This is up to the dealer. Some dealers are required by their state to collect sales tax on all Internet transactions. Most states however only require sales tax to be collected if the buyer is in a state in which the seller conducts business. A seller may have their store in one state, but have warehouses in other states. The dealer would be required to charge tax for all sales within these other states also. For more info, please contact each dealer individually before your purchase.
