General Information

Property tax bills are mailed annually in July and include 4 payment stubs. Taxes are due quarterly on February 1st, May 1st, August 1st, and November 1st.

Sewer rent bills are mailed annually in July and include 2 payment stubs. Sewer Rent is due semi-annually March 1st and September 1st.

Failure to receive a tax or sewer bill does not exempt you from paying or the interest due on taxes or sewer rent owed.

Grace period for Taxes & Sewer Rent: The Township grants a ten-day grace period, after which interest accrues from the first day payment is due. If the 10th falls on a weekend or legal holiday (or, on a day that the Tax Collector’s office is not open) the following business day will be the last day of the grace period. Please be advised that the State of New Jersey does not allow the Tax Collector to acknowledge postmarks.

Interest & Delinquencies: Payments received after the grace period will be assessed at 8% interest per annum on the first $ 1,500.00 of delinquency and 18% per annum on all balances over $1,500.00. Any balances over $10,000.00 on December 31st, will be assessed an additional flat 6% penalty. All taxes, sewer rent and municipal charges not paid by November 11 are subject to Tax Sale.

Mortgage Companies: It is your responsibility as a homeowner to let the Tax Collector’s office know if a bank is escrowing your taxes OR if the mortgage company will no longer be paying your taxes. If your property taxes are paid through your mortgage company, each quarterly stub will have a notation stating “Advice Copy Do Not Pay”

Ownership: When selling your property, the tax and sewer bill must be handed over to the new owner at the time of closing.

There are often times when the tax collector must return checks that are written incorrectly. These errors cause delays and necessitate interest being charged on late payments. Please double check the following when writing your check:

  • Check is made payable to West Windsor Township
    • Check is signed
    • The numeric amount matches the written amount
    • Check has a current date; postdated checks cannot be accepted
    • Include tax stubs for all properties that you are paying (If you do not have the stub, please include your block and lot number, tax account number, or your property location)
    • Include a self-addressed, stamp envelope for any information you require returned
    • Please do NOT staple your tax stub to your check
