here in NZ most people don't even have to file taxes - we have NO exemptions, if you have one job your boss will have gotten your tax right, your bank will withhold tax on interest at your declared marginal rate - if you have multiple jobs filing a one page web form might get you a refund (with interest!).

Same here, but I have to actually confirm that I have seen it and sign it (via text message, online or paper). The stuff I have to manually add to the filing is s.g if I bought or sold a house or did any complicated stock market trades (but then the broker or bank usually lets you take that form pre filled from them at least).
