Mass Save Income Limits 2026: What You Qualify For at Every Level
Mass Save's income-qualified programs can cover 100% of insulation and up to $16,000 for heat pumps — but the income thresholds confuse a lot of people. Here's the plain-English breakdown of who qualifies, what you get, and how to apply.
Key Takeaways
- Mass Save uses Area Median Income (AMI) — not a flat number — so limits vary by county and household size
- At 60% AMI: free insulation, up to $16,000 for heat pumps, and free appliance replacements
- At 80% AMI: enhanced rebates above standard — 90–100% insulation coverage, higher heat pump amounts
- Already enrolled in SNAP, MassHealth, or LIHEAP? You auto-qualify — no income docs needed
"Do I qualify for the income-based Mass Save programs?"
It's one of the most-searched questions about Massachusetts energy rebates — and one of the hardest to answer, because Mass Save doesn't use a simple dollar cutoff. Instead, they use something called Area Median Income (AMI), which changes based on where you live and how many people are in your household.
The difference between qualifying and not qualifying can be worth $5,000–$16,000 in additional rebates. So it's worth understanding exactly where you stand.
This guide breaks down the income limits for every tier, what you actually get at each level, and the fastest ways to prove you qualify.
How Mass Save Income Qualification Works
Mass Save has three tiers of rebates. Think of them as bronze, silver, and gold:
- Standard (any income): Everyone with a Massachusetts utility account qualifies. This includes 75% off insulation, $1,250–$10,000 for heat pumps, free smart thermostats, and 0% financing.
- Enhanced (80% AMI): If your household income is at or below 80% of the Area Median Income for your county. Higher rebate amounts across the board.
- Income-Qualified (60% AMI): If your household income is at or below 60% AMI. Maximum rebates — many upgrades are fully covered at no cost.
What Is Area Median Income?
AMI is the midpoint income for your geographic area. If the median household income in your county is $100,000, then 80% AMI is $80,000 and 60% AMI is $60,000. The actual numbers are set by HUD (the U.S. Department of Housing and Urban Development) and adjusted annually.
The reason Mass Save uses AMI instead of a flat number: cost of living varies across Massachusetts. A household earning $65,000 in Western MA has different purchasing power than one earning $65,000 in Greater Boston. AMI accounts for this.
2026 Income Limits by County and Household Size
Here are the approximate AMI thresholds for two of the most common Massachusetts counties. Your county may differ — contact your utility for exact numbers.
2026 Mass Save Income Limits (Approximate)
| Household Size | 60% AMI (Full Benefits) | 80% AMI (Enhanced) | ||
|---|---|---|---|---|
| Suffolk Co. | Worcester Co. | Suffolk Co. | Worcester Co. | |
| 1 person | $44,580 | $40,440 | $59,550 | $53,920 |
| 2 people | $50,940 | $46,200 | $68,000 | $61,600 |
| 3 people | $57,300 | $51,960 | $76,500 | $69,280 |
| 4 people | $63,750 | $57,720 | $85,050 | $77,040 |
| 5 people | $68,850 | $62,340 | $91,900 | $83,200 |
Bigger Household = Higher Limit
A family of 5 in Suffolk County qualifies at 80% AMI with household income up to $91,900. Many families who assume they don't qualify are surprised when they check the limits for their actual household size.

What You Get at Each Income Level
This is where the math gets interesting. The gap between standard and income-qualified rebates is significant — especially for heat pumps and insulation.
Mass Save Rebates by Income Tier
| Benefit | Standard (Any Income) | 80% AMI | 60% AMI |
|---|---|---|---|
| Insulation | 75% covered | 90–100% covered | 100% covered |
| Heat Pumps (oil/propane) | Up to $10,000 | Up to $12,000 | Up to $16,000 |
| Heat Pumps (natural gas) | $1,250–$3,500 | Up to $6,000 | Up to $10,000 |
| Heat Pump Water Heater | $750–$1,250 | Up to $2,000 | Up to $2,500 |
| Appliance Rebates | Standard amounts | Enhanced amounts | Free replacements possible |
| Home Energy Assessment | Free | Free + extra services | Free + extra services |
| HEAT Loan (0% interest) | Up to $50,000 | Up to $50,000 | May not need (work is free) |
Real Example: Heat Pump + Insulation for a 60% AMI Household
* $1,400 for $23,500 worth of upgrades. The insulation is free. The remaining $1,400 for the heat pump can be covered by the HEAT Loan at 0% interest.
Compare that to the standard tier: the same household without income qualification would pay roughly $1,375 for insulation (75% covered) and $8,000 for the heat pump ($10,000 rebate) — about $9,375 total. Still good, but the income-qualified savings are $7,975 more.
How to Prove You Qualify
Income verification through Mass Save is straightforward. You don't need a CPA or a stack of paperwork. Here's what they accept:
Tax Returns
Most recent federal tax return (1040). This is the most common method. Your adjusted gross income (AGI) is the number they look at.
Pay Stubs
Recent pay stubs showing gross income. Useful if your current income is lower than last year's tax return (job change, reduced hours, etc.).
Benefit Statements
Social Security, disability, pension, or unemployment benefit statements. These count as income documentation for AMI calculations.
Program Enrollment (Auto-Qualify)
Enrollment in SNAP, MassHealth, LIHEAP, fuel assistance, or other income-based programs automatically qualifies you. No additional income docs needed.
Programs That Automatically Qualify You
Already enrolled in one of these programs? You're in. No income documents required — just provide your enrollment confirmation.
- SNAP (Supplemental Nutrition Assistance Program / food stamps)
- MassHealth (Medicaid)
- LIHEAP (Low Income Home Energy Assistance Program)
- Fuel Assistance (state heating assistance)
- SSI (Supplemental Security Income)
- TANF (Transitional Aid to Families with Dependent Children)
- WIC (Women, Infants, and Children)
- Veterans' Service Benefits
This is the fastest path to income-qualified status. If you receive any of these benefits, mention it when you schedule your Home Energy Assessment. The utility can verify enrollment directly in most cases.
Community Action Agencies Can Help
Not sure if you qualify? Your local Community Action Agency (CAA) can help determine eligibility and walk you through the application. They handle income-qualified energy programs daily and know the process inside out. Find your local CAA.
Don't Qualify? Standard Rebates Are Still Excellent
Here's something important: even if you don't meet the income thresholds, Mass Save's standard rebates are among the best in the country. You still get:
- 75% off insulation — a $5,500 project costs you about $1,375
- Up to $10,000 for heat pumps — when switching from oil, propane, or electric resistance
- Free smart thermostat — delivered to your door or installed at the assessment
- 0% HEAT Loan — up to $50,000 for 7 years with zero interest
- $750–$1,250 for heat pump water heaters
- Rebates for windows, appliances, and weatherization
Plus, you can stack every Mass Save rebate with the federal Energy Efficient Home Improvement Credit (25C) for an additional 30% off your remaining out-of-pocket costs. The standard program alone can save a typical household $10,000–$15,000 on a major energy upgrade.
What If Your Income Changed Recently?
Mass Save evaluates your current household income, not just your most recent tax return. This matters if:
- You recently lost a job or had hours reduced
- A household earner retired
- You went through a divorce or separation
- You started receiving disability benefits
In these cases, provide recent pay stubs or a letter from your employer showing your current income. Your utility will work with you to determine eligibility based on your actual situation, not just last year's tax return.
The Bottom Line
Mass Save's income-qualified programs can save you $5,000 to $16,000 more than the standard rebates — and for households at 60% AMI, many upgrades are completely free. But even the standard tier is worth pursuing, with 75% off insulation and five-figure heat pump rebates available to everyone.
The smartest first step is the same regardless of income: schedule your free Home Energy Assessment. The assessor can help determine your income eligibility on the spot and explain exactly what you'd qualify for. There's no cost and no obligation.
If you're near the income threshold, it's especially worth checking. AMI limits increase with household size, vary by county, and are updated annually. You might qualify and not know it.

Frequently Asked Questions
What are the Mass Save income limits for 2026?
Mass Save uses Area Median Income (AMI) thresholds, which vary by county. At 60% AMI, a household of 4 in Suffolk County qualifies at about $63,750. At 80% AMI, the threshold rises to about $85,050. These numbers change annually — your utility can confirm the current limits for your area.
How do I prove my income for Mass Save?
You can provide recent tax returns, pay stubs, Social Security benefit statements, or a letter from your employer. Some utilities also accept enrollment in other income-based programs (SNAP, MassHealth, LIHEAP, fuel assistance) as automatic proof of eligibility.
Can I qualify based on household size, not just income?
Yes. AMI limits increase with household size. A single person has a lower threshold than a family of four. This means some families who earn above the "per person" limit still qualify when you account for all household members.
What if I'm just above the income limit?
You still qualify for all standard Mass Save rebates, which are substantial — 75% off insulation, $1,250–$10,000 for heat pumps, free smart thermostats, and 0% HEAT Loan financing. The income-qualified tier adds enhanced amounts, but the standard program is already very generous.
Do I need to reapply each year?
Income qualification applies per project, not annually. Once approved for an income-qualified rebate, that project's pricing is locked in. If your income changes, future projects would be evaluated based on your income at that time.
Can renters qualify for income-based Mass Save rebates?
Yes. Renters can receive income-qualified benefits, but the property owner must authorize the installation work. Many landlords agree because the upgrades are free or heavily subsidized and increase property value. Your utility can help coordinate with your landlord.
