Benefits and Requirements
To benefit from the Substantial Shareholdings Exemption (SSE), businesses can enjoy tax savings by reinvesting their profits without the burden of Capital Gains Tax (CGT), improving their overall financial health.
This exemption encourages investment by allowing companies to dispose of shares tax-efficiently, which in turn encourages businesses to invest in new ventures and expand their operations.
Tax savings under SSE can be substantial, enabling companies to focus on growth and development rather than tax liabilities.
To qualify for SSE, businesses must meet specific criteria, including owning at least 10% of the ordinary share capital of the subsidiary for a continuous period of 12 months within the two years before the disposal.
The selling company must also be a qualifying trading company or a member of a qualifying trading group, and the company whose shares are being sold must meet the trading status criteria.
Businesses must ensure that both the seller and the subsidiary primarily engage in trading activities, such as manufacturing, retail, or services, rather than investment activities.
Here are the key SSE requirements:
Meeting these requirements is crucial to unlocking the full potential of SSE benefits, so businesses should consult with tax professionals to ensure compliance.

Anti-Avoidance
The SSE regime contains anti-avoidance provisions designed to prevent abuse of the exemption.
These provisions are specifically aimed at catching very particular activities, and HMRC doesn't expect them to be triggered often.
The legislation sets out that SSE won't apply if an untaxed gain arises within a company due to a disposal of shares, and before that gain arose, the company acquired control of the target company.
Or, the same person(s) acquired control of both companies.
There's also a provision for a "significant change in the trading activities" of the target company, which must have occurred when it was controlled by the investing company, or both companies were controlled by the same person or persons.
