Massachusetts Property Tax 2026: Proposition 2½, Local Rates & Exemptions

How Massachusetts Property Tax Works in 2026

Massachusetts has no statewide property tax. Property is assessed and taxed entirely at the local level by each of the state's 351 cities and towns, under the oversight of the Massachusetts Department of Revenue's Division of Local Services (DLS). Massachusetts runs its fiscal year from July 1 to June 30 — so "FY2026" refers to the tax year running July 1, 2025 through June 30, 2026 — and properties are valued as of January 1, 2025 (the assessment date required by Mass. Gen. Laws c. 59, §38) to set the values and rates used for FY2026 bills. Each community's board of assessors certifies property values, and its select board, city council, or town meeting adopts a tax rate — expressed in dollars per $1,000 of assessed value — sufficient to raise the revenue authorized under state law.

The central constraint on how much revenue any Massachusetts community can raise through property tax is Proposition 2½, a 1980 ballot law codified at Mass. Gen. Laws c. 59, §21C. It limits both how fast a town's total property tax levy can grow year to year (the levy limit) and how large that levy can ever become relative to the town's total property value (the levy ceiling) — two related but distinct caps that are frequently conflated. This guide walks through how Prop 2½ actually works, the state's main relief programs for seniors, veterans, and blind homeowners, how FY2026 rates compare across a sample of cities and towns from Boston to Cape Cod, and a worked example for a home in Worcester.

Local Assessment, the DLS, and How Your Bill Is Calculated

Unlike states that levy a statewide property tax or a uniform statewide assessment ratio, Massachusetts leaves both valuation and rate-setting entirely to local government. The Department of Revenue's Division of Local Services (DLS) doesn't set rates itself — instead, it certifies that each community's assessed values reflect full and fair cash value (required at least every three years under a state-supervised revaluation cycle) and approves each town's tax rate before bills go out, ensuring compliance with Proposition 2½.

The Basic Formula

Once a town's assessors certify property values and its governing body sets a tax rate, the calculation is straightforward:

Annual Property Tax = (Assessed Value ÷ 1,000) × Tax Rate per $1,000

A $500,000 home in a town with a $12.00 rate: ($500,000 ÷ 1,000) × $12.00 = $6,000 per year, before any exemptions.

Quarterly Billing

Most Massachusetts communities bill quarterly. The first two quarters (due August 1 and November 1) are preliminary bills based on the prior fiscal year's tax, since the new rate typically isn't certified until late fall. The third and fourth quarter bills (due February 1 and May 1) are actual bills that apply the newly certified rate and true up the full year's tax, so a rate increase or decrease usually shows up as a larger or smaller adjustment in the February bill rather than spread evenly across all four payments.

Classification: Why Residential and Commercial Rates Often Differ

Under M.G.L. c.59 §2A, communities may adopt a split tax rate that shifts a larger share of the levy onto commercial, industrial, and personal property (CIP) and a smaller share onto residential property, up to a statutory maximum shift set by DLS regulation. This is why cities like Boston, Cambridge, Worcester, and Springfield post two different rates — a lower residential rate and a substantially higher CIP rate — while many smaller residential-heavy towns like Wellesley apply a single uniform rate to all property classes because they have little commercial tax base to shift the burden onto.

Proposition 2½: The Levy Limit vs. the Levy Ceiling

Proposition 2½, approved by Massachusetts voters in 1980 and codified at M.G.L. c.59 §21C, is the single biggest reason Massachusetts property tax bills behave differently from most other states. It operates through two separate caps that are easy to confuse but function very differently.

The Levy Limit: How Fast the Levy Can Grow Each Year

A community's levy limit is the maximum amount of property tax revenue it may raise (levy) in a given year. It grows automatically each year by two components, both added to the prior year's levy limit:

• An increase of 2.5% of the prior year's levy limit
• New growth — additional tax revenue attributable to new construction, subdivided lots, renovations, and other real additions to the tax base (not from rising market values or periodic revaluation)

New growth is calculated by applying the prior year's tax rate to the value of qualifying new development, so a town with a lot of new construction can grow its levy limit meaningfully faster than 2.5% without needing voter approval.

The Levy Ceiling: The Hard Outer Boundary

Separately, the levy ceiling caps the total levy a community can ever raise at 2.5% of the full and fair cash value of all its taxable property — a completely different calculation from the levy limit, based on total property value rather than the prior year's levy. In a community with a large and growing tax base, the levy ceiling is usually far above the levy limit, leaving room to grow; in a built-out or slow-growth community, the levy limit can approach the ceiling, leaving little or no additional room even if voters wanted to raise more.

Overrides: Permanently Raising the Levy Limit

An override, approved by a townwide ballot majority, permanently increases the levy limit itself — the additional amount becomes part of the base used to calculate every future year's levy limit. Critically, an override can never push the levy limit above the levy ceiling; a community already at or near its ceiling has no room for an override no matter how voters vote.

Exclusions: Temporary Increases That Can Exceed the Ceiling

A debt exclusion (for a specific bond, such as a new school building) or a capital outlay expenditure exclusion (for a one-time cash purchase) works differently still: voters approve raising the levy above the levy limit — and, unlike an override, above the levy ceiling too — for a limited or temporary period. Debt exclusions typically last for the life of the specific bond being repaid, then automatically expire; the additional revenue is never added to the base used for future levy-limit calculations. This is why a town can have a temporary spike in its tax rate tied to a school building project without that increase becoming permanent.

Exemption Programs: Elderly, Veterans, Blind & Residential Exemption

Massachusetts offers several statutory property tax exemptions under M.G.L. c.59 §5, plus a separate local-option residential exemption. Amounts and eligibility rules vary because many are set locally within state-defined ranges, so always confirm current figures with your city or town assessor before applying.

Elderly Exemption (Clause 41C)

Available to homeowners typically 65 or older (some communities that have adopted Clause 41C½ allow age 65 rather than the base age of 70) who meet income and "whole estate" (asset) limits set locally within state guidelines. The exemption itself ranges from $500 up to $1,000 depending on the local option amount a community has adopted; several cities, including Boston, provide $1,000 in relief with the potential for an additional $1,000 for especially low-income seniors. Income and asset limits vary meaningfully by community — for example, one municipality's FY2026 net income limit was $24,911 (single) / $37,367 (married), while others differ — so check your specific assessor's published FY2026 figures.

Veterans' Exemptions (Clauses 22–22F)

Veterans with a service-connected disability, Purple Heart recipients, Gold Star parents, and their surviving spouses qualify for tiered exemptions based on the nature and severity of the disability: $400 under the base Clause 22, rising to $750 (Clause 22A, loss of one foot/hand/eye or select combat decorations), $1,250 (Clause 22B, loss of both feet/hands/eyes), $1,500 (Clause 22C, total permanent disability with specially adapted housing), and a full exemption for paraplegic veterans and those with a 100% service-connected disability rating, or their surviving spouses. The 2024 HERO Act added local-option Clause 22J, letting individual communities double all these base amounts, and Clause 22I, an annual cost-of-living adjustment — so actual amounts can be higher depending on your city or town.

Blind Persons' Exemption (Clause 37A)

Homeowners registered as legally blind with the Massachusetts Commission for the Blind qualify for a $500 exemption, with no income limit, provided their ownership interest in the property is worth at least $5,000. Applications are typically due April 1 of the relevant fiscal year, filed with the local board of assessors.

The Residential Exemption: A Local-Option Shift, Not a State Mandate

Under M.G.L. c.59 §5C, a city or town may vote to adopt a residential exemption that exempts a flat percentage (up to 35%) of the average assessed value of all residential parcels in the community, applied against owner-occupied homes only. This isn't available statewide — only a limited number of communities have adopted it, including Boston, Cambridge, Somerville, Brookline, Chelsea, Waltham, Watertown, Nantucket, and several Cape Cod towns such as Provincetown, Tisbury, and Wellfleet. Boston's FY2026 residential exemption removes $351,108 from a qualifying owner-occupied home's assessed value, worth up to $4,353.74 in tax savings; Cambridge's FY2026 exemption (a 30% factor) removes $510,208. Because the exemption is funded by shifting the burden onto non-owner-occupied and commercial property within the same community, it only benefits owner-occupiers in towns that have specifically adopted it — renters and non-resident owners in those same towns see no benefit and effectively subsidize it.

FY2026 Property Tax Rates: City & Town Comparison

Because each of Massachusetts's 351 communities certifies its own rate annually through DLS, effective rates vary enormously depending on local property values, the size of the commercial tax base, and how aggressively a community has shifted burden through classification. The table below shows certified FY2026 rates (dollars per $1,000 of assessed value) for a sample of cities and towns spanning the state's range, compiled from each municipality's official assessing or finance department.

FY2026 Rates — Selected Massachusetts Cities & Towns

Reading the Table

Springfield and Worcester — mid-size Gateway Cities with more modest home values and a heavier reliance on residential and CIP splits to fund services — post noticeably higher nominal rates than affluent Boston suburbs like Newton and Wellesley, where high property values mean a lower rate raises the same or more revenue per household. Cambridge's low $6.67 residential rate reflects both an exceptionally large, fast-growing commercial and lab-space tax base (shifted to a $14.07 CIP rate) and its residential exemption. Provincetown is unusual in that its residential rate ($6.13) is actually slightly higher than its CIP rate ($5.69), reflecting the town's small, largely residential and seasonal-rental tax base rather than a typical urban split favoring residential relief. Statewide, FY2026 residential rates span from about $2.18 per $1,000 in Hancock to about $20.50 per $1,000 in Wendell, and the average single-family tax bill is $8,113 on an average assessed value of $742,986, according to Massachusetts DOR/DLS statewide data.

Nominal Rate Isn't the Whole Story

A low nominal rate doesn't necessarily mean a low tax bill — Cambridge's $6.67 rate applies to some of the highest average home values in the state, so many Cambridge homeowners still pay a substantial dollar amount despite the modest-looking rate. Always multiply the actual rate by your specific property's assessed value (available from your town assessor's online parcel lookup) rather than comparing nominal rates alone across communities with very different average home values.

Worked Example: $650,000 Home in Worcester

This example applies Worcester's official FY2026 residential rate to a $650,000 home — close to the city's typical single-family range — and compares the result against two other communities from the table above to illustrate how much location alone changes the bill.

Step 1: Confirm the Assessed Value

Assume the home's FY2026 assessed value, certified by the Worcester Board of Assessors as of the January 1, 2025 valuation date, matches its $650,000 market value (Worcester does not offer a residential exemption, so no local exemption applies before this step for a typical owner without an elderly, veteran, or blind exemption).

Step 2: Apply Worcester's FY2026 Residential Rate

($650,000 ÷ 1,000) × $13.28 = $8,632 per year

Step 3: Compare to Other Communities at the Same Value

Applying each city/town's FY2026 residential rate to the same $650,000 assessed value, before any exemptions:

• Springfield ($15.46): $650,000 ÷ 1,000 × $15.46 = $10,049/year
• Worcester ($13.28): $8,632/year
• Boston ($12.40): $650,000 ÷ 1,000 × $12.40 = $8,060/year (before Boston's residential exemption, which would reduce this further for an owner-occupant by up to $4,353.74)
• Wellesley ($10.17): $650,000 ÷ 1,000 × $10.17 = $6,611/year
• Cambridge ($6.67): $650,000 ÷ 1,000 × $6.67 = $4,336/year (before Cambridge's residential exemption, which would reduce this considerably further for an owner-occupant)

What This Shows

The same $650,000 home generates roughly $4,300 to $10,000 in annual property tax depending purely on which Massachusetts community it sits in — a difference driven by each town's levy limit, its commercial tax base, whether it has adopted a residential exemption, and how it has classified property under Proposition 2½. If this homeowner qualified for the elderly exemption (Clause 41C, $500–$1,000), a veteran's exemption (Clauses 22–22F, $400 to full exemption), or the blind persons' exemption (Clause 37A, $500), the applicable dollar amount would be subtracted directly from whichever bill above applies, on top of any residential exemption already reflected.

Appealing Your Assessment: The Abatement Process

If you believe your Massachusetts property has been over-assessed relative to its fair market value as of the January 1 assessment date, you can file for an abatement with your local board of assessors under M.G.L. c.59 §59.

Deadline

Abatement applications are due on the date your actual (third-quarter) tax bill is due — typically February 1 for communities on quarterly billing — or 30 days after the actual bill was mailed if later. This deadline is strict; assessors generally cannot accept late applications, and paying your bill in full while it's under appeal does not extend or waive the deadline.

What to Include

A strong abatement application generally includes recent comparable sales in your immediate neighborhood, any factual errors in your property's record card (incorrect square footage, bedroom/bathroom count, lot size, or condition), and, where relevant, a recent independent appraisal. Assessors are looking for evidence your assessed value exceeds fair market value as of January 1 of the relevant year — general complaints about tax rates or town spending are not grounds for abatement, since the rate itself is set separately from your individual valuation.

If You're Denied

If your local board of assessors denies the abatement (or fails to act within three months, which counts as a denial), you can appeal further to the state Appellate Tax Board (ATB) within three months of the local decision. Many disputes are resolved informally with the local assessor's office before reaching that stage, so start by scheduling a conversation with your assessor and reviewing your property's record card for errors before filing a formal application.
