The short answer Massachusetts layers a pre-ACA state individual mandate, Form MA 1099-HC, the annual HIRD report, and PFML on top of federal rules, with the Health Connector as its exchange.
What Massachusetts requires
Massachusetts
Exchange. Massachusetts runs the Health Connector, the nation's oldest exchange, with ConnectorCare subsidized plans.

State individual mandate & MA 1099-HC. Massachusetts has had its own individual mandate since 2006. Residents need Form MA 1099-HC (furnished by January 31); carriers typically issue it for insured plans, but employers with self-insured plans are responsible for ensuring Massachusetts employees receive it and data reaches DOR.

HIRD report (due Dec 15). Every employer with 6+ Massachusetts employees must file the annual Health Insurance Responsibility Disclosure (HIRD) through MassTaxConnect between November 15 and December 15 each year, reporting plan details used for MassHealth premium assistance.

MA PFML. Massachusetts PFML provides up to 12 weeks family / 20 weeks medical (26 combined) leave, funded by a payroll contribution (0.88% of wages in 2026 for 25+ headcount employers; employers under 25 are exempt from the employer share).

Medicaid expansion. Massachusetts expanded Medicaid (MassHealth); combined with ConnectorCare, low-wage caregivers have broad subsidized options.

Federal
ALE threshold & counting caregivers. The ACA employer mandate applies to Applicable Large Employers (ALEs) with 50+ full-time equivalent employees (30+ hrs/week or 130 hrs/month). Home care agencies with variable-hour caregivers can use the IRS look-back measurement method (3-12 month measurement period plus a stability period) to determine which caregivers must be treated as full-time and offered coverage.

2026 employer mandate penalties. For 2026, the Section 4980H(a) penalty (no offer of minimum essential coverage to 95% of full-time staff) is $3,340 per full-time employee minus the first 30; the 4980H(b) penalty (coverage unaffordable or not minimum value) is $5,010 per full-time employee who gets subsidized exchange coverage (Rev. Proc. 2025-26).

2026 affordability percentage. Coverage is affordable in 2026 if the employee's self-only contribution does not exceed 9.96% of household income (up from 9.02% in 2025), per Rev. Proc. 2025-25. Employers may use the W-2, rate-of-pay, or federal poverty line safe harbors in place of household income.

2026 FPL safe harbor. A 2026 plan automatically satisfies the federal poverty line affordability safe harbor if the lowest-cost self-only contribution is no more than $129.89/month ($15,650 mainland FPL x 9.96% / 12). Alaska and Hawaii use higher FPL figures (about $162.26 and $149.31/month respectively).

1095-C deadlines (2025 forms filed in 2026). ALEs must furnish Forms 1095-C to employees by March 2, 2026, or use the alternative method under the Paperwork Burden Reduction Act: post a clear website notice and furnish a copy within 30 days of request. E-filing of Forms 1094-C/1095-C with the IRS is due March 31, 2026, and e-filing is mandatory for employers filing 10 or more returns.

ICHRA as a compliance option. An Individual Coverage HRA (ICHRA) lets agencies reimburse caregivers' individual-market premiums tax-free and counts as an offer of coverage under 4980H. An ICHRA is affordable if the employee's cost for the lowest-cost self-only silver plan, minus the HRA allowance, stays within the 9.96% affordability threshold; employee classes (e.g., field caregivers vs. office staff) can receive different allowances.

Enhanced premium tax credits expired 12/31/2025. The ARPA/IRA enhanced premium tax credits expired December 31, 2025, restoring the 400% FPL subsidy cliff. KFF estimates average subsidized marketplace premium payments more than doubled (about +114%) for 2026, making employer-sponsored coverage and ICHRAs more attractive to caregivers - and increasing the chance that full-time employees seek subsidized exchange coverage that triggers 4980H penalties for non-offering agencies.
