i think u wont. i bought my car used outofstate in ny and didnt pay ny tax. the dealer handled the paperwork to transfer to ct. i had to pay ct dmv the ct taxes. it wasn't included in the financing. so u may have to pay florida taxes if your buying to transfer to florida. i got a 30 day temp pass that allowed me to drive the car across the state to take into ct and had to get an emissions test. once that was done dealer forwarded all info to ct dmv along with the amount of tax ct told them.
