Supplementary Tax
A supplementary tax bill is issued upon the completion or occupancy of a new improvement to a property during the current calendar year. This tax is determined by the increase in property value, from the annual assessment (prior year-end value) to the value upon completion or occupancy.
The supplementary tax is prorated from the time of completion or occupancy to the end of the current calendar year. Supplementary tax notices are mailed in the Fall, and payment is required within 30 days of the mailing date. Any payments made after the due date will be subject to penalties.
