• Marginal Relief is available for a profit of between £50,000 and £250,000.

If you have a business that is associated with other businesses (i.e., the businesses that fall under the same ownership), the profit limits are split among the associated companies. This prevents big companies from dispersing profits among many small firms to reap in a way that is unfairly benefits from lower tax rates. The tax relief for marginal corporations permits a gradual increase in your tax-effective rate depending on the range of your profits.

Corporation Tax Rates for Limited Companies

The financial year begins on April 1, 2025. UK Corporation tax rates are set out. They are based on the new changes that were introduced in April 2023:

Small Profits Rate 19% applies to businesses that have tax-deductible profits in the range of £50,000 or less. The small corporation tax rate is intended to reduce the burden of tax on new or smaller businesses.

Main Rate: This higher rate of 25% applies to businesses with taxable profits that exceed £250,000. This is a rise for companies with larger revenues as compared to the previous year.

Marginal Relief Rate Organizations that have tax-deductible profits that fall between £50,000 and £250,000 profit by a system called Marginal Relief.

This will ensure that the companies within groups are not able to artificially share profits to take advantage of the low profits across multiple companies. The interdependence of the organization and its economics is are crucial factor when it comes to determining related firms.

A limited company can be described as a distinct company structure that is registered with Companies House, granting it its legal entity that is distinct from its proprietors, who are known by the name of shareholders.

This separation of ownership provides limited liability, which is a major advantage in that the personal assets of owners are usually protected if the company faces financial challenges or incurs debt. It is a structurally independent entity, which means that the business can sign agreements, possess property, and, if necessary, incur obligations in its name instead of that of its directors or shareholders.
