Mauritius Trust Tax and Reporting Rules

Mauritius legislation addresses trusts and trustee residence, and IRS guidance sets out what U.S. persons connected to foreign trusts report.

The Mauritius Trusts Act

The Trusts Act defines a trust through the trustee's fiduciary obligation over property and sets out the framework for creating and administering it. The Act defines a beneficiary as a person entitled to benefit, or someone for whom a power to distribute trust property may be exercised.^[1]

The Act defines a foreign trust by its proper law. A trust's proper law is generally the law expressed or intended in its terms, with closest connection as a fallback where those terms do not provide a governing law.^[1]

The place of administration, asset situs, and trustee residence or business are among the listed factors for determining a trust's closest connection.^[1]

A written instrument is required for most trusts created under the Act, subject to listed categories such as unit trusts and trusts arising by operation of law. The Act also addresses the trust instrument, trustees and their duties, as well as trustee powers.^[1]

Mauritius trustee requirements and administration

The Act defines a qualified trustee as a management company or another person resident in Mauritius who is authorised by the Commission to provide trusteeship services. This is a defined legal status, and it does not by itself establish how trust income is taxed.^[1]

A purpose trust must have at least one qualified trustee, an enforcer capable of enforcing its terms, and a successor enforcer provision. Its purpose must be specific, reasonable, and capable of fulfilment.^[1]

The Act provides for trustee appointments and acceptance, resignation or removal, and requires trustees to act together unless the trust terms provide otherwise. Trustees also hold statutory fiduciary duties concerning trust property and impartial conduct.^[1]

The legislation includes procedures for keeping and submitting trust accounts among the matters on which the Court may make orders.^[1]

Mauritius information reporting framework

The Mauritius Revenue Authority publishes the Common Reporting Standard, CRS regulations, guidance notes, and tax identification number and tax residency information.

The Mauritius Revenue Authority also publishes CRS implementation documents and reportable-jurisdiction materials.^[2]

Mauritius has a Model 1 FATCA intergovernmental agreement with the United States in force. Under FATCA, foreign financial institutions report financial accounts held by U.S. taxpayers or certain foreign entities.^[3]

U.S. reporting for a U.S. person connected to a foreign trust

The IRS defines a U.S. person to include a U.S. citizen or resident and explains that connections to foreign trusts can bring income tax consequences and information reporting obligations. The listed connections include creating or funding a trust, ownership under grantor trust rules, and receipt of trust distributions.^[5]

Form 3520 generally applies when a U.S. person creates or transfers property to a foreign trust, makes a loan, receives a distribution, or is treated as an owner under grantor trust rules. The instructions call for a separate Form 3520 for transactions with each foreign trust.^[5]^[6]

The IRS states that a U.S. person treated as owner under grantor trust rules is generally taxed on trust income. For a U.S. owner, Form 3520-A is the annual information return for a foreign trust with a U.S. owner, and owner and beneficiary statements provide information for U.S. reporting.^[5]

A U.S. beneficiary receiving a distribution from a foreign nongrantor trust generally reports the beneficiary's share of distributable net income. A U.S. beneficiary who receives no beneficiary statement reports the distribution under the default rules in the Form 3520 instructions.^[5]

For an individual U.S. person, Form 3520 generally falls due in the fourth month after the end of the person's tax year, with specified extensions. Form 3520-A is generally due in the third month after the foreign trust's tax year ends; a substitute attached to Form 3520 follows the Form 3520 due date. When that day falls on a weekend or legal holiday, the due date moves to the next business day.^[6]

The IRS explains that Form 3520-A must be timely filed by the foreign trust when a U.S. person is treated as its owner. If the trust does not file it, the U.S. owner files a substitute with Form 3520 and furnishes required annual statements.^[5]

Treaty and CRS context

U.S. income tax treaties can address specified income items, and treatment depends on the country and type of income.

Questions and answers

Does Mauritius's Trusts Act set a trust tax rule based on trustee residence?

No. The Act defines a qualified trustee to include an authorised person resident in Mauritius and uses trustee residence or business as a factor in determining a trust's closest connection, which is a governing-law question, not a tax rule.^[1]

What Mauritius trust tax return does the Trusts Act require?

The Trusts Act requires none. It provides for keeping and submitting trust accounts, which is an accounting duty. Any Mauritius tax return duty comes from Mauritius tax law.^[1]

When can Form 3520 apply to a U.S. person connected to a foreign trust?

The IRS lists transfers to a foreign trust, loans, distributions, and ownership under grantor trust rules among the events that can require Form 3520 reporting. The instructions require a separate form for transactions with each foreign trust.^[5]^[6]

What does Form 3520-A report?

Form 3520-A is the annual information return for a foreign trust with a U.S. owner. The IRS says the trust supplies required annual statements to U.S. owners and beneficiaries.^[5]

How does the IRS describe income reporting for a U.S. owner?

A U.S. person treated as owner under grantor trust rules is generally taxed on the trust's income. The foreign trust's owner statement includes information about income reported on the owner's U.S. income tax return.^[5]

What is the general Form 3520 deadline?

The instructions generally set the Form 3520 due date at the fifteenth day of the fourth month after the taxpayer's tax year ends. Qualifying individuals outside the United States have a due date in the sixth month if they meet the stated conditions and include a statement with the form.^[6]
