Key facts

  • CGT was charged at a flat 18% from 2008/09 to 2009/10, replacing the previous taper relief system.
  • The 18%/28% split was introduced in June 2010, creating separate rates for basic and higher-rate taxpayers.
  • From 2016/17, non-property assets were taxed at 10%/20% while residential property remained at 18%/28%.
  • The October 2024 Budget unified rates to 18%/24% for all asset types from 30 October 2024.
  • The Annual Exempt Amount has fallen from £10,100 in 2008/09 to just £3,000 in 2025/26.

Before 2008: Taper Relief Era

Before 6 April 2008, capital gains were taxed at Income Tax rates (10%, 20%, and 40%) but with two significant reliefs that reduced the effective rate:[2]

  • Indexation allowance: Adjusted the base cost of an asset for inflation (using the Retail Prices Index) from the date of acquisition to April 1998
  • Taper relief: Reduced the chargeable gain based on the length of ownership from April 1998 onwards. Business assets received more generous taper than non-business assets

For business assets held for 2 or more years, taper relief reduced the gain by 75%, giving an effective CGT rate of just 10% for higher-rate taxpayers (40% × 25% = 10%). Non-business assets required 10 years to reach maximum taper of 40%.

2008/09 – 2009/10: The Flat 18% Rate

The 2008 Budget swept away taper relief and indexation allowance for individuals, replacing them with a single flat rate of 18% on all capital gains. This was a major simplification but created controversy:[2]

  • Business owners saw their effective rate increase from 10% to 18%
  • Entrepreneurs’ Relief was introduced in 2008 to partially compensate, offering a 10% rate on the first £1 million of qualifying business gains (initially the lifetime limit was lower)
  • The indexation allowance was abolished for individuals (but retained for companies)

2010/11 – 2015/16: The 18%/28% Split

From 23 June 2010 (part-way through 2010/11), the coalition government introduced a split rate:[2]

BandRate
Basic-rate taxpayers18%
Higher and additional-rate taxpayers28%
Entrepreneurs’ Relief10%

These rates applied to all asset types (shares, property, and other assets) equally. The 28% rate was significantly higher than the pre-2008 effective rates for many taxpayers.

2016/17 – 2023/24: The Four-Rate System

From 6 April 2016, rates were cut for non-property assets while residential property retained the higher rates:[2]

BandShares & Other AssetsResidential PropertyEntrepreneurs’ / BADR
Basic rate10%18%10%
Higher / additional rate20%28%10%

This four-rate system lasted from 2016/17 through to part-way through 2024/25. The residential property surcharge of 8 percentage points above the non-property rates reflected the government’s policy of taxing property gains more heavily.

6 April 2024 change: From 6 April 2024 (within the 2024/25 tax year), the higher rate on residential property was reduced from 28% to 24%, while other rates remained unchanged. This was a mid-year change that created a brief period of different property rates within the same tax year.[3]

The October 2024 Budget: Unified Rates

The Autumn Budget on 30 October 2024 unified CGT rates across all asset types for disposals on or after that date:[3]

BandAll Assets (from 30 Oct 2024)BADR (2024/25)
Basic rate18%10%
Higher / additional rate24%10%
Trustees24%10%

The key changes were:

  • Non-property basic rate: 10% → 18% (an 8 percentage point increase)
  • Non-property higher rate: 20% → 24% (a 4 percentage point increase)
  • Residential property higher rate remained at 24% (unchanged from 6 April 2024)
  • Residential property basic rate remained at 18%

BADR Rate Changes: 2024 – 2026

The October 2024 Budget also announced a phased increase to the Business Asset Disposal Relief rate:[4]

PeriodBADR RateLifetime Limit
Before 6 April 202510%£1 million
6 April 2025 – 5 April 202614%£1 million
From 6 April 202618%£1 million

Investors’ Relief follows the same rate increases as BADR.

A dramatic reduction: The AEA has been cut by over 75% in just three years — from £12,300 in 2022/23 to £3,000 in 2024/25 and 2025/26. This means far more people will have taxable gains, even on relatively modest disposals. Combined with higher rates, the effective CGT burden has increased significantly for many taxpayers.[2]

Frequently Asked Questions

What were CGT rates before 2008?

Before 6 April 2008, capital gains were added to income and taxed at income tax rates (up to 40%). However, taper relief reduced the chargeable gain based on how long you held the asset. Business assets could receive up to 75% taper relief after 2 years, giving an effective rate as low as 10%.

When did CGT rates change to 18% and 24%?

The rates changed on 30 October 2024 as part of the Autumn Budget. The lower rate on non-property assets was increased from 10% to 18%, and the higher rate was increased from 20% to 24%. Residential property rates changed from 18%/28% to 18%/24%.

How has the Annual Exempt Amount changed over time?

The AEA rose from £9,600 in 2008/09 to a peak of £12,300 in 2020/21 to 2022/23. It was then cut to £6,000 in 2023/24, £3,000 in 2024/25, and remains at £3,000 for 2025/26. This represents a 75% reduction from the peak.

What is the BADR rate for 2025/26?

Business Asset Disposal Relief is charged at 14% for 2025/26 (increased from 10% on 6 April 2025). It is scheduled to increase further to 18% from 6 April 2026. The lifetime limit remains £1 million.
