Complete Guide to UK Capital Gains Tax (CGT)

1. The Autumn Budget 2024 CGT Overhaul

In the Autumn Budget on 30 October 2024, the UK Government raised the main CGT rates:

  • Basic Rate: Increased from 10% to 18% on shares, crypto, and other assets.
  • Higher Rate: Increased from 20% to 24% on shares, crypto, and other assets.
  • Residential Property: Maintained at 18% (basic) and 24% (higher).

2. Annual Tax-Free Allowance (£3,000)

Every individual in the UK is entitled to an Annual Exempt Amount (AEA) of £3,000. This allowance is "use it or lose it" and cannot be carried forward to future tax years. Spouses or civil partners can transfer assets prior to sale to utilize both allowances, achieving up to £6,000 tax-free.

3. Business Asset Disposal Relief (BADR)

Qualifying business directors and sole traders selling all or part of their business can benefit from BADR, keeping CGT at 10% up to a lifetime cap of £1,000,000. Under current legislation, BADR will increase to 14% from 6 April 2025 and 18% from 6 April 2026.

4. Allowable Deduction Rules

You can lawfully deduct:

  • Legal fees, Stamp Duty (SDLT), and survey fees paid when acquiring the asset.
  • Capital enhancement expenditure (e.g. building an extension or installing central heating; routine repairs and decorating do not qualify).
  • Incidental selling fees (estate agency commission, advertising, legal conveyancing).

Frequently Asked Questions (UK Capital Gains Tax)

Do I pay Capital Gains Tax when selling my own home? ▼

Usually no. Under Private Residence Relief (PRR), you do not pay any Capital Gains Tax when selling a property that has been your main and only residence throughout the period of ownership.

How is cryptocurrency taxed in the UK? ▼

HMRC treats Bitcoin, Ethereum, and other cryptoassets as capital assets. Selling crypto for fiat, swapping one token for another, or using crypto to buy goods triggers a taxable disposal subject to the 18% or 24% CGT rates.

How do I report CGT on shares or crypto? ▼

You report gains on shares or cryptoassets via your annual Self Assessment tax return or by using HMRC's real-time Capital Gains Tax service by 31 December following the end of the tax year.

Can I gift assets to my spouse to avoid CGT? ▼

Yes. Gifts and transfers between spouses or civil partners who live together are treated on a 'no gain, no loss' basis. When the receiving spouse subsequently sells the asset, they can use their own £3,000 allowance and basic rate tax band.
