If you've received a lump sum from a court order that includes the original property cost and accrued interest, you need to consider how to declare this for income tax. The key questions are whether the entire amount is a revenue or capital receipt, and if only the interest portion should be taxed. It's generally advised to consult a chartered accountant to determine the correct tax treatment, as the interest might need to be allocated across the years it relates to, potentially reducing your tax burden.
