By state law, every real estate property is revalued at least every five years. The most recent town revaluation was in 2015. Revaluations may occur within a year due to (a) new construction, (b) splits, (c) mergers, (d) demolition or (e) change in use. New construction includes ground up new construction, additions and extensive renovations. Depending on the degree of renovation, a new valuation may or may not be warranted, as determined by the town appraiser.

Taxes due are determined using a mill rate, or one thousandth of one percent of the assessed value. Mill rates are determined in May of each year. Current mill rates are 11.369 for homes with septic fields and 12.018 for homes serves by public sewer. As an example, a home valued at $2,000,000 would have an assessed value of $1,400,000. If on sewer, the property taxes due would be $1,400,000 x .01218 = $16,825 / year. Waterfront properties incur an additional tax based on lineal feet of waterfront. Some properties may be subject to additional taxes based on their association or neighborhood to reflect additional services. Property taxes are billed July 1st (due August 1st) and January 1st (due February 1st).
