The Great Lakes State offers a robust and stable tax environment for businesses, particularly those in the manufacturing and technology sectors. For startups and international founders, Michigan corporate state taxes provide a clear and straightforward fiscal framework with a flat corporate rate and significant tax advantages for digital service providers, including the exemption of Software as a Service (SaaS) from state sales tax.
Key Takeaways
- Flat Corporate Rate: Michigan imposes a flat 6.0% corporate income tax.
- SaaS is Exempt: Software as a Service (SaaS) is generally not subject to Michigan sales tax when accessed remotely.
- Streamlined Sales Tax: Michigan is a member of the Streamlined Sales Tax (SST) initiative, simplifying multi-state compliance.
- Economic Nexus: Remote sellers trigger sales tax obligations if they exceed $100,000 in annual gross sales or 200 separate transactions in Michigan.
If I Want To Open A Business In Michigan, What Will I Have To Do?
Starting a business in Michigan begins with registering your legal entity through the Michigan Department of Licensing and Regulatory Affairs (LARA). Once your entity is formed, you must register for state tax accounts with the Michigan Department of Treasury using the Michigan Treasury Online (MTO) portal.
Most businesses will need to register for sales tax, corporate income tax, and employer withholding if they plan to hire staff. For international entrepreneurs navigating these steps, understanding how state taxes work for foreign-owned businesses is a vital first step in ensuring long-term compliance.
Does Michigan Have an Income Tax?
Yes. Michigan imposes a corporate income tax on the Michigan-apportioned net income of C-Corporations. As of 2026, the rate is a flat 6.0%. Michigan uses a single-sales factor apportionment formula, which is generally beneficial for companies that have significant operations or assets outside the state but sell into the Michigan market.
Does Michigan Have a Franchise Tax?
No. Michigan has replaced its previous business tax structures with a simpler corporate income tax. There is no general corporate franchise tax on net worth or capital stock for most businesses. This simplification reduces the fixed overhead for corporations maintaining a presence in the state, making the Michigan corporate state taxes landscape more predictable for high-growth companies. This is a notable contrast to states like Vermont, which still utilize graduated rates.
What Triggers Corporate Income Tax Nexus in Michigan?
Nexus in Michigan is established when a business has a sufficient connection to the state to justify taxation.
- Physical Presence: Having an office, warehouse, or retail location in Michigan. Storing inventory in a third-party fulfillment center (like Amazon FBA) within Michigan also creates physical nexus.
- Employee Nexus: Having one or more employees working in Michigan, including remote staff working from home offices, generally triggers a filing requirement.
- Economic Nexus: Michigan follows a “doing business” standard for income tax. While it does not have a specific bright-line dollar threshold for income tax as strict as its sales tax rules, any company deriving significant income from Michigan sources is generally considered to have nexus.
Does Having a Mailing Address in Michigan Trigger Corporate Income Tax or Registration?
Generally, a mere mailing address or the use of a registered agent service in Michigan does not trigger corporate income tax nexus. However, if that address is used as a base of operations for management or if it serves as a location where business decisions are made, the state may argue that the business is “domiciled” in Michigan and subject to tax.
If I Have My Business in Michigan but Live in a Different State, Will I Pay Tax?
Yes. If your business has nexus in Michigan, the income it generates from Michigan sources is subject to state tax. For pass-through entities like S-Corporations or LLCs, the income flows through to the owners. Non-resident owners are typically required to file a Michigan non-resident individual return to pay tax on their share of the Michigan income. You can find more details in our guide to filing for disregarded entities.
If All My Activities Are Outside the U.S. and I Live Abroad, But Have a Company in Michigan, Do I Have to Pay Tax?
Yes. A Michigan-incorporated C-Corporation is a domestic entity and is required to file and pay the 6.0% tax on its apportioned income. If you operate a foreign-owned LLC, you may not owe state-level income tax if the business has no “effectively connected income” in the state, but you must still satisfy federal IRS requirements and may have state informational filing duties.
Does Having an Employee in Michigan Trigger Corporate Income Tax?
Yes. Michigan considers the presence of a single employee performing services or soliciting orders within the state as a significant physical presence. This triggers both corporate income tax nexus and the requirement for the employer to withhold Michigan state income taxes from the employee’s wages.
Does Having an Independent Contractor in Michigan Trigger Corporate Income Tax?
It depends on the nature of their work. If an independent contractor is soliciting sales or performing essential business functions that help establish and maintain a market in Michigan, the Department of Treasury may determine that the company has nexus.
Does Having a Founder Living in Michigan Trigger Corporate Income Tax?
Typically, yes. If a founder or executive resides in Michigan and performs management duties or directs the operations of the company from their home, the company is considered to be “doing business” in Michigan.
If You Hold Board Meetings in Michigan, Will It Trigger Corporate Income Tax?
Holding board meetings in Michigan is a corporate activity that can contribute to a finding of nexus. A pattern of exercising management and control from within Michigan is a strong indicator of a taxable presence.
Does Michigan Collect Sales Tax?
Yes. Michigan has a flat statewide sales tax rate of 6%. One of the unique features of Michigan’s sales tax system is that there are no local city or county sales taxes, making compliance much simpler than in states with thousands of different tax jurisdictions.
Does Michigan Tax SaaS Income?
No. Michigan’s treatment of Software as a Service (SaaS) is very favorable for tech companies. According to the Department of Treasury, SaaS is generally treated as a nontaxable service because the customer is only accessing the software remotely and does not receive a physical copy or “possession” of the software. This is a significant advantage over states like Minnesota, where SaaS is often taxable.
Does Michigan Tax Online Marketplaces?
Yes. Michigan has Marketplace Facilitator laws. Platforms like Amazon, eBay, and Walmart are required to collect and remit sales tax on behalf of third-party sellers for all sales delivered to Michigan customers.
Does Michigan Tax Remote Software Sales?
Generally, no. Prewritten computer software that is delivered strictly through electronic means is exempt from Michigan sales tax. The tax only applies if the software is transferred in a “tangible form,” such as on a disc or a USB drive.
If I Want to Close My Business in Michigan, What Will I have to Do?
To formally close a business in Michigan, you must:
- File a final tax return with the Michigan Department of Treasury and check the “Final Return” box.
- Formally dissolve or withdraw your entity with LARA.
- Cancel your sales tax registration and other tax accounts through the MTO portal.
When Is My Tax Return Due for Michigan?
Michigan corporate state taxes follow a unique schedule that gives filers extra time compared to the IRS:
-
C-Corporations: Due April 30, 2026 (for calendar year filers).
-
S-Corp/Partnership: Due April 30, 2026.
What Happens If I File My Michigan Tax Return Late?
If you file your return late, Michigan imposes a penalty of 5% of the tax due for each month or part of a month the return is late, up to 25%. Interest also accrues on any unpaid tax at a rate set annually by the Department of Treasury. These state penalties are separate from any IRS penalties for federal late filings.
