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.

I built FirstHR because a business without a dedicated HR person keeps dropping this kind of sequence. 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.

The Massachusetts Hiring Sequence at a Glance

Every item below is a legal obligation with a named enforcing body and a stated consequence. Six of them 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 rest of this guide walks each step in the same order, calling out where Massachusetts departs from the generic national advice on hiring your first employee. Leave, termination, and recordkeeping obligations that arrive after the hire sit in the Massachusetts compliance hub.

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. Founders who try to run the state registrations in parallel with the EIN application almost always restart one of them, because the identification screen comes first rather than last. 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 three separate 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. The full Massachusetts tax picture, including rates and filing cadence, sits in the Massachusetts payroll guide.

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 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 under one of two tests. A private for-profit employer contributes to the trust fund if it has 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 those weeks do not have to be consecutive, or if it pays 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. The department assigns a rate and 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. The quarterly employment and wage detail report and the contribution are both due by the last day of the month after the quarter closes, meaning 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 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. Reports and payments are filed quarterly for the previous calendar quarter.

How much of the contribution you carry depends on your size. For 2026 the total rate for an employer with 25 or more covered individuals is 0.88 percent of eligible wages, split between a medical leave contribution of 0.70 percent and a family 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 is not required to pay the employer share of the medical leave contribution and is only sending 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. The benefit side of the program is covered in the guide to Massachusetts paid family leave.

One change is already on the calendar. Chapter 101 of the Acts of 2026, signed June 12, 2026, restructures the contribution so that no employer contribution funds medical leave benefits, effective January 1, 2027, and the department sets the new rate on or before October 1 of the preceding year. Small employers were never paying that employer share, so the practical routine below does not change. 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 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.

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 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 general rules of what a job posting must contain apply on top.

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. You can still raise the subject later in the process and run a lawful background check. The rule is about what appears on the application, and the usual failure is a checkbox inherited from an out-of-state template.

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 is the most commonly missed step in the sequence.

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

Massachusetts has a state income tax, so a new hire completes two withholding forms rather than one. Federal Form W-4 sets federal withholding. Massachusetts Form M-4 sets state withholding and is the form the Department of Revenue expects on file, particularly where the employee claims a different number of exemptions for state purposes than for federal ones.

Collect both before day one rather than on day one. Everything on the list below except the employer half of the I-9 can be completed digitally 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 as well as employees, and it covers anyone returning to your payroll after 30 or more days away. 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 the FLSA, OSHA, the Employee Polygraph Protection Act, and USERRA. Every one 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. Each new employee must receive the paid family and medical leave notification within 30 days of the start date, on paper or electronically. Under the statute, delivery is made only when the employee provides written acknowledgment of receipt or signs a statement recording a refusal to acknowledge, so one of those two documents has to come back and go 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 are collected digitally before day one. The system holds the reminders for the three-business-day I-9 deadline, 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, hourly employees are paid weekly or biweekly, and 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 working seven days or fewer than five. An employer cannot contract out of that schedule with an employee.

Separation is where that strictness is sharpest. An employee who is discharged must be paid in full on the day of discharge, including accrued unused vacation, 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 size thresholds arrive earlier in Massachusetts than founders expect. 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. That default 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.

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 tied to city contracts, which reach private employers only through the contracting relationship 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 contract, not the address, so it lands on a private employer only when that employer holds or subcontracts under covered city work. Pull the current published rate from the city before you price the labor, because the ordinance rate is set independently of the state floor.

The practical rule is short. Comply with Massachusetts state law everywhere in the Commonwealth, and layer a city ordinance on top only where you actually hold the contract that triggers it. 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 single sentence resolves the majority 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 is a few percentage points of payroll. 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. Each is a sequencing error rather than a knowledge gap. 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.
