Disclaimer: Figures use a single non-residential disposal with the published 2026/27 CGT rates and Annual Exempt Amount. Whether the higher- or basic-rate CGT band applies depends on your taxable income for the year. Residential property gains are taxed at higher rates; main-home disposals generally qualify for Private Residence Relief. Brought-forward losses and reliefs (e.g. BADR) can materially change the bill.
