Massachusetts ACA Calculator: Estimate Your Health Insurance Subsidy

Use the Massachusetts ACA calculator to estimate your Health Connector subsidy. Covers ConnectorCare income limits, 2026 FPL tables, and how to apply.

If you live in Massachusetts and need help paying for health insurance, you have access to one of the most generous subsidy programs in the country. The Massachusetts Health Connector offers both federal premium tax credits and a state-funded program called ConnectorCare, which together can reduce your monthly premium to as little as $0. This guide walks you through how to estimate your subsidy, what income limits apply in 2026, and exactly how to apply.

What Is the Massachusetts ACA Calculator?

The Massachusetts Health Connector has a built-in "Get an Estimate" tool at MAhealthconnector.org that lets you enter your household size, income, and zip code to see which plans you qualify for and what they would cost after subsidies. It pulls from both federal premium tax credit rules and Massachusetts-specific ConnectorCare rules simultaneously, so you get a complete picture in one place.

You can also use third-party tools like the KFF Health Insurance Marketplace Calculator or healthinsurance.org's subsidy calculator for a quick estimate before going through the official application.

For a multi-program check that also screens you for MassHealth, SNAP, and other programs at the same time, use the free screener at benefitsusa.org/screener.

Two Types of Subsidies Available in Massachusetts

Massachusetts residents can receive help through two separate but related programs:

Federal Premium Tax Credits (APTCs): These are available to households earning between 138% and 400% of the Federal Poverty Level (FPL) who are not eligible for MassHealth. In 2026, the expanded tax credits that were available through 2025 expired, returning subsidy calculations to the pre-2021 rules. This means households above 400% FPL no longer qualify for federal premium assistance.

ConnectorCare: This is Massachusetts' own state-funded subsidy program that wraps around the federal tax credit to further reduce premiums and cost-sharing. ConnectorCare is available to residents earning up to 500% FPL (though the state budget extended this pilot through 2026, and effective subsidy access is capped closer to 400% FPL due to the federal subsidy cliff). ConnectorCare offers income-based plan types with lower premiums, lower copays, and reduced deductibles compared to standard marketplace plans.

2026 Income Limits for Massachusetts Health Connector Subsidies

Massachusetts uses the 2025 Federal Poverty Level figures to determine eligibility for 2026 plan year coverage. The table below shows the key income thresholds by household size.

2025 FPL Dollar Amounts (Used for 2026 Plan Year)

Household Size100% FPL138% FPL (MassHealth limit)200% FPL300% FPL400% FPL
1 person$15,650$21,597$31,300$46,950$62,600
2 people$21,150$29,187$42,300$63,450$84,600
3 people$26,650$36,777$53,300$79,950$106,600
4 people$32,150$44,367$64,300$96,450$128,600
5 people$37,650$51,957$75,300$112,950$150,600
6 people$43,150$59,547$86,300$129,450$172,600

To use this table: find your household size, then look across to find where your annual income falls. Households below 138% FPL typically qualify for MassHealth (Massachusetts Medicaid) rather than marketplace plans. Households between 138% and 400% FPL qualify for premium tax credits. ConnectorCare's additional state subsidies are available up to 500% FPL, though the effective benefit diminishes above 400% FPL in 2026.

ConnectorCare Monthly Premiums in 2026

ConnectorCare groups enrollees into plan types based on income. Here is an overview of what you can expect to pay monthly in 2026:

Income RangeConnectorCare Plan TypeEstimated Monthly Premium
Up to 150% FPLType 1$0
150% to 200% FPLType 2Low (typically under $50)
200% to 250% FPLType 3AModerate
250% to 300% FPLType 3BModerate
300% to 400% FPLType 3CUp to approximately $235

These amounts reflect combined federal and state subsidies. Massachusetts allocated an additional $250 million in the 2026 state budget specifically to hold premiums steady for ConnectorCare members below 400% FPL, partly offsetting the federal enhanced credit expiration.

Who Qualifies for Massachusetts Health Connector Plans?

To enroll in a Health Connector plan and receive subsidies, you must:

  • Live in Massachusetts
  • Be a U.S. citizen or qualified immigration status holder
  • Not have access to affordable coverage through an employer (where "affordable" means your share of the premium is no more than a set percentage of your income)
  • Not be enrolled in Medicare
  • Have income above 138% FPL (below that, you likely qualify for MassHealth instead)

If you fall below 138% FPL, run the free screener at benefitsusa.org/screener to check MassHealth eligibility alongside marketplace options.

How to Use the Massachusetts ACA Calculator: Step by Step

Step 1: Gather Your Information

Before you start, have the following ready:

  • Your estimated annual household income for the coverage year
  • The number of people in your tax household (everyone you claim on your federal return)
  • Your zip code
  • Social Security numbers for all household members
  • Immigration documents if applicable
  • Information about any employer-sponsored health coverage available to you

Step 2: Go to the Health Connector Website

Navigate to MAhealthconnector.org. Click "Get Started" or "Get an Estimate" to begin without creating an account. This preview mode lets you enter basic information to see estimated plan prices and subsidy amounts before committing to a full application.

Step 3: Enter Your Household Details

Input your zip code, household size, and income. The calculator will display plans available in your area along with the estimated monthly premium after your subsidy is applied. You can see both ConnectorCare plans and standard marketplace plans side by side.

Step 4: Compare Plans

Plans are organized by metal tier: Bronze, Silver, Gold, and Catastrophic (for those under 30). ConnectorCare plans are typically based on Silver-level coverage with added state cost-sharing reductions. Look at both the monthly premium and the out-of-pocket costs like deductibles and copays when comparing.

Step 5: Create an Account and Apply

Once you find a plan you like, create a free account on the Health Connector site to submit your full application. You will need to verify your income with documents like pay stubs, a tax return, or a letter from your employer.

Step 6: Enroll

After your eligibility is confirmed, select your plan and confirm enrollment. If you enroll by the 23rd of the month, your coverage typically starts the 1st of the following month.

When Can You Apply?

Open Enrollment: Massachusetts runs its annual open enrollment period from November through late January. For 2026 plan year coverage, the key deadlines were December 23, 2025 for January 1 coverage and January 23, 2026 for February 1 coverage.

Special Enrollment Periods: Outside open enrollment, you can apply if you experience a qualifying life event such as losing job-based coverage, getting married or divorced, having a baby, moving to Massachusetts, or turning 26 and aging off a parent's plan. You generally have 60 days from the event to enroll.

MassHealth: MassHealth (Medicaid) has no enrollment window and accepts applications year-round.

What Happens if Your Income Changes?

Report income changes to the Health Connector as soon as they happen. Your subsidy amount adjusts based on your current income. If you underestimate your income and receive a larger subsidy than you are entitled to, you may owe the difference back when you file your taxes. If you overestimate, you could receive a refund.

For ConnectorCare, the Health Connector does annual redeterminations and will notify you when your renewal is due.

Getting Help with Your Application

If you need personal assistance, Massachusetts has a network of free enrollment assisters across the state. These are trained and certified professionals who can walk you through the application in person, over the phone, or virtually. Find one near you at the Health Connector's website or by calling 1-877-MA-ENROLL (1-877-623-6765).

You can also contact:

  • Health Care For All's HelpLine: 1-800-272-4232
  • Local community health centers
  • A licensed insurance broker (free to use, paid by the insurer)

Massachusetts vs. Federal-Only Marketplace States

Massachusetts operates its own state-based marketplace, giving residents a distinct advantage over those in states that use the federal HealthCare.gov platform. Key differences:

FeatureMassachusetts Health ConnectorFederal Marketplace (HealthCare.gov)
State subsidy (ConnectorCare)Yes, up to 500% FPLNo
$0 premium plansAvailable up to 150% FPLDepends on state
Year-round MassHealth enrollmentYesVaries
Individual mandateYes (state penalty)No federal penalty
Enrollment assistance networkExtensive statewideVaries

Massachusetts also has its own individual mandate, separate from the federal one that was eliminated in 2019. Residents who do not have qualifying coverage may face a state tax penalty.

Frequently Asked Questions

What is the income limit for the Massachusetts Health Connector subsidy in 2026?

For 2026, federal premium tax credits are available to households earning between 138% and 400% of the Federal Poverty Level. That is roughly $21,597 to $62,600 for a single person, or $29,187 to $84,600 for a household of two. ConnectorCare's state subsidies extend to 500% FPL, though the full benefit package is most robust below 400% FPL due to the federal credit expiration for higher incomes.

How do I calculate my ACA subsidy in Massachusetts?

Go to MAhealthconnector.org and use the "Get an Estimate" tool. Enter your household size, zip code, and estimated annual income. The tool will show you available plans and what you would pay after your federal premium tax credit and any ConnectorCare state subsidy. You can also use the KFF subsidy calculator for a quick estimate.

What is ConnectorCare?

ConnectorCare is a Massachusetts-specific health insurance program that layers state subsidies on top of federal ACA premium tax credits. It offers income-based plan types with lower monthly premiums and reduced cost-sharing (deductibles, copays) compared to standard marketplace plans. ConnectorCare is only available to residents who also qualify for federal premium tax credits.

Is ConnectorCare the same as MassHealth?

No. MassHealth is Massachusetts Medicaid and is for households generally below 138% FPL. ConnectorCare is for households above that threshold who shop through the Health Connector marketplace. They are separate programs, though both are administered at the state level.

What happens if my income is below 100% FPL?

If you are a U.S. citizen or long-term immigration status holder with income below 100% FPL, you likely qualify for MassHealth at no cost. Apply at MAhealthconnector.org, which screens for both MassHealth and marketplace plans at once.

Can I apply for the Health Connector outside of open enrollment?

Only if you have a qualifying life event such as losing other coverage, getting married, having a baby, or moving to Massachusetts. You have 60 days from the event to enroll. MassHealth has open enrollment year-round regardless of life events.

Will I owe money back if I get too large a subsidy?

Yes. Premium tax credits are based on your estimated income. If your actual income at year-end is higher than what you estimated, you may need to repay part of the subsidy when you file your federal taxes. The repayment caps vary by income level. Keeping your income estimate current throughout the year reduces this risk.

Does Massachusetts have its own health insurance penalty?

Yes. Massachusetts reinstated its state individual mandate after the federal penalty went to $0 in 2019. If you go without qualifying health coverage for more than 63 consecutive days in a calendar year, you may owe a penalty on your Massachusetts state tax return. The penalty amount depends on your income and the cost of available coverage options.
