State tax filing

1. My wife and I were residents of CA until June 5 2021 when we move permanently to WA.

2. Yes we planned the move for a long time, changed our address, could not change DL until we were physically present in WA but we preapplied, we have friends and close family in WA, changed address with our bank etc.

3. Yes, we had a 2nd home in WA which was rented for a while. We thought we might live in it but decided to buy a new house instead and sell the old one.

4. So, no this was not a ploy to avoid CA tax. We have been here in WA ever since, moved our stuff in stages from CA and eventually sold our home in CA. You said that the gain is "not taxable in CA during the non resident period" Please clarify: not taxable by CA just for the non resident period? or not taxable at all since the sale took place while we were WA residents even though it was only for about 2 months? Thanks!
