Hiring your first employee in Massachusetts

What do you have to register for before your first payroll?

One registration with the Department of Revenue opens your withholding account, your sales and use tax account and your paid family and medical leave account, so you do not register three separate times for those. Unemployment insurance is not part of it: that is a separate registration with the Department of Unemployment Assistance in its own system. Workers compensation is not a state account at all, it is a policy you buy from a private insurer. Budget for three errands, not one.

Does Massachusetts require income tax withholding?

Yes. You register with the Massachusetts Department of Revenue, before the business opens and before your first massachusetts payroll.

You must withhold from every Massachusetts resident you employ, on wages for work done inside or outside the state, and from nonresidents on wages for work performed in Massachusetts. The rule that catches out-of-state companies is the reverse case: if your only link is employing a resident who works entirely outside the state you do not have to withhold, but the moment that person works in Massachusetts you do. Once registered you must file quarterly wage reports for every period even if you withheld nothing, so an account left open quietly generates late filing penalties.

What unemployment insurance does Massachusetts charge a new employer?

A new Massachusetts employer pays 2.42% on the first $15,000 each employee earns, so roughly $363 per employee in the first year. For 2026 a new employer pays 2.42% on the first $15,000 of wages, and a new construction employer pays 6.08%. New employers are exempt from the recovery assessment that experience-rated employers pay on top, so the headline number is the whole bill for the first three years. The wage base is fixed in statute rather than reset annually, but the rate is reset each year. Separately, Massachusetts charges an employer medical assistance contribution on the same first $15,000: you are exempt for roughly your first three years and while under six employees, then pay 0.12% in year four, 0.24% in year five and 0.34% from year six, a cost that appears years after you thought your payroll maths was settled.

Do you need workers compensation insurance in Massachusetts?

Yes, from your first employee. Massachusetts sets no headcount to reach, so there is no free window before coverage is required.

Massachusetts gives you no free headcount and no hours minimum: coverage is required for every employee from the first one, part time included. The only carve outs are domestic workers below 16 hours a week, and owners covering themselves. Out-of-state employers with anyone working in Massachusetts must cover them here, and an all-states endorsement is not enough on its own: your carrier has to make a specific Massachusetts filing. Going without triggers a stop work order at $100 a day including weekends, rising to $250 a day if you appeal, plus three year debarment from public contracts.

How quickly must you report a new hire in Massachusetts?

Within 14 days of the start of, or return to, employment. Reports go to the Massachusetts Department of Revenue, Child Support Services Division.

Fourteen days rather than the twenty most states allow, so diarise it if you are used to the longer window. Massachusetts also asks for more than new employees: you report anyone returning after 30 or more days off the payroll, retiring employees, employees who file workers compensation claims, and independent contractors you expect to pay $600 or more in a year. The penalty is up to $25 each, but $500 per person if the omission was agreed with the worker. Employers with 25 or more employees must file electronically.

Does Massachusetts have paid family leave or state disability insurance?

Headcount decides whether you pay any of this. An employer with 25 or more covered individuals sends 0.88% of eligible wages in total: you may withhold up to 0.46% from the worker and owe the remaining 0.42% yourself. Below 25 covered individuals you owe nothing of your own and simply remit the 0.46% withheld, so hiring your 25th covered individual adds a real employer cost. Contributions stop at the Social Security wage maximum, rates are reset every October for the following year, and a 2026 law reshuffles the employer share between medical and family leave from January 2027.

Do you need a sales tax permit in Massachusetts?

You register as a vendor online and the state mails you a registration certificate which you must display at each location. No fee is charged in the online application, but the statute lets the Commissioner of Administration set one and the Department never states that registration is free, so no amount is published here. Remote sellers and marketplaces file monthly rather than on the smaller-vendor schedule, and if all your sales turn out to be exempt you still owe an annual return showing zero.

Does a marketplace like Amazon or Etsy handle the tax for you?

A platform collects and remits the tax on the sales it facilitates for you once its own combined Massachusetts sales pass the remote seller threshold. Get the platform's collection certificate and keep it: accepting it in good faith is what releases you from liability on those sales, and it also lets you leave those sales out of your own threshold count. The trap is that your direct sales still count on their own, so a seller comfortably covered on marketplace orders can still trip into a registration duty through its own website.

If your sales drop, when can you stop collecting?

Massachusetts tests both the prior and the current calendar year, which produces trailing nexus without ever calling it that. Cross the threshold in one year and you collect for the whole of the next even if your sales collapse, and only after a full year back under the line does the duty lapse. Note also that lapsing out does not close your account: a registration stays open until you cancel it or file a return marked final, and an open account keeps generating filing obligations.

Does Massachusetts charge a tax on revenue rather than profit?

Massachusetts has no gross receipts tax of the Washington or Ohio kind. What businesses owe instead is the corporate excise, charged on net income and on tangible property or net worth rather than on total revenue, so costs and expenses do reduce it. If you are comparing states on the assumption that a sales tax state has no second business-level tax, check the corporate excise before concluding Massachusetts is cheaper than a gross receipts state.

Do you have to register your out-of-state company in Massachusetts?

A foreign LLC pays $500, fixed by statute. A foreign corporation pays $400. Neither filing can be done online, and both need a certificate of good standing from the home state less than 90 days old.

The deadline is the part people miss: a foreign LLC must register within ten days after it commences doing business in Massachusetts, far tighter than most states. The ongoing cost is unusually high too, because a foreign LLC pays $500 again for every annual report, while a foreign corporation's annual report is $125. Registering with the Corporations Division is a separate step from your tax and unemployment accounts and does not register you for any tax.

Where these figures come from

Every number on this page was read on Massachusetts's own agency pages, its statute, or a current-year official form, and this record was last reviewed on 2026-09-08. Where a state's explainer page disagreed with its statute or its current form, we followed the statute or the form and said so in the relevant section, because a state's consumer-facing pages are often the last thing updated when a figure changes.

Anything we could not confirm on a primary source is left blank rather than estimated. A missing figure on this page means we could not verify it, not that it is zero.

This is general information, not legal or tax advice. Rules change and your circumstances matter. Confirm anything you are about to act on with the agency named beside it.
