Capital Gains Tax UK 2025/26: Rates, Allowances and How to Pay Less
The 2025/26 tax year ends on 5 April 2026 — today. If you hold investments, property, or business assets outside a tax wrapper, your Capital Gains Tax position matters more than it has in a decade. Three changes hit at once this year. The annual exempt amount stays frozen at £3,000 — down 75% from £12,300 just three years ago. The Autumn Budget 2024 raised CGT on shares and other non-property assets from 10%/20% to 18%/24% for all asset types, effective from 6 April 2025. And Business Asset Disposal Relief jumped from 10% to 14%. The net effect: a higher-rate taxpayer selling £50,000 of shares now pays £11,280 in CGT, up from £9,400 under the old rates — a 20% increase in the tax bill on the same gain. This guide covers every rate, relief, and deadline for 2025/26, plus the strategies that actually reduce your liability. If you have unrealised gains, today is your last chance to act before the new tax year resets your allowance.
