The UK system is similar - a web-based form, starts off asking you some basic questions ("Did you give to charity?" "Are you a director of a company?" etc etc) then tailors it directly for your needs, with the "obvious" stuff being pre-filled from your usual employer-deducted taxes. The wording is clear and simple to understand (...most of the time - some of it is a bit "legalese" in places but it is getting better each year) Takes about 20 minutes to do it each year if you have all of your figures to hand... (if you are disorganised and have not been keeping track of any capital gains losses/gains etc throughout the year then it will take longer as you'll need to work those figures out first) My wife is dual-national US-UK, and she does her UK one herself without much fuss as well, but seems like she has to employ an accountant in the US to do her US return due to complexity and convolutedness.
