Cook Islands trust tax and reporting rules

Cook Islands tax treatment of trusts

The International Trusts Act 1984 is the principal Cook Islands statute for international trusts. How Cook Islands tax applies to a particular trust depends on the terms of the Act and the facts of that trust.^[1][2]

Legislation and regulations provide for automatic exchange of tax information under the Common Reporting Standard, and financial institutions register and submit CRS reports through the Revenue Management Division's portal. That is reporting by financial institutions, not a trust income tax calculation. The Cook Islands Ministry of Finance and Economic Management also lists income tax agreements with New Zealand and Australia covering certain income of individuals.^[2]

For a U.S. person who funds a Cook Islands trust, the local tax position rarely decides the U.S. result. The grantor trust and foreign trust rules summarized below apply whichever way Cook Islands law treats the trust.^[5]

IRS reporting for U.S. persons connected to a foreign trust

The IRS describes a U.S. person as including a U.S. citizen or resident, and says that U.S. persons who create a foreign trust or transact with one can have U.S. income tax and information reporting obligations. The connection and transaction determine which requirements may apply.^[5]

Form 3520 applies to specified events involving a foreign trust. The IRS lists creating or transferring money or property to a trust, making a loan to it, receiving a distribution, or receiving uncompensated use of trust property among the reportable connections.^[5]

A U.S. person treated as the owner of a foreign trust under grantor trust rules is generally taxed on that trust's income. The IRS describes a Foreign Grantor Trust Owner Statement that carries information about trust income for the owner's U.S. income tax return.^[5]

The IRS says a U.S. owner must ensure the foreign trust timely files Form 3520-A and provides required annual statements to U.S. owners and beneficiaries. If the trust does not file, the U.S. owner files a substitute Form 3520-A attached to a timely Form 3520 and furnishes the statements.^[5]

For a U.S. beneficiary receiving a distribution from a foreign nongrantor trust, the IRS says the beneficiary reports a share of distributable net income. The type of trust statement relevant to the distribution depends on whether the trust is a grantor or nongrantor trust.^[5]

The IRS instructions say Form 3520 is generally due on the fifteenth day of the fourth month after the U.S. person's income tax year ends. They give a sixth-month filing date for qualifying U.S. citizens or residents living and working outside the United States. If an extension to file the income tax return is granted, the Form 3520 deadline extends to the fifteenth day of the tenth month after the tax year ends.^[6]

Form 3520-A is generally due by the fifteenth day of the third month after the foreign trust's tax year ends. When that day falls on a weekend or legal holiday, the due date moves to the next business day. A substitute Form 3520-A attached to the U.S. owner's Form 3520 follows the Form 3520 due date instead.^[6]

The IRS materials also identify possible reporting under FinCEN Form 114 for foreign bank accounts and Form 8938 for specified foreign financial assets. Whether those forms apply depends on the facts described by the relevant reporting rules.^[6]

The United States has no bilateral income tax treaty with the Cook Islands.^[4]
