Many states will tax you just for being based at their airport, regardless of whether you live there or not. Technically, you are supposed to file, but usually they just steal some money from your paycheck each month as "withholding" and never really expect you to file (I never have).

The danger here is that there is NO federal law that says you cannot be taxed by more than one state...each state has their OWN requirements for who has to pay, and it is VERY easy to meet those requirements in more than one state. Both states will probably want to tax your FULL income

Where pilots get into trouble, is when they show up as a big blip on the radar in their domicile state: These things will make the domicile state think you are a resident (in addition to the state you really live in):

- Register a car in domicile.
- Have a mailing address in domicile.
- Have a crashpad rented in your name, utilities, etc.
- Use public services.

You kind of have to fly low, because technically you probably spend enough time in your domicile state to qualify as a resident...they will consider all the time you spend on a trip that starts and ends in domicile as resident time.
