Starting an LLC in Wisconsin provides business owners with strong liability protection, flexible tax treatment, and straightforward operational requirements. Wisconsin requires three essentials under the Wisconsin Limited Liability Company Act: an approved business name, a registered agent with a Wisconsin physical address, and Articles of Organization filed with the Department of Financial Institutions. Everything else? Helpful, but not required by law.
Formation costs remain reasonable and predictable. Wisconsin charges $130 for online Articles of Organization filing (or $170 by mail), plus $25 annually for the report requirement—rates that compare favorably with neighboring states. Rejected submissions require resubmission at an additional filing fee, making initial accuracy important to avoid duplicate expenses.
Filing online saves $40 and processes faster. Choose paper, and you'll pay more for manual processing.
Wisconsin requires your LLC name to include "Limited Liability Company," "L.L.C.," or "LLC" and be distinguishable from existing entities. Search the Wisconsin Department of Financial Institutions database to verify availability before filing. Names containing restricted words like "bank," "insurance," or "cooperative" require additional approvals.
Wisconsin offers name reservations for $15, holding your chosen name for 120 days while you complete formation documents. This prevents other entities from claiming your preferred name during the formation process. Planning to operate under a different name? You'll file a "doing business as" registration with the Wisconsin Department of Financial Institutions for $15.
Wisconsin law requires that every LLC maintain a registered agent with a physical Wisconsin street address. This person or entity accepts legal documents, state correspondence, and service of process on behalf of your LLC. Post office boxes don't satisfy this requirement.
Your registered agent must be a Wisconsin resident at least 18 years old or an authorized business entity, maintain a physical Wisconsin street address (no P.O. boxes), stay available during business hours, and provide written consent to serve.
Failing to maintain proper registered agent coverage can result in administrative dissolution, loss of good standing, and missed legal documents. Many business owners choose professional registered agent services, ensuring consistent availability and maintaining privacy by keeping home addresses off public records.
Wisconsin's Articles of Organization must include specific information establishing your LLC's legal existence. Required information includes LLC name and address, registered agent information, management structure (member-managed vs. manager-managed), and organizer details.
File online through the Wisconsin Department of Financial Institutions portal for $130, or submit paper documents for $170. Online filing typically processes faster and provides immediate confirmation of receipt. The Department of Financial Institutions maintains these documents as public records, so ensure accuracy before submission.
Wisconsin doesn't legally require Operating Agreements, but they're essential for protecting your limited liability status and preventing member disputes. The 2023 Wisconsin Uniform Limited Liability Company Law allows operating agreements to be oral, written, or implied, but written agreements provide the clearest protection.
Key provisions include ownership percentages and capital contributions, management structure and voting rights, profit and loss distribution methods, member transfer restrictions, and dissolution procedures. Wisconsin's flexible LLC laws allow significant customization of these provisions matching your business needs.
Single-member LLCs benefit from operating agreements clearly separating business and personal activities, strengthening liability protection. Multi-member LLCs use operating agreements preventing disputes and establishing clear procedures for major decisions. The document doesn't get filed with the state but should be maintained with your corporate records.
Wisconsin doesn't require a general statewide business license, but specific industries need state-level licensing. Professional services may require Professional Limited Liability Company (PLLC) formation with additional licensing coordination. Contact the Wisconsin Department of Safety and Professional Services for industry-specific requirements.
Obtain a federal Employer Identification Number (EIN) from the IRS. This free number is needed for business banking, employee payroll, and certain tax filings. If selling taxable goods or services, register for Wisconsin sales tax with the Department of Revenue.
Local municipalities may require additional business permits or licenses. Check with your city or county clerk's office about zoning compliance, signage permits, or industry-specific local requirements before beginning operations.
Creating your LLC is just the beginning. Staying compliant requires consistent attention. Wisconsin demands:
Your annual report is due by the last day of the quarter in which your LLC was originally formed each year. Wisconsin charges $25 for online filings or $40 for paper filings. The report updates the state's records regarding your registered agent, principal office address, and management information. Filing can be done online through the Department of Financial Institutions portal, which provides immediate confirmation..
Can I be my own registered agent in Wisconsin?
Yes, any Wisconsin resident at least 18 years old can serve as their own registered agent. However, this makes your home address part of public record and requires availability during business hours to accept legal documents.
Do I need an attorney to form an LLC in Wisconsin?
Wisconsin law doesn't require attorney involvement for LLC formation. The process is straightforward for most businesses. However, complex ownership structures, professional licensing requirements, or significant liability concerns may justify legal consultation.
Can I change my LLC name after formation?
Yes, by filing an Amendment to Articles of Organization with the Wisconsin Department of Financial Institutions. The new name must meet Wisconsin's naming requirements and be distinguishable from other entities. Amendment fees apply, and you'll need to update all business documents, contracts, and registrations.
Can non-residents form LLCs in Wisconsin?
Absolutely. Wisconsin doesn't require LLC members, managers, or organizers to be state residents. However, you must maintain a registered agent with a physical Wisconsin address.
