Until a total Grand List, including all new values, is completed, and a new budget is adopted, no one can say what the mill rate or your tax bill will be.
A fact to consider, however, is that with the downward or upward adjustment of the mill rate at revaluation, the tax bill on motor vehicles could increase or decrease. Remember since the 2011 revaluation the real estate assessments have been 70% of 2011 market value, and have remained that way for the past five years until the 2016 revaluation. But this is not the case for motor vehicles. A motor vehicle is annually assessed at 70% of current average retail value. When the mill rate is reduced, one will pay less in Shelton on motor vehicles. When the mill rate increases, one will pay more.
In other words, consider the total municipal tax bill – real estate and motor vehicles – and then look at the impact of revaluation.
