I don't know the US tax system but I find it alarming how many US citizens seem to end up in the legal system because of it. In the UK the tax office (HMRC) generally takes what's owed from an employed or pensioned individual before they get paid so it couldn't be simpler.
As a self-employed person I have to calculate and submit my own tax returns which is still easy for me because I have an accountant do it for me. Ironically what he saves me in paying taxes more than covers his fees so it's all good.
