From the town eblast I got today:
"Tax Collector: The Tax Bills were mailed from our Printing Company on Monday, December 5, 2022. Please be advised that amounts will be posted online no later than Thursday, December 8, 2022. The due date for the 2nd Half Real Estate Taxes is January 11, 2023. Should you have any questions, please contact the tax office."
The kiosk seems to have the bill; at least mine seems to be correct, including the veteran's discount.
