Does Cayman Islands require economic substance?

Cayman Islands does require economic substance in certain cases, but not for every company. Under the International Tax Co-operation (Economic Substance) Act, a relevant entity that carries on a relevant activity is required to satisfy the economic substance test in relation to that activity.

This means the correct question is not whether Cayman has substance rules, but whether a specific entity falls within scope. The law applies by reference to concepts such as “relevant entity” and “relevant activity,” so the answer depends on the company’s structure, tax status, and income-generating business activity. In practice, some entities will be in scope, while others may be out of scope or subject to lighter requirements depending on their classification.

For example, a passive holding vehicle may face a different practical analysis from a company conducting a more active relevant business. A business involved in activities that generate income within the categories defined by the law needs to review whether management, expenditure, and core income-generating activities are adequately connected to Cayman.

Strategically, Cayman can still work well for international structuring, but economic substance must now be reviewed at the planning stage rather than treated as an afterthought.
