This bill makes the following changes to the excise tax on motor vehicles.

1. The excise tax for a new or used vehicle is based upon the purchase price of the vehicle, as evidenced by the bill of sale or the sales tax document instead of on the maker's list price. This is the current practice for a commercial vehicle.

2. Except for a certain vehicle, such as a commercial vehicle or a motor home, the excise tax is due only once, when a person registers the vehicle. If that person remains the owner of the vehicle, the person is required to continue to register the vehicle, but no further excise tax is due.
