Nassau County 2026 General Tax Rates Explained: What Goes Into Your Property Tax Bill
Introduction
On January 2, 2026, Nassau County released the 2026 General Tax Rates for the 2025 - 26 tax year. These rates play a key role in determining how much homeowners ultimately pay in property taxes.
Understanding how these rates work - and how they interact with your assessed value - can help you better evaluate whether your tax bill is fair.
What Are General Tax Rates?
General tax rates are applied to your home’s assessed value, not its market price. Nassau County uses these rates to calculate the total amount owed across county, town, school, and special district taxes.
As explained in P.T.R.C., Inc.’s FAQ, even when tax rates remain relatively stable, changes in assessment values can significantly affect what homeowners pay year over year.
What Goes Into Your Total Nassau County Property Taxes?
1. School Taxes
School taxes typically make up the largest portion of a Nassau County tax bill. These funds support:
- School district operations
- Staffing and transportation
- Facilities, safety, and educational programs
School budget increases can impact homeowners even if their property assessment remains unchanged.
2. County Taxes
County taxes fund services such as:
- Public safety and courts
- Health and social services
- County infrastructure and administration
3. Town & Special District Taxes
Depending on location, homeowners may also pay taxes for:
- Fire and library districts
- Sanitation and water districts
- Park and community services
Each district sets its own rate, contributing to the total bill.
Why Your Property Taxes May Increase
P.T.R.C., Inc. frequently hears from homeowners who ask why their taxes increased even though they didn’t make major changes to their home.
Common reasons include:
- An increase in assessed value
- Rising school or district budgets
- Changes in neighborhood property values
As noted on P.T.R.C., Inc.’s Deadlines page, homeowners only have one opportunity per year to formally challenge their assessment.
Why Understanding Tax Rates Matters
Knowing how tax rates and assessments work together allows homeowners to:
- Identify possible over-assessments
- Understand sudden increases
- Decide whether filing a grievance makes sense
Many Nassau County homeowners qualify to file—even if they’ve never challenged their taxes before.
Final Thoughts
The release of Nassau County’s 2026 General Tax Rates is an important moment for homeowners to review their property tax situation.
