Hello everyone, In 2023, I started a very small secondary occupation, which ended the year at a loss (partly due to a large amount of stock + investments). I have now filled in part 2 of my personal income tax for the first time and, to my great surprise, I will be claiming back approximately 1,300 euros for part 2. I have not paid any withholding tax and am not entitled to any tax relief (no children, loans, pension savings, etc.) through my secondary occupation. Can anyone explain why I will still be receiving a refund?
