Using the 2025 rates, an equivalent lakefront cottage in Moultonborough and in Wolfeboro would have very different annual tax amounts. Moultonborough's 2025 municipal tax rate landed at $5.33 per $1,000 of assessed value, a decrease from $5.65 the year before. Wolfeboro's 2025 rate came in at $8.36 per $1,000. On a $700,000 assessment, that gap alone is the difference between roughly $3,731 and $5,852 a year, before either owner touches insurance, dock maintenance, or a septic pump-out.

Buyers comparing towns around the lake tend to read that spread as a verdict on which town runs a tighter budget. That's not what's happening. The gap traces back to something structural: who lives in these houses, and for how much of the year.

Four Lakes Region Towns, Four Different Rates

Pull the 2025 numbers for four towns Costantino Real Estate covers around Winnipesaukee and the spread only widens. Moultonborough sits at $5.33 per $1,000. Tuftonboro, just across the town line, comes in at $6.40, according to its tax collector's office. Wolfeboro runs $8.36. Ossipee, inland and off the main lake, posts a base rate of $12.77 per $1,000 before any fire-precinct add-on, per the town's own published rate sheet.

Statewide, New Hampshire's 2025 rates ranged from roughly $2.62 per $1,000 up past $36. Every one of these towns sits on the low end of that range. The question worth asking isn't why Moultonborough looks cheap next to Charlestown or Berlin. It's why Moultonborough looks cheap next to Tuftonboro and Wolfeboro, two towns with the same lake, the same water quality concerns, and roughly the same category of buyer walking through the door.

Where Most of That Rate Actually Comes From

In New Hampshire, the local education tax is the heaviest single line on almost every town's bill. Wolfeboro's 2025 breakdown shows this clearly: of its $8.36 total, $3.37 came from the local school tax alone, with $3.21 for the town, $1.07 for the state education tax, and $0.71 for the county. Local education spending is the lever that moves the most, because it's set by each town's own school budget rather than by a statewide formula.

Moultonborough's schools are not small or underfunded. SAU 45 runs two buildings: Moultonborough Central School for pre-K through 6th grade, and Moultonborough Academy for grades 7 through 12, serving roughly 350 students at a student-teacher ratio near 8 to 1. Running that district costs real money. The reason it doesn't translate into a heavier per-parcel tax burden isn't a smaller budget. It's a much larger base of taxable property paying into that budget without adding pupils to it.

The Second-Home Math Behind the Number

Moultonborough carries the highest concentration of seasonal homes anywhere in the Lakes Region, with roughly six in ten housing units in town classified as seasonal rather than year-round. A seasonal owner on Moultonborough Neck or along Long Island pays full property tax on a high-value shorefront parcel and, in the overwhelming majority of cases, sends no children to Moultonborough Central or the Academy. That owner is pure revenue against the school budget, not a cost against it.

Stack enough of those parcels next to each other and the math works itself out. A town with 66 miles of lake shoreline, more than any other municipality in New Hampshire, and a housing stock weighted toward seasonal ownership ends up needing a smaller local school tax per dollar of assessed value than a town where more of the waterfront has converted to full-time, year-round households with kids in the district. That's the actual mechanism behind the $5.33 rate. It isn't thrift. It's composition.

Why Concord Calls Moultonborough a Donor Town

The same dynamic that keeps Moultonborough's local rate low also puts it on the wrong side of an unresolved fight over how New Hampshire funds schools statewide.

Every town collects a State Education Property Tax, and in towns with enough property wealth, that tax raises more money than the town is required to spend on an adequate education. Moultonborough is one of these towns. Reporting from New Hampshire Public Radio detailed a specific figure: $4.6 million of a $5.1 million excess in Moultonborough's state education tax collection represented more than a quarter of the town's $16.6 million school budget. Town Administrator Charles Smith told NHPR losing that money "will have a serious impact on the education that the town is able to provide," and noted it would also stall the town's plan to expand sewer lines along its Winnipesaukee shoreline, a project aimed directly at reducing the algal and cyanobacteria blooms that show up in the lake's warmer months.

That excess tax revenue, generated in large part by high-value seasonal property, doesn't just fund classrooms. It's tied to infrastructure that affects water clarity on the same lake that makes these parcels valuable in the first place. The litigation over whether donor towns like Moultonborough get to keep that excess, rather than remit it to towns with less property wealth, has moved through the courts more than once. Whatever it settles into, a shift in that formula would land differently in Moultonborough than in a town like Ossipee, which isn't collecting a comparable surplus to begin with.

What This Means If You're Weighing Towns, Not Just Homes

For a buyer comparing carrying cost across the lake, the practical takeaway isn't that Moultonborough is a trap or that Wolfeboro is overpriced on taxes. It's that the $5.33 rate is a function of a specific, identifiable arrangement: a high share of seasonal ownership funding a school system most of those owners don't use, plus a revenue surplus the town gets to keep only as long as state law allows it. Neither piece is guaranteed to hold in its current form for the next ten or twenty years of ownership.

If you're pricing out two similar properties on opposite sides of a town line, run the actual carrying cost rather than assuming the posted rate tells the whole story. Assessed value, not market value, is what the rate gets multiplied against, and assessment ratios differ by town and by year. A property assessed close to its sale price in one town and well under in another can flip which side of the comparison actually costs less to hold. For a second-home buyer weighing decades of ownership, that's worth ten minutes with a calculator before it's worth an opinion about which town runs things better.

Does a lower town rate always mean a lower total bill? Not by itself. The rate is multiplied against assessed value, and assessment practices vary by town. A precise comparison requires the actual assessed value of the specific parcels involved, not just the posted rate.

Could Moultonborough's rate rise if more seasonal homes convert to full-time residences? The mechanism works in both directions. More year-round households sending children into SAU 45 would add cost to the school budget without necessarily adding proportional tax base, which would push the local education portion of the rate upward over time.

Does the donor-town surplus affect anything beyond the tax bill? Directly, yes. In Moultonborough's case, the excess funds cited by the town administrator are tied to a shoreline sewer expansion aimed at water quality, the kind of infrastructure that matters to anyone holding lakefront property for the long term.

Tax rates are one line on a much longer list when you're comparing towns around the same lake. If you want that full carrying-cost picture worked out before you write an offer, not after the first bill lands, Costantino Real Estate has been doing this math for buyers across Moultonborough, Tuftonboro, Wolfeboro, and Ossipee for years and can walk you through it town by town.
