Why doesn't New Hampshire have one statewide property tax rate?
New Hampshire has no broad-based income or sales tax, so property tax carries more of the load for towns, counties, and schools than it does in most states. Each town's total rate is built from four pieces: a municipal rate for town services, a county rate, a state education rate set by the legislature, and a local education rate that varies with what that town's school district spends. The Department of Revenue Administration finalizes every town's combined rate once all four pieces are known for the year.
What was Bedford's property tax rate?
The most recently confirmed figure available is Bedford's 2023 total rate of $14.80 per $1,000 of assessed value, made up of $3.29 municipal, $0.86 county, $1.26 state education, and $9.39 local education, per the NH Department of Revenue Administration's finalized 2023 municipal tax rates. Separately, ATTOM Data Solutions reported Bedford's effective property tax rate (tax bill as a percentage of market value, a different measurement than the mill rate above) at 1.35% for 2024. Two years is long enough for a rate to move, so if you're pricing a specific Bedford property, pull the current confirmed rate from the town's assessing office or PrimeMLS rather than working from a number this old.
Why can't I just compare mill rates between towns?
A town's nominal rate only tells you part of the story, because towns don't all assess property at the same percentage of market value. The Department of Revenue Administration publishes an equalization ratio for every town each year specifically to correct for this, and that ratio moves more than most people expect. Barrington's own published history shows its ratio at 97.6% in 2023, 87.0% in 2024, and 78.2% in 2025, over just three years, per the Town of Barrington's tax rate page. A town with a lower nominal rate but a lower ratio can carry a higher real tax burden than a town with a higher rate and a ratio closer to 100%. The Department's annual "Comparison of Full Value Tax Rates" report does this adjustment for every municipality in the state.
What's the average property tax rate in New Hampshire right now?
The Department of Revenue Administration's 2025 compilation covers 259 municipalities, including towns, cities, and unincorporated places, with an average total rate of $17.10 per $1,000 of assessed value. The spread is wide: Hart's Location sits at $2.62 and Charlestown at $36.54. A handful of towns from that same 2025 data set illustrate the range: Acworth at $16.06, Alton at $13.50, Amherst at $23.98, and Brookline at $24.64.
When does the current year's rate actually get finalized?
Rates are set town by town on their own individual schedules. The Department of Revenue Administration issues a "Director-Approved Final Tax Rate" for each town once its municipal, school, and county figures are all submitted, typically between October and December. Lyme's 2025 rate, for example, was approved on October 24, 2025. Nottingham's 2025 rate was finalized on November 26, 2025 and posted with a note that tax bills go out the first week of December, due in January. Most towns bill twice a year: a July estimate based on roughly half of the prior year's total, then a December or January bill that reconciles to the new rate, which is often the larger of the two.
Property tax is one of the biggest swing factors in a New Hampshire rental's monthly numbers, and it varies by hundreds of dollars a month just from crossing a town line. My calculator runs the full monthly and annual cash flow for a specific address using that town's actual rate.
