I am helping my boyfriend with his 2023 taxes. He is an over-the-road truck driver who lives in MN and worked in MN the first half of the year, but took a job mid-2023 with a company located in Sacramento, CA. Sacramento is their hub/shop and where he was dispatched out of. His W-2 lists the Employer's address as Sacramento, CA. However, the W-2 lists Illinois in Box 15. (Apparently, they process payroll out of an office in Illinois). So, in addition to MN, which state does he file incomes taxes in - California or Illinois? I need to know which state to purchase on Turbo Tax.
