Two major EU regulatory milestones are colliding in 2026. MiCA (Markets in Crypto-Assets Regulation) reaches full enforcement on July 1, 2026, forcing every crypto exchange serving EU users to obtain a CASP licence. And DAC8 — Council Directive 2023/2226 — entered into force on January 1, 2026, requiring those same licensed exchanges to automatically report their users' transaction data to national tax authorities across the EU.

Together, these two directives mark the end of the "grey zone" era for crypto in Europe. If you hold crypto on any major exchange and you are an EU resident, your transaction history is now — or will very soon be — visible to your country's tax authority. This guide explains what DAC8 is, what data is shared, who it affects, and what practical steps you should take.

What is DAC8?

DAC8 is the informal name for Council Directive 2023/2226, which amends the EU's Directive on Administrative Cooperation (DAC). It extends an existing framework — already used for bank account reporting and dividend income — to cover crypto-asset transactions.

In practical terms: exchanges and brokers that are authorised as Crypto-Asset Service Providers (CASPs) under MiCA are now required to collect detailed transaction data for all EU-resident users, and submit annual reports to the national tax authority in their country of licensing. Those national authorities then automatically share the data with the tax authority in the user's country of residence.

This is the same infrastructure used to share bank data across the EU under CRS (Common Reporting Standard) — just extended to crypto. The first reporting period covers tax year 2026; the first cross-border exchange of information between EU tax authorities happens in 2027.

In short: DAC8 = automatic crypto transaction reporting, EU-wide, starting with tax year 2026. Your exchange reports to the tax authority. You are not exempt from declaring.

What Data Gets Reported?

DAC8 mandates collection and reporting of the following information for every EU-resident account holder:

Data Category What is Shared
User Identity Full name, address, date of birth, Tax Identification Number (TIN), country of residence
Account Balances Crypto holdings at year-end, per asset (BTC, ETH, etc.)
Sales & Exchanges Proceeds from crypto-to-fiat sales AND crypto-to-crypto swaps
Transfers Crypto sent to or received from external wallets or other exchanges
NFT Sales Proceeds from NFT sales where the CASP facilitates the transaction

Note that DAC8 captures proceeds and transfers, not necessarily the gain/loss calculation — that remains your responsibility when filing your tax return. The data reported gives tax authorities enough to cross-check your declarations.

Which Exchanges Are Affected?

DAC8 applies to all entities classified as Crypto-Asset Service Providers (CASPs) under MiCA that serve EU-resident users. This includes:

From July 1, 2026, operating in the EU without a CASP licence is illegal. This means the universe of DAC8-obligated entities is essentially identical to the universe of legal exchanges for EU users. An exchange without a MiCA licence after July 1 would have to block EU users — making DAC8 compliance moot for them, but also making them inaccessible to you.

If you currently use an exchange that has not yet obtained its MiCA licence, now is the time to review your options. See our guide: Which Exchanges Are at Risk After July 2026? and MiCA Deadline July 1, 2026: What Changes for EU Investors.

What About Self-Custody Wallets?

DAC8 does not apply to non-custodial wallets. If you hold crypto in a hardware wallet (Ledger, Trezor) or a self-custody software wallet (MetaMask in self-custody mode), that wallet is not a CASP and is not covered by DAC8 reporting obligations.

However, there are two important nuances:

Self-custody is a valid and legal choice for EU investors. But it does not make your crypto invisible to tax authorities if those assets originally came from a reported exchange account.

What Does This Mean for You as an Investor?

DAC8 changes the information landscape — not your tax obligations. Here is what changes and what does not:

What Does NOT Change

  • Your obligation to declare crypto income
  • Tax rates — these are set by each member state
  • Self-custody wallet rules
  • The fact that you must file your own return

What DOES Change

  • Tax authorities now receive exchange-reported data automatically
  • Cross-border enforcement becomes much easier
  • Underreporting is now detectable and cross-checkable
  • KYC data is linked to transaction history in reporting

Practical recommendations for every EU crypto investor:

"Nothing to hide, nothing to fear." For the vast majority of crypto investors who declare their gains honestly, DAC8 is a non-event. It is simply a new piece of EU infrastructure that increases transparency — the same way bank interest reporting has worked for decades.

Key Dates at a Glance

Date Event Impact
1 Jan 2026 DAC8 enters into force CASPs begin collecting reportable transaction data
1 Jul 2026 MiCA full enforcement All EU exchanges must hold CASP licence or exit EU market
Early 2027 First DAC8 reports submitted CASPs submit 2026 tax year data to national tax authorities
2027 First EU cross-border data exchange Tax authorities share data across member states automatically
2028+ Full regime in effect Annual cycle: report → exchange → enforcement

DAC8 and MiCA: How They Connect

DAC8 and MiCA are separate legal instruments but they are designed to work together. MiCA creates the licensing regime: it defines what a CASP is, what obligations it must meet (capital requirements, custody rules, consumer protection), and which EU regulator supervises it.

DAC8 then uses MiCA's definition of "CASP" as the trigger for tax reporting obligations. In other words: MiCA creates the regulated class of entities; DAC8 requires those entities to report their users' transactions.

This is why the MiCA deadline of July 1, 2026 matters so much for tax transparency. Once every operating EU exchange holds a CASP licence, DAC8 reporting has universal reach. There is no longer a legal route to serve EU users without also reporting their transaction data.

Frequently Asked Questions

Does DAC8 apply to Bitcoin on Coinbase, Binance, or Kraken?

Yes. If you are an EU resident and the exchange holds a MiCA/CASP licence — which Coinbase, Binance, and Kraken all do in 2026 — then DAC8 applies. Your account balances, proceeds from sales, and transfers will be reported annually to your national tax authority.

Will I get taxed automatically under DAC8?

No. DAC8 is a reporting directive, not an automatic tax. Your exchange sends transaction data to tax authorities. You are still responsible for filing your own tax return accurately. DAC8 makes it much easier for authorities to detect underreporting — it does not do the declaration for you.

Does DAC8 apply to self-custody wallets like Ledger or Trezor?

No. DAC8 applies exclusively to CASPs — entities that hold your crypto assets. Non-custodial hardware wallets (Ledger, Trezor) and self-custody software wallets (MetaMask in non-custodial mode) are not in scope. Note, however, that transfers from an exchange to a self-custody wallet are still visible in the exchange's DAC8 report.

What if my exchange does not have a MiCA licence?

After July 1, 2026, exchanges operating in the EU without a valid MiCA CASP licence are illegal. They must block EU users. If you are currently using such an exchange, you need to migrate your assets to a licensed platform before that date. See: Exchanges at Risk After MiCA 2026.

Is DAC8 the same as MiCA?

No. MiCA is the business regulatory framework for crypto companies in the EU — licences, conduct rules, consumer protection. DAC8 is the tax directive requiring those companies to report user transaction data. They are complementary: MiCA defines the regulated entities; DAC8 requires them to report. Different laws, different purpose, designed to work together.
