That is absolutely not true. If that was the case, EVERY airline would be in the ringer for not deducting from our checks properly. I may be based in CVG, but FL is where I live. That is where I pay taxes and my income tax reflects such, and H&R Block has been doing them the entire time I have had this job.

Not counting when you are flying, if you spend OVER half of the year at another residence (crashpad, rental, etc) out of your "home" state, then that would be considered your tax-home.
