How this is worked out

Capital Gains Tax uses your other taxable income to decide which band your gain falls into. The annual exempt amount is £3,000 (dropped from £6,000 in 2023/24 and £12,300 before that).

Rates as of 30 October 2024: 18% in the basic band, 24% above — same for shares, crypto, and second residential property. Pre-Oct 2024 the non-property rates were 10/20%.

Gains inside an ISA or SIPP are not taxable. Selling your only home is normally covered by Private Residence Relief.
