I hear several years ago some pilots from another airline based in PHL won a legal suite against the IRS. They stated they only worked in the state from the time the reported for work until the left 3,000' which is federal airspace not owned by the state of Pennsylvania or the City of Philadelphia. I don't know how true the story is but you can always become a mail order minister and say your home is a church. All your pay check is deposited to the church account which you draw from for living expenses. Then convince your friends (other pilots) to join your church and give donations to your church which are tax deductible. The church would then buy all members of the church gift cards for gas, food, movies, etc as a show of appreciation for their attendance to his church in the exact amount of their donations.
