Cross-Border Tax
Foreign Non-Grantor Trust Tax, Explained.
A structured, jurisdiction-by-jurisdiction overview of how a foreign non-grantor trust is taxed and reported under United States, United Kingdom, Canadian, and Kenyan tax law, written from the corporate trustee's chair, and never a substitute for qualified tax counsel in each jurisdiction that touches your trust.
This is not tax advice. Cross-border trust taxation is fact-specific and changes frequently. This overview describes the general shape of the rules as a corporate trustee understands them for the purpose of administering trusts. Every trust structure must be reviewed by qualified tax counsel in the settlor's home jurisdiction, the governing jurisdiction of the trust, and every jurisdiction in which a beneficiary is resident.
Foundations
Three Concepts That Drive the Entire Analysis
Before any jurisdiction is discussed, three definitions must be settled. Most confusion about foreign trust tax collapses back to one of these three.
Grantor vs. Non-Grantor
A grantor trust is treated, for tax purposes, as if the settlor still owned its assets and income. A non-grantor trust is treated as a separate taxpayer. Whether a foreign trust is grantor or non-grantor depends on the settlor's home tax law, not the trust deed's label.
Foreign vs. Domestic
'Foreign' is a tax-residence classification. In US terms, a trust is foreign unless it satisfies both the court test (a US court can exercise primary supervision) and the control test (a US person controls all substantial decisions). Other jurisdictions apply their own residence rules, which frequently produce different answers on the same facts.
Distributable Net Income (DNI)
DNI is the mechanism that pushes tax character from the trust to the beneficiary in a non-grantor trust. Distributions in the current year carry out current-year income; distributions in excess of DNI are treated as distributions of accumulated income or of corpus, depending on the jurisdiction.
Jurisdiction · United States
United States: Non-Grantor Status and the Reporting Regime
For US persons, the foreign non-grantor trust is the classical vehicle for holding family capital outside the US grantor-trust net. Non-grantor status turns the trust into a separate US taxpayer, and pushes tax character to US beneficiaries through the DNI mechanism when income is actually distributed. The reporting regime, not the underlying tax, is where most US settlors and beneficiaries get into difficulty.
- ●The trust is a separate taxpayer for US federal income tax. The settlor is not taxed on trust income if none of IRC §§671–679 (including §679's rule for US-transferor foreign trusts with US beneficiaries) treats the settlor as the owner.
- ●The trust files Form 1040-NR only if it has US-source income or ECI; otherwise, US reporting flows through the US settlor, US owner, or US beneficiaries.
- ●US persons file IRS Form 3520 for transfers to, ownership of, or distributions from a foreign trust. The trust (or its US owner) files IRS Form 3520-A annually.
- ●US beneficiaries who receive distributions in excess of current-year DNI are subject to the throwback rules of IRC §§665–668, including an interest charge on accumulated income deemed distributed in earlier years.
- ●US beneficiaries with signature authority over trust accounts, or US persons with reportable specified foreign financial assets, may also have FBAR (FinCEN 114) and Form 8938 obligations.
- ●Distributions of trust corpus (as opposed to income) are generally not taxable to a US beneficiary, but the trust must maintain records that allow the character of each distribution to be substantiated.
Jurisdiction · United Kingdom
United Kingdom: Settlor-Interested Rules and the ToAA Regime
UK tax analysis does not map onto the US grantor / non-grantor split. The UK asks instead whether the settlor is interested in the trust, whether the trust is UK-resident, and whether income or gains are attributable to a UK person under the transfer of assets abroad legislation. UK-resident beneficiaries of a non-resident trust are generally taxed on distributions, not on undistributed income. The anti-avoidance regimes around accumulated income and capital payments are wide, and every distribution to a UK-resident beneficiary should be reviewed with UK counsel.
- ●The UK does not use the US grantor/non-grantor terminology. A UK-resident settlor who retains an interest in a non-UK trust is generally caught by the settlor-interested rules and the transfer of assets abroad (ToAA) legislation, which can attribute trust income to the settlor.
- ●For non-settlor-interested, non-UK-resident trusts, UK-resident beneficiaries are typically taxed on the receipt of income or capital, not on undistributed trust income. Subject to the offshore income gains and capital payments regimes for accumulated gains.
- ●Trustees of a non-UK-resident trust with UK-source income or UK real estate have their own UK tax and reporting obligations, and may fall within the Trust Registration Service (TRS) if the trust has UK tax exposure or acquires UK land.
- ●Non-UK-domiciled settlors and beneficiaries face specific rules on the remittance basis and, following recent UK reforms, the treatment of trusts settled before a change of long-term-residence status. Trustees should coordinate with UK counsel on every distribution to a UK-resident beneficiary.
Jurisdiction · Canada
Canada: Section 94 and the Deemed-Resident Trust
The dominant issue for Canadian families is section 94 of the Income Tax Act. Where the section applies, an offshore trust is treated as resident in Canada for tax, and much of the perceived benefit of the offshore structure is neutralised for Canadian tax purposes. Any Canadian contributor or Canadian beneficiary should assume section 94 is in scope until qualified Canadian tax counsel has cleared it, in writing, for the specific facts of the trust.
- ●Under section 94 of the Income Tax Act (Canada), a foreign trust with a Canadian-resident contributor or a Canadian-resident beneficiary can be treated as resident in Canada for tax purposes, sometimes referred to as the deemed-resident trust rules. This is the single most important issue in structuring for Canadian families.
- ●Where section 94 applies, the trust is taxed on its worldwide income as a Canadian resident, and Canadian contributors and beneficiaries are jointly and severally liable for the trust's Canadian tax, subject to statutory limits.
- ●Canadian-resident beneficiaries are also subject to reporting obligations, including Form T1142 (distributions from and indebtedness to a non-resident trust) and Form T1141 (information return in respect of contributions to non-resident trusts). Contributors may have Form T1141 obligations from the year of contribution forward.
- ●Even where section 94 does not apply, distributions of foreign accrual property income (FAPI) and distributions from non-resident trusts remain reportable and can be taxable in the beneficiary's hands.
Jurisdiction · Kenya
Kenya: Trusts as Separate Persons, Residence, and Disclosure
Kenya taxes trusts as separate persons under the Income Tax Act, with residence determining the scope of taxable income and beneficiaries taxed on distributions of trust income. For Kenyan-resident settlors and beneficiaries, an offshore structure does not displace Kenyan tax analysis. It sits alongside it, and Kenyan tax counsel should review the structure before settlement and each time the beneficiary class or distribution pattern changes.
- ●Under the Kenyan Income Tax Act, a trust is generally treated as a separate person for tax purposes. Income accruing to a Kenyan-resident trust is taxable in Kenya on a worldwide basis; a non-resident trust is taxable in Kenya only on Kenyan-source income.
- ●Distributions of trust income to Kenyan-resident beneficiaries are generally taxable in the beneficiary's hands, subject to any withholding at the trust level and to the double-tax treaty network Kenya has entered into.
- ●Trusts established under Kenyan law are subject to the licensing and supervisory framework applicable to trustees (including corporate trustees) and to Kenya's evolving beneficial-ownership disclosure and AML regime.
- ●Where a Kenyan-resident settlor establishes an offshore trust, the settlor's Kenyan tax position depends on residence, source, and the specific terms of the deed, and requires Kenyan tax counsel in every case. Offshore trusts are not a substitute for compliance with Kenyan tax law.

Trustee Coordination
What the Corporate Trustee Actually Does
A corporate trustee is not a tax adviser. What the trustee does is administer the trust so that its tax posture, in every jurisdiction that touches it, can be accurately reported. In practice, that means maintaining trust-level accounting to a standard that supports DNI computation for US purposes, capital payment tracking for UK purposes, section 94 exposure documentation for Canadian purposes, and residence-and-source analysis for Kenyan purposes.
The trustee's discipline is what makes the tax analysis possible. The tax analysis itself is done by qualified counsel in each jurisdiction, with whom the trustee coordinates on scheduled reporting, distribution reviews, and any structural change to the trust.
