What is Supplemental Assessment?

The annual assessment notice reflects the condition of your property as of Dec 31 of the year prior to the current tax year. If construction is completed after Dec 31, you will receive a supplementary assessment and tax notice to reflect the respective increase in the assessed value of your property.

What is the Supplemental Tax?

The supplemental tax is determined by multiplying the supplemental assessment by the applicable tax rate, which is then prorated based on the number of months the new building has been completed or occupied during the current tax year.

Why does The Town have supplementary assessment and tax?

Supplementary assessment and tax contribute to the cost of municipal services, providing for the equitable sharing of these costs among property owners.

When is the supplementary assessment and tax notice sent out?

Supplemental taxes are levied only in the year the newly constructed building is complete or occupied. Supplementary notices are mailed between June and December, with the supplementary tax being required to be paid by the due date on the notice.
