Here's the Colts Neck tax story straight: the checks you write are large, and the rate behind them is one of the best in the county.
Per the NJ Division of Taxation's 2025 tables, Colts Neck's effective rate is about 1.49% of market value, against roughly 1.96% in Hazlet, 1.66% in Holmdel, and about 0.85% on Staten Island. On a $1.85M purchase, that's roughly $27,500 a year, versus about $15,700 at Staten Island's rate on the same value, and versus what the same dollars would cost in a high-rate town: a $1.85M property taxed at Hazlet's rate would run over $36,000.
Why the rate stays low: minimal commercial-services burden, a small school population, and a township that preserved land instead of building infrastructure to maintain. The farmland-assessment program also matters at the estate tier: qualifying agricultural acreage is taxed differently than the house lot, which is one reason working farms here carry better than their size suggests. That's a property-by-property analysis, and it's one I run before any offer at this level.
Monmouth's annual reassessment applies here like everywhere in the county: assessments track the market yearly, so budget the trajectory.
How we handle it: at this price tier, the tax line is a six-figure decision over a decade. I pull the actual bill, the assessment history, and any farmland-assessed acreage on every property you're serious about, before you fall in love.
