Key Takeaways
- Platform operators must file DAC7 reports by 31 January each year, covering seller income from the preceding calendar year.
- Sellers with fewer than 30 transactions and below €2,000 in total consideration in a calendar year are exempt from reporting.
- Non-EU platforms facilitating sales to EU-resident sellers must register in at least one EU member state or face permanent revocation of their registration after two formal reminders.
- The directive covers four activity categories: sale of goods, rental of immovable property, personal services, and rental of transport.
What is DAC7 (Platform Reporting)?
DAC7 transposes the OECD Model Rules for Reporting by Platform Operators into EU law. It applies to any digital platform (whether EU-based or not) that facilitates transactions for sellers resident in the EU. The platform operator must collect each reportable seller's identity details, tax identification number, VAT registration number, and financial account information, then verify this data against available records before filing. Directive 2021/514, Annex V, Section II sets out the due diligence procedures the operator must follow.
For auditors, DAC7 creates two distinct pressure points. First, platform-operating clients must account for the compliance costs (IT systems, data verification workflows, penalty exposure, and external advisory fees) and potential penalties for non-compliance, which may affect uncertain tax positions or provisions under IAS 37. Second, all clients who sell through digital platforms now face increased tax authority scrutiny, because the data reported under DAC7 gives revenue authorities a direct comparison between declared income and platform-reported consideration. Where a seller's tax return understates revenue relative to DAC7 data, the resulting tax adjustment affects current tax and potentially deferred tax under IAS 12.
Worked example: Rossi Alimentari S.p.A.
Client: Italian food production company, FY2025, revenue €67M, IFRS reporter. Rossi operates a direct-to-consumer online store on its own website (not subject to DAC7, as it is not a multi-seller platform) but also sells artisanal products through two third-party EU marketplaces: a German platform and a French platform. Combined marketplace sales total €4.2M.
Step 1 — Identify DAC7 exposure: Rossi is a reportable seller, not a platform operator. Both the German and French platforms are required to report Rossi's seller details and total consideration to their respective tax authorities. The audit team confirms that Rossi provided its Italian TIN and VAT number to both platforms.
Documentation note: record the platforms on which the client operates, the member states where each platform is registered, the seller information provided by Rossi, and the total consideration reported per platform. Cross-reference to the revenue reconciliation working paper.
Step 2 — Reconcile platform-reported income to the financial statements: The German platform issued a DAC7 annual statement showing €2.9M in gross consideration for FY2025. The French platform reported €1.3M. Combined: €4.2M. Rossi's general ledger shows €4.15M in marketplace revenue after deducting €50,000 in credit notes issued in December 2025 for returned goods. The €50,000 difference is supported by credit note documentation.
Documentation note: obtain the DAC7 annual statements from both platforms (or request them from Rossi's finance team). Reconcile the platform-reported gross consideration to Rossi's recorded marketplace revenue. Document the nature of any differences and attach supporting credit notes. Reference ISA 500.7 on the reliability of external evidence.
Step 3 — Assess tax risk from DAC7 data sharing: The Italian tax authority (Agenzia delle Entrate) receives the DAC7 data through automatic exchange. The reconciled difference (€50,000 in credit notes) is immaterial relative to total revenue and is fully documented. No incremental tax exposure arises. However, if Rossi had failed to declare the marketplace revenue, the DAC7 data would have flagged the discrepancy directly.
Documentation note: record the conclusion on tax risk arising from DAC7 data exchange. Note that the Italian authority has access to both platforms' reports and that the reconciliation supports the declared revenue position. File under the tax risk assessment section of the audit file.
Conclusion: the DAC7 reconciliation confirms that Rossi's declared marketplace revenue aligns with the platform-reported consideration, with a documented and immaterial difference attributable to credit notes issued in the normal course of business.
What reviewers and practitioners get wrong
- Audit teams frequently overlook DAC7 as a source of external audit evidence. The annual statements issued by platforms to reportable sellers provide third-party confirmation of gross consideration that can be reconciled to the client's revenue ledger. ISA 500.A31 recognises that information obtained from a source independent of the entity is generally more reliable. Where the client sells through platforms, requesting the DAC7 seller statements is a low-effort procedure that strengthens the revenue completeness assertion.
- Practitioners auditing platform operators sometimes treat DAC7 compliance as a pure IT matter and fail to assess the financial statement impact of non-compliance. Penalties for reporting failures vary by member state but can be significant (Germany imposes fines up to €50,000 per infringement under Section 25 of the Platform Tax Transparency Act). Where the operator has not complied, the auditor should evaluate whether a provision under IAS 37.14 is required for probable penalties and whether the non-compliance affects the going concern assessment if registration revocation is a realistic outcome.

Frequently asked questions
Does DAC7 apply to a company that only sells on its own website?
No. DAC7 applies to platform operators that facilitate transactions between sellers and buyers. A company selling exclusively through its own single-seller website is not operating a platform within the directive's definition. The obligation arises when a platform connects third-party sellers with buyers and facilitates the underlying transaction. Directive 2021/514, Annex V, Section I(A)(1) defines the term "platform" for this purpose.
What should an auditor do when a client cannot obtain its DAC7 seller statement from a platform?
Request the client to contact the platform operator directly, as Annex V, Section III(B) requires the platform to communicate the reported information to each seller by 31 January. If the statement remains unavailable, the auditor can use alternative procedures under ISA 500.A22, such as reconciling the client's own records of platform sales to bank receipts from the platform's payment processor. Document the inability to obtain the statement and the alternative procedures performed.
How does DAC7 interact with VAT reporting obligations?
DAC7 is an income tax transparency measure, not a VAT compliance instrument. However, the data collected (seller identity, consideration amounts, transaction counts, and member state of residence) overlaps with information relevant to VAT obligations. Tax authorities can cross-reference DAC7 data with VAT returns to identify sellers who exceed VAT registration thresholds but have not registered. For the auditor, this means DAC7 data may trigger VAT assessments that create additional uncertain tax positions under IAS 12 (incorporating IFRIC 23).
