What Is the Massachusetts Senior Circuit Breaker Tax Credit?
If you’re 65 or older and live in Massachusetts, the Senior Circuit Breaker Tax Credit could put real money back in your pocket at tax time — whether you own your home or rent it.
It’s a refundable Massachusetts state income tax credit available to homeowners and renters age 65+. The credit is based on how much you paid in real estate taxes (or, for renters, 25% of the rent you paid) compared to a set percentage of your total household income.
Because it’s refundable, you can receive the full credit even if you owe little or no Massachusetts income tax — the state sends you the difference as a refund.
It’s worth being clear about one common mix-up: the Circuit Breaker credit is a separate program from the Clause 41C property tax exemption. Clause 41C is a local-option exemption that varies city by city, while the Circuit Breaker credit is statewide and administered through your state income tax return. More on how the two interact below.
Who Qualifies (Age, Residency, Filing Status)
Eligibility comes down to four basic requirements:
- You must be 65 or older by December 31 of the tax year you’re filing for.
- You must own or rent, and actually live in, the property as your principal Massachusetts residence.
- You cannot be claimed as a dependent on someone else’s tax return.
- Both homeowners and renters are eligible — renters simply use 25% of their annual rent as a stand-in for property taxes paid.
2025 Tax Year Income & Assessed Value Limits (Filed in 2026)
For the 2025 tax year — the return most people are filing in 2026 — the income and property value limits are:
| Filing Status | 2025 Income Limit |
|---|---|
| Single (not head of household) | $75,000 |
| Head of household | $94,000 |
| Married filing jointly | $112,000 |
Homeowners also need to check the assessed value of their home. For 2025, the assessed value of your home (before any residential exemption, but after abatements) cannot exceed $1,298,000.
Keep in mind these thresholds adjust for inflation every year. The figures above apply specifically to the 2025 tax year. If you’re filing for the 2026 tax year later on, check Mass.gov for the updated Schedule CB instructions before you file — don’t assume the same numbers carry over automatically.
How Much Is the Credit Worth?
For the 2025 tax year, the maximum credit is $2,820.
The credit is calculated as the amount your real estate taxes (or 25% of rent paid) exceed a set percentage of your total income. In plain terms: the state looks at how much of your income is going toward housing costs, and if that share is unusually high relative to your income, the difference — up to the annual cap — comes back to you as a credit.
A Simple Worked Example
Let’s walk through two hypothetical filers to see how this plays out:
Example 1 — Homeowner: A single 68-year-old with $40,000 in annual income pays $4,800 in real estate taxes on her home. Because her property tax burden is high relative to her income, she qualifies for a substantial credit — potentially close to the maximum, depending on the exact formula applied that year.
Example 2 — Renter: A 70-year-old renter with $35,000 in annual income pays $1,500/month in rent, or $18,000/year. Using the 25%-of-rent rule, $4,500 is treated as his “property tax” for purposes of the calculation — likely also producing a meaningful credit.
The exact dollar amount depends on the specific income-percentage formula in that year’s Schedule CB instructions, so these examples are meant to illustrate the mechanics, not to predict your exact refund. Schedule CB itself will walk you through the actual calculation line by line.
Homeowners vs. Renters — How the Calculation Differs
| Homeowners | Renters | |
|---|---|---|
| What counts as “property tax” | Actual real estate taxes paid on the home | 25% of total rent paid during the year |
| Assessed value limit applies? | Yes — $1,298,000 cap for 2025 | No assessed value test |
| Income limit applies? | Yes, by filing status | Yes, same limits by filing status |
How to Claim It (Schedule CB)
To claim the credit, file Massachusetts Form 1 (or Form 1-NR/PY) along with Schedule CB.
Here’s something a lot of people don’t realize: you can file solely to claim this refund even if your income is low enough that you wouldn’t otherwise be required to file a Massachusetts tax return at all. Skipping your return because “I don’t owe anything” could mean leaving hundreds or thousands of dollars unclaimed.
If you’d rather not tackle the form alone, free help is available. AARP Foundation Tax-Aide and VITA (Volunteer Income Tax Assistance) sites across Massachusetts help seniors and low-to-moderate income filers complete returns like this one every tax season at no cost.
Circuit Breaker vs. Clause 41C Property Tax Exemption — Can You Get Both?
Many Massachusetts seniors assume they have to pick one program or the other. In most cases, that’s not true.
- Clause 41C is a local-option property tax exemption applied at the city or town level. Each municipality decides whether to offer it, and the specific income/asset limits vary by location.
- Circuit Breaker is a state income tax credit, claimed on your state return, and is largely independent of whatever your town does with Clause 41C.
Because these are two different systems administered by two different offices, it’s worth checking with your local assessor’s office about Clause 41C in addition to filing Schedule CB for the Circuit Breaker credit. You may be eligible for meaningful savings from both.
Frequently Asked Questions
Do I need to itemize deductions to claim this credit?
No. The Circuit Breaker credit is claimed through Schedule CB on your Massachusetts return and is separate from federal itemizing decisions.
What if I moved during the tax year?
You generally need to have occupied the property as your principal residence for the relevant portion of the year; check the Schedule CB instructions for how partial-year residency and multiple residences are handled.
Is the credit taxable income?
No — it’s a state tax credit/refund, not taxable income for Massachusetts purposes. Confirm treatment for federal purposes with a tax professional if you’re unsure.
What’s the deadline to file for the credit?
It follows the standard Massachusetts income tax filing deadline (typically mid-April), though you may be able to file later using an extension. Because the credit is only available for the current filing year’s Schedule CB, don’t wait until the last minute.
