How High Are Property Taxes in Nassau County Compared to Other Parts of Long Island and What Should I Budget For

Nassau County consistently ranks among the highest-tax counties in the entire United States. That is not an exaggeration. According to data compiled by Forbes and Bankrate's property tax research, New York State as a whole has one of the highest effective property tax rates in the country, and Nassau County sits near the very top of that list. The county's effective rate has historically hovered between 1.8% and 2.2% of a home's market value, depending on the municipality and the specific tax year.

Nassau vs. the State Average

New York State's statewide average effective property tax rate is roughly 1.54%, which already places it among the top five states nationally. Nassau County's effective rate lands well above that figure. On a $700,000 home, a 2% effective rate produces an annual tax bill around $14,000. That same home in Westchester County, another high-tax New York county, might carry a comparable bill, but in many upstate New York counties the bill on the same home could be half that amount.

How Nassau Compares to Suffolk County

Suffolk County, which sits directly to Nassau's east and includes towns like Babylon, Islip, Brookhaven, and the East End, generally carries lower effective property tax rates than Nassau. Suffolk's effective rate typically falls in the 1.5% to 1.9% range, depending on the specific school district and village. That gap matters enormously in dollar terms. On a $600,000 home, the difference between a 1.6% Suffolk rate and a 2.1% Nassau rate is $3,000 per year, or $250 per month added to your housing cost. Buyers comparing towns on the Nassau-Suffolk border, such as Massapequa Park versus Amityville, should pull the actual tax bills on comparable properties rather than relying on county-level averages.

2. How Property Taxes Are Calculated in Nassau County

Nassau County's property tax system is layered and can be confusing at first glance. Your total annual tax bill is not a single charge from one authority. It is the sum of levies from multiple taxing entities, each applying its own rate to an assessed value that the county assigns to your property.

Assessed Value vs. Market Value

Nassau County assesses residential properties at a fractional percentage of their market value, not at full market value. The county uses an assessment ratio, and the Nassau County Department of Assessment publishes the equalization rates annually. As of 2026, Nassau County assesses Class 1 residential properties (one, two, and three-family homes) at roughly 0.1% of market value, and then applies a tax rate per $100 of assessed value. The math can look strange until you work through both numbers together. The key figure to look at is the total annual tax dollar amount shown on the property's current tax bill, not the assessed value alone.

The Role of Tax Classes

Nassau County divides properties into four tax classes. Class 1 covers most single-family homes, two-family, and three-family residences. Class 2 covers apartment buildings. Class 3 covers utilities. Class 4 covers commercial property. If you are buying a single-family home in Garden City, Rockville Centre, Manhasset, or any other Nassau community, you will almost certainly be in Class 1. The rules for how Class 1 assessments can increase year over year are capped, which is one reason why longtime owners sometimes pay lower effective rates than new buyers purchasing at today's prices.

How the Three Tax Layers Stack Up

Your Nassau County tax bill combines three separate levies. The county general tax funds county-wide services including the Nassau County Police Department, which is one of the largest municipal police forces in the country. The town or city tax funds services at the local municipal level, whether that is the Town of Hempstead, the Town of North Hempstead, the Town of Oyster Bay, the City of Long Beach, or the City of Glen Cove. The school district tax is typically the largest single piece of the bill, often representing 60% to 70% of the total annual amount. Special district charges for fire, water, sanitation, and lighting are added on top of those three layers.

3. Town-by-Town Property Tax Ranges Across Nassau County

Nassau County's three towns and two cities each have their own tax structures, and the school district you fall into within each town can shift your bill by several thousand dollars per year. The ranges below are based on typical single-family homes at current market prices. Always pull the actual tax bill from the Nassau County Department of Assessment's public records for any specific property before making an offer.

Town of Hempstead

The Town of Hempstead is the largest town by population in New York State and covers a wide swath of southern and central Nassau County, including communities like Valley Stream, Rockville Centre, Oceanside, Freeport, Merrick, Bellmore, Wantagh, and Levittown. Annual property tax bills on single-family homes here vary considerably by school district. A three-bedroom cape in Levittown with a market value around $550,000 might carry an annual tax bill between $10,500 and $13,000. A comparable home in Rockville Centre, where the school district levy is higher, could see a bill between $14,000 and $17,000. The southern communities along the South Shore, including Long Beach Road corridors and the Five Towns area, also tend to carry higher bills because of the combination of village taxes and school district levies.

Town of North Hempstead

North Hempstead covers the North Shore communities including Great Neck, Manhasset, Port Washington, Roslyn, and New Hyde Park. Homes here tend to carry among the highest tax bills in the county because market values are higher and the school district levies are substantial. A four-bedroom colonial in Manhasset priced around $1.2 million can carry an annual tax bill between $20,000 and $28,000. In Great Neck, a similar home in the $900,000 to $1.1 million range often sees bills in the $18,000 to $24,000 range. Port Washington properties at comparable price points tend to run in a similar band. If you are exploring a purchase in any of these communities, Wilson Vernelly's article on buying a home in Manhasset covers what buyers should know about navigating this market, including the tax picture.

Town of Oyster Bay

The Town of Oyster Bay spans the central and eastern North Shore, covering communities like Syosset, Plainview, Hicksville, Massapequa, Bethpage, and Oyster Bay Cove. Tax bills here are generally somewhat lower than in North Hempstead for comparable home values, though still well above national averages. A four-bedroom home in Syosset priced around $850,000 might carry an annual tax bill between $14,000 and $18,000. Bethpage and Plainview at similar price points often fall in the $12,000 to $16,000 range. The Massapequa communities along the South Shore of Oyster Bay can see bills from $11,000 to $15,000 on homes in the $550,000 to $750,000 range.

City of Long Beach and City of Glen Cove

Long Beach, the barrier island city on Nassau's South Shore, has its own city tax structure separate from the three towns. Condominiums and single-family homes in Long Beach often carry annual tax bills between $8,000 and $16,000, depending on unit size and assessed value. Glen Cove, on the North Shore, is a city with its own tax levy. Single-family homes in Glen Cove in the $600,000 to $800,000 range frequently see bills between $13,000 and $19,000. Both cities have their own fire and sanitation structures that factor into the total.

4. What Should You Actually Budget for Property Taxes in Nassau County

The practical budgeting answer for Nassau County property taxes is this: plan for 1.8% to 2.3% of the purchase price per year as a starting estimate, then verify the actual bill on the specific property. That range accounts for the variation across school districts and municipalities. Use it to set your initial budget, and then refine it once you have the property's current tax bill in hand.

Typical Annual Tax Bills by Price Range

These are illustrative ranges based on current Nassau County market conditions in September 2026. They are not guarantees, because the school district and specific municipality matter enormously. Think of them as a planning floor and ceiling.

• Homes priced $400,000 to $550,000: Annual tax bills typically range from $8,500 to $13,000. These are often smaller capes, ranches, and older colonials in communities like Elmont, Franklin Square, New Hyde Park, and parts of Levittown.
• Homes priced $550,000 to $750,000: Annual tax bills typically range from $11,000 to $16,500. This bracket covers a large portion of Nassau's housing stock, including expanded capes and four-bedroom colonials in Wantagh, Bellmore, Massapequa, and Bethpage.
• Homes priced $750,000 to $1,000,000: Annual tax bills typically range from $14,000 to $22,000. This range covers many Rockville Centre, Syosset, and mid-range North Shore properties.
• Homes priced $1,000,000 to $1,500,000: Annual tax bills typically range from $18,000 to $30,000. This covers higher-end colonials and expanded homes in Manhasset, Garden City, Great Neck, and parts of Oyster Bay Cove.
• Homes priced above $1,500,000: Annual tax bills can range from $25,000 to $50,000 or more. Estate properties in Old Westbury, Muttontown, and the North Shore Gold Coast communities can carry bills at the high end of this range.

Monthly Escrow Impact

Most lenders will require you to escrow property taxes as part of your monthly mortgage payment. If your annual tax bill is $15,000, your lender will collect $1,250 per month on top of your principal and interest payment. On a $700,000 purchase with 20% down at a 6.5% rate over 30 years, the principal and interest payment is roughly $3,530 per month. Add $1,250 in tax escrow and another $150 to $250 for homeowner's insurance escrow, and the total monthly housing cost approaches $5,000 to $5,100. That is the real number to stress-test against your income before you make an offer.

Exemptions That Can Reduce Your Bill

Nassau County offers several exemptions that can meaningfully reduce your annual tax bill. The Basic STAR exemption is available to homeowners who use the property as their primary residence and is administered through the New York State Department of Taxation and Finance. Enhanced STAR provides a larger reduction for homeowners 65 and older who meet income thresholds. Veterans exemptions are available for qualifying honorably discharged veterans. The Senior Citizens Exemption provides a reduction based on income for residents 65 and older. The Clergy Exemption applies to active clergy members. Each exemption has its own application deadline and eligibility rules, so check with the Nassau County Department of Assessment directly for current figures and filing dates.

5. How to Challenge Your Assessment and Potentially Lower Your Taxes

Nassau County homeowners have the right to challenge their property assessment every year, and a successful grievance can reduce your annual tax bill permanently until the assessment changes again. This process is called filing a grievance, and it is more common in Nassau County than almost anywhere else in New York State because the county's assessment history has been contentious and many homeowners have successfully reduced their bills.

The Grievance Process

The Nassau County Assessment Review Commission (ARC) is the body that hears grievance applications. You file a complaint form arguing that your assessed value is higher than it should be relative to your home's market value. The strongest evidence is recent comparable sales of similar homes in your neighborhood that sold for less than the value implied by your assessment. You can file the grievance yourself at no cost, or you can hire a tax certiorari attorney who typically works on contingency, meaning they take a percentage of any tax savings you receive. There is no fee if you are not successful.

Deadlines and What to Expect

Nassau County publishes a tentative assessment roll each January, and the grievance filing deadline is typically in late March of the same year. The ARC then has until March 31 of the following year to issue its determination. If the ARC denies your grievance or does not reduce the assessment enough, you can escalate to Small Claims Assessment Review (SCAR) in the New York State Supreme Court, which is a relatively informal process designed for individual homeowners. Many Nassau County homeowners file grievances annually as a matter of routine, particularly in the years following a home purchase, because a new sale price can sometimes trigger an upward reassessment.

If you are currently working with Wilson Vernelly to buy or sell a home in Nassau County, asking him to pull the full tax history and any pending grievance status on a property you are considering is a standard part of due diligence. A property where the seller has a long-running grievance may see its assessed value adjusted after the sale closes, which can affect your tax bill in either direction.

Whether you are buying your first home or selling a property you have owned for years, understanding how Nassau County property taxes compare to the rest of Long Island is essential to making a sound financial decision.
