The Cayman Islands Economic Substance regime, set out in the International Tax Co-operation (Economic Substance) Act, requires every “relevant entity” carrying on a “relevant activity” to demonstrate adequate operational substance — people, premises, expenditure and decision-making — in the Cayman Islands. It applies to Cayman exempted companies, LLCs, LLPs and (since 30 June 2021) general partnerships, exempted limited partnerships and foreign limited partnerships, except where they are domestic companies, investment funds, or tax resident outside the Islands.
The economic substance test
Under the Act, a relevant entity carrying on a relevant activity must (i) conduct the core income generating activities (“CIGA”) for that activity in Cayman; (ii) be directed and managed in the Islands — typically including board meetings of adequate frequency with a quorum present in Cayman and strategic decisions recorded in the minutes; and (iii) have adequate operating expenditure, qualified employees or personnel, and physical premises in the Islands. The Tax Information Authority (“TIA”) administers the regime, supported by the Department for International Tax Cooperation (“DITC”).
Which entities are in scope
A “relevant entity” is a Cayman company (other than a domestic company), LLC, LLP, general partnership, limited partnership, exempted limited partnership, foreign limited partnership, or foreign company registered in Cayman — provided it is not an investment fund and is not tax resident outside the Islands. Partnerships were brought into scope by the International Tax Co-operation (Economic Substance) (Amendment of Schedule) Regulations, 2021, which came into force on 30 June 2021.
Who is excluded
Three categories sit outside the substance test: domestic companies (not part of an MNE Group, carrying on business only in the Islands and complying with the Local Companies (Control) Act or Trade and Business Licensing Act); investment funds, as defined in the Act; and entities tax resident in another jurisdiction with corporate income tax. Excluded entities still have notification obligations.
Reporting in two stages
Every Cayman entity required to file an Annual Return files an annual Economic Substance Notification (“ESN”) as a prerequisite to its Annual Return. Relevant entities carrying on a relevant activity must additionally file an Economic Substance Return (“ESR”) via the DITC Portal within 12 months of the end of each financial year.
Whether the regime applies to a particular Cayman vehicle is a fact-specific question that turns on activity, structure and tax residence.

FAQs
The Tax Information Authority (TIA) administers the International Tax Co-operation (Economic Substance) Act, supported by the Department for International Tax Cooperation (DITC). Filings are made via the DITC Portal and the General Registry’s Corporate Administration Platform (CAP).
Yes. Since the Amendment of Schedule Regulations came into force on 30 June 2021, general partnerships, limited partnerships, exempted limited partnerships and foreign limited partnerships are all relevant entities — unless they are investment funds, domestic partnerships, or tax resident in a jurisdiction with corporate income tax.
No. The Act does not introduce any tax in the Cayman Islands. It imposes operational substance, notification and reporting obligations, with civil penalties for non-compliance and ultimately strike-off.
