What is a close investment-holding company?

A close investment-holding company (CIHC) is a financial entity that primarily holds investments in other businesses, emphasising long-term growth and capital appreciation. This structure allows investors to exert influence over their portfolio companies, guiding them towards success.

Understanding the dynamics of a CIHC is essential for businesses seeking strategic investment opportunities and long-term financial stability. It involves careful consideration of factors such as portfolio diversification, risk management, and compliance with regulatory standards. As businesses navigate this financial landscape, they can make informed decisions that align with their overarching objectives and financial aspirations.


From 1 April 2023, there is a small profits rate of 19% for companies with profits of less than £50,000. Companies with profits between £50,000 and £250,000 pay tax at the main rate (of 25%), reduced by a marginal relief. This provides a gradual increase in the effective Corporation Tax rate.

In addition to this, if a company is classed as a close investment holding company (CIHC) then the tax rate is automatically the main rate of tax regardless of the level of profits. A CIHC is where a company is controlled by five or fewer participators, and it does not exist wholly or mainly for the purpose of:

  • Trading commercially
  • Investing in land, estates or interests in land for letting
  • Acting as a holding or service company within a group which exists wholly or mainly to trade or invest in land for letting.

One key thing to note is that companies that make investments in land, estates or interests in land to connected companies (i.e., those under common control) will be specifically treated as close investment holding companies even if all transactions are at commercial rates / market value.
