Employee or contractor? The Massachusetts independent contractor test

Key takeaways

• Massachusetts General Laws chapter 149, section 148B treats anyone who performs a service as an employee unless the business proves all three prongs of the independent contractor test.
• The three prongs are freedom from control and direction, work outside the usual course of the employer’s business, and an independently established trade of the same nature.
• Failing to withhold taxes, issuing a Form 1099 or signing a contractor agreement does not count toward the test, according to section 148B and the Attorney General’s Advisory 2008/1.
• The Attorney General can issue a civil citation of up to $25,000 per violation under chapter 149, section 27C, with lower caps of $15,000 and $7,500 for some first-time violators.
• A misclassified worker who wins a civil suit under chapter 149, section 150 is awarded triple damages for lost wages and benefits, plus litigation costs and reasonable attorneys’ fees.
• The Department of Unemployment Assistance and the Internal Revenue Service apply their own tests, so one worker can be a contractor for federal tax purposes and an employee under Massachusetts wage law.

The Massachusetts independent contractor law is a state statute, General Laws chapter 149, section 148B, that presumes a worker is an employee unless the business can prove a three-prong test. If you own or manage a small business in Boston, Cambridge, Somerville, Brookline or any other Massachusetts city or town, the same state rule applies to you. No city or town sets its own version.

This guide covers the three prongs, the Attorney General’s enforcement advisory, the penalties in the General Laws, worker lawsuits, and the separate tests used for unemployment insurance, workers’ compensation and federal taxes.

What is the Massachusetts independent contractor law?

The Massachusetts independent contractor law is General Laws chapter 149, section 148B, a state statute that decides who counts as an employee for the wage and hour laws in chapter 149 and the minimum wage and overtime law in chapter 151. Under the statute, an individual performing any service is considered an employee unless three conditions are met.

The Attorney General’s Fair Labor Division enforces the law. Its independent contractors page says most people who work or provide services in Massachusetts are employees, and that the employer is the one who must show the test is met. Misclassification is treating a worker as a contractor when the worker fails any part of the test.

What are the three prongs of the Massachusetts independent contractor test?

The three prongs of the Massachusetts independent contractor test are set out in section 148B(a), and a business must prove every one of them. The statute joins them with “and”, so failing a single prong makes the worker an employee.

1. Prong one: the individual is free from control and direction in connection with the performance of the service, both under the contract and in fact.
2. Prong two: the service is performed outside the usual course of the business of the employer.
3. Prong three: the individual is customarily engaged in an independently established trade, occupation, profession or business of the same nature as the service performed.

The Attorney General’s Advisory 2008/1 explains how the office reads each prong. On prong one, a contract that says the worker is unsupervised is not enough by itself; the worker has to be free of control in day-to-day fact.

How prong two works in the advisory’s examples

Prong two is where many small businesses fail, because it looks at what your business sells. Advisory 2008/1 gives these examples: a drywall company that classifies its drywall installers as contractors violates prong two, and so does a real estate appraisal company that classifies its appraisers as contractors. An accounting firm that hires a mover to relocate office furniture does not violate prong two, because moving furniture is incidental to accounting.

Does a 1099, a contract or an LLC make a worker a contractor in Massachusetts?

A 1099, a written contract or an LLC does not make a worker an independent contractor in Massachusetts. Section 148B(b) says the failure to withhold federal or state income taxes, or to pay unemployment contributions or workers’ compensation premiums, is not considered in deciding a worker’s status. Section 148B(c) says the same about a worker who buys workers’ compensation coverage as a sole proprietor or partnership.

Advisory 2008/1 adds that an employer’s belief that a worker should be a contractor is irrelevant. The Attorney General’s Office also states in the advisory that it will act against businesses that allow, request or contract with LLCs or S corporations created to get around the law. In those cases the office considers whether the contractor’s services are in fact available to other customers and whether the contractor’s company exists only because the hiring business required it.

What does the Attorney General look for when enforcing the independent contractor law?

The Attorney General looks for two things before treating a case as a violation of the independent contractor law, according to Advisory 2008/1. First, the business classified a worker as something other than an employee even though the worker fails at least one prong. Second, the business broke one of the laws listed in section 148B(d) while using that worker, such as the wage payment rules in chapter 149, minimum wage and overtime in chapter 151, or income tax withholding under chapter 62B.

The advisory lists these signs as strong indicators of misclassification that can lead to an investigation:

• Workers who do not appear in the business’s records.
• Workers paid off the books, in cash, or with no payment documents.
• Missing or insufficient workers’ compensation coverage.
• Workers who receive neither a 1099 nor a W-2 from any entity.
• A hiring business that supplies the equipment, tools and supplies, or requires workers to buy them from it.
• Alleged contractors who pay no income tax or unemployment contributions.

One limit matters here. The advisory says the law does not reach a business whose workers are all paid as W-2 employees, and that subcontracting work to another company that employs its own workers falls outside section 148B.

What are the penalties for misclassifying an employee in Massachusetts?

The penalties for misclassifying an employee in Massachusetts are set by General Laws chapter 149, section 27C, which section 148B(d) applies to misclassification. The Attorney General chooses between criminal prosecution and a written warning or civil citation. The table shows the maximums in the statute as published on November 13, 2026.

Type of case under section 27C	Maximum penalty
Willful violation, first offense	$25,000 fine, one year in jail, or both
Willful violation, later offense	$50,000 fine, two years in jail, or both
Violation without willful intent, first offense	$10,000 fine or six months in jail
Violation without willful intent, later offense	$25,000 fine, one year in jail, or both
Civil citation, per violation	$25,000
Civil citation, no prior conviction or citation	$15,000
Civil citation, no prior record and no specific intent found by the Attorney General	$7,500

A civil citation can also order restitution to the worker, and section 27C gives the business 21 days from the date of issuance to comply. An appeal goes to the Attorney General and the Division of Administrative Law Appeals within 10 days of receiving the citation.

Section 148B(d) makes the business entity liable along with the president and treasurer of a corporation and any officer or agent who manages it. Contractors on public construction face debarment too: a conviction for willfully violating section 148B bars a contractor from state and municipal public works for five years under section 27C(a)(3).

Can a worker sue a business over misclassification in Massachusetts?

A worker can sue a business over misclassification in Massachusetts under General Laws chapter 149, section 150. The worker first files a complaint with the Attorney General, then may bring a civil action 90 days later, or sooner if the Attorney General assents in writing. The suit must be filed within three years of the violation, and the statute pauses that clock while the complaint is with the Attorney General.

A worker who prevails is awarded triple damages for lost wages and other benefits, plus the costs of the litigation and reasonable attorneys’ fees.

Workers start the process through the Attorney General’s workplace complaint page, which lists misclassification as an independent contractor under the non-payment of wage category. The Fair Labor Hotline is (617) 727-3465, open Monday through Friday from 10 a.m. to 4 p.m.

Do unemployment insurance, workers’ compensation and the IRS use the same test?

Unemployment insurance, workers’ compensation and the IRS do not use the same test as section 148B, so a worker’s status has to be checked under each one.

• Unemployment insurance: the Department of Unemployment Assistance applies chapter 151A, section 2. Its second prong is looser, because the work can be outside the usual course of the business or outside all of the business’s places of business. The Department of Unemployment Assistance says 1099 status is not part of its test.
• Workers’ compensation: the Department of Industrial Accidents says on its independent contractors page that status is a question of fact with no simple rule, and that workers are presumed to be employees under section 148B.
• Federal taxes: the Internal Revenue Service weighs common-law factors in three categories (behavioral, financial and type of relationship), and no single factor decides the outcome. A business or worker can file Form SS-8 for an IRS determination, which the IRS says can take at least six months.
