How Are Tax Authorities Using DAC7 Data?
Since the first round of DAC7 reports was filed in January 2024, tax authorities across the EU have been cross-referencing platform data against declared income. Enforcement approaches vary by country, but share common elements.
France: The Airbnb Precedent and DGFiP Letters
France was an early mover. In 2019 — before DAC7 — Airbnb settled with French tax authorities for €167 million in back taxes and penalties related to undeclared income from hosts. This established the legal precedent that platform income is trackable and taxable.
Post-DAC7 (2022–2024), the DGFiP (Direction Générale des Finances Publiques) sent "mises en demeure" (formal notices) to thousands of eBay and Vinted sellers whose declared income did not match platform data. Sellers who failed to respond faced the "activité occulte" (hidden activity) penalty — an 80% surcharge on unpaid tax, the maximum under French law.
Spain: Operación Marketplace
Spain's tax agency AEAT ran "Operación Marketplace" targeting heavy sellers on Wallapop and eBay before DAC7. After January 2024, they sent "cartas de aviso" (warning letters) to sellers whose platform income in 2023 exceeded the reporting threshold but was not found in their income tax filings. Most cases were resolved with voluntary disclosure; some led to formal inspections.
Italy: AdE Compliance Notices
The Italian tax agency (Agenzia delle Entrate) began sending "comunicazioni di compliance" in 2024 — automated letters informing sellers that discrepancies were detected between their DAC7-reported income and their declared income. The letters offer a 30-day window to either amend the return or provide an explanation. Italy's fines for non-compliance range from €3,000 to €31,500 — imposed on platforms, not sellers.
Germany: Finanzamt Kontrollmitteilungen
German tax offices (Finanzämter) issued Kontrollmitteilungen (control notices) after receiving PStTG (the German DAC7 transposition) data. The infamous 2024 media storm over the €300 million alleged tax evasion linked to platform sellers on Airbnb, Uber, and Etsy drove significant public attention to DAC7 in Germany, though many reported figures conflated corporate and individual tax gaps.
Poland: KAS Verification Letters
Poland's National Revenue Administration (Krajowa Administracja Skarbowa, KAS) began issuing "czynności sprawdzające" letters in 2024 — verification requests to sellers. Poland has not yet seen DAC7-specific court cases, but the KAS has publicly stated it is processing the 2023 data and will continue systematic checks.
What This Means for You
These cases share a common pattern: the initial contact is usually a letter, not a raid. The authority gives you a chance to explain or correct. Sellers who respond proactively and honestly typically resolve matters without penalties. Those who ignore letters face escalation.
If your income crosses the DAC7 threshold, the safest approach is to know your position in advance — which is what our calculator helps you do.
