Swiss Crypto Reporting: CARF Implementation Delayed to 2027 at the Earliest

Executive Overview

Switzerland has approved the domestic and international legal framework for the OECD Crypto-Asset Reporting Framework, but implementation has been delayed. The State Secretariat for International Finance confirms that CARF cannot be implemented before 1 January 2027 at the earliest, because parliamentary deliberations on the partner states with which information would be exchanged are still ongoing.

The immediate practical consequence is that Swiss CARF due-diligence, reporting and registration duties do not apply in 2026, and Switzerland will not receive crypto-asset data from abroad for the 2026 calendar year under CARF. The longer-term consequence is unchanged: the framework has been adopted, and the delay concerns activation rather than direction.

Regulatory Background

CARF is the OECD standard for the automatic exchange of information on crypto-assets, built on due diligence performed by reporting crypto-asset service providers and on self-certification by their users. Switzerland has put the legal basis in place, but exchange under such a framework requires activation with specific partner states, and that step remains before Parliament.

Providers may nevertheless adapt self-certification and data-collection processes voluntarily in preparation for future implementation. This is not merely a matter of goodwill: the information the framework requires is historical in nature, and a provider that begins collecting it only when the obligation crystallises will be reconstructing records rather than maintaining them.

Why It Matters

A postponement of legal application is not a postponement of practical preparation. The data that CARF will require is difficult to remediate retrospectively, and the difficulty grows with the volume and age of the transaction history involved.

• Swiss crypto-asset service providers, which will need registration, due-diligence and reporting capability once the framework is activated.
• Financial intermediaries offering crypto-related services alongside traditional products, where classification of the activity determines which regime applies.
• Private clients holding crypto-assets across multiple wallets and platforms, whose tax-residence position and transaction history will eventually need to reconcile.
• International families and family offices with digital-asset allocations held through companies, trusts or foundations, where entity classification is not always obvious.
• Entrepreneurs whose businesses receive, hold or settle in crypto-assets, and whose accounting records must support the tax treatment adopted.
• Advisers and auditors, who will be asked to substantiate the completeness of transaction data supporting a declared position.

Practical Issues to Review

1. 01Confirm that no Swiss CARF due-diligence, reporting or registration duty applies for 2026, and document the basis for that conclusion in internal compliance records.
2. 02Review onboarding and self-certification processes so that tax residence and identification data are captured in a form the framework will accept.
3. 03Assess entity classification for holdings held through companies, trusts or foundations, and determine who would be treated as the relevant person.
4. 04Test the completeness and integrity of transaction history across wallets, exchanges and custodians, including transfers between accounts controlled by the same person.
5. 05Reconcile crypto positions and realised results with declared tax positions in the relevant state of residence, and document valuation methods used.
6. 06Establish record-retention practices that survive a change of platform, custodian or provider, since data is frequently lost at the point of migration.
7. 07Define internal ownership of CARF readiness, with a timeline that anticipates activation rather than reacting to it.

TCC View

TCC's view is that the delay should be used as an implementation window. Providers can build controls, self-certification processes and data architecture before mandatory reporting begins, at a pace and cost that will not be available once a deadline is fixed. Preparation performed voluntarily is materially cheaper than preparation performed under obligation.

For investors and private clients, the appropriate assumption is that cross-border crypto transparency will continue to increase, in Switzerland and elsewhere. The relevant planning question is therefore not whether holdings will become visible, but whether the documentation supporting their treatment is complete and consistent when they do. Reconstructing a fragmented transaction history several years after the event is the outcome to avoid.

Planning Note

Implementation cannot begin before 1 January 2027 at the earliest, and the timing depends on the outcome of parliamentary deliberations on partner states. That outcome should be monitored rather than predicted, and no position should assume either an earlier or a later start than the legislative process delivers. In the meantime, the preparatory work is unaffected by the timetable: data quality, classification and documentation are worth completing regardless of when the obligation takes effect.
