The Massachusetts health care reform law mandates and penalties still in force today require nearly every adult resident to carry health insurance that meets state standards, with a monthly tax penalty for going without. Unlike the federal individual mandate, which was zeroed out in 2019, the Massachusetts version has teeth: penalties range from $25 to $187 per uncovered month depending on your income, collected through your state tax refund.
Who the Mandate Applies To
The individual mandate lives in Massachusetts General Laws Chapter 111M.1General Court of Massachusetts. Massachusetts General Laws Chapter 111M – Individual Health Coverage Every adult filing a Massachusetts income tax return has to report, month by month, whether they had creditable coverage during the year. That reporting happens on Schedule HC, which is filed with your state return.
Whether the mandate reaches you depends on whether affordable coverage was available. Residents with household income below 150% of the federal poverty level are generally not penalized, because no premium is considered affordable at that level. For everyone else, the Health Connector publishes an annual affordability schedule setting the maximum monthly premium a person at each income bracket could reasonably be expected to pay.2Massachusetts Health Connector. Affordability Schedule The share of income treated as affordable runs from 0% at the bottom of the scale to 8% for people above 400% FPL. If a qualifying plan was available to you at or below that threshold and you didn’t buy it, you may owe the penalty.
What Counts as Creditable Coverage
Having any health plan is not enough. The plan has to meet the state’s Minimum Creditable Coverage (MCC) rules, which the Health Connector updates each year and which cap what a plan can charge you before it starts paying and what you can spend out of pocket over the year.
For 2026, the MCC limits are:3Massachusetts Health Connector. Guidance Regarding Minimum Creditable Coverage Regulations for Calendar Year 2026
- Individual deductible no higher than $3,200
- Family deductible no higher than $6,400
- Separate prescription drug deductible, if the plan has one, no higher than $400 individual or $800 family
- Maximum out-of-pocket of $10,150 self-only or $20,300 family
A high-deductible plan purchased outside the Health Connector marketplace may exceed these limits. If it does, it doesn’t count as creditable coverage, and you can be penalized even though you technically have insurance. Insurers that offer MCC-qualifying plans send you Form MA 1099-HC by January 31, and you use it when filing your state return to prove compliance.
How the Penalty Is Calculated and Collected
The penalty is assessed monthly, one month at a time, for each month you lacked creditable coverage. A gap of 63 days or fewer doesn’t count, so a short break between jobs usually costs nothing.4General Court of Massachusetts. Massachusetts General Laws Chapter 111M Section 2 Longer gaps trigger the penalty.
By statute, the annual penalty cannot exceed half the cost of the cheapest qualifying plan that was available to you through the Health Connector the prior year. The Department of Revenue translates that cap into a penalty table on Schedule HC. For tax year 2025, monthly amounts run from $25 to $187 based on income and family size.5Mass.gov. 2025 Massachusetts Schedule HC Instructions A single filer earning roughly $23,000 to $30,000 owes $25 per uncovered month; a single filer above $60,000 could owe $187 per month.
Collection runs through the tax system. If you’re due a refund, the Department of Revenue takes the penalty out first and sends you the balance. If your refund doesn’t cover the full amount, the state bills you for the rest and can use its ordinary tax-collection tools to recover it.
Appealing the Penalty
If you couldn’t afford coverage or faced circumstances that made it impossible to enroll, you can appeal. Start on your tax return: fill in the appeal oval on Schedule HC, and leave the penalty amount blank. The Department of Revenue holds off on assessing the penalty while the appeal is pending and shares your return with the Health Connector.6Mass.gov. Learn How to Appeal the Health Care Penalty
The Health Connector then sends you a letter asking for your written grounds and supporting documents. Do not send hardship documents with your original tax return; wait for the letter and respond within the deadline it gives you, or the appeal is dismissed automatically. The Connector may also require a hearing. You get one appeal per year. If it’s denied or dismissed, the Department of Revenue bills you.
Separately, residents whose income falls outside federal premium-tax-credit eligibility, generally below 100% or above 400% of the federal poverty level, can apply to the Health Connector for a hardship exemption. Approval lets them buy a lower-cost Catastrophic plan in place of a standard MCC plan.7Massachusetts Health Connector. Hardship Exemption and How to Apply
ConnectorCare Subsidies
The way most lower- and middle-income residents meet the mandate affordably is ConnectorCare, which layers state subsidies on top of federal Advance Premium Tax Credits to produce lower premiums and cost-sharing than a standard marketplace plan.8Massachusetts Health Connector. 2026 Consumer Guide to Subsidies
For 2026, ConnectorCare is open to households with income between 100% and 400% of the federal poverty level, with premiums tied to income:9Massachusetts Health Connector. Can You Get Help Paying for Health Insurance Through the Health Connector
- Plan Type 2A (100–150% FPL): $0 per month
- Plan Type 2B (150–200% FPL): starting at $53
- Plan Type 3A (200–250% FPL): starting at $103
- Plan Type 3B (250–300% FPL): starting at $152
- Plan Type 3C (300–400% FPL): starting at $235
For a single person in 2026, 100% FPL is $15,650 and 400% is $62,600; a household of four qualifies with income between $32,150 and $128,600. Eligibility requires Massachusetts residency, income verification, and no access to other subsidized coverage such as MassHealth or qualifying employer-sponsored insurance. ConnectorCare plans automatically meet MCC standards, so enrolling satisfies the mandate.
What Employers Owe
The original 2006 employer contribution requirement and its Fair Share Contribution penalty under Chapter 151F were repealed in 2013 and 2014 as the ACA’s employer-responsibility rules took effect.10Massachusetts Health Connector. Repeal of Employer-Related Regulations Massachusetts employers today instead pay the Employer Medical Assistance Contribution (EMAC), which funds state health programs. EMAC is calculated on the first $15,000 of each employee’s annual wages, with the rate phasing in based on how long the employer has been paying into the unemployment system:11Mass.gov. Employer Medical Assistance Contribution (EMAC)
- Years 1–3: exempt
- Year 4: 0.12%
- Year 5: 0.24%
- Year 6 and beyond: 0.34%
Employers with fewer than six employees in a quarter are also exempt. EMAC is reported through the quarterly wage filings employers already submit to the Department of Unemployment Assistance, with no separate form. Employers who skip those filings will have their EMAC estimated for them, and the estimate rarely favors the employer.
Why the Mandate Still Bites
Massachusetts never followed Congress in eliminating the mandate penalty, and revenue from the penalty helps fund the state’s affordability programs. The results the state points to are the coverage numbers: 97.9% of residents had coverage in the 2025 Massachusetts Health Insurance Survey, an uninsured rate of 2.1% compared with 8.2% nationally.12Center for Health Information and Analysis. Findings From the 2025 Massachusetts Health Insurance Survey For a resident, the practical takeaway is straightforward. Check that your plan meets the MCC limits, keep your Form 1099-HC for tax season, and if you have a coverage gap longer than 63 days, either apply for ConnectorCare or be ready to appeal on Schedule HC.
