I have a rotational job which requires me to frequently move to different states. a different state every 4 months. Additionally, my driver's license and parents live in Oregon, so I consider Oregon as my state of residence, but I didn't spend any time working there.
So in summary, I live in Oregon and this year will have have worked in New York, Connecticut, and Virginia.
Currently, I have a decent amount of profit from day trading and option selling. Last year, I only traded stocks and I traded at a loss. During tax time, I used TurboTax and Scottrade's import feature to automatically deal with all my trading taxes. When I did this, Turbotax imported all my trades into all the states I lived in. So it seems, all states tax credited (?) my trading loss.
This year I am primarily using Interactive Brokers, which does not allow auto import into Turbotax. So I am wondering how exactly my day and option trading activity will be taxed on the state level? Will all of the states I am involved in tax my trading activity? That doesn't sound right as I will pretty much lose all my trading profits to taxes. Shouldn't trades be taxed only in the closing state (e.g. if I buy back a profitable short option while I'm in VA, I should be taxed only VA)?
