I find the Dutch way (slightly) crazy, as someone from NZ for the most part, you just don't file taxes and it works out. If you have a more complicated situation you might need to, but otherwise there's no point. Everything is withheld correctly.
At least the Dutch ones tend to just be click-click-check-done, so it's not too bad. But it was sad moving to filing annual tax returns from a much simpler system.
