Like other offshore landscapes, Cayman Islands have also been affected by the approaches of OECD and the European Union (EU) regarding fair taxation. Cayman Economic Substance (ES) is now an essential part of any in-existence or newly incorporated entities in the Islands.

In this article, BBCIncorp gives detailed guidance on Cayman Islands Economic Substance Requirements – who is covered, how to comply with the Economic Substance law, and other related matters.

1. Introduction to Cayman Economic Substance Rules

Having drawn much attention probably was the implementation of the OECD Forum on Harmful Tax Practices, aka FHTP. The forum came with the global standard regarding substantial activity requirement to no or only nominal tax jurisdictions in November 2018.

As a member of the OECD BEPS Inclusive Framework, Cayman Islands were among the very first ones to initiate their domestic law to meet the economic substance standard.

The International Tax Co-operation (Economic Substance) Law (2020 Revision), or Cayman “ES Act”, entered into force on 1 January 2019. The Act was then amended several times to further modify the requirements of ES notification, sharing of information, and other issues.

The Cayman ES (Amendment) Law, 2020 (Law 7 of 2020) published on 12 February 2020 is currently the latest version of the ES Act.

Other supplemented regulations and guidance, namely the Guidance on ES for Geographically Mobile Activities, and Cayman ES Regulations, 2020 were thereafter issued, on 13 July 2020 and 11 August 2020 respectively.

Accordingly, ES law requires in-scope entities with geographically mobile activities in the Cayman Islands to demonstrate economic substance as an annual requirement. For each relevant activity as prescribed in the law, entities must satisfy an economic substance test, including the CIGAs test, direction, and management test, and adequacy test.

Concerning filing obligations for those entities, the two main duties are to submit ES notification to the Authority and to file an ES return to the Authority.

The Tax Information Authority (the ‘Authority’), a functional unit of the Department for Internal Tax Co-operation (DITC) in the Cayman Islands, is responsible for supervising the ES law in the Cayman Islands and guarantee compliance with the law.

In what follows, we will delve into the ins and outs of how to comply with Cayman Islands Economic Substance Requirements!

2. Entities that must comply with Cayman ES

2.1. In-scope entities under ES Law

Pursuant to Cayman ES Act, in-scope entities, or relevant entities under ES law refer to:

  • A company incorporated in accordance with the Companies Law (2020 Revision), or
  • A limited liability company (LLC) registered according to the Limited Liability Companies Law (2020 Revision); or
  • A limited liability partnership (LLP) registered according to the Limited Liability Partnership Law, 2017; or
  • A company incorporated outside of the Cayman Islands and registered in accordance with the Companies Law (2020 Revision).

2.2. Entities excluded from ES Law

There are certain out-of-scope entities, and these cases will NOT be required to observe the ES test in the Cayman Islands. Excluded cases are:

  • A domestic company; or
  • A company as an investment fund; or
  • A company as a tax resident in an overseas jurisdiction

To be regarded as a tax resident in another jurisdiction outside Cayman, your company should provide evidence to the Authority that the company is subject to corporate tax on all of its income in another jurisdiction due to its tax residence, domicile, or other similar reasons.

And this same requirement goes for foreign branches of a relevant entity.



You own a Cayman incorporated company conducting on a relevant entity from a Hong Kong branch. Since Hong Kong branch pays corporate taxes on all of the branch’s income in Hong Kong relating to the relevant entity, the branch is regarded as a tax resident outside Cayman.

2.3. Relevant activities under ES Law

There shall be a filing obligation imposed on each relevant entity conducting on relevant activity. Like other legal jurisdictions implicating ES law, 9 relevant activities in respect of the OECD and EU standard involves:

  • Banking business
  • Distribution and service center business
  • Financing and leasing business
  • Fund management business
  • Headquarters business
  • Holding company business
  • Insurance business
  • Intellectual property business
  • Shipping business

It is worth mentioning that an entity is considered to engage in a relevant activity NOT just based on relevant income from that activity. “Passive relevant income” is the income generated without participation in the business activity of the recipients.

Dividends, interest, royalties, or rental property are typical examples of this type of income. Activity with passive relevant income can be regarded as a relevant activity.

3. Cayman Economic Substance guidance: ES test and Reduced ES test

3.1. Cayman ES test

In accordance with Cayman ES Law, every relevant entity carrying on a relevant activity must satisfy the economic substance test. Note that if your company has two or more relevant activities, it is required that the ES test must be demonstrated with respect to each relevant activity.

The question is: what is included in an Economic Substance Test under Cayman ES Law?

In-scope entities conducting relevant activities will meet the ES test in Cayman if the below three conditions are met:

  • Direction and management test, which means the entity is directed and managed appropriately inside the Islands in respect to its relevant activity;
  • Adequacy test, meaning the entity must guarantee:
    • Having an adequate level of expenses for operating the relevant activity in the Islands;
    • Having an adequate number of appropriate employees in relation to the relevant activity in the Islands;
    • Having an adequate place of business and specific equipment in the Islands.
  • CIGAs test, meaning the entity is carrying out certain Core Income Generating Activities inside the Islands in respect to its relevant activity.

CIGAs refer to activities playing a central role to a relevant entity regarding generating relevant income. Importantly, CIGAs must be conducted in the Cayman Islands.

It should also be noted that the Cayman government does allow a relevant entity to outsource its CIGA to a third party. Still, the entity must guarantee control of CIGA in the Islands.

3.2. Reduced ES Test

Reduced ES test in the Cayman Islands is only applicable for pure equity holding companies.

Accordingly, a pure equity holding company can pass a reduced ES test if it meets the following criteria:

  • The company complies with relevant filing obligations as stated in the Companies Law (2020 Revision); and
  • The company has adequate employees and premises in the Islands for holding and managing equity participation in other companies.


HELO Co Ltd holds 100% of shares in the other three companies. It receives dividends on a yearly basis through this holding structure. HELO is considered to be an intermediary pure entity holding company in the Cayman Islands without engaging in any other different activity.

In this regard, HELO is a relevant entity conducting a relevant activity in the Islands. But, it would be subject to a reduced ES test instead of a much more complicated test of other relevant activities.

3.3. Other exceptions

Suppose you incorporated a relevant entity in the Cayman Islands, conducted one of nine relevant activities required to satisfy the ES test by the ES Law, but that activity generated no relevant income. In such a case, your entity would have no obligation to fulfill the requirement of an economic substance test.

Note, however, that following annual reporting duties under the Cayman ES Law is ineluctable. Your entity still must complete the ESN and ES return to the Authority, among which ES return will be filed as a “nil” one.

Further clarifications of Relevant income can be found in Section II.D of the Guidance.

4. Filing requirements under Cayman ES (What to report)

In accordance with Cayman Economic Substance Law, a relevant entity that carries on one or more relevant activities under the law must satisfy certain filing obligations. Particularly, these entities are required to:

  • Send a notification of Economic Substance to the Authority; and
  • File an Economic Substance Return to the Authority.

Keep in mind, the notification and the reporting are two key compliance duties for any relevant entity according to the Cayman Economic Substance guidance. And these must be done on an annual basis.

4.1. ES Notification

What ESN is. Economic Substance Notification (ESN) is an annual notification requirement for all entities, not excluding any legal persons registered with the General Registry. A key to mention is that ES notification acts as a sine qua non of filing the annual ES return for applicable entities.

How to file. Typically, there are two popular systems via which entities can file their ES notifications:

  • CAP system (The General Registry’s Corporate Administration Platform)
  • CBP system (Cayman Business Portal): applicable for certain cases. It should also be noted that those submitting ESNs on CBP will be asked to confirm whether they are connecting to a relevant activity.

Important update

According to the latest Practice Points on Economic Substance (11 Jan 2021 updated), entities with the financial year which starts in 2020 and in 2021 can now submit their ES notifications via CAP. Meanwhile, the submission gate for filing ESNs via CBP is currently only open for the financial year starting in 2020.

What to be included in ESNs. Entities should involve the following information when submitting their ESNs to the Authority:

  • Whether the entity is conducting a relevant activity;
  • Whether the entity is a relevant entity (in case the entity is connecting with a relevant activity);
  • When the entity is conducting a relevant activity and is NOT tax resident inside the Islands (below details will ONLY be required for those which has its owners classified as an immediate parent, ultimate parent, and ultimate beneficial owners (BO)):
    • Name, address, and other verification details of the entity’s immediate parent, ultimate parent, and ultimate BO;
    • Date from which the entity’s financial year ends; and
    • The jurisdiction where the entity is regarded to be tax resident, along with related supporting evidence
  • When the entity is a relevant entity conducting a relevant activity:
    • Date from which the entity’s financial year ends; and
    • Name, address of the representative who is in charge of notifying and providing the Authority with supporting documentation if required.

When to file. The deadline for ESNs submission is the same as the due date for filing the Annual Return, normally falling into 31 March annually. Note that the ES notifications will depend on your entity’s financial year.

4.2. ES Return

What ESR is. Relevant entities conducting a relevant activity must meet the requirements of ES test, and file an Economic Substance Return (ESR) to the Authority on a yearly basis. The main purpose of this reporting obligation is to identify if your entity satisfies the ES test.

How to file. Cayman ES Return, or simply a form, is done electronically via a DITC Portal (Department for International Tax Cooperation).

The link to access this portal will be emailed to the Responsible Person (can be your entity’s director or register office) confirmed on the ES notification. This Person is allowed to appoint other secondary users via the DITC Portal to help finish the filing obligation. Wish to get a sample of ES return for your reference? You can get it here.

What to be included in ES return. Below are fundamental documents that should be prepared when it comes to reporting to the Authority:

  • Type of relevant activity that the entity has conducted;
  • Amount and type of relevant income in relation to that activity;
  • Amount and type of costs, properties relating to that activity;
  • Information about premises, equipment, or property served for that activity in the Islands;
  • Number of qualified employees in relation to that activities;
  • Description of CIGAs in relation to that activity;
  • Information about any MNE Group (Groups with total consolidated revenue of at least US$850 million) (if applicable);
  • Other prescribed information as the case may be for that relevant activity falling into a high-risk or non-high-risk intellectual property business;
  • Additional documents that may be required (on a case-by-case basis).

When to file. The deadline for ESR submission is a 12-month period from ending the financial year starting on or after 1 January 2019. Due date for filing ES return has been extended to certain cases due to the impact of the COVID-19 pandemic.

What to report Financial year end date (for ES return purposes) New due date 
ES Return – All (IP business excluded) 31 Dec 2019 – 30 April 2020 30 April 2021
ES Returns From 1 May 2020 A 12-month period after the financial year end
ES Return – IP business
and Tax Resident Overseas (TRO)
31 Dec 2019 – 29 Feb 2020 28 Feb 2021
From 1 March 2020 A 12-month period after the financial year end

5. Exchange of information

agreement with electronic signature

Pursuant to the ES Law (2020 Revision), the Authority shall share information collected by the Authority under the Economic Substance Law with other competent authorities as per signed agreements and associated global standards.

Accordingly, the exchange of information would be conducted if the entity falls into the following cases:

  • The relevant entity failed to fulfill the ES test in respect of its relevant activities;
  • The relevant entity is related to a high risk IP business.

Be advised that information will also be shared between the Authority and the relevant authority of the jurisdiction in which the entity in question is proven to be a tax resident, and where the parent company, ultimate parent company, and ultimate beneficial owner of the relevant entity resides (as the case may be).

6. Non-compliance cases of Cayman Islands ES

Non-compliance with the ES test under Cayman Economic Substance Law can lead to a penalty of up to US$100,000.

Section 4(d), International Tax Co-operation (Economic Substance) (Amendment) Law, 2020 also clarified the fine of US$5,000 (plus US$500 for each day when the non-compliance continues) for those subject to ES test but then fail to comply with ES return submission during the prescribed time frame.

Furthermore, if one entity is determined to follow the ES test, but provides misleading information to the Authority during the process, that entity shall be subject to a financial penalty of US$10,000 or be jailed for 5 years, or even both (as the case may be).
