The Swiss approach follows substantive rights and control rather than the label used in the trust instrument.

The trust itself is not treated as a separate corporate taxpayer; assets and income are generally attributed to the settlor or a beneficiary.
Powers retained by the settlor may cause revocable treatment and continuing attribution to the settlor.
An irrevocable fixed-interest trust turns on an enforceable beneficiary interest; for a discretionary trust, the settlor's residence at formation and actual distributions are central.
Contributed capital, income and capital gains must be evidenced separately; without proof, the whole payment to a beneficiary may be treated as taxable income.
01
Substance-based classification
The circular distinguishes revocable, irrevocable fixed-interest and irrevocable discretionary trusts. The central question is whether the settlor has definitively divested the assets. A right to revoke the trust, replace the trustee or protector, alter beneficiaries, demand termination or veto asset decisions points to retained control. A formal 'irrevocable' label therefore does not prevent revocable treatment.
02
Attribution of assets and income
Because a foreign trust lacks legal personality and is not equated with a foreign legal entity for these purposes, the trust itself is not taxed on its assets and income. Nor are they generally attributed to a trustee or protector, apart from fees for their services. A revocable trust remains attributable to the settlor. Under a fixed-interest trust, an identified share may be attributed to the beneficiary, including for wealth-tax purposes. For a discretionary trust, the circular connects the result to the settlor's residence at formation and to the emergence of an enforceable right or an actual payment.
03
Distributions, evidence and withholding taxes
A beneficiary payment is classified by its nature: income, repayment of contributed capital, private capital gain or gift. The result is fact-sensitive and cantonal rules remain relevant where inheritance or gift taxes arise. The circular separately addresses Swiss withholding-tax refunds and treaty relief; the existence of a trust does not itself create a refund entitlement. A defensible file should trace each payment, the parties' rights, residence and beneficial entitlement.
