The Economic Substance Regulations did not apply to every business. They applied to those carrying on defined relevant activities, and identifying whether a business fell into one of those categories was the first and most important question under the regime. This still matters for the legacy years the regulations covered, from 2019 to 2022, because a business needs to know whether it was in scope for those periods. Here is what the relevant activities were and how scope worked.
Scope started with the activity
ESR was activity-based. A company was in scope only if it carried on one of the listed relevant activities and earned income from it; a business doing none of them was outside the regime entirely. This meant the threshold question was never about size or licence type alone but about what the business actually did. Many companies spent effort determining whether their activities, sometimes incidental to their main business, brought them into scope.
The relevant activities
The defined categories were specific and are worth recognising, since they still frame the legacy analysis.
| Relevant activity | Broad nature |
|---|---|
| Banking and insurance | Regulated financial services |
| Investment fund management | Managing funds for others |
| Lease-finance | Providing credit or finance |
| Headquarters | Central management services to a group |
| Shipping | Operating ships in international traffic |
| Holding company | Holding shares in other companies |
| Intellectual property | Exploiting IP assets |
| Distribution and service centre | Group distribution or services |
Substance expected in proportion to the activity
Not every relevant activity carried the same weight of substance. Some, notably intellectual property and, at the other end, pure holding companies, were treated distinctively: high-risk IP arrangements faced heightened scrutiny, while holding companies with only passive shareholdings faced a lighter, reduced substance test. The regime tried to match the substance expected to the nature and risk of the activity, rather than applying an identical bar to a bank and a passive holding company.
ESR scope turned on the activity, not the size or licence. The first question was always whether the business carried on a listed relevant activity, and that same question frames any legacy analysis for 2019 to 2022.
Incidental activities caught businesses out
A recurring difficulty was that a business might carry on a relevant activity almost by accident, as a small part of a wider operation. A trading company that also held shares in a subsidiary, or licensed some intellectual property, could find itself in scope for that slice of activity even though it did not think of itself as a holding or IP business. This is why the scope analysis had to be done carefully rather than dismissed, and why some businesses that assumed ESR did not apply to them were, in fact, in scope for part of what they did.
What to do about it
For the legacy years, check honestly whether your business carried on any of the relevant activities, including incidentally through holdings, intellectual property, or group services, not just as its headline business. If it did, confirm that your ESR position for those periods was handled correctly. The activity-based scope that defined ESR is the same lens you apply to any remaining legacy question, and doing that analysis properly is how you establish whether you have anything to address for the years the regime covered.
