I live on the East side of the state (Richland, WA 99354) where I believe sales tax on cars is 8.9% (2.1% local rate, 6.5% state rate, additional use rate of 0.3%) but we don't have any Tesla dealers here. The Tesla store who I've been talking is located in Seattle and they seem to have a 10.1% tax rate. It's not a huge difference, but based on the cost of the car it's worth a difference of about $517. I'm also 205 miles away from the University Village Tesla store (who I've been talking to). If I order online at Tesla.com will they calculate and apply the vehicle tax based on my address where I live (the 8.9% rate), or will it be calculated based on a delivery store location? Can I have the car delivered to my home without an additional charge? I original was told on the phone I could since I was far enough away, but a different sales rep is saying I have to come pick it up...
