From 2026, new rules for cryptocurrencies will apply across the European Union. The background is the EU directive DAC8 (Directive on Administrative Cooperation 8), which significantly expands the exchange of information between tax authorities. The aim of the new provisions is to make transactions involving Bitcoin, Ethereum and other cryptoassets more transparent and to enable taxable gains to be tracked more effectively.
For investors, this means one thing above all: the crypto space is no longer a black box for tax offices. Exchanges, brokers and other providers will in future have to report data to authorities, and this information will be shared automatically within the EU.
This affects not only active traders, but in principle everyone who uses crypto service providers - whether privately or for business.
In recent years, the crypto market has grown rapidly. At the same time, tax authorities had a problem: unlike traditional bank accounts or securities portfolios, many transactions were difficult to trace.
While banks have long taken part in the automatic exchange of information, there were no comparable rules in the crypto sector for a long time. Profits still had to be taxed, but authorities often had to rely on users voluntarily providing correct information.
With DAC8, the EU wants to close this gap.
The directive requires crypto service providers to collect tax-relevant information and report it to national authorities. This data is then exchanged between EU member states.
This creates, for the first time, an EU-wide system that works in a similar way to the well-known data exchange for bank accounts.
The new rules apply to so-called crypto-asset service providers. These include, among others:
crypto exchanges
brokers for digital assets
custodians and custody providers
platforms for exchanging cryptocurrencies
providers that facilitate transfers or wallet services
What matters is not only where the company is based. Providers outside the EU may also be affected if they serve customers within the EU.
That means: if you are an EU taxpayer using a regulated platform, you should expect your data to be reported.
The reporting obligations go much further than many expect. Providers must not only transmit balances, but also detailed information about transactions.
Reported items include, among other things:
name, address and date of birth
tax residence
tax identification number
wallet or account numbers on the platform
buy and sell transactions
swap transactions between cryptocurrencies
deposits and withdrawals
total holdings at year end
number and value of transfers
This data is reported to the tax authority of the country in which the user is tax resident. Within the EU, the information is forwarded automatically.
This will allow authorities to see relatively precisely who is actively trading cryptocurrencies and at what scale.
So that providers can meet their reporting obligations, users must provide additional information. This primarily includes tax residence.
In practice, this means platforms will in future request information such as:
country of residence
tax ID
other tax residences
personal identification details
Without this information, providers cannot fulfil their legal duties. Therefore, they are entitled to restrict accounts if users do not provide the required details.
Many platforms have already announced that trading or withdrawals may be blocked if the necessary data is not available.
The new rules affect not only providers, but also users. Anyone who provides incorrect information or fails to submit their data in good time can run into difficulties.
In many EU countries, fines may be imposed if:
self-certifications are not submitted
incorrect tax data is provided
information is intentionally incomplete
In addition, users risk having their account restricted until all information is provided.
The rules are also strict for the providers themselves. If they do not report data or transmit it inaccurately, they may likewise face penalties.
That is why many platforms now scrutinise their customers far more closely than they used to.
An important point:
DAC8 does not introduce any new taxes.
The directive mainly concerns the exchange of information. How cryptocurrencies are taxed continues to depend on the relevant national tax law.
In many European countries, the general position is:
profits from short-term trading may be taxable
long-term holding may be treated differently for tax purposes
staking, lending or mining may be treated as income
different rules apply to business assets than to private holdings
What changes with DAC8 is not the tax itself, but the likelihood that incorrect declarations will be detected.
A key element of the new rules is the automatic exchange between states.
When a platform reports data, it is first sent to the tax authority in the platform’s country of establishment. From there, it is forwarded to the country in which the user is tax resident.
This means, for example:
you live in Spain but use an exchange in Germany
or you are tax resident in Italy and trade via a platform in Estonia
In both cases, the data can be passed on to the competent tax authority.
The exchange works similarly to the well-known CRS system for bank accounts.
Many people wonder whether anonymous trading will still be possible with DAC8.
Within regulated platforms, it will become significantly more difficult. Most major exchanges will in future have to report data.
Pure self-custody wallets are not currently affected, provided they are not used via a reportable service provider. Decentralised platforms do not always fall under the same rules either.
Even so, this does not mean profits are automatically tax-free. In most countries, there remains an obligation to declare income yourself.
In addition, the legal framework may continue to change in the future.
The rationale behind the new rules is clear. Estimates suggest that billions are moved with cryptocurrencies in Europe every year.
Without reporting obligations, it was difficult for authorities to verify whether these gains were taxed correctly.
DAC8 creates, for the first time, a data basis that makes it possible to analyse transactions systematically. Cases will stand out in particular where high turnover occurs but very little profit is declared.
Older periods may also come under greater scrutiny as a result.
For investors, this mainly means that proper documentation becomes more important.
It is no longer enough simply to file a tax return. Anyone carrying out many transactions should be able to show:
when coins were bought
at what price
when they were sold
what fees were incurred
which wallets were used
Without such records, it can become difficult to answer questions from the tax authority.
With DAC8, the crypto space is being regulated more heavily than before. Exchanges and other providers must report extensive data, and this information will be exchanged automatically within the EU.
For investors, this does not automatically mean higher taxes, but it does mean substantially more transparency.
If you document your transactions correctly and meet your tax obligations, you generally have nothing to worry about. If, on the other hand, you assume crypto profits will remain invisible, you should review your position now.
In any case, the days when the crypto market was barely traceable for tax authorities are over.
