Navigating UK Corporation Tax 2023-24: Rates, Reliefs & Calculation
For businesses operating in the United Kingdom, understanding Corporation Tax is not just a compliance requirement; it's a critical component of strategic financial planning. The landscape of UK Corporation Tax underwent significant changes from 1 April 2023, reintroducing a tiered system that demands precision and foresight.

Understanding UK Corporation Tax for 2023-24
Corporation Tax is a tax on the taxable profits of limited companies and some other organisations, including clubs, societies, associations, and housing associations. If your company is based in the UK, it pays Corporation Tax on all its taxable profits, wherever in the world they arise. If your company is based outside the UK but has a UK branch or office, it pays Corporation Tax on the profits arising from its UK activities.
The Return of Tiered Rates
The most significant change effective from 1 April 2023 is the reintroduction of a tiered Corporation Tax system, replacing the flat 19% rate that applied to all profits since April 2017. This shift means that the amount of tax your company pays will now depend directly on its level of taxable profits. This move by HMRC aims to support smaller businesses while ensuring larger, more profitable companies contribute a higher percentage of their earnings.
This change necessitates a thorough understanding of your company's projected profits, as even small fluctuations can shift your business into a different tax bracket or alter your marginal relief calculation. For finance professionals, business owners, and accountants, staying abreast of these nuances is paramount to accurate financial reporting and effective tax planning.
The New Corporation Tax Rates Explained (2023-24)
The 2023-24 financial year introduces three distinct bands for Corporation Tax, each with its own implications for businesses.
1. The Small Profits Rate (19%)
Companies with taxable profits of up to £50,000 now qualify for the Small Profits Rate of 19%. This rate is a welcome relief for many small and medium-sized enterprises (SMEs), allowing them to retain more of their earnings for investment and growth. It reflects the government's commitment to fostering a supportive environment for smaller businesses.
It's crucial to note that this threshold is divided by the number of 'associated companies' a business has. If your company is part of a group or has associated companies, the £50,000 limit is proportionately reduced, which can significantly impact your tax liability.
2. The Main Rate (25%)
For companies with taxable profits exceeding £250,000, the Main Rate of Corporation Tax applies at 25%. This rate represents a substantial increase from the previous flat rate of 19% and underscores the importance of strategic tax planning for larger entities. Like the small profits rate, this £250,000 upper limit is also divided by the number of associated companies.
3. Marginal Relief: The Intermediate Zone
The most complex aspect of the new system is the Marginal Relief that applies to companies with taxable profits between £50,000 and £250,000. This relief aims to provide a smooth transition between the Small Profits Rate and the Main Rate, preventing a sudden jump in tax liability. Instead of a fixed rate, companies in this band pay tax at an effective rate that gradually increases from 19% to 25%.
The calculation for marginal relief can be intricate. The basic principle is that tax is calculated at the main rate of 25%, and then marginal relief is deducted. The relief is calculated using a specific fraction and depends on how far your profits are from the upper limit of £250,000. The effect is that for every pound of profit earned within this band, the effective tax rate is higher than 19% but lower than 25%. This complexity is precisely why a reliable calculator becomes an indispensable tool.
Practical Examples of Corporation Tax Calculation (2023-24)
Let's walk through some real-world examples to demonstrate how these rates and marginal relief are applied. For simplicity, these examples assume no associated companies.
Example 1: A Small Company (Below the Lower Limit)
Company A has taxable profits of £40,000 for the accounting period ending 31 March 2024.
- Applicable Rate: Small Profits Rate (19%)
- Calculation: £40,000 * 19% = £7,600
- Corporation Tax Payable: £7,600
In this scenario, Company A benefits directly from the lower small profits rate, keeping its tax burden manageable.
Example 2: A Large Company (Above the Upper Limit)
Company B has taxable profits of £350,000 for the accounting period ending 31 March 2024.
- Applicable Rate: Main Rate (25%)
- Calculation: £350,000 * 25% = £87,500
- Corporation Tax Payable: £87,500
Company B, with profits well above the upper threshold, pays tax at the full 25% main rate.
Example 3: A Company in the Marginal Relief Zone
Company C has taxable profits of £150,000 for the accounting period ending 31 March 2024. This company falls squarely within the marginal relief band (£50,000 to £250,000).
To calculate the tax payable, we use the following formula, which accounts for the marginal relief:
-
Calculate tax at the main rate: £150,000 * 25% = £37,500
-
Calculate Marginal Relief: The marginal relief fraction is 9/400. The relief is calculated on the portion of profits below the upper limit of £250,000. Marginal Relief = (£250,000 - Taxable Profits) * (9/400) Marginal Relief = (£250,000 - £150,000) * (9/400) Marginal Relief = £100,000 * (9/400) = £100,000 * 0.0225 = £2,250
-
Calculate Corporation Tax Payable: Corporation Tax Payable = Tax at Main Rate - Marginal Relief Corporation Tax Payable = £37,500 - £2,250 = £35,250
In this case, Company C's effective tax rate is (£35,250 / £150,000) * 100% = 23.5%. This demonstrates how marginal relief provides a gradual increase in the effective tax rate for profits within the intermediate band.
These examples highlight the critical need for accurate calculations, particularly within the marginal relief zone, where manual errors can lead to significant discrepancies. The complexity only amplifies when considering associated companies, which necessitate a division of the profit thresholds.
Optimising Your Corporation Tax Position
Beyond accurate calculation, proactive tax planning can significantly influence your company's Corporation Tax liability. Here are a few key areas to consider:
- Capital Allowances: Utilise capital allowances, such as the Annual Investment Allowance (AIA) or the full expensing regime, to deduct the cost of qualifying plant and machinery from your profits before tax.
- Research & Development (R&D) Tax Credits: If your company is involved in innovative projects, R&D tax credits can provide substantial relief, either through a reduced tax bill or a cash payment.
- Loss Relief: Understand how to utilise trading losses, either by carrying them back to previous periods or carrying them forward to offset future profits.
- Group Relief: For companies within a group structure, group relief allows one company to surrender its losses to another company within the same group, reducing the overall tax liability of the group.
- Profit Extraction Strategies: For owner-managed businesses, careful planning of salary, dividends, and pension contributions can optimise the overall tax burden for both the company and the individual.
Engaging with a qualified tax advisor is always recommended to explore these and other strategies tailored to your specific business circumstances. However, having an initial understanding and the ability to model different scenarios with a reliable calculator is an invaluable first step.

Frequently Asked Questions (FAQs)
Q: What is the UK Corporation Tax rate for small companies from April 2023?
A: From 1 April 2023, companies with taxable profits of up to £50,000 pay Corporation Tax at the Small Profits Rate of 19%.
Q: When do the new Corporation Tax rates apply?
A: The new tiered Corporation Tax rates, including the small profits rate, main rate, and marginal relief, apply to accounting periods starting on or after 1 April 2023. If your accounting period straddles this date, your profits will be apportioned, and different rates will apply to each part of the period.
Q: How does marginal relief work for Corporation Tax?
A: Marginal relief applies to companies with taxable profits between £50,000 and £250,000. It ensures a smooth transition between the 19% small profits rate and the 25% main rate. Essentially, tax is calculated at the 25% main rate, and then a specific amount of marginal relief is deducted, resulting in an effective tax rate that gradually increases from 19% to 25% as profits rise within this band.
Q: Do associated companies affect Corporation Tax thresholds?
A: Yes, absolutely. If your company has one or more 'associated companies' (generally, companies under common control), the profit thresholds of £50,000 (for the small profits rate) and £250,000 (for the main rate) are divided by the total number of associated companies plus your company. For example, if you have one associated company, these thresholds would be halved to £25,000 and £125,000 respectively.
Q: What is the deadline for paying Corporation Tax?
A: The general deadline for paying Corporation Tax is 9 months and 1 day after the end of your company's accounting period. However, 'large companies' (those with taxable profits over £1.5 million, or smaller thresholds if associated companies exist) must pay their Corporation Tax in instalments before this final deadline.
