The first step would be to contact the Assessor’s office to ensure that the vehicle descriptive data is correct and that the assessment was correctly applied. If this does not resolve the issue, then you may present your argument before the Board of Assessment Appeals (BAA).
The BAA convenes twice per year, in September and March. The September hearings are for Motor vehicle appeals (only) and are “walk-In” on a first come first serve basis. During the March hearings the BAA hears arguments for all types of taxable property (motor vehicles, real estate, and personal property) and are by appointment only. Please contact the Town Clerk's Office at 203-287-7112 to get exact dates. Application forms to appear before the BAA will be available in the Assessor's Office in January, and must completed and returned to the Assessor's Office by February 20th, or the business day prior to February 20th if the 20th is a week or a holiday.
Application forms may be downloaded by visiting the Board of Assessment Appeals Forms page.
