A Michigan LLC pays the state's flat 4.25% personal income tax on pass-through profit. Federally, a single-member LLC is a disregarded entity and a multi-member LLC is a partnership by default. An S-corp election cuts self-employment tax once net income passes $40,000-$60,000. Non-resident owners with no US effectively connected income owe no US federal income tax but file Form 5472 each year.
A Michigan LLC pays a flat 4.25% state personal income tax on profit that passes through to the owner, plus federal tax under the LLC's default or elected classification. Michigan charges no separate entity-level income tax on a standard LLC. By default, a single-member LLC is a disregarded entity taxed on Schedule C, and a multi-member LLC is a partnership filing Form 1065. An LLC elects S-corporation or C-corporation treatment when that lowers total tax. The 4.25% Michigan rate applies to pass-through profit regardless of the federal election.
Michigan applies a flat 4.25% personal income tax to LLC profit that passes through to the owner's individual return. The rate is the same across income levels, unlike a graduated bracket system. Michigan levies no franchise tax on LLC income in the Delaware sense. A resident owner reports the pass-through profit on the Michigan individual return; a non-resident owner reports only Michigan-source income. Some Michigan cities add a local income tax on top of the state rate. Detroit, Grand Rapids, Lansing, and several other Michigan cities impose a local income tax, so a business located in one of those cities checks the municipal rate in addition to the 4.25% state rate. An LLC with no physical Michigan presence and no Michigan-source income owes neither the state nor the local tax.
A single-member Michigan LLC is a disregarded entity, taxed on Schedule C of the owner's personal 1040. A multi-member LLC is a partnership, filing Form 1065 and issuing K-1s to members. Neither pays federal entity-level tax by default. The pass-through structure means profit is taxed once, at the owner level, rather than at both the entity and owner level. An LLC changes this only by electing corporate treatment on Form 8832 or S-corporation treatment on Form 2553. A C-corporation election, by contrast, taxes profit at the corporate level and again when distributed as a dividend, which suits few small LLCs. Most Michigan LLCs stay on the pass-through default or elect S-corp status once income is high enough to justify the payroll compliance.
An LLC elects S-corporation treatment on IRS Form 2553 to split income into a reasonable salary and distributions, where the distribution portion avoids the 15.3% self-employment tax. The election becomes worthwhile once net income passes $40,000-$60,000 per year. Below that range, the payroll compliance cost of running an S-corp outweighs the self-employment tax savings. Michigan's flat 4.25% income tax applies whether or not the LLC elects S-corp status, so the election is a federal self-employment tax decision rather than a state one.
Default Michigan LLC owners pay 15.3% self-employment tax on net business income: 12.4% Social Security up to the $168,600 wage base plus 2.9% Medicare. An S-corp election reduces this on the distribution portion. The self-employment tax funds Social Security and Medicare, and it applies on top of federal and Michigan income tax. An S-corp election trades a portion of that 15.3% for payroll compliance cost, which is why the crossover point sits near $40,000-$60,000 in net income.
A non-resident owner of a Michigan LLC owes US federal income tax only on US effectively connected income. An LLC with no US ECI owes a Form 5472 information filing but no US income tax on foreign-earned profit. Michigan taxes only Michigan-source income for a non-resident owner. A non-resident with US ECI files a US return and pays US income tax on that income, and an ITIN is needed for the personal filing. Anonymousllc.co partners with US tax preparers familiar with non-resident filings.
Form 5472 is required for any US disregarded entity with 25% or more foreign ownership, filed each year alongside a pro-forma Form 1120. Most non-resident-owned single-member Michigan LLCs must file it. The form reports transactions between the LLC and its foreign owner. Missing it carries a $25,000 penalty, so a foreign-owned single-member Michigan LLC files Form 5472 with the pro-forma 1120 by the annual deadline. A multi-member LLC files Form 1065 with K-1s instead. Reportable transactions include capital contributions the owner puts into the LLC, distributions the LLC pays out, and loans between the two. A foreign owner keeps a record of every such transfer during the year, and Anonymousllc.co's tax-preparer partners assemble Form 5472 from those records at filing time.
Under the March 21, 2025 FinCEN interim final rule, domestic reporting companies are exempt from BOI reporting. Foreign reporting companies formed outside the US remain obligated. Most Michigan LLCs are domestic and currently exempt. A Michigan LLC formed by filing Articles with the Michigan Secretary of State is a domestic reporting company and falls under the exemption. A foreign-formed entity that registers to do business in Michigan files the BOI report. Anonymousllc.co files BOI reports at $150 per report when one is required.
Michigan's flat 4.25% income tax on pass-through profit is a cost that Wyoming, Nevada, and New Mexico structures reduce or avoid at the state level. Wyoming charges no state income tax at all. A founder taxed on Michigan-source income pays the 4.25% rate regardless of where the LLC is formed, because state income tax follows where the income is earned. Forming in Wyoming lowers state tax only when the income is not Michigan-source, so the comparison depends on where the business actually operates.
A Michigan LLC files a federal return each year matching its classification, a Michigan individual return reporting pass-through profit, and the $25 state annual statement due February 15. A foreign-owned single-member LLC adds Form 5472. The federal return is Schedule C for a single-member LLC, Form 1065 for a multi-member LLC, or Form 1120-S after an S-corp election. Anonymousllc.co partners with US tax preparers for the federal filings and files the Michigan annual statement as part of registered agent service. Deadlines differ by form: Form 1065 and Form 1120-S are due March 15, while Schedule C, Form 1040, and Form 5472 with the pro-forma 1120 are due in April. Marking both dates keeps a Michigan LLC clear of late-filing penalties.
A Michigan LLC files its federal return by the classification's deadline, reports pass-through profit on the owner's Michigan individual return, and pays Michigan's flat 4.25% rate on that profit. The exact federal form depends on the entity's classification. A single-member LLC reports business income on Schedule C with the owner's Form 1040, due in April. A multi-member LLC files Form 1065 by March 15 and issues K-1s to members, who then report their share on their own returns. An LLC that elected S-corp status files Form 1120-S by March 15 and runs payroll for the owner's reasonable salary. A foreign-owned single-member Michigan LLC adds Form 5472 with a pro-forma Form 1120, due in April, reporting transactions between the LLC and its foreign owner. Missing that filing carries a $25,000 penalty, so a non-resident owner tracks the federal deadline closely. Michigan's individual return follows the federal one, taxing a resident on all pass-through profit and a non-resident on Michigan-source income only. Anonymousllc.co partners with US tax preparers who handle non-resident filings and files the $25 Michigan annual statement as part of registered agent service, so the compliance calendar stays covered.
