Massachusetts HR Compliance Guide for Employers

Massachusetts combines some of the country's most protective wage laws with a recording consent statute that carries felony penalties, a non-compete framework unlike any other state, a state-run paid family and medical leave program, and an anti-discrimination law that kicks in at six employees. For HR onboarding, this is a state where compliance mistakes carry severe financial consequences and where assumptions borrowed from federal law or neighboring states frequently lead employers astray.

The Wage Act's mandatory treble damages are perhaps the most consequential single rule. Any violation, including a one-day delay on a final paycheck, triggers automatic three-times damages plus attorney fees. There is no good faith defense. The Massachusetts Supreme Judicial Court confirmed this in Reuter v. City of Methuen (2022).

This guide covers every major employment law requirement for Massachusetts employers as of 2026, with particular focus on the rules that apply to businesses with 5 to 50 employees.

What Makes Massachusetts Unique for Employers

Massachusetts has one of the most complex and employer-demanding compliance environments in the country. Several of its rules have no parallel in federal law or in most other states.

Seven compliance areas stand out as particularly distinctive for employers entering Massachusetts from other states:

The Wage Act treble damage rule is the first and most important. Under M.G.L. c. 149, §§ 148 and 150, any violation of wage payment requirements triggers mandatory damages of three times the unpaid wages plus attorney fees and costs. Corporate officers are personally liable. There is no defense based on good faith or honest mistake.

Massachusetts is an all-party consent state for audio recordings, and violation is a felony under M.G.L. c. 272, § 99, carrying penalties of up to $10,000 and five years in state prison. Employers cannot secretly record any call, meeting, or conversation. The standard is whether the recording is secret, not whether all parties consented.

The Massachusetts Noncompetition Agreement Act requires garden leave equal to 50% of the employee's highest annualized base salary over the prior two years, paid pro-rata throughout the restricted period. This is a unique requirement with almost no equivalent in other US states.

The PFML program is a state-run insurance system, not an employer-funded leave program. Employers and employees both contribute; employees receive benefits directly from the state. The 2026 maximum weekly benefit is $1,230.39.

Chapter 151B anti-discrimination law covers employers with six or more employees and 14 or more protected classes, well below the federal threshold of 15. Punitive damages are uncapped in Massachusetts Superior Court.

Any employer storing personal information of Massachusetts residents must maintain a Written Information Security Program under 201 CMR 17.00, regardless of where the employer is located or how many employees they have.

Sunday and holiday premium pay for retail workers was fully eliminated effective January 1, 2023. Many online resources still reference these premiums as current requirements. The voluntariness provisions that prevent retailers from requiring employees to work Sundays or holidays remain in effect.

Employment Law Foundations in Massachusetts

Massachusetts is an at-will employment state, but with a notably broad set of statutory and common law exceptions compared to most states.

At-will employment and its exceptions

An employee handbook can create contractual obligations under the implied contract doctrine, so clear at-will language is essential for Massachusetts employers. Massachusetts courts also recognize the public policy exception and the covenant of good faith and fair dealing in employment. Massachusetts is one of a small number of states that applies the covenant of good faith in employment contexts. Massachusetts is one of a small number of states that applies the covenant of good faith in employment contexts. Statutory anti-retaliation protections span the Wage Act, Chapter 151B, PFML, workers' compensation, and the whistleblower protection act at M.G.L. c. 149, § 185.

Massachusetts Commission Against Discrimination (Chapter 151B)

Chapter 151B applies to employers with six or more employees and covers race (including hair texture and protective hairstyles under the 2022 CROWN Act), color, religious creed, national origin, sex (including pregnancy, childbirth, lactation, and gender identity), sexual orientation, genetic information, ancestry, age (40 and older), disability, veteran and military status, and criminal record. Employees have 300 days from the last discriminatory act to file with the MCAD. After 90 days in the MCAD process, employees may remove the case to Superior Court. Massachusetts has no cap on compensatory or punitive damages in Superior Court, a significant distinction from federal Title VII's $50,000 to $300,000 caps.

Massachusetts Wage Act

The Wage Act at M.G.L. c. 149, §§ 148–150 is the strictest wage law in the country. Mandatory treble damages apply to every violation without exception. The statute of limitations is three years. Corporate officers with financial management authority are personally liable for violations. Employees may file a complaint with the Attorney General's office and then bring a private lawsuit after 90 days. The SJC's 2022 decision in Reuter v. City of Methuen confirmed that good faith belief that wages were not owed provides no defense.

Hiring and Onboarding Requirements

Massachusetts new hire paperwork involves more required documents at hire than most states, including multiple mandatory written notices and strict criminal history rules. A comprehensiveemployee onboarding checklist is essential for tracking all Massachusetts-specific requirements.

CORI and ban-the-box

Massachusetts prohibits asking about criminal records on the initial written job application under M.G.L. c. 151B, § 4(9½). At any stage of the process, employers may never ask about: arrests without conviction; first convictions for drunkenness, simple assault, speeding, minor traffic offenses, affray, or disturbance of the peace; misdemeanors more than three years old; sealed or expunged records; or juvenile records. Felony lookback is 10 years under Standard CORI Access; consumer reporting agencies are limited to 7 years under M.G.L. c. 93, § 52. Employers conducting five or more background checks per year must have a written CORI policy. An individualized assessment is required before any adverse action; the applicant must receive a copy of their CORI report before any adverse decision.

Pay transparency (effective October 29, 2025)

The Frances Perkins Workplace Equity Act signed July 31, 2024 requires employers with 25 or more employees to include a pay range in all job postings, including internal postings, external postings, third-party recruiter postings, and social media listings. Full guidance is available at mass.gov/info-details/pay-transparency-in-massachusetts. The range must represent what the employer reasonably and in good faith expects to pay. Pay ranges must also be provided upon request by applicants or current employees and at promotion or transfer. A first offense results in a warning; second offense: $500; third offense: $1,000. The AG enforces exclusively; there is no private right of action and these violations are not subject to Wage Act treble damages. Separate from the posting requirement, the EEO-1 data reporting obligation for employers with 100 or more employees took effect February 1, 2025.

Drug testing

Massachusetts has no comprehensive drug testing statute for private employers. Testing is governed by case law and the privacy statute at M.G.L. c. 214, § 1B. Pre-employment testing is permitted after a conditional offer if testing is required of all applicants for the same position. Random testing is prohibited for non-safety-sensitive positions. In Barbuto v. Advantage Sales and Marketing (2017), the Supreme Judicial Court held that employers may be required to reasonably accommodate registered medical marijuana patients for off-duty use, depending on the position and circumstances. Recreational marijuana users do not receive the same accommodation protection.

Wage and Hour Rules That Catch Employers Off Guard

Massachusetts wage and hour law contains several rules that differ significantly from federal FLSA and from most other states, with penalties more severe than anywhere else in the country.

Minimum wage and service rate

The Massachusetts minimum wage is $15.00 per hour under M.G.L. c. 151, § 1, reached on January 1, 2023 as the final step of the Grand Bargain phase-in. There are no scheduled increases and no CPI indexation. Any future increase requires a new law or ballot question. Agricultural workers have a separate rate of $8.00 per hour. The service or tipped rate is $6.75 per hour. The tip credit is $8.25, but the employer must make up any shortfall if tips plus the service rate do not equal the full $15.00 minimum wage. This top-up calculation must be made at the end of each shift, not at the end of the pay period. Employers and managers may not participate in tip pools under M.G.L. c. 149, § 152A. Service charges go only to wait staff, service employees, and service bartenders.

Overtime

Massachusetts requires 1.5 times the regular rate for hours over 40 per week under M.G.L. c. 151, § 1A. There is no daily overtime threshold. One Massachusetts-specific rule to note: commissions and certain bonuses are excluded from the regular rate calculation for overtime purposes under Massachusetts case law, unlike the federal FLSA approach. A broad list of employer categories are exempt from the overtime requirement, including hotels, restaurants, hospitals, gas stations, and seasonal businesses.

Mandatory meal breaks

Under M.G.L. c. 149, § 100, employers must provide a 30-minute meal break after 6 hours of work. The break may be unpaid only if the employee is completely relieved of duties and free to leave the premises. An employee may voluntarily waive the break. Criminal fines of $300 to $600 apply per violation. Requiring an employee to work through a break and then deducting the time from their pay violates the Wage Act, triggering mandatory treble damages.

Sunday and holiday premium pay: eliminated

The Grand Bargain phase-out of Sunday and holiday premium pay for retail workers completed on January 1, 2023. The premium rate phased from 1.5 times in 2018 down to 1.0 times over five steps. Many employers and HR resources still incorrectly state that Sunday premiums are required. They are not. However, the voluntariness provisions that prevent retailers from requiring employees to work on Sundays or holidays remain fully in effect. Retail workers cannot be disciplined, penalized, or terminated for refusing to work on a Sunday or holiday.

Final paycheck rules

When an employer discharges an employee, final wages are due on the day of discharge under § 148. When an employee quits, final wages are due on the next regular payday or the following Saturday, whichever comes first. Final wages include all earned but unpaid wages, accrued vacation time if your written policy provides for payout, and earned but unpaid commissions. Paying by direct deposit on the next business day after a termination is a violation. Any late or short payment triggers mandatory treble damages plus attorney fees. Corporate officers who have management responsibility for wage payment are personally liable.

Equal Pay Act and salary history ban

The Massachusetts Equal Pay Act at M.G.L. c. 149, § 105A took effect July 1, 2018. It prohibits pay discrimination based on gender for comparable work, defined as work requiring substantially similar skill, effort, and responsibility under similar working conditions. This is a broader standard than identical work. Six defenses are permitted: seniority, merit, production, sales, or revenue-based pay, geographic location differentials, education, training, or experience, and required travel. The salary history ban, also in § 105A, prohibits asking any applicant about prior salary before making an offer, and prohibits conditioning consideration on meeting a minimum prior salary level. Damages are two times unpaid wages plus attorney fees, with a three-year statute of limitations. An employer who conducts a good-faith self-evaluation of pay practices within the three years before a claim gains an affirmative defense.

Earned Sick Time: What Every Massachusetts Employer Must Know

Massachusetts Earned Sick Time under M.G.L. c. 149, § 148C applies to all employers regardless of size. The key distinction is whether the time is paid or unpaid, which depends on headcount.

All employees are counted for threshold purposes: full-time, part-time, temporary, and seasonal workers. Employers with 11 or more employees must provide paid sick time. Employers with fewer than 11 employees must provide unpaid sick time. Accrual begins on the first day of employment at a rate of one hour per 30 hours worked, up to a cap of 40 hours per year. Employees may begin using accrued time after 90 days of employment. Exempt employees are assumed to work 40 hours per week for accrual purposes.

Earned sick time may be used for the employee's own illness, injury, or medical condition; care for a child, spouse, parent, or parent of a spouse; routine medical or dental appointments; effects of domestic violence; and, since November 2024, pregnancy loss, failed assisted reproduction, failed adoption, and failed surrogacy.

Paid Family and Medical Leave: Massachusetts's Signature Program

Massachusetts PFML at M.G.L. c. 175M is a state-run insurance program administered by the Department of Family and Medical Leave (DFML). It is not an employer-funded leave benefit; employees receive benefits directly from the state. More information is at mass.gov/dfml.

Leave duration

PFML provides up to 20 weeks per benefit year for medical leave covering the employee's own serious health condition, and up to 12 weeks per benefit year for family leave covering bonding after birth or adoption, caring for a family member's serious health condition, or military qualifying exigency. Military caregiver leave extends to 26 weeks. The combined maximum across both types is 26 weeks per benefit year. PFML runs concurrently with federal FMLA for qualifying events.

Premium rates and employer obligations

Employers with 25 or more covered individuals must collect and remit both the employer share and the employee share. Employers with fewer than 25 covered individuals must withhold and remit only the employee share of 0.46%; they have no employer contribution obligation but may voluntarily cover more. All employers must post the annual PFML notice, provide written notice to employees at hire, and submit quarterly wage detail reports.

2026 updates

The maximum weekly benefit increases to $1,230.39 for 2026 based on the updated State Average Weekly Wage of $1,922.48. Per IRS Revenue Ruling 2025-4, employer-funded portions of PFML medical leave benefits are subject to federal employment taxes starting January 1, 2026. Employers must update their withholding calculations to account for this change. A 2025 amendment also permits employees to supplement PFML benefits with accrued sick or vacation time up to 100% of their pre-leave earnings.

Private plan option

Employers may apply for approval to substitute an approved private plan with benefits equal to or greater than the state plan. Private plans require DFML approval and must maintain equivalent or greater benefits. Employers with approved private plans may be exempt from state contributions while maintaining obligations to provide equivalent leave coverage.

Other Leave Requirements Beyond PFML

Massachusetts has a comprehensive set of leave requirements layered on top of PFML, including several that apply at the six-employee threshold of Chapter 151B. new hire paperwork and OSHA obligations add further layers to the compliance picture.

Parental leave

M.G.L. c. 149, § 105D requires employers with six or more employees to provide up to eight weeks of parental leave for birth, adoption, or placement of a child. The leave may be paid or unpaid at the employer's discretion. The law is gender-neutral since 2015. Two weeks' notice is required where practicable. This leave runs concurrently with PFML and federal FMLA for qualifying events. Employees must have worked at least three months in a full-time capacity to be eligible.

Small Necessities Leave Act

Employers with 50 or more employees (using FMLA's 75-mile radius criterion) must provide 24 hours of unpaid leave per year under M.G.L. c. 149, § 52D. This leave is for school activities of a child, routine medical or dental appointments for a child, and accompanying an elderly relative age 60 or older to medical or dental appointments. Employees may substitute accrued paid leave. This is in addition to, not subtracted from, FMLA entitlement.

Jury duty pay

Massachusetts requires employers to pay regular wages for the first three days of jury service under M.G.L. c. 234A, § 48. After three days, the Commonwealth pays $50 per day. All employers are covered with no size threshold. Retaliation for serving on a jury is prohibited under M.G.L. c. 268, § 14A.

Anti-Discrimination Under Chapter 151B

Chapter 151B is the primary Massachusetts anti-discrimination law, enforced by the Massachusetts Commission Against Discrimination (MCAD). More information at mass.gov/mcad.

Pregnancy accommodation

The Pregnant Workers Fairness Act (effective April 1, 2018, M.G.L. c. 151B, § 4(1E)) requires employers to provide reasonable accommodations for pregnancy, childbirth, and related conditions unless it would cause undue hardship. Four accommodations are available without requiring medical documentation: additional restroom, food, or water breaks; seating access; relief from lifting more than 20 pounds; and a private lactation space that is not a bathroom. Written notice must be provided to all new employees at hire and to any employee who notifies the employer of a pregnancy, within 10 business days.

CROWN Act

Signed July 26, 2022 and effective October 24, 2022, the CROWN Act expands the definition of race under Chapter 151B to include traits historically associated with race: hair texture, hair type, hair length, and protective hairstyles. Protective hairstyles are defined to include braids, locks, twists, Bantu knots, and hair coverings. Policies that prohibit these hairstyles in the workplace constitute racial discrimination under Massachusetts law.

Remedies

MCAD remedies include back pay, front pay, emotional distress damages, and attorney fees. Cases removed to Superior Court can include punitive damages with no cap in Massachusetts, and civil penalties of up to $50,000 for repeat offenders. Age discrimination cases carry liquidated damages of two to three times actual damages. These remedies significantly exceed what federal Title VII caps allow.

CORI, Ban-the-Box, and Background Check Compliance

Massachusetts has a comprehensive criminal record protection framework that applies to every stage of the hiring process and continues through employment.

The ban-the-box rule prohibits criminal history questions on the initial written application. At any stage of employment or hiring, employers may never ask about: arrests without a resulting conviction; first convictions for certain minor offenses (drunkenness, simple assault, speeding, minor traffic violations, affray, disturbance of the peace); misdemeanor convictions more than three years old; sealed or expunged records; and juvenile records. For records that can be considered, the lookback period under Standard CORI Access is 3 years for misdemeanors and 10 years for felonies. Consumer reporting agencies are limited to 7 years for criminal records under M.G.L. c. 93, § 52.

Before taking any adverse action based on criminal history, employers must conduct an individualized assessment considering the nature of the offense, time elapsed, and relationship between the offense and the specific job. The applicant must receive a copy of their CORI report before any adverse decision. Employers conducting five or more background checks per year must maintain a written CORI policy. The CORI system is accessed online through iCORI at a cost of $25 per check.

Non-Compete Reform: The Massachusetts Noncompetition Agreement Act

The MNCA at M.G.L. c. 149, § 24L took effect October 1, 2018 and fundamentally changed how non-compete agreements work in Massachusetts. It introduced requirements found almost nowhere else in the country.

The garden leave requirement is the most distinctive feature of Massachusetts non-compete law. During the restricted period, the former employer must pay the employee 50% of their highest annualized base salary within the two years preceding termination, on a pro-rata basis. The employer cannot unilaterally stop these payments except upon evidence of the employee's breach. An employer may alternatively provide "other mutually agreed upon consideration," but courts have scrutinized whether such alternatives are adequate. A 2025 case, Boyd v. Boston Beer, challenged a $3,000 payment as potentially inadequate.

Non-solicitation agreements covering customers, clients, and fellow employees are entirely excluded from the MNCA and continue to be governed by common law reasonableness standards. This was confirmed by the SJC in Miele v. Foundation Medicine Inc., 496 Mass. 171 (2025). NDAs, confidentiality agreements, and invention assignment agreements are similarly unaffected by the MNCA.

Specific professions are categorically prohibited from entering non-compete agreements by separate statutes: physicians (M.G.L. c. 112, § 12X), nurses, psychologists, social workers, and broadcasting employees.

Workers' Compensation and Workplace Safety

Massachusetts requires workers' compensation coverage for virtually every employer and has a state OSHA plan that applies only to public sector employers.

Workers' compensation (M.G.L. c. 152)

All Massachusetts employers with one or more employees must carry workers' compensation insurance. Domestic workers employed for 16 or more hours per week are covered. Corporate officers owning 25% or more of the corporation may elect to exclude themselves using Form 153. The First Report of Injury (Form 101) must be filed within 7 calendar days of the fifth missed workday. The penalty for operating without required coverage includes stop work orders, minimum fines of $100 per day (rising to $250 per day if appealing), up to one year of imprisonment and a $1,500 fine, and exclusion from public contracts for three years. The Department of Industrial Accidents (DIA) oversees workers' compensation.

OSHA coverage

Federal OSHA covers private sector employers in Massachusetts through area offices. Massachusetts established a state OSHA plan limited to public sector employers only, approved August 18, 2022. The plan is administered by the DLS Workplace Safety and Health Program under 454 CMR 25.00 and covers approximately 430,000 state and local government employees. Massachusetts is one of seven states and territories with a public-sector-only OSHA plan. Private sector employers deal with federal OSHA directly.

Required Workplace Postings

Massachusetts employers must display both state and federal required workplace posters. All state posters are available for free at mass.gov/info-details/massachusetts-workplace-poster-requirements.

Federal required postings include the FLSA Minimum Wage poster, EEOC Know Your Rights poster, federal OSHA Job Safety and Health poster, USERRA poster, and FMLA poster for employers with 50 or more employees. The PFML poster is updated annually; the 2026 version reflects the new maximum weekly benefit of $1,230.39.

Employee Privacy, Data Security, and Recording Rules

Massachusetts has three employee privacy rules that significantly exceed what most other states require: a felony recording consent standard, a mandatory written information security program for all employers, and a detailed personnel file access right.

All-party recording consent (M.G.L. c. 272, § 99)

Massachusetts prohibits secretly intercepting wire or oral communications. The key criterion is secrecy, not consent: if all parties to a conversation know that recording is occurring, it is lawful even if someone objects. If any party is unaware of the recording, it is a felony carrying penalties of up to $10,000 and five years in state prison. Civil liability adds a minimum of $1,000 or $100 per day per violation, plus punitive damages and attorney fees. For employers, this means no covert recording of calls, meetings, or conversations in any format. Security cameras with video only and posted notices are lawful; any audio capture requires that all parties in the space are aware of it.

Written Information Security Program (201 CMR 17.00)

Every person or organization that owns, licenses, stores, or maintains personally identifiable information of Massachusetts residents must have a comprehensive Written Information Security Program. This applies regardless of the employer's size, industry, or location. Personal information is defined as a Massachusetts resident's first and last name (or first initial and last name) combined with a Social Security number, driver's license or state ID number, or financial account number. Required WISP elements include a designated security officer, risk assessment, employee training, access controls, vendor management, encryption of portable devices, firewall protection, and annual review. Penalties under M.G.L. c. 93A reach $5,000 per violation, plus private class action exposure. For employee handbook, the WISP obligation applies because payroll records always include SSNs.

Personnel file access (M.G.L. c. 149, § 52C)

Current and former employees may request access to their personnel file up to twice per calendar year, with additional access whenever negative information is added to the file. Employers must provide access within five business days of a written request. When negative information is placed in an employee's file, the employer must notify the employee within 10 days. Employees may submit a written rebuttal to any disputed item. Employers with 20 or more employees must retain personnel records for at least three years after termination. Penalties range from $500 to $2,500 per violation, enforced by the AG.

Termination and Separation

Massachusetts termination rules are among the most unforgiving in the country because of the Wage Act's automatic treble damages for final pay violations.

Final paycheck

Discharged employees must be paid in full on the day of discharge, including all earned wages, accrued vacation per written policy, and earned commissions. For employees who quit, payment is due on the next regular payday or the following Saturday if there is no regular payday. Even one day late triggers mandatory treble damages. Corporate officers are personally liable. There is no exception for administrative delays, payroll system timing, or honest mistakes.

Health coverage continuation

Massachusetts mini-COBRA under M.G.L. c. 176J, § 9 applies to employers with 2 to 19 employees for insured group health plans. It provides 18 months of continuation coverage for most qualifying events, 36 months for divorce or death of the covered employee, and up to 29 months for disability. The premium may not exceed 102% of the group rate. A separate provision at M.G.L. c. 175, § 110G provides up to 39 weeks of continuation for involuntary layoffs at employers with 20 or more employees. Federal COBRA covers employers with 20 or more employees for 18 months standard.

Massachusetts WARN provisions

Massachusetts does not have a comprehensive state WARN Act. Federal WARN (29 U.S.C. §§ 2101–2109) applies to employers with 100 or more employees, requiring 60 days' notice for plant closings affecting 50 or more workers or mass layoffs of 50 or more workers representing at least one-third of the workforce, or 500 or more workers. M.G.L. c. 149, § 179B requires notification for business relocations affecting 12 or more employees. M.G.L. c. 151A, §§ 71A through 71G provide reemployment assistance programs; providing 13 weeks of notice reduces potential liability.

Payroll Tax and Registration Essentials

Massachusetts payroll registration requires registration with two separate state systems and incorporates the Millionaire's Tax surtax that affects withholding for higher-earning employees.

State income tax

Massachusetts imposes a 5.0% flat rate on wages, salaries, and Part B income under M.G.L. c. 62. Short-term capital gains are taxed at 8.5%; long-term collectibles at 12%. The Millionaire's Tax, approved by Massachusetts voters in November 2022 and effective for tax year 2023, adds an additional 4% surtax on income above $1,083,150 (the 2025 threshold, adjusted annually for inflation). The effective top rate on income above this threshold is 9%. Employers must factor this surtax into withholding calculations using the Circular M withholding tables.

Withholding forms and registration

Employers must collect Massachusetts Form M-4 from all new employees. The M-4 is exemption-based and functions differently from the redesigned federal W-4. Employees who claim exemption must recertify annually. Nonresident aliens use Form M-4A. If no M-4 is filed, withhold at zero exemptions. Employers register for withholding through MassTaxConnect at mtc.dor.state.ma.us, which also handles PFML contributions, sales tax, and corporate excise. UI registration uses a separate portal.

Unemployment Insurance

The Massachusetts UI taxable wage base for 2025 is $15,000 per employee per year. The new employer rate for 2025 is 2.13% (non-construction) or 5.45% (construction). For 2026, rates are projected to be approximately 2.42% and 6.08% respectively under Schedule F. EMAC surcharge of 0.34% applies to the first $15,000 in wages after the employer has been in business for five or more years. UI coverage is triggered when an employer pays $1,500 or more in any calendar quarter or has one or more employees for any portion of a day in each of 13 weeks in a year.

Boston and Local Requirements

Massachusetts cities operate under the Home Rule Amendment (Mass. Const. Art. 89), giving cities significant self-governance. However, local employment ordinances cannot conflict with state law, and most employment law in Massachusetts is preempted at the state level.

Cities cannot set local minimum wages above the state rate. Boston's Living Wage Ordinance (since 1997) requires $18.78 per hour as of July 2025 for employees of city contractors with contracts of $25,000 or more. This applies to contractors doing business with the city, not to all private employers in Boston. The Boston Resident Jobs Policy applies to large development projects over 50,000 square feet, not to typical private employers.

For most businesses with 5 to 50 employees in any Massachusetts city, state law governs all employment obligations. There are no significant additional local employment requirements beyond the state framework for typical private sector employers.

Massachusetts vs. Federal vs. New York

Massachusetts and New York are frequently compared as the two most employee-protective Northeast states. The table below shows where they diverge and where federal law provides the baseline.

Massachusetts stands apart from New York primarily in its all-party recording consent felony standard and its mandatory garden leave requirement for non-competes. New York's lower anti-discrimination threshold of four employees for NYSHRL is the primary area where New York is more protective on threshold coverage.

Key Dates: Massachusetts Employment Law Timeline

Massachusetts has seen significant legislative activity since 2010, with the pace accelerating from 2017 through 2026.

Frequently Asked Questions

Does Massachusetts require E-Verify for private employers?

No. E-Verify is voluntary for private employers in Massachusetts. Only state agencies are required to use it under Executive Order 2009-10. All employers must complete federal Form I-9 for every new hire within 3 business days of the employee's first day of work.

How soon must I pay a terminated employee in Massachusetts?

When an employee is discharged, their final wages must be paid on the day of discharge under M.G.L. c. 149, § 148. When an employee quits, payment is due on the next regular payday or the following Saturday. Any violation triggers mandatory treble damages plus attorney fees. There is no good faith defense, and even a one-day delay after discharge is a violation.

Do small employers with fewer than 25 employees pay the PFML employer share?

No. Employers with fewer than 25 covered individuals are not required to pay the employer share of 0.42%. However, all employers regardless of size must withhold the employee share of 0.46% and remit it to the DFML. Small employers may voluntarily cover part or all of the employee share. The combined rate for employers with 25 or more covered individuals is 0.88%.

Can I ask about criminal history on a job application in Massachusetts?

No. M.G.L. c. 151B, § 4(9½) prohibits any criminal history inquiry on the initial written application. Regardless of timing, you may never ask about arrests without conviction, sealed or expunged records, or most minor offense convictions. An individualized assessment is required before taking adverse action based on a criminal record.

Is a non-solicitation agreement subject to the MNCA garden leave requirement?

No. Non-solicitation covenants are explicitly excluded from the MNCA under § 24L(a) and are governed by common law standards of reasonableness. This was confirmed by the SJC in Miele v. Foundation Medicine Inc., 496 Mass. 171 (2025). NDAs and confidentiality agreements are also excluded from MNCA requirements.

Do I need a Written Information Security Program (WISP)?

Yes, if you store personally identifiable information of Massachusetts residents. Under 201 CMR 17.00, this requirement applies to every employer regardless of size or location that stores employee records containing SSNs, driver's license numbers, or financial account numbers combined with the employee's name. Penalties reach $5,000 per violation under M.G.L. c. 93A.

Does the pay transparency law apply to my 20-person company?

The pay range disclosure requirement effective October 29, 2025 applies to employers with 25 or more employees. A 20-person company is not subject to the posting requirement. However, the salary history ban under M.G.L. c. 149, § 105A applies to all Massachusetts employers regardless of size: you cannot ask any applicant about prior salary before making an offer.
