What Information Does a Crypto Platform Report Under DAC8?

Under DAC8, the eighth amendment to the EU's Directive on Administrative Cooperation, a reporting crypto-asset service provider sends its national tax authority two sets of data about EU-resident users: who they are (name, address, tax residence, tax identification number, date of birth) and what they did, as yearly totals per crypto-asset. The list is built around transactions rather than holdings, and reporting is not the same as taxation.

Key takeaways

• Providers report two blocks: your identity with tax residence and tax identification number (TIN), and yearly totals per crypto-asset for purchases, sales, exchanges and transfers.
• The report holds totals by asset and category, not a line-by-line trade history.
• Stablecoins, including e-money tokens, and certain NFTs are in scope. The list is transaction-based, with no headline field for wallet balances.
• Reporting is not taxation. Whether a swap or a transfer is taxable is a question for national tax law.
• Providers started collecting data on 1 January 2026. Reports for 2026 fall due during 2027, and tax authorities exchange them across borders by 30 September 2027.

What information can be reported under DAC8?

DAC8 is Council Directive (EU) 2023/2226. It applies from 1 January 2026, follows the OECD's Crypto-Asset Reporting Framework, and puts the duty on reporting crypto-asset service providers: MiCA-authorised providers plus other operators of crypto-asset services that must register once in a Member State. This page answers one narrower question: what exactly goes into the report.

Identity information

Providers collect and report the user's name, address, country of residence, TIN and, for individuals, date of birth, with place of birth where available. For a company, the report covers the entity and its controlling persons, including their role. Some users fall outside reporting, among them listed companies, governments and central banks, according to Ireland's tax authority, which also requires providers to send each reported user a copy of what was filed.

Tax residence and TIN

A provider must obtain a self-certification of your tax residence and TIN and test it for reasonableness. If you are resident in several countries, each one and its TIN is recorded, and the Commission confirms that residents of the provider's own Member State are included too. DAC8's due-diligence rules, which follow the OECD framework, can require a provider to stop a user's reportable transactions if the self-certification is still missing after two reminders and 60 days from the first request, so answer onboarding questions promptly.

Transaction information

DAC8 reporting is aggregated. According to the European Commission, the information is broken down for each reportable crypto-asset and includes quantitative items such as the aggregate gross amount paid or received for acquisitions and disposals against fiat or other reportable crypto-assets, or the aggregate fair market value for transfers.

An illustration with invented figures: in 2026 a user pays €6,000 in total, over four purchases, for 0.12 units of one coin, and sells 0.04 units for €2,500. The report would show one acquisition total (€6,000, 0.12 units, four transactions) and one disposal total (€2,500, 0.04 units, one transaction), without dates or individual prices. National rules can ask for more: Estonia requires extra information so that capital gains and losses can be calculated.

Crypto-to-fiat transactions

Every purchase or sale made against money counts. Buying with euros is an acquisition against fiat, and cashing out to a bank account (for example by SEPA transfer) is a disposal against fiat. Each direction is totalled separately per crypto-asset, in the fiat amount actually paid or received.

Crypto-to-crypto transactions

A swap has no fiat leg, so the report values it at fair market value. Treat it as a disposal of the asset you gave up and an acquisition of the asset you received, each totalled by asset. Several countries can tax a swap even though no money touched a bank account, which is why authorities want the values.

Transfers

Transfers into and out of your account are reported as totals per asset, with fair market value, units and number of transfers, and split by type (for instance an airdrop or staking reward) where the provider knows it. Transfers to addresses that the provider does not know to be linked to another service provider are totalled separately.

Stablecoins

Stablecoins are not excluded. The European Commission states that DAC8 covers stablecoins, including e-money tokens, together with certain non-fungible tokens.

Buying a euro- or dollar-referenced stablecoin with euros is therefore an acquisition against fiat, and swapping it for another token is a crypto-to-crypto exchange. A stable price does not make the transaction invisible. Our guide to USDC and euro cross-border payments covers those flows.

NFTs

NFTs are reportable when they can be used for payment or investment purposes. Providers assess this per token: a crypto-asset is reportable unless the provider has adequately determined that it cannot be used for payment or investment, and central bank digital currencies and traditional electronic money are excluded. A pure access pass may fall outside; a collectible traded as an investment may not.

Does DAC8 report your wallet balance?

No, not as a headline item. The Commission describes the report as transaction totals per asset (acquisitions, disposals and transfers), and the OECD framework it builds on requires reporting of certain transactions rather than of assets held. The balance in your account at year-end is not on that list.

The list of items that Irish Revenue publishes for providers (identity, tax residence, and totals for purchases, sales, transfers and retail payments) contains no balance either. Two caveats: national legislation may ask for more than the minimum, as Estonia's gains-and-losses requirement shows, and a balance can still reach a tax authority by other routes such as bank records or your own declaration.

Are all wallet-to-wallet transfers taxable?

No, and DAC8 does not decide that. Reporting and taxation are separate: DAC8 only obliges providers to pass information to tax authorities, while taxability is settled by national tax law, case by case.

A withdrawal from a provider to an external address appears as a transfer total, which tells the authority that value left, not whether you own the destination. A transfer between two self-hosted wallets with no provider involved is not reported by any provider under DAC8, though it stays visible on public blockchains and subject to national rules. If your country treats moves between your own wallets as neutral, your own records showing that both wallets are yours make that easy to explain.

What happens to the data?

A reporting provider files its report in one Member State only. That national tax authority keeps the data on its own residents and passes the data on users resident elsewhere to the tax authority of their country of residence, within nine months of the end of the reporting year.

The sequence is: user → reporting provider → national tax authority → tax authority of the user's country of residence. Beyond the EU, the Commission notes that 76 Global Forum members had announced by March 2026 that they intend to exchange crypto-asset data under the OECD framework.

When will 2026 data first be reported?

Filing deadlines and extra requirements are national, so check your own tax authority's guidance.

What should users keep records of?

This is record-keeping, not tax advice. Your own records let you check what a provider reports and answer questions from a tax authority.

1. Confirmations or statements for every purchase and sale: date, asset, units, and fiat amount.
2. Records of swaps, with both assets and the market values used.
3. Transfer histories in and out, noting whose wallet each address belongs to.
4. Evidence of staking rewards, airdrops and other receipts, with the date received.
5. Fees paid, shown separately, and each provider's year-end report kept beside your own figures.

How a provider like Quppy fits in

Quppy's website attributes European crypto-asset services to Payhound Limited, a Malta-based crypto-asset service provider authorised under MiCA. MiCA-authorised providers fall within DAC8's definition of reporting providers, so a user of such a service should expect tax-residence questions at onboarding; to check a provider's status, see how to verify a crypto platform's MiCA authorisation. How the self-certification is collected and what year-end statements are issued are details to confirm in the onboarding flow and Terms.
