Selling on eBay, Vinted or Etsy: what HMRC platform reporting means for small sellers

If you sell through eBay, Vinted, Etsy or Airbnb, or you run a small online shop that also lists on marketplaces, your sales data may already be sitting with HMRC. This is not a new tax and it is not a crackdown on clearing out your wardrobe. It is a change in who tells HMRC what. Here is a plain guide to what is reported, what counts as trading, and what a small seller should do.

What actually changed

HMRC's own guidance for online sellers is blunt on the first point: "There is no new tax for online selling." What changed is reporting. Digital platforms such as eBay, Vinted and Airbnb must send HMRC sales data and some personal information about their sellers. The rules took effect at the start of 2024, and the first reports, covering 2024, were due by the end of January 2025.

According to HMRC, platforms report sellers who sold at least 30 items, or earned roughly £1,700 (about €2,000), in the year. Paid services, such as holiday lets, are included. Sellers are told when their information has been shared, and the platform gives them a copy.

The earlier consultation behind these rules also described the approach: platforms collect and check seller details, report to HMRC and to the seller by 31 January each year, and keep records for at least five years. It proposed penalties for platforms that get this wrong, not for sellers as such.

Being reported is not the same as owing tax

This is the point that causes the most worry. HMRC says sharing your data does not automatically mean you must complete a tax return. Whether you owe anything depends on what you are doing, not on whether a platform sent a report.

There are two quite different situations:

• Selling your own things. Items you owned for your own use, such as clothing, furniture, jewellery or phones, usually carry no Income Tax when sold. Capital Gains Tax may apply if a single item, or a set of items, sells for more than £6,000. HMRC says that selling unwanted items worth under £6,000 each is unlikely to need reporting, however many you sell.
• Trading. You are probably trading if you buy goods intending to resell them at a profit, or if you make goods to sell, including as a hobby. Services such as tutoring, cleaning, gardening, dog walking or delivery work count too, as does creating online content such as videos, podcasts or influencing, including gifts or services received for promoting products.

The £1,000 trading allowance

If you are trading, the trading allowance is the number to know. It is a tax exemption of up to £1,000 per tax year, and it is a single allowance: income from goods, services and content is added together before you compare it with £1,000.

• £1,000 or less in gross income: you generally do not need to tell HMRC or declare the income, but you must still keep records of it.
• More than £1,000: you need to tell HMRC, and you can register for Self Assessment. You may deduct the £1,000 allowance instead of your actual expenses, but if your real expenses are higher than your income, claiming expenses may work out better.

"Gross income" means the total before expenses, so a seller who turns over £1,400 but makes only £200 profit is still over the line. The allowance cannot be used if the trading income comes from a company you or a connected person own or control, a partnership you or a connected person are in, or your employer or your spouse's or civil partner's employer. HMRC also notes that the tax year runs from 6 April to 5 April, while some platforms report on calendar years, so you will need to recalculate your totals before checking your position.

For Self Assessment, HMRC says to register by 5 October following the end of the tax year in which your gross trading income went over £1,000. Using the allowance reduces taxable income for things like tax credits and student loan repayments, but it does not affect income for Universal Credit.

A worked example

Suppose someone buys vintage clothing at car boot sales and resells it on Vinted. Over a tax year they sell 45 items for a total of £2,300. The platform will have reported them, because they passed 30 items. Because they bought the items to resell, this is trading, and £2,300 is above £1,000, so they need to tell HMRC. They would compare two options: deduct the £1,000 allowance, or deduct what they actually spent on stock, postage and packaging, whichever is larger.

Now take someone who sold 45 unwanted items from their own home, each worth well under £6,000. The platform may still report them, but HMRC's guidance suggests that is unlikely to need reporting as income. They should keep a note of what they sold and move on.

What to do this week

• Check your platform notifications. Look for any message saying your information has been shared with HMRC, and download your sales history.
• Add up your income by tax year. Convert calendar year platform totals to 6 April to 5 April, and include every source: marketplaces, your own website, services and content.
• Use HMRC's free checking tool. The GOV.UK guidance links to it, and it explains how to report if you need to. HMRC says the tool does not store the information you enter.
• Keep records. HMRC says to keep invoices, spreadsheets, bank statements or payment statements. It can issue penalties for records that are inaccurate, incomplete or unreadable.
• Separate the money. A dedicated bank account for selling makes the totals far easier to prove.
• Ask an accountant if it is unclear. Mixed situations, such as personal items plus stock you bought to resell, are where advice pays for itself.

What the mood looks like

Coverage of these rules has been mixed. Some outlets have framed them as a crackdown, while advisers largely stress that no rate or allowance changed and that only HMRC's visibility did. The calmer reading matches what HMRC itself says: no new tax, and clearing out unwanted belongings changes nothing.

If you are growing beyond a side hustle

Marketplaces are a good way to test demand, but they hand you little control over your customers, your data or your margins. Once sales are steady, many sellers move to their own shop so they can own the customer relationship and see their figures in one place. If that sounds like your next step, our ecommerce services page explains what building a shop involves. Either way, the tax position starts the same: know your gross income, know which side of £1,000 you are on, and keep tidy records.
