Massachusetts has a tax credit for some older residents whose property tax or rent is high compared with their income. It is called the Senior Circuit Breaker. You claim it on Schedule CB with a Massachusetts income tax return. It is a refundable tax credit, not a property-tax grant and not a discount issued by your town.
Bottom Line
If you were at least 65 by December 31, 2025, and owned or rented your main Massachusetts home, check the state’s credit rules. For tax year 2025, the largest possible credit is $2,820. Your income, housing costs, filing status, and other rules determine whether you get a credit and how much. You can claim it even if you owe little or no state income tax, but you must file a return.
Start Here
- Choose the tax year. If you are filing in 2026 for income and housing costs from 2025, use the 2025 rules and forms. The 2026 tax-year limits are not confirmed here.
- Check the two tests. Compare your total Massachusetts income with the 2025 income limit. Then check whether your qualifying housing cost exceeds 10% of that income.
- File Schedule CB. Use the 2025 state tax forms with your Massachusetts income tax return, or get help preparing them.
| Your situation | Next action | Watch for |
|---|---|---|
| You own your main home | Gather property tax paid and eligible water and sewer charges. | 2025 assessed home-value limit and tax abatements. |
| You rent your main home | Gather your full 2025 rent payment record. | State or federal rent subsidy and tax-exempt landlord exclusions. |
| You already filed | Check whether Schedule CB was included; amend if eligible. | The credit’s special three-year claim deadline. |
What the Credit Does
The Massachusetts Department of Revenue (DOR) runs this statewide credit through the income tax system. You do not apply to your town assessor for Schedule CB. It is for residents age 65 and older whose eligible costs exceed one-tenth of qualifying income.
Refundable means the credit may be paid back to you if it is larger than the state income tax you owe. It is not an advance payment on a property-tax bill. DOR explains this difference in its senior tax information. A town tax bill must still be paid or handled with the town while your income tax return is processed.
An official 2025 tax notice sets the $2,820 cap. Earlier amounts do not apply. Do not assume these figures apply when filing 2026 taxes in 2027.
Who May Qualify for Tax Year 2025
You must be a full-year or part-year Massachusetts resident and have owned or rented a Massachusetts home used as your main residence. You, or your spouse on a joint return, must have turned 65 by December 31, 2025. You must use an allowed filing status, and your housing costs must pass the credit’s test.
| Rule | 2025 limit or test |
|---|---|
| Single filer | Total Massachusetts income no more than $75,000 |
| Head of household | Total Massachusetts income no more than $94,000 |
| Married filing jointly | Total Massachusetts income no more than $112,000 |
| Homeowner’s assessed value | No more than $1,298,000 as of January 1, 2025, under the special assessment rules |
| Housing-cost test | Qualifying taxes or 25% of rent must exceed 10% of qualifying income |
| Maximum refundable credit | $2,820, not an automatic payment |
These are annual limits. The DOR filing tips and the 2025 Schedule CB instructions confirm that you must use the correct filing status and the year-specific rules.
Important exclusions: Nonresidents, married-separate filers, and dependents cannot claim it. Renters who receive a federal or state rent subsidy, or rent from a tax-exempt entity, are excluded under DOR rules. Ask DOR about unusual housing.
If you own a two-family home, own more than one acre, share ownership, or hold your home in a trust, your eligible property value and tax expense may need special treatment. Do not treat the full parcel’s tax bill as your own eligible expense without reviewing the Form 1 instructions.
What Counts as Income?
For Schedule CB, “total Massachusetts income” is not simply the taxable amount shown on your federal return. DOR starts with Massachusetts adjusted gross income, makes stated additions and adjustments, and uses the result on Schedule CB. This can include Social Security benefits before Medicare premiums and some pension or retirement income not taxed by Massachusetts.
A person who owes no Massachusetts income tax may still have income counted for this credit. Read the 2025 Schedule CB calculation or have a preparer complete it. Take-home pay is not the test.
On a joint return, the couple’s qualifying income is tested under the joint limit. For a part-year move or a change in marital status, ask which income and housing payments belong on the year’s return. The state’s tax-form guidance provides the correct year and return type.
What Property Tax or Rent Counts?
If you own your home
Use eligible real estate taxes actually paid during calendar year 2025 for your main home, after the adjustments required on Schedule CB. Check payment dates: local fiscal years differ from state income tax years.
If qualifying water and sewer use charges were paid separately rather than included as qualifying debt charges in the tax assessment, the form may permit 50% of those charges. Never count the same charge twice. Local tax exemptions and abatements affect what you can count; the credit is based on eligible net costs, not an unchanged pre-relief bill.
If you rent your home
For renters, the state compares 25% of qualifying rent with 10% of total income. This does not mean renters receive 25% of their rent back. Only the excess, up to the yearly cap, can become a credit.
Keep records of rent actually paid during the year, plus landlord details. Ask DOR if your housing is in a nonprofit building, subsidized, shared with others, or part of a care setting. These facts can change the result.
How to File Schedule CB
- Get the proper return. Use 2025 Form 1 for a full-year resident or the relevant part-year form if appropriate. Add Schedule CB. DOR’s filing options explain online, software, and paper routes.
- Complete all income lines. Include the income items Schedule CB asks for, even when they do not raise your ordinary state tax.
- Complete one housing section. Use the homeowner or renter section that applies to your circumstances. Follow the instructions if you moved during 2025.
- Send the full state return. Schedule CB is not a separate application to the local assessor. Keep a copy of your return and proof of each housing payment.
- Check the refund. Use DOR’s refund-status guidance. A credit may take time to be reviewed; a filing is not a guarantee of payment.
Some people can use MassTaxConnect for free, including eligible full-year residents who have filed a Massachusetts return before. DOR also describes options for some prior-filing part-year residents. A first-time filer should not assume the same online path will work. Check MassTaxConnect eligibility or use approved software, paper forms, or tax help.
Dates: DOR listed April 15, 2026 as the regular deadline for 2025 Massachusetts individual returns, with October 15, 2026 for those with a valid filing extension. If you have not filed, confirm whether an extension applies.
Documents to Gather
| Document | Why it matters |
|---|---|
| 2025 income forms | Social Security statement, pension forms, tax forms, and any other income details for Schedule CB |
| Tax bill and payment proof | Homeowner’s actual 2025 property taxes paid, not just billed |
| Assessment information | Homeowner value as of January 1, 2025, including any needed allocation |
| Water and sewer bills | Eligible charges actually paid, if not already included in the tax assessment |
| Lease and rent receipts | Amount, dates, address, and landlord details for renters |
| Prior state return | Shows filing status and whether Schedule CB was already submitted |
You can use the state’s tax preparation help directory to find Volunteer Income Tax Assistance (VITA), AARP Tax-Aide, or other qualified help. Ask whether the site handles Massachusetts Schedule CB.
If You Forgot the Credit or DOR Says No
Already filed without Schedule CB? DOR tells taxpayers to amend the same tax year’s Massachusetts return, attach Schedule CB, and include proof of tax or rent paid and relevant water and sewer payments. Follow the amended-return instructions. Do not file a second original return for the same year.
Missed a past year? DOR says Schedule CB generally must be completed within three years from the last day to file that year’s return, ignoring filing extensions. This is a credit-specific limit. Do not assume all older years are still open; use the correct prior-year form and ask DOR about your exact deadline.
Received a letter or a smaller credit? Read which income item, rent payment, tax payment, or assessed value DOR questions. Gather supporting records before replying. Do not use an amended return to dispute an audit assessment. For an agency dispute, use the DOR appeal information and follow the dates shown on the actual notice.
If delayed, save your filing confirmation and ask DOR what proof it needs.
How This Differs From Local Property Tax Relief
The Senior Circuit Breaker is statewide and claimed through an income tax return. Local senior exemptions, deferrals, and work-off programs are different. They may require separate applications to a city or town assessor, and some are not offered in every community.
Homeowners can check our Massachusetts property tax guide for those local choices. The state’s local property-tax forms explain assessor applications. A local exemption does not automatically prevent a Schedule CB claim, but it can reduce the property-tax payment counted for this credit. Do not add the advertised maximums of separate programs together.
Our state tax differences guide explains why relief types vary. Our state property-tax directory provides wider context. Your claim must still follow Massachusetts tax forms.
If you rent but cannot use Schedule CB, our Massachusetts housing assistance guide explains other housing help. For other Massachusetts programs, see our Massachusetts senior benefits guide. Use the Schedule CB instructions for your claim.
Common Mistakes and Reality Checks
- Using 2024 or 2026 figures. For a 2025 claim, apply 2025 rules. DOR updates annual limits; the 2026 tax-year values need their own official release.
- Counting only taxable Social Security. Schedule CB may count the full benefit before Medicare deductions.
- Claiming the assessed home’s full tax bill. Actual payment, exemptions, ownership share, and year of payment matter.
- Calling the town for the credit. DOR handles Schedule CB. Your assessor is the right office for property assessment questions and local exemptions.
- Assuming low income guarantees money. You also need eligible housing costs above the threshold.
- Ignoring the subsidy rule. Certain subsidized renters are excluded, even when their rent feels high.

Ask DOR about eligibility
“I am checking Schedule CB for tax year 2025. My housing situation is unusual. Can you tell me which instructions apply and what proof I need?”
Ask the assessor about home value
“I need the assessed value of my main residence as of January 1, 2025, for Schedule CB. Which record should I use?”
Ask a tax-help program
“Do you prepare Massachusetts returns with Schedule CB? I may need to claim a past year. What should I bring?”
Resumen en Español
El crédito Senior Circuit Breaker de Massachusetts es un crédito tributario reembolsable, no una subvención ni una reducción directa de la factura municipal. Para el año fiscal 2025, el crédito máximo es de $2,820, pero depende de sus ingresos y de los impuestos de propiedad o del alquiler que pagó. En general, debe tener 65 años o más al 31 de diciembre de 2025 y presentar una declaración estatal con el Anexo CB (Schedule CB). Hay límites de ingresos y otras exclusiones. Si olvidó pedir el crédito, consulte con el Departamento de Ingresos sobre una declaración enmendada y el plazo de tres años. Guarde sus comprobantes y pida ayuda para preparar los impuestos si la necesita.
Questions and Answers
Is Schedule CB a property tax exemption?
No. It is a refundable Massachusetts income tax credit claimed with a state income tax return. Local exemptions are separate applications to a city or town.
Can a renter claim the Senior Circuit Breaker?
Some renters can. For tax year 2025, 25% of qualifying rent must exceed 10% of qualifying income. Renters with a federal or state rent subsidy, or a tax-exempt landlord, are excluded.
What is the maximum credit for tax year 2025?
The maximum is $2,820 for tax year 2025. It is not an automatic payment; your eligible housing costs and income determine the amount.
Can I get a refund if I owe no state tax?
Possibly. The credit is refundable, but you must qualify and file a Massachusetts return with Schedule CB, even if you would not otherwise have to file.
What if I forgot to file Schedule CB?
You may be able to amend the return for the correct year. DOR generally requires Schedule CB within three years of the original filing deadline, without counting extensions. Check your exact year and instructions with DOR.
