S-Corp Election in Michigan (Form 2553)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 20, 2026 · Last updated Aug 20, 2026

A Michigan business elects S-corporation status by filing IRS Form 2553 — there is no separate Michigan election and no IRS filing fee. File no more than 2 months and 15 days after the start of the tax year the election takes effect, or any time in the preceding year. Michigan then treats the entity as a flow-through and taxes owners at 4.25%.

Quick Answer

Form: IRS Form 2553, Election by a Small Business Corporation
IRS fee: $0 - the IRS charges nothing to file Form 2553
Deadline: 2 months and 15 days after the tax year begins, or any time in the prior year
Michigan election: None - Michigan follows the federal S classification
Michigan individual rate: 4.25% for the 2026 tax year
Michigan CIT: 6%, generally applies to C corporations rather than S corporations
Flow-through entity tax: Elective 4.25% entity-level tax with a refundable member credit
Required after election: W-2 payroll for owner-employees and Form 1120-S each year

What the S-Corp Election Is

An S corporation is not a type of company you form at the Michigan Department of Licensing and Regulatory Affairs. It is a federal tax classification elected under 26 U.S.C. § 1362. You first create a legal entity — almost always a Michigan LLC or a Michigan corporation — and then ask the IRS to tax that entity under Subchapter S by filing Form 2553, Election by a Small Business Corporation.

The point of the election is payroll tax. In a default LLC, all of the owner's share of net profit is subject to self-employment tax at 15.3%. In an S corporation, the owner-employee receives reasonable compensation as W-2 wages subject to FICA, and any remaining profit is distributed without self-employment tax. The federal income tax on the profit is unchanged; only the payroll-tax layer moves.

Nothing about the election changes your liability shield, your Michigan registered agent obligation, or your Michigan annual filings. See S-corp vs LLC for the structural comparison and Form 2553 explained for a line-by-line walkthrough.

Eligibility Requirements

Section 1361 limits which entities may be S corporations. The entity must:

be a domestic corporation or an eligible entity electing corporate treatment;
have only allowable shareholders — individuals, certain trusts, and estates; no partnerships, corporations, or non-resident alien shareholders;
have no more than 100 shareholders;
have only one class of stock; and
not be an ineligible corporation such as certain insurance companies, domestic international sales corporations, or financial institutions using the reserve method for bad debts.

An LLC electing S status must also make sure its operating agreement does not create what looks like a second class of stock. Disproportionate distributions or preferred returns written into a Michigan operating agreement can jeopardize the election, so amend the agreement to require pro-rata distributions before filing.

The Filing Deadline

Timing is the part people get wrong. Under the Form 2553 instructions, a completed election must be filed either:

no more than 2 months and 15 days after the beginning of the tax year the election is to take effect — for a calendar-year business, that is roughly March 15; or
at any time during the tax year preceding the tax year it is to take effect.

A newly formed Michigan entity counts its 2-month-and-15-day window from the earliest of the date it first had shareholders, first had assets, or first began doing business — not from the date LARA stamped the filing.

Miss the window and the IRS provides late election relief for entities that intended to be S corporations, had reasonable cause, and are otherwise eligible. You claim it by writing the reasonable-cause explanation on Form 2553 itself. Relief is common but not automatic, so file on time when you can.

How to File Form 2553 in Michigan

Form the entity. File Michigan articles of organization with LARA for an LLC, or articles of incorporation for a corporation. Confirm the name on the Michigan business entity search.
Get an EIN. Form 2553 requires the entity's federal EIN. It is free and issued immediately online.
Complete Form 2553. Enter the legal name and EIN exactly as they appear on the entity's records, the effective date, the tax year, and shareholder information.
Collect every shareholder's consent. All shareholders on the effective date must sign. A missing signature invalidates the election.
File it with the IRS by fax or mail to the service center listed for Michigan in the Form 2553 instructions. There is no IRS filing fee.
Watch for the CP261 notice confirming acceptance, generally within about 60 days. If it does not arrive, follow up rather than assuming approval.

Does Michigan Require a Separate State S-Corp Election?

No. Michigan does not have a separate state-level S-corporation election form. Michigan follows the federal classification: once the IRS accepts Form 2553, the entity is treated as a flow-through entity for Michigan purposes and its income passes to the owners, who report it on the Michigan individual income tax return. There is no Michigan analogue to Form 2553 to file with the Department of Treasury.

Two Michigan consequences follow. First, Michigan's Corporate Income Tax — a 6% tax on C corporations — generally does not apply to an entity taxed federally as an S corporation, because Michigan's CIT reaches corporations taxed as C corporations. Second, the income instead lands on the owners and is taxed at Michigan's individual income tax rate, which the Department of Treasury announced as 4.25% for the 2026 tax year under MCL 206.51.

Michigan's Flow-Through Entity Tax

Michigan offers an elective flow-through entity (FTE) tax administered by the Department of Treasury. A flow-through entity — including an S corporation or a partnership — can elect to pay Michigan tax at the entity level at the same 4.25% rate, and its members then claim a refundable credit on their Michigan returns for their share of the tax paid. The election is made through Michigan Treasury Online, and the entity files Form 5772 with Form 5774 reporting each member's share.

The reason owners consider it is federal: an entity-level state tax is deductible by the entity, which can work around the federal cap on individual state and local tax deductions. It is a genuine planning tool for a profitable Michigan S corporation, but it is an election with its own timing rules and it does not change the entity's federal S status. Confirm the current election window and forms with Treasury before relying on it. See Michigan LLC tax filing requirements for the wider picture.

Reasonable Compensation and Payroll

The election only works if the owner-employee takes reasonable compensation before distributions. The IRS position is that S corporation officers who perform services are employees and their pay is wages subject to employment taxes; recharacterizing wages as distributions is one of the most frequently litigated S-corp issues. There is no safe-harbor percentage. Support the number with what a comparable role pays in your industry and region for the hours actually worked.

Payroll is the real cost of the election. You must register for Michigan withholding with Treasury, run actual payroll, file federal Forms 941 and 940 and W-2s, and file Michigan withholding returns. Add corporate bookkeeping and a Form 1120-S each year. Those recurring costs are why the election usually pays off only once profit meaningfully exceeds a defensible salary.

When It Makes Sense — and When It Does Not

Factor	Default Michigan LLC	Michigan LLC with S election
Federal return	Schedule C or Form 1065	Form 1120-S plus K-1s
Self-employment tax	15.3% on all net profit	FICA on wages only
Payroll required	No	Yes - owner must take W-2 wages
Michigan election needed	n/a	None - Michigan follows the federal election
Michigan CIT (6%)	Not applicable	Generally not applicable
Michigan FTE tax	Elective	Elective at 4.25% with refundable member credit
Ongoing cost	Low	Payroll plus corporate accounting

Skip the election if profit is modest, if you reinvest nearly everything, if you have foreign or entity owners, or if you want the flexible special allocations a partnership allows. Revisit it annually — the answer changes as profit grows.

Frequently Asked Questions

Does Michigan require a separate S-corp election?

No. Michigan has no state-level S-corporation election form. Once the IRS accepts Form 2553, Michigan treats the entity as a flow-through entity and the income passes to the owners, who report it on the Michigan individual income tax return. There is nothing analogous to Form 2553 to file with the Department of Treasury.

When is the deadline to file Form 2553 in Michigan?

File no more than 2 months and 15 days after the beginning of the tax year the election is to take effect, which is roughly March 15 for a calendar-year business, or at any time during the preceding tax year. A new entity counts from the earliest of when it first had shareholders, assets, or began doing business.

How much does the S-corp election cost?

The IRS charges no fee to file Form 2553. The real cost is ongoing: running W-2 payroll for owner-employees, filing federal Forms 941, 940, and W-2s, registering Michigan withholding with the Department of Treasury, and filing Form 1120-S plus shareholder K-1s each year.

What is Michigan's flow-through entity tax?

It is an elective entity-level tax administered by the Michigan Department of Treasury. A flow-through entity can elect to pay Michigan tax at 4.25% at the entity level, and its members claim a refundable credit on their Michigan returns for their share. The election is made through Michigan Treasury Online using Forms 5772 and 5774.

Can a Michigan LLC elect S-corp status?

Yes. An LLC that meets the Subchapter S eligibility rules can elect corporate treatment and S status on Form 2553. Check the operating agreement first: disproportionate distributions or preferred returns can look like a second class of stock, which disqualifies the election, so amend to require pro-rata distributions.

What happens if I miss the Form 2553 deadline?

The IRS provides late election relief for entities that intended to be S corporations from the requested effective date, had reasonable cause for the delay, and are otherwise eligible. You claim it by writing a reasonable-cause explanation directly on Form 2553. Relief is frequently granted but is not automatic.

Does an S-corp election eliminate self-employment tax?

It does not eliminate payroll tax; it changes the base. The owner-employee must take reasonable compensation as W-2 wages subject to FICA, and only the remaining profit is distributed free of self-employment tax. The IRS treats officers who perform services as employees and challenges artificially low salaries.
