Property CGT — common questions

What are the CGT rates on property?
From 2024/25 residential property gains are taxed at 18% within your remaining basic-rate band and 24% above it, after the £3,000 annual exempt amount. Your other income decides how much of the gain falls in each band.
What can I deduct from the gain?
You can deduct the purchase price, buying and selling costs (SDLT, legal and agent fees) and the cost of capital improvements — but not mortgage interest or routine repairs. This calculator covers the common deductions; check reliefs like Private Residence Relief with an accountant.
