What is a DBA?

If a business wants to operate with a different name than the one used to form the business, it may have to register the new name (called a trade name or fictitious name). This process is often called filing for a DBA or doing business as. For example, if “Frank’s Hot Dogs LLC” wants to do business as “Best Hot Dogs in Town,” then the owners have to file a DBA.

When you need a DBA

Wisconsin law requires all businesses to file a DBA when they are using a fictitious business name. Despite being the law, filing for a DBA also allows the company to open bank accounts, write contracts, and otherwise operate using the fictitious name.

Setting up a DBA in Wisconsin

Start the process by checking to see if the name you want is available. Be aware of some requirements for business names in Wisconsin, including: The name used may not include the flag, coat of arms, or insignia of the United States of America, or of any state or municipality, or any foreign nation.

The name must be distinguishable from other registered DBAs.

For corporations, the name must be distinguishable not only from other DBAs but from a variety of different businesses operating within the state of Wisconsin. Check with the Wisconsin Secretary of State for more details.

Wisconsin filing and registration

When completing the paperwork to file your DBA, you will need to provide the name of the business entity as it was originally formed, the proposed DBA to be registered, the principal place of business of the entity in question, and the general purpose of the business.

Tax considerations

Getting a trade name registered by filing a DBA doesn’t change how your company is taxed.

Joe was extraordinary

Joe was extraordinary! I called to add a DBA to my existing LLC, and he got straight to the point with exactly what I needed. He went above and beyond by taking the time to answer my questions thoroughly and even checked my account. He pointed out a couple of things for me to review, and if that wasn’t enough, he even sent me a screenshot so I knew exactly what he was referring to. Wow—what an asset to your company! Loyal customer here!
