Sales tax is owed in the state where the vehicle is titled and registered, not where you buy it. So if you live in Connecticut, crossing state lines to dodge Connecticut's 6.35% sales tax usually doesn't work — you'll still owe Connecticut tax when you register at home. The exception is when neighboring inventory and dealer pricing are meaningfully better; in that case, compare full out-the-door totals (including Connecticut tax) before deciding.
