DAC7 is an EU reporting rule that has quietly become one of the most important compliance obligations for online marketplaces and the accountants who advise them. If you sell goods or services through a digital platform, or you work with clients who operate one, DAC7 determines what gets reported to tax authorities — and when. It's an increasingly common topic for finance professionals studying international tax as part of ACCA or advising SME clients on digital business models.
What is DAC7?
DAC7 is the seventh update to the EU's Directive on Administrative Cooperation (Council Directive (EU) 2021/514). It entered into force on 1 January 2023 and requires digital platform operators to collect, verify and report information about sellers using their platform to earn income — then share that data automatically with EU tax authorities, who exchange it with each other.
Who has to report under DAC7?
DAC7 applies to two categories of platform operator:
- Union platform operators — platforms resident, incorporated, managed, or with a permanent establishment in an EU member state.
- Non-Union platform operators — platforms based outside the EU that facilitate relevant activity by EU-resident sellers or the rental of EU property, but that don't meet the Union criteria. These operators must register with a single EU member state rather than register separately in each one.
Certain platforms are excluded, such as those where the operator can demonstrate its business model doesn't allow sellers to profit (for example, some strictly non-commercial listing sites), but the exclusions are narrow and need to be assessed carefully rather than assumed.
What activities and data are covered?
DAC7 covers four categories of activity carried out through a platform: rental of immovable property, personal services, sale of goods, and rental of any mode of transport. For each reportable seller, the platform operator must collect identification details (such as name, address, tax identification number and, for individuals, date of birth) and financial information, principally the total consideration paid or credited to that seller during the reporting period, along with any fees, commissions or taxes withheld by the platform.
Reporting deadlines and first exchanges
Platform operators must report the required information no later than 31 January of the year following the reportable calendar year — so, for example, income earned in 2026 must be reported by 31 January 2027. The first information exchanges between EU tax authorities under DAC7 took place at the end of February 2024, covering the 2023 reporting year, and the same annual cycle now repeats every year.
Penalties for non-compliance
Because DAC7 is implemented through domestic legislation in each EU member state, exact penalties vary by country, but the Directive requires member states to have administrative and, where appropriate, penal sanctions available for non-compliant platform operators. A platform that fails to comply after receiving two reminders can have its registration permanently revoked, and member states can coordinate to prevent a non-compliant non-Union platform operator from carrying on relevant activity across the EU.
Why this matters for accountants and finance teams
DAC7 has a direct, practical impact on two groups of clients accountants regularly advise: platform operators themselves, who need robust seller due-diligence and reporting processes, and individual sellers using platforms, whose income is now visible to tax authorities in a way it often wasn't before. For sellers who may not have been declaring platform income accurately, DAC7 significantly raises the risk of a mismatch between reported platform data and their tax return, which is exactly the kind of discrepancy that triggers a compliance check.
How DAC7 fits into the wider compliance picture
DAC7 sits alongside other data-driven compliance and reporting obligations finance professionals increasingly encounter, including GDPR-driven data handling requirements around the personal information platforms must now collect, and broader anti-money laundering due diligence obligations covered in guides like AML for accountants. Firms building out digital platform advisory services need to treat DAC7 not as an isolated tax rule but as one part of a wider seller-verification and data-governance framework.
It's also worth noting that DAC7's reporting model — automatic collection at source by the platform, followed by automatic exchange between tax authorities — mirrors the approach already used for financial account information under the Common Reporting Standard. For finance professionals already familiar with CRS-style reporting, DAC7 is best understood as that same logic extended to the digital platform economy, rather than as an entirely new compliance concept.
FAQs
Does DAC7 apply to platforms based outside the EU? Yes, if they facilitate relevant activities by EU-resident sellers or EU property rentals — these are treated as non-Union platform operators and must register in one EU member state.
Does DAC7 create a new tax? No. It is a reporting and information-exchange obligation, not a new tax. It increases the data tax authorities hold; it doesn't itself change what's taxable.
What should sellers do if they receive a DAC7 data request from a platform? Respond promptly and accurately — platforms are legally required to collect this information and can restrict or close accounts of sellers who don't provide it.
DAC7 has made platform income far more visible to tax authorities across the EU, and accountants advising both platform operators and individual sellers need a working understanding of what's being reported, to whom, and when.
