What is a DBA?

A DBA, also known as “Doing Business As,” Trade Name, Assumed Name, or Fictitious Name, is a name used by a business that is different from the business’s legal name. In Wisconsin, a DBA is officially referred to as a Trade Name.

What is a Trade Name registration good for?

A Wisconsin Trade Name registration is used by many Wisconsin businesses to prove the ownership of a business name, logo, etc.

Who needs to register?

It is not a requirement to register a Trade Name in Wisconsin.  Wisconsin State Statute 132.01 provides more information.  Even though it isn’t required by the state, some vendors or banks will require proof of business ownership to open a business bank account, register a merchant account to accept credit cards, and others.

Sole proprietorships and general partnerships are the most common business entity to register for a Trade Name.

The legal name of a sole proprietor or partnership can be the owner’s full first and last name, which can be used without registering.  For example, if Jane Smith starts a business repairing computers operating under Jane Smith, she doesn’t need to register for a Trade Name in Wisconsin.  If Jane decides to name her business Jane’s Computer Repair or even Jane Smith’s Computer Repair, then she may want to register.

Corporations and Limited Liability Companies won’t typically register a Trade Name since a unique entity name is created during the entity formation process.  Some will file for a DBA if they have another business they want to operate under their corporate/LLC umbrella to keep the liability protection without having to form another entity.

Does Wisconsin require a DBA?

It is not mandatory to register a DBA in Wisconsin; however, there are many cases where it is beneficial.

Does a DBA need an EIN?

An EIN or Employer Identification Number (sometimes called a tax ID number) is a unique nine-digit number that some businesses will register for through the Internal Revenue Service (IRS). An EIN is required for partnerships, corporations, multi-member LLCs, or any business that has employees.

Sole proprietorships and single-member LLCs without employees can use the owner’s social security number to identify the business.
There is no cost to get an EIN when registering directly from the IRS.
