Associated Companies for Corporation Tax 2023

Associated Companies for Corporation Tax – New Rules from April 2023 


The rules around corporation tax changed on 1 April 2023. The amount of corporation tax that a company will pay will depend on the level of its profits, and also whether or not it has any associated companies.

From 1 April 2023, companies with profits below £50,000 will pay corporation tax at the small profits rate of 19% whilst companies whose profits exceed the upper limit of £250,000 will pay corporation tax at the main rate of 25%.

Where two or more companies are “associated” with each other, the Corporation tax limits are divided by the number of companies concerned.

What is an Associated Company?

A company is an associated company of another at any time when:

  • One of the two has control of the other or
  • Both are under the control of the same person or persons

Companies are considered associated for the full accounting period, even if they are only associated for part of that period. Associated companies can also include both UK and Non-UK tax resident companies. 

Dormant Companies which are not carrying on any trade or business are excluded from the associated company calculation.

When considering whether a person has control over more than one company, the most common test for “control” is the voting power of a shareholder. In a simple case, where each of the company’s shares carries one vote, any person or persons who own more than 50% of the shares will “control” the company.

It is important to understand the number of associated companies as soon as possible to estimate tax liabilities. If you are forecasting to produce significant profits for your company and you have one or more Associated Companies, you may wish to considering restructuring your activities to minimise any loss of marginal relief.
