If you live in one state and work in another state; that income is subject to taxation by both states. This is how it works (in most cases): You file a nonresident return for the state you worked in, reporting only the income you earned there.
You report all your income on your resident state return, including the income earned in the other state. Your home state calculates tax on all your income, but gives you a credit, or partial credit, for tax you paid to the other state.
When you worked in a state without an income tax (e.g. Texas or Florida), there will be no credit, since there was no FL tax. In other words, having worked in a state without an income tax does not get you out of paying state tax on that income, to your home state
