VAT for online sellers has become a far less private matter than it used to be. Say you sell handmade jewellery on Etsy, vintage finds on eBay and stock clear-outs on Vinted: every sale you make in the course of a business counts towards the same threshold, and the platforms themselves are now telling HMRC what you earn.
For years, many women running craft, vintage and handmade businesses treated each marketplace as its own little world. Etsy income felt separate from eBay income; both felt separate from a Facebook Marketplace sale or a Vinted wardrobe clear-out. That separation was never accurate for VAT purposes, and since January 2024 it has become much harder to overlook. This guide sets out exactly what UK sellers trading across multiple platforms need to understand. It does not cover the registration process itself, or the pros and cons of registering early.
VAT for online sellers: why every platform counts towards one threshold
The VAT registration threshold in the UK has stood at £90,000 of taxable turnover since April 2024, measured over any rolling 12-month period. That figure applies to your business as a whole, not to any single shop front. If you sell on Etsy, eBay, Amazon and Vinted, HMRC adds up the gross taxable turnover from all of them.
This is the detail that catches people out. A seller might think of her Etsy shop as “the real business”, while her eBay account feels like a side project for offloading stock or secondhand items. HMRC does not see it that way. Taxable turnover means the total value of everything you sell that is not exempt from VAT, counted across every channel combined: your own website, a market stall, Amazon Handmade, and a Vinted account you use to sell things you have made rather than possessions you have simply outgrown. Selling your own unwanted possessions in a genuine personal clear-out is not a business activity, and those sales do not count towards the threshold at all.
This matters enormously for online sellers who diversify across platforms deliberately, often as a defence against any single marketplace changing its fees or algorithm. Spreading sales across four or five sites is sound business strategy; it does nothing, however, to spread your VAT liability. HMRC watches your combined gross taxable turnover, and once that crosses £90,000 in any rolling 12-month period you must register, no matter how thinly you split the income between platforms.
What changed in January 2024: platforms now report your income to HMRC
The biggest shift for online sellers in recent years did not come from a Budget announcement but from a quieter, more structural change. From 1 January 2024, digital platform operators, meaning the websites and apps that let people sell goods and services, have had to collect and check seller details, then report them to HMRC. The rules are based on the OECD’s Model Reporting Rules for Digital Platforms.
Platforms including Etsy, eBay, Amazon and Vinted now report seller information annually, with the deadline for each calendar year’s data falling on 31 January the following year. The first reports, covering sales made in 2024, were due by 31 January 2025. This closes what might be called the invisible side-income era. Previously, many casual and semi-casual sellers assumed modest, irregular online income would escape HMRC’s attention unless they volunteered it. That assumption no longer holds: the platform does the reporting on your behalf, whether you mention it on a tax return or not.
It is worth being clear about what this reporting regime is and is not. It does not create new tax obligations, and it does not mean every seller suddenly owes VAT or Income Tax they did not owe before. What it does is remove the gap between what a seller declares and what HMRC can see independently. If your declared turnover and the platform’s reported figures do not line up, HMRC will see it. That mismatch is now visible by design, not by chance.
What you must tell Etsy, eBay, Amazon and Vinted
To comply with these rules, marketplaces must collect specific information from every seller, and most now ask for it as a condition of keeping your account active. As an individual seller, you will typically need to provide your full name, home address and date of birth, plus a tax identification number, which for UK residents is usually your National Insurance number.
If you trade as a business entity rather than an individual, the details change. The platform needs your legal business name, main business address and a tax identification number appropriate to your structure: your company registration number for a UK limited company, or the partnership’s Unique Taxpayer Reference for a partnership. If you are still deciding which structure fits your business, our guide to choosing between sole trader and limited company sets out the trade-offs.
Once a platform has reported your information, it must also give you a copy of what it has sent to HMRC, so you can check it against your own records and use it when completing your tax return. One thing to expect: the figure on that report reflects your gross sales, before the platform’s fees and commission come out of your payouts, so it will almost always look higher than the amount that actually reached your bank account. That gap is normal, but your own records should be able to reconcile the two. If a platform you sell on regularly has never sent you this document, check your account settings or messages; the information is there for your benefit as much as HMRC’s.
The casual seller exception, and why it doesn’t cover services
There is a narrow carve-out built into this reporting regime, aimed squarely at people doing genuine one-off clear-outs rather than running a trading business. Under HMRC’s rules, platforms do not need to report sellers who stay under both limits in a calendar year: total takings of €2,000 or less (roughly £1,700) and fewer than 30 sales of goods.
In practice, this exception exists to protect someone selling a handful of unwanted items on Vinted or eBay, who could otherwise be swept into a reporting system designed for sellers running an actual trade. If you sold fifteen items of old clothing for a total of £300 last year, this exception was written for you.
This is where many sellers misread the rules, so it is worth being precise. The exception applies only to goods, and only below both thresholds at once: the euro value and the number of sales. It does not apply to services, transport rental or property rental under any circumstances. If you offer bespoke commissions, pattern-making services or alterations, the exception never applies; the same goes for renting out equipment through an online platform. Every one of those transactions is reportable, however small the amount. A woman offering custom portrait commissions through an online platform cannot rely on the casual seller exception at all, even if she only does three commissions a year.
Remember too that this reporting exception has nothing to do with the VAT registration threshold itself. A seller could fall under the reporting exception yet still need to include her Vinted sales in her taxable turnover calculation, if those sales are part of an organised trading activity rather than a genuine personal clear-out. The two rules sit alongside each other rather than replacing one another.
VAT for online sellers once you’re registered: the marketplace checklist
Once you cross the threshold and register, VAT for online sellers becomes an operational matter that touches every platform you use, not just your main accounting system. The first practical step is to give your VAT registration number to every marketplace where you sell, not only the one where most of your turnover sits.
This matters more than it might seem. Marketplaces cross-check seller accounts against HMRC’s VAT number checker, and gov.uk guidance is explicit that a marketplace may remove you from its platform if it cannot match your trading account name against the name on your VAT registration. Say Etsy lists your shop as “Willow & Thread Designs” but your VAT registration sits under your personal name, with no matching trading name on record: that mismatch can cause problems, up to removal while you sort out the discrepancy.
The practical fix is straightforward, if sometimes fiddly. Register your trading name consistently, using the same business name across HMRC records and every platform account, and update each marketplace’s seller settings as soon as your VAT registration comes through. Doing this across four or five platforms takes an afternoon; leaving it undone risks an account suspension at a busy trading time, which costs far more than the admin.
Once registered, you also need to charge VAT correctly on sales made through marketplaces and account for VAT on the fees those platforms charge you. Your VAT return must reflect marketplace sales alongside sales from your own website or in-person trading. None of this changes which VAT accounting scheme suits you best; that is a separate decision. But your bookkeeping must capture gross sales, platform fees and VAT consistently across every channel, not just the largest one.
Overseas sellers and Northern Ireland: the wider picture
It helps to see how UK-based sellers fit into the bigger picture, because the rules for overseas sellers work quite differently, and the contrast clarifies why UK sellers are treated the way they are. Since 1 January 2021, special rules have applied where overseas businesses sell goods to UK consumers through an online marketplace. Where goods are outside the UK at the point of sale and the consignment is worth £135 or less, the law treats the sale as though the marketplace itself made it: the platform, not the overseas seller, becomes responsible for accounting for the VAT.
This explains the contrast. A UK seller handmaking items at home faces different obligations to an overseas seller shipping low-value parcels into the UK. As a UK-based seller, the VAT responsibility sits with you directly once you cross the threshold; the platform does not absorb it on your behalf.
Sellers based in Northern Ireland face an extra layer if they sell to customers across the EU. Since July 2021, Northern Ireland sellers making distance sales of goods to EU consumers have faced a further test: once total EU distance sales exceed €10,000 in a year, which gov.uk sets at £8,818, you must register for VAT in the relevant EU country, or use the EU’s One Stop Shop scheme to account for the VAT through a single return. This threshold applies across all EU sales combined, much as the UK threshold applies across all UK marketplaces combined. If you run a vintage homeware business from Belfast, shipping regularly to customers in Ireland, France and Germany, track that EU total separately from your UK figures; crossing it triggers a registration obligation in the EU rather than in the UK.
Keeping on top of VAT across multiple platforms
The practical upshot for anyone running a craft, vintage, handmade or product business across several marketplaces is simple. Add up your gross taxable turnover across every platform, not just your biggest one, and check that combined figure against the £90,000 threshold monthly rather than annually. The test is a rolling 12-month one, not a fixed tax-year calculation.
Keep a simple spreadsheet that totals Etsy, eBay, Amazon, Vinted and any other channel side by side. It takes ten minutes a month, and you will see the threshold approaching well before it becomes a surprise. The digital platform reporting rules introduced from January 2024 mean HMRC already has a version of this picture; having your own version means there are no surprises on your end either.
If you are weighing up which platforms suit a growing handmade or vintage business, start with the wider picture.
