January 1, 2026, marks the entry into force of the new European directive DAC8, which extends tax cooperation to digital assets. It requires cryptocurrency exchange platforms to report information to tax authorities. Should this be seen as a revolution for crypto-asset investors, or simply a logical evolution?
In practice, DAC8 primarily aims to fill a legal vacuum and align cryptocurrency taxation with existing financial standards. For prudent savers accustomed to traditional investments, there is no reason to fear a drastic upheaval, it is rather a harmonization that brings clarity and transparency.
DAC8, which stands for "Directive on Administrative Cooperation 8," is the eighth revision of the EU directive on administrative cooperation in the field of taxation. It is directly inspired by the model applied to banks since 2016. Indeed, Europe already automatically exchanges information on bank accounts and other financial investments between tax administrations via the international CRS (Common Reporting Standard).
DAC8 integrates cryptocurrencies into this existing information exchange mechanism between Member States to combat tax evasion related to these new assets.
Concretely, DAC8 imposes several key obligations on crypto exchange platforms, known as CASPs (Crypto-Asset Service Providers) at the European level, some of which have already been in place for a long time:
Active since January 1, 2026, the first reports will cover transactions made during the year 2026 and will be transmitted in 2027.
The spirit of the law is to provide a global view of movements, ensuring that income derived from crypto-assets is known to tax authorities even when the exchange occurs via a foreign platform or between individuals. It is worth noting that even platforms based outside of Europe must comply with DAC8 if they target users within the EU. Failure to do so may result in losing access to the European market or facing penalties.
In other words, this is an international cooperation measure: each EU country will adapt its legislation to require platforms to comply with this reporting starting in 2026. This data will circulate between administrations, ensuring that gains made via crypto-assets no longer fly under the radar.
DAC8 only concerns capital gains realized on exchanges and income (interest, staking) derived from crypto-assets. Contrary to some concerns, it does not target the mere holding of assets.
If you hold your crypto-assets without selling them, no new obligations apply to you (though you should still check if you need to declare a foreign account). However, if you sell for a profit, these gains must be declared and taxed according to your country’s tax laws.
You will simply be asked to provide your Tax Identification Number (TIN). This information ensures your transactions are correctly linked to your tax residency, as is already the case with traditional bank accounts. Find my TIN.
Furthermore, it’s worth remembering that French legislation has required the disclosure of foreign crypto platform accounts via Form 3916 since 2019, regardless of DAC8. This obligation remains in effect. DAC8 completes the system: whereas previously you declared your crypto gains on your honor, tax authorities will now be able to cross-check your filings with data provided by platforms.
Should you be worried? No. DAC8 does not change existing best practices. Tax authorities will receive information from platforms solely to verify consistency with your tax returns. In the event of a significant discrepancy, they may contact you, exactly as they would if your bank reported undeclared financial income. The principle remains that "information is exchanged between tax authorities for tax compliance purposes only." For those already declaring their gains, this change is negligible. For others, it is the ideal opportunity to regularize their situation.
Beyond taxation, DAC8 is part of a broader movement to normalize the cryptocurrency sector. The European Union has introduced multiple frameworks to oversee this emerging world: the MiCA regulation (2023) on crypto services (licensing, stablecoin reserves, investor protection), the Travel Rule/TFR for transfer traceability, and the DSA (Digital Services Act) for online content. The keyword here is to clean up and legitimize the crypto market, making it safer and more accessible to the general public.
Seeing cryptocurrencies adopt clear, supervised rules is often perceived as a reassuring sign of maturity by traditional finance players. Less opacity means fewer hidden risks. Moving forward, all compliant crypto exchanges must maintain clear transaction logs and remain accountable to authorities, just like a bank or a stockbroker. Regulation helps separate the "good actors" from the bad, protecting savers from unpleasant surprises.
By strengthening oversight, the EU seeks to avoid the kind of scandals that have shaken public trust, thereby fostering general adoption. For an individual or a company, investing through a regulated intermediary offers incomparable peace of mind: "you know where your money goes, who is holding it, and under which rules." This is exactly what encourages traditional investors to take the plunge into digital assets.
Many questions surrounding DAC8 concern the protection of personal data. By requiring service providers to transmit detailed transaction information, the directive raises a legitimate question: what data is shared, with whom, and in what context?
Regulated Exchanges for Strictly Tax PurposesIt is important to emphasize that DAC8 does not intend to make this data public or expose it outside the tax domain. The entire system relies on robust safeguards:
To be clear, this is not a public registry or a database accessible to third parties. It is inter-administrative cooperation, comparable to what already exists for traditional bank accounts.
At Paymium, we ensure that this new transparency is exercised in a secure environment that respects your rights. By choosing a regulated and historically reliable partner, you benefit from treatment that complies with the law, without compromising the security of your data.
The DAC8 directive represents a sober but structural turning point. Far from questioning the crypto model, it marks its entry into common law. By aligning crypto-assets with the standards already applied to bank accounts and traditional investments, the European Union is pursuing a clear goal: tax transparency, legal certainty, and investor confidence.
For those already correctly reporting their operations, this directive changes nothing in practice. For others, it ends a gray area and provides an opportunity to move forward on a healthy footing.
DAC8 contributes to the maturation of the sector. It bolsters the credibility of crypto-assets with the general public and prudent investors, while protecting users through a strict framework reserved exclusively for tax use. In this context, choosing a regulated and transparent actor like Paymium becomes, more than ever, an essential criterion.
Ultimately, DAC8 illustrates a fundamental trend: crypto is not disappearing under the weight of regulation; it is establishing itself permanently as an asset class in its own right. For the responsible, informed investor, this evolution is less a source of concern than a signal of market stability and maturity.
