How to Start an LLC in Michigan: Complete 2026 Guide

How to Form an LLC: Step-by-Step

1. 1

   Choose Your Michigan LLC Name

   Select a unique name ending with 'LLC' or 'Limited Liability Company'. Search available names using Michigan's Business Entity Search on the Secretary of State website. Your name can't be identical to existing Michigan business entities.

   Choosing the right name for your Michigan LLC is more than a branding decision. It's a legal requirement that must be satisfied before you can file your formation documents. Your name must be distinguishable from every other active business entity already on file with the Michigan Department of Licensing and Regulatory Affairs, Corporations Division (or equivalent agency), meaning a name can't simply swap a common word or use a variant spelling to get around an existing registration. Before you invest in a logo or website, run a thorough name search using the Michigan LARA Corporations Online Filing System at https://cofs.lara.michigan.gov/SearchApi/Search/Search. The search is free and returns results in real time. If your first choice is taken, try variations: adding your city, a descriptor (e.g., 'Group', 'Solutions', 'Services'), or your own name. Once you confirm availability in the state database, also check the U.S. Patent and Trademark Office (USPTO) trademark database at tmsearch.uspto.gov to avoid federal trademark conflicts. State approval doesn't protect you from trademark infringement suits.

   What to Fill In

   • Entity name exactly as it should appear in Michigan records
   • Required designator: 'Limited Liability Company', 'LLC', or 'L.L.C.' (or state-approved abbreviation)
   • Name reservation applicant name and address (if filing a separate name reservation)
   • Name reservation term: typically 60 to 120 days depending on the state

   Common Rejection Reasons

   • Name isn't distinguishable from an existing business already registered in Michigan
   • Missing the required LLC designator ('LLC', 'L.L.C.', or 'Limited Liability Company')
   • Name contains a restricted or prohibited word (e.g., 'Bank', 'Insurance', 'Engineer') that requires additional state agency approval
   • Name is identical or deceptively similar to a name reserved by another applicant
   • Name implies a government affiliation (e.g., 'Federal', 'State', 'Bureau') without proper authorization

   Processing Times

   • Online: Name availability search results are instant; name reservation approval typically takes 1 to 3 business days
   • Mail: Name reservation by mail takes 1 to 2 weeks depending on state volume

   After Approval

   Once the name clears, write it down exactly as it will appear on the filing, capitalization and spacing included. Use that exact string everywhere else in the process. If you want to secure the name before you're ready to file, submit a name reservation for the applicable fee. With your name locked in, proceed immediately to selecting your registered agent so you've all the information you need for the filing form.

   Pro tip: Reserve your chosen name for 6 months by filing a Name Reservation with Michigan for $25 if you need extra time to prepare your paperwork.
2. 2

   Designate a Registered Agent

   Appoint a registered agent with a Michigan street address who can receive legal documents during business hours. This can be yourself, another person, or a professional service. The agent must maintain a physical address in Michigan.

   A registered agent (sometimes called a 'statutory agent', 'agent for service of process', or 'resident agent' depending on the state) is the person or business entity officially designated to receive legal documents on your LLC's behalf, lawsuit service of process, tax notices, and compliance warnings routed through Michigan LARA Corporations Online Filing System. The registered agent must have a physical street address in Michigan, a P.O. Box is never acceptable. You've three options: serve as your own registered agent (if you've a Michigan street address and can be there 9am to 5pm on business days), name another individual who agrees to serve in this role, or hire a professional registered agent service. Professional services typically cost $49 to $299 per year and provide guaranteed document handling, compliance reminders, and continuity if you move or travel. Michigan doesn't require members or managers to be named on the formation document, so your registered agent's address is often the only address that shows up in the public record at all, making the choice between a home address and a professional service the single biggest privacy decision in the whole process.

   What to Fill In

   • Registered agent's full legal name (individual or business entity name)
   • Registered agent's street address in Michigan (no P.O. Boxes, must be a physical location)
   • Registered agent's mailing address (if different from street address)
   • Registered agent consent or acceptance (some states require a signed consent form or a checkbox on the Articles)

   Common Rejection Reasons

   • Registered agent address is a P.O. Box, virtual office, or mail drop service
   • Address provided is outside Michigan. The agent must be a Michigan resident or entity
   • The named entity as registered agent isn't authorized to do business in the state
   • Registered agent consent is missing when required by the state
   • Registered agent's street address is incomplete (missing suite or unit number for a multi-tenant building)

   Processing Times

   • Online: The registered agent designation is part of your Articles/Certificate filing, no separate processing time
   • Mail: Same as the formation document. RA information is reviewed with the full filing

   After Approval

   Notify your registered agent immediately after your LLC is approved. They need to know they're officially listed and to be on the lookout for any documents from the state. If you used a professional service, complete their onboarding process and set up document forwarding preferences. Keep your registered agent's information current: if your RA moves, resigns, or if you switch services, you must file a statement of change with Michigan LARA Corporations Online Filing System (typically a $10 to $30 fee) before your next Annual Statement is due, failure to maintain a valid registered agent can result in your LLC being administratively dissolved.

   Pro tip: Using a professional registered agent service protects your privacy and ensures you never miss important legal notices, especially useful if you work from home.
3. 3

   File Articles of Organization

   Submit your Articles of Organization to the Michigan Department of Licensing and Regulatory Affairs with the $50 filing fee. Include your LLC name, registered agent information, and organizer details. LARA doesn't publish a standard processing time, but it sells expedited tiers starting at $50.

   Filing the Articles of Organization (CSCL/CD-700) is the official, legally binding step that creates your LLC under Michigan law. This document is submitted to the Michigan LARA Corporations Online Filing System (https://cofs.lara.michigan.gov) along with the required filing fee. Before you start the form, gather your LLC name (exactly as confirmed available), your registered agent's full name and Michigan street address, the names and addresses of all organizers (the people filing the document), and a decision on management structure (member-managed, where all members run the business, vs. manager-managed, where designated managers handle operations). Filing online is strongly recommended: you get instant confirmation of receipt, can track your filing status, and avoid mail delays. Online filers also typically receive the approved document as a downloadable PDF once it's approved. LARA doesn't publish a standard, non-expedited processing time for formation documents, so a routine filing carries no committed approval date, the only timeframes the Corporations Division commits to are the paid expedited tiers on form CSCL/CD-272 ($50 for 24-hour, $100 for same-day, $500 for two-hour, $1,000 for one-hour). Michigan calls its annual filing an 'Annual Statement' ($25 fee), due by February 15 each year. Michigan also has a Corporate Income Tax at 6% that may apply to some LLCs.

   What to Fill In

   • Name of LLC (must include 'Limited Liability Company', 'LLC', or 'L.L.C.')
   • Registered agent name and Michigan street address
   • Address of registered office
   • Name(s) of organizer(s)
   • Purpose of LLC (general purpose is acceptable)
   • Dissolution date if not perpetual
   • Organizer signature

   Common Rejection Reasons

   • LLC name conflicts with an existing Michigan business entity name or reservation
   • Registered agent address is a P.O. Box or is located outside the state
   • Filing fee payment is missing, incorrect, or made with a non-accepted payment method
   • Required fields are left blank (most commonly: management structure not selected, or organizer signature missing)
   • Incorrect or outdated form version submitted (states periodically update their official forms)
   • Name contains a restricted word (e.g., 'Bank', 'Trust', 'Insurance') without the required supplemental documentation

   Processing Times

   • Online: Not published, Michigan Department of Licensing and Regulatory Affairs, Corporations Division states no standard turnaround for online filings
   • Mail: Not published, Michigan Department of Licensing and Regulatory Affairs, Corporations Division states no standard turnaround for mailed filings, and every state that comments says mail is slower than online
   • Expedited: $50 for 24 hours for formation/qualification documents, $100 for Same day for formation/qualification documents, $500 for 2 hour, same day, and $1,000 for 1 hour, same day

   After Approval

   As soon as your Articles of Organization (CSCL/CD-700) is approved, download and save the stamped/filed copy. This is your official proof that the LLC legally exists. Store it securely in both digital and physical formats. You will need this document four times over. The IRS may ask for it when you apply for your federal EIN. A bank will ask for it to open a business account. You will need it to sign leases and contracts in the LLC's name, and to apply for certain business licenses. Some banks require a 'certified copy' of the Articles. You can typically order one from the Michigan Department of Licensing and Regulatory Affairs, Corporations Division for a small fee ($5 to $30). Your LLC's official formation date is the date stamped on the approved document.

   Pro tip: File online through Michigan's LARA website for immediate confirmation that your submission was received, and add form CSCL/CD-272 if you need a guaranteed turnaround.

   Create an Operating Agreement

   Draft an operating agreement outlining ownership percentages, management structure, and operational procedures. While Michigan doesn't require this document, it's essential for multi-member LLCs and provides legal protection for single-member LLCs.

   While Michigan doesn't legally require LLCs to file or maintain an operating agreement, courts and banks treat the absence of one as a serious red flag. An operating agreement is the internal governing document of your LLC. It sets out who owns what percentage and how profits and losses are split. It names who can make decisions and sign contracts. It says what happens when a member wants to leave or sell, and how the LLC is dissolved. Without an operating agreement, your LLC is governed by Michigan's default LLC statutes, which may not reflect your actual intentions, for example, some states default to equal profit sharing regardless of capital contributions. A single-member LLC benefits from one too. It shows the IRS, banks, and courts that the business is separate from your personal finances, and that separation is what keeps limited liability intact. Operating agreements aren't filed with the state. They're kept internally and shared with members and banks as needed. You can draft one yourself using a template, have an attorney prepare it, or use a formation service.

   What to Fill In

   • LLC name and state of formation
   • Formation date and registered agent information
   • Name, address, and ownership percentage of each member
   • Capital contributions: how much each member invested
   • Profit and loss allocation: proportional to ownership or custom split
   • Voting rights: equal votes per member or votes proportional to ownership percentage
   • Management structure: member-managed or manager-managed (with manager appointment process)
   • Buyout provisions: what happens if a member wants to exit, dies, or becomes incapacitated
   • Dissolution procedures: how and when the LLC can be wound up

   Common Rejection Reasons

   • No rejection risk. Operating agreements are private documents not reviewed by the state
   • Banks may reject your bank account application if you can't produce an operating agreement when requested
   • Courts may pierce the corporate veil (remove LLC liability protection) if no operating agreement exists and business/personal finances are commingled

   Processing Times

   • Online: Same day. You can draft and sign an operating agreement immediately after your LLC is approved
   • Mail: Not applicable. Operating agreements are internal documents

   After Approval

   Once every member has signed, and every manager if the LLC has them, give each member a copy. Keep the original in the LLC's records binder. Provide a copy to your bank when opening your business account. Most banks require it. Review and update your operating agreement any time ownership changes, new members join, or the business structure changes significantly. If the LLC has more than one member, have an attorney read the operating agreement before anyone signs. The buyout and dispute-resolution clauses are the ones worth paying to get right.

   Pro tip: Even single-member LLCs benefit from an operating agreement as it strengthens your liability protection and helps maintain your business's separate legal status.

   Obtain an EIN from the IRS

   Apply for an Employer Identification Number through the IRS website, which is free and typically processed immediately online. You'll need this federal tax ID for banking, hiring employees, and filing taxes.

   An Employer Identification Number (EIN) is a nine-digit federal tax identification number assigned by the Internal Revenue Service (IRS). Think of it as your LLC's Social Security number for tax and banking purposes. You need an EIN if the LLC has more than one member, plans to hire, files certain federal tax returns, or wants a business bank account. Even single-member LLCs that are sole proprietors for tax purposes benefit from having an EIN. Most banks require one to open a business checking account, and it lets you avoid using your personal Social Security number on vendor forms and contracts. The EIN application is free and takes about 15 minutes online at IRS.gov. You'll receive your EIN immediately upon completing the online application during IRS business hours (Monday to Friday, 7 a.m. to 10 p.m. ET). Your Michigan LLC formation document approval is a prerequisite. Apply for the EIN only after Michigan LARA Corporations Online Filing System has officially approved your LLC. Once your EIN arrives, use it to register with Michigan's tax agency for state withholding and pass-through reporting. Michigan levies a flat 4.25% individual income tax; Treasury confirmed on April 15, 2026 that the rate remains 4.25% for the 2026 tax year because the statutory rate-reduction trigger wasn't met.

   What to Fill In

   • Legal name of the LLC (exactly as approved by the state)
   • Name of the responsible party (typically the sole member or a managing member for multi-member LLCs)
   • Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) of the responsible party
   • Business address (the LLC's principal place of business)
   • Reason for applying (e.g., 'Started a new business')
   • Type of entity: Limited Liability Company
   • Number of members in the LLC
   • Date the LLC was officially formed or started business
   • Tax classification: single-member LLC (disregarded entity), multi-member LLC (partnership), or if electing S-Corp or C-Corp taxation
   • Highest number of employees expected in the next 12 months

   Common Rejection Reasons

   • Application submitted before the LLC is approved by the state (IRS may reject if no state-approved entity exists yet)
   • Responsible party's SSN or ITIN is incorrect or doesn't match IRS records
   • LLC name on the application doesn't match the name on the approved state formation document
   • Applying for a second EIN when the LLC already has one assigned (each LLC can only have one EIN)
   • Responsible party already received an EIN as an individual. You still need to apply again for the LLC entity

   Processing Times

   • Online: Immediate. EIN is issued instantly at the end of the IRS online application during business hours (Mon to Fri, 7am to 10pm ET)
   • Mail: 4 to 6 weeks via Form SS-4 submitted by mail
   • Fax: 4 business days via Form SS-4 submitted by fax (number: 855-641-6935)

   After Approval

   Print and save your IRS EIN assignment letter (Form CP 575). Banks and government agencies will ask for this document to verify your EIN. Store it with your LLC's formation documents. With your EIN in hand, you can now open a dedicated business bank account, set up business credit cards, register with Michigan LARA Corporations Online Filing System or Michigan's tax agency as applicable, and apply for professional licenses that require a tax ID number. Your EIN is also required to hire employees and to file federal tax returns for your LLC.

   Pro tip: Apply directly through the IRS website to avoid third-party services that charge unnecessary fees for this free government service.
6. 6

   Open a Business Bank Account

   Establish business banking with your Articles of Organization, EIN confirmation, and operating agreement. Keeping business and personal finances separate matters for maintaining your LLC's liability protection and simplifying tax preparation.

   Opening a dedicated business bank account is one of the most important steps for protecting your LLC's limited liability status. Whether you kept business and personal money apart is one of the key tests a court applies when deciding whether to pierce the corporate veil. Commingle the two and a court can hold you personally liable for the LLC's debts. That is the protection you formed the LLC to get. You should never use a personal account for business transactions after your LLC is formed. When choosing a bank, consider minimum balance requirements, monthly fees, transaction limits, integration with accounting software (QuickBooks, Wave, FreshBooks), and whether the bank has physical branches in Michigan. Many founders pick a national bank such as Chase, Bank of America, or Wells Fargo for the ATM network. Others prefer a local credit union, or an online-only account such as Mercury, Relay, or Novo. The online options often charge lower fees and integrate better with accounting software. Before you apply, confirm your LLC is in good standing with Michigan LARA Corporations Online Filing System. Banks routinely run a state status check, and a missed Annual Statement is one of the most common reasons an application gets delayed. Set up your bookkeeping to track state tax from day one. Michigan levies a flat 4.25% individual income tax; Treasury confirmed on April 15, 2026 that the rate remains 4.25% for the 2026 tax year because the statutory rate-reduction trigger wasn't met.

   What to Fill In

   • LLC's legal name (exactly as it appears on your formation document)
   • LLC's EIN (Employer Identification Number)
   • Approved/stamped formation document from the state (Articles or Certificate)
   • Operating agreement (most banks require this for LLCs)
   • Government-issued photo ID for each person authorized on the account
   • Initial deposit (varies by bank, can be $0 to $1,500+)
   • Business address and phone number

   Common Rejection Reasons

   • Incomplete documentation, missing EIN confirmation letter, formation document, or operating agreement
   • Bank's compliance team flags the business type as high-risk (some industries face additional scrutiny)
   • LLC not in good standing with Michigan LARA Corporations Online Filing System (e.g., missing your Annual Statement. Check your status first)
   • Inconsistencies between LLC name on documents and the name used on the application

   Processing Times

   • Online: Online bank applications can be approved in minutes to 1 to 2 business days; some banks (Mercury, Novo) offer same-day accounts
   • In person: Same-day account opening if you arrive with all required documents at a branch

   After Approval

   Once your account is open, immediately set it as the destination for all business income and the source for all business expenses. Order a business debit card and consider applying for a small business credit card to begin building your LLC's credit profile. Connect the account to your accounting software to automate transaction categorization and simplify bookkeeping. Pay yourself through owner's draws, meaning transfers from the business account to your personal one. Do not spend from the business account directly. Keep records of all draws and maintain a balance that covers your expected business expenses for at least 60 to 90 days.

   Pro tip: Shop around for business accounts as fees and features vary significantly between banks. Many credit unions offer lower fees than traditional banks for small businesses.
7. 7

   Obtain Required Business Licenses

   Research federal, state, and local licensing requirements for your specific business type. Michigan requires various licenses depending on your industry, and most municipalities require a general business license.

   LLC formation alone doesn't automatically authorize your Michigan LLC to operate. You may need one or more licenses and permits at the federal, state, county, and city levels depending on your industry and location. The most common requirement for all businesses is a general business license or business registration certificate from your city or county. Regulated industries need their own professional or occupational license on top. Healthcare, construction, real estate, food service, childcare, and financial services all qualify, and the list runs longer than that. Use the Michigan business license lookup tool at https://www.michigan.gov/lara to identify which licenses apply to your business type and location. Also check your city or county government website for local permits. Some industries need a federal license whatever the state requires. Firearms dealers, alcohol producers, motor carriers, and investment advisers are the common ones. Home-based businesses often need a home occupation permit from their city or county. If you sell taxable goods or services in Michigan, you'll register for a sales tax permit with the state revenue agency separately from anything filed through https://www.michigan.gov/lara.

   What to Fill In

   • Business type and NAICS code (used to determine applicable licenses)
   • Physical business address (determines which local permits apply)
   • EIN and LLC name (required on most license applications)
   • Professional credentials or certifications (for regulated professions)
   • Sales tax permit application (if selling taxable goods or services in your state)
   • Zoning compliance certificate or home occupation permit (for home-based businesses)

   Common Rejection Reasons

   • Business address isn't zoned for the intended business activity
   • Missing required professional certifications or proof of licensure for regulated professions
   • Delinquent taxes or outstanding fees with state or local agencies
   • Business name on the license application doesn't match the LLC's legal name with the state
   • Required inspections (health, fire, building) not completed before license application

   Processing Times

   • Online: State-level licenses: 1 to 10 business days online; some professional licenses require 30 to 90 days for background checks or examinations
   • Mail: State licenses by mail: 2 to 6 weeks; local permits may require in-person visits
   • Professional licenses: Professional licenses (contractor, CPA, attorney, doctor) can take 30 to 180 days depending on examination and background check requirements

   After Approval

   Post each required license or permit prominently at your place of business as required by law. Set renewal reminders in your calendar for all licenses. Many expire annually and late renewal brings fines or forced closure. Register for Michigan state sales tax with the state revenue agency if you sell taxable products or services. This is a separate requirement from your LLC formation. If you hire employees, register for Michigan employer withholding and unemployment insurance within the timeframe required by state law (typically within 20 to 30 days of your first hire). Review your license requirements alongside your Annual Statement each year, as your business grows into new product lines or new locations, additional permits may be required.

   Pro tip: Check with your city clerk's office for local business license requirements, as these vary by municipality and are separate from state licensing requirements.
