Do I need to file taxes for Oklahoma if my W2 shows two state codes under #15 CA & OK? My home state is CA but my job sent me to other states for work.
I worked for a company where I traveled all over the US remodeling stores. Never in the past did my company ever indicate another state that I worked in on my W2. For 2018 my W2 now shows CA and Ok under #15. Does this require me to say yes that I earned money in another state? And does this now require I file state taxes for OK?
