26.6 Foreign Trusts, Grantor Control & Abusive Schemes
Key Takeaways
Irrevocable status under state law does not by itself make a trust a non-grantor trust for federal income tax.
A domestic trust must satisfy both the U.S. court test and the U.S.-person control test.
Assigning earned income or personal expenses to a trust does not create a lawful deduction or remove the earner’s tax liability.
Classify ownership before computing distributions
A trust can be valid under state law while its income remains taxable to the grantor under federal tax rules. Grantor-trust provisions in §§671–679 examine retained powers, benefits, reversionary interests, and other statutory conditions. Revocability is a strong indication, but an irrevocable trust can also be wholly or partly a grantor trust. Do not use the word irrevocable as a substitute for reviewing the governing document and actual powers.
If the grantor is treated as owner of a portion, the attributable income, deductions, and credits generally are reported by that owner under the applicable reporting method. A non-grantor trust instead generally computes its own taxable income and any income distribution deduction. A trust can have both grantor and non-grantor portions, requiring separate tracking rather than assigning every dollar to one treatment.
Domestic or foreign trust
A trust is domestic only if both the court test and control test are met. A U.S. court must be able to exercise primary supervision over administration, and one or more U.S. persons must have authority to control all substantial decisions. Failing either test generally makes the trust foreign for federal tax purposes. The trustee's postal address, the location of one bank account, or the place a document was signed does not decide the issue alone.
Substantial decisions can include distributions, beneficiary selection, investment decisions, termination, and replacing trustees, according to the governing rules. A foreign person's veto over a substantial decision can matter even if most trustees are U.S. persons. Distinguish the authority to decide from routine administrative work performed by an agent.
Example: A U.S. court can supervise a trust, but a foreign protector must approve every distribution and cannot be removed by U.S. persons. The court test alone does not establish domestic status. Analyze whether U.S. persons control all substantial decisions before reporting the arrangement as a domestic trust. Conversely, owning foreign securities does not automatically make an otherwise domestic trust foreign.
International reporting and ownership
U.S. persons can have Form 3520 obligations for specified transfers to foreign trusts, ownership, distributions, and certain foreign gifts. A foreign trust with a U.S. owner generally has Form 3520-A annual information-reporting duties, with the U.S. owner responsible for ensuring the required information is supplied. The forms have different filers and deadlines. Filing one does not automatically satisfy the other.
Form 3520-A generally is due by the fifteenth day of the third month following the foreign trust's tax-year end, with an extension requested through the applicable Form 7004 procedure. Form 3520 generally follows the U.S. person's applicable income-return timing and extension rules but is filed according to its own instructions. A substitute Form 3520-A may be required when the foreign trust fails to file. Do not assume an extension of an owner's Form 1040 automatically extends the foreign trust's separate Form 3520-A.
Penalties can apply even if the underlying income was reported and no additional income tax is due. A foreign account can separately create FBAR or Form 8938 reporting, depending on the filer and facts. Keep trust ownership, transactions, and financial-account reporting on distinct lines of the compliance checklist.
Recognize an abusive trust arrangement
Promoters may describe a trust as eliminating self-employment tax, allowing deductions for all household costs, or making income invisible by passing it through multiple domestic or offshore trusts. Federal taxation follows substantive ownership and earning activity, not the number of layers or the name on an invoice. An individual who earns service income generally cannot avoid tax merely by directing the customer to pay a trust.
A trust's payment of groceries, school fees, or the grantor's vacation does not create a business deduction. It may be a payment for the owner's benefit, a distribution, or another taxable transfer depending on the facts. The ordinary and necessary business-expense rules still require a real business connection. A trustee's compensation and administration costs require their own substantiation and allocation rather than a blanket percentage of gross income.
| Promoter claim | Required tax analysis |
|---|---|
| All personal expenses become deductible | Apply §262 and actual business or fiduciary deduction rules |
| Offshore trusts need no U.S. reporting | Apply grantor, foreign-trust, and information-reporting rules |
| Assigning wages makes them trust income | Apply assignment-of-income principles |
| A charity label shelters distributions | Verify a genuine qualified charity and actual charitable transfer |
A lawful trust can serve estate planning, asset management, or beneficiary protection without promising impossible tax results. Tax shelter terminology does not itself decide legality; examine the actual transaction and authority. A beneficiary's legitimate DNI inclusion, a grantor's ownership inclusion, and fraudulent omission of income are different outcomes.
For preparation questions, identify the owner, residence classification, source and character of income, and recipient of benefits. Then select the return or information form. Never start by assuming that a trust name means either tax exemption or tax evasion.
