Hello. I currently live and work in Wisconsin. I have a desire to move to San Francisco, CA, and continue working for the same employer (again, who is based in Wisconsin) by "telecommuting" from my home/apartment office in San Francisco. My apartment in California will not be an "official" company office/branch - it will just be where I physically work. I've been given tentative approval from my employer, pending figuring out the conundrum of state taxation; specifically, which state will I pay my taxes to? One? The other? Both? Half-and-half? How is this determined? Thank you very much for any help you can offer.
