Minnesota also requires newspaper publication: After filing with the Secretary of State; must publish for two consecutive issues in a qualified legal newspaper in the county where the principal place of business is located, adding $30 to $60 per issue ($60 to $120 total for two consecutive issues) to the total cost. This page covers the Minnesota-specific filing steps, the DBA vs. LLC decision framework, publication requirements, and renewal procedures. ## What Is a DBA in Minnesota? In Minnesota, the official term for a DBA is a **Assumed Name (DBA)**. A DBA is a registration that allows a person or business entity to operate under a name that is different from their legal name. It does not create a new legal entity, does not provide liability protection, and does not give you trademark rights over the name. It is simply a public disclosure that "this name is being used by this person or entity." Any sole proprietor, partnership, LLC, or corporation that conducts business under a name other than its registered legal name must file a Assumed Name (DBA) in Minnesota. Common uses include freelancers operating under a business name, LLCs running multiple brand lines under one entity, and established businesses launching a new product line under a distinct brand. Before filing, confirm your chosen name is available by searching the Minnesota Secretary of State name database at [sos.state.mn.us](https://sos.state.mn.us). A name search does not reserve the name or prevent someone else from filing it before you. ## DBA vs. LLC -- Do You Need a DBA or an LLC? A DBA and an LLC are not interchangeable. A DBA is a name registration. An LLC is a legal entity. The decision between them depends on what you actually need: - **You only need a business name for branding.** If you are a sole proprietor who wants to market under a trade name and your personal assets are not at significant risk, a DBA is sufficient and costs far less than forming an LLC. - **You need liability protection.** If you are entering contracts, taking on debt, or operating in a field with liability exposure, a DBA gives you none of that protection. An LLC separates your personal assets from business claims. A DBA does not. - **You already have an LLC and want a trade name.** An existing LLC can file a DBA in Minnesota to operate under an additional brand name without forming a second entity. This is often the right answer for multi-brand operations. - **You want to bring in partners or investors.** A DBA has no ownership structure. If you are splitting revenue with partners, taking on investors, or need a formal ownership agreement, you need an LLC or other entity, not a DBA. For a detailed comparison, see our [DBA vs. LLC guide](/planning-a-business/dba-vs-llc). ## When a DBA Is the Right Choice A DBA is not a second-best option. For many businesses, it is exactly the right tool. Use it when: - **You are a freelancer or sole proprietor** who wants to operate under a professional business name without the overhead of forming and maintaining an LLC. - **Your LLC runs multiple brands.** Instead of forming a separate LLC for each product line, one LLC can hold multiple DBA names in Minnesota, keeping accounting and compliance simple. - **You are testing a business concept.** A DBA lets you launch under a brand name quickly and inexpensively before committing to the full cost and ongoing compliance of an LLC. - **You need a trade name to open a business bank account.** Banks require a DBA registration to open an account under a name other than your legal name. A filed DBA certificate satisfies that requirement. ## How to File a DBA in Minnesota ### If You Do It Yourself 1 #### Choose a business name that meets Minnesota's requirements. Your DBA name must be distinguishable from names already on file. It cannot be deceptively similar to an existing registered name. Search the Minnesota Secretary of State name database at [sos.state.mn.us](https://sos.state.mn.us) before filing to confirm availability. A search result showing no match does not guarantee your name is unique -- a filing by another party between your search and your submission will take priority. 2 #### Complete the Certificate of Assumed Name for Minnesota. Download or obtain the Certificate of Assumed Name from the Minnesota Secretary of State (state-level filing online or by mail) at sos.state.mn.us. The form requires your legal name (or LLC name), your DBA name, your business address, and your signature. Online filing is typically available through the state portal. 3 #### Submit your Certificate of Assumed Name and pay the filing fee. Submit the completed form to the Minnesota Secretary of State (state-level filing online or by mail). The filing fee is $50 (online or in-person); $30 (by mail). Processing time is typically Same business day for online filings; 1-2 weeks by mail. Online filings through the state portal are typically processed faster than mail submissions. 4 #### Publish notice in an approved newspaper -- required in Minnesota. After filing your DBA, you must publish notice in a newspaper of general circulation in the county where your business is located. Publication window: **After filing with the Secretary of State; must publish for two consecutive issues in a qualified legal newspaper in the county where the principal place of business is located**. Publication costs range $30 to $60 per issue ($60 to $120 total for two consecutive issues). Contact the newspaper directly to confirm it is an adjudicated paper approved for legal notices in your county. After the final publication, file an affidavit of publication with the County Clerk within **After publication; retain the affidavit of publication returned by the newspaper with business records (no statutory deadline to file the affidavit with the state - retain for your records)**. Failure to file the affidavit within the deadline can invalidate your registration. 5 #### Receive your Assumed Name (DBA) certificate and store it. Once approved, you will receive a stamped Assumed Name (DBA) certificate (or a filed copy for online submissions). Keep the original in a secure location. You will need it to open a business bank account under your trade name, and some vendors and contract counterparties will ask for a copy. Make at least two copies immediately. ## DBA Cost in Minnesota Cost Item Amount Notes State / county filing fee $50 (online or in-person); $30 (by mail) Paid to the filing agency at the time of submission Newspaper publication $30 to $60 per issue ($60 to $120 total for two consecutive issues) Varies by newspaper; contact an adjudicated paper in the county of business Total estimated range $90 (online filing fee $50 + two publication issues at $30 each = $110; mail filing $30 + $60 publication = $90) - $170 (online filing fee $50 + two publication issues at $60 each = $170) Filing fee plus publication; varies by county and newspaper LLC formation (comparison) Varies by state For reference when evaluating DBA vs. LLC The total cost of a Minnesota DBA ranges from $90 (online filing fee $50 + two publication issues at $30 each = $110; mail filing $30 + $60 publication = $90) to $170 (online filing fee $50 + two publication issues at $60 each = $170), combining the $50 (online or in-person); $30 (by mail) filing fee with the $30 to $60 per issue ($60 to $120 total for two consecutive issues) newspaper publication cost. Publication rates vary by county and newspaper, so contact at least two adjudicated papers in your county for quotes before committing. By comparison, forming an MN LLC costs $135 in state fees -- more upfront, but it also creates a legal entity with liability protection that a DBA cannot provide. ## DBA vs. Trademark A common misconception is that filing a DBA protects your business name against others using it. It does not. Here is the actual distinction: - **A DBA registration** gives you the right to operate under that name in the jurisdiction where you filed. It establishes public notice of your use. It does not prevent another business from filing the same or a similar name in a different county, state, or industry. - **A state trademark** provides broader protection within Minnesota, covering your right to use the name or mark in connection with your goods or services against others in the same state who might copy it. State trademark registration is filed with the Minnesota Secretary of State. - **A federal trademark (USPTO)** provides nationwide protection for your brand name, logo, or slogan. It is the strongest form of name protection available and blocks competitors in all 50 states from using a confusingly similar mark in the same industry. - **Bottom line:** If your business name is a meaningful part of your brand value, a DBA alone is not enough. Pursue a federal trademark through the USPTO. LLC Attorney offers trademark filing services for businesses that need brand protection beyond a name registration. ## What You Can Do With a MN DBA Name A registered Assumed Name (DBA) in Minnesota allows you to: - **Open a business bank account** under your trade name. Banks require a filed DBA certificate to open an account in a name other than your legal name or LLC name. - **Accept checks and payments** made out to your business name rather than your personal name, creating a cleaner separation of business finances. - **Enter contracts under your trade name.** You can sign agreements, leases, and vendor contracts using your DBA name, with the underlying legal entity (you personally, or your LLC) as the actual contracting party. - **Market and advertise** under a brand name that is more descriptive, memorable, or marketable than your legal name. What a DBA does not allow: forming a legally distinct entity, shielding personal assets from liability, or giving you exclusive rights to the name in other states or jurisdictions. ## DBA for an Existing MN LLC An existing Minnesota LLC that wants to operate under a brand name different from its registered LLC name must file a Assumed Name (DBA) with the Minnesota Secretary of State (state-level filing online or by mail). The LLC remains the legal entity of record for all purposes -- taxes, contracts, and liability. The DBA is simply the name presented to the public. For example: "Sunrise Ventures LLC" files a Assumed Name (DBA) for "Blue Sky Cleaning Services." The LLC enters all contracts, pays all taxes, and holds all licenses. Customers see "Blue Sky Cleaning Services." Both are correct -- they refer to the same legal entity operating under two names. This approach is more efficient than forming a second LLC for each brand, because it avoids duplicate formation fees, separate registered agents, separate operating agreements, and multiple annual report filings. One LLC can hold as many DBA names as needed. ## DBA-to-LLC Conversion Path A DBA is often the right starting point, but there is a logical progression many businesses follow as they grow. Here is the typical four-stage path: 1. **Start as a sole proprietor with a DBA.** Low cost, minimal compliance, fast to launch. You are personally liable for everything, but when you are just testing a concept, that risk may be acceptable. 2. **Approach the revenue threshold.** When revenue approaches $50,000 per year, the liability exposure of a sole proprietorship starts to outweigh the cost savings of avoiding LLC formation. Business debt, employee claims, and contract disputes become real risks to personal assets. 3. **Form the LLC and transfer the DBA.** File an MN LLC with the Secretary of State. After formation, either file a new Assumed Name (DBA) in the LLC name (the LLC becomes the holder of the trade name) or file an amendment to the existing DBA to reassign it to the LLC. 4. **Run the DBA under the LLC umbrella.** The LLC becomes the entity of record for all legal, tax, and financial purposes. The DBA continues as the customer-facing brand name. If your business later expands to multiple states, each state where you operate may require a separate DBA or foreign qualification filing. Forming the MN LLC costs $135 in state fees. LLC Attorney handles the LLC formation, the operating agreement, and the transition of your DBA filing in a single process. ## DBA Renewal in Minnesota Minnesota Assumed Name (DBA) registrations must be renewed annual renewal required by december 31 each year; no fee for annual renewal when filed on time. Renewal is filed with the Minnesota Secretary of State (state-level filing online or by mail) before the expiration date. If you renew on time with no changes to the registration, republication in a newspaper is not required. Republication is only triggered if you renew after expiration or if any information on the registration has changed. Set a calendar reminder at least 60 days before the expiration date to avoid a lapse in your registration. Operating under an expired DBA registration can expose your business to legal complications and may affect your ability to open or maintain business bank accounts. ## When to Consult an Attorney Most DBA filings are straightforward and do not require an attorney. But professional guidance is worth considering in these situations: - **Your chosen name is close to an existing brand.** If the name you want to register as a DBA resembles a federally trademarked brand, you could face a cease-and-desist even after filing. An attorney can assess likelihood of confusion before you invest in marketing. - **You are operating across multiple states.** If your business uses a DBA in more than one state, each state has different rules. An attorney can advise whether you need separate filings or whether a different entity structure makes more sense. - **You are transitioning from a DBA to an LLC.** The conversion is more than just forming an entity. Existing contracts, bank accounts, and vendor agreements may need to be updated. An attorney ensures the transition does not leave gaps in your legal standing. - **You have a co-owner.** A DBA has no built-in ownership structure. If you and a partner share a business operating under a DBA, a dispute about ownership or revenue division has no legal framework to fall back on. An LLC with an operating agreement fixes that. In Minnesota, the state-level filing is centralized, which reduces complexity. But if your business has any of the characteristics listed above, an attorney consult is worth the investment before you commit to a name or entity structure. LLC Attorney offers flat-fee attorney consultations in 30-minute increments with no retainer. You can speak with a licensed attorney about your specific Minnesota situation before filing. ## Compare DBA Requirements in Nearby States State Filing Level Fee Publication Renewal Minnesota (MN) State $50 (online or in-person); $30 (by mail) Yes Annual renewal required by December 31 each year; no fee for annual renewal when filed on time Wisconsin State (Wisconsin Department of Financial Institutions) $15 No Every 10 years ($15 renewal fee) Iowa State (Iowa Secretary of State via Fast Track Filing portal; sole proprietors and general partnerships file with the county recorder) $5 No No renewal required - Iowa fictitious name registrations do not expire DBA requirements vary significantly by state.

If your business operates in more than one state, you will need to comply with each state's rules separately. A federal trademark registration is the only mechanism that provides nationwide name protection in a single filing. ## Minnesota DBA: Special Requirements Key Minnesota-Specific Requirement Minnesota requires newspaper publication after filing your Assumed Name (DBA). You must publish once per week for the required period (After filing with the Secretary of State; must publish for two consecutive issues in a qualified legal newspaper in the county where the principal place of business is located) and file an affidavit of publication with the filing agency within After publication; retain the affidavit of publication returned by the newspaper with business records (no statutory deadline to file the affidavit with the state - retain for your records). Failure to complete publication can invalidate your registration. **Publication window:** After filing with the Secretary of State; must publish for two consecutive issues in a qualified legal newspaper in the county where the principal place of business is located. **Affidavit deadline:** After publication; retain the affidavit of publication returned by the newspaper with business records (no statutory deadline to file the affidavit with the state - retain for your records). The affidavit must be filed with the County Clerk, not just the newspaper. This step is often missed by self-filers and can result in an invalid registration. **Republication on renewal:** No - publication is a one-time requirement at initial filing; annual renewal does not require republication. Review your county's specific renewal rules before your expiration date to confirm whether publication will be required again. Verification date for the data on this page: June 2026. Requirements change. Always confirm current fees and procedures with the Minnesota Secretary of State (state-level filing online or by mail) before filing. ## Frequently Asked Questions What is a DBA called in Minnesota? ![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75) In Minnesota, a DBA is officially called a Assumed Name (DBA).

A DBA is a registration of use, not an intellectual property protection. If you want exclusive rights to your business name as a brand, you must file a federal trademark with the USPTO separately. Can an LLC use a DBA name in Minnesota? ![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75) Yes. An existing Minnesota LLC can file a Assumed Name (DBA) to operate under a name different from its legal LLC name. This is common when an LLC wants to run multiple product lines or brands under one legal entity. The LLC remains the legal entity of record; the DBA is the operating name used with customers, vendors, and banks. Do I need a separate EIN for my DBA in Minnesota? ![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75) No. A DBA is not a separate legal entity and does not require its own EIN.

If your DBA is operated by an LLC or corporation, the entity's existing EIN covers the DBA.

Is a DBA the same as an LLC in Minnesota? ![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75) No. A DBA is just a name registration, not a legal entity. It provides no liability protection. An LLC is a separate legal entity that shields your personal assets from most business liabilities. If you are a sole proprietor using a DBA, you remain personally responsible for all business debts and lawsuits. Forming an LLC in Minnesota costs $135 in state fees and creates a genuine liability barrier. When should I convert my Minnesota DBA to an LLC? ![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75) Consider converting your DBA to an LLC when your business revenue approaches $50,000 per year, when you take on business debt, when you hire employees, or when you enter into significant contracts. At those thresholds, the personal liability exposure of operating as a sole proprietor under a DBA becomes a real financial risk. Forming an Minnesota LLC costs $135 in state fees and takes effect from the formation date. ## Outgrown Your DBA? Form a Minnesota LLC A Assumed Name (DBA) gets you a business name, but it offers no liability protection and no separation between your personal assets and your business. If your revenue is approaching $50,000 per year, if you are taking on employees, or if you are entering contracts where a lawsuit is a real possibility, a Minnesota LLC is the logical next step. The Assumed Name (DBA) registration process is also a good moment to evaluate whether the business you are building warrants a proper legal structure from the start. LLC Attorney forms Minnesota LLCs — including a professionally drafted operating agreement. The state filing fee is $135. You get a separate legal entity, a liability barrier, and a foundation that can accommodate partners, investors, and growth — none of which a DBA provides.
