The question is, are you a resident of Wisconsin for state income tax purposes?
Maybe. See this.

You have only one domicile at a time. Your domicile is your permanent home. There is no single factor that determines, but factors include where your significant income sources, friends, doctor and dentist, church and other social organizations, voter and driver registration, and so on, are located. Part of establishing a new domicile requires taking affirmative steps to abandon your old domicile.
If you still have ties to Wisconsin and consider it your home state, you are probably still domiciled in Wisconsin; if it is your domicile, then you owe a state resident income tax return on all your worldwide income, even income earned while living outside of Wisconsin.
If you effectively abandoned your Wisconsin domicile, and were domiciled in Florida, then you don't owe Wisconsin state income tax. It's possible for a short term move to be a real change of domicile, but this is harder to prove. It really depends on the facts of your specific situation.
