Economic Substance Rules: What They Require and Who They Apply To

Why the rules exist

International tax standards now expect a company that benefits from a preferential tax treatment to have a substantial economic presence where it is based, and an explicit link between its income and real activity there. Hong Kong's Inland Revenue Department gives that as the reason for its own rules, adopted in line with guidance from the European Union (Inland Revenue Department, as of November 2026).

Several jurisdictions that charge little or no corporate tax introduced economic substance laws in response. They work in a similar way: a company that carries on a listed relevant activity must show that it is managed and run locally, with enough people and premises for what it does.

Cayman Islands

Cayman's International Tax Co-operation (Economic Substance) Act lists nine relevant activities: banking, distribution and service centre, financing and leasing, fund management, headquarters, holding company, insurance, intellectual property and shipping business. Investment fund business is excluded (Cayman Islands legislation, 2026 revision, as of November 2026).

For each activity the Act defines core income-generating activities that must be carried on in the Cayman Islands. For banking, for example, they include raising funds, managing risk, taking hedging positions and providing loans or other financial services to customers (Cayman Islands legislation, 2026 revision, as of November 2026).

British Virgin Islands

The BVI's Economic Substance (Companies and Limited Partnerships) Act applies a lighter test to a pure equity holding entity, one that only holds equity participations and earns dividends and capital gains. It has adequate substance if it complies with its obligations under the BVI Business Companies Act and has adequate employees and premises in the BVI for holding, and where it manages them, managing those participations (BVI Financial Services Commission, as of November 2026). A company that does more than hold shares has to meet the fuller test for its activity.

United Arab Emirates

The UAE no longer requires economic substance reporting. The Ministry of Finance announced on 14 October 2024 that Cabinet Decision No. (98) of 2024 cancelled the reporting requirements for financial years ending after 31 December 2022, in line with the introduction of federal corporate tax. Obligations for earlier years remain (Ministry of Finance, as of November 2026). Our UAE company page covers the company side.

Hong Kong

Hong Kong has no general substance law, but its rules for foreign-sourced income use the same idea. Since 1 January 2023, foreign-sourced dividends, interest, intellectual property income and equity disposal gains received in Hong Kong by a member of a multinational group are taxable unless an exception applies, and the economic substance requirement is one of them (Inland Revenue Department, as of November 2026). Our explainer on territorial taxation covers the wider system.

Substance beyond the statutes

Even where no substance law applies, the same question decides other things. Where a company is managed can decide where it is tax resident, as our guide to company redomiciliation explains, and a director who only signs what is decided elsewhere does not show that decisions are taken locally; see our explainer on nominee directors.

In our experience substance also matters for banking. A company with local directors who take the decisions, proper bookkeeping and a business that fits its location is easier to bank than a registration with nothing behind it. When you choose a jurisdiction, plan the substance you can actually provide; our Global Structuring desk builds that into the plan, and our BVI company page covers the BVI side.

Frequently asked questions

Do economic substance rules apply to every BVI or Cayman company?

No. They apply to companies that carry on one of the listed relevant activities, such as holding, financing, fund management or intellectual property. Each activity has its own test.

Does a holding company need an office and staff?

In the BVI a pure equity holding entity meets a reduced test: it must comply with its obligations under the BVI Business Companies Act and have adequate employees and premises in the BVI for holding its participations.

Are the UAE economic substance rules still in force?

Reporting was cancelled for financial years ending after 31 December 2022, by Cabinet Decision No. (98) of 2024. Companies remain responsible for obligations from earlier years.

Does a nominee director provide substance?

Not by signing alone. Substance means decisions are taken and work is done locally by people who are able to do it.
