• Most tax rates and allowances were announced in advance at the Autumn Statement, and the significant new proposals were all predicted – there were no surprises
• These key points include measures that were announced previously but are about to come into force
• Measures which have been announced but will not take effect during 2024 are listed separately below

Personal tax

• The main personal tax-free allowance (£12,570) and the 40% tax rate threshold (£50,270) remain frozen at their present levels until the end of 2027/28, representing a tax rise where income increases
• The 45% threshold remains £125,140 for 2024/25
• Tax-free dividend allowance falls from £1,000 to £500, and CGT annual exempt amount falls from £6,000 to £3,000, for 2024/25
• ISA investment limit remains £20,000 – a new ‘British ISA’ to encourage investment in British companies, with a £5,000 annual limit, will be introduced after consultation
• Further reductions in National Insurance Contributions in addition to those announced in the Autumn Statement: from 6 April 2024, Employees’ Class 1 NIC reduced from 10% (was 12% up to 5 January 2024) to 8%, and Class 4 NIC rate for the self-employed cut from 9% to 6% (a cut to 8% was announced in the Autumn Statement)
• The income threshold above which Child Benefit is clawed back by the High Income Child Benefit Charge (HICBC) will rise from £50,000 to £60,000 in 2024/25, and the clawback will be spread over £20,000 of income (instead of £10,000 up to now)
• The higher rate of CGT payable on disposals of residential property will fall from 28% to 24% for disposals from 6 April 2024
• Stamp Duty Land Tax Multiple Dwellings Relief to be abolished from 1 June 2024
• IHT thresholds and rates unchanged to the end of 2027/28

Other measures
