how do i calculate the licence and title cost for used 2016 toyota tacoma
A dealer will do that for you as costs are variable depending on the dealer. Tax is a constant, and a certain percentage depending on your state. Also tag prices could be different. are you transferring one, a new one, etc. But you can calculate a ballpark number yourself, price of vehicle, minus trade, add tax and then add on a couple hundred on top of that.
Go to your states DMV website. You can probably do it there.
