UK Capital Gains Tax Statutory Rules

1. What is the current Annual Exempt Allowance for CGT?

For the 2024/2025 tax year onwards, the Annual Exempt Allowance is set at £3,000 per individual (and £1,500 for personal trusts). This represents a major reduction from £12,300 in 2022/23 and £6,000 in 2023/24. Married couples and civil partners each have their own separate £3,000 allowance, meaning a couple can realize up to £6,000 in capital gains completely tax-free by jointly owning assets.

2. What are the CGT rates for Residential Property vs. Shares?

Capital gains tax rates vary substantially depending on the asset class and your total income:

  • Residential Property (not covered by PRR): 18.0% for basic rate taxpayers and 24.0% for higher and additional rate taxpayers (reduced from 28% on 6 April 2024).
  • Other Chargeable Assets (Shares, Crypto, Collectibles): 10.0% for basic rate taxpayers and 20.0% for higher and additional rate taxpayers.
  • Business Asset Disposal Relief (BADR): Flat rate of 10.0% on qualifying business sales up to a lifetime cap of £1,000,000.

3. What is the 60-Day Reporting Rule for UK Residential Property?

If you make a capital gain on the disposal of UK residential property that results in a tax liability (such as a second home or rental buy-to-let), you must report the gain and pay the estimated CGT to HMRC within 60 days of the completion date using HMRC’s online Capital Gains Tax on UK property account.
