Massachusetts business license guide
Last checked: April 26, 2026
Massachusetts does not make most small businesses follow one simple “business license” path.
The state points business owners to separate steps: choose a structure, file with the Secretary of the Commonwealth if needed, get a city or town business certificate if using another name, register through MassTaxConnect when taxes apply, and check local zoning and industry permits.
The short answer
Most Massachusetts businesses should not start by searching for one statewide “business license.” Start with your business structure, your business name, your city or town, your tax duties, and your industry.
Massachusetts uses several separate systems. A corporation or LLC files with the Secretary of the Commonwealth, Corporations Division. A business using a name different from its legal name may need a local business certificate, also called a DBA. A business that collects or pays Massachusetts taxes may need MassTaxConnect. Local zoning, health, fire, building, and industry rules may still apply.
Important: A Massachusetts business certificate is not the same thing as a business license. Mass.gov says the certificate creates a public record of the business owner’s name and address. It does not replace tax registration, zoning approval, a health permit, a professional license, or a local operating permit.
Massachusetts facts to know first
| Question | Massachusetts answer | Where to check |
|---|---|---|
| Is there one statewide general business license? | Massachusetts does not send every business to one single statewide general business-license application. The official start page points to separate steps based on structure, name, taxes, local rules, and industry. | Mass.gov starting a business page |
| What is a DBA called? | Massachusetts commonly calls it a business certificate or DBA. It is filed with the city or town where the business is located when the business operates under a name different from its legal name. | Mass.gov business certificates page |
| Who handles LLCs and corporations? | The Secretary of the Commonwealth, Corporations Division handles many entity filings for LLCs, corporations, partnerships, and foreign entities. | Corporations Division |
| What is the state tax portal? | Massachusetts uses MassTaxConnect for many Department of Revenue business tax accounts, filings, and payments. | Register with MassTaxConnect |
| What is the sales tax registration called? | DOR refers to a Sales and Use Tax Registration Certificate. After registration, Form ST-1 is issued for each business location and must be displayed where customers can see it. | Massachusetts sales and use tax guide |
| Who handles many professional licenses? | The Division of Occupational Licensure regulates many trades and professions through boards and online portals such as ePLACE and eLIPSE. | DOL license check |
Quick-start checklist for Massachusetts
Use this order if you are starting from zero. Your exact steps may change based on your city, business type, products, employees, and location.
- Write down your exact business activity. Example: online handmade product sales, home bakery, landscaping, contractor work, consulting, short-term rental, restaurant, salon, daycare, cannabis, alcohol, or transportation.
- Choose your structure. Sole proprietorships and general partnerships have different steps than LLCs and corporations.
- Check the business name. Search the Secretary of the Commonwealth business database if forming or registering an entity. Also check your city or town business certificate process if using a DBA.
- File with the Secretary of the Commonwealth if your structure requires it. LLCs, corporations, and some partnerships usually file at the state level. Sole proprietors and general partnerships usually do not file entity formation documents with the Secretary.
- Check whether you need a city or town business certificate. If you use a name different from your legal name, Massachusetts generally treats this as a local business certificate issue.
- Register with MassTaxConnect if your tax situation requires it. This may include sales and use tax, meals tax, withholding tax, room occupancy excise, corporate excise, or other business taxes.
- Check your local zoning, occupancy, building, fire, health, and sign rules before opening. This matters for storefronts, home businesses, food businesses, salons, studios, contractors, signs, and changes of use.
- Check industry licensing. Construction, home improvement contracting, alcohol, food, health care, childcare, real estate, cosmetology, massage, cannabis, transportation, and many other fields can have extra state or local approvals.
Practical order: Do not sign a lease, buy equipment, or advertise an opening date until you have checked zoning and permits for the exact address. In Massachusetts, city and town rules can decide whether your planned use is allowed at that location.
Federal, state, county, and city layers are different
Business licensing in Massachusetts is layered. One approval does not usually replace another.
| Layer | What it may cover | Massachusetts examples |
|---|---|---|
| Federal | Federal tax ID numbers and federally regulated activities. | IRS EIN, federal permits for certain industries, federal tax accounts, and federal rules for activities regulated by agencies such as ATF, FDA, USDA, FAA, FCC, or DOT. |
| State | Entity registration, state tax accounts, unemployment insurance, workers’ compensation, professional licenses, and state-regulated industries. | Secretary of the Commonwealth filings, MassTaxConnect, Department of Unemployment Assistance registration, Division of Occupational Licensure, Department of Public Health, ABCC, Cannabis Control Commission, and OCABR Home Improvement Contractor registration. |
| County | Massachusetts county government is usually not the main place for basic small-business licensing. | For most small businesses, start with the state and your city or town. County-level records or regional issues may still matter in special situations, but Massachusetts DBA and zoning checks are usually city or town matters. |
| City or town | Business certificates, zoning, building permits, certificates of occupancy or inspection, health permits, fire permits, signs, local alcohol steps, entertainment, vending, and other local approvals. | Boston, Cambridge, Worcester, Springfield, Lowell, and other municipalities each have their own clerk, zoning, health, inspectional services, and licensing process. |
| Private platform or marketplace | Rules from Amazon, Etsy, Shopify, delivery apps, payment processors, landlords, insurers, lenders, or marketplaces. | These are not government licenses, but they may ask for a tax registration certificate, EIN, local permit, insurance proof, or business documents. |
Do not mix the layers. An LLC is not a sales tax registration. A business certificate is not zoning approval. A MassTaxConnect account is not a city permit. A marketplace account is not government permission to operate.
State registrations and tax accounts
Entity filing with the Secretary of the Commonwealth
If you form a Massachusetts LLC or corporation, or register an out-of-state entity to do business in Massachusetts, you will likely work with the Secretary of the Commonwealth, Corporations Division.
Mass.gov says sole proprietors and general partnerships can usually skip the Secretary of the Commonwealth entity filing step, but they may still need a local business certificate, tax registration, local permits, or industry licenses.
For an LLC, Mass.gov says you file a Certificate of Organization with the Secretary of the Commonwealth. The official LLC page listed a $500 filing fee when checked. Fees can change, so confirm on the official filing page before paying.
Massachusetts LLCs also have ongoing annual-report duties. The Secretary’s LLC information page says every LLC must file an annual report with the Corporations Division on or before the anniversary date of its original certificate of organization.
Business certificate, DBA, trade name, fictitious name, or assumed name
Massachusetts uses the term business certificate for many DBA situations. Mass.gov explains that this document is sometimes called a DBA, trade name, fictitious name, or assumed name.
You generally file it with the city or town where the business is located if your business operates under a name different from its legal name.
Example: If Maria Lopez runs a sole proprietorship under “Lopez Home Cleaning,” that may be a business certificate issue in the city or town where the business is located. If an LLC named “Bay State Services LLC” operates publicly as “North Shore Window Pros,” it should check whether a business certificate is needed for that DBA name.
Name warning: A local business certificate does not give the same protection as a corporation, LLC, trademark, domain name, or brand clearance search. It mainly creates a public local record.
MassTaxConnect and Massachusetts Department of Revenue accounts
Massachusetts businesses use MassTaxConnect to register, file, and pay many business taxes with the Department of Revenue.
You may need MassTaxConnect if you sell taxable goods, sell taxable services, collect meals tax, collect room occupancy excise, have employees and withholding tax, owe corporate excise, or have another Massachusetts business tax duty.
Massachusetts sales and use tax is generally 6.25% on taxable sales of tangible personal property and certain services. DOR’s sales and use tax guide explains that after registration, a business receives a Sales and Use Tax Registration Certificate, Form ST-1, for each business location, and the certificate must be displayed where customers can see it.
Employer registrations
If you have employees in Massachusetts, you may have several separate duties. Do not treat one employer account as covering all employer rules.
| Employer item | Agency | What to check |
|---|---|---|
| Federal EIN | IRS | Many entities and employers need an EIN. Apply directly through the IRS, not through look-alike paid sites unless you choose to use a third party. |
| Massachusetts withholding tax | Massachusetts Department of Revenue | Register through MassTaxConnect if you must withhold Massachusetts income tax from wages. |
| Unemployment insurance | Department of Unemployment Assistance | DUA says employers who pay wages for work done in Massachusetts must register with DUA. |
| New hire reporting | Massachusetts Department of Revenue Child Support Services | Mass.gov says employers must report newly hired employees and independent contractors within 14 days of their first day of work. |
| Workers’ compensation insurance | Department of Industrial Accidents and insurance carriers | Mass.gov says all employers operating in Massachusetts must carry workers’ compensation insurance for employees, regardless of the number of employees or hours worked, with limited exceptions. |
Keep records: Save your EIN letter, Secretary filing receipt, MassTaxConnect confirmation, DUA registration, insurance proof, local business certificate, and permits in one folder. Local agencies may ask for proof before issuing or renewing permits.
City and town rules may decide whether you can open
Massachusetts is very local for many small-business steps. The city or town may handle the business certificate, zoning review, certificate of occupancy, building permits, sign permits, fire permits, health permits, and some local licensing.
Business certificates are local
Mass.gov says each city and town has its own process for filing a business certificate, usually through the clerk’s office. That means the form, fee, application method, notarization rules, renewal process, and supporting documents can vary by municipality.
Boston, for example, says business certificates are handled by the City Clerk’s Office and must be renewed every four years. Boston also says applicants cannot use a virtual address or post office box as the business location.
Worcester says business certificates are filed with the City Clerk for people or corporations doing business in Worcester under a company name. Springfield says its business certificate is valid for four years from filing and renewable after that. Lowell accepts business certificate filings through its City Clerk’s Office.
Zoning and occupancy come before opening
Before you open a storefront, studio, office, food space, salon, warehouse, or home-based business, check whether your planned use is allowed at the address.
Mass.gov’s zoning law page explains that Massachusetts cities and towns have authority under zoning law to regulate the use of land, buildings, and structures. Boston’s permitting page says the property’s certificate of occupancy shows the legal use on record for that property.
If your planned use does not match the property’s current legal use, you may need a zoning review, building permit, change of use, occupancy document, special permit, variance, or local board approval. Do not assume the landlord’s lease means the city or town will allow the use.
Health, food, fire, and building permits are often local
Restaurants, bakeries, food trucks, caterers, food processors, vending machines, mobile vendors, salons, body art businesses, gyms, childcare spaces, and event spaces may need local health, fire, building, or inspection approvals.
Massachusetts also has state-level food and health rules. The Department of Public Health Division of Food Protection covers many food safety topics and state-regulated food permits, while many retail food permits are handled through local boards of health.
Industry licenses and permits can matter more than the basic registration
Many Massachusetts businesses do not need a license because they are a business. They need a license because of what they do.
| Business type | Possible Massachusetts license or permit layer | Where to start |
|---|---|---|
| Electricians, plumbers, gas fitters, sheet metal, refrigeration, construction supervisors | State trade or public safety licenses, plus local building permits when work requires them. | Mass.gov building and trades licenses |
| Home improvement contractors | Home Improvement Contractor registration may be required for contractors, subcontractors, partnerships, or corporations that solicit, bid on, or perform work on existing owner-occupied residential property with one to four units. | Home Improvement Contractor registration |
| Restaurants, food trucks, food processors, bottled water, seafood, vending, meat or poultry processing | Local health permits and/or state Department of Public Health Division of Food Protection permits, depending on the activity. | Mass.gov food safety |
| Alcohol sales, manufacturing, storage, transportation, or service | Local licensing authority steps and/or Alcoholic Beverages Control Commission licenses or permits. ABCC says retail transactions must first be submitted to the municipality where the licensee will operate. | Apply for an ABCC license |
| Cannabis businesses | State cannabis licensing, local host community and zoning issues, and changing state rules. | Cannabis Control Commission applicants and licensees |
| Real estate, cosmetology, barbering, massage, architecture, engineering, home inspection, accounting, veterinary medicine | Professional licensing through Massachusetts boards and online license portals. | Mass.gov professional licenses and permits |
| Short-term rentals and lodging | Room occupancy excise registration and possible city or town registration, licensing, safety, zoning, or inspection rules. | Massachusetts room occupancy excise tax |
Regulated business warning: If your business involves food, alcohol, cannabis, construction, childcare, health care, transportation, personal services, or public assembly, check the state agency and the local city or town before you start taking customers.
Home-based businesses still need local checks
A home-based business in Massachusetts may still need a business certificate, zoning approval, home occupation registration, tax registration, or industry permit.
Local rules may limit customer visits, employees, signs, deliveries, outdoor storage, noise, parking, hazardous materials, food preparation, and changes to the residential character of the property.
Lowell, for example, has a home occupation page and says the zoning ordinance allows some home occupations to be registered with Development Services and the City Clerk. Bedford describes home occupation limits intended to keep the business incidental to the residential use and protect neighborhood character.
- Check whether your city or town allows your business type at your home address.
- Ask whether you need a home occupation permit or registration.
- Ask whether customer visits, employees, parking, deliveries, or signs are allowed.
- Check landlord, condo, HOA, or lease restrictions if you do not own the property.
- Check food, childcare, salon, health, chemical, or contractor rules if your activity is regulated.
Massachusetts city links
Use the city or town where the business is physically located. For mobile, online, home-based, or multi-city businesses, ask the city or town clerk and zoning office how they apply local rules.

Common Massachusetts licensing mistakes
- Calling everything a business license. Massachusetts may use different terms, including business certificate, Certificate of Organization, MassTaxConnect registration, Sales and Use Tax Registration Certificate, home occupation permit, health permit, Certificate of Occupancy, or professional license.
- Thinking an LLC replaces local approval. A Secretary of the Commonwealth filing creates or registers the legal entity. It does not approve the location, DBA name, taxes, food handling, building use, signs, or professional work.
- Skipping the city or town clerk. Massachusetts business certificates are local. The city or town process can affect your name, renewal, notarization, and supporting documents.
- Signing a lease before checking zoning. A lease does not prove the city or town allows the planned use at that address.
- Using a mailbox or virtual address without checking local rules. Boston says a virtual address or post office box cannot be used for a business location on its business certificate application.
- Not registering for sales tax before selling taxable items. If your business must collect Massachusetts sales and use tax, register with DOR and keep proper records.
- Missing employer steps. Employers may need federal, DOR, DUA, new hire, and workers’ compensation steps.
- Assuming an online business has no local rules. A home-based or online business can still trigger local DBA, zoning, tax, and industry rules.
- Starting regulated work without a state license. Check Massachusetts licensing boards before doing construction, home improvement, health, food, alcohol, cannabis, real estate, personal care, or other regulated work.
What to ask when you contact the agency
Before calling or emailing, have your business details ready. Include the business name, legal owner name, structure, city or town, address or general location, whether it is home-based or storefront, whether you sell products, whether you will have employees, and what services you provide.

FAQ
Do I need a statewide Massachusetts business license?
Massachusetts does not point every business to one single statewide general business-license application. Many businesses instead need a mix of entity filing, a city or town business certificate, MassTaxConnect tax registration, local zoning or occupancy approval, and activity-specific licenses.
Is a Massachusetts DBA filed with the state?
No. Massachusetts generally calls this a business certificate or DBA, and it is filed with the city or town where the business is located when the business operates under a name different from its legal name.
Is a business certificate the same as a business license?
No. Mass.gov says the business certificate is not a business license. It creates a public record of the business owner’s name and address, but it does not replace zoning, tax registration, health permits, professional licensing, or other approvals.
Do I need MassTaxConnect?
You may need MassTaxConnect if your business must register, file, or pay Massachusetts taxes, such as sales and use tax, meals tax, withholding tax, room occupancy excise, or other business taxes. Confirm your tax type with the Department of Revenue.
Do online businesses need local approvals in Massachusetts?
They may. An online business can still need a city or town business certificate, home occupation or zoning approval, sales and use tax registration, and industry permits depending on the name used, location, products, and services.
What if I have employees in Massachusetts?
Employers may need an EIN, Massachusetts withholding registration, Department of Unemployment Assistance registration, new hire reporting, and workers’ compensation insurance. Confirm details with the IRS, Massachusetts DOR, DUA, and DIA.
Does forming an LLC replace a local business certificate?
No. Forming an LLC with the Secretary of the Commonwealth creates or registers the legal entity. A city or town business certificate may still be needed if the business uses a different public name or if the local clerk requires it for your situation.
Where should I start?
Start with your legal structure and exact business location. Then check the Secretary of the Commonwealth, MassTaxConnect, your city or town clerk, zoning or building office, and any state licensing board that covers your industry.
