Michigan Economic Nexus Requirements for Remote Sellers 2026

If you’re a remote seller doing business in Michigan, understanding the state’s economic nexus requirements is essential for maintaining compliance and avoiding costly penalties. Following the South Dakota v. Wayfair Supreme Court decision, Michigan implemented economic nexus laws that affect businesses selling into the state, even without a physical presence. This comprehensive guide covers everything remote sellers need to know about Michigan’s economic nexus requirements for 2026.

What Is Economic Nexus in Michigan?

Economic nexus refers to the connection between a business and a state that creates a sales tax collection obligation based on economic activity rather than physical presence. Before 2018, businesses only needed to collect sales tax in states where they had a physical presence—such as an office, warehouse, or employees. The landmark Wayfair ruling changed everything, allowing states to require remote sellers to collect sales tax based on their sales volume or transaction count.

Michigan adopted economic nexus legislation effective October 1, 2018, requiring remote sellers meeting specific thresholds to register for sales tax and begin collecting and remitting taxes on taxable sales to Michigan customers.

Michigan Economic Nexus Threshold for 2026

For 2026, Michigan maintains the same economic nexus thresholds established when the law was first enacted:

$100,000 in gross sales of tangible personal property to Michigan customers in the previous calendar year, OR
200 or more separate transactions of tangible personal property to Michigan customers in the previous calendar year

Meeting either threshold creates an economic nexus obligation. It’s important to note that these thresholds are evaluated on a calendar year basis, meaning you must monitor your Michigan sales activity throughout the year to determine if you’ve triggered nexus.

What Sales Count Toward the Economic Nexus Threshold?

When calculating whether you’ve met Michigan’s economic nexus threshold, the following sales are included:

Retail sales of tangible personal property shipped to Michigan
Sales made through marketplace facilitators (count toward your threshold even if the marketplace collects the tax)
Wholesale sales (though these may not be taxable, they count toward the threshold)
Exempt sales (such as sales to exempt organizations)

However, it’s important to understand that while all these sales count toward your nexus determination, you are only required to collect sales tax on taxable retail sales to Michigan customers.

When Must Remote Sellers Register for Michigan Sales Tax?

Once you determine that you’ve met Michigan’s economic nexus threshold, you have specific obligations:

Registration Timeline

Remote sellers must register for a Michigan sales tax license by the first day of the month that is three months after the month in which the threshold was met. For example, if you exceed the threshold in March 2026, you must register by July 1, 2026.

This grace period gives businesses time to set up their tax collection systems, but it’s crucial not to delay. Registration can be completed through the Michigan Department of Treasury’s online portal, Michigan Treasury Online (MTO).

Ongoing Monitoring Requirements

Even if you don’t meet the threshold in the current year, you must continue monitoring your Michigan sales activity. If your sales fall below the threshold in a subsequent year, you may request to cancel your registration, but you must continue filing returns until the cancellation is approved.

Michigan Sales Tax Collection Requirements

Once registered, remote sellers must collect Michigan sales tax on all taxable sales to customers in the state. Michigan’s state sales tax rate is 6%, and there are no local sales taxes, making compliance relatively straightforward compared to states with complex local tax structures.

Taxable Items

Most tangible personal property sold to Michigan customers is subject to sales tax. Common taxable items include:

Clothing and footwear
Electronics and appliances
Furniture and home goods
Books, magazines, and printed materials
Software delivered on tangible media (CDs, DVDs)

Exempt Items

Certain items are exempt from Michigan sales tax, including:

Prescription drugs and medical devices
Food for human consumption (excluding prepared foods)
Newspapers and periodicals
Certain agricultural products

For a complete list of taxable and exempt items, consult Michigan’s sales tax guidelines or speak with a tax professional.

Marketplace Facilitator Rules in Michigan

Michigan enacted marketplace facilitator legislation effective January 1, 2020. Under these rules:

Marketplace facilitators (such as Amazon, eBay, and Etsy) are responsible for collecting and remitting sales tax on behalf of third-party sellers
If a marketplace collects tax on your sales, you do not need to collect tax on those specific transactions
However, marketplace sales still count toward your economic nexus threshold
You must still register and file returns if you meet the threshold, even if all your sales are through marketplaces that collect tax

This creates a situation where you may be required to register and file returns even if you have no tax to remit. For guidance on managing marketplace sales, visit State Sales Tax Resources.

Filing and Remittance Requirements

Once registered, remote sellers must file Michigan sales tax returns according to their assigned filing frequency:

Filing Frequencies

Monthly: Required if monthly tax liability exceeds $100
Quarterly: Required if annual tax liability is between $300 and $1,200
Annual: Required if annual tax liability is less than $300
Accelerated: Required for very large retailers with significant monthly liabilities

Due Dates

Monthly returns: Due on the 20th of the following month
Quarterly returns: Due on the 20th of the month following the quarter end
Annual returns: Due February 28 of the following year

Returns must be filed electronically through Michigan Treasury Online (MTO). Even if you have no sales or tax to report, you must file a zero return to remain in compliance.

Penalties for Non-Compliance

Failing to comply with Michigan’s economic nexus requirements can result in significant penalties:

Late Registration: Penalties may apply for failing to register when required
Late Filing: 5% penalty per month (maximum 25%) of unpaid tax
Late Payment: Penalty and interest on unpaid tax balances
Failure to Collect: You may be held liable for tax that should have been collected, plus penalties and interest

The Michigan Department of Treasury has increased enforcement efforts for remote sellers, making compliance more important than ever.

Record Keeping Requirements

Michigan requires businesses to maintain detailed sales records for at least four years. Remote sellers should keep:

Sales invoices and receipts
Shipping documentation showing delivery locations
Exemption certificates for tax-exempt sales
Marketplace sales reports
Tax returns and payment records

Good record-keeping not only ensures compliance but also makes it easier to respond to any audits or inquiries from the state.

Steps to Ensure Compliance in 2026

To stay compliant with Michigan’s economic nexus requirements, remote sellers should take the following steps:

Monitor Your Sales: Track your Michigan sales volume and transaction count monthly to identify when you approach the threshold
Register Promptly: Once you meet the threshold, register within the required timeframe
Configure Tax Settings: Update your e-commerce platform to collect Michigan sales tax at the correct rate
File Returns: Submit returns on time, even if you have no tax to remit
Stay Informed: Monitor tax law changes that may affect your obligations

Conclusion

Michigan’s economic nexus requirements for remote sellers remain consistent in 2026, with the $100,000 sales or 200 transaction threshold determining your obligation to collect and remit sales tax. While Michigan’s flat 6% state rate simplifies collection compared to states with complex local tax structures, compliance still requires careful monitoring of your sales activity and timely registration and filing.

Remote sellers should implement systems to track sales by state, understand their nexus obligations, and maintain proper records. For businesses selling across multiple states, tools like StatesSalesTax.com can help monitor nexus thresholds and simplify compliance.

If you’re uncertain about your Michigan economic nexus status or need assistance with registration and compliance, consider consulting with a tax professional who specializes in multi-state sales tax. The cost of professional guidance is far less than the potential penalties for non-compliance.
