Frequently asked questions
What is the average property tax bill in Seaford?
The median residential bill is $12,020 per year ($1,002 a month). That is the median across 5,353 single-family parcels in the district. Individual bills vary with assessed value, location within the district, and any village or special-district levies that apply.
Why are property taxes higher in Seaford?
Long Island property taxes reflect three layered budgets: the school district (typically 60–75% of the bill), the town and the county. In Seaford, the school rate alone is $20.23 per $1,000 of full market value, one of the higher school rates on Long Island. Districts spend different amounts per pupil, carry different debt, and serve different home-value bases.
How do I lower my property tax bill in Seaford?
Two main paths. First, exemptions: STAR (every homeowner), Enhanced STAR (65+, income limit), senior, veterans and volunteer firefighter. Second, a tax grievance: if comparable homes nearby are assessed lower, file with your town’s Board of Assessment Review (Suffolk: third Tuesday in May; Nassau: by the March deadline). Grievance firms typically take 50% of the first year’s savings on contingency.
What’s a typical home value in Seaford?
The median single-family home in Seaford has a market value of $479,000 on the 2024 New York State assessment roll. The 10th to 90th percentile range is $399,000 to $607,000.
Is Seaford a good school district?
School quality is subjective. For objective measures, see the New York State Education Department’s official report card for graduation rates, test scores and per-pupil spending. We don’t rate schools here; we cover property tax only.

Methodology and sources
- Parcels and assessment values: NY State Office of Real Property Tax Services (ORPTS) combined parcel file, roll year 2025. data.ny.gov
- Tax rates: NY State ORPTS county, town and school combined rate file, roll year 2024. tax.ny.gov/research/property. The state publishes final rates a year after the fact.
- Median bill: for every residential parcel we compute a projected bill as full market value × combined county, town and school rate ÷ $1,000, then take the median. This handles districts that span several towns. Village, library and special-district levies are excluded because they vary parcel by parcel.
- District name and code: NY State ORPTS school-district reference file. For official enrollment, see the NYSED report card.
