Corporation tax rates UK had been following a single flat rate system for all businesses regardless of size up until April 2023. There are now two thresholds for the UK corporation tax: small profits and main rate.  

Understanding corporate tax liability is crucial for every business, no matter how much it earns. Learn more about the current rates, how marginal relief works, sectors under special tax regimes, how to pay tax online, and more in this article. 

What Are Corporation Tax Rates UK 2024/25? 

The corporation tax rates UK history show a trend of decrease. It was at a flat rate of 28% in 2010 until it decreased to 19% in 2015. This flat rate remained up until 2023 at which it rose to 25%.  

Corporation tax rates and reliefs depend on the business’ total taxable profits in an accounting period. Here are the corporation tax rates in UK for the current tax year and onwards: 

Tax Bracket Taxable Income Rates
Small Profits Rate
Less than £50,000
Main Rate
More than £250,000
Marginal Relief Fraction
Between £50,000 and £250,000

Marginal relief reduces a company’s tax liability if its profits fall within the upper and lower limit (discussed further below). Take note that the above rates only apply to non-ring fence (oil and gas) companies. Special tax treatments apply to other sectors as part of anti-avoidance tax measures. 

Non-resident taxpayers with a permanent establishment in the UK are subject to the same corporation tax rate system, as well as clubs, co-operatives, or unincorporated organisations. Foreign owners of UK establishments may want to check our double taxation guide. 

They can also use our Corporation Tax Calculator UK to get a rough estimate of business tax liability, whether they are a UK-resident business or not. To arrive at the most accurate calculation, our tax experts consider all aspects of the process and double-check the results. 

How Does Marginal Relief Work?

A company taxed for its profits between £50,000 and £250,000 gets a reduced corporation tax bill through the marginal rate relief. The marginal relief bridges the gap between the lower and upper thresholds, allowing eligible businesses to pay lower than the main rate of 25%. 

The marginal relief for corporation tax rates associated companies work by reducing the profits between the upper and lower limits for short accounting periods and is based on how many associated companies the business has. 

How Does Marginal Relief Work

This means that the more associated companies a business has, the more the thresholds will get adjusted and divided. This moves the business to the lower threshold, benefiting from the adjusted reduced rates.  

Note that ring-fence companies have different rates. HMRC offers an online calculator to help businesses work out how much marginal relief they can get. For more accurate results, working with a tax expert is highly recommended.  

There are many other ways to reduce corporation tax. Claiming tax-deductible expense is a substantial relief to businesses with qualifying expenditures. Read our comprehensive guide on capital allowances, which explores all the latest allowances applicable to the 2024/25 tax year. 

What Is Corporation Tax on Chargeable Gains?

There are several ways to calculate corporation tax on chargeable gains to ensure accurate value. Hiring tax accountants will ensure businesses get the most accurate results.

What Are the Special Corporation Tax Regimes?

Aside from the ring fence corporation tax, otherwise called the oil and gas company regime, other sectors (and very large companies) in the UK get a separate tax treatment, especially on the aspects of tax avoidance, R&D credits, and others. They include the following: 

Life Insurance Companies

The life insurance sector follows different corporation tax rates and rules for calculating profits. 

Tonnage Companies

Companies operating qualifying ships can opt for Tonnage Tax, which calculates profits based on the net tonnage of ships rather than traditional profits. This election must be made within specific timeframes, with recent changes extending the entry period and adjusting capital allowances. 

Banking Companies

Banks face a supplementary tax of 3% on profits over GBP 100 million starting April 2023, down from the previous 8%. Restrictions apply to loss utilisation based on when the losses occurred. 

Real Estate Investment Trust (REIT) Companies

UK REITs are exempt from UK tax on rental income and gains from qualifying property rentals. Profits from non-property rental activities are taxed normally, and investors are taxed on distributed rental income, with possible exemptions and reclaim options depending on their tax status and double tax treaties. 

Qualifying Asset Holding Companies (QAHCs)

Introduced in April 2022 and amended in 2023, the QAHC regime aims to remove tax barriers for UK holding companies. QAHCs benefit from exemptions on gains from certain disposals, profits from overseas property, and modified rules for interest deductions, among others. 

Residential Property Developer Tax (RPDT) Companies

Effective from April 2022, the RPDT applies a 4% tax on annual profits exceeding GBP 25 million from residential property development, targeting companies or groups engaged in this trade.
