The Chancellor, Kwasi Kwarteng, has presented his mini-budget and 'The Growth Plan 2022' announcing major reversals to a large chunk of his predecessor's tax policies. Together with a package of tax cuts, these would have greatly benefit owner-managed businesses but almost all were reversed on 17 October 2022.

National Insurance Contributions (NICs)

From 6 November 2022 (or as soon as payroll systems can be changed, if later):

  • The 1.25% increase in NICs rates which has applied since 6 April 2022 is reversed.  
  • Employee rates will return to 12% and 2%, with an employer's rate of 13.8%.
  • The self-employed rate will return to 9% and 2%.
  • The Health and Social Care Levy, due to be implemented in April 2023, is abolished.

    • Rates revert to 7.5% and 32.5% from April 2023.

Income Tax

From 6 April 2023

    • This measure has been brought forward from April 2024. [This proposal was reversed on 17 October 2022]

  • Similarly, the abolition of the additional rate of Income Tax in Scotland applies only to savings and dividend income as these tax rates have not been devolved.

Stamp Duty Land Tax (SDLT)

From midnight on 23 September 2022: 

  • The Residential nil-rate threshold increases from £125,000 to £250,000.

This measure does not apply to Scotland or Wales which operate their own land transactions taxes.

A new digital, VAT-free shopping scheme will be created to attract non-resident visitors.

  • Non-UK visitors to Great Britain will be able to obtain a VAT refund on goods bought in the high street, airports and other departure points and exported from the UK in their personal baggage.

Corporation Tax

  • The planned increase in Corporation Tax from 19% to 25% in April 2023 will be reversed.
  • The 19% rate will continue to apply.
  • Diverted Profits Tax was also due to increase from 25% to 31% in April 2023. This measure is also reversed, but Diverted Profits Tax will remain at 6% above the main rate of Corporation Tax at 25%. [This proposal was reversed by the Prime Minister on 14 October 2022]

  • The 2017 and 2021 reforms to Off-Payroll Working in the public and private sectors will be reversed.

  • Qualifying companies will be able to issue up to £60,000 of CSOP options to employees, double the current £30,000 limit.

See Changes to CSOP rules

  • Companies will be able to raise up to £250,000 of SEIS investment. The current limit is £150,000.

    • Stamp Duty Land Tax (SDLT), 100% business rates relief, enhanced capital allowances for plant and machinery and enhanced Structures and Buildings Allowance rate and a zero rate of Employers NICs for new employees.

See New Investment Zones

Office of Tax Simplification

  • The Treasury's independent tax simplification body is to go.
  • The government has now decided that the best way to simplify the tax system is to embed the concept of simplification into government rather than having a separate body to oversee the process.

See Office of Tax Simplification to go

Alcohol Duty

  • The government will freeze all duties for one year from 1 February 2023.
  • Following consultation, there will be a reform package for Alcohol Duty.[This measure was scrapped on 17 October 2022]
  • Small Brewers Relief will become Small Producer Relief and will be extended to small producers of wines, spirits, ciders and lower-strength beers. 


As previously announced, the government will provide two support packages for domestic and business users of electricity and gas.

Domestic users

  • Cost of living support package via an Energy Price Guarantee which supports households through a cap on the unit rate of electricity and gas. 
  • The newly announced support package will run alongside the existing measures already set out:
    • £400 per household paid in six instalments from this October under the Energy Bills Support Scheme.
    • £1,200 of extra support for the most vulnerable.

See Energy Price Guarantee 

Non-domestic and business users

  • The Energy Bills Support Scheme will provide support for businesses for a six-month period.
  • The scheme will be reviewed after three months.
  • There is the possibility of an extension of the scheme for certain businesses after six months.

See Energy Bill Relief Scheme for business


Banker's bonuses

  • The EU's cap on bankers' bonuses is to be lifted in the UK.
  • The rationale is that it was ineffective as employees received higher base salaries in compensation.

Deregulation of pensions

  • Draft regulations to reform the pensions regulatory charge cap will be brought forward, according to the Growth Plan.
  • This will give defined contribution pension schemes flexibility to invest in the UK’s most innovative businesses and productive assets creating opportunities to deliver higher returns for savers 

Funding for government

According to the Chancellor's Growth Plan:


  • The Monetary Policy Committee of the Bank of England is responsible for controlling inflation and has taken action by raising interest rates to 2.25%.
  • It will begin active sales of UK government bonds to reduce the stock of purchased bonds by £80 billion over the next twelve months.


  • The Debt Management Office Net Financing Requirement (NFR) in 2022-23 has been revised upwards, from £161.7 billion in April 2022 to £234.1 billion in September 2022.
  • This will be financed by additional gilt sales of £62.4 billion and net Treasury bill sales for debt management purposes of £10.0 billion, relative to April.
