How to File a DBA in Maine (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

Filing a DBA in Maine depends on your structure. A sole proprietor or partnership registers an assumed name with the municipal (town or city) clerk where it does business, while an LLC or corporation files a Statement of Intention with the Maine Secretary of State to use an assumed or fictitious name.

What a DBA Is in Maine

A DBA — "doing business as," also called an assumed or fictitious name — lets you operate under a name different from your legal name. For a sole proprietor, the legal name is your personal name; for an LLC or corporation, it is the name on the formation document. A DBA does not create a separate legal entity or change liability; it is simply a registered trade name.

Maine is one of the states that splits DBA registration between the municipal level (for individuals and partnerships) and the state level (for registered entities). Knowing which applies to you is the first step. For the concept generally, see what is a DBA.

DBA for a Sole Proprietor or Partnership

If you run a Maine sole proprietorship or a general partnership and want to use a business name other than your own, you register the assumed name with the clerk of the town or city where you carry on business. Maine law requires this local filing so the public can identify who is behind the trade name. Fees and forms are set by each municipality, so contact your clerk's office.

Because the filing is local, a business operating in several Maine municipalities may need to register in each. This municipal route is separate from any state entity filing. If you later form an LLC, you would then use the state-level process below.

DBA for an LLC or Corporation

A Maine LLC or corporation that wants to operate under a name other than its registered name files a Statement of Intention to Do Business Under an Assumed or Fictitious Name with the Maine Secretary of State, Bureau of Corporations, Elections and Commissions. Foreign entities qualified in Maine use the corresponding foreign assumed-name form. The fee is set by the Secretary of State's schedule.

The assumed name must be distinguishable and cannot imply a different entity type. This state filing keeps the assumed name tied to your entity in the public record. For formation itself, see how to form an LLC in Maine and the how to form an LLC hub.

Choosing and Checking the Name

Before filing, confirm the name is available and not confusingly similar to an existing registered entity or assumed name. For entities, check the Maine business entity search; for a local sole-proprietor DBA, ask the municipal clerk. Avoid words that suggest a corporation or LLC if your business is not one, and avoid restricted terms.

A DBA does not give you exclusive rights to the name. Another business could hold a superior trademark. If the brand matters, run a USPTO clearance and consider federal trademark registration in addition to the DBA.

DBA, EIN, and Taxes

Registering a DBA does not change your tax status. A sole proprietor still reports on Schedule C, and an LLC keeps its default or elected classification. You generally do not need a new EIN just for a DBA; you use the existing EIN (or, for a solo sole proprietor with no employees, your Social Security number). Banks often want to see the DBA registration to open an account in the trade name.

If your DBA business sells taxable goods or services, register for sales tax with Maine Revenue Services under your legal entity, not the DBA. See Maine LLC tax filing and the business tax overview for state tax registration.

Keeping the DBA Current

Maintain your DBA by following the renewal and update rules of the level where you filed. Municipal assumed-name registrations may have their own renewal or update requirements; state assumed-name filings must be amended or withdrawn if the name changes or you stop using it. Keep the registration accurate so the public record matches your operations.

If you close the business or drop the trade name, file the appropriate withdrawal so the record is clean. Combining a properly registered DBA with a compliant entity — correct registered agent, reports, and taxes — keeps your business in good standing. See Maine registered agent for the related entity duty.

Timing, Banking, and Multiple Names

File your DBA before you start using the trade name in public-facing ways, such as signage, invoices, or a bank account. Operating under an unregistered assumed name can create problems with banks and, at the municipal level, may violate local registration rules. Registering first keeps your public identity and your legal record aligned.

Banks are a common reason people file a DBA. To deposit checks made out to a trade name, or to open an account in that name, a bank typically requires proof of the assumed-name registration — municipal for a sole proprietor, or the state Statement of Intention for an entity. Bring the stamped filing when you open the account.

You can hold more than one DBA. A single owner or entity may register several trade names to run distinct brands or lines of business under one legal umbrella. Each name is registered separately, and none creates a new entity or added liability protection. Keep records of which brand maps to which legal owner.

Coordinate the DBA with your tax accounts. The trade name does not get its own EIN or its own tax return; income flows to the underlying legal owner. If your DBA business collects sales tax, register with Maine Revenue Services under the legal entity. See Maine LLC tax filing for state tax registration.

Finally, decide whether a DBA is enough or whether you need a full entity. A DBA is inexpensive and fast but gives no liability shield and no exclusive rights. If protection or a distinct brand matters, pair the DBA with an LLC and a trademark. The DBA and the entity serve different purposes and often work together.

Confirm which filing level applies before you spend time on forms. A sole proprietor or general partnership registers the assumed name with the town or city clerk, while an LLC or corporation files the state Statement of Intention with the Secretary of State. Filing at the wrong level wastes effort and can leave your trade name unregistered where it actually needs to be recorded.

Check the name for conflicts appropriate to your level. For an entity, use the Maine business entity search; for a municipal DBA, ask the clerk about existing local registrations. While a DBA does not grant exclusivity, choosing a name that is already closely associated with another local business invites confusion and potential disputes you can easily avoid.

Coordinate the DBA with banking and licensing. Bring your stamped registration when you open a bank account in the trade name, and reference the legal owner — not the DBA — when you register for sales tax or apply for licenses. The trade name is a label on the underlying owner, so all tax and licensing accounts attach to that legal person or entity.

Revisit the DBA as your business evolves. If you drop the trade name, change it, or convert a sole proprietorship into an LLC, update or withdraw the registration and, where relevant, refile at the entity level. Keeping the public trade-name record aligned with your actual operations avoids gaps and keeps banking and contracts clean.

Frequently Asked Questions

Where do I file a DBA in Maine?

It depends on your structure. A sole proprietor or partnership files an assumed name with the town or city clerk where it does business. An LLC or corporation files a Statement of Intention with the Maine Secretary of State.

Does a Maine DBA protect my business name?

No. A DBA only registers a trade name; it does not grant exclusive rights or trademark protection. For brand protection, consider a federal trademark with the USPTO.

Do I need a new EIN for a Maine DBA?

Generally no. A DBA does not change your tax status, so you use your existing EIN, or your Social Security number if you are a solo sole proprietor with no employees.

Is a DBA the same as forming an LLC in Maine?

No. A DBA is just a trade name and creates no separate entity or liability protection. Forming an LLC requires filing a certificate of formation with the Secretary of State and gives limited liability.

Can two businesses have the same DBA in Maine?

A DBA does not guarantee exclusivity, and municipal and state records are separate. Check the business entity search and consider a trademark if you need exclusive rights to the name.
