Where Hillsborough's $21.05 goes
The rate is four rates added together. The local school rate is the biggest piece at $10.98, 52% of the total. Together the two school rates (local $10.98 and state education $1.09) come to $12.07, or 57% of every tax dollar. The municipal rate of $7.95 funds Hillsborough's own town budget, and the county rate of $1.03 is Hillsborough's share of the Hillsborough County budget.
| Part of the rate | Hillsborough | Share | NH median | Difference |
|---|---|---|---|---|
| Municipal | $7.95 | 38% | $4.59 | +$3.36 |
| County | $1.03 | 5% | $1.34 | −$0.31 |
| Local school | $10.98 | 52% | $9.75 | +$1.23 |
| State education | $1.09 | 5% | $1.13 | −$0.04 |
| Total | $21.05 | 100% | $16.90 | +$4.15 |
Medians are taken part by part across all 234 municipalities, so the four part medians do not add up to the median total.
Hillsborough's rate in 2024 and 2025
The total rate fell $12.39 (37.05%) from $33.44 in 2024, and the part that moved most was the local school rate, down $6.45. Over the same year Hillsborough's assessed valuation (without utilities) went from $570,660,352 to $977,969,126, up 71.37%. A jump in valuation that size is what an assessment update looks like (RSA 75:8-a requires a reappraisal at least every five years): the same budget spread over more assessed value gives a lower rate, so a lower rate does not by itself mean a lower bill. A property whose assessment rose faster than the town's 71.37% can still pay more. The guide to rates and revaluations works through the arithmetic.
Tax on common assessed values in Hillsborough
| Assessed value | 2025 bill | At the 2024 rate | Versus NH median rate |
|---|---|---|---|
| $200,000 | $4,210.00 | $6,688.00 | +$830.00 |
| $300,000 | $6,315.00 | $10,032.00 | +$1,245.00 |
| $400,000 | $8,420.00 | $13,376.00 | +$1,660.00 |
| $500,000 | $10,525.00 | $16,720.00 | +$2,075.00 |
| $750,000 | $15,787.50 | $25,080.00 | +$3,112.50 |
Each figure is the assessed value divided by 1,000 and multiplied by the rate, before exemptions and credits. These are assessed values, the number printed on a Hillsborough bill, not sale prices: New Hampshire towns assess as of April 1 and many sit above or below market value between revaluations, so a $300,000 assessment can belong to a house that would sell for more or less. The "2024 rate" column applies last year's $33.44 to the same assessment, which overstates the change for most owners in a year when assessments were updated.
How Hillsborough compares in Hillsborough County and the state
Among the 31 municipalities in Hillsborough County, Hillsborough ranks 12th highest; the county median is $20.67, so Hillsborough sits $0.38 above it. The next higher rate in the county is Weare at $21.64, and the next lower is Mont Vernon at $21.04. Statewide, 78% of municipalities have a lower total rate than Hillsborough; in 2024 it ranked 4th.
Municipalities with the closest rates anywhere in the state: Mont Vernon ($21.04, Hillsborough), Lancaster ($21.07, Coös), Greenfield ($21.00, Hillsborough), Strafford ($20.96, Strafford). A rate only compares bills fairly between towns that assess at a similar share of market value; the DRA's equalization ratio for each town measures that share, and the guide to assessed and market value explains how to use it.
What Hillsborough raises and from what base
The DRA set Hillsborough's 2025 rate on November 21, 2025 against a total assessed valuation of $1,028,917,326 including utilities, of which $50,948,200 (4.95%) is utility property. The state education rate applies only to the $977,969,126 without utilities (RSA 76:3). The total commitment, the property tax Hillsborough bills for the year, is $21,747,051, about $3,662 for each of the 5,939 residents counted in the 2020 census. The commitment is $143,875 more than the four rates alone raise on the two valuations ($21,603,176), so the DRA total includes amounts billed alongside them.
Appealing a Hillsborough assessment
Abatement starts with Hillsborough, not the state. When the final 2025 bill is mailed by December 31, 2025, the written application goes to the selectmen or assessors by March 1, 2026 (RSA 76:16, I(b)), the town decides by July 1, and an appeal to the Board of Tax and Land Appeals ($65 fee) or superior court is due by September 1, 2026. A bill mailed after December 31 moves each date to two, six and eight months after the mailing. The Board compares the assessment divided by the town's equalization ratio with the property's market value on April 1; the New Hampshire appeal page sets out the full procedure and the appeal check does that division.
