How each state structures it
Connecticut
Connecticut's vehicle costs are dominated by the annual motor vehicle property tax — billed by your town (Connecticut has 169 towns, no counties). State law CAPS the motor vehicle mill rate at 32.46 mills (effective FY 2022-23+), giving a maximum effective rate of 2.27% on depreciated MSRP. Most CT towns are at or near this cap. Sales tax is 6.35% on vehicles under $50,000 and jumps to 7.75% on the FULL amount for vehicles $50,000+ (a "luxury tax" cliff that surprises buyers). Registration is triennial $40/year annualized plus various state surcharges (Clean Air, Greenhouse Gas, Parks Pass) totaling about $27/year. Notably, Connecticut has NO EV registration surcharge. A new $35,000 vehicle in a typical CT town runs about $3,000 in first-year costs, with annual renewals around $815 in year 1 dropping to roughly $300 by year 8 as depreciation reduces the assessed value.
Rhode Island
Rhode Island's vehicle cost structure became significantly simpler when the long-criticized municipal motor vehicle excise tax was fully phased out by FY2023 (last bill issued was 2021). The state now charges only DMV registration (biennial, weight-based ~$45/year annualized) plus a $20/year DOT surcharge (raised from $15 in 2026) and a $27.50/year inspection fee. Sales tax is 7% state with NO local additions. RI does NOT charge an EV surcharge and offers up to $2,500 in EV purchase rebates. Title fee is $52.50. A new $35,000 vehicle in Rhode Island runs about $2,595 in first-year costs (dominated by $2,450 sales tax), with annual renewals around $92.
What this means for you
- Buying a new car: Rhode Island is roughly $472 cheaper than Connecticut in the first year on a $35K vehicle, driven mostly by sales tax and one-time fees.
- Annual renewal: Rhode Island is cheaper to renew annually by about $648/year. Over a 5-year ownership period that's roughly $3,239 in renewal-fee savings alone.
- If you drive an EV: Connecticut has no EV surcharge while Rhode Island adds $200/year — a meaningful long-term cost advantage for Connecticut EV owners.
- Structural differences: Connecticut charges an annual ad valorem property tax on vehicles (renewals stay expensive as long as you own the car), while Rhode Island does not — over a 10-year hold this can swing thousands of dollars toward Rhode Island.
