What Is Residency? Can I Be a Resident of More Than One State? So there's different concepts to residency but the most common concept is from an individual perspective let's say you live in one state and you move to another state your residency changes and you know if you pick up and leave California and move to Texas and you never come back to California no problem the problem is is that people and businesses aren't usually that simple as a person can have multiple contacts with multiple states they might travel around they might live in several different states for a period of time and so residency is really where the tax home is for the tax payer and what residency really entails is an analysis of what's called domicile domicile is where you plant your flag it's where you set up your tax jurisdiction and the way that most state residency rules work is in order to sever residency with the state you got to pick up your flag out of state and plant it in another flag and there's a variety of factors that go into this but residency is a very complicated thing because well people say well can I be residents of two states and yes from a physical perspective you can be a resident of two states you can say I live in California and I summer in Colorado or you know whatever it is but the reality of the situation is with residency is even if you go back and forth between two states your domicile is in one of those states and one of those states has controlling jurisdiction over you you can't have a situation where you have to controlling jurisdictions so it's really important from a residency analysis to stop thinking about it from a where do I live perspective and start thinking about it from a tax perspective and that's where a lot of people get into trouble you.
