1. Massachusetts Sales Tax Vendor Registration

   Businesses selling taxable goods or meals in Massachusetts must register as a sales tax vendor with the Department of Revenue through MassTaxConnect. There is no 'ST-1' form in Massachusetts — registration is done online, and the ST-4 form is a separate exempt purchase certificate. Registration requires your EIN (sole proprietors with no employees may register under a Social Security number), the business start date, and the legal and mailing addresses; entities other than sole proprietorships also list owners and officers with titles and Social Security numbers. Massachusetts taxes tangible personal property, not services, so a business selling only services generally has nothing to register for.

2. General Liability Insurance for a Massachusetts Pressure Washing Business (Client-Required, Not State-Required)

   Massachusetts does not license pressure washing and does not require the business to carry general liability insurance. The requirement comes from your customers: commercial clients and property managers routinely demand a certificate of insurance, often naming them as an additional insured, before letting a contractor on site, and the limits are set by that contract rather than by the Commonwealth. Commercial auto cover is a separate policy from general liability and is needed for company vehicles and trailers. If you have employees, workers' compensation is genuinely mandatory in Massachusetts and is not the same thing as liability insurance — the Department of Industrial Accidents makes that distinction explicitly. Two other issues bite this trade specifically: wash water discharge to a storm drain can trigger local stormwater rules, and work on pre-1978 painted surfaces can raise lead-safe practice requirements. Check any carrier is admitted in Massachusetts through the Division of Insurance.

   There is no state fee — the Commonwealth requires nothing here. Premiums are set by the carrier and vary with the limits your clients demand, your payroll and revenue, and whether roof or height work is included, so price against the specific limits in the contracts you are bidding.·A broker can generally bind general liability cover quickly once the application is complete, and issue job-specific certificates on request. Get the client's written insurance requirements before you buy so you are not re-writing the policy to add an endorsement mid-job.

1. Boston Business Certificate (if operating under a trade name)

   Boston does not issue a general business license from Inspectional Services, and there is no citywide gross-receipts license fee. What the City requires is a Business Certificate from the City Clerk's Office if you run a pressure washing business under a trade name rather than your own legal name. The certificate must be renewed every four years from the date you registered, and a late fee applies if you miss the renewal (M.G.L. c. 110, s. 5).

2. Boston Wash Water Discharge Rules (BWSC and MassDEP)

   There is no Suffolk County environmental health department — in Boston, drainage and sewer rules come from the Boston Water and Sewer Commission and wastewater rules from MassDEP. BWSC's Sewer Regulations prohibit discharging anything not composed entirely of stormwater into a storm drain, and separately prohibit dumping soap, detergent, oil, grease, or solvents into any catch basin. Building washdown water is allowed to reach a storm drain only if it contains no detergents, so pressure washing with any cleaning agent must be captured rather than left to run to the curb. MassDEP prohibits discharging industrial wastewater to a septic system, or dumping it on the ground without a groundwater discharge permit. In practice: contain your runoff, recover it with a vacuum or pump, and dispose of it through a sanitary sewer connection or a licensed hauler after checking your local sewer authority's requirements.

   Official government source

   No permit fee applies to a compliant operation that keeps wash water out of the drainage system; your costs are containment and recovery equipment plus disposal. Anyone BWSC finds responsible for a discharge into a catch basin can be billed for cleaning it and assessed penalties.·Ongoing compliance — the rules apply from your first job, with no application or waiting period
