Supplementary Assessments

Supplementary assessments are done on newly constructed properties that are completed or occupied during the current year.

The supplementary tax is calculated on the increase in value from the annual assessment (prior year end value) to the value upon completion or occupancy and prorated based on the months the property was completed or occupied. 

Supplementary assessments and tax bills are mailed no later than October 31. Payments are due by December 31.
