Therefore, if you have literally lived in CA the past 3 years as you stated, all your income for those 3 years is taxable by CA, and you would have to file in CA as a resident. The state of your vehicle registration or drivers license doesn't matter.
Another thing to be aware of is that any income your husband had from working in CA would taxable by CA - regardless of his state of residence. If it were the case that he were not a resident of CA, he'd have to file in CA as a non-resident, and pay CA income tax on that income.
Finally, if you moved to NV during 2019, you would file your 2019 CA return as a part-year resident.
