DAC8 Is Live: 2026 Becomes the First EU Crypto Reporting Year

Executive Overview

The European Union's DAC8 rules apply from 1 January 2026 and extend automatic tax-information exchange to crypto-assets. Reporting Crypto-Asset Service Providers must collect information on reportable transactions involving EU-resident users during the 2026 reporting year, and the European Commission indicates that the first reporting cycle will take place in 2027, with exchanges between tax authorities following the reporting year.

For Switzerland the position needs to be stated precisely. Switzerland is not an EU Member State and DAC8 does not impose Swiss reporting obligations. It nevertheless affects Swiss businesses that operate within the European Union, and Swiss private clients who use EU-based platforms, because the data those platforms collect concerns the user's state of tax residence.

Regulatory Background

DAC8 is built on the OECD Crypto-Asset Reporting Framework and its scope is broad, covering a wide range of crypto-assets and of service-provider activity. The reporting obligation attaches to the provider rather than the user, but it is driven by information the user supplies, which places the accuracy of self-certification and residence data at the centre of the system.

A provider operating in the European Union without authorisation under MiCA may face single-registration requirements in order to discharge its DAC8 obligations. The interaction between the regulatory regime and the reporting regime is therefore relevant when assessing how a Swiss business serves EU clients, and it should be considered at a structural level rather than treated as a purely administrative formality.

Why It Matters

The first reporting year has already begun, which means the data being generated now is the data that will be exchanged. Corrections made later apply to a record that has already been reported.

• Swiss and other non-EU crypto-asset businesses serving EU-resident users, which may fall within the reporting regime through their EU activity.
• Reporting Crypto-Asset Service Providers established in the European Union, which must operate collection, due-diligence and reporting processes for the 2026 year.
• Swiss private clients using EU-based platforms, whose transactions will become more visible to their state of tax residence.
• International families and family offices with digital-asset exposure held across several jurisdictions and platforms.
• Entrepreneurs and companies accepting or settling in crypto-assets within the European Union, where transaction records feed both accounting and reporting.
• Financial intermediaries and advisers, who will need to explain the gap, where one exists, between platform data and declared positions.

Practical Issues to Review

1. 01Determine whether the business falls within the definition of a Reporting Crypto-Asset Service Provider by reason of its EU activity, and document the analysis.
2. 02Review authorisation status under MiCA and any resulting single-registration requirement associated with DAC8 obligations.
3. 03Verify that user self-certification captures tax residence and identification data accurately, and that the information is refreshed when circumstances change.
4. 04Reconcile wallet histories, exchange records and custody statements against declared tax positions, including transfers between accounts held by the same person.
5. 05Confirm that valuation methods and transaction classifications used for accounting purposes are consistent with those used for tax reporting.
6. 06Assess whether existing record-keeping will support the 2026 reporting year in 2027, allowing for platform changes during the intervening period.
7. 07For Swiss-resident users, review the completeness of declarations covering assets held on EU platforms, rather than assuming that visibility begins only at reporting.

TCC View

TCC's view is that 2026 is the year to reconcile wallet histories, exchange data and tax reporting. The operational gap between decentralised transactions and tax records will become harder to sustain as reporting frameworks mature, and the cost of closing that gap rises with every additional year of unreconciled activity.

We would also distinguish carefully between EU obligations and Swiss client impact. A Swiss business does not become subject to DAC8 because its clients are internationally mobile; it may become subject to it because of what it does within the European Union. Conversely, a Swiss individual has no DAC8 obligation at all, but should expect the platforms they use to report information relevant to their residence. Conflating the two leads either to unnecessary compliance work or to unwarranted comfort.

Planning Note

The reporting year is running and the first cycle falls in 2027, so preparation should be treated as current rather than future work. Businesses with EU activity should confirm their status, authorisation position and data-collection processes now, while individuals should complete the reconciliation of their holdings before the first exchanges occur. Developments to monitor include national implementation of DAC8 by individual Member States and the progress of comparable frameworks in Switzerland, which will determine how the two systems eventually interact.
