Hiring a nanny or housekeeper in Massachusetts triggers real insurance and legal obligations.

Do you need workers’ comp for a nanny or housekeeper in Massachusetts

The answer turns on one number: 16 hours a week. Massachusetts workers’ compensation law, M.G.L. c.152 §1(4), defines an employee broadly as “every person in the service of another under any contract of hire.” The statute then carves out a single exception, making coverage optional only for “seasonal or casual or part-time domestic servants,” and it defines part-time as working less than sixteen hours per week for that employer. Mass.gov states this plainly for consumers: the workers’ compensation requirement applies regardless of the number of hours worked, except domestic service employees, who must work a minimum of 16 hours a week before coverage becomes mandatory. The Department of Industrial Accidents’ guidance repeats the same line, calling it the only exception to the general rule.

Separately, the Domestic Workers’ Bill of Rights (M.G.L. c.149 §190(a), enacted by Chapter 148 of the Acts of 2014) defines who counts as a domestic worker in the first place: someone paid to perform work of a domestic nature in a household, including housekeeping, house cleaning, home management, nanny services, caretaking of individuals in the home, laundering, cooking, and home companion services. Casual babysitters are treated as a separate category and generally work fewer than 16 hours a week for a given household, which is exactly the population the workers’ comp exception is built for.

So if your nanny, housekeeper, or home companion works 16 hours or more a week for your household, you are required by law to carry workers’ compensation insurance for them. Under M.G.L. c.152 §25A, sole proprietors, which includes an individual household employer, are required to provide this coverage.

What happens if your household employee gets hurt and you’re not covered

Two separate consequences follow an uncovered injury, and neither is small. First, the Department of Industrial Accidents’ Office of Investigations can issue a stop-work order and assess a minimum fine of $100 per day, starting on the date of issuance and accruing daily until coverage takes effect. That penalty compounds for every day you remain uninsured after the order.

Second, and more directly relevant to the injured worker, Mass.gov’s domestic-worker guidance warns that even without employer coverage, a domestic worker who misses more than 5 calendar days of work due to a work-related injury or illness may still be able to obtain compensation for medical care and lost wages through the DIA. Workers’ compensation normally pays for reasonable and necessary medical treatment plus partial wage replacement after the first 5 calendar days of disability. Skipping coverage doesn’t eliminate that liability; it means you, personally, may be on the hook for it outside the structure a policy would otherwise provide.

Why treating your nanny as a 1099 contractor doesn’t hold up

Some households try to sidestep the coverage question by paying a nanny as an independent contractor. Under M.G.L. c.149 §148B, Massachusetts starts from a presumption that a worker is an employee. To rebut that presumption, an employer has to show, among other factors, that the work is done without the employer’s direction and control and that it’s performed outside the usual course of the employer’s business. A nanny working in your home, on your schedule, caring for your children, is a difficult fit for that test.

Mass.gov is candid that there’s no simple rule of thumb here; the determination is a question of fact reviewed case by case. If a formal determination is needed, the mechanism is federal Form SS-8, Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding. Calling the arrangement a 1099 relationship doesn’t change the underlying facts, and if a nanny is later found to be a misclassified employee, the workers’ comp exposure discussed above applies retroactively to the period she should have been covered.

Unemployment insurance and other obligations that ride along with workers’ comp

Workers’ comp isn’t the only compliance thread. Domestic employers must contribute to Massachusetts unemployment insurance once they’ve paid $1,000 or more in cash wages to domestic workers in any calendar quarter. Once registered, you file quarterly employment and wage detail reports with contributions due by set deadlines: Quarter 1 by April 30, Quarter 2 by July 31, Quarter 3 by October 31, and Quarter 4 by January 31, each due by 3 p.m. Late payments carry a steep 12% interest rate until paid in full.

On the tax side, the Social Security and Medicare (FICA) rate is 7.65% for the employer and 7.65% for the employee, and as the household employer, you’re responsible for paying the employee’s share as well as your own. You’ll also need the worker to complete the employee portion of federal Form I-9 and keep the employer portion on file. None of this is optional paperwork you can defer; it’s the baseline administrative layer sitting underneath the insurance requirement.

Written agreements, pay, and rights under the Domestic Workers’ Bill of Rights

The same 16-hour threshold that triggers workers’ comp also triggers a written-agreement requirement. Domestic workers who work 16 or more hours a week must be given a written agreement, in a language they understand, signed by both parties, and made before work begins; you must keep it on file for at least 3 years. Domestic workers also have the right to review and correct their timesheets at least every two weeks, and to earn 1 hour of sick time for every 30 hours worked, up to 40 hours a year, usable starting 90 days after their first day. These protections apply regardless of immigration status.

Live-in arrangements carry additional obligations at termination. If you end a live-in worker’s employment, you must provide at least 30 days of housing at the current or similar location, or severance equal to 2 weeks of average pay. If you instead relocate or pay severance rather than let the worker stay, you must give at least 24 hours to move out; even for-cause terminations require a reasonable opportunity of at least 48 hours to vacate. All earned wages, including unused paid vacation time, are due on the last day of work regardless of why employment ended.

Where homeowners insurance stops and workers’ comp starts

This is the gap most households never think to check. Whether a standard homeowners policy’s personal liability or medical-payments coverage responds to a bodily-injury claim from an injured nanny or housekeeper, and whether carriers require a separate residence-employee or employer’s-liability endorsement, isn’t confirmed on a Massachusetts Division of Insurance page in current research. If you want to understand what your homeowners policy actually does cover, how home insurance works in Massachusetts is a useful baseline, but it isn’t a substitute for a dedicated workers’ compensation policy once your household employee crosses the 16-hour line. The mechanism that pays medical bills and lost wages for a household-employee injury is workers’ comp, not your homeowners liability limit; treat them as separate purchases rather than assuming one absorbs the other.

How to get covered: next steps for Massachusetts households

Start by counting actual hours worked per week for your household, not scheduled hours. If you’re at or approaching 16 hours, put a written agreement in place before that threshold is crossed and begin the process of binding a workers’ compensation policy. Register as a household employer with the Department of Revenue and the Department of Unemployment Assistance if you expect to cross the $1,000 quarterly wage threshold, since UI obligations run on a separate clock from workers’ comp. A broker who works across carriers can shop a household-employer workers’ comp policy that fits a single-employee arrangement, which is a different underwriting profile than a small business policy. Our Workers’ Compensation team places this coverage directly, and if you’re reviewing your broader household insurance picture at the same time, a personal insurance quote is the right starting point.
