Barnstable Property Tax: FY2026 Rates, the 30% Exemption, and Five Fire Districts
Barnstable's FY2026 property tax picture is genuinely better for homeowners than FY2025's: the residential rate dropped to $6.80 per $1,000 of assessed value (from $6.94) and the residential exemption grew to 30% of the average assessed value, worth $274,787 in exempted value (up from 25% and $233,792) - both moving in the same, homeowner-favorable direction in the same year. But the town-wide rate is only half the story here. Barnstable is unusual among Cape Cod towns in layering a separate fire-district tax rate on top of the town rate, and which of the town's five fire districts a property sits in - Barnstable, Cotuit, Centerville-Osterville-Marstons Mills (COMM), West Barnstable, or Hyannis - can change the effective total rate by more than $1.50 per $1,000. This guide walks through the FY2026 numbers, the year-over-year shift, the fire-district overlay in detail, the Community Preservation Act surcharge, and how Barnstable compares to its Cape Cod neighbors.
How Massachusetts Bills Property Tax, and the Proposition 2½ Mechanic Behind It
Massachusetts bills property tax the standard way: assessed value multiplied by a tax rate, expressed as a dollar amount per $1,000 of assessed value. There's no owner-occupied-versus-non-owner assessment ratio built into the base billing method - every Barnstable property starts from the same rate-times-value formula, whether it's a year-round home in Marstons Mills, a seasonal cottage near Craigville Beach, or a commercial building in downtown Hyannis. What changes that picture for owner-occupants is a separate residential exemption layered on top of the base rate, covered below, plus the fire-district add-on that makes Barnstable's total tax picture more complicated than most Cape towns.
The base rate itself is governed by Proposition 2½, a 1980 Massachusetts ballot law that applies statewide. It works through two caps: a levy ceiling, which limits a town's total property tax levy to 2.5% of the total assessed value of all taxable property in town, and a levy limit, which caps how much that total levy can grow year to year - at most 2.5% over the prior year's levy limit, regardless of how much individual assessed values rise in that same year. New construction is excluded from that 2.5% growth cap, so newly built property adds tax revenue without counting against the limit. A town can exceed the annual growth limit only through a voter-approved override (a permanent increase) or a debt exclusion (a temporary increase tied to specific debt). Despite the cap, Massachusetts property taxes have nearly doubled in real terms since 1984 statewide - Proposition 2½ slows the pace of growth, it doesn't prevent it, especially as reassessments catch up to Cape Cod's fast-appreciating waterfront values.
FY2026 Versus FY2025: A Rate Cut and a Bigger Exemption, Together
Barnstable's FY2026 residential rate is $6.80 per $1,000 of assessed value, down from $6.94 in FY2025. The commercial, industrial, and personal property rate for FY2026 is $5.94 per $1,000. At the same time, the town's residential exemption - a program that shields a fixed dollar amount of a qualifying owner-occupied home's assessed value from taxation, shifting more of the burden onto second homes, rentals, and non-owner-occupied property - grew from 25% of the average assessed residential value in FY2025 (worth $233,792 in exempted value) to 30% in FY2026 (worth $274,787 in exempted value).
That combination is worth stating plainly: it's genuinely uncommon for a town's headline rate to fall and its owner-occupant exemption to grow in the same year, since a falling rate on its own can still mean a rising bill if assessed values climbed faster than the rate dropped. Here, both levers moved in the qualifying homeowner's favor at once, which is a real and citable year-over-year improvement rather than an artifact of rounding or a partial picture. It does not, however, mean every bill in town went down - a specific property's actual bill still depends on its own assessed value, its fire district, and whether it qualifies for the residential exemption in the first place (typically requiring the home to be the owner's primary, occupied residence as of the relevant assessment date, with an application filed through the Assessor's office).
The Fire District Overlay: Why Your Village Matters as Much as the Town Rate
Barnstable is unusual on Cape Cod in that the town-wide rate is not the whole story. In addition to the town's base residential or commercial rate, most Barnstable properties also pay a separate tax to one of five independent fire districts, each of which sets its own rate to fund its own fire and, in some districts, water services. Which district a property falls into depends on where in town it sits, and the rates vary meaningfully: Barnstable Fire District is $2.81 per $1,000, Cotuit Fire District is $2.07, the Centerville-Osterville-Marstons Mills (COMM) Fire District is $1.15, West Barnstable Fire District is $2.66, and the Hyannis Fire District is $2.40 residential and $3.82 commercial - the only one of the five with a split residential/commercial rate, mirroring the town's own residential-versus-commercial split at the fire-district level.
The practical effect is that two homes with identical assessed values in Barnstable can carry meaningfully different total tax bills depending only on which village, and therefore which fire district, they're in. Add the town's $6.80 residential rate to the COMM district's $1.15 and the effective combined rate is $7.95 per $1,000; add the same $6.80 to the Barnstable Fire District's $2.81 and it's $9.61 per $1,000 - a gap of roughly $1.66 per $1,000, or about $1,660 a year on a $1 million assessed home, purely from the fire-district overlay. Anyone comparing "Barnstable's property tax rate" to another town's single combined rate should account for this: the $6.80 town figure by itself understates the effective rate for most properties in town, sometimes substantially.
The Community Preservation Act Surcharge
On top of the town rate and the applicable fire-district rate, Barnstable also levies a Community Preservation Act (CPA) surcharge equal to 3% of the annual town property tax, a local-option surcharge Massachusetts law allows any town to adopt by ballot vote (up to a 3% maximum) to fund open space and land conservation, historic preservation, community (affordable) housing, and outdoor recreation projects. Where adopted, the CPA surcharge is typically collected on the same tax bill as the base levy, and towns that adopt it also become eligible for an annual distribution from the statewide CPA Trust Fund, which supplements local surcharge revenue at a match percentage that varies year to year depending on statewide participation and Trust Fund receipts - it is not a fixed or guaranteed match rate.
Because CPA surcharge revenue, exemption rules for lower-income or lower-value properties, and the statewide match percentage can all change from year to year, homeowners and buyers should confirm the current CPA surcharge amount and any applicable exemption directly with the Barnstable Assessor's office rather than assuming this year's figures carry forward unchanged.
How Barnstable Compares to Its Cape Cod Neighbors
Barnstable sits in the Mid Cape cluster alongside Yarmouth and Dennis, but specific FY2026 tax rates for those two immediate neighbors were not found in the research behind this page and should not be assumed to resemble Barnstable's - each is set independently through its own town meeting or council process under Proposition 2½. What is available for comparison is a set of Upper Cape rates from this site's own published research: Falmouth's FY2026 rate is roughly $5.87 per $1,000, Mashpee's is roughly $6.41-6.42, Bourne's is roughly $7.65-7.81, and Sandwich's is the highest of that group at roughly $10.19-10.57. Barnstable's $6.80 town rate lands squarely in the middle of that Upper Cape range - close to Mashpee's, well below Sandwich's - though, as covered above, Barnstable's effective rate for most properties runs higher than the bare $6.80 once its fire-district add-on is included, a layer none of those four Upper Cape towns applies in the same way.
On the exemption side, Barnstable's 30% residential exemption is also worth setting in context: it's higher than Mashpee's comparatively modest 5% exemption, but lower than the 35% adopted by Provincetown and (for FY2027) Chatham, and matches the 30% used by both Truro and Wellfleet. As with the rate itself, exemption percentages are a town-by-town local option under Massachusetts law, not a Cape-wide standard, and towns with a larger share of seasonal or investment property tend to lean toward higher exemption percentages since there's a bigger non-owner-occupied base to shift the burden onto.
Confirming Your Fire District, Eligibility, and Current Figures
Because Barnstable's effective tax bill depends on the combination of the town rate, the residential exemption (if the property qualifies), the specific fire district, and the CPA surcharge, a buyer or homeowner cannot reliably estimate a bill from the town-wide $6.80 rate alone. The single most useful step is confirming, in writing, which of the five fire districts - Barnstable, Cotuit, COMM, West Barnstable, or Hyannis - a specific parcel falls into, since that determines a meaningful share of the total bill and isn't always obvious from a village name alone (village and fire-district boundaries don't always line up exactly).
Everything in this guide - the FY2026 and FY2025 rates, the residential exemption figures, the five fire-district rates, the CPA surcharge, and the neighboring-town comparisons - reflects the most recent figures found in research and can change with each year's rate-setting process, each fire district's own budget vote, and any future adjustment to the exemption percentage or CPA surcharge. This page is not legal, tax, or financial advice. A licensed tax professional, together with the Barnstable Assessor's office and the relevant fire district, should confirm any current rate, assessed value, fire-district assignment, or exemption eligibility detail before it's used in a purchase decision or a household budget.

Property tax figures are drawn from this site's Barnstable competitive research: FY2026 rates of $6.80 per $1,000 (residential) and $5.94 per $1,000 (commercial/industrial/personal property), down from FY2025's $6.94 per $1,000; the residential exemption growing from 25% ($233,792 exempted value) in FY2025 to 30% ($274,787 exempted value) in FY2026; and the five fire-district rates - Barnstable Fire District $2.81, Cotuit Fire District $2.07, Centerville-Osterville-Marstons Mills (COMM) Fire District $1.15, West Barnstable Fire District $2.66, and Hyannis Fire District $2.40 residential/$3.82 commercial (the only split-rate district). Massachusetts' Proposition 2½ mechanics (the levy ceiling and levy limit, the new-construction exclusion, override and debt-exclusion provisions, and the statewide near-doubling of real property tax levels since 1984 despite the cap) and the general Community Preservation Act surcharge structure (a local-option surcharge up to 3% of the town levy, matched by a variable annual state Trust Fund distribution) are drawn from this site's Cape Cod regional research. Comparative Upper Cape rates for Falmouth (~$5.87), Mashpee (~$6.41-6.42), Bourne (~$7.65-7.81), and Sandwich (~$10.19-10.57), along with comparative residential exemption percentages for Mashpee (5%), Provincetown (35%), Truro and Wellfleet (30% each), and Chatham (35% for FY2027), are drawn from this site's Mashpee property tax research. Specific FY2026 rates for Barnstable's immediate Mid Cape neighbors, Yarmouth and Dennis, were not found in the reviewed research and are not assumed here. Tax rates, exemptions, fire-district assignments, and the CPA surcharge all change annually - confirm all current figures directly with the Barnstable Assessor's office and the relevant fire district before making any purchase, rental, or financial decision.
