The new Chancellor of the Exchequer, Kwasi Kwarteng, delivered a fiscal statement referred to as The Growth Plan 2022 on 23 September 2022. The statement to a packed House of Commons centred on the government’s plans for generating growth.

Colloquially referred to as a mini-budget, it would perhaps be more fitting to refer to the statement as a maxi-budget. In his first major statement since becoming Chancellor, a number of striking measures were announced representing a major shift in policy direction for the Exchequer.

Paying an estimated £45 billion for these measures will see borrowing levels soar as the government attempts to grow the economy and avoid a deep recession. It is hoped that these measures will help to reduce peak inflation by around 5%.

The Chancellor was also keen to remind the House of the measures already announced to tackle spiralling energy costs. This included the Energy Price Guarantee which will see the average household have their energy bills capped at £2,500 a year for the next two years, a £400 energy rebate for UK households as well as more support for vulnerable households.

A new Energy Bill Relief Scheme to help cut energy bills in the non-domestic sector will also apply to energy usage from 1 October 2022 to 31 March 2023 and will automatically be applied to qualifying businesses fuel costs.

Taxation changes

National Insurance

Before the Chancellor rose to his feet, a number of other important announcements had already been made. The first of these related to the new Prime Minister’s pledge to reverse the 1.25% rise in National Insurance contributions (NICs) that came into effect at the start of the 2022-23 tax year on 6 April 2022. This will see the reversal of the increase from 6 November 2022 and will cover Class 1 (both employee and employer), Class 1A , Class 1B and Class 4 (self-employed) NICs.

It was also confirmed by the Chancellor that the ring-fenced Health and Social Care Levy of 1.25% due to be introduced from April 2023 will not go ahead as originally planned. These measures will provide average savings of around £135 in this tax year and £330 in 2023-24 for almost 28 million people across the UK as well as a tax cut for 1 million businesses. The 1.25% increase to the rate of Income Tax on dividends which took effect in April 2022 will remain in place until April 2023.

Income Tax

The Chancellor announced that the government will reduce the basic rate of Income Tax to 19% (from 20%) with effect from April 2023. This brings forward the planned 1p cut in the basic rate by 12 months. According to HM Treasury, the 19% rate is the lowest the basic rate has ever been in the modern Income Tax system. There will also be a four-year transition period for Gift Aid relief to maintain the Income Tax basic rate relief at 20% until April 2027 to help support almost 70,000 charities.

In a surprise move, the Chancellor also announced that the Additional Rate of Income Tax of 45% that applies to taxpayers with an annual income over £150,000 will be scrapped. The 45% rate has been in place since April 2013 and its removal from next April will mean that there will be a single higher rate of Income Tax of 40%.

The reductions will not apply to the non-savings and non-dividend income of Scottish taxpayers because the power to set these rates is devolved to the Scottish Government. However, the Scottish government will receive additional funding which they can use as they see fit, including a reduction on Income Tax or other taxes, or increased spending. The Income Tax rate cuts will apply to Welsh taxpayers.

Income Tax and dividend income

The tax rates payable on dividend income will revert back to those that applied before April 2022, from April 2023 in line with the 1.25% decrease in NIC contributions.

The rates that will apply in all regions of the UK from 6 April 2023 are:

  • Dividends that form part of the basic rate band – 7.5% (8.75% 2022-23)
  • Dividends that form part of the higher rate band – 32.5% (33.75% 2022-23)

Dividends that form part of the additional rate band and are currently liable to tax at 39.35% will be withdrawn from 6 April 2023 to align with the removal of the 45% additional Rate of Income Tax. This change applies UK-wide.

The dividend tax is charged on taxable dividend income an individual receives that falls outside of the personal allowance and that exceeds the dividend allowance. The current £2,000 dividend tax-free allowance is unchanged.

Those who would have otherwise been additional rate taxpayers will from April 2023 benefit from a Personal Savings Allowance of £500, in line with higher rate taxpayers. This was not previously available to them.

Stamp Duty Land Tax (SDLT)

The Chancellor announced a permanent increase of the SDLT nil rate band to £250,000 (from £125,000) with immediate effect from the date of his announcement, 23 September 2022.

Prior to the announcement, no SDLT was payable for first-time buyers making a purchase of up to £300,000. This limit has now been increased by £125,000 with immediate effect to £425,000. The first-time buyers relief also increases the nil-rate threshold to £425,000 (£300,000 prior to 23 September 2022) for first-time buyers of properties costing up to £625,000 (£500,000 prior to 23 September 2022). There is no relief available for first-time buyers spending more than £625,000 on a property. There are a number of requirements that must be met in order to qualify for the relief.

These measures will reduce stamp duty bills across the board for all movers by up to £2,500 with first-time buyers able to access up £11,250 in relief.

It is important to note that these measures apply to England and Northern Ireland only. Any changes to the Land and Buildings Transaction Tax in Scotland or the Land Transaction Tax in Wales will be announced separately


Reversal of Corporation Tax increase

The Corporation Tax main rate had been set to increase from 19% to 25% from 1 April 2023 for companies with profits over £250,000. A Small Profits Rate (SPR) of 19% was also to have been introduced from the same date for companies with profits of up to £50,000 with a marginal rate of Corporation Tax. This would apply to companies making profits of between £50,000 and £250,000 meaning an incremental rise in the Corporation Tax rate from 19% to 25% depending on how much profit a firm was making.

The Chancellor has now confirmed that these planned rises have been cancelled in full. This means that the Corporation Tax rate will remain at 19% for all firms, regardless of the amount of profits made. The Chancellor was excited to inform the House that this means the UK will have the lowest Corporation Tax rate in the G20 group of the world's major economies.

Annual Investment Allowance threshold

The Annual Investment Allowance (AIA) was permanently set at £200,000 for all qualifying expenditure on or after 1 January 2016. Following the pandemic, this limit had been temporarily increased (with a number of extensions) to £1 million.

This increased threshold was set to expire on 31 March 2023, but the Chancellor announced that the limit will be permanently extended to £1 million. This will give business owners thinking about high-value investments in qualifying assets some comfort and remove the need to rush any capital acquisitions.

Investment Schemes

The Seed Enterprise Investment Scheme (SEIS) is to be extended to help more UK start-ups raise higher levels of finance.

The Enterprise Investment Scheme (EIS) and Venture Capital Trusts (VCT) will be extended beyond 2025.

Investment Zones

As part of the Growth Plan, the government is in discussions with 38 local authorities to establish investment zones in England.

The government will also work with the devolved administrations and local partners to deliver this opportunity to drive local growth in Scotland, Wales and Northern Ireland.

These Investment Zones will be designed to encourage investment and new economic activity, supporting growth and jobs. The Investment Zones will benefit from lower taxes and more relaxed planning frameworks to encourage rapid development and business investment.


The Chancellor announced that VAT-free shopping for overseas visitors is to be reintroduced to help encourage more tourists to the UK. The VAT Retail Export Scheme was cancelled on 1 January 2021. The old paper-based system will be replaced with a modern, digital one and will be put in place as soon as possible.


  • The planned increases next year in the duty rates for beer, cider, wine and spirits in line with RPI have all been cancelled.
  • The cap on bankers’ bonuses is to be scrapped to enhance London’s reputation as a worldwide banking centre.
  • The Office of Tax Simplification is to be wound down with responsibility for tax simplification being handed to Government.
  • There will be moves to simplify IR35 rules, including the repeal of the 2017 and 2021 reforms.
