Tax Department

Tax Collector

The Tax Collector is responsible for collecting all property taxes. Upon receipt of the Township’s tax assessments and certified tax rate, tax bills are calculated and mailed to property owners, authorized banks and mortgage companies.

When property taxes are not paid on a timely basis, the Tax Collector is responsible for delinquent billing and schedules an annual Tax Sale to collect delinquent taxes.

The Tax Collector strives to obtain a high collection rate to minimize a negative budgetary impact on the Township’s financial expenses. The Tax Collector provides written reports to both the governing body and the State of New Jersey.

Stillwater Township now offers On-line payments via credit card or e-check. 

Note: Tax bills are mailed out once a year, usually in July.

Taxes are due: Feb. 1, May 1, Aug. 1, and Nov. 1. Each quarter has a 10-day grace period, and interest accrues after the grace period, from the due date. Added Assessment bills for improvements are mailed out in early October each year and are due Nov. 1st.

Homestead Rebate Benefit Application News


Because the COVID-19 pandemic is anticipated to negatively impact the State economy, the New Jersey Department of the Treasury has frozen a portion of spending in order to ensure the State can meet its emergency and statutorily required obligations. Regrettably, this includes freezing funding to support the 2017 Homestead Benefit program.As a result, any credits intended to be applied to the May 1st property tax bills, including checks or direct deposit to homeowners who previously sold their home, or owners of continuing care and co-op facilities, can no longer be supported by the State at this time. We empathize with homeowners who depend on these credits, but these proactive steps are necessary at this time. Please continue to check Taxation’s website and Treasury’s homepage for updated information.

The Deadline to File the Latest Homestead Benefit Application for Tax Year 2017 was December 2, 2019.

The Homestead Benefit program provides property tax relief to eligible homeowners. For most homeowners, the benefit is distributed to your municipality in the form of a credit, which reduces your property taxes.

Property Tax Relief Information

There are two levels of property tax relief in New Jersey, programs administered at the Municipal level, and those that are administered at the State level.

Municipal Level
The two programs administered at the Municipal Level are the Senior Citizens’ Deduction and the Veterans’ Deduction. Both give the homeowner a $250 credit on their taxes, beginning in the year that it is first approved. The Veteran’s deduction continues without any annual verification necessary until the Veteran sells the home. If a veteran dies while the deduction is in effect, his or her spouse will receive the Widow of a Veteran unless they marry again. The Senior deduction is based on income, so each year a verification form is mailed out to all the seniors with the deduction, wherein the senior must certify that their income did not exceed the amount allowed in the prior year, and that they believe that it will not exceed the amount in the subsequent year.  (Income other than Social Security and other Federal programs must not exceed $10,000.)

State Level
All other property tax relief programs are administered by the State of NJ: Homestead Rebate Property Tax
