Corporation  tax rates
It had been previously announced that the expected increase in the  rate of corporation tax for many companies from April 2023 to 25% would not go  ahead. However the government announced on 14 October 2022 that this increase  will now proceed and this has been confirmed.
This means that, from April 2023, the rate will increase to 25% for  companies with profits over £250,000. The 19% rate will become a small profits  rate payable by companies with profits of £50,000 or less. Companies with  profits between £50,001 and £250,000 will pay tax at the main rate reduced by a  marginal relief, providing a gradual increase in the effective corporation tax  rate.
In addition:
    - bank  corporation tax surcharge changes will proceed, meaning that from April 2023  banks will be charged an additional 3% rate on their profits above £100 million  and
 
    - from April  2023 the rate of diverted profits tax will increase from 25% to 31%.
 
Capital  allowances
The Annual Investment Allowance (AIA) gives a 100% write-off on  certain types of plant and machinery up to certain financial limits per  12-month period. The limit has been £1 million for some time but was scheduled  to reduce to £200,000 from April 2023. The government has announced that the  temporary £1 million level of the AIA will become permanent and the proposed  reduction will not occur.
Up to 31 March 2023, companies investing in qualifying new plant and  machinery are able to benefit from capital allowances, generally referred to as  'super-deductions'. These reliefs are not available for unincorporated  businesses.
Comment
Companies incurring expenditure on plant and machinery should    carefully consider the timing of their acquisitions to optimise their cashflow.
The government will also extend the 100% first year allowance for  electric vehicle chargepoints to 31 March 2025 for corporation tax  purposes and 5 April 2025 for income tax purposes.
Research and Development
For expenditure on or after 1 April 2023, the Research and  Development Expenditure Credit (RDEC) rate will increase from 13% to 20% but  the small and medium-sized enterprises (SME) additional deduction will decrease  from 130% to 86% and the SME credit rate will decrease from 14.5% to 10%.
Comment
This government states that 'this reform ensures that taxpayer    support is as effective as possible, improves the competitiveness of the RDEC    scheme, and is a step towards a simplified, single RDEC-like scheme for all'.    The government will consult on the design of a single scheme and consider    whether further support is necessary for R&D intensive SMEs. As    previously announced at Autumn Budget 2021, the R&D tax reliefs will be    reformed by expanding qualifying expenditure to include data and cloud costs,    refocusing support towards innovation in the UK, and targeting abuse and    improving compliance.
Seed Enterprise Investment Scheme
From April 2023, companies will be able to raise up to £250,000 of  Seed Enterprise Investment Scheme (SEIS) investment, a two-thirds increase. To  enable more companies to use SEIS, the gross asset limit will be increased to  £350,000 and the age limit from two to three years. To support these increases,  the annual investor limit will be doubled to £200,000.
Company Share Option Plan
From April 2023, qualifying companies will be able to issue up to  £60,000 of Company Share Option Plan (CSOP) options to employees, twice the  current £30,000 limit. The 'worth having' restriction on share classes within  CSOP will be eased, better aligning the scheme rules with the rules in the  Enterprise Management Incentive scheme and widening access to CSOP for growth  companies.
VAT
The VAT registration and  deregistration thresholds will not change for a further period of two years  from 1 April 2024, staying at £85,000 and £83,000 respectively.
Comment
According to the government, at    £85,000, the UK's VAT registration threshold is more than twice as high as    the EU and OECD averages.
Vehicles
The government will set the  rates for the taxation of company car benefits until April 2028 to provide long  term certainty for taxpayers and industry. Rates will continue to incentivise  the take up of electric vehicles.
In addition, from 6 April 2023  car and van fuel benefits and the van benefit charge will increase in line with  inflation.
Comment
In addition, from April 2025    electric cars, vans and motorcycles will begin to pay Vehicle Excise Duty in    the same way as petrol and diesel vehicles. According to the government, this    will ensure that all road users begin to pay a fair tax contribution as the    take up of electric vehicles continues to accelerate.
