Your Tax Bill

Hillsborough Township mails out third-quarter estimated tax bills each July. This estimated bill reflects the current year’s assessed value of your property. When calculating your total tax obligation, do not simply multiply the third-quarter amount by four, as this will not give an accurate estimate of your annual taxes, and will overestimate the true tax to be paid. Any adjustments to your total yearly taxes are reflected in the third and fourth quarter bills. Please keep in mind that assessed property values may increase, decrease, or remain the same from year to year based on changes in the real estate market. Since 2018, property market values have steadily increased which has significantly increased assessed values. The tax rate per $100 of assessed value has declined from $2.419 in 2018 to $2.143 in 2024 due to market trends and budgets increasing slightly resulting in minimal increases.The overall tax rate typically does not increase while on an annual reassessment program unless budgets have increased. 

Tax Allocation Note: It is important for property owners to understand how their tax dollars are distributed. For the 2025 tax year, only 14% of your tax bill funds municipal services provided by the Township. An additional 16% supports Somerset County services, 3% funds the local Fire District, and 1% is allocated to Open Space. The largest portion—a significant 66%—is directed to the Board of Education. As such, any substantial increases in your property tax bill are primarily driven by Board of Education budgetary needs and decisions, not by the municipal government.

There are several tax deductions and State rebate programs available. We encourage you to visit the Assessor’s webpage or contact the office to learn whether you may qualify. Website is as follows: https://hillsboroughnj.gov/departments/assessor or call directly 908-369-8077
