Economic substance rules for offshore companies explained

For decades, a company in a low-tax centre could exist largely on paper: a registered office, a registered agent and little else. That era has ended. Economic substance rules now require many companies in these centres to show that they genuinely carry on their business where they are registered, with people, premises and decisions to match.

AT Express is headquartered in Cyprus, with offices in the United Kingdom, Hong Kong, China, Vietnam and Singapore. We help clients plan structures that can meet these requirements, and this article explains how the rules work.

Where the rules come from

The rules grew out of international work on harmful tax practices. The OECD’s Forum on Harmful Tax Practices developed a standard on substantial activities, and the European Union assessed jurisdictions with no or only nominal corporate tax against a criterion requiring that profits be matched by real economic activity. Jurisdictions that did not respond risked being placed on the EU list of non-cooperative jurisdictions.

Most established offshore centres legislated in response. The Cayman Islands Department for International Tax Cooperation notes that the Cayman Economic Substance Act came into force on 1 January 2019, developed in collaboration with the OECD’s Forum and the European Commission’s services. The British Virgin Islands administer their rules through the International Tax Authority.

Which companies are affected

The rules apply to companies that carry on one or more relevant activities. While the details differ between jurisdictions, the categories generally include:

• banking, insurance and fund management;
• finance and leasing;
• headquarters business;
• shipping;
• holding business, usually with a reduced test for pure equity holding companies;
• intellectual property business; and
• distribution and service centre business.

A company that carries on none of these activities may have only a simple annual notification to make. A company that does must meet the substance test for each relevant activity.

What the test asks

In broad terms, a company carrying on a relevant activity must show that:

• it is directed and managed in the jurisdiction, with board meetings held there at an adequate frequency and with directors who have the necessary knowledge;
• its core income-generating activities are carried out there, by its own staff or by a local service provider under its supervision; and
• it has adequate employees, premises and expenditure in the jurisdiction, proportionate to the activity.

Intellectual property businesses face the most demanding rules, and in some jurisdictions a presumption of non-compliance where the intangible assets were acquired from related parties or are used outside the jurisdiction. Companies report annually, usually through their registered agent, and the information may be exchanged with the tax authorities of the owners’ and parent companies’ countries.

How substance fits into the wider choice of offshore jurisdiction is covered on our page on offshore company formation.

Consequences of falling short

Companies that fail the test face financial penalties, which typically escalate for repeated failures, and spontaneous exchange of information with the relevant foreign tax authorities. In serious cases, authorities may strike the company from the register. Failure also makes banking far harder: banks increasingly ask how a company meets the substance requirements, as our article on bank accounts for offshore companies explains.

Substance beyond offshore centres

Substance matters in onshore jurisdictions too. The UAE’s regime for qualifying free zone persons requires adequate substance in the UAE, as our UAE free zone corporate tax guide describes. Tax treaties increasingly deny benefits to companies without a genuine business purpose, and many countries treat a company as resident where it is actually managed. The OECD/G20 Pillar Two rules, which ensure that large multinational groups pay a minimum level of tax, reinforce the same direction of travel.

Planning for substance

• Identify early whether the company will carry on a relevant activity.
• Where it will, budget realistically for directors, staff or an outsourced provider in the jurisdiction.
• Hold and minute board meetings in the jurisdiction, with real decisions taken there.
• Keep records that demonstrate the activity, not just describe it.
• Reconsider the jurisdiction if the substance required is impractical: an onshore company may be simpler, as our article on offshore and onshore companies explains.

Our pages on the British Virgin Islands, the Cayman Islands and the Seychelles set out how each jurisdiction approaches the rules, and our page on international tax planning explains how we coordinate advice with licensed specialists.
