From 1 January 2026, EU tax-transparency rules began covering a broad range of crypto-asset transactions. DAC8 does not create one EU crypto tax rate. It creates due-diligence, reporting, and automatic information-exchange obligations so national tax authorities can apply their existing tax laws with more data.
Quick answer: reporting crypto-asset service providers must collect information on reportable transactions involving EU-resident users during 2026. The first reporting and exchanges relating to that year take place in 2027, with the EU-level deadline window running through 30 September 2027. Users should keep complete records rather than wait for a platform statement.
Information date: 31 July 2026. National filing formats, tax rates, and implementation details differ; verify your country’s current rules.
What is DAC8?
DAC8 is the eighth amendment to the EU Directive on Administrative Cooperation in Direct Taxation. It extends automatic exchange of information between EU tax authorities to crypto-assets and is aligned in important respects with the OECD Crypto-Asset Reporting Framework (CARF).
EU member states were required to transpose the directive by the end of 2026 and apply its crypto-reporting provisions from 1 January 2026. The framework covers domestic as well as cross-border transactions so that users are not treated differently merely because their provider and tax residence are in the same member state.
Who reports under DAC8?
The rules apply to Reporting Crypto-Asset Service Providers (RCASPs), a term that includes entities and, in relevant cases, individuals that provide services effectuating exchange transactions in reportable crypto-assets for or on behalf of users.
The scope includes MiCA-authorized crypto-asset service providers and can also reach operators outside that authorization category. The European Commission notes that a provider operating in the EU without MiCA authorization may need single registration in a member state for DAC8 reporting.
Whether a particular wallet, protocol interface, marketplace, broker, or operator is an RCASP depends on the facts and legal definitions. “Decentralized” in a product name is not a complete legal analysis.
Which crypto-assets are covered?
DAC8 uses a broad scope linked to MiCA definitions and the international CARF approach. The European Commission states that it includes:
- crypto-assets issued in a decentralized manner;
- stablecoins, including e-money tokens; and
- certain NFTs that can be used for payment or investment purposes.
Not every token or NFT is automatically reportable. Providers must consider the legal criteria and exemptions, including the asset’s use. Users should not assume that labelling an asset “utility” or “collectible” puts it outside scope.
What transaction information is reported?
RCASPs must perform user due diligence and report identification and transaction information. According to the European Commission’s summary, data is subdivided by reportable crypto-asset and includes quantitative information such as aggregate gross amounts paid or received for:
- acquisitions and disposals against fiat currency;
- acquisitions and disposals against other reportable crypto-assets; and
- transfers, using aggregate fair market value where required.
The provider reports to its national tax authority. Information relating to users resident in other EU countries is then automatically exchanged with the tax authority of the user’s residence.
The 2026–2027 timeline
| Date | What happens |
|---|---|
| 1 January 2026 | DAC8 crypto reporting period begins; providers start collecting reportable user and transaction data |
| During 2026 | Providers conduct due diligence and users may receive tax-residence or self-certification requests |
| 2027 | Providers report 2026 data to national tax authorities under domestic procedures |
| By 30 September 2027 | First EU exchanges relating to the 2026 reporting year are due |
Providers report 2026 data to their national tax authorities during 2027 under the deadlines and formats set by domestic law. Separately, the first automatic exchanges between EU tax authorities are due by 30 September 2027, so a member state may require provider submissions well before that date.
What DAC8 does not do
It does not create a single EU crypto tax
Income, capital-gains, business, wealth, and VAT treatment remain matters of applicable tax law. DAC8 supplies information; it does not decide your tax rate or whether a specific transfer is taxable.
It does not mean every transfer is income
Moving assets between wallets you control may be non-taxable under some national rules, but the transfer can still appear in reported data. Keep address-ownership and transaction-fee evidence so you can explain it.
It does not make self-custody anonymous
A direct wallet-to-wallet transfer without a reporting intermediary is not the same as a transaction executed through an RCASP. However, deposits, withdrawals, purchases, or sales involving a provider can connect identity with blockchain addresses and values. Independent tax obligations still apply even when no provider reports a transaction.
It does not guarantee a complete tax return
Platform reports may use aggregates and may not know your original cost basis, transfers across other venues, DeFi activity, lost keys, gifts, or business context. The taxpayer remains responsible for the accuracy of local filings.
Why an exchange may ask for more information
Users may be asked to confirm tax residence, tax identification number, legal name, address, date of birth, or entity details. A legitimate request should occur through the provider’s authenticated site or app and explain its legal basis.
Do not send documents in response to an unsolicited email link. Open the platform independently, check the official support notice, and verify the domain. Tax-reporting season creates an opportunity for identity theft and phishing.
A record-keeping checklist for crypto users
- Confirm tax residence. Multiple homes, relocation, or cross-border work can require professional analysis.
- Export platform history regularly. Save trades, deposits, withdrawals, fees, staking, rewards, and fiat transactions before accounts close or formats change.
- Record self-custody addresses. Document which wallets you controlled and during what period.
- Preserve transaction hashes. A hash helps reconcile timestamps, assets, addresses, and network fees.
- Track cost basis in local currency. Record the valuation source and method required by your jurisdiction.
- Separate transfers from disposals. A withdrawal to your own wallet is economically different from a sale, even if both move assets.
- Reconcile provider reports. Compare any DAC8 statement with your ledger and request corrections through documented channels.
- Keep supporting context. Save evidence for gifts, donations, lost access, business inventory, mining, airdrops, and protocol failures.
DAC8, CARF, and MiCA
These frameworks have different purposes:
- DAC8 governs EU tax information collection and exchange.
- CARF is the OECD international crypto-asset reporting standard that informs cross-border implementation.
- MiCA regulates covered crypto-asset markets, issuers, and service providers in the EU.
A platform may have obligations under more than one framework. To verify its market authorization separately, use our guide to checking a MiCA-authorized crypto exchange.
Frequently asked questions
Will my 2026 crypto activity be reported in 2026?
Providers collect data during 2026. Reporting and automatic exchanges relating to that first year occur in 2027 under the applicable deadlines.
Does DAC8 cover stablecoins?
Yes. The European Commission expressly includes stablecoins, including e-money tokens, within the broad scope.
Are all NFTs reportable?
No. Certain NFTs can be covered when they meet the relevant payment or investment criteria. Classification is case-specific.
Do I need to report if an exchange does?
Provider reporting does not replace the taxpayer’s local filing obligations. Your return may require data the provider does not have.
