I guess your case was extra special. I remained employed by the same company after moving from CA to AZ and the FTB never bothered me. The year I relocated, I filed my.. 540? after determining what income I earned while living in CA. And that was that. No issues with my options or RSUs either. Being married and having a child was also a non-issue.
If you're married or have children AND they come with you to AZ, that's obviously no problem. In that case, it works in your favor: it's just more data that you're a bona fide AZ resident. I was pointing out that if your children stay in CA while you go to NV, it works against you.
And AZ isn't NV. The FTB pays special attention to NV in particular because it has no income tax. Someone who moves to AZ isn't so obviously trying to skirt CA state income tax.
My case was a little special because I sold a lot of stock right after leaving CA, which makes it a little suspicious to the FTB.
