Executive Summary
How Vermont funds schools
How a school-budget vote in your town turns into a number on your property-tax bill, and why the two numbers don't always move together.
The arithmetic, step by step
Every spring the state runs the same recipe for every district in Vermont:
-
Your town's voters approve a school budget on Town Meeting Day.
-
The state subtracts local revenue and divides by the district's weighted students. That's education spending per pupil.
-
The state turns spending per pupil into your town's tax rate: divide by the yield, then by your town's CLA factor.
The rest of this page walks through each piece with the FY27 budgets as passed for the three WSESU districts, the same chain the WSESU merger tool shows under "See the math", so every figure ties to the rate the State actually set.
Every school-tax dollar goes into one statewide pot
In most states your town keeps its own school taxes. In Vermont, every homestead school-tax dollar from every town goes into the Education Fund, and the fund pays each district the budget its voters approved. Your rate therefore depends on what everyone in Vermont is spending, not only on your own town.
The number that matters is education spending per weighted pupil
The state doesn't compare budgets; it compares education spending per pupil: the budget, less local revenue such as tuition the district collects, divided by its students. And the pupil count isn't a headcount. Each student is weighted (older grades, English learners, students from lower-income households, and small rural schools count for more), and the count is averaged over several years so one big graduating class doesn't swing the rate. That figure is called LTWADM.
Above the excess-spending threshold, every dollar counts twice
To discourage runaway spending, Vermont sets a per-pupil excess-spending threshold each year: $16,470 for FY27 , and Act 169 lowers the FY28 line to 115.5% of the inflated statewide base once it is published. Spending above it is counted twice when the rate is set, so a district over the line has its rate set as if it spent even more. Every WSESU district was over the line in FY27; the pills show by how much.
Hartland, for example, was tested at $17,983 per pupil in FY27, $1,513 over the line, so its rate was set as if it spent $19,496. Bond principal is excluded from the test (Weathersfield: $408 per pupil); the Property Tax Rate Calculation page for each district shows the full FY28 worksheet.
Divide by the yield to get the equalized homestead rate
The yield is one number the legislature sets each year for the whole state: the spending per pupil that a $1.00 tax rate is meant to raise. Spend exactly the yield and your equalized homestead rate is $1.00; spend twice the yield and it's $2.00. The FY27 yield is $9,401 ; the estimated FY28 yield arrives in the Tax Commissioner's December 1 letter.
Because the yield is set against statewide spending, it moves every year. A perfectly flat local budget can still produce a different rate if the yield changed. A small, phasing-out "Act 84" discount from the 2024 pupil-weighting transition comes off at the very end (Hartland: 0.043 per $100 in FY27; 40% of that in FY28, and gone by FY30).
Divide by your town's CLA factor to get the rate on your bill
Towns reappraise property in different years, so two identical houses can sit on two grand lists at different values. The Common Level of Appraisal (CLA) corrects for that: it's the state's estimate of how close your town's grand list is to market value, expressed relative to the statewide average. A factor below 100% means the town is under-appraised, so the rate is divided up to compensate; a town fresh off a reappraisal can sit above 100%. A reappraisal moves the rate but leaves the bill itself about where it was.
The rates and factors on this page are the ones the Vermont Department of Taxes set for FY27 (FY2027 Education Property Tax Rate Table, July 29, 2026). The Department works from unrounded per-pupil figures, so this walkthrough's own subtraction lands within a few ten-thousandths of its district rate; the district rate and the homestead rate shown are the Department's, to the digit.
Why "our budget went up 3%" can become "my bill went up 8%"
Three of the numbers in the recipe are set outside your town, and all three move every year:
- Fewer weighted pupils. A 3% budget increase spread over fewer students is a bigger increase per pupil, and can push a district over the excess-spending line.
- The yield moved. If statewide spending grew faster than the Education Fund, the yield drops and every rate in Vermont rises.
- Your CLA moved. Rising home prices pull the CLA down between reappraisals, which pushes the rate on the bill up even when the equalized rate is flat.
Put it together: what lands on the bill
The same recipe, run for each WSESU town with the FY27 budgets as passed.
| Town | Spending per pupil | Rate basis | Equalized rate | − Act 84 | District rate | ÷ CLA ÷ SA | FY27 homestead rate | Home value | School tax |
|---|---|---|---|---|---|---|---|---|---|
| Hartland | $17,983 | $19,496 | 2.0738 | 0.043 | 2.0307 | 0.8007 | 2.5362 | $200,000 | $5,072 |
| Windsor | $17,024 | $17,578 | 1.8698 | 0.051 | 1.8187 | 1.3441 | 1.3531 | $200,000 | $2,706 |
| West Windsor | $17,024 | $17,578 | 1.8698 | 0.051 | 1.8187 | 1.4108 | 1.2891 | $200,000 | $2,578 |
| Weathersfield | $17,073 | $17,268 | 1.8368 | 0.043 | 1.7937 | 0.8271 | 2.1687 | $200,000 | $4,337 |
Rates are dollars per $100 of assessed value. Education spending is each district's FY27 General Fund budget as adopted less offsetting revenue (Hartland $200,000, FY25 surplus, one-time; not in FY28+; Mt. Ascutney $1,526,474), divided by FY27 weighted pupils, and tested against the FY27 threshold of $16,470 and yield of $9,401. The district rates, CLA ÷ SA factors and homestead rates are the Department of Taxes' FY27 figures as set; the WSESU merger tool builds the same steps from the as-passed budgets. The school tax column applies each town's rate to the same $200,000 home value so the towns compare like for like; your own bill scales with your assessed value.
