How to Form an LLC in Wisconsin

Here are the steps you need to take to form an LLC in Wisconsin. For more information on how to form an LLC in any state, see Nolo's article How to Form an LLC.

1. Choose a name for your LLC.
2. Appoint a registered agent.
3. File Articles of Organization.
4. Prepare an operating agreement.
5. Comply with tax and regulatory requirements.
6. File annual reports.

1. Choose a Name for Your LLC

Under Wisconsin law, an LLC name must contain the words "Limited Liability Company" or "Limited Liability Co.," or end with the abbreviation "LLC" or "L.L.C."

Your LLC’s name must be distinguishable from the names of other business entities already on file with the Wisconsin Department of Financial Institutions. Names may be checked for availability at the Wisconsin Department of Financial Institutions business name database.

You may reserve a name for 120 days by filing a Name Reservation Application (Form 1) with the Wisconsin Department of Financial Institutions. The reservation must be filed by postal mail.

2. Appoint a Registered Agent

Every Wisconsin LLC and Foreign LLC doing business in Wisconsin must have an agent for service of process in the state. This is an individual or business entity that agrees to accept legal papers on the LLC’s behalf if it is sued. The registered agent may be a Wisconsin resident or a business entity authorized to do business in Wisconsin. The registered agent must have a physical street address in Wisconsin.

3. File Articles of Organization

A Wisconsin LLC is created by filing Articles of Organization (Form 502) with the Wisconsin Department of Financial Institutions. The articles must include:

• the LLC's name
• the name and address of the LLC’s registered agent
• whether the LLC will be member-managed or manager-managed
• the name and address of each organizer
• the LLC's email address and phone number,
• the signature of the LLC's organizer, and
• the name of the drafter of the articles.

The articles may be filed online at the Wisconsin Department of Financial Institutions website or by postal mail. The filing fee is $170 for filing by mail and $130 for filing online.

4. Prepare an Operating Agreement

An LLC operating agreement is not required in Wisconsin, but is highly advisable. The Operating Agreement is the primary document that establishes the rights, powers, duties, liabilities, and obligations of the members among themselves and to the LLC. The Operating Agreement is purely an internal document and is not filed with the Secretary of State. If an existing or newly created LLC does not adopt an operating agreement, its existing articles of organization, bylaws, or operating agreement, and/or its member control or limited liability company agreement will collectively become its operating agreement.

All of the paperwork and procedural steps to start a limited liability company can be done online using Nolo's Online LLC Formation service.

5. Comply With Tax and Regulatory Requirements

Additional tax and regulatory requirements may apply to your LLC. These may include:

EIN: If your LLC has more than one member, it must obtain its own IRS Employer Identification Number (EIN), even if it has no employees. If you form a one-member LLC, you must obtain an EIN for it only if it will have employees or you elect to have it taxed as a corporation instead of a sole proprietorship (disregarded entity). You may obtain an EIN by completing an online EIN application on the IRS website. There is no filing fee.

Business Licenses: Depending on its type of business and where it is located, your LLC may need to obtain other local and state business licenses. For local licenses, check with the clerk for the city where the LLC's primary place of business is located (or county if it is in an unincorporated area). For state license information, consult the Wisconsin Department of Safety and Professional Services website. For more information, see Nolo's article How to Get a Small Business License in Wisconsin.

Department of Revenue: In some cases, for example if you have employees or will be selling goods and collecting sales tax, you’ll need to register with the Wisconsin Department of Revenue (DOR). You can register online (using the DOR’s Taxpayer Access Point (TAP)) or on paper (using Form BTR-101, Application for Business Tax Registration). For more information on state LLC tax registration, check Nolo's article, Wisconsin LLC Annual Filing Requirements.

6. Annual Report

Every domestic and foreign LLC transacting business in Wisconsin must file an annual report with the Department of Financial Institutions. The report must be filed online at the Department of Financial Institutions website. The annual report is due at the end of the calendar quarter of the anniversary month of the LLC's formation. For example, an LLC formed on July 15 must file the report by September 30. The due dates are March 31st, June 30th, September 30th, and December 31st. The Department will send a notice to your LLC's registered agent with instructions on how to complete the online filing. The filing fee is $25 for a domestic LLC and $80 for a foreign LLC.

Wisconsin LLC FAQ

Should I form an LLC?

If you are just starting your business or have already been operating as a sole proprietor, you should consider forming an LLC. LLCs limit an owner's personal liability for business debts and lawsuits and offer a lot of flexibility when it comes to ownership, management, and taxation of the business. To learn more about LLCs and decide if it is the right business structure for you, see What is a Limited Liability Company (LLC)?

How do I know if my LLC name is available?

It is important to make sure that your LLC's name is distinguishable from the names of other existing businesses on file with the Wisconsin Department of Financial Institutions. You can conduct a name search for free on the Wisconsin DFI website to make sure your proposed name is available.

How much does it cost to form an LLC in Wisconsin?

• The Wisconsin Department of Financial Institutions charges a $170 fee to file the Articles of Organization by mail and $130 to file online.
• It will cost $15 to file a name reservation application, if you wish to reserve your LLC name prior to filing the Articles of Organization.

Filing on your own is often the cheapest option, but completing all of the forms and filing them yourself can be complicated.

Do I need an operating agreement for my Wisconsin LLC?

Wisconsin does not require LLCs to have operating agreements, but it is highly advisable to have one. An operating agreement will help protect your limited liability status, prevent financial and managerial misunderstandings, and ensure that you decide on the rules governing your business instead of state law by default. For more information, see The LLC Operating Agreement.

Can a foreign LLC do business in Wisconsin?

To do business in Wisconsin, all LLCs organized outside of the state must register with the Wisconsin Department of Financial Institutions. Foreign LLCs must appoint a registered agent for service of process. The agent may be a Wisconsin resident or a business entity authorized to do business in Wisconsin.

To register, file a Foreign Limited Liability Company Certificate of Registration Application (Form 521) with the Wisconsin Department of Financial Institutions. The application must be filed online. The filing fee is $100.

Before filing, make sure the LLC’s name is available in Wisconsin by checking the state's business name database. If the name is not available in Wisconsin, you should obtain a fictitious business name for use in the state and register with that name. To do so, file a Name Registration Application-Foreign Corporation or Foreign Limited Liability Company (Annual) (Form 1-R) with the Department of Financial Institutions. The filing fee is $50. The form must be filed by mail.

A Foreign LLC must file a new name registration application every year. All foreign LLC name registrations expire on December 31 of each year. A renewal application must be filed between October 1 and December 31. The application procedure and filing fee for a renewal is the same as for an original application, except that it is indicated as a renewal.

Can I form a single-member LLC in Wisconsin?

For most formation purposes, a Wisconsin single-member LLC is considered the same as a multi-member LLC. The steps to form a single-member LLC in Wisconsin are the same as those listed above.

Single-member LLCs do have additional flexibility when it comes to filing a tax return. To learn more, see Nolo’s article, How Single-Member LLCs Pay Federal Income Tax.

Can I form a professional LLC in Wisconsin?

Generally, if you provide a service that requires you to obtain a Wisconsin state license before practicing, then you are a professional service. Each member of the company must be licensed in order to form a PLLC. To learn more about forming a Wisconsin PLLC, see our article, How to Form a Professional LLC in Wisconsin.
