In Australia you do your taxes and then a few weeks later you either get a refund or a bill. If there's anything that doesn't add up in your filing they may ask you about it. Nothing to regret unless you knowingly filed incorrect information. Edit: a lot of it is pre-filled (payroll, bank interest, investment distributions in my case), you just need to check against your own records.
