HMRC’s new 2024-25 CGT ‘adjustment’ calculator

Capital Gains Tax (CGT) rates were announced at the 2024 Autumn Budget, from 30 October 2024 (during the 2024-25 tax year):

• The lower rate of CGT increased from 10% to 18%.
• The higher rate of CGT increased from 20% to 24%.
• The rate of CGT that applies to trustees and personal representatives increased from 20% to 24%.

The rates for residential property gains remain at 18% for basic rate taxpayers and 24% for higher rate taxpayers.

If you made disposals  before and after 30 October 2024 and if you use HMRC’s software, you will need an additional adjustment using separate CGT rates to get a correct CGT result.
