I have a single US employer. I believe they are already withholding my state taxes at this point as I submitted a w-9 with my address being in the US. I would prefer that not to be the case because my residency isn't really in the state of North Carolina anymore. I will be out of the country for at least 6 months, on tourist VISAs. Maybe even a year. Also, would I be subject to lower federal taxes (any credits)? All of my income has been earned in Thailand, none of it has been earned while I was in NC. I own no property there, have no vehicles or ID maintained there. I have a Drivers License from Maryland. The only connection I currently have is that I maintain an address there (my Mom's address) as mine.
The employer is not of NC, they are of another state.
Note: This is not freelance work, it is done on a W-9 with 1 company only.
