The Reseller's Tax Guide: Platform Reporting vs Paying Tax

Important: this article provides general information, reviewed on 9 October 2026. It is not tax, legal or accounting advice. Reporting rules, tax treatment, registration duties and social contributions depend on your country and circumstances. Before acting, check your national tax authority's current guidance or ask a qualified local adviser.

Two different questions are often mixed up: will the platform report my sales? and do I owe tax on them? The first is about data sharing; the second depends on your national tax law.

1. Platform reporting in the EU (DAC7)

Since 1 January 2023, Directive (EU) 2021/514, known as DAC7, has required certain digital platform operators to collect and report information about reportable sellers and activities, including sales of goods. Reports are generally made to the relevant tax authority by 31 January following the reportable calendar year.

For sales of goods, DAC7 defines an excluded-seller test based on both transaction count and total consideration: the platform-facilitated activity must involve fewer than 30 sales and no more than €2,000 during the reportable period. Platforms may still request tax information or apply additional checks, and national reporting obligations can go beyond this summary.

These figures are reporting criteria, not a tax-free allowance. Being reported does not by itself mean that tax is due, and staying below them does not by itself make income tax-free. Tax liability is determined under national law.

2. When might sales be taxable?

National rules often distinguish between disposing of personal belongings and carrying on a trade or business. The legal test varies, but authorities may consider facts such as:

buying items with the intention of reselling them at a profit;
selling regularly and in an organised way;
sourcing stock from wholesalers, charity shops or other platforms to resell.

No single factor decides every case. Frequency, organisation, profit-seeking intention, the type of goods and other income may all matter. Ask the competent tax or business-registration authority in your country if the classification is unclear.

3. National tax, business and social-security rules

DAC7 does not replace national rules. If your selling becomes regular or organised, you may need to consider income tax, VAT, business registration, consumer-law duties and social-security contributions. Small-business or VAT regimes are not automatic exemptions from the other rules, and their conditions can change.

Use the official service for the country where you are resident or established. If you are unsure which country has taxing rights, or you sell across borders, ask the competent authorities or a qualified adviser rather than relying on a platform threshold.

4. UK sellers

The UK has platform-reporting rules that apply to reportable periods beginning on or after 1 January 2024. HMRC explains that platform reporting and tax liability are separate questions. Its guidance uses reporting criteria of at least 30 sales or approximately €2,000 in platform receipts, while the separate trading allowance and Self Assessment rules have their own conditions. Selling personal possessions is not automatically trading, but buying or making goods to resell for profit may be. Use HMRC's online checker or contact HMRC or a UK tax adviser for your circumstances.

5. A simple habit that always helps

Keep records of purchase price, sale price, platform fees, shipping and other costs. Record-retention requirements differ by country, so check what documents you must keep and for how long with your tax authority or adviser.
