Hello JA Customer,
Regardless of whether you consider yourself still a resident of WA state or a resident of GA, you would still owe GA state taxes on income you earn from physically working inside of that state's borders.
State taxes are due in the following instances:
1. All income is reported from all sources to your resident state (assuming that they have a state tax, and
2. Any income you have from a state where you physically work is reported to the state where you work, and that's state income tax applies to that income.
Normally the way it would work if you reside in one state but live in another is that you would file a nonresident return with the state where you work and report your income from that state and pay taxes on that income. You would then file a return with your resident state and report all income earned from all sources, but your resident state would then allow you a credit for the taxes paid to the other state.
In a situation where you reside in a state that does not impose a state income tax, then there is no resident return to file and no credit to apply. When you reside in a state that has no income tax, you lose the benefit of not owing state taxes on your earned income, when that earned income is from a state other than where you live and work.
Thank you JA Customer
