My home is in MA. I worked on a temporary business assignment in California for about 2.5 years at a customer location. For 2020, I was finishing up my California business assignment and left CA in September. Then, I went on another business assignment (customer location) to Virginia for the remainder of the year. However, home is still MA to me. How should I file my state taxes? Should I file as a California resident since I was there for 2.5 years even though MA is still home to me? For the last part of 2020, should I file as a MA resident and VA non-resident? My work department is based out of MA the entire time. I went on travel to work with customers in CA and VA. My tax accountant filed me as a CA resident for 2019 taxes based on the CA physical presence of over 365 days. For 2020, should I file as part-year CA resident, part-year MA resident, and VA non-resident?
