I live in CA and work for a company based in MA. I travelled and worked in MA about 60 days last year. I believe (but correct me if I'm wrong) that I will need to pay MA state income taxes for those 60 days (based on a daily salary calculation). Can I also adjust my CA taxable income by the same amount? If not, that seems like both states are taxing me on my daily salary when I am in MA.
