Informational notice

Figures describe the median homeowner household in Nassau County as reported to the Census Bureau; your parcel can differ. Not tax, legal, or financial advice: check the county assessor or a qualified professional before decisions that depend on these numbers.

The rate gave way faster than almost anywhere

Between the 2020 and 2024 releases the median home value in Nassau County rose 30.6%, from $524,400 to $684,700. The effective rate fell 23.4% over the same span, a steeper move than in 91% of U.S. counties.

The median bill still rose 0.0%, to $10,001. Where the rate drops this far and the bill rises anyway, what changed is the value the rate is applied to.

Effective rate is the published median bill divided by the published median home value, so the two multiply back to the bill exactly; the rate's movement here is derived from those two figures rather than read from the rounded published rate. Both are ACS 5-year survey estimates for the median owner-occupied household, compared across non-overlapping releases. They describe what the Census published, not a local policy, assessment, or exemption change.

How to read this county's bill

Very little moved here between 2020 and 2024: the typical bill went from $10,001 to $10,001, a change of 0%. The comparison describes county-level medians only; individual assessments and bills can differ.

The heaviest band is also the fullest one here: 349,346 of 375,466 owner-occupied homes (93.0%) report annual real-estate taxes above $3,000. That band has no upper edge in the source, so the county median understates the burden carried by the plurality rather than describing it.

Both figures are in the national top quarter, and the median bill still equals only 6.8% of median household income. A high rate on high earnings produces a large dollar figure, and only the dollar figure tends to get quoted; the ratio above is the other half.

The share above is the median annual bill divided by median household income, a ratio of two county-level medians rather than a household-by-household figure.

Nassau County's bill vs state & U.S. medians

Median annual bill bars around Nassau County's SPIKE ACS 2024 figure.

Nassau County $10,001
New York median $6,582
U.S. median $1,993

Nassau County's median bill is 52% above the New York median and 402% above the U.S. median.

Note: Census ACS top-codes median property tax at $10,000 or more, so the bill is shown as $10,001 and the effective rate above is a conservative floor - Nassau County's true median tax and rate are somewhat higher.

Same rate as New York, a larger bill

The effective rate here sits within 6% of the New York median, yet the median bill runs 52% above it. When the rate matches and the cheque does not, the difference is in what is being taxed, not how heavily: the same percentage applied to costlier housing produces $10,001 here. That is why comparing counties on rate alone can invert the answer a homeowner actually cares about.

Each row is a separate ACS 5-year release, and consecutive releases share four of their five survey years. The percentage beside each bill is therefore movement in the published estimate against the previous release, not a single year's tax change. The two releases largely describe the same households. For change over time, compare releases that do not overlap.
