TikTok Shop UK: Tax and VAT for Sellers and Affiliates

TikTok Shop income is taxable UK trading income whether you sell your own products or earn affiliate commission. Income Tax and Self Assessment work the same way for both, but sellers have stock, returns and a real VAT question, while affiliates have fewer costs and a VAT question that turns on who is paying you. This guide walks through both, with numbers, and is honest about the parts where the sources do not agree.

Sellers or affiliates: what is the difference for tax?

On TikTok Shop UK you are usually one of two things, and some creators are both.

• Seller: you list and sell your own products (or products you buy in) to customers. You earn sales income and carry costs of goods, postage, packaging, fees and returns.
• Affiliate: you promote other sellers' products through your videos and LIVEs and earn a commission on qualifying orders. TikTok's UK seller help describes commission as revenue less refunds, multiplied by the commission rate, paid only after the order is settled.

Both start from the same tax position: profits are taxable income. They diverge on costs and on VAT. If you also take sponsored posts or LIVE gifts, those add to the same pot; the basics are in our guide to tax on TikTok Creator Rewards income.

How do Income Tax and Self Assessment work for TikTok Shop?

If your gross trading income for the tax year, from TikTok Shop and everything else you do on a self-employed basis, is £1,000 or less, you normally do not need to register or report it. GOV.UK asks you to keep records regardless. Over £1,000 you register for Self Assessment, by 5 October after the tax year in which you went over, then file online and pay by 31 January.

On the return you can deduct either the £1,000 trading allowance or your actual allowable expenses, whichever gives the lower profit, but not both. Sellers with stock almost always claim expenses. Affiliates with tiny costs may prefer the allowance.

The £1,000 is a test on gross income before costs. A seller with £1,200 of sales and £1,500 of costs still has gross income over £1,000, so they register and can claim a loss.

What can sellers and affiliates deduct?

Only costs wholly and exclusively for the business, and only the business share of mixed-use items. GOV.UK confirms you can claim the business portion of things like phone bills and a proportion of household costs if you work from home. See our list of tax-deductible expenses for creators for the full picture.

How is a seller's profit worked out?

Sales income minus refunds, minus the costs of earning it. That is trading profit, and it is what you are taxed on. Two habits matter most.

Returns and refunds

Refunded orders reduce your income. Reconcile the shop's sales report to your payouts each month, because payouts arrive net of fees, refunds and adjustments and the difference is your cost or lost income, not a mystery.

Stock and cost of goods

Buying stock is not the same as spending profit. Track what you bought, what you sold and what is left. GOV.UK says cash basis is the default for the self-employed from 2024/25, which broadly means recording money when it is received or paid, but how you deal with unsold stock at the year end can depend on your circumstances, so ask us if you hold significant stock.

Do I need to register for VAT on TikTok Shop sales?

You must register if your VAT-taxable turnover goes over £90,000 in any rolling 12-month period, or if you expect it to go over £90,000 within the next 30 days alone. GOV.UK says you have 30 days from the end of the month you crossed the threshold, with registration effective from the first day of the second month after. Voluntary registration below £90,000 is allowed. Late registration means paying VAT on sales since you should have registered.

What counts as taxable turnover for a seller?

Sales of goods to UK customers are the core of it. Turnover generally means the value of what you sell, before deducting costs, so a growing shop can pass £90,000 while profit is a fraction of that. Some products are zero-rated or exempt, which affects your position. Our VAT registration guide has the full rules.

Is VAT registration worth it below the threshold?

Sometimes. Registering lets you reclaim VAT on business purchases, but you must charge VAT on sales, which may cut your margin or raise prices.

Is affiliate commission subject to VAT?

Here we have to be honest: this is the area where the sources we reviewed conflict, and we would rather tell you than pretend to certainty. Commission is a payment for a service you supply. Whether that service is supplied to a UK business, to TikTok, or to an overseas entity, and so where it is treated as supplied, depends on who your contract is really with and where that party belongs. Your creator terms and payout notices, not the app screen, tell you who that is.

• Commission paid by a UK business can count as VAT-taxable turnover.
• Commission paid by an overseas business may be outside the scope of UK VAT, though it can still matter for reporting.
• If your total taxable turnover including commission is far under £90,000, the question is academic for now.

Treat this as a point to confirm with a specialist if you are within striking distance of the threshold, or if affiliate commission is your main income.

Does TikTok Shop collect VAT for me?

Partly, and mainly for overseas sellers. GOV.UK's marketplace guidance says an online marketplace can become liable for VAT on certain sales, chiefly low-value goods of £135 or less sent from outside the UK to UK customers. For sellers established in the UK, the guidance we reviewed says traditional VAT rules apply and you stay responsible for your own VAT obligations. So do not assume the platform handles your VAT because it processes the payment.

Whether TikTok Shop counts as a marketplace for a particular sale depends on how it sets terms and handles payment, which is why we point you to the GOV.UK pages and your seller agreement rather than promising an answer. Overseas sellers shipping to UK customers face customs and VAT rules on top, so take specialist advice.

What records and digital duties should I expect?

• Monthly commission and settlement statements, matched to the money in your bank account.
• Sales, returns and refunds reports for sellers.
• Receipts for stock, samples, packaging, software and kit.
• A note of which business paid each commission and where it is based.

GOV.UK says self-employed records must be kept for 5 years after the 31 January deadline. On digital duties, Making Tax Digital for Income Tax became mandatory from 6 April 2026 for qualifying self-employment income over £50,000 (based on 2024/25). The threshold drops to £30,000 from 6 April 2027 and £20,000 from 6 April 2028. Check GOV.UK for the exact measure, then see our bookkeeping service if you want help with it. Our accountants for TikTok creators page covers how we work.

Common mistakes and a quick checklist

• Treating a payout as profit. Payouts are net of fees and refunds; profit is after stock and other costs.
• Watching the tax year for VAT. The test is any rolling 12 months.
• Assuming TikTok handles VAT. UK-established sellers stay responsible for their own.
• Deducting samples you keep. Business use only.
• Mixing allowance and expenses. One or the other.
• Forgetting non-Shop income. Brand deals and LIVE gifts count too.

1. Total this year's gross Shop income, plus everything else self-employed.
2. Diarise 5 October and 31 January if you are over £1,000.
3. Reconcile the Shop reports to your bank each month.
4. Track your rolling 12-month turnover against £90,000.
5. Note who pays each commission and where they are based.
