State tax guides

Michigan LLC & corporation registration and tax requirements

A general guide to forming, registering and keeping a company compliant in Michigan. Businesses are registered with the Department of Licensing and Regulatory Affairs (LARA). Michigan has a flat state income tax, and several cities—including Detroit—add their own income tax on residents and businesses.

Single-member LLCs in Michigan

A single-member LLC is registered with the Department of Licensing and Regulatory Affairs (LARA) by filing articles of organization. For federal tax purposes it is usually a disregarded entity, and its ongoing Michigan obligations typically include: lLC annual statement due February 15; corporation annual report due May 15. Michigan taxes individual income, so owners of pass-through LLCs and S corporations generally report their share of Michigan-source profit on a Michigan return—as residents or as nonresidents.

Multi-member LLCs in Michigan

A multi-member LLC is generally taxed as a partnership and files a federal Form 1065 with K-1s for each member. In Michigan, it keeps the same registration and report obligations, and the state may require a partnership return or withholding for nonresident members. Business-level taxes to watch: Corporate income tax on C corporations; many cities also levy local income tax.

Corporations in Michigan

A corporation files articles of incorporation with the Department of Licensing and Regulatory Affairs (LARA), appoints directors and officers, and keeps its Michigan registration current. Corporate income tax on C corporations; many cities also levy local income tax. Corporations also file federal Form 1120 and, when doing business in Michigan, a Michigan corporate return where one is required.

S corporations in Michigan

An S corporation is a federal tax election (Form 2553), not a separate entity type. Not every state treats S corporations the same way—in Michigan, review how the state taxes S corporation income and whether entity-level taxes or fees still apply. Nonresident aliens cannot be S corporation shareholders, so foreign owners usually use an LLC or C corporation instead.

Foreign-owned U.S. LLCs and corporations in Michigan

Foreign individuals and companies can own an LLC or corporation in Michigan. State requirements are generally the same as for U.S. owners, but federal rules add filings such as Form 5472 with a pro forma Form 1120 for foreign-owned single-member LLCs, and possible withholding on income allocated to foreign partners. Chirino USA helps foreign owners keep both the Michigan filings and the IRS filings in order.

Companies formed in another state that do business in Michigan

An LLC or corporation formed elsewhere—such as in Delaware, Wyoming or Florida—that has employees, an office, property or regular operations in Michigan usually must register as a "foreign" entity with the Department of Licensing and Regulatory Affairs (LARA) (foreign qualification). Once registered, it generally follows Michigan's report and tax rules as well as those of its home state.

Registered agent requirements

Every LLC and corporation registered in Michigan must keep a registered agent with a physical address in the state to receive legal and state notices. Owners who live abroad or in another state typically use a commercial registered agent service.

General filing deadlines

Annual or periodic report: LLC annual statement due February 15; corporation annual report due May 15. State income or franchise tax returns generally follow federal due dates or shortly after, and extensions for state returns do not always extend the time to pay. Missing state filings can lead to penalties, loss of good standing and eventual administrative dissolution.

Multi-state business considerations

Companies that sell, hire or hold property in more than one state may have to register and file in each of them. Income is usually apportioned among states, and sales tax registration can be triggered separately from income tax. We review where your company is "doing business" so you file in Michigan and other states only where required.

This guide is general information and not legal or tax advice. State rules, fees and deadlines change; we confirm current requirements for your situation before filing.
