Trust Reporting Requirements Compared: Registers, CRS and FATCA

Trust reporting requirements are not one regime but three layers that answer different questions: who stands behind the structure (registers and know-your-client files), where its holders are tax resident (CRS), and whether a US connection exists (FATCA). The same trust can be treated differently under each layer, and the treatment changes with the seat. This page compares the layers and describes how a regulated trustee reviews them every year.

Why the seat changes what a trust reports

A trust has no legal personality of its own in Switzerland. The trustee holds the assets in a fiduciary capacity, and the federal tax guidance says expressly that a trust is not a foreign legal entity within the meaning of the direct federal tax act. That starting point shapes everything that follows: reporting attaches to people and to the financial institution holding the account, not to the trust as a corporate body.

Other seats start from different premises. A common-law seat treats the trust as a core institution with its own case law and, often, its own statutory disclosure rules. A civil-law seat relies on recognition under the Hague Trusts Convention and on general anti-money-laundering rules. Which of these applies to your structure depends on the seat, the governing law and the residence of the people involved; that is a question for an individual analysis, not a general answer.

The three layers of reporting

Layer one: registers and identification

Under Article 4 of the Anti-Money Laundering Act (AMLA), a Swiss financial intermediary must identify the beneficial owner with the required diligence and verify that person's identity. A written declaration is required where the contracting party is not the beneficial owner, or where there is doubt. Article 7 requires records to be established and kept, and Article 8 requires organizational measures.

For a trust, this means the settlor, the beneficiaries, any protector and anyone holding effective control are identified and documented. Separately, a federal law on the transparency of legal entities and the identification of beneficial owners was finally adopted on 26 September 2025. The transparency register, kept by the Federal Office of Justice, started on 1 October 2026, with a reporting period that varies from one month to two years depending on the entity, and a supervisory authority within the Federal Department of Finance checks the data. The official announcement refers to legal entities, not to trusts, so whether and how a given trust is captured must be confirmed case by case. More on what is disclosed where is in our guide to trust registers and privacy.

Layer two: CRS classification

The Common Reporting Standard, or automatic exchange of information (AEOI), has been adopted by more than 100 states, including all major financial centers, according to the State Secretariat for International Finance. Its list of partner states was last updated on 8 October 2026, with Curaçao, Romania and Trinidad and Tobago among the most recent reciprocal additions.

A trust is classified for CRS purposes in one of two broad ways. If it is an investment-type entity managed by a financial institution, it may itself be treated as a financial institution and report. If not, it is usually a passive non-financial entity, and the account-holding bank looks through to the controlling persons, which for a trust include the settlor, trustees, protector, beneficiaries and anyone with ultimate control. The classification drives who files, which persons are named and which countries receive the report.

Layer three: FATCA status

The current Swiss FATCA regime rests on the agreement of 14 February 2013, with aggregated reporting and group requests. A Model 1 agreement, providing automatic and reciprocal exchange, was signed on 27 June 2024; according to the Federal Tax Administration its entry into force is planned no earlier than 1 January 2029, and implementation is under way. Until then, the status of each trust and each US-connected individual has to be read against the regime in force, and our page on a US person settlor explains why the seat choice is constrained there.

Reporting obligations by seat

The matrix below is a qualitative map. It shows the shape of each layer, not a legal opinion for a specific structure.

Two practical points follow. First, the CRS class is largely seat-independent in principle but depends on how the trustee and the assets are organized in practice. Second, the party that files is often the bank or the trustee, not the family, which is why consistency between the trustee file and the bank file matters. See also how regulated and lightly regulated seats differ in supervision.

How the Swiss tax guidance links to reporting

Reporting does not decide tax, but the data reported feeds tax assessment. The Swiss Tax Conference published circular 30 on the taxation of trusts on 22 August 2007, and the Federal Tax Administration's circular of 27 March 2008 applies it to direct federal tax and withholding tax. In short, the treatment depends on the type of trust:

• A revocable trust is transparent, so assets and income stay with the settlor at the settlor's domicile.
• An irrevocable fixed interest trust attributes assets and income to the beneficiary, who may be treated like a usufructuary.
• An irrevocable discretionary trust stays attributed to the settlor if the settlor was domiciled in Switzerland at creation, and is attributed to neither settlor nor beneficiary if the settlor was then domiciled abroad.

A report that names the wrong person as controlling person can therefore sit badly beside the tax treatment. Nothing here promises a particular tax outcome; it explains why the two must be read together.

The annual reporting review

The compliance and reporting service covers the know-your-client file, the beneficial owner records and the automatic exchange reports a trust must file. In practice the review follows a sequence.

1. Identify the settlor, beneficiaries and controlling persons, and compare the list with the trust deed and any letter of wishes.
2. Assess risk of the relationship, including residence, source of assets and links to sanctioned or high-risk places (see sanctions and reputation risk).
3. Screen parties and the origin of assets against the sources the trustee and bank are required to use.
4. Classify the trust for information exchange and confirm the filings that follow.
5. Monitor unusual activity, and record what was decided and why.

The review then feeds the calendar described in the annual compliance calendar by seat. For how the trustee's day-to-day duties differ by regime, see trust administration under different regimes.

What this service does not cover

It does not give tax advice, does not prepare personal tax returns and does not decide which seat is best. Fees depend on the structure and are indicated after the confidential assessment. Selecting or replacing a trustee is a separate subject.

What the confidential assessment establishes

The assessment sets out which registers and exchange regimes plausibly apply to your structure, which persons are controlling persons, where the trustee file and the bank file diverge, and which items need a specialist opinion in another country. It also shows what documents to gather: the trust deed, amendments, identity documents for each party and evidence of the origin of assets. See Switzerland as a trust seat for the wider context.
