NOTICE: The Treasurers office will remain open until 5:00pm on 12/31/2025 for those who would like to pay their 2025 estimated Real Estate Taxes (payable in 2026) in conjunction with the increase in the State and Local Tax (SALT) deduction for 2025 federal taxes.

First half property taxes are due February 18th 
Should you pay your entire property tax bill? Or just the first half? 
The recommendation is tied to House Bill 186, which requires property tax rates to be recalculated for the second half of the year. That recalculation is expected to lower rates.
Given that HB 186 will require the recalculation of rates for the second half — and we expect the rates to decrease — it is advised to only pay the first half. The second-half bill will reflect a full-year adjustment once the new rates are finalized.
For property owners who have already paid their full balance, the Treasurer’s Office will notify them if they are owed a credit.
For property owners in the prepay escrow program you will be notified of the adjusted amount to be deducted based on the adjusted tax. 
Taxpayers may choose to apply that credit to their 2026 taxes, payable in 2027. If no response is received, refunds will be issued automatically.
Residents with questions are encouraged to contact the Treasurer’s Office for guidance.
