Start an LLC in Wisconsin

Step one in forming an LLC is choosing its legal name. You can’t pick a name that’s already been registered in Wisconsin, so you’ll need to research your name by performing a Corporate Records Search.

Wisconsin LLC naming requirements
Wisconsin’s rules for LLC names are outlined in WI ST § 183.0112. The name of your LLC must:

• Include an identifier like “limited liability company,” “L.L.C,” or “LLC.”
• Not include words that suggest that your business is a different entity type, like “partnership” or “corporation.”
• Be unique among other registered Wisconsin businesses.

Reserving a business name in Wisconsin
If your business name available but you’re not ready to register your LLC,  you can reserve your desired LLC name for up to 120 days by filing a Name Reservation Application ($15) with the state.

Getting a DBA “Doing Business As” name
A Wisconsin DBA is any name your business operates under that is not its legal business name. Wisconsin calls DBAs “trade names,” and you can get one for $15 by applying online or by filing a paper form in person with Wisconsin’s DFI. Trade names last for 10 years and are treated similarly to trademarks in Wisconsin. Check out our DIY guide to getting a Wisconsin DBA.

Reserving a domain name
A domain name is the address of your website. For example, our domain name is “northwestregisteredagent.com.” Reserving a domain as soon as possible allows you to make certain the name you want is available as a business and domain name. Domain registration can be tricky, but when you hire us to form your Wisconsin LLC, we’ll help you get a domain name totally free for the first year.

Trademarking your WI LLC name
You may think that registering an LLC in Wisconsin means that no one else can use your business name, but that’s not always the case. If another business decides to use your LLC name, there’s not much you can do unless you register a trademark. It costs $15 to register a trademark in Wisconsin (online or in person filings only), and your mark will last 10 years before it needs to be renewed. If you want a stronger legal claim to your LLC name, register a federal trademark and protect your name on the national level.

Your registered agent is a person or business that accepts legal and state mail on behalf of your LLC. Wisconsin requires all LLCs to appoint a registered agent. Your registered agent can be you, someone associated with the business, or a third party like a professional registered agent service.

Your registered agent’s name and address must be listed on your Articles of Organization, so you’ll need to appoint one before officially forming your LLC.

WI registered agent requirements
Your Wisconsin registered agent must meet the requirements outlined in WI ST § 183.0115. At minimum, your registered agent must:

• Have a physical address in the state (no PO Boxes).
• Be present at that address during regular business hours (9am to 5pm).
• Agree to accept service of process on behalf of your LLC.

Using a registered agent service
Here are three reasons why hiring a registered agent service is a smart move:

1. Privacy. If you act as your own registered agent, your name and address will end up on Wisconsin public record. This is a bad idea if you value your privacy. A professional registered agent (like Northwest) will let you list their name and business address on all Wisconsin LLC filings where it’s allowed, helping to keep your personal information away from prying eyes.

2. Peace of mind. With Northwest, you’ll never have to worry about time-sensitive legal or state mail going unanswered because you were on vacation or out of the office. No matter where you are, we’ll notify you the same day your mail arrives.

3. Protect your image. Business can get messy. If you run into legal problems, you won’t want to get served in front of your customers or employees. A registered agent service will make sure this never happens.

To officially form your Wisconsin LLC, you’ll need to complete the Wisconsin Articles of Organization.

Below is the information you’ll need to file your Wisconsin Articles:

Required:

• Company name. Include an indicator like “LLC” or “limited liability company.”
• Registered agent. The person or company designated to accept legal documents on behalf of your business.
• Registered agent address. This must be a street address. This address will go on public record.
• Management structure. Specify whether members or managers will run your LLC.
• Organizer. This is the person filing the document. You must include the organizer’s name, signature, address, and daytime phone number. This goes on public record.

Optional:

• Effective date. You can delay your LLC’s start date up to 90 days in the future, or skip this part to start your LLC right away.

How do I file the Wisconsin Articles of Organization?

Member-managed vs. manager-managed LLC
In member-managed LLCs, the members (owners) are in charge of the day-to-day operations. In manager-managed LLCs, members hire managers to take on regular business tasks like hiring and firing employees, dealing with vendors, managing credit and bank accounts, and signing agreements and contracts.

Wisconsin does not require LLCs to have an operating agreement, but you’d be wise to write one. That’s because your LLC’s operating agreement acts as a guide for every scenario your business is likely to face. While you can customize your agreement to fit your LLC’s needs, it should focus on big-picture issues like:

• initial investments
• distribution of profits and loses
• removing or adding members
• selling or dissolving the LLC

Drawing up an operating agreement can be daunting. Get started with our attorney-approved Wisconsin Operating Agreement template.

An EIN—or employer identification number—is a unique nine-digit number assigned to businesses by the IRS. You’ll need an EIN if you have a multi-member LLC or to pay any employees your LLC might hire. You can get your EIN for free from the IRS. Or keep things simple and hire us, and we’ll get your EIN for you.

The Beneficial Ownership Information (BOI) Report became a requirement for most LLCs in January 2024. The purpose of the BOI Report is to combat money laundering and other financial crimes. You’ll need to disclose identifying information about your company applicant and all beneficial owners to the Financial Crimes Enforcement Network (FinCEN). BOI Reports can be filed for free through the FinCEN.gov website. Can’t stomach another filing? Hire us to file for you for just $9.

You can see the finish line, but there’s still a few more things you’ll need to do in order to maintain your Wisconsin LLC. We go over them here:

Opening a business bank account
If you mix your personal and business finances, LLC members assets could be vulnerable to a lawsuit or bankruptcy. A court could find that the owners of the LLC and the business itself are not separate entities because they didn’t take the step to separate finances. That’s why opening a business bank account is a must.

To open a business bank account you’ll need a copy of your Wisconsin Articles of Organization, your LLC’s EIN, the operating agreement, and if your LLC has multiple members, an LLC Resolution to Open a Bank Account.

Wisconsin LLC tax requirements
Wisconsin LLCs are taxed as pass-through entities by default. This means the LLC itself is not taxed. Instead the profits “pass through” the business to the owners, who report the profits as income on their individual tax returns. LLC profits are taxed at the federal self-employment tax rate (15.3%).

Licenses and permits
If your LLC will be making sales in Wisconsin, you’ll need to apply for a Business Tax Registration (BTR) application, which lets your business collect and remit sales tax to the state. The BTR application can be printed and filed by mail or submitted online with Wisconsin’s Department of Revenue. The BTR license costs $20 and lasts for two years, then $10 every two years afterwards.

Depending on the industry your business is involved in, you may also need to apply for other tax permits such as food and beverage sales, lodging, vehicle rentals, or even professional licenses if your LLC will be involved in highly regulated fields like engineering or health care.

Wisconsin Annual Report
Each year your Wisconsin LLC will be required to file a Wisconsin Annual Report with the DFI. The annual report acts as a yearly check-in with the state where your business confirms or alerts the state to any changes with your LLC (ex: change in address). The reports costs $25 and can be filed online with Wisconsin’s One Stop Business Portal (add $1 for online processing) or by mail with a paper form.

Annual reports are filed every year, starting the year after the LLC was formed. The report due date is based on the time of year the LLC was formed:
