State officials don't have the legal authority to force a town to reassess its property values, but a lower equalization rate can lead to reductions in state aid for local school districts. State government also has an incentive program that gives towns $5 per parcel to keep records up to date. In Niskayuna, with 8,371 properties, that's nearly $42,000 a year.
Niskayuna is just the latest in a series of local towns that have examined its tax rolls in the light of soaring residential property values and out of date records. Last year neighboring Rotterdam narrowly approved a controversial revaluation believed to be the first in that community's history. Recently New Scotland and Bethlehem, two suburban towns in Albany County, have also encountered the ire of local homeowners after revising their tax rolls.""
