There are all sorts of deductions, and there are also anti-deductions, e.g. imputed rent for homeowners. The more common deductions are enumerated in separate fields, the others you can itemize on more free form input. It's not like all of those deductions are obvious here either. When we moved back to Switzerland, I had an accountant do my taxes once or twice, but after that, I knew what kinds of deductions I could claim. Switzerland has no AMT, which is one of the more painful parts of the US filing process in my experience.
