Homeowners in Monmouth County, New Jersey pay a median of $10,001 a year in real estate taxes, on a median home value of $566,500.

What the Monmouth County numbers mean
The median is the midpoint of the county's actual bills: half of Monmouth County homeowners pay more than $10,001 a year and half pay less. The exact bill for any one home depends on its assessed value, exemptions, and which school, municipal and special districts cover it.
Set against the median home value of $566,500, the median bill works out to a derived effective rate of 1.76%. That rate is an estimate computed from the two medians — no county publishes a rate calculated this way — but it adjusts for home prices, which makes comparisons between counties more meaningful.

How the tax is worked out
The bill is built in stages. First the assessor puts a market value on the property. Exemptions — a homestead exemption above all — then reduce the taxable amount. Finally the combined local rate is applied. To see the scale: at the county's derived rate of 1.76%, each $100,000 of value corresponds to about $1,765 of tax a year, and a $400,000 home to roughly $7,060. Real bills use the official assessment and district rates, not this derived figure, so treat the example as a sense of scale only.
Checking your assessment in Monmouth County
Most successful appeals are won on facts, not arguments. Start with the property record card held by the Monmouth County assessor: wrong square footage, an extra room, or a missing homestead exemption are common and fixable. Next, line your assessed value up against recent sales of genuinely similar homes nearby. Many disputes end at an informal conversation with the assessor's office; if yours does not, file the formal appeal with the review board named on your notice before its deadline, evidence attached, and keep paying the bill in the meantime so penalties do not build up.
