Residency rules

How many days can you spend in each state?

Most states with an income tax call you a resident at 183 days, usually combined with having a place to live there. Some use a different number, some use no number at all, and nine states have no income tax to worry about. Pick a state for the exact rule.

Whereabouts helps you keep records. It is not tax or legal advice, and residency rules change. Confirm the rule for your situation with a CPA or tax attorney before relying on it.
