DAC7 reporting UK: when platforms tell HMRC

DAC7 is the EU/UK ruleset that pushes online marketplaces to report certain sellers' activity to tax authorities. In practice, that means platforms like Vinted, eBay, Etsy, and Depop may send HMRC a summary of how much you sold and how many transactions you made — automatically.

The question sellers actually ask is: “When does Vinted report me to HMRC?” The answer is about thresholds, not about whether you “feel” like a business.

The reporting thresholds

Under the model rules UK platforms follow, reporting is generally triggered when, in a calendar year, you go over either:

• About €2,000 in sales (roughly £1,700), or
• 30 or more transactions / items sold

Hit either line and the platform may report. You do not get a dramatic email saying you owe tax. Reporting is information-sharing. HMRC already receives a lot of third-party data; DAC7 makes marketplace sales harder to ignore.

Reporting is not a tax bill

This is the bit that causes panic. Being reported does not automatically mean you owe money. Tax depends on whether you were trading and whether you made taxable profit after costs — including the £1,000 trading allowance.

Example: you sell 35 of your own old dresses for a total of £900 with almost no profit. You may trip the 30-item reporting line while still being under the trading allowance and potentially not owing income tax on a clear-out. Conversely, you could stay under 30 sales, earn £1,200 of trading profit, and still need to think about tax even if no DAC7 report fired yet.

What you should do

Track gross sales and item count across platforms. Use the Tax & HMRC fields in the profit calculator to see DAC7 headroom after this sale. Keep it separate in your head from fee shopping — Vinted fees and eBay fees affect profit; DAC7 affects visibility to HMRC.

Not financial advice. Thresholds and FX conversion can move; treat ~£1,700 / 30 as the working model our calculator uses, then confirm against your platform's seller help pages if you are close to the line.
