He was transferred to NV from CA.  Before the transfer in 2022 he was a longtime CA resident.

3-week Visit = vacation.

I know the income source rules.  He completely moved to NV due to the transfer and performs his work after the transfer 100% in NV . 

I just wonder, when a non-resident is issued a CA W-2, what would be the best way to report.  I still think 2022 part-year resident and 2023 2024 and 2025 non resident returns would be logical.

HR says because the budget is from the CA branch, the W2 has to show CA, and employee has to take care of the tax reporting. Technically, the nature of the work would not prohibit an employee from perform some work in CA except that Client completely moved to NV - sold the CA house, bought a (bigger) house in NV, registered the car and driver's license in NV etc.

Can't argue with internal policy of the organization, or HR.
