Selling on Vinted, eBay and Etsy at the Same Time: How Your Tax Works Across All Platforms

If you sell across more than one platform, you've probably done the mental maths at least once. Vinted is fine, eBay is fine, Etsy feels fine. Each one separately seems well within whatever limit you think applies. Then someone mentions tax and you're suddenly not sure whether you need to add them all up or whether each platform is treated separately.

They all add up. There is one £1,000 trading allowance for the whole tax year across every platform combined. One set of records. One Self Assessment return. Your activity on Vinted, eBay, Etsy, Depop or any other platform is treated as a single pool of trading income, not as four separate businesses that each get their own allowance.

This catches a lot of multi-platform sellers out. Each platform in isolation looks manageable. Combined, the picture is different.

Why Multi-Platform Selling Changes the Maths

Someone selling on a single platform has a relatively straightforward picture. Enter the gross income, compare it to £1,000, decide whether to claim the trading allowance or actual expenses, and move on.

Multi-platform sellers have the same rules but a more complicated input. The gross income you need to compare to the £1,000 threshold is the sum of your gross income across every platform where you sold something in the tax year. Car boot sales and cash sales count too, if they're part of the same trading activity.

Here is what that looks like in practice.

That seller has a decision to make. They're over the threshold. They either claim the £1,000 trading allowance and pay tax on the remaining £520, or they claim their actual expenses, platform fees, postage, packaging, cost of stock, and pay tax on what's left after those come off the gross income. Our post on when not to claim the trading allowance covers how to make that decision properly.

Calculate Your Combined Position

Use the calculator below to see where you stand across your platforms.

How Gross Income Works Differently on Each Platform

The calculator asks for gross income, not what you received into your bank. Each platform calculates this differently, and getting it right matters for an accurate combined figure.

Vinted charges sellers no fees. The buyer pays a buyer protection fee on top of your listing price. Your gross income is the listing price you set. If you listed something for £25 and it sold, your gross income is £25 regardless of what the buyer paid overall.

eBay deducts its Final Value Fee (approximately 12.8% on most categories) from the seller's payout. Your gross income is the full sale price including buyer-paid postage, not the net amount that lands in your account after fees. If something sold for £40 and you received £34.88 after fees, your gross income is still £40. The fees are an expense that reduces your profit, not a reduction in gross income.

Etsy deducts transaction fees (6.5%), payment processing fees (4% plus 20p) and a listing fee (18p per item). Same principle as eBay: your gross income is the full sale price, not the net payout.

Our posts on finding your gross sales on Vinted and the bank balance versus profit distinction cover this in more detail for each platform.

The DAC7 Reporting Rules Across Multiple Platforms

Each platform reports to HMRC independently under the DAC7 rules. Vinted reports what you sold on Vinted. eBay reports what you sold on eBay. HMRC then combines those reports when they match data to your tax record.

This means HMRC can see your combined picture even if no single platform shows income above the reporting threshold. A seller with £900 on Vinted and £900 on eBay sits under the per-platform reporting threshold on both. But HMRC receives both reports, combines them, and sees £1,800 of combined income against which no Self Assessment return has been filed.

Trading Allowance or Actual Expenses Across Multiple Platforms

The decision between the trading allowance and actual expenses works the same way for multi-platform sellers as for single-platform sellers, but the inputs are combined.

You claim the trading allowance (£1,000) against your total combined gross income across all platforms. You claim actual expenses, everything you spent on stock, postage, packaging, platform fees and business mileage, against the same combined gross income. The lower taxable profit after either method is the one worth claiming.

For most multi-platform sellers with meaningful combined income, actual expenses tend to produce a better result. The more platforms you sell on, the higher your fee costs tend to be, and fee costs are legitimate deductible expenses. A seller with £1,800 of combined gross income and £600 of combined expenses has a taxable profit of £1,200 under actual expenses versus £800 under the trading allowance. In this case the trading allowance wins. Adjust the figures slightly and it goes the other way. The calculator above shows which option is better for your specific numbers.

Record Keeping Across Multiple Platforms

The practical challenge for multi-platform sellers is keeping a combined record that makes the annual gross income calculation straightforward. Each platform provides a transaction report or sales history. The discipline is downloading and combining them at least quarterly rather than trying to reconstruct the full year from scratch in January.

Our Vinted tax guide covers how to find and read your Vinted sales data. The eBay transaction report, which shows gross sale prices alongside fees, is the starting point for eBay income. For all platforms, the figure you want is the pre-fee sale price, not the net payout.

The UK Online Seller Tax Template handles this. The expenses tab is set up to log income fro any source, not just a single platform, and the summary tab combines everything into a single gross income figure, compares trading allowance versus actual expenses automatically, and shows your overall tax position for the year.
