I am completing my IL state tax now but not sure how to treat it when I work in IL and my company is in IL but I live as many days in FLorida but do not earn any income in FL. I am a registered voter in FL, my car is registered in FL but I own a home in both states. My wife is in FL full-time and also works in FLorida. I assume all my income earned is taxed in IL, what about my dividends, interest earned, etc?
