I lived and worked in Washington state for the most of 2014. At the very end I moved to California on the 28th of December, so technically I lived three days in the state of California (being unemployed at that time). In Washington I do not need to pay a state tax, but do I need to pay state tax for these 3 days in California?
No, you only pay tax on money you earned while in the state in question. Even then generally there are exclusions if you made only a small amount. (Generally earning less than $400 or $500, depending on the state, relieves you a having to file or pay taxes in a state.)
Don't want to pay any state income tax? There are seven states with no state income tax. They are Alaska, Florida, Nevada, South Dakota, Texas, Washington and Wyoming.
Yes, I am a CPA.
