## How to form an LLC in Michigan
A **Limited Liability Company (LLC)** is a business structure that combines the limited-liability protection of a corporation with the tax flexibility and operational simplicity of a partnership or sole proprietorship. Forming one in Michigan is straightforward — but maintaining one correctly is where most owners stumble.
### Michigan LLC formation cost
- **Initial filing (Articles of Organization):** $50
- **Annual obligations:** $25 annual statement.
## The 6-step formation process
**1. Choose a unique name.** Your LLC name must be distinguishable from other business entities registered in Michigan and must include "LLC", "L.L.C.", or "Limited Liability Company". Reserve the name (about $25-$50 in most states) if you're not ready to file yet.
**2. Designate a registered agent.** Every LLC must have a registered agent — a person or company with a physical address in the state who can receive legal process and official correspondence. You can be your own registered agent (if you live in the state) or hire a service ($100-$300/year).
**3. File the Articles of Organization** (sometimes called Certificate of Formation or Certificate of Organization) with the Secretary of State. This is the formation document. Pay the filing fee.
**4. Create an Operating Agreement.** Most states don't require this to be filed, but every LLC should have one — it governs how the LLC is run (ownership percentages, voting rights, profit distributions, what happens when a member dies or leaves). Without one, the state's default LLC statute fills the gaps — usually badly.
**5. Obtain an EIN** (Employer Identification Number) from the IRS. Free at irs.gov. Required to open a business bank account, hire employees, and file taxes.
**6. Open a business bank account** in the LLC's name. Critical for maintaining liability protection — comingling personal and business funds can pierce the LLC veil.
## How LLCs are taxed
**Default ("pass-through") taxation** — single-member LLCs are taxed as sole proprietorships; multi-member LLCs are taxed as partnerships. The LLC files an informational return (or Schedule C); profits and losses flow through to the members' personal tax returns.
**S-corp election** — once profits exceed about $50,000-$80,000/year, many small businesses benefit from electing S-corp tax treatment (Form 2553). This can save self-employment tax on the portion of profits taken as distributions rather than salary. Talk to a CPA before electing.
**C-corp election** — rare for LLCs, but possible (Form 8832). Generally only makes sense for businesses raising venture capital or planning to retain significant earnings.
## What an LLC protects you from
**LLCs DO protect you from:**
- Most contract debts of the business
- Tort claims arising from the business's operations (without your personal involvement)
- Lawsuits against the business that don't involve you personally
**LLCs DO NOT protect you from:**
- Personal guarantees you sign
- Your own torts (negligence, fraud, professional malpractice)
- Unpaid payroll taxes (IRS comes after responsible individuals)
- Co-mingling of personal and business funds (can pierce the veil)
- Personal injury you cause directly (driving a company vehicle, etc.)
## Ongoing maintenance
To keep your LLC's protection intact:
- **File the annual report** (or pay the franchise tax) on time
- **Renew the registered agent** as needed
- **Keep business and personal finances completely separate** — separate bank accounts, no personal expenses on business cards
- **Sign contracts in the LLC's name** — "John Smith, Manager of XYZ LLC" not just "John Smith"
- **Hold member meetings and document decisions** — even single-member LLCs benefit from written resolutions for major decisions
- **Maintain insurance** — LLC protection is real but not absolute; general liability and professional liability insurance fill gaps
## Series LLCs
Some states (DE, IL, NV, OK, TX, TN, UT, others) recognize **Series LLCs** — a master LLC under which multiple "series" can be created, each with separate assets, liabilities, and members. Useful for real-estate investors and businesses with multiple distinct lines of activity. Tax treatment of series LLCs is still evolving at the IRS.
## Anonymous / privacy LLCs
**Wyoming, New Mexico, Delaware, and Nevada** allow LLCs whose members aren't publicly disclosed in state filings. Useful for privacy and (modest) asset protection — but doesn't shield from court orders, creditors who do their homework, or federal tax obligations.
## Single-member LLC trap
Single-member LLCs are popular but have a unique vulnerability: in some states (and especially in bankruptcy), creditors of the single member can reach the LLC's assets through a charging order — and a few jurisdictions have allowed full foreclosure of the membership interest. Multi-member LLCs (even with a 99/1 split) typically have stronger asset protection.
## What you should do
Forming an LLC yourself is realistic for simple single-owner businesses — most Michigan Secretary of State websites have step-by-step guides. Hire a business attorney when you have multiple founders (you NEED a custom Operating Agreement), are raising outside money, are taking on real-estate or other significant assets, or have any partnership-disagreement risk. Many Michigan attorneys offer flat-fee LLC formation packages that include a custom operating agreement.
