A Close Investment-Holding Company (CIHC) is a UK close company that does not qualify for one of the statutory exemptions from the CIHC rules. These companies typically hold investments and derive income from sources such as dividends and interest rather than carrying on an active trade.
CIHC status is important because it determines whether a company qualifies for lower rates of Corporation Tax. Companies that fall within this definition are typically taxed at the main Corporation Tax rate, regardless of profit level.
This guide explains how CIHCs are defined, how they are taxed, and what this means in practice for UK companies and shareholders.
Close Investment-Holding Company at a Glance
- Applies to UK close companies with mainly investment income
- Typically excludes active trading businesses
- Subject to the main Corporation Tax rate
- Common in investment and property holding structures
- Important for tax planning and structuring decisions
Why Does CIHC Status Matter?
CIHC status directly affects the amount of Corporation Tax a company pays.
In practical terms:
- CIHCs are not eligible for the small profits Corporation Tax rate
- They are usually taxed at the main Corporation Tax rate
- This can increase the overall tax burden on profits
For business owners and investors, this makes it important to understand whether a company’s activities fall within HMRC’s definition of an investment holding company.
It can also influence decisions around how profits are generated, retained, and distributed within a company.

What Makes a Company a Close Investment-Holding Company?
A company is generally classified as a CIHC if it meets the following conditions:
- It is a close company (controlled by five or fewer participators or shareholders)
- Its income is mainly derived from investments or passive sources
- It is not actively trading or carrying on a commercial business
- It does not fall within specific exemptions under HMRC rules
Property rental businesses require particular care. Receiving rental income does not automatically make a company a CIHC. In many cases, companies that let property to unconnected third parties can fall within an exemption from the CIHC rules.
What is a Close Company?
A close company is broadly one that is under the control of:
- Five or fewer shareholders, or
- Any number of shareholders who are also directors
Most owner-managed UK companies fall within this definition.
CIHC vs Trading Company: What’s the Difference?
Understanding the distinction is key for tax purposes.
| Feature | CIHC | Trading Company |
|---|---|---|
| Main income | Investment income | Trading income |
| Activity | Passive | Active business operations |
| Tax treatment | Main rate only | May qualify for lower rates |
| HMRC classification | Investment company | Trading company |
A trading company generating income through goods or services will generally not be treated as a CIHC.
What Does CIHC Status Mean for Corporation Tax?
CIHC status has clear implications for how profits are taxed.
In most cases:
- The company will not qualify for the small profits rate
- It will not benefit from marginal relief
- Profits will be taxed at the main Corporation Tax rate
This means that even relatively small companies could face higher tax bills if they fall within the CIHC definition.
The classification, therefore, has a direct impact on:
- Overall tax efficiency
- Effective tax rates
- Cash retained within the business
How Do You Know if Your Company Is a CIHC?
You can assess this by reviewing your company’s income and activity.
Ask:
- Does the company primarily earn investment income such as dividends or interest, rather than trading income?
- If the company receives rental income, does it qualify for a property letting exemption under the CIHC rules?
- Is the company controlled by a small group of shareholders?
- Is there limited active trading?
If the answer to most of these is yes, the company may fall within CIHC rules.
Where there is a mix of activities, classification can become more complex and may require detailed review.
Factors That Affect CIHC Classification
- Income Mix – The proportion of passive versus trading income is key.
- Business Activity – Active operations support trading status.
- Company Structure – Different entities within a group may be treated differently.
- HMRC Interpretation – The distinction between trading and investment can depend on specific facts and circumstances.
How Can You Manage CIHC Status?
Managing CIHC status involves reviewing how a company operates and generates income.
Key actions include:
- Maintaining trading activity
Ensuring income primarily comes from commercial operations - Reviewing income sources
Limiting reliance on passive income - Structuring appropriately
Separating trading and investment activities where needed - Monitoring changes
Classification can change as business activity evolves
Any changes should be considered alongside broader tax planning objectives
Common Misunderstandings About CIHCs
- All property companies are CIHCs – Incorrect. A company that receives rental income from property let to unconnected tenants may be exempt from the CIHC rules, depending on the facts and circumstances.
- Small companies automatically receive lower tax rates – CIHCs are excluded from these rules
- CIHC rules only affect large businesses – They often apply to smaller, owner-managed companies
When Should You Seek Advice on CIHC Status?
It may be appropriate to seek advice where:
- A company has mixed trading and investment income
- You are setting up an investment or holding company
- There are changes in how income is generated
- You are reviewing tax efficiency within a group

Conclusion
A Close Investment-Holding Company is a specific UK tax classification that determines how certain companies are taxed.
Where a company primarily earns investment income and meets the close company criteria, it is likely to be taxed less favourably than a trading business. Understanding this distinction is essential for managing Corporation Tax exposure and maintaining an efficient structure.
Regular review of company activities and income can help ensure that tax treatment remains appropriate over time.

You can assess this by reviewing whether the company mainly earns passive income, whether it is actively trading, and whether it is controlled by a small group of shareholders. If most income is investment-based, it may be a CIHC.
