An assumed name is a DBA (doing business as) in Michigan. Obtaining a Michigan DBA registration will not safeguard your personal assets. Forming a formal business structure, such as an LLC or corporation, will provide you with liability protection as well as a business name.
To begin with a Michigan DBA, select your business entity type:
Partnership or sole proprietorship (if your business is not a formal structure)
Corporation, LLC, or LLP (if your business has a formal structure such as LLC or corporation)
Fill out a Michigan DBA application for a sole proprietorship or general partnership.
General partnerships and sole proprietors must register their Michigan DBA with the County Clerk in the county in which their business is located. Estates and real estate investment trusts must also register with the county.
A general partnership is a company formed by two or more people that does not have a formal business structure. A sole proprietorship is an unincorporated business owned by a single person. In either case, the business name is the same as the owners’ names. In these cases, a DBA can be useful for changing the business name to a more marketable name.
A DBA is only used for branding purposes. A DBA does not protect your personal assets in the event that your company is sued. As a result, we strongly advise that a DBA be used only by a formal business structure such as an LLC or corporation to add new brands to an existing business.
If you run an informal business (sole proprietorship or partnership), we strongly advise you to form an LLC to keep your business and personal assets separate. The name of the LLC can be chosen to serve as the business’s brand name.
Step 1: Conduct a Michigan Assumed Name Search.
Michigan assumed names must be distinct and meet the state’s business name requirements.
To begin, go to the website of the Michigan Department of Licensing and Regulatory Affairs and search for your new DBA name to ensure it isn’t already in use.
Review the Michigan naming requirements next. In Michigan, assumed names should NOT include the following words:
Words that may cause confusion between your company and a government agency (FBI, Treasury, State Department, etc.)
Without approval, the words “bank,” “industrial bank,” “deposit,” “surety,” “security,” “trust,” or “trust company” or other words implying that the corporation is a banking, insurance, surety, or trust company
Other restricted words that have not been approved
We recommend that you check to see if your name is available as a web domain (URL). You may not intend to launch a business website right now, but you may want to prevent others from acquiring your URL.
Step 2: File a DBA with the County Clerk in Michigan.
To operate under a DBA, sole proprietors and partnerships must file a Certificate of Persons Conducting Business Under Assumed Name with the appropriate county clerk’s office(s).
Sole proprietors and partnerships must file in any county where they conduct or transact business.
