Understanding Each State
Illinois

Florida
Florida has no state income tax, funded instead by a 6% state sales tax (plus local additions up to 2%) and property taxes. This makes Florida especially attractive for high earners and retirees. Florida's population has grown rapidly, partly driven by tax migration from high-tax states like New York and California.
