UK Capital Gains Tax 2025: Allowances, Property Sales, and Crypto

UK Capital Gains Tax (CGT) 2025

The UK’s 2025 capital gains regime features lower annual exemptions and tighter reporting. Whether selling property, shares, or crypto, planning ahead preserves wealth and avoids penalties.

Annual Exemption and Rates

The annual exempt amount falls to £3,000 (£1,500 for trusts). Gains above the allowance are taxed at 10%/20% for basic/higher rate taxpayers (18%/24% for residential property). Track cumulative gains to avoid unexpected tax bills.

Residential Property Reporting

Report UK residential property disposals within 60 days via the CGT on UK Property service and pay estimated tax. Self-assessment still required for the overall year—reconcile figures when filing.

Investment and Crypto Assets

Use the share matching rules (same-day, 30-day “bed and breakfast,” and Section 104 pools) to compute gains accurately. Crypto assets follow similar principles; keep transaction logs from exchanges or wallets to substantiate calculations.

Reliefs and Losses

Offset current-year and carried-forward capital losses to reduce taxable gains. Entrepreneurs’ Relief (Business Asset Disposal Relief) offers a 10% rate on qualifying business disposals up to £1 million.

Tip: Schedule disposals across tax years, transfer assets to spouses to utilise their allowances, and maintain meticulous records for HMRC enquiries.
