If you want to run your business under a trade name, you need to understand how DBA registration in Minnesota works. As of January 2026, Minnesota state law requires most businesses operating under a name other than their legal name to formally register what the state officially calls an “Assumed Name.” Whether you are a sole proprietor, a partnership, or an LLC looking to rebrand, this complete guide covers every step from naming rules to renewal deadlines, so you stay compliant and move forward with confidence.

What Does “Doing Business As” Actually Mean in Minnesota?

Before filing, understand what a DBA is  and what it is not:

• A DBA is not a separate legal business entity
• It does not provide personal liability protection
• It does not function as a trademark or grant name exclusivity
• It is simply a registered trade name that lets you operate and collect payments under a chosen name
• Minnesota officially uses the term “Assumed Name” rather than DBA

Important: Registering a DBA in Minnesota does not stop another business from registering the same assumed name. For brand exclusivity, consider a federal trademark through the USPTO.

What Makes Minnesota DBA Registration Unique?

Here is what sets DBA Minnesota apart from other states:

Feature	Details
Registration required	Yes, mandated by Minnesota state law
Registration exceptions	Some licensed professionals may be exempt
Annual renewal	Yes, mandatory every year
Publication requirement	Yes, must publish in a qualifying legal newspaper

Who Needs a DBA in Minnesota?

• A sole proprietor operating under any name other than your own legal name
• A general partnership using a trade or business name
• An LLC or corporation marketing or selling under a different brand name
• An existing business expanding into a new market or rebranding

Top Reasons to Get a DBA in Minnesota

Minnesota DBA Naming Rules: What You Can and Can’t Use

Minnesota enforces specific naming restrictions you must follow before filing:

Prohibited or restricted names include:

• Names implying government affiliation, such as “Federal” or “National,” without approval
• Names identical or deceptively similar to an already registered business
• Names suggesting a licensed profession like “Bank” or “Insurance” without proper licensing

Tips for choosing a compliant name:

• Run a name availability search before committing
• Avoid words that could mislead consumers about your business authority
• Conduct a separate USPTO search if trademark protection is a priority

How to Register a DBA in Minnesota: Step-by-Step

Step 1: Search name availability: Use the Minnesota Secretary of State’s online business name search tool to verify your name is not already taken.
Step 2: Confirm naming compliance: Make sure your chosen name complies with all Minnesota assumed-name rules.
Step 3: Determine where to file: Identify whether you file at the county level or with the Minnesota Secretary of State based on your business structure.
Step 4: Complete the Certificate of Assumed Name: Fill out the correct form for your filing level, state, or county.
Step 5: Pay the filing fee: Submit payment with your completed form.
Step 6: Publish your certificate in a legal newspaper: Minnesota law requires publication in a qualifying legal newspaper after filing.
Step 7: Retain proof of publication: Keep your affidavit of publication on file as proof of compliance.

Where to File Your Minnesota DBA: County vs. State Filing

Filing at the wrong level is one of the most common and costly mistakes in DBA registration in Minnesota.

Business Type	Where to File
Sole proprietors	County where the business is located
General partnerships	County where the business is located
LLCs	Minnesota Secretary of State
Corporations	Minnesota Secretary of State

Major county filing offices include Hennepin, Ramsey, Dakota, Anoka, and Washington counties. Always confirm the specific process with your local county office, as procedures vary.

Minnesota DBA Publication Requirement: What You Must Do After Filing

Minnesota’s publication requirement is one of the most overlooked steps in the entire process:

• The newspaper must be officially designated as a legal newspaper under Minnesota law
• Publication is required once per week for two consecutive weeks
• Publication must be in the county where your principal place of business is located
• You will receive an affidavit of publication. Keep this document permanently
• Skipping this step can result in your registration being considered non-compliant

Tax Considerations for Your Minnesota DBA

• A DBA does not change your federal or Minnesota state tax structure
• You do not need a separate EIN solely for a DBA
• Sole proprietors report all DBA income on their personal return using Schedule C
• LLCs with a DBA continue to be taxed according to their original entity election
• Register for a Minnesota sales tax permit if selling taxable goods or services
• Always consult a licensed tax professional for advice specific to your situation

How to Renew Your Minnesota DBA

• Renewal is due every year from your original registration date
• State filers renew through the Minnesota Secretary of State website
• County filers renew through their county office
• Missing the deadline may cause your assumed name to lapse
• Set a calendar reminder 60 days before your renewal date to avoid any compliance gap

How to Amend or Cancel a Minnesota DBA

To amend: File an amendment form with the Secretary of State or your county office if your address, ownership, or name details change.

To cancel: File a cancellation form at the same level where you originally registered. Once processed, your assumed name will no longer be active.

You can legally sign contracts under your DBA name as long as it remains active and registered.
