Sounds technical? It’s actually a quiet win for some taxpayers. If you bought property before July 2024 and are planning to sell, this update could lower your capital gains tax bill. Because CII adjusts your original purchase price for inflation, a higher index means your ‘indexed cost’ goes up; which shrinks your taxable profit. But here’s the catch: this benefit is now mostly dead for new sales after July 2024. Only if you’re selling pre-2024 land or buildings can you still choose between 20% tax with indexation or 12.5% without it. So while this tweak doesn’t affect most new sellers, if you’re in that grandfathered group, it’s still worth running the numbers. A small change; but for the right person, it might mean keeping more of your money.
