Short answer

DAC8 extends EU automatic tax-information exchange to crypto. EU-based CASPs (the same regulatory class licensed under MiCA) must report customer transaction data to their home Member State for tax year 2026 onwards. First reports due 31 January 2027. The directive implements the OECD Crypto-Asset Reporting Framework (CARF) almost verbatim, so the same reporting shape is being adopted in ~60 non-EU jurisdictions on parallel timelines. For most EU users, the practical change: your tax authority will start receiving annual aggregate- transaction data on your crypto holdings, cross-checked against your filing.

What DAC8 is

DAC8 — formally Council Directive (EU) 2023/2226 of 17 October 2023 amending Directive 2011/16/EU on administrative cooperation in the field of taxation — extends the EU\'s existing Directive on Administrative Cooperation (DAC, "DAC1" through "DAC7") to cover crypto-assets. Each iteration of the directive has expanded the scope of automatic information exchange between EU Member States\' tax authorities:

DAC1 (2011, original) — five categories of non-financial income (employment, directorship, pensions, life insurance, real estate)
DAC2 (2014) — financial-account information, aligning with OECD CRS
DAC3 (2015) — cross-border tax rulings + advance pricing agreements
DAC4 (2016) — country-by-country reporting for multinationals
DAC5 (2016) — beneficial-ownership AML data access
DAC6 (2018) — cross-border reportable tax arrangements (intermediaries)
DAC7 (2021) — digital-platform sellers (Airbnb, Etsy, Vinted, Uber)
DAC8 (2023) — crypto-asset service providers + e-money + CBDC

DAC8 also incorporates the OECD\'s Crypto-Asset Reporting Framework (CARF), which the OECD adopted in 2022 as a global multilateral standard. The EU was the first bloc-level adopter; the UK, Switzerland, Japan, Singapore, Canada, Australia, and ~50 other jurisdictions are implementing CARF on parallel timelines, mostly with effective dates of 2026 or 2027.

What reporting actually looks like

For each customer who is an EU tax resident, the reporting CASP must collect and report the following annually:

Customer identification (collected at onboarding, refreshed on change)

Full legal name
Address of residence
Tax Identification Number (TIN) issued by residence country, plus the issuing country code
Date of birth (individuals) OR business registration number + place of establishment (entities)
For entities: identification of controlling persons where required

Transaction data (aggregated per calendar year, per crypto-asset)

Gross fair-market value of acquisitions in EUR
Gross fair-market value of disposals in EUR
Number of units involved in each direction
Aggregate fair-market value of crypto-to-crypto exchanges
Aggregate fair-market value of retail-payment uses (paying for goods/services in crypto)
Aggregate fair-market value of transfers in and out (to wallets not at the CASP)
Year-end balance per crypto-asset

Reporting is aggregate per calendar year per crypto-asset, NOT transaction-by-transaction. EUR fair-market valuations follow a methodology published by each Member State (typically the year-end closing price on a recognised reference index).

Who is required to report

DAC8 applies to "Reporting Crypto-Asset Service Providers" — broadly:

Entities established in the EU that provide crypto-asset services (custody, exchange, transfer, placement)
EU branches of non-EU CASPs offering services to EU customers
Non-EU CASPs that effectively offer services to EU customers without an EU branch must appoint an EU representative for DAC8 purposes; failure to do so creates exclusion-from-EU consequences (typically loss of access via national-level enforcement)

In practical terms: every operator licensed under MiCA is a DAC8 Reporting CASP. Pre-MiCA national-licensed CASPs that still operate during the MiCA grandfathering window are also covered. Self-custody wallets and software-only wallet providers that do not custody customer assets are generally outside scope.

Timeline

October 2023: Council adopts DAC8. EU Member States required to transpose into national law by 31 December 2025.
During 2025: National transposition. Germany, France, Spain, Italy, Netherlands, and most large Member States completed by Q3-Q4 2025; some smaller states slipped into early 2026.
1 January 2026: First reporting period begins. CASPs must begin tracking customer transactions for DAC8 reporting from this date.
31 January 2027: First reports due to home Member State\'s tax authority.
Throughout 2027: First wave of cross-border data exchange between Member State tax authorities under the DAC8 mechanism.

What this means for an EU user

Most retail EU crypto users will not need to take separate action at filing time. The CASP\'s DAC8 report gives the tax authority the data; the user files their own return as before. Practically you SHOULD:

Verify your TIN is on file with every EU-based CASP you use. CASPs will ask for this at onboarding under DAC8 KYC requirements; existing customers will be re- documented during 2025-2026. Don\'t ignore the re-KYC requests.
Keep your own transaction records. The CASP\'s aggregate report won\'t match your filing one-to-one — it doesn\'t distinguish between a taxable disposal and a non- taxable transfer to your own wallet. If your tax authority sees aggregate disposals on the CASP report that don\'t appear in your filing, you may need to explain the difference. Crypto-tax software (see our ranking) handles the per-transaction reconciliation; the CASP report is the cross-check.
File your annual return. DAC8 does NOT replace your filing obligation; it gives your tax authority the data to cross-check against your filing.
Understand the multi-jurisdiction case: if you hold crypto at CASPs in multiple EU countries, each CASP reports to its home tax authority, which then exchanges with your residence-country authority. The data converges at your home authority.

Penalties

DAC8 itself sets only a general non-compliance framework; penalty levels are set by each Member State under national tax-procedure law. Typical penalty regimes range:

Germany: €5,000–€50,000 per missing report under §379-§380 AO + general tax-procedure penalties
France: €15,000–€50,000 per missing report under CGI Article 1736
Spain: up to 150% of the omitted amount where applicable + €600,000 maximum fines for severe non-compliance
Italy: 3-15% of the undeclared value, doubled for tax-haven sourcing
Netherlands: penalties calibrated to Belastingdienst general framework

Verify your residence-country\'s specific penalty regime; this list is illustrative and evolves as Member States issue implementing guidance.

Country-specific cross-references

For country tax frameworks that interact with DAC8 reporting, see:

Switzerland is NOT in DAC8 scope (non-EU) but IS implementing OECD CARF on its own timeline — see Crypto Taxes Switzerland. The UK is in the same parallel position; the UK\'s CARF implementation is expected from 2027 onwards.

Frequently asked questions

What is DAC8? +

DAC8 is Council Directive (EU) 2023/2226, adopted October 2023, which amends Directive 2011/16/EU on administrative cooperation in the field of taxation. It extends the EU's existing automatic-exchange-of-information regime — previously covering bank accounts, dividends, and pension data — to crypto-asset transactions and balances. Under DAC8, EU-based Crypto-Asset Service Providers (CASPs, the same regulatory class licensed under MiCA) must collect and report customer transaction data to their home Member State's tax authority; that authority shares the data with the customer's residence-country tax authority across the EU.

When does DAC8 actually take effect? +

DAC8 applies to tax year 2026 (i.e., transactions from 1 January 2026 onward). The first reports CASPs must submit are due 31 January 2027 for 2026 activity. Member States had until 31 December 2025 to transpose DAC8 into national law; most did so during 2025 (Germany, France, Spain, and Italy completed transposition by Q3 2025; some smaller states slipped into early 2026). Penalty regimes for non-compliance follow each Member State's general tax-procedure law.

What does DAC8 reporting actually cover? +

For each customer who is an EU tax resident, the CASP reports: identifying information (name, residence address, tax-identification number, date of birth for individuals or business registration number for entities); per-crypto-asset aggregate values of acquisitions, disposals, exchanges, transfers, and retail-payment uses during the calendar year; type of crypto-asset (e.g., Bitcoin, Ether, USDC) and fair-market value in EUR using a published valuation methodology. The reporting is aggregate per calendar year, NOT transaction-by-transaction. It implements the OECD Crypto-Asset Reporting Framework (CARF) almost verbatim, so global alignment is high.

How is DAC8 different from FATCA, CRS, and MiCA? +

FATCA is the US-specific reporting regime requiring foreign banks to identify and report US-person account holders to the IRS. CRS (Common Reporting Standard) is the OECD's multilateral fiat-bank-account version. DAC8 extends the same automatic-exchange concept to crypto and aligns with OECD CARF — so it complements rather than replaces CRS. MiCA is the EU's licensing framework for CASPs (operational rules, capital requirements, conduct rules); DAC8 is the tax-reporting framework that CASPs operating under MiCA (or equivalent national licences) must also comply with. A platform serving EU customers needs both: MiCA for the licence to operate, DAC8 for the tax-reporting obligation.

Do I need to do anything as a user? +

In most cases no separate user action is required at filing time — CASPs collect KYC information at onboarding and update it on demand, then submit reports automatically. What you SHOULD do: (1) ensure your residence-country tax-identification number is on file with every EU-based CASP you use; (2) keep your own transaction records, because the CASP's aggregate report may not match your interpretation of acquisitions vs. transfers; (3) continue to file your annual return as required by your residence country — DAC8 reporting does NOT replace your filing obligation, it gives your tax authority the data to cross-check against your filing. Discrepancies between your reported gains and the CASP's reported activity will get attention from the tax authority.

Does DAC8 apply to non-EU platforms? +

DAC8 directly binds EU-established CASPs (those licensed under MiCA or pre-MiCA national regimes). However, there are two important extensions: (a) non-EU platforms that serve EU customers are subject to a separate provision requiring them to either appoint an EU representative for DAC8 purposes OR be effectively excluded from offering services to EU customers; and (b) the OECD CARF (which DAC8 implements) is being adopted by ~60 non-EU jurisdictions including the UK, Switzerland, Japan, Singapore, Canada, and Australia on parallel timelines (most coming into force 2026 or 2027). The practical result for an EU customer using a non-EU platform: the platform either reports to its home jurisdiction under that jurisdiction's CARF, which then exchanges with the EU under DAC8's broader information-exchange architecture, or the platform exits the EU market.
