Agreed that you should speak to multiple accountants ASAP.

If you have made 6 months of W2 income in California, you are a tax resident there for ALL transactions occurring in 2018. Simply getting a driver's license in NV in August or something doesn't negate this.

If you haven't received any W2 income in California, then hm.... I think you could perform the transaction in Nevada.

Also, if you have bank interest or stock income in california, this is also impacting your tax residency.

Good luck and congrats!
