Corporation tax rates

- Profits up to £50,000 incur corporation tax at 19%.
- Profits over £250,000 incur corporation tax at 25%.
- Marginal relief applies to profits between £50,000 and £250,000.
- Businesses with profits that can be attributed to patented inventions and certain other intellectual property can elect to pay a reduced rate of 10% tax on those profits.
Findcorporation tax rates for earlier years by visiting the HMRC pages.
You can use the HMRC marginal relief calculator for company profits between the small profits rate threshold and the main corporation tax threshold.
From 1 April 2023 until 31 March 2026, businesses investing in qualifying plant and machinery will qualify for a 100% first-year allowance for main rate assets meaning they can write off the full cost in the year of investment.
Companies investing in special rate (including long life) assets will benefit from a 50% first-year allowance in the year in which they make the investment.
The Structures and Building Allowance is 3% for both corporation and income tax purposes.
The annual investment allowance (AIA) has been fixed at £1 million.
For investments in plant and machinery over the AIA, writing down allowances spread the tax deductions over time. The rates are:
- 18% - main writing down allowance;
- 6% - special rate pool;
- 3% - structures and building allowance from 1 April 2020 for corporation tax and from 6 April 2020 for income tax;
For motor cars:
- 100% on electric cars and those with low emissions, less than 50g/km;
- 18% for those with emissions between 50 and 110g/km;
- 6% for those with emissions over 110g/km.
Special rules apply for some types of assets. Guidance can be found on the GOV.UK pages.
Chargeable gains and indexation allowances
For companies, gains or losses on disposals of assets are dealt with through corporation tax.
If you sell or dispose of a business asset, corporation tax is payable on any profit (chargeable gain). When working out your gain, you can use indexation allowance to reflect the increase in value from when the asset is acquired to when it is eventually disposed of.
For sole traders and partnerships, disposals of assets are dealt with through capital gains tax, usually as part of their annual self assessment return.
Business rates and stamp duty
Find current and historic business rate multipliers by visiting the Valuation Office Agency website.
Stamp duty on non-residential property purchases and lease premiums has remained the same since 17 March 2016:
- property value up to £150,000 at 0%;
- property value between £150,001 and £250,000 at 2%;
- property value over £250,000 at 5%.
There is an additional 2% surcharge for non-UK residents purchasing residential property in England and Northern Ireland from 1 April 2021.
