The Core Question
DAC7 reporting does not determine whether you owe tax — it only determines whether the platform tells your tax authority about your income. Whether that income is actually taxable depends on your national tax law.
The key distinction in most EU countries is:
- Personal sales: selling items you bought for personal use, not primarily for profit → generally not taxable
- Business activity: systematic reselling with the intent to make profit → generally taxable as trading income
Common Signals of Business Activity
Tax authorities look at patterns, not single transactions. Red flags include:
- Frequency: selling dozens of items per month consistently
- Sourcing: buying items cheaply specifically to resell
- Pricing: marking up consistently above what you paid
- Professionalism: using a storefront, brand name, or offering warranties
- Scale: income well above what a private individual clearing a wardrobe would earn
Country Differences
| Country | Key rule | |---|---| | Germany | "Gewerbliche Tätigkeit" if systematic reselling — may trigger trade tax (Gewerbesteuer) | | France | "Activité commerciale" — courts have reclassified heavy resellers as traders (80% penalty) | | Spain | "Actividad económica" — AEAT has sent warning letters to frequent marketplace sellers | | Italy | "Attività commerciale" — AdE distinguishes personal sales from commerce by frequency and intent | | Poland | 6-month personal-item exemption from PIT; systematic reselling may trigger business registration |
Practical Guidance
- Document your original purchase price for every item you resell. If you sell below or at cost, it is hard to argue you are profiting.
- Keep your sales occasional if you want to stay clearly in the personal-sales zone.
- If in doubt, consult a local tax advisor — especially if your income from reselling exceeds a few thousand euros per year.
