[Media Release-MFEM] International Company Update



Revenue Management Division

The purpose of this month’s message for international companies (ICs) registered in the Cook Islands is to ensure that sufficient notice is published regarding the recent changes to taxation of ICs in the Cook Islands and associated tax obligations. This update is part of a series of such monthly updates planned for 2021 as ICs, their intermediaries and the Revenue Management Division (RMD) work towards a well informed and efficient integration for ICs into the Cook Islands tax system.

RMD anticipates that around 800 existing ICs need to become familiar with newly acquired obligations by 1 January 2022 and shortly thereafter.

New tax obligations and residency rules for international companies

The International Companies (Removal of Tax Exemption) Amendment Act 2019 came into force on 17 December 2019 thereby removing tax exemptions for ICs; and with further amendments provided by the Income Tax Amendment Act 2019; ICs become resident for tax purposes in the Cook Islands and subject to the Cook Islands Income Tax Act 1997.

These new tax obligations require ICs to register with the Revenue Management Department (RMD) by applying for a RMD tax number (RMD Number). The new tax obligations also mean that ICs are required to assess their Cook Islands taxable income for each income year, calculate any tax to pay, file company tax returns (including NIL returns along with financial statements), and make any payments to RMD by the appropriate due dates.

The new tax obligations apply with immediate effect to ICs incorporated after 17 December

2019, whereas ICs incorporated before 17 December 2019 have been provided a transition period (also known as a grandfathering period).

Transition period

A transition period (also known as a grandfathering period) is provided for ICs existing as at 17 December 2019 so that tax exemptions are removed on 31 December 2021. ICs that qualify for the transition period need to take note that this transition period does not cover income derived from newly acquired assets or new business activities started after 17 December 2019 by the IC.

The transition period means that for ICs existing as at 17 December 2019 the registration with RMD, reporting of income and filing of tax returns apply from 1 January 2022 (except for income derived from newly acquired assets or new business activities from 17 December 2019).

Registration and applying for a Cook Islands tax number

International companies that are not covered by the transition period are required to make an application for a RMD Number within 28 days of a new business activity (such as incorporation). International companies that are covered by the transition period are required to make an application for a RMD Number on or before 1 January 2022.

Application for a RMD Number is made by completing and filing an RM2 form (along with relevant evidentiary documents) with RMD. The RM2 may be downloaded from the RMD website selecting Forms and Guides, then Tax Return and Registrations, then Registrations tab, then select Business Application – RM21. Important information that RMD requires includes the following information:

ü Register of Directors and Secretary (both resident and non-resident).

ü Register of members and shareholders (both resident and non-resident).

ü Certificate of registration.

The completed RM2 and any enquires should be sent to
