Michigan is one of the cheaper states to form a business in, with a $50 filing fee and a sales tax that never gets more complicated than the flat state rate, no city or county add-ons to track. Here's what it takes to start a business in Michigan in 2026.

1. Which business structure fits you?

Before you file anything, it helps to know what you're actually choosing between.

  • Sole proprietorship. No filing required to start, and you and the business are legally the same entity. Simple, but you're personally liable for whatever the business owes.
  • Partnership. Two or more people running a business together, with the same liability exposure as a sole proprietorship, just split across partners.
  • LLC. The most common structure for small businesses in Michigan. It separates your personal assets from the business's debts and lawsuits.
  • Corporation, either S-corp or C-corp. More paperwork and more formality, usually worth it once you're bringing on investors or multiple shareholders.

LLCs and corporations register with the Michigan Department of Licensing and Regulatory Affairs (LARA), Corporations Division, the agency that handles business filings statewide. Sole proprietorships and general partnerships don't register there.

2. Register your business

Forming an LLC

You form an LLC in Michigan by filing Articles of Organization with LARA. The filing fee is $50, one of the lowest in the country, and standard processing takes about 3 to 5 business days.

Every LLC needs a resident agent, Michigan's term for a registered agent, with a physical in-state address. You can act as your own agent, or hire a commercial service.

Michigan doesn't require an operating agreement by law, but it's still worth writing one, particularly for multi-member LLCs, to spell out how decisions and profits get split.

Sole proprietorships and DBAs

Sole proprietorships don't file with LARA. If you're operating under an assumed name, you'll register it as a Certificate of Assumed Name with the county clerk in the county where your business is located.

3. Get an EIN

An Employer Identification Number is free straight from the IRS and takes about 15 minutes online. You'll need one to open a business bank account, hire anyone, or file most business tax forms, even if you're a single-member LLC with no employees.

4. Check licenses and permits

Michigan doesn't issue a single general business license either. What you need depends on your industry and city: professional licensing for regulated fields, a sales tax license from the Department of Treasury if you sell taxable goods, and any local permits your city requires. Our guides on professional licensing by industry and zoning laws for home businesses cover more of this.

5. Understand Michigan taxes

Michigan has a flat personal income tax rate of 4.25%. A handful of cities, including Detroit, Grand Rapids, and Lansing, add their own local income tax on top, so where you live and work matters even though the state rate doesn't change. If your LLC elects corporate tax treatment, the Michigan Corporate Income Tax is 6%, though businesses with gross receipts under $350,000 are exempt.

Sales tax is a flat 6% statewide, and unlike most states, Michigan doesn't allow cities or counties to add anything on top, so the rate is the same everywhere in the state.

6. Stay compliant

Every Michigan LLC files an Annual Statement with LARA by February 15 each year, starting the year after formation. The fee is $25. There's no monetary late penalty for missing it, but falling behind for two or more consecutive years can lead to involuntary dissolution, so it's still worth filing on time.
