Does a Massachusetts DBA give me a separate business or liability protection?

No. A business certificate is only a registered trade name. It does not create a separate legal entity and gives no liability protection. For a liability shield you would form an LLC or corporation with the Secretary of the Commonwealth.

Massachusetts DBA Filing: Business Certificate Cost (2026)

Q: What is a DBA in Massachusetts?

In Massachusetts a DBA is called a business certificate, filed under M.G.L. c.110, §5 with the clerk of the city or town where the business has a place of business. It registers a trade name that differs from the owner's or entity's legal name. It is not filed with the Secretary of the Commonwealth.

Q: Where do I file a DBA in Massachusetts?

You file a business certificate with the city or town clerk in each municipality where you conduct business under the name. Because it is a local filing, the exact form, fee, and process are set by that city or town, and there is no statewide DBA registry.

Q: How much does a Massachusetts DBA cost?

Fees are set by each city or town and commonly run from about $30 to $65 for the initial business certificate. For example, the City of Boston charges $65. Confirm the current fee with your city or town clerk, since amounts vary widely.

Q: How long does a Massachusetts business certificate last?

A Massachusetts business certificate is valid for four years from the date of filing under M.G.L. c.110, §5. You must file a renewal to keep using the name, and file a statement of change or discontinuance if the facts change or you stop using the name.

What a Massachusetts DBA Is

A DBA ("doing business as") is a trade name a business uses that differs from the owner's legal name. Massachusetts's statutory term for it is a business certificate, governed by Massachusetts General Laws Chapter 110, Section 5. A sole proprietor named Maria Lopez who operates as "Bloom Street Bakery," or an LLC that markets a brand different from its exact registered name, generally needs a business certificate on file. Filing publicly links the trade name to the true owner so customers and creditors can identify who stands behind the business. For the national concept, see what is a DBA.

Importantly, a DBA is not a business entity. It provides no liability protection and does not change how you are taxed. If you want a liability shield, you form an LLC or corporation with the Massachusetts Secretary of the Commonwealth instead - a separate process from a business certificate filing, and one you can verify later on the Massachusetts business entity search.

Who Must File a Business Certificate

Under M.G.L. c.110, §5, you generally must file a business certificate when:

A sole proprietor or partnership conducts business under any title other than the real name of each person operating the business.
An LLC or corporation conducts business under a name that is not the exact name on its Certificate of Organization or corporate Articles of Organization.

You must file in each city or town where the business has an office or place of business under the name - so a shop with locations in two towns files in both. Banks also commonly require a filed, stamped business certificate before they will open an account in the trade name, so most owners file early. The clerk keeps the certificate on public record.

Where and How to File Step by Step

Because business certificates are municipal filings, exact steps vary, but the pattern is consistent statewide:

Identify the right clerk. File with the clerk of each city or town where you have a place of business under the name.
Search the local index. Many clerks let you check whether the name is already registered in that municipality.
Complete the business certificate. List the business name, the address of the place of business, and the full name and residential address of each owner.
Sign before the clerk or a notary. Massachusetts business certificates typically must be signed in person at the clerk's office or notarized, depending on the municipality.
Pay the local fee and keep the stamped certificate with your records; a bank will ask for it.

Unlike some states, Massachusetts does not require newspaper publication of a business certificate - the local filing itself provides the public notice. See the national DBA overview for how this compares with other states.

Massachusetts DBA Fees (2026)

Business certificate fees are set by each of Massachusetts's 351 cities and towns, so there is no single statewide amount. The table gives the typical structure; confirm exact figures with your city or town clerk before filing.

Item	Typical amount (2026)	Set by
Business certificate (initial filing)	About $30–$65 (Boston $65)	City or town clerk
Renewal (every 4 years)	Similar to the initial filing fee	City or town clerk
Statement of change / discontinuance	Small local fee	City or town clerk
Certified copy of the certificate	Small per-copy fee	City or town clerk
Additional municipality (extra location)	Full fee again in that city/town	City or town clerk

Because amounts differ by municipality, this guide does not quote a single statewide fee; the city or town clerk's published fee schedule is the authoritative source. For example, the City of Boston posts its business certificate process and $65 fee online, while smaller towns often charge less.

Term, Renewal, and Changes

A Massachusetts business certificate is valid for four years from the date of filing. To keep the name, you file a renewal before it expires. If you change the business name, address, or ownership, or you stop using the name, you must file a statement of change or a statement of discontinuance with the same clerk, generally within a short window after the change. Keeping the certificate current matters because a lapsed or inaccurate certificate can complicate opening or maintaining a business bank account under the trade name.

Penalties for Not Filing

Failing to file a required business certificate is not just a paperwork gap. Under M.G.L. c.110, §5, a person who conducts business under a name without the required certificate can be subject to a fine of up to $300, and enforcement is handled at the local level. Beyond the fine, operating under an unregistered name can make it harder to enforce contracts signed under that name, open a bank account, or qualify for local permits. Filing promptly avoids all of these problems and is inexpensive relative to the risk.

DBA vs LLC, EIN, and Trademark

A DBA is often confused with three other things. It is not a Massachusetts LLC, which is a liability-protected entity filed with the state. It does not require a new EIN - a sole proprietor can use an existing EIN or Social Security number, and an LLC keeps its own EIN, because a DBA is just a name. And it is not a trademark: filing a business certificate with a city or town gives no exclusive statewide or nationwide rights to the name. To confirm entity names registered with the state, use the Massachusetts business entity search; separately, you may still need a local business license and, if you sell taxable goods, a sales and use tax registration through MassTaxConnect.
