Capital Region
Nassau is a town in Rensselaer County, in New York's Capital Region region, home to about 4,500 people as of the 2020 census.
How Nassau works
Usually, the town is the local front door. The important exception is an address inside an incorporated village, where village and town responsibilities can split.
The Town of Nassau is a general-purpose local government. Its incorporated villages include East Nassau, Nassau. A village resident remains a town resident and taxpayer, while the village may add its own government, services, and tax line.
The building or zoning office decides what local approval a project needs. The assessor keeps value and exemption records. The tax receiver or collector handles the bill in hand. A single Town Hall page may route all three, but one record cannot answer for the others.
The current state tax-rate data connects Nassau with 4 school districts, including Averill Park, East Greenbush, New Lebanon, and 1 more. District boundaries can cross municipal lines, so the exact address decides enrollment and the school-tax part of the bill.
Town assessment and tax pages can show a parcel or owner, but the recorded deed and mortgage belong with the clerk for the parcel's county. Probate and administration normally follow the county where the person lived.
Ordinary example
The parcel is inside East Nassau. The homeowner checks whether the village or town owns the permit, uses the assessor named for the parcel, keeps the county deed record separate, and confirms the school district from the address.
Property tax snapshot
The state rows combine county + town + school district on a full-value basis (FY2025). On a $300,000 home that's about $4,950–$6,521 a year before STAR, exemptions, and special-district charges; an address inside a village can use different town/county rows and a separate village tax.
A planning estimate, not a bill. The exact address and school district decide the row. Confirm it with the assessor and current tax bill.
