There are 3 primary ways you can register a business name in Wisconsin. You can form a separate business entity by starting your business as a Wisconsin LLC or Corporation, or you can file a DBA name (also referred to as a Trademark) if you operate as a sole proprietor or general partnership. For additional legal protection of your business name, you can also file a federal trademark.

You’ll want to finalize and register your business name before completing other registrations required to legally start your business in Wisconsin, such as:

  • Applying for a Wisconsin Tax Account Number with the Wisconsin Department of Revenue (DOR) for collecting sales tax, use tax, and withholding tax
  • Registering with the Wisconsin Department of Workforce Development for Unemployment Insurance tax purposes
  • Obtaining any required professional licenses from the Wisconsin Department of Agriculture, Trade and Consumer Protection or local business licenses from your county, city, or town clerk’s office
  • Getting an FEIN from the IRS
  • Opening a dedicated business bank account

How much does it cost to Register a Business Name in Wisconsin?

The cost to register a Wisconsin business name varies depending on the type of registration:

  • Wisconsin LLC cost: $130
  • Wisconsin Corporation cost: $100
  • Wisconsin DBA cost: $15

1. Check Business Name Availability

Once you’ve developed a good business name, you’ll need to verify that it’s available. You’ll want to ensure that there isn’t another business in Wisconsin using that business name or has a similar name. There are three types of searches we recommended to verify that your desired name is available:

Trademark Search

The first type of search you’ll want to do is a federal trademark search. As a federal-level registration, a trademark is the ultimate form of business name protection. They supersede any local or state-level registration, so you want to verify that the name isn’t trademarked. While trademarks have limitations, if the name is the same or similar to an existing trademark, you’ll want to create a new name.

You can search the U.S. Patent and Trademark Office (USPTO) database by visiting the Trademark Electronic Search System (TESS) page. Be advised that the results provided by the TESS system can be challenging to read and interpret. Alternatively, you can use the Free Trademark Search from Trademark Engine, which provides a more accessible user interface.

Wisconsin Business Name Search

Once you’ve verified that your business name isn’t trademarked, it’s time to verify it’s not registered in Wisconsin. You can complete your search using the Wisconsin Search Corporate Records.

Complete a few searches using wildcard characters or parts of your business name to find any close matches. This is important because if your business name matches another Wisconsin business too closely, it can result in your business name filing being rejected.

Pro Tip: You might see that your name was registered in the past but is now available because the previous business closed or let their name lapse. Even if the name is available now, it’s highly recommended that you choose a new name if it was registered in the past.

This is because the IRS system that issues EINs often has problems with previously issued names that result in what’s known as “EIN Reference Number 101 error”. While you can still get an EIN after this error, it’s a cumbersome process requiring you to call the IRS and fax them paperwork to get your EIN issued. Unless using that name is absolutely necessary for you and you don’t mind the headache it could cause, we recommend generating a new business name.

Website Domain Search

After confirming there’s no trademark issues and you can register your business name in Wisconsin, you should verify that your domain name is available. Even if you don’t have plans to build a website any time soon, you should register your domain name to block competitors from using it. At a minimum, having a domain name will make your business more credible by allowing you to use an email that has your business name.

Domain Name and Business Email

You can use Namecheap to verify if your domain name is available. They also offer a business email service that’s free to try for the first 60 days when you purchase a domain.

2. Choose a Business Structure

The next step in the Wisconsin business name registration process is to choose the legal structure your business will use. The business structure will determine how your business name is registered. When choosing a business structure, you should consider the number of owners your business will have, what type of financing you’ll need, how much personal liability you’re comfortable with, and how your business will be taxed. You can use our guide on How to Choose a Business Structure for more detailed information on making the best choice for your business.

Recommended Business Structure:

We recommend starting as an LLC for most new businesses. LLCs are easy to maintain and have benefits that other structures don’t. They provide liability protection that a sole proprietorship and general partnership don’t and aren’t subject to double taxation like a corporation.

4. File a Trademark (Optional)

Consider filing a trademark to own and control your business name. Trademarking your business name is a great way to protect your brand. A trademark is a federal registration, providing nationwide protection beyond just registering in Wisconsin.

You can apply for a trademark online, but the trademark registration process can be complicated and lengthy. On average, it takes around 7-9 months before a USPTO examining attorney initially reviews an application. As a result, it’s crucial for your initial application to be prepared correctly.

Consider getting assistance from a qualified attorney or a trademark filing service to ensure your application is prepared correctly. This can save you time and the headache of dealing with the filing and response process required to register a trademark.
