How to Hire Employees in Massachusetts: The Complete Compliance Sequence

The first Massachusetts hire I watched go sideways was not a bad hire. The founder had a signed offer letter, a start date, and a payroll app ready to run. What he did not have was a workers compensation binder, because the broker was waiting on a classification code, and the employee had already worked four days by the time the policy took effect.

Nothing happened in those four days. No injury, no claim, no inspection. But an uninsured week in Massachusetts is a stop work order waiting for the wrong visit, and it is entirely avoidable by moving one date. That is the pattern in this state. The rules are not obscure. They are simply strict, they sit at five different state agencies, and they punish sequencing errors harder than most states do.

Below is the full Massachusetts order of operations for a first hire, with the deadline and the exposure attached to each step, checked against the agency or the statute that governs it. I built FirstHR because a business without a dedicated HR person keeps dropping this kind of sequence.

The Massachusetts Hiring Sequence at a Glance

Eleven of the twelve items below are legal obligations with a named enforcing body and a stated consequence. The twelfth is the onboarding plan you set for yourself. Six of the twelve land before you have a candidate in hand, three cluster at offer and start, and the rest run out through the first 90 days.

The ten steps that follow cover all twelve items in the same order, calling out where Massachusetts departs from the generic national advice on hiring your first employee.

Step 1: Get Your Federal Employer Identification Number

Start with the federal Employer Identification Number, because every Massachusetts registration that follows asks for it on the first screen. The EIN is how the IRS identifies your business on employment tax returns and deposits. Apply through the IRS online application and the number is issued at the end of the session.

If you formed an LLC or a corporation and already hold an EIN, reuse it. If you have been operating as a sole proprietor and filing under your Social Security number, you need one now. Payroll tax deposits cannot be made against a personal Social Security number, and none of the Massachusetts accounts will open without an EIN in hand.

Finish this before touching anything else. A state registration started before the EIN arrives stalls at its first screen, which asks for the number, and has to be restarted. The EIN is also the number your insurance broker will ask for on the workers compensation application, so getting it out of the way removes a dependency from four later steps at once.

Step 2: Open Your Massachusetts Withholding Account

Massachusetts has a state income tax, so the second step is registering with the Department of Revenue to withhold it. Registration runs through MassTaxConnect, the online portal the department uses for business tax accounts. An employer registered to withhold must file the required returns whether or not tax was actually withheld during the period, which surprises founders who assume a quiet quarter means nothing to file.

Do this before the first payroll rather than after it. Withholding is a trust obligation: the money belongs to the Commonwealth from the moment it leaves the paycheck, and late remittance carries interest and penalties even when the underlying calculation was correct.

One detail saves real time later. MassTaxConnect is also the portal for paid family and medical leave contributions and for the new hire report, so the account you open here becomes the front door for three separate obligations. Unemployment insurance is the exception, and it lives somewhere else entirely.

Step 3: Open Your Unemployment Insurance Account

Unemployment insurance is a separate registration with a separate agency. You register with the Department of Unemployment Assistance (DUA) through its employer services portal, and the account number you receive is used on every quarterly employment and wage detail report you file.

You become a subject employer, one that must contribute to the state unemployment trust fund, under one of two tests. For a private for-profit employer, the first is time: one or more employees working on a permanent, temporary, or part-time basis at least one day a week for a minimum of 13 weeks in a calendar year, and the weeks do not have to be consecutive.

The second test is payroll: wages of $1,500 or more in any quarter. A single ordinary hire clears one of those tests almost immediately, so the practical answer for a first-time employer is to register at the point of hire rather than wait for a threshold to be crossed on paper.

New employers do not choose their unemployment contribution rate. According to the Department of Unemployment Assistance, the 2026 new employer rate is 2.42 percent, or 6.08 percent for a new employer in construction, and the department recalculates it once your own claims history matures.

What is fixed is the base the rate applies to. Contributions are charged on the first $15,000 of each employee’s wages in a calendar year, and the quarterly employment and wage detail report and the contribution are both due by the last day of the month after the quarter closes: April 30, July 31, October 31, and January 31.

That wage base changes how the cost behaves over the year. Because contributions stop once an employee crosses $15,000, unemployment tax is front-loaded into the first months of the year for a salaried hire and spread across more of the year for a part-time one. Budgeting it as a flat percentage of annual payroll overstates the fourth quarter and understates the first.

Step 4: Register for Paid Family and Medical Leave Contributions

Massachusetts runs a state paid family and medical leave (PFML) program, and the contribution obligation reaches employers of every size. Registration and payment run through MassTaxConnect, because the Department of Revenue administers and collects the contributions on behalf of the Department of Family and Medical Leave (DFML). Reports and payments are filed quarterly for the previous calendar quarter.

How much of the contribution you carry depends on your size. According to the Department of Family and Medical Leave, the total rate for an employer with 25 or more covered individuals is 0.88 percent of eligible wages, effective January 1, 2027, split between a family leave contribution of 0.70 percent and a medical leave contribution of 0.18 percent.

An employer with fewer than 25 covered individuals remits an effective rate of 0.46 percent, because a small employer owes no employer share and only sends along the amounts withheld from covered individuals.

For a business making its first hire, the translation is short. You sit on the small employer side of that rule, you withhold the employee share from wages, and you remit it quarterly. Skipping the deduction does not save money. It leaves you owing the contribution anyway, out of your own pocket, for every quarter you failed to withhold.

Chapter 101 of the Acts of 2026, signed June 12, 2026, puts the employer share on family leave from January 1, 2027. Employers with 25 or more covered individuals pay 60 percent of the family leave contribution, and employees may be charged up to the full medical leave contribution.

DFML publishes each year’s rate by October 1 of the year before. Small employers owe no employer share at all, so the change leaves the routine above untouched for a first hire. Check the published rate each January before you run the first payroll of the year.

Step 5: Put Workers Compensation Coverage in Force

Massachusetts requires workers compensation insurance from the first employee, and coverage is not elective. Every employer operating in the Commonwealth must carry it for its employees regardless of the number of hours worked or the number of people employed, and for themselves where they are an employee of their own company. Employer guidance and coverage requirements are published by the Department of Industrial Accidents.

The exceptions are narrow and they run to owners, not to the people you hire. Members of an LLC, partners in an LLP, and sole proprietors of an unincorporated business are not required to cover themselves, and a corporate officer who owns at least 25 percent of the corporation can request an exemption. Neither route touches the obligation to cover everyone else on the payroll.

The obligation attaches to the work rather than to the payroll date, so the policy has to be active before the employee performs anything at all. This is the step that produced the four uninsured days in my opening story, and it is the one I now treat as a hard gate on the start date.

Two questions come up here for almost every first-time employer. The first is what the policy actually buys. Workers compensation pays medical care and partial wage replacement for a work injury, and in exchange it channels the claim into an administrative system instead of a lawsuit. Without coverage the claim still arrives, you pay it directly, and the penalty lands on top.

The second question is what drives the premium. Payroll and the classification code that describes the work do, which means a warehouse role and a desk role at the same salary do not cost the same to insure.

Price the coverage before you finalize the wage. A quote obtained during the offer stage keeps the total cost of the hire honest and removes the temptation to let the start date run ahead of the binder. It also gives the broker time to resolve the classification question that is usually the real cause of the delay.

That is the whole setup layer: one federal number, three state registrations across two portals, and a policy that has to bind before the first hour. The failure is almost never that a founder did not know about one of them, it is that nobody wrote down which ones came back. The record below holds a line for each, with room for the number, the date it was issued, and the confirmation that closes it, plus the gate that keeps the start date behind the binder.

Step 6: Fix the Posting and the Application Before You Screen Anyone

Three Massachusetts rules govern what you may publish and what you may ask, and all three bite before an offer is ever made. Getting them right costs nothing at the drafting stage and is expensive to unwind afterward.

The first is pay transparency. Beginning October 29, 2025, an employer with 25 or more employees in the Commonwealth must disclose the pay range in a job posting, must provide it to an employee who is offered a promotion or transfer, and must provide it on request to an applicant or a current employee.

A pay range is the annual salary range or hourly wage range the employer reasonably and in good faith expects to pay for the position at that time. The Attorney General enforces it on a ladder: a warning for a first offense, a fine of not more than $500 for a second, not more than $1,000 for a third, and the citation penalties of Chapter 149, section 27C after that.

The second is criminal history. Chapter 151B prohibits requesting criminal record information on an initial written application form, subject to narrow exceptions where a law creates a mandatory or presumptive disqualification for the position.

Some questions stay closed at every stage, not just on the form. According to the Attorney General, most employers may never ask about an arrest or case that ended without a conviction; a first conviction for drunkenness, simple assault, speeding, minor traffic violations, affray, or disturbance of the peace; juvenile court records; or sealed and expunged records.

The same bar covers a misdemeanor conviction where the conviction or the release from incarceration came three or more years before the application, unless the person was convicted of another offense within those three years. Felony convictions and other misdemeanors can come up later in the process, and you may run a lawful background check once they do.

The trap is the application form itself. The usual failure is a conviction checkbox inherited from an out-of-state template, sitting on page one of an online application nobody has reread since the day it was built.

The third is pay history. The Massachusetts Equal Pay Act prohibits seeking the wage or salary history of a prospective employee, either from the applicant or from a current or former employer, before an offer of employment with compensation has been negotiated and made. If the applicant volunteers the figure, you may confirm it.

A salary expectations field that asks what someone currently earns is the version of this that gets copied into application forms without anyone noticing.

Step 7: Complete Form I-9 by the Third Business Day

Every employer in the United States must complete Form I-9 for every new hire to verify identity and authorization to work. Massachusetts adds nothing to the federal requirement, but the deadline is tight enough that this step is easy to miss.

The employee completes Section 1 no later than the first day of work. You complete Section 2 within three business days of the start date by examining original documents the employee chooses to present. You cannot tell the employee which documents to bring. Specifying documents is its own violation, separate from any deadline problem.

E-Verify is a separate federal system that checks the data on a completed I-9 against government records. Massachusetts does not require private employers to use it, and enrolling never replaces the I-9 itself. Federal contractors and subcontractors whose contracts carry the Federal Acquisition Regulation E-Verify clause have their own obligation regardless of what state law says.

The reason this step deserves a calendar entry rather than a mental note is arithmetic. Federal civil money penalties for I-9 violations are assessed per form and per employee rather than per audit, and paperwork errors are cited even when every worker turns out to be authorized.

A remote or hybrid hire adds a wrinkle, because someone has to examine the documents in person or through an authorized alternative procedure, and deciding who that is on day three is too late.

Step 8: Collect the Withholding Forms Before the First Paycheck

A new hire completes two withholding forms in Massachusetts rather than one, because the state taxes income as well. Federal Form W-4 sets federal withholding.

Massachusetts Form M-4 sets state withholding, and the Department of Revenue expects every employee to file one with the employer. The form says it plainly: if the employee does not file a certificate, the employer must withhold on the basis of no exemptions, which is rarely what the employee wanted.

Collect both before day one rather than on day one. Every employee form in the table below can be completed in advance, which turns the first morning into an introduction to the work instead of an hour of forms. That sequencing is the entire point of structured new hire paperwork.

Step 9: File the New Hire Report Within Fourteen Days

Massachusetts gives you 14 days. Every employer must report a newly hired employee to the Department of Revenue within 14 days of the first day of work, and the requirement applies regardless of how many people you employ. Filing options and the reporting form are published on the state new hire reporting page.

The obligation is broader than the phrase "new hire" suggests. It covers independent contractors paid $600 or more in a year as well as employees, and it covers anyone reinstated after a lapse in pay of 30 calendar days or more. A paid probationary period does not pause the clock either: if the person is being paid, the report is due within 14 days of the first day of work.

The penalty is modest per person and unpleasant in volume. The regulation at 830 CMR 62E.2.1 allows up to $25 for each employee, independent contractor, or other recipient of periodic income who is not reported or is reported inaccurately, and $500 per person where the failure results from a conspiracy between the employer and the worker.

Step 10: Post the Notices and Onboard Through Day 90

Two things happen at the start date. The required notices go up and go out, and the actual onboarding begins. The notices are largely a one-time setup task. The onboarding is where the money you just spent on hiring either returns or evaporates.

Massachusetts employers display both federal and state notices where employees can see them. The state set includes the Wage and Hour Laws poster and the Earned Sick Time notice of employee rights from the Attorney General, the Fair Employment Law poster from the Massachusetts Commission Against Discrimination, the paid family and medical leave workplace poster from DFML, the notice on unemployment insurance coverage from DUA, and the Notice to Employees from the Department of Industrial Accidents.

Federal notices cover wage and hour rules (FLSA), workplace safety (OSHA), the Employee Polygraph Protection Act, and military service rights (USERRA). Every notice, state or federal, is published free by the agency behind it, so there is no reason to buy them from a vendor.

One Massachusetts notice is individual rather than posted, and it is the one that gets missed. According to the Department of Family and Medical Leave, each new employee must receive the paid family and medical leave notification within 30 days of hire, on paper or electronically, with the opportunity to accept or decline receipt.

Under the statute, delivery is made when the employee signs a written acknowledgment of receipt or a statement refusing to sign one. If neither comes back, DFML treats the duty as met when you can show you gave the notice and that opportunity, so keep the signed form or the record of your attempt in the file.

I built the AI onboarding wizard in FirstHR for exactly this stretch. The offer letter goes out with e-signature. The I-9, W-4, and M-4 go on the new hire’s first-day list as tasks. The forms themselves are completed outside the platform, and the finished copies are kept in the employee file.

Tasks with deadlines can carry the 14-day new hire report and the 30-day paid leave notice, and the wizard turns the job description into a 30-60-90 day plan instead of leaving the first quarter to improvisation.

Massachusetts Rules That Change How You Employ People

Six Massachusetts rules reshape the employment relationship once the hire is complete. Each differs enough from the generic national picture that copying a handbook or a pay calendar from another state produces a compliance gap on arrival.

The Wage Act deserves the most attention, because it converts an ordinary administrative slip into a multiple of the underlying amount. Wages must be paid on time, and hourly employees are paid weekly or biweekly.

Payment must reach the employee within six days of the end of the pay period for someone working five or six days in a calendar week, or within seven days for someone who works all seven days or fewer than five. An employer cannot contract out of that schedule with an employee.

Separation is where that strictness is sharpest. A discharged employee is owed full pay on the day of discharge, accrued unused vacation included, while an employee who resigns is paid on the next regular pay day.

In Reuter v. City of Methuen the Supreme Judicial Court held that an employer who pays late is strictly liable for treble damages, even where the wages were paid in full before any complaint was filed. Decide the final paycheck math before the separation meeting rather than after it.

Two laws apply at a lower headcount in Massachusetts than founders expect, and both start at six employees. Chapter 151B, the state anti-discrimination statute enforced by the Massachusetts Commission Against Discrimination, applies to employers with six or more employees, well below the federal threshold.

The Massachusetts Parental Leave Act sits at the same size and gives eligible parents eight weeks of leave per child, with a right to return to the same or a similar position. Both arrive during the stretch when most businesses still think of themselves as too small to have HR obligations.

Employment in Massachusetts is at will, subject to the usual statutory and public policy limits, which means neither party needs a reason to end the relationship.

At-will status is easier to lose than to keep. Handbook language promising progressive discipline, a probationary period that graduates into permanent status, or a closed list of reasons for termination can each be read as a contractual limit, which is why the employee handbook is worth drafting carefully rather than assembling from templates.

What worked for me

The habit that fixed the most for me was moving the workers compensation binder ahead of the offer letter instead of behind it. The broker needs a classification code and a payroll estimate, both of which exist at the offer stage, and the quote then tells you the real cost of the role before you commit to a number. It also removes the temptation to start someone on Monday when the policy binds on Wednesday.

City Requirements: Boston and Cambridge

No Massachusetts city or town has enacted its own minimum wage for private employers, so the $15.00 state floor applies everywhere in the Commonwealth. What Boston and Cambridge do have are living wage ordinances, which reach a private employer through its business with the city, such as a covered city contract, rather than through geography.

Each city applies its living wage to eligible employees of vendors holding covered city service contracts and subcontracts above a contract value threshold set in the ordinance, at a rate the city publishes and revises on its own schedule. The duty follows the city business, not the address, so an office in Boston or Cambridge does not trigger it on its own.

The ordinance rate is set independently of the state floor, so pull the current published rate from the city before you price the labor.

The practical rule is short. Comply with Massachusetts state law everywhere in the Commonwealth, and layer a city ordinance on top only where your dealings with the city trigger it, such as a covered contract.

Remote arrangements are where this gets slippery, because wage and hour obligations tend to follow the place the work is performed rather than the address on your business certificate. If a hire will work from a different state, price and register for that state before the offer goes out.

Employee or Independent Contractor: Massachusetts Uses the Strictest Test

Massachusetts applies the ABC test in Chapter 149, section 148B, and all three prongs must be satisfied for a worker to be treated as anything other than an employee. The burden sits on the employer, and failing any single prong is enough to make the person an employee.

The second prong is what makes this test different from the federal common law analysis, and it is where most classifications collapse. If the service the person performs is the thing your business sells, no amount of scheduling freedom rescues the classification. That one test settles many of the close calls a small business faces.

Three consequences follow a reclassification, and employers usually anticipate only one. The unemployment side brings back contributions with interest for the whole period. The tax side brings unpaid withholding. The wage and hour side brings Wage Act exposure with its mandatory treble damages and attorney fees, and the same facts tend to produce a workers compensation coverage finding for the identical period.

The guidance is not complicated. Run the three prongs in writing before anyone is paid on a 1099, keep the analysis with the contract, and if any prong is arguable, hire the person as an employee. The cost difference between a properly classified employee and contractor comes down to the employer’s payroll taxes and insurance. The cost difference between a correct classification and a wrong one runs across three agencies at once.

The Mistakes That Cost Massachusetts Small Businesses the Most

These are the failures that repeat at Massachusetts businesses making a first or second hire. Most are sequencing errors rather than knowledge gaps. The employer knew the rule and ran the steps in the wrong order, or carried a habit across a state line.

The common thread is that compliance fails on the calendar, not in the reasoning. Nobody sets out to run an uninsured week or to pay a final check three days late. The task simply arrives during a stretch when the founder is doing four other jobs. That is why reminders and task workflows do more good at this scale than another compliance summary would.
