3 stopsMassachusetts Master Plumber License
A master plumber license from the Division of Occupational Licensure's Board of State Examiners of Plumbers and Gas Fitters is required to contract for plumbing work in Massachusetts. Applications must be submitted online through the eLIPSE platform (mailed applications are returned) and require a Statement of Experience and Education Verification Form carrying your journeyman plumber license number and signed by a school official and your plumbing instructor, a notarized CORI acknowledgement, and a 2x2 passport-style photo; you then sit the PSI exam. To operate as a plumbing company you also need a plumbing business license, which requires organizing documents filed with the Secretary of the Commonwealth naming plumbing as the business purpose and listing the master plumber of record as an officer, manager or partner, plus a CORI check on each such master plumber.

Liability Insurance for Massachusetts Plumbing Contractors
Massachusetts sets no statutory minimum coverage amount for plumbers, but liability insurance is effectively required at permit time: when applying for a plumbing or gas permit, a licensed plumber or gas fitter must sign, under the penalties of perjury, that they carry liability insurance — or present a waiver of insurance signed by the homeowner. Only a master or journeyman plumber licensed by the Board of State Examiners of Plumbers and Gas Fitters, with a permit from the local plumbing inspector, may do plumbing work. A master plumber may work as an individual, a firm, or a corporation, must keep a regular place of business with the current license displayed, and may employ journeymen and apprentices. Higher coverage limits are commonly imposed by general contractors, landlords, and commercial clients through contract rather than by the state.

Massachusetts Business Entity Registration (LLC or Corporation)
Entity filings go to the Corporations Division of the Secretary of the Commonwealth. Which filing you make depends on the structure you chose: an LLC files a Certificate of Organization, a corporation files Articles of Organization. Sole proprietors and general partnerships do not file with the Secretary at all — they only file a business certificate (DBA) with their city or town clerk, and then only if they trade under a name other than the owner's legal name. Check name availability in the Secretary's Business Entity Search first. After the entity is approved you still need to decide whether a DBA is required, get an EIN from the IRS, and register with MassTaxConnect if you will collect or pay state tax. Every Massachusetts employer must also carry workers' compensation insurance, including where you are an employee of your own company. Businesses formed in the United States are exempt from federal beneficial ownership (BOI) reporting; those formed abroad are not. Entity registration is separate from the individual plumber's licence and from the master plumber requirement for operating a plumbing business.
Official government source$500 to file an LLC Certificate of Organization. A for-profit or professional corporation files Articles of Organization for $275 covering up to 275,000 authorized shares, plus $100 for each additional 100,000 shares; a non-profit corporation is $35 and a foreign entity is $400. Sole proprietors and general partnerships pay the Secretary nothing — only the local business certificate fee, which in Boston is $65. Budget for the annual report too: $500 every year for an LLC, and $125 for a for-profit corporation ($100 if filed electronically).You can file online, by fax, by mail, or in person, and online is the fastest route. The Corporations Division does not publish a guaranteed processing time, so confirm current turnaround when you file. The entity does not legally exist until the Secretary approves the filing, so do not sign a lease or open accounts in the entity's name before you have the approved certificate back.

City of Boston / Suffolk County
2 stopsCity of Boston Business Certificate (DBA) for a Plumbing Business
Massachusetts General Laws chapter 110, section 5 requires anyone conducting business under a title other than their real legal name to file a certificate with the clerk of every city or town where the business has an office. In Boston that is the City Clerk's Office. This is a public record of who owns the business, not a business license, and it does not replace or substitute for any trade or health license. The trigger is the name, not the entity type: a sole proprietor, partnership, LLC, or corporation all must file if the operating name differs from the owner's legal name or the name on record with the Secretary of the Commonwealth. Your signature must be executed under oath, so the form has to be notarized (the Clerk's Office will notarize it if you bring valid photo ID). You must supply a signed lease with start and end dates, or a notarized letter from your landlord; a virtual address or P.O. box is not accepted. The certificate is in force for four years and must be renewed every four years or it lapses. Operating without one is punishable by a fine of up to $300 for each month the violation continues. A plumbing company organized as an LLC or corporation is not exempt: it files a Boston certificate whenever it trades under a name other than its registered entity name.

Boston Plumbing Permits and Massachusetts Plumbing Corporation Certificate
Boston has no separate ISD plumber registration. What governs is state licensure: the Board of State Examiners of Plumbers and Gas Fitters, under the Division of Occupational Licensure, licenses journeyman and master plumbers and gas fitters, registers apprentices, and issues corporate and partnership certificates to plumbing and gas businesses. A plumbing company organized as a corporation or partnership needs that certificate, and the work must be done by licensed plumbers. Boston's part is per job: the Inspectional Services Department requires a plumbing permit for each job, pulled by the licensed plumber.
