How to Form S-Corp in Michigan

Quick Answer

To form an S-Corp in Michigan, you must first incorporate as a regular corporation with the Michigan Department of Licensing and Regulatory Affairs (LARA), then elect S-Corp tax status with the IRS using Form 2553. As of April 2026, contact the Secretary of State for current filing fees and processing times. Michigan has a flat 4.25% income tax rate and no franchise tax for corporations.

Step-by-Step Formation Process

1. Choose and Reserve Your Corporate Name

   • Search name availability on the Michigan LARA website
   • Ensure the name includes “Corporation,” “Incorporated,” “Company,” or approved abbreviations
   • File Form CSCL/CD-540 to reserve the name for 6 months if needed

2. Appoint a Registered Agent

   • Designate a Michigan resident or authorized business entity
   • The agent must have a Michigan street address (not a P.O. Box)
   • This can be yourself, a professional service, or another qualified individual

3. File Articles of Incorporation

   • Complete Form CSCL/CD-502 (Articles of Incorporation)
   • Submit to Michigan Department of Licensing and Regulatory Affairs
   • Include required information: corporate name, registered agent, authorized shares, incorporator details
   • File online through the LARA website or mail to the Corporations Division

4. Obtain Federal Employer Identification Number (EIN)

   • Apply directly with the IRS online, by phone, fax, or mail
   • Use IRS Form SS-4 or apply online at IRS.gov
   • This is required for tax filings and opening business bank accounts

5. File Form 2553 for S-Corp Election

   • Submit IRS Form 2553 within 75 days of incorporation
   • All shareholders must sign the form
   • This elects federal S-Corporation tax treatment

6. Create Corporate Bylaws

   • Draft internal governance documents
   • Define shareholder rights, director responsibilities, and meeting procedures
   • Not filed with the state but required for corporate compliance

7. Hold Initial Board of Directors Meeting

   • Adopt bylaws, elect officers, and authorize share issuance
   • Document decisions in corporate minutes
   • Issue stock certificates to initial shareholders

Tax Implications

Federal Tax Treatment: S-Corporations are pass-through entities for federal tax purposes. Profits and losses flow through to shareholders’ personal tax returns, avoiding double taxation. Shareholders who work in the business must receive reasonable compensation subject to payroll taxes.

Michigan State Taxes: As of April 2026, Michigan imposes a 4.25% flat income tax rate. S-Corporation income passes through to shareholders and is taxed at the individual level. Michigan does not impose a franchise tax on corporations, which can result in significant savings compared to other states.

Employment Taxes: Shareholder-employees must pay Social Security and Medicare taxes on wages. S-Corp distributions above reasonable salary are not subject to self-employment taxes, providing potential tax savings over sole proprietorships or partnerships.

Ongoing Obligations

Annual Report: Michigan corporations must file an annual report with LARA. Contact the department for current deadlines and fees, as these change periodically.

Federal Tax Filings:

• File Form 1120S (S Corporation Income Tax Return) annually by March 15th
• Issue Schedule K-1 to each shareholder showing their share of income, deductions, and credits
• Maintain payroll tax compliance for shareholder-employees

State Tax Filings: S-Corporation income flows through to shareholders’ Michigan individual tax returns (Form MI-1040). The corporation may need to file informational returns depending on specific circumstances.

Corporate Maintenance:

• Hold annual shareholder and board meetings
• Maintain corporate minutes and records
• Update registered agent information when necessary
• Comply with any licensing requirements for your specific business type

Registered Agent

Michigan law requires all corporations to maintain a registered agent with a street address in Michigan. The registered agent receives official state correspondence, legal documents, and service of process on behalf of the corporation.

Registered Agent Requirements:

• Must be a Michigan resident or authorized business entity
• Must maintain a Michigan street address (P.O. Boxes not acceptable)
• Must be available during normal business hours
• Must promptly forward documents to the corporation

Options for Registered Agent Service:

1. Self-Service: You can serve as your own registered agent if you meet the requirements
2. Professional Service: Hire a registered agent company for privacy and reliability
3. Attorney or Accountant: Many professional service providers offer registered agent services

Common Mistakes to Avoid

1. Missing the S-Corp Election Deadline File Form 2553 within 75 days of incorporation or risk waiting until the following tax year for S-Corp status.

2. Inadequate Shareholder Compensation Shareholder-employees must receive reasonable wages. The IRS scrutinizes S-Corps that pay minimal salaries to avoid payroll taxes.

3. Mixing Personal and Business Finances Maintain separate bank accounts and detailed financial records to preserve corporate liability protection.

4. Ignoring Annual Report Requirements Failure to file annual reports can result in administrative dissolution and loss of good standing status.

5. Exceeding Shareholder Limits S-Corporations cannot have more than 100 shareholders, and all must be U.S. citizens or residents.

6. Improper Stock Structure S-Corps can only have one class of stock, though voting and non-voting shares are permitted.

7. Neglecting Corporate Formalities Hold required meetings, maintain minutes, and follow bylaws to avoid piercing the corporate veil.

Frequently Asked Questions

How long does it take to form an S-Corp in Michigan?

Contact the Michigan Department of Licensing and Regulatory Affairs for current processing times, as these vary based on filing method and seasonal volume. Expedited processing may be available for an additional fee. The S-Corp tax election with the IRS typically processes within 60 days of filing Form 2553.

Can I be my own registered agent in Michigan?

Yes, you can serve as your own registered agent if you are a Michigan resident with a street address in the state. However, many business owners prefer professional registered agent services for privacy and to ensure someone is always available to receive important documents during business hours.

What’s the difference between an LLC and S-Corp in Michigan?

Both offer liability protection and pass-through taxation, but S-Corps have more restrictions (100 shareholder limit, one class of stock, citizenship requirements) while potentially offering payroll tax savings. LLCs provide more operational flexibility but don’t offer the same potential employment tax advantages for working owners.

Do I need an attorney to form an S-Corp in Michigan?

While not legally required, consulting with an attorney or accountant is advisable given the complexity of corporate formation and S-Corp tax elections. Professional guidance helps ensure compliance with all requirements and proper structuring for your specific situation.

Can I convert my existing Michigan LLC to an S-Corp?

You cannot directly convert an LLC to a corporation. You would need to form a new corporation and potentially transfer LLC assets to the corporation, which may have tax implications. Alternatively, an LLC can elect S-Corp tax treatment using Form 8832 and Form 2553 without changing its legal entity structure.

What happens if I miss the S-Corp election deadline?

If you miss the 75-day deadline to file Form 2553, your corporation will be taxed as a C-Corporation for the current tax year. You can file for S-Corp status for the following tax year or request late election relief from the IRS under specific circumstances.

Are there restrictions on S-Corp shareholders in Michigan?

Yes, S-Corporations are limited to 100 shareholders, all of whom must be U.S. citizens or residents. Shareholders cannot be corporations, partnerships, or most trusts. Only one class of stock is permitted, though voting and non-voting shares are allowed.

How much should I pay myself as an S-Corp owner-employee?

The IRS requires shareholder-employees to receive “reasonable compensation” comparable to what you would pay someone else for the same work. This prevents abuse of the employment tax savings benefit. Consult with a tax professional to determine appropriate salary levels for your situation.
