How to Register an Assumed Name in Minnesota

Last Updated on

Quick Reference

In Minnesota, a business operating under a fictitious name will need to register a DBA.  Learn more about what a DBA is, who needs one and how to register.

What is an Assumed Name?

An Assumed Name, commonly referred to as a DBA or “Doing Business As”, Trade Name, or Fictitious Name is a name used by a business, that is different from the legal name of the business.

When a business wants to operate under a name other than their legal name, the state of Minnesota, like most states, requires the business to register their business name.  The registration requirement was designed to protect consumers from business owners hiding anonymously behind the name of a business.

Who needs to register?

The requirements and need to register for an Assumed Name vary, depending on the type of business entity.

Sole proprietorships and general partnerships are the most common entities to register for a DBA.

The legal name of a sole proprietor can be the owner’s full first and last name or the full name of each partner, which can be used without registering.  For example, if John Smith starts a business repairing computers but doesn’t use a business name he doesn’t have to register.  If John decides to name his business John’s Computer Repair then he will need to register.

Corporations and Limited Liability Companies won’t typically register a fictitious name since a unique entity name is created during the 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.

Minnesota DBA Registration Form

The Assumed Name form is available on the Secretary of State’s website at  There is both a PDF form that can be mailed in or registration can be done online.

How much does it cost to register?

The DBA has to be renewed annually, however, there is no cost to do so.

Step 4 – Publish the Legal Notice
 After filing the Certificate of Assumed Name Registration (of which there is no longer a physical certificate provided), a legal notice must be published.  This notice is published in the legal section of a qualified newspaper that has circulation in the county where the principal office is located for two consecutive issues.

Step 5 – Obtain the Affidavit
After the ad runs, the newspaper will provide an affidavit proving the ad ran along with the notice.  These items must be saved by the business owner.

Upon the filing of a “Certificate of Assumed Name”, there is no certificate issued. The approved form that you will receive back; is proof that your certificate of Assumed Name has been filed with our office.

Name Restrictions

DBAs can’t be registered using words that are related to banking with words such as bank, banker, savings, trust, credit union and insurance.

Additionally, DBAs cant use entity designators such as Incorporation, Corp, Limited Liability Company, LLC, etc unless the entity is registered as that entity.

Protecting your business name

While registering your Assumed Name will keep someone else from registering the exact same name in Minnesota, it does very little from someone else operating a business under that name in other states.  If stopping anyone from using your business name is important, you can protect it through a trademark – See how to protect your name through a trademark.
