Good to know

  • An updated return lets you report income you missed by paying tax, interest and an additional tax that rises the longer you wait.
  • The additional tax is a percentage of the aggregate of tax and interest payable on the updated return.
  • Updated returns can be filed within 48 months from the end of the relevant assessment year (extended from 24 months by the Finance Act, 2025).
  • If the time for filing a belated or revised return for that year has not yet passed, that is usually the better route.
  • The full list of conditions and exclusions is in the law; check your facts with us before filing.
