Where Washington's $15.95 goes
The rate is four rates added together. The local school rate is the biggest piece at $6.34, 40% of the total. Together the two school rates (local $6.34 and state education $1.23) come to $7.57, or 47% of every tax dollar. The municipal rate of $5.75 funds Washington's own town budget, and the county rate of $2.63 is Washington's share of the Sullivan County budget.
| Part of the rate | Washington | Share | NH median | Difference |
|---|---|---|---|---|
| Municipal | $5.75 | 36% | $4.59 | +$1.16 |
| County | $2.63 | 16% | $1.34 | +$1.29 |
| Local school | $6.34 | 40% | $9.75 | −$3.41 |
| State education | $1.23 | 8% | $1.13 | +$0.10 |
| Total | $15.95 | 100% | $16.90 | −$0.95 |
Medians are taken part by part across all 234 municipalities, so the four part medians do not add up to the median total.
Washington's rate in 2024 and 2025
The total rate rose $0.71 (4.66%) from $15.24 in 2024, and the part that moved most was the municipal rate, up $0.77. Over the same year Washington's assessed valuation (without utilities) went from $369,046,927 to $375,131,444, up 1.65%. With the tax base nearly flat, the higher rate passes straight through to bills: the same $300,000 assessment owes $213.00 more than in 2024.
Tax on common assessed values in Washington
| Assessed value | 2025 bill | At the 2024 rate | Versus NH median rate |
|---|---|---|---|
| $200,000 | $3,190.00 | $3,048.00 | −$190.00 |
| $300,000 | $4,785.00 | $4,572.00 | −$285.00 |
| $400,000 | $6,380.00 | $6,096.00 | −$380.00 |
| $500,000 | $7,975.00 | $7,620.00 | −$475.00 |
| $750,000 | $11,962.50 | $11,430.00 | −$712.50 |
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 Washington 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 $15.24 to the same assessment.
How Washington compares in Sullivan County and the state
Among the 15 municipalities in Sullivan County, Washington ranks 10th highest; the county median is $17.30, so Washington sits $1.35 below it. The next higher rate in the county is Acworth at $16.06, and the next lower is Lempster at $15.63. Statewide, 42% of municipalities have a lower total rate than Washington; in 2024 it ranked 159th.
Municipalities with the closest rates anywhere in the state: East Kingston ($15.94, Rockingham), Franconia ($15.94, Grafton), Acworth ($16.06, Sullivan), Grafton ($15.83, Grafton). 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 Washington raises and from what base
The DRA set Washington's 2025 rate on November 20, 2025 against a total assessed valuation of $378,758,944 including utilities, of which $3,627,500 (0.96%) is utility property. The state education rate applies only to the $375,131,444 without utilities (RSA 76:3). The total commitment, the property tax Washington bills for the year, is $6,183,960, about $5,188 for each of the 1,192 residents counted in the 2020 census. The commitment is $147,217 more than the four rates alone raise on the two valuations ($6,036,743), so the DRA total includes amounts billed alongside them.
Appealing a Washington assessment
Abatement starts with Washington, 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.
