Janitorial business licensing — Massachusetts

Last reviewed: June 2, 2026  |  Primary sources: Massachusetts Secretary of State; MA DOR; MA DIA; SBA.gov

Massachusetts presents the highest labor law compliance burden of any state in this survey for commercial cleaning businesses. Three statutes combine to create a uniquely demanding environment: M.G.L. c. 149 §148B — the strictest independent contractor ABC test in the United States; the Massachusetts Wage Act (M.G.L. c. 149 §148), which mandates treble damages and attorneys' fees for all wage violations with no good-faith defense; and the Earned Sick Time Act (M.G.L. c. 149 §148C). A commercial cleaning operator in Massachusetts who misclassifies cleaners as 1099 contractors, fails to pay wages on time, or improperly handles sick time accrual faces mandatory treble damages — not just back pay. The Massachusetts Supreme Judicial Court confirmed in 2022 that treble damages apply even where the employer voluntarily corrects the violation before litigation.

Massachusetts does not require a statewide specialty license for commercial cleaning or janitorial services. Entity formation is handled by the Massachusetts Secretary of State, Corporations Division. LLC Certificate of Organization: $500; annual report: $500. Corporations: $275 formation; $125 annual. All employers must register with the Massachusetts Department of Revenue (MDOR) for withholding, unemployment, and — if applicable — sales tax accounts. Business registration and tax account setup are available through mass.gov/dor. MDOR contact: 100 Cambridge Street, Boston, MA 02114; (617) 887-6367.

Massachusetts Independent Contractor Law: M.G.L. c. 149 §148B

Massachusetts's Independent Contractor Law, codified at M.G.L. c. 149 §148B, is widely recognized as the most restrictive independent contractor statute in the United States. It presumes every service provider to be an employee unless all three prongs of a strict ABC test are satisfied:

• Prong A: The individual is free from control and direction in connection with the performance of service, both under the contract and in fact
• Prong B: The service is performed outside the usual course of the business of the employer
• Prong C: The individual is customarily engaged in an independently established trade, occupation, profession, or business of the same nature as that involved

Prong B is the fatal provision for cleaning companies. Because cleaning is the core business of a BSC, any cleaner performing cleaning work for a BSC will almost never satisfy Prong B — the service is squarely within the usual course of the cleaning company's business. This effectively bars the use of 1099 independent contractors as cleaning workers in Massachusetts unless the BSC can document that the independent operator truly runs their own separate cleaning company, uses their own equipment and scheduling, has multiple other clients, and has a genuine standalone business.

Violations of §148B expose the employer to the full penalties of the Wage Act: treble damages on all unpaid wages, all unpaid benefits (including employer-side WC premiums), full attorneys' fees, and criminal liability for individuals who manage the corporation. The Massachusetts Attorney General has prioritized enforcement against cleaning industry employers that misclassify workers. BSCs should convert all regular cleaning workers to W-2 status immediately and structure any legitimate subcontracting relationships through verified, independently licensed cleaning sub-companies.

Massachusetts Wage Act: Treble Damages and Attorneys' Fees

The Massachusetts Wage Act (M.G.L. c. 149 §148 and §150) requires employers to pay all earned wages on the established regular payday, with no exceptions for financial hardship or administrative error. Under §150, any employee who prevails on a Wage Act claim shall be awarded treble damages as liquidated damages for any lost wages and other benefits, plus costs and reasonable attorneys' fees. This mandatory treble damages provision applies to:

• Late payment of wages (even a few days late)
• Failure to pay earned overtime
• Improper wage deductions
• Failure to include all wage components in the regular paycheck
• Failure to pay earned PTO on termination (if the employer's policy provides that PTO vests)

There is no good-faith defense under Massachusetts law. A 2022 SJC ruling held that treble damages apply even if the employer discovers and corrects a violation voluntarily before any litigation. For cleaning companies — where split-shift schedules, tip-based incentive pay structures, and last-minute schedule changes are common — maintaining perfect payroll compliance is essential. Massachusetts payroll audits by the AG's office specifically target janitorial companies because of documented wage theft patterns in the industry.

Earned Sick Time Act: M.G.L. c. 149 §148C

The Massachusetts Earned Sick Time Act (M.G.L. c. 149 §148C) requires employers to provide paid sick leave to employees. Key parameters for cleaning companies:

• Accrual rate: 1 hour per 30 hours worked
• Maximum per year: 40 hours (employers with 11+ employees must provide paid sick time; employers with 10 or fewer may provide unpaid sick time)
• Employers with 11 or more employees must provide paid sick leave; smaller employers provide unpaid but job-protected leave
• Permitted uses: the employee's own illness or preventive care; care for family members; needs related to domestic violence
• Documentation: employers may request documentation only after 3 consecutive missed days
• Retaliation for using earned sick time is unlawful and subject to treble damages under the Wage Act cross-reference in §148C(l)

For a mid-size BSC with 50 cleaning workers averaging 35 hours/week, annual sick time accrual liability is approximately 2,000+ hours of paid leave. Companies that deny earned sick time, dock pay for sick day use, or fail to track and provide accurate sick time balances face compounded liability: the unpaid sick time plus treble damages plus attorneys' fees.

Workers' Compensation: First-Employee Threshold

Massachusetts requires workers' compensation coverage for employers with one or more employees under M.G.L. c. 152. There is no employee count threshold — coverage is mandatory from the moment a BSC hires its first W-2 worker. Massachusetts uses NCCI classification codes for most industries. However, Massachusetts maintains its own workers' compensation rating bureau: the Workers' Compensation Rating and Inspection Bureau of Massachusetts (WCRIBMA). Commercial cleaning is classified under NCCI Class Code 9014 in Massachusetts.

Massachusetts is not a monopolistic state; WC coverage is available through private carriers licensed by the Massachusetts Division of Insurance. The MA WC system is known for being one of the higher-cost states for cleaning industry employers. WCRIBMA contact: 101 Arch Street, Boston, MA 02110; (617) 439-9030; wcribma.org. Massachusetts Industrial Accidents Board handles WC claims disputes: 600 Washington Street, Boston, MA 02111; (617) 727-4900.

Sales Tax: Cleaning Services Are Not Taxable

Massachusetts does not impose sales tax on commercial cleaning or janitorial services. The Massachusetts sales tax (6.25%) applies to tangible personal property and a narrow set of services under M.G.L. c. 64H. Services are not taxable unless specifically enumerated, and cleaning services are not in the enumeration. BSCs should not collect or remit Massachusetts sales tax on cleaning service invoices.

However, if a BSC sells cleaning supplies, equipment, or products directly to customers (separate from the service), those tangible goods are subject to the 6.25% sales tax. BSCs that purchase cleaning supplies for their own use in providing services (i.e., the supplies are consumed in performing the service) generally owe Massachusetts use tax on those supplies unless they are purchased from a vendor who collected MA sales tax.

Local Business Licensing in Boston and Other Cities

Massachusetts does not have a statewide business license. However, individual cities and towns may require local business registration, DBA filings, or licenses:

• Boston: All businesses operating in Boston must register with the Boston Office of Planning and Development. A business certificate (DBA) must be filed with the City Clerk for $65 every four years. Some commercial cleaning operations in Boston-owned buildings may require certification under the Boston Residency Jobs Policy.
• Cambridge: Business certificate filing with City Clerk; fee ~$65 every four years
• Worcester, Springfield: Local DBA/business certificate with City Clerk; typical fee $20–$50

Massachusetts cities with large commercial cleaning markets sometimes require vendors on city contracts to hold Wage Theft Prevention certifications or submit payroll documentation demonstrating Wage Act compliance. The City of Boston's Living Wage Ordinance (effective for city-funded service contracts over $100,000) mandates a living wage floor that exceeds the state minimum wage.

State Unemployment Insurance

Massachusetts UI is administered by the Massachusetts Department of Unemployment Assistance (DUA). Employers register at uionline.detma.org. New employer rate: 2.42% on the first $15,000 of wages per employee (2024 wage base). Experienced employers are rated on a 5-year schedule ranging from 0.94% to 14.37%. Massachusetts also charges a UI Solvency Assessment (currently 0.97%) and a Workforce Training Fund contribution (0.056%), making the effective new employer rate approximately 3.4% in 2024. Massachusetts DUA conducts joint audits with the AG's office specifically targeting cleaning industry employers for IC misclassification.

PFAS and Chemical Regulation

Massachusetts does not yet have a standalone PFAS restriction law specific to cleaning products (unlike Minnesota, which bans certain PFAS in jan-san products), but the Massachusetts Department of Environmental Protection (MassDEP) has established Maximum Contaminant Levels (MCLs) for PFAS in drinking water (6 ppt combined), and has guidance on PFAS in waste disposal. Cleaning companies using PFAS-containing products in Massachusetts should monitor MassDEP's PFAS regulatory updates, as further restrictions on PFAS in cleaning and maintenance products are under active consideration by the Massachusetts Legislature as of 2026.
