Hi
@doubleshot CA does not charge sales tax on subscriptions or on software licenses that are downloaded. So if you buy the $10K FSD license at delivery, you are charged tax since it was physically delivered. Also, the registration renewal is higher if purchased with the car. If it is licensed and download later it is not taxable in CA. The state has been very consistent on this issue for more than 20 years.
I have FSD on my order, but thinking of taking it off at delivery and then buying afterward (full license). But it may be that the license fee will go up by then. I wouldn't remove it until time of delivery though
