How to Start a Business in Massachusetts (2026)

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

Massachusetts has no single statewide general business license. You start a business by forming your entity (an LLC files a Certificate of Organization with the Secretary of the Commonwealth) and registering for taxes with the Massachusetts Department of Revenue on MassTaxConnect, where sales and use tax registration is free and the sales tax rate is 6.25%.

Starting a Business in Massachusetts: The Core Steps

Launching a business in Massachusetts involves four building blocks: choosing a legal structure, forming the entity with the Secretary of the Commonwealth, registering for state taxes with the Department of Revenue (DOR), and confirming any local or professional licenses. There is no one "Massachusetts business license" you buy from the state. Instead, your obligations depend on your entity type, what you sell, whether you have employees, and where you operate.

Most owners choose between operating as a sole proprietorship, a general partnership, a limited liability company (LLC), or a corporation. A sole proprietorship needs no state formation filing, but it gives you no liability shield. An LLC or a corporation is a separate legal entity that limits owners' personal liability and is created by a filing with the Corporations Division. This guide focuses on the LLC path because it is the most common choice for new small businesses, while noting where sole proprietors and corporations differ. For the tradeoff between pass-through and corporate tax treatment, see S-corp vs LLC.

Form Your Entity With the Secretary of the Commonwealth

A Massachusetts LLC is created by filing a Certificate of Organization with the Secretary of the Commonwealth, Corporations Division, under the Massachusetts Limited Liability Company Act, General Laws Chapter 156C. The certificate lists the LLC's name, the office address, the resident agent, the general character of the business, and the authorized signatories. The name must be distinguishable from other entities on record and include an LLC designator such as "LLC" or "Limited Liability Company." You can file online through the Corporations Division or by mail. Confirm the current filing fee on the Corporations Division fee schedule before you file, and budget for the annual report the state requires each year.

Every Massachusetts LLC must appoint and continuously maintain a resident agent with a Massachusetts address to receive service of process and official notices. You may act as your own agent, name a manager, or hire a commercial service. Adopt an operating agreement as well: Massachusetts does not file it, but it governs ownership percentages, management, and profit distribution among members. If you plan to operate under a name other than your legal entity name, you generally file a business certificate (a DBA) with the city or town clerk where you do business, not with the state.

Get an EIN and Register for Taxes on MassTaxConnect

After your entity exists, apply for a federal Employer Identification Number (EIN). The EIN is issued free by the IRS and is used to open a bank account, hire employees, and register for state tax accounts. By default the IRS treats a single-member LLC as a disregarded entity and a multi-member LLC as a partnership; either can elect S-corporation or corporate treatment by filing the right IRS form. An LLC with no employees and one owner who is not otherwise required to have an EIN may sometimes use the owner's Social Security number or ITIN, but most businesses need an EIN.

Next, register with the Massachusetts Department of Revenue through MassTaxConnect, the state's online tax portal. Registration sets up the accounts your business needs: employer withholding if you pay wages, corporate excise if you are taxed as a corporation, and sales and use tax if you sell taxable goods or services. The Massachusetts sales and use tax rate is 6.25%, and vendor registration is free. You must register as a vendor and begin collecting tax before your first taxable sale. Massachusetts also imposes a personal income tax that flows through to LLC members on their individual returns, so plan for quarterly estimated payments. See business tax basics for how pass-through income is reported.

Local and Professional Licenses in Massachusetts

Because Massachusetts issues no single statewide general business license, licensing is layered. First, check with the city or town where you operate: many municipalities require local business permits, zoning or use approvals, health permits for food establishments, and sign permits. Second, check whether your profession or occupation is regulated at the state level. Massachusetts licenses dozens of trades and professions, from electricians and plumbers to cosmetologists, contractors, real estate agents, and health professionals, through the Division of Occupational Licensure and other boards. A regulated professional generally cannot operate lawfully without the applicable state license, regardless of whether the LLC is properly formed.

The federal business license layer applies only to federally regulated activities such as alcohol, firearms, or commercial transportation. For most Main Street businesses, the practical checklist is: form the entity, register for DOR taxes, obtain any local permit, and secure any professional license. Use the U.S. Small Business Administration's licensing overview and the DOR's registration guidance to map your specific requirements, and keep documentation of each approval with your company records.

A few Massachusetts specifics are worth flagging. If you sell prepared food, you generally need a local board of health permit in addition to your DOR meals tax registration. If you serve alcohol, you apply through the local licensing authority and the Alcoholic Beverages Control Commission. Retailers that sell cigarettes or tobacco need a separate state license. And if you hire employees, you must register for unemployment insurance with the Department of Unemployment Assistance and carry workers' compensation coverage. Because requirements vary by city, town, and industry, the safest approach is to call your municipal clerk and search the relevant state board before you open. Building this checklist early prevents the most common startup delays, which come from missing a local permit rather than a state filing.

Step-by-Step Startup Checklist

The steps below tie the sections above into the order most Massachusetts founders follow. Each maps to a requirement of state law or a federal tax rule.

1. Choose your structure and name. Decide between sole proprietorship, partnership, LLC, or corporation, and confirm your name is available and distinguishable in the Corporations Division records. Consider whether the name is free of a conflicting federal trademark.
2. Form the entity. File the Certificate of Organization with the Secretary of the Commonwealth and appoint a Massachusetts resident agent. The LLC exists once the Corporations Division accepts the filing.
3. Get a free EIN. Apply directly with the IRS. Never pay a third party for the number itself; the IRS issues it at no cost.
4. Register for taxes. Set up your accounts on MassTaxConnect for withholding and, if applicable, sales and use tax at 6.25%.
5. Handle licenses and insurance. Obtain local permits, any state professional license, and required insurance such as workers' compensation if you have employees.

When you eventually wind down, follow the state's dissolution steps so tax and reporting obligations stop cleanly. Keeping your resident agent current, filing the annual report on time, and staying registered with the DOR are the three habits that keep a Massachusetts entity in good standing year after year.
