i'm not familiar with tax policy in a lot of states, but i know that oregon has no sales tax. therefore, i was wondering, let's say i lived in oregon and bought a car there. then a few months (or years, or whatever) later, my job required me to relocate to, let's just say California to make it easy. what is the policy on the sales tax i never had to pay when i purchased the car in oregon?
and if there's no penalty, what's to stop someone from going up to oregon, purchasing a car there, and driving it back here to california and changing the registration (assuming you had a friend who lived in oregon who was willing to let you use his address for registration purposes)?
i'm just curious to know what kinds of policies are in place to prevent this kind of thing (because i assume that such policies must exist).
