TikTok Shop VAT threshold: it's GMV, not your payout

If you sell on TikTok Shop, the single most expensive mistake you can make with VAT is counting the wrong number.

The figure that matters for the VAT threshold is your gross sales, what TikTok calls Gross Merchandise Value (GMV). It is not the money that actually lands in your bank after TikTok has taken its commission, affiliate fees and refunds.

We see this trip up sellers constantly. They look at their payout, see it is comfortably under £90,000, and assume they are nowhere near needing to register. Meanwhile their gross sales sailed past the threshold months ago, and a late-registration penalty is quietly building.

This guide explains exactly which number HMRC cares about, how to track it, and what happens at the point you cross the line. It is written for UK-based TikTok Shop sellers. If TikTok is currently handling VAT on some of your orders, we cover that too.

What is the TikTok Shop VAT threshold?

The TikTok Shop VAT threshold is £90,000 of taxable turnover (your gross sales) in any rolling 12-month period. Cross it and you must register for VAT. This is just the standard UK VAT registration threshold, which has been £90,000 since 1 April 2024, applied to your TikTok sales plus any other taxable sales you make.

There is no special, higher threshold for online sellers and no separate allowance for TikTok. The same rule that applies to a high street shop applies to your TikTok Shop.

Two things make this threshold easy to get wrong on TikTok specifically:

• It is measured on a rolling 12-month basis, not your tax year or calendar year. Every month you add the latest month and drop the one that fell off the back. So you can cross it mid-year without a fixed "reset" date warning you.
• The turnover you count is your gross sales (GMV), not the net amount TikTok pays out to you.

The second point is where most of the money goes wrong, so let's deal with it head on.

Why GMV, not your payout, is the number that counts

VAT registration is based on your "taxable turnover", which is the total value of everything you sell that is not exempt or outside the scope of VAT. For a typical TikTok Shop selling physical goods at the standard 20% rate, that means the full price the customer paid for your products.

TikTok does not pay you that full price. By the time the money reaches your bank, it has been reduced by:

• TikTok's platform commission
• Affiliate and creator commission on sales driven through the affiliate programme
• Transaction or payment processing fees
• Refunds and adjustments

Those deductions are TikTok's charges to you and refunds to customers. They do not reduce your taxable turnover. HMRC looks at the value of the sale you made to the customer, not the slice you were left with after the platform took its cut.

So if a customer pays £30 for your product and TikTok pays you £22 after fees, your taxable turnover from that sale is £30, not £22. Multiply that gap across thousands of orders and the difference between your GMV and your payout can easily be tens of thousands of pounds a year.

That is exactly the gap that pushes sellers over £90,000 without realising it.

In practice: the mistake we most often see is a seller using their bank statements or their TikTok payout reports to track turnover. Use your gross sales / GMV figure from TikTok's seller reporting instead. That is the number HMRC will measure you against.

Illustrative example: payout looks safe, GMV does not

Illustrative example. Maya runs a UK-based TikTok Shop selling phone accessories. Her average month looks like this:

Looking at her bank, Maya sees roughly £6,474 a month, about £77,688 over twelve months. That feels safely under £90,000, so she assumes she does not need to register.

But the number HMRC measures is her gross sales: £8,200 a month. Over a rolling 12 months that is £98,400, which is over the £90,000 threshold.

Maya should have been watching her GMV. On these figures she crossed £90,000 part way through the year and a VAT registration obligation was triggered. The fees and refunds she subtracted are irrelevant to the threshold test.

(Figures are illustrative and rounded. Your own commission and affiliate rates will differ, so always check your actual TikTok gross sales report.)

If you want help working out your real numbers, our accounting service for TikTok creators and sellers is built around exactly this kind of platform reporting.

When exactly do you have to register?

There are two separate tests for compulsory VAT registration, and you only need to fail one of them.

1. The backward-looking (rolling 12-month) test. At the end of every month, check your total taxable turnover for the previous 12 months. If it has gone over £90,000, you must register. You have until 30 days after the end of the month in which you went over, and your registration takes effect from the first day of the second month after you crossed the threshold.

So if your rolling total tips over £90,000 at the end of June, you must register by 30 July, and you are VAT registered from 1 August.

2. The forward-looking (next 30 days) test. If at any point you expect your taxable turnover to go over £90,000 in the next 30 days alone, you must register by the end of that 30-day period, and you are registered from the date you realised. A viral video that you reasonably expect to drive over £90,000 of sales in a month could trigger this test on its own.

Miss the deadline and HMRC can charge a failure-to-notify penalty, plus you will still owe the VAT on sales you made after you should have registered, even though you did not charge it to customers at the time. That last point is the painful one: the VAT comes out of margin you have already spent.

This is why tracking GMV monthly matters so much. By the time a late registration is discovered, the bill is backdated.

Does TikTok collect the VAT for me?

Sometimes, but probably not in the way you are hoping if you are a UK seller.

UK VAT rules make the online marketplace the "deemed supplier" (so TikTok charges and accounts for the VAT) only in specific overseas-seller situations:

• Goods located outside the UK at the point of sale, sold to a UK consumer, where the consignment is worth £135 or less. Here TikTok charges UK VAT at the checkout and pays it to HMRC.
• Goods already in the UK but sold by an overseas seller (a business not established in the UK). Here TikTok is treated as the supplier to the customer and accounts for the VAT.

If you are a UK-established seller holding your own stock in the UK, neither of those applies to you. You are responsible for your own VAT. That means you, not TikTok, must:

• monitor your GMV against the £90,000 threshold,
• register when you cross it,
• account for the VAT within your selling prices, and
• report it on your own VAT returns.

In short: for a normal UK TikTok seller, TikTok is not your VAT safety net. The obligation sits with you.

One important catch for overseas sellers: if you are not established in the UK and you hold stock here, there is no registration threshold at all. You must register for UK VAT as soon as you start making taxable sales of goods stored in the UK.

What changes once you are VAT registered?

Once you are registered, on standard-rated goods you are effectively handing 1/6th of each VAT-inclusive sale to HMRC. On a £30 standard-rated sale, £5 is VAT and £25 is your net sale.

Practically, that means:

• Your prices already include VAT. TikTok Shop prices are shown to consumers inclusive of VAT, so registering does not let you bolt 20% on top. Unless you raise prices, the VAT comes out of your existing margin, which is why pricing needs a rethink at registration.
• You can reclaim input VAT on your costs, such as stock, packaging, ads and software, where you hold a valid VAT invoice.
• You file VAT returns, usually quarterly, and pay the difference between the VAT in your sales and the VAT you reclaim.
• You must follow Making Tax Digital for VAT. All VAT-registered businesses have to keep digital records and file returns using MTD-compatible software. There is no longer a turnover exemption from MTD for VAT.

If you issue VAT invoices to business customers, a full VAT invoice has to show your VAT registration number, the VAT rate and the VAT shown separately from the net price.

Getting your VAT return boxes right from the first quarter avoids corrections later. If quarterly returns are not how you want to spend your evenings, this is where our tax advisory and VAT support comes in.

Should TikTok Shop sellers use the Flat Rate Scheme?

The Flat Rate Scheme (FRS) lets smaller businesses pay a fixed percentage of their VAT-inclusive turnover to HMRC instead of working out VAT on every sale and purchase. You can join if your expected VAT-taxable turnover is £150,000 or less (excluding VAT) in the next 12 months.

It can simplify your admin, and there is a 1% discount in your first year of VAT registration. But there is a catch that hits a lot of ecommerce sellers.

If you are a "limited cost business", meaning your spend on goods is less than either 2% of your turnover or £1,000 a year, you must use the higher flat rate of 16.5%. Many TikTok sellers who dropship or buy very little physical stock fall into this category, and 16.5% of gross turnover often works out worse than the standard method once you account for the input VAT you would otherwise reclaim.

So the FRS is not an automatic win for TikTok sellers. It depends on your margins, your stock spend and how much input VAT you have. It is worth modelling both methods before you choose.

What about the digital platform reporting rules?

Separately from VAT, platforms like TikTok now have to report seller information to HMRC under the UK's reporting rules for digital platforms (sometimes called the model reporting rules, MRDP), which took effect from 1 January 2024 with the first reports due in early 2025.

In plain terms, TikTok reports details of what it has paid you to HMRC, and gives you a copy of the same information. There is a small-seller exemption: a seller is generally not reportable for goods if they made fewer than 30 sales and received no more than around €2,000 (roughly £1,700) in the reportable period.

This is not a new tax. It does not change your VAT threshold or your income tax position. What it does mean is that HMRC can now see your platform earnings directly, so making sure your declared turnover matches what TikTok reports is more important than ever. The days of platform income being invisible are over.
