I'm a long-time California resident. But in 2024, I spent ~5months outside the US. During those months, I started a new job, working for a big company, which is headquartered in California, but I joined a team based in Massachusetts. I was supposed to eventually move to MA, but after my return to the US (and California), I continued working remotely for a few more months, and then I changed teams and joined a team that was local in CA.
For the 5 months that I was outside the country and was working with a MA-based team, should I be paying tax to California, to Massachusetts, or to neither of them? I was never a MA resident.
