How an S-Corp Election Changes Your Taxes
Nothing about your company changes. Everything about how the profit is taxed does — and so does the amount of paperwork you owe every quarter.
Quick Answer
What actually changes when an LLC elects S-corp status?
An S-corp election changes federal tax treatment only. Your Michigan LLC stays an LLC — same name, same liability protection, same annual statement due February 15. What changes is how profit is taxed. As a default LLC, the entire net profit is subject to self-employment tax at 15.3% up to the Social Security wage base and 2.9% Medicare above it. After electing S status, an owner who works in the business must take reasonable W-2 wages, and payroll taxes apply to those wages — but profit distributed beyond the wage is not subject to self-employment tax. In exchange you take on real obligations: a payroll system, quarterly 941 filings, W-2s, a separate 1120-S return with K-1s to the owners, and the risk that the IRS calls your wage unreasonably low. Michigan follows the federal classification, so the income flows to the owners' Michigan returns. Whether the savings beat the added cost depends on your numbers — that is a CPA conversation, and Clear Path does not give tax advice.

How to approach it
Confirm you are eligible
The entity must be domestic, have 100 or fewer owners, have only one class of ownership interest, and have only eligible owners — individuals, certain trusts and estates. A partnership, a corporation, or a nonresident alien owner disqualifies the election.
Run the numbers with a CPA
Compare the self-employment tax saved against payroll service cost, the 1120-S return, and the higher chance of scrutiny. Below a certain profit level the election costs more than it saves, and the break-even point depends on your industry and your wage.
Set the reasonable compensation
The wage has to reflect what someone would be paid to do your job. Comparable-pay data, your hours, and your role support it. A zero or token wage with large distributions is the classic audit trigger.
File Form 2553 on time
Generally due within two months and fifteen days after the start of the tax year the election should apply to — March 15 for a calendar-year business — or any time in the preceding year. Every owner has to sign, and a married owner in a community property state may need a spousal signature.
If you are late, use the relief procedure
Revenue Procedure 2013-30 allows a late election generally within three years and 75 days of the intended effective date, with a reasonable cause statement written on the form. This works often and people do not know it exists.
Set up payroll before the first paycheck
Register for federal and Michigan withholding, run wages on a real schedule, file the quarterly 941s and the annual W-2 and W-3. The election is only as good as the payroll behind it.
Default LLC vs S-corp election

| Payroll filings | None required for owners | 941s, W-2, W-3, state withholding |
| Michigan annual statement | Due February 15 | Due February 15 (unchanged) |
| Typical yearly added cost | — | Payroll service plus a separate business return |
