About Property Taxes in New Jersey

New Jersey consistently ranks as one of the highest property tax states in the country, with an average effective rate above 2% of market value — among the highest of any state. Property taxes in New Jersey are administered at the municipal level, meaning each of the state's 564 municipalities has its own tax assessor setting values and its own tax rate. Unlike most states, New Jersey collects property taxes quarterly. This spreads the burden across the year but also means there are four due dates to track rather than one or two. The state, county, and local governments all depend heavily on property tax revenue, which funds a significant share of public school costs.

Payment & Assessment

New Jersey property taxes are billed and due quarterly: First quarter: February 1 Second quarter: May 1 Third quarter: August 1 Fourth quarter: November 1 A 10-day grace period applies to each quarterly payment, meaning no penalty is assessed until February 11, May 11, August 11, and November 11 respectively. Late penalty: 8% per year on the first $1,500 of delinquent tax; 18% per year on any amount over $1,500. Additional charges apply if the delinquency exceeds $10,000 at year-end. August and November bills are typically estimates based on the prior year's tax while the new assessment is being finalized. If your actual annual tax is higher or lower than estimated, the difference is reconciled on the next quarterly bill. Most municipalities offer online payment through the municipal tax collector's website. Payment by mail and in person is also available.
