sales OR 200 transactions to Michigan buyers in the prior or current calendar year.
2. Register via Michigan Treasury Online — apply for sales tax registration through the MI Department of Treasury portal. Processing is typically 5 business days at no fee.
3. Configure flat 6% rate — Michigan has no local sales taxes; the rate is a flat 6% statewide for most goods. Michigan's simplicity for tax engines is a meaningful operational benefit.
4. Capture Form 3372 exemption certificates — Form 3372 (Michigan Sales and Use Tax Certificate of Exemption) covers most categories; Form 3520 for nonprofits. Hold certificates 4 years post-transaction.
5. File via Michigan Treasury Online — frequency varies (monthly $1,200+/year, quarterly $750–$1,200, annually under $750). Most sellers file monthly. Returns due the 20th of the following month.

Real Michigan compliance situations

• A Detroit-based SaaS provider confirmed Michigan does NOT tax SaaS as of 2026 (a useful exemption). However, when bundling software with hardware (e.g., delivering tablets pre-loaded with software), the entire bundle becomes taxable. They split sales into separate invoices when possible.
• A Grand Rapids e-commerce store ships statewide. The flat 6% rate keeps their tax engine simple — no ZIP-based logic needed for sales tax (though they still verify every order's ship-to address for use-tax purposes on out-of-state sales).
• An Ann Arbor restaurant charges 6% on prepared food. Unprepared groceries are exempt. Prescription drugs and most medical supplies are exempt. Vending machine sales of food and beverages are taxable. They itemize every receipt to align with these rules.
