Capital Gains Tax on residential property was reduced to 18% (basic-rate slice) and 24% (higher/additional-rate slice) from April 2024 — but the 60-day reporting deadline still catches landlords who think they've got until the next Self Assessment return.
Enter your purchase price, sale price, allowable costs (legal fees, improvement works that qualify, selling costs), and your marginal tax band. The calculator works out your taxable gain, applies the annual CGT allowance, and shows the tax due broken into basic and higher-rate portions.
Flags the 60-day reporting deadline and the separate CGT Property Return you'll need to file. Separate from your Self Assessment. Penalties for missing the 60-day window are material.
