It's not just the complexity. In Australia, we have a ridiculously complicated tax system but the free application that the Australian Taxation Office (ATO) provides walks you through it pretty easily. Usually it only takes me about an hour to file it online, and then you have a return deposited to your bank account (or you get an invoice if you're unlucky) in eight to fifteen days. The UI is pretty crap but on the whole the app works pretty well. It can 'pre-fill' quite a lot - stuff like salary that has been pre-taxed (called the PAYG system here), share dividends and franking information, bank interest details. I wish company tax returns were similarly simple, but those have to go in either on paper or electronically through an accountant.
