Property tax in Nassau County, New York
In Nassau County, the property tax bill comes from the Receiver of Taxes in your town (Hempstead, North Hempstead or Oyster Bay); in the cities of Glen Cove and Long Beach, the city. The 2026-2027 school taxes and 2027 general bill is paid in 4 installments, and the next one is due November 10, 2026. Taken from Nassau County's own pages, checked September 23, 2026.
The median property tax bill in Nassau County, New York is $10,000+ a year, which is at least 1.46% of the county's median home value of $684,700. The Census stops counting at $10,000: it reports only that the median bill here is $10,000 or more, so the true bill and rate are higher than shown. That effective rate is higher than the national median (0.81%); against the typical New York county (2.04%) the capped figure cannot say. These are American Community Survey 5-year estimates (2024); your own bill depends on your home's assessed value and any exemptions.
Who sends the property tax bill in Nassau County, and how do you pay it?
The bill comes from the Receiver of Taxes in your town (Hempstead, North Hempstead or Oyster Bay); in the cities of Glen Cove and Long Beach, the city. The value it is based on is set by a separate office, the Nassau County Department of Assessment (the cities, and villages that keep their own rolls, also assess for city and village taxes), which is who to ask if the value looks wrong.
Nassau County homeowners get two separate bills a year from their town's Receiver of Taxes: a school tax bill in October and a general tax bill (county, town and special districts) in January, each payable in two halves. Village residents also get a village tax bill, and in Glen Cove and Long Beach the city sends the bills. The county, not the town, sets your assessment, and appeals go to the county's Assessment Review Commission, well over a year before the bill that uses that assessment. Each town runs its own online payment site; the county Treasurer's online payments are for delinquent taxes only.
When are property taxes due in Nassau County?
For the 2026-2027 school taxes and 2027 general (county and town) taxes bill, Nassau County splits the bill into 4 payments, the first due November 10, 2026 and the last August 10, 2027. Each half has a 40-day penalty-free period. Miss it and the penalty is counted from the original due date at 1% a month, so a payment the day after the deadline already carries 2%. Mailed payments count by the U.S. Postal Service postmark; an office postage-meter mark does not count, and the penalty cannot be waived. The Postal Service now postmarks mail on the day it is processed at a regional facility, which can be later than the day you mail it, so do not mail at the last minute. Town receivers take school taxes through May 31 and general taxes through August 31. After that, unpaid taxes must be paid to the Nassau County Treasurer with added charges, and the county sells liens on taxes still unpaid.
| Payment | Due | Note |
|---|---|---|
| First half 2026-2027 school tax | November 10, 2026 | Due October 1, 2026 and payable without penalty through Tuesday, November 10, 2026. School taxes come on their own bill, separate from the general tax bill. |
| First half 2027 general tax (county, town and special districts) | February 10, 2027 | Due January 1, 2027 and payable without penalty through Wednesday, February 10, 2027. When the 10th falls on a weekend or holiday, the last day to pay without penalty is the next business day. |

On top of the New York programs, Nassau County runs its own:
- Volunteer firefighter and ambulance worker exemption: Homeowners enrolled for at least two years in a volunteer fire company, fire department or ambulance service that serves their city, town or village may get an exemption of 10% of the assessed value of their primary residence, and Nassau County makes it a lifetime exemption after more than 20 years of service. Whether it also reduces city, village or school taxes depends on whether that government opted in. Apply to the Department of Assessment with a letter of certification from the department and proof of residency; city and village residents also file with their local assessor.
