If you are smart enough to be a professional pilot (not a that high a bar really), you are smart enough to knock out your own full tax returns, or at least do them with Turbo Tax or some other program for under $50. An extra $300 for one more form is robbery. $300 for everything is robbery unless you have your own business that needs to be all accounted for on top of the pilot stuff. All the instructions for every form are provided on the IRS website, right next to the forms you have to fill out. If you need a template, insist on a copy of every form that your accountant fills out for you this year so you can do it yourself next year. I was shocked how easy it is when I had to figure it out myself while I was a poor flight instructor with no money for even Turbo Tax.
