Buford is correct. First 90k or so is tax free...anything above that amount is paid at the tax rate of total income earned...for example, make 90k, you pay nothing; make 150k, first 90k free of tax, next 60k paid at tax rate of 150k, not 60k, which is very high, and due to go much higher next year. F/O does ok, Captain is taxed very high. Solution for Captain: stay home, or...get creative.
