Capital Gains Tax · 2026/27 rates
UK Capital Gains Tax Calculator
Estimate the Capital Gains Tax due on the disposal of residential property, investments, business assets and other chargeable gains using current 2026/27 rates and allowances.
This calculator provides an estimate only — not financial or legal advice.
- Results are illustrative and based on 2026/27 CGT rates and the Annual Exempt Amount. Rates and allowances change each tax year.
- The calculator does not account for reliefs such as Business Asset Disposal Relief, Investors' Relief, Private Residence Relief, or lettings relief, which may significantly reduce your liability.
- CGT interacts with Income Tax and may affect your tax band. The interaction with other taxes, losses brought forward, and share pooling rules are not modelled here.
- Specialist advice from a qualified tax adviser or solicitor is essential before making any disposal decisions. This tool is not a substitute for professional guidance.
