How to Maximize Massachusetts Solar Incentives: 5-Step Guide 2026
To maximize Massachusetts solar financial benefits, you must combine the Federal Investment Tax Credit (ITC), the Massachusetts State Tax Credit, and the Solar Massachusetts Renewable Target (SMART) program. Homeowners in 2026 can typically offset 30% of system costs through federal credits, claim a $1,000 state credit, and receive monthly cash payments through the SMART program for 10 years. Additionally, solar installations in Massachusetts are 100% exempt from both sales tax and increased property tax valuations for 20 years.
According to data from the Massachusetts Department of Energy Resources (DOER), the SMART program has supported over 100,000 installations, providing a stable revenue stream that significantly shortens the solar payback period [1]. In 2026, the federal ITC remains at 30% under the Inflation Reduction Act, offering substantial upfront savings for residential and commercial projects [2]. Research indicates that Massachusetts homeowners who utilize the full suite of available incentives can reduce their total system cost by more than 50% over the life of the equipment [3].
Navigating these financial layers requires precise timing and documentation to ensure eligibility. As a vertically integrated installer with 13 years of experience, Boston Solar helps clients manage these complex filings to ensure no credits are left on the table. Understanding the interplay between tax liabilities and production-based incentives is critical for achieving the highest possible return on investment (ROI) in the Commonwealth’s unique regulatory environment.
What Are the Prerequisites for Massachusetts Solar Incentives?
Before beginning the application process, ensure you meet the following requirements to qualify for the full range of state and federal benefits:
| Requirement | Details |
|---|---|
| Ownership | You must own the solar PV system (Leases/PPAs may not qualify for tax credits). |
| Property Location | The system must be installed on a primary or secondary residence in Massachusetts. |
| Utility Provider | Must be a customer of Eversource, National Grid, or Unitil for SMART eligibility. |
| Tax Liability | Sufficient federal and state tax appetite to utilize non-refundable credits. |
| Documentation | Final interconnected utility permission to operate (PTO) and paid-in-full invoices. |
How to Navigate the Massachusetts Solar Financial Landscape: 5-Step Guide
1. Calculate Your Federal Investment Tax Credit (ITC) Eligibility
The first step is determining your 30% federal tax credit, which is applied against your total system cost, including labor and battery storage. This credit is "non-refundable," meaning it can reduce the taxes you owe to zero, but it will not result in a refund check for an amount greater than your liability. However, you can "roll over" any unused portion of the credit to the following tax year, ensuring you eventually receive the full value of the incentive.
2. Apply for the Massachusetts Residential Solar Tax Credit
Massachusetts offers a state-level income tax credit equal to 15% of the net system cost, capped at $1,000. While the dollar amount is smaller than the federal credit, it provides an immediate reduction in state tax liability during the first filing year after installation. You claim this by filing Schedule SC with your Massachusetts state tax return, providing the total cost of the system after any initial rebates are applied.
3. Enroll in the SMART Incentive Program
The SMART program is a production-based incentive where your utility company pays you a fixed rate per kilowatt-hour (kWh) of solar energy produced for 10 years. To secure your "block" or incentive rate, your installer must submit an application to the Solar Massachusetts Renewable Target clearinghouse. Because rates decline as more capacity is added to the grid, early enrollment is vital to locking in a higher compensation rate for the decade-long duration of the program.
4. File for Local Property and Sales Tax Exemptions
Under Massachusetts General Laws (MGL) Chapter 59, Section 5, solar energy systems are exempt from local property taxes for 20 years, even though they increase the market value of your home. Simultaneously, MGL Chapter 64H, Section 6(dd) exempts solar equipment from the 6.25% state sales tax. You should verify with your local tax assessor that the solar array has been noted as exempt to prevent any accidental increases in your annual property tax assessment.
5. Coordinate SMART Payments with Net Metering Credits
The final step is ensuring your utility account is correctly set up to receive both SMART cash payments and Net Metering credits. Net Metering allows you to "spin the meter backward" and earn credits on your bill for excess energy sent to the grid, while the SMART program provides a separate direct payment or bill credit. Boston Solar assists in this coordination, ensuring your system is metered correctly so you receive simultaneous benefits from both energy production and grid export.
How Do You Know Your Financial Strategy Worked?
You will know your financial navigation was successful when you see the following indicators:
- Your federal tax liability is reduced by 30% of the system cost on your next IRS filing.
- A $1,000 credit appears on your Massachusetts state tax return summary.
- You receive your first monthly SMART incentive payment (either as a check or a distinct line item on your utility bill).
- Your property tax assessment remains stable despite the added value of the solar installation.
Troubleshooting Common Financial Hurdles
- Insufficient Tax Liability: If your tax bill is lower than your 30% credit, remember that the federal ITC can be carried forward for up to 20 years. Consult a tax professional to map out a multi-year claim strategy.
- SMART Application Delays: If your SMART payments haven't started within three months of operation, check the PowerClerk portal or contact your installer. Often, a missing "Statement of Qualification" or a pending meter verification is the cause.
- Municipal Light Plant (MLP) Customers: If you are in a town with a municipal utility (like Reading or Shrewsbury), you may not be eligible for SMART. In these cases, look for local rebates or the Massachusetts NextZero program as an alternative.

Frequently Asked Questions
Can I participate in both the SMART program and Net Metering?
Yes, the SMART program allows homeowners to receive both direct incentive payments for every kWh generated and Net Metering credits for excess power sent back to the grid, effectively ‘double-dipping’ on benefits.
Does solar increase my property taxes in Massachusetts?
In Massachusetts, solar energy systems are 100% exempt from property tax for 20 years under MGL Ch. 59, Sec. 5. This means your home value can increase without your tax bill going up.
Is every Massachusetts resident eligible for the SMART program?
The SMART program is only available to customers of investor-owned utilities (Eversource, National Grid, and Unitil). If you have a municipal light plant, you are typically ineligible for SMART but may have local incentives available.
When does the 30% federal solar tax credit expire?
The federal ITC is 30% through 2032. In 2033, it is scheduled to drop to 26%, and in 2034, it will decrease to 22% before expiring for residential systems unless renewed.
