Motor Vehicle Valuation Information

 
Effective with the October 1, 2024 Grand List, Assessors statewide will utilize the Manufacturer Suggested Retail Price (MSRP) of your vehicle, and apply a statutory depreciation schedule to calculate the depreciated value of your vehicle. The South Windsor Town Council adopted a modified depreciation schedule as of March 17, 2025 (HB 7067), see chart below.
 
The depreciated value will then be multiplied by the statewide assessment ratio of 70%, producing the assessed value of your vehicle for taxation.
 
The assessed value of your vehicle will automatically decrease according to the depreciation schedule. Your vehicle will be assessed at no less than 500 for taxation purposes at any time.
