Capital Gains Tax on shares, crypto, property, or a business sale — current £3,000 allowance, the 18%/24% rate split driven by your income, and the BADR 14% → 18% ramp. Computes UK Capital Gains Tax on a disposal using the current rules: the £3,000 annual exempt amount, the 18%/24% rates that have applied to ALL assets since 30 October 2024, the income-stacking rule that decides how much of the gain falls at 18% vs 24%, and Business Asset Disposal Relief with its stepping rate (14% in 2025-26, 18% from 6 April 2026) and £1 million lifetime limit. General AI reliably gets this wrong three ways at once — quoting the abolished £12,300 allowance, the dead 10%/20% share rates, and a BADR rate from the wrong year — and answers without asking for your taxable income, the input that actually sets the rate.
