DAC8 — EU Crypto Tax Reporting Directive (Applies from 2026)
DAC8 (Directive (EU) 2023/2226) extends the EU's administrative cooperation in tax matters to crypto-assets. From 1 January 2026, EU crypto-asset service providers (CASPs) must report client transactions to national tax authorities, which then exchange information across the bloc. The combined effect of MiCA + DAC8 closes the information gap for crypto-asset taxation that existed for the preceding decade.

Direct answer
What is DAC8 and how does it affect EU crypto users in 2026?
DAC8 (Directive (EU) 2023/2226) extends the EU's administrative cooperation in tax matters to crypto-assets. From 1 January 2026, EU crypto-asset service providers (CASPs) must report client transactions to national tax authorities, which then exchange information across the bloc. Framework: Directive (EU) 2023/2226 (DAC8), amending Directive 2011/16/EU. Scope: All EU crypto-asset service providers + EU residents using CASPs anywhere in the world. Key authority: National tax authorities (BZSt in Germany, DGFiP in France, AEAT in Spain, AdE in Italy, Belastingdienst in Netherlands), with European Commission coordination.

What CASPs must report from 2026
EU CASPs must report annually to their home-state tax authority: identity of each customer (name, tax residence, tax ID), transaction-level data for purchases, sales, and exchanges between crypto-assets, transfers between custodial wallets, and stable-coin / NFT transactions. The reporting is per-customer per-transaction, not aggregated. National authorities then exchange the information with the customer's country of tax residence.
What this closes for tax authorities
Before DAC8, EU tax authorities had limited visibility into citizens' crypto activity beyond what they self-reported. CASPs were not required to share transaction-level data across borders. Investigators relied on third-party reports, blockchain forensics, and increasingly aggressive audit requests. From 2026, EU tax authorities receive standardised CASP-level data on every transaction by every resident — closing the visibility gap almost entirely.
Practical implications for retail crypto investors
Accurate self-reporting becomes essentially mandatory. Mismatches between what a user reports on their tax return and what their CASP reported to the same authority will trigger audit attention with near certainty. Crypto tax software (Blockpit, CoinTracking, Koinly, etc.) becomes operationally necessary rather than optional for anyone with non-trivial transaction history. The "I forgot to report" defence has functionally vanished.
Interaction with MiCA
MiCA requires CASPs to be authorised. DAC8 requires CASPs (now MiCA-licensed) to report to tax authorities. The two regulations together create a tightly integrated regime: only MiCA-licensed CASPs can legally serve EU customers, and those same CASPs must report client tax data. Non-MiCA-licensed providers cannot serve EU retail users, so the DAC8 reporting net does not cover them — but their services are also not legally available to EU retail.
Interaction with national tax rules
DAC8 standardises reporting but does not harmonise national tax law. Germany retains EStG §23 (12-month tax-free for private investors). France retains PFU. Spain retains IRPF + Patrimonio. Italy retains 26% flat. Netherlands retains Box 3 wealth tax. DAC8 just ensures that whatever national rule applies, the tax authority has the data to enforce it.

FAQs
Does DAC8 mean my tax authority knows about all my crypto transactions?
For transactions on EU MiCA-licensed CASPs from 1 January 2026 onward — yes, essentially. CASPs report customer-level transaction data annually to home-state authorities, which share it across the EU. Pre-2026 transactions are not retrospectively reported, though tax authorities may request historical data via existing legal channels.
Does DAC8 apply to non-custodial wallets or DeFi?
Pure non-custodial wallets and decentralised protocols are outside DAC8 scope (no CASP to report). However, on-ramps and off-ramps connecting fiat to crypto remain CASPs and must report the bridging transactions. The information gap remains for purely on-chain activity but closes substantially at the fiat boundary.
Do EU residents using non-EU exchanges still need to comply with DAC8?
Non-EU exchanges are not subject to DAC8 reporting obligations. However, EU residents still owe national tax on their crypto activity regardless of where the platform is based, and pre-existing self-reporting obligations remain. Using non-EU exchanges does not exempt EU residents from tax obligations — it just removes one reporting source.
