Retirement tax questions

Where is your domicile, your permanent residence?  If your permanent home is WV, then all your income is taxed in WV no matter where you are living when it is paid.  It is possible for your permanent home to be in one state even if you spend a long time in another state.  You would also owe a non-resident tax return to VA, and WV will give you a credit against BA tax you paid on the same money.  

Ask for more details if you are a resident of WV.
