A buyer touring a Niskayuna listing this fall will see two numbers on the disclosure sheet that feel solid: the property taxes and the water and sewer bill. Both are printed, both look official, and neither one is the number that buyer will actually pay once the deed changes hands.
That gap is not a paperwork error. It is the product of two mechanisms working at the same time, one financial and one municipal, and both just moved. New York's STAR school tax exemption does not travel with the house. And Niskayuna's water and sewer rates, after three years of public fights over billing, were rebuilt into a new structure that took effect this fall. A buyer relying on the seller's last bill is pricing a house that no longer exists on paper.
The Bill That Already Expired
Niskayuna raised water and sewer rates in May 2023 to close budget gaps. The water district had run a $245,047 deficit and Sewer District 6 had come in $229,959 short of budget in 2022, so the town board voted to close the difference. The new rates did not show up on residents' bills until the spring of 2024, and when they did, homeowners opened bills that had jumped by hundreds of dollars in a single billing cycle. The town ended up resending bills to Sewer District 1 households with an explanatory letter and pushed the payment deadline from May 20 to June 30 to give people time to absorb it.
The town hired the consulting firm Raftelis that December to figure out what the rates should actually be. Their study, presented in the fall of 2025, found the town's water infrastructure was straining under real problems: 45 water main breaks per 100 miles of pipe in 2024, against a national median of nine. That is not a rate design issue. That is an aging system, and it is part of why any new rate structure was always going to cost more than the pre-2023 baseline, even after the political backlash.
By January 2026, Raftelis had a revised proposal on the table, one that dropped the flat minimum-usage charge in favor of billing closer to actual consumption. The town board voted on the new structure at its February 26, 2026 meeting, and the rates took effect this fall rather than showing up in spring bills. Here is what that arc looks like in dollars, for a low-volume household on a six-month cycle:
| Period | Six-month base charge (low-volume home) |
|---|---|
| Before 2023 | $30 |
| 2023 rate hike (still current through 2025) | $78 |
| New rate, effective fall 2026 | $62 |
An average-use Niskayuna home, defined by the town's consultant as using about 27,700 gallons over six months, is now looking at a combined water and sewer bill of roughly $373.81 for that period in Sewer District 1. Consultant Phil Sapone described the intent behind the redesign plainly when he presented it to the board: the new structure is meant to redistribute the cost between large and small users more fairly than the flat minimums did. That is a defensible goal. It also means the water and sewer figure printed on any listing prepared before this fall reflects a rate schedule the town no longer uses.
Same Street, Different Sewer District
The second wrinkle is one most buyers never think to ask about: which sewer district a specific parcel sits in. Niskayuna runs Sewer District 1 and Sewer District 6 on separate budgets and separate rate structures, and the two are not moving in the same direction. Sewer District 1's budget rose 17 percent for 2026, to $1.6 million, while District 6 rose 8.75 percent, to $5 million. Debt service, the portion of water and sewer costs that shows up on the property tax bill rather than the utility bill, was set at $0 for Sewer District 1 in 2026 while District 6 kept a reduced but nonzero debt charge.
None of that is visible from the street. A buyer comparing two similar homes a few blocks apart in Niskayuna can end up comparing two different billing systems without realizing it, because the base rates, the per-gallon charges after the readiness-to-serve fee, and the debt service line on the tax bill all depend on which district the parcel falls in. The only way to know for certain is to ask the seller's agent to confirm the district assignment or to call Niskayuna's water and sewer department directly with the parcel address.
The Tax Line Nobody Explains at the Walkthrough
The property tax figure carries its own version of the same problem. New York's STAR exemption reduces the school tax portion of a bill, but it belongs to the person, not the house. When a Niskayuna homeowner sells, their STAR exemption does not pass to the new owner. The buyer has to register separately with the New York State Department of Taxation and Finance, and because the STAR exemption itself is closed to anyone who did not already have it before 2015, most new buyers will receive the STAR credit instead, paid out as a check or direct deposit rather than as a line-item reduction baked into the bill.
That distinction matters more in Niskayuna than in a lot of towns nearby, because the underlying tax rate here already runs above the state norm. County assessment data compiled by property tax firm Ownwell puts Niskayuna's median effective property tax rate at 3.34 percent, with a median annual bill of $5,610, roughly $3,210 above the statewide median. On a bill that size, whether a specific STAR benefit shows up automatically or has to be applied for separately is not a rounding error. It is the difference between a tax number a buyer can budget around and one they discover after the first bill arrives.
Niskayuna's current assessment roll uses a valuation date of July 1, 2025, and the town's grievance window for challenging an assessment typically falls on the fourth Tuesday in May each year. Anyone buying now, after this year's window has closed, is inheriting the current roll until next spring's grievance period opens.
Before You Write the Offer
A few questions are worth asking before an offer goes in, or before a seller signs a listing agreement expecting the current utility bill to speak for itself.
- Ask which sewer district the parcel is assigned to, Sewer District 1 or Sewer District 6, since the rate schedules and debt service treatment differ between them.
- Ask for a full twelve months of water and sewer bills rather than a single statement, since seasonal usage swings the per-gallon charges significantly.
- Confirm whether the seller currently receives a STAR exemption, and if so, register for the STAR credit with New York State promptly after closing rather than assuming any tax benefit carries forward automatically.
- If listing a home for sale, note in the disclosure that Niskayuna's water and sewer rates changed this fall, so a buyer working from an older bill is working from a schedule the town no longer uses.
FAQ
Will my water bill be higher or lower than what the seller was paying? It depends on usage and district. Under the fall 2026 rates, low-volume households in Water District 1 see a lower base charge than they did under the 2023 to 2025 rates, but the per-gallon rate above that base charge changed too, so total cost still depends on how much water the household actually uses.
Do I need to do anything about STAR right after closing? Yes. Register with the New York State Department of Taxation and Finance as soon as the home becomes your primary residence. The benefit is not applied automatically based on the deed transfer.
What if I already closed on a Niskayuna home before the new rates took effect? The new rates apply to bills generated after the fall 2026 rollout regardless of when the home changed hands, so current owners will see the new structure on their next cycle whether they bought last year or last month.
