How to Start an LLC in Wisconsin

Written by Melissa Pedigo – CPA, updated on

Wisconsin has a history of innovation and entrepreneurship. From Harley Davidson to Trek bicycles, many successful businesses were launched out of Wisconsin.

With access to top talent from its public universities to the numerous tax credits available, there are plenty of reasons to start your new business in The Badger State.

And starting a limited liability company (LLC) in Wisconsin is an excellent choice for business owners looking to limit their personal liability.

In this step-by-step guide, we’ll walk you through the steps you’ll take to form your LLC in Wisconsin.

We’ll dig into the pros and cons of selecting Wisconsin for your LLC and answer the most frequently asked questions among new business owners.

Quick step-by-step guide for setting up an LLC in Wisconsin

  1. Step 1: Choose a business name for your Wisconsin LLC
  2. Step 2: Designate a registered agent
  3. Step 3: File the Wisconsin LLC Articles of Organization
  4. Step 4: Get an EIN (Employer Identification Number) from the IRS
  5. Step 5: Prepare an LLC operating agreement
  6. Step 6: Open a Wisconsin business bank account

Step 1: Choose a business name for your LLC

The first aspect of forming your Wisconsin LLC is coming up with a name that complies with Wisconsin’s LLC naming rules.

Generally, there are two requirements in Wisconsin for naming an LLC:

  1. The name must be distinguishable from other LLCs.
  2. The name must contain the words “limited liability company” or “limited liability co” or end with the abbreviation “LLC” or “L.L.C.”

Once you’ve come up with a name, you can complete a name search using the Wisconsin Department of Financial Institutions’ corporate records tool tool to see if it’s already registered.

Wisconsin doesn’t allow multiple companies to use the same legal name. So before you register your LLC, you need to make sure your desired name is available.

Name reservations

If you’ve settled on a name that’s still available in Wisconsin, but you’re not quite ready to submit your LLC formation documents, you can reserve the name for 120 days by submitting a Name Reservation Application and paying a $15 fee.

Reserving a name ensures it’s available when you’re ready to file with the state and prevents other business entities from registering under it.

Trade name

If you plan to use a moniker for your business, Wisconsin encourages you to register this alternate brand name as a “doing business as” (DBA) name. Also known as a fictitious or assumed name, the state of Wisconsin refers to DBA as a “trademark name.”

Using a trademark name makes sense for some companies.

For example, if your LLC’s legal name is generic and you want to use a more descriptive name, a trademark name might be the right choice. An LLC named “Midwest Ventures” operating as a photographer may wish to register the trade name “Madison Wedding Photography.”

Registering a trademark name makes it public knowledge and allows consumers to identify the owner of a business. And like you did when you searched for your business name, you’ll want to confirm that your desired trade name hasn’t been registered yet.

You’ll need to create an account to search the trademark database and also to register your name. Registrations expire after 10 years, and the application fee is $15.

Step 2: Designate a registered agent

All Wisconsin LLCs need a registered agent.

In short, a registered agent is a person or company that’s appointed to accept official and legal documents on behalf of your business entity.

The registered agent can be you, a trusted employee, or someone not directly involved in the business, like an attorney or a registered agent service company.

Generally, the agent must be:

  • A Wisconsin resident with a physical street address in the state. No P.O. boxes allowed
  • Available during regular business hours

You may want to consider using a professional registered agent service. If you operate a business out of your home, you can keep your personal address out of the public records by using a professional service. Likewise, a professional is better suited for handling sensitive service of process documents.

But using a professional comes with a fee. You can expect to pay up to $100 a year for a registered agent company, depending on the service tiers they provide.

Step 3: File the Wisconsin LLC Articles of Organization

After selecting your business name and registered agent, you can file your Wisconsin Articles of Organization with the Department of Financial Institutions (not Secretary of State). It’s the official document that creates your business and allows you to operate in Wisconsin.

Wisconsin moved to electronic applications a few years ago, so you’ll need to submit your application online.

Information you’ll need to submit your Articles of Organization includes:

  • LLC name
  • Registered agent details, including office address
  • Management type (manager or member-managed)
  • LLC member (owner) names and addresses
  • Name of the person completing the application
  • Signature of one of the members
  • $130 filing fee

Wisconsin provides an expedited processing service for an additional $25 fee if you’re in a rush. Expedited requests are completed by the close of business on the first business day following receipt of your application.

Step 4: Get an EIN (Employer Identification Number) from the IRS

After you’ve filed our Articles of Organization, you’ll want to apply for a federal EIN from the Internal Revenue Service (IRS). A federal employer identification number acts as a social security number for your business and helps the tax authorities identify your tax filings.

While LLCs with one member, called single-member LLCs, can generally get by using the member’s social security number as its federal tax identification number, multiple-member LLCs will need an EIN. And although the single-member LLC may not need one, you should consider getting one if you prefer to keep your personal information off company documents.

EINs are necessary for any LLC with employees and will be used to open a company bank account.

Information you’ll need to apply for an EIN includes:

  • Business name and contact information
  • Number of members
  • Reason for applying
  • Date business started
  • Number of employees expected in the next 12 months
  • The principal activity of your business

The good news is that getting an EIN is free, and you can apply online to get your number issued immediately.

Step 5: Prepare an LLC operating agreement

You’re almost finished!

One of the last critical steps you’ll want to complete is to prepare an LLC operating agreement. Even though Wisconsin doesn’t require you to have this document, it’s a good idea to have one drafted.

An operating agreement is a legal agreement that governs how your LLC will be managed. It covers things such as:

  • Percentage ownership
  • Voting rights and responsibilities
  • Powers and responsibilities of members
  • Distribution of profits and losses
  • Admitting new members or removing members

Without an operating agreement in place, your LLC will resemble a sole proprietorship, and you may lose some of the benefits that come with forming an LLC.

And when you don’t have an agreement in place, your business structure will be governed by the default Wisconsin laws that can produce unintended consequences.

Since the agreement creates the basis for operating your business, invest time and money to write it correctly. You can buy customizable templates online for a few hundred dollars, or you could hire a local attorney for $1,000 or more.

Step 6: Open a business bank account

To keep your business finances organized, open a business bank account.

Don’t be fooled into thinking you can use your personal bank account for your business at the beginning. That’s a big no-no.

A business account:

  • Prevents commingling of personal and business money
  • Simplifies record keeping
  • Creates a sense of legitimacy for your business
  • Facilitates tax preparation

Opening a business bank account in Wisconsin means you can choose from a few options.

National banks (e.g., Chase Bank, Wells Fargo)

National banks will probably have numerous branches near you, have a global reach, and may offer more services than smaller local banks.

Community banks or credit unions (e.g., Johnson Bank, Summit Credit Union)

Local banks and credit unions usually have stronger ties to the community and more desire to provide service to local small businesses. So you might find that their requirements for opening accounts or securing a loan are less stringent than the national banks.

Do your research to find the bank that’s right for you. While you might be comfortable using the same bank you personally bank with, check into the requirements for business accounts such as:

  • Minimum required balances. Some banks will charge a fee if you don’t maintain a certain balance.
  • Minimum initial deposits. Some banks may require a large deposit to initially fund an account.
  • Monthly service fees. These can be discounted if you meet certain conditions (e.g., do a fixed number of transactions per month).

And while you might not find an account with no fees, you should be able to find one for less than $20 per month.
