TikTok affiliate accountants for UK creators.
Yes, TikTok affiliate commission is taxable. Once your commission, the products you get for promoting and any other trading income pass £1,000 in a tax year, HMRC needs to hear about it.
Commission you earn promoting other people’s products is trading income, the same as any self-employed work. HM Revenue and Customs (HMRC) counts the products you receive for promoting them as income too, at what they would have cost you. Add it all up with any other trading income, such as TikTok Shop sales or freelance work, and if the total is more than £1,000 for the tax year, you register for Self Assessment by 5 October after that tax year ends. We work out the total, keep the records, choose between your real expenses and the £1,000 allowance, check whether your commission counts for value added tax (VAT), and file your return. Fixed monthly fees from £129 plus VAT, from a CIMA-regulated firm.
What makes affiliate tax different?
- Free products are income too
- HMRC’s guidance for online content creators says gifts and services you receive for promoting products count as income, valued at what they would have cost you. A creator with modest commission and a steady stream of kept products can pass £1,000 without noticing.
- The £1,000 is gross, not profit
- The trading allowance test uses your gross income from all your trading together: commission, kept products, any TikTok Shop sales of your own and other freelance work. Over £1,000, a sole trader either deducts the £1,000 allowance or their actual expenses, not both, so it pays to know which is bigger. From the 2027/28 tax year the allowance is due to rise to £3,000, under legislation announced on 28 October 2026.
- VAT depends on who your customer is
- Commission is payment for a service, and the VAT question turns on the business you supply that service to, usually the company named in your affiliate terms, and where it belongs. If it belongs outside the UK, the commission is usually outside the scope of UK VAT and does not count towards the £90,000 registration threshold. You must register if your taxable turnover across all your business goes over £90,000 in any rolling 12 months, not your tax year, or if you expect it to go over £90,000 in the next 30 days alone. We read your affiliate terms and check this before you get near it.
- Growing fast changes the structure question
- Affiliate income can jump from pocket money to a full salary in a season. Once profits are steady and high, a limited company can sometimes leave you with more after tax. We model it on your actual figures before recommending it.
Commission, products and the £1,000 allowance.
One tax year for an illustrative affiliate who promotes beauty products. The figures are made up to show the mechanics; your own commission statements will differ.
- Affiliate commission received
- £4,200
- Products kept, at what they would have cost
- £700
- Gross trading income
- £4,900
- Actual expenses: ring light, share of phone and data
- £450
- Trading allowance instead
- £1,000
- Taxable profit using the allowance
- £3,900
Gross income is over £1,000, so this creator registers for Self Assessment by 5 October after the tax year ends. The £1,000 allowance beats £450 of real expenses, so the allowance is used and the expenses are not claimed as well. If expenses had been £1,600, claiming them would have given the lower profit. Income Tax then depends on your total taxable income, including any job. Class 4 National Insurance is worked out on the trading profit itself.
Where do TikTok affiliates usually go wrong?
Most of these come from income that never arrives as cash, or from adding up the wrong things.
- Ignoring the products
- Counting only the commission that lands in your bank leaves out the products you received for promoting, which HMRC treats as income at what they would have cost.
- Assuming a job covers it
- Having tax deducted from your salary through Pay As You Earn (PAYE) does not automatically cover your commission or remove the need to tell HMRC about it, and the deadline still applies.
- Claiming the allowance and expenses
- Over £1,000 it is one or the other. Claim both and your profit is understated.
- Mixing up selling and promoting
- If you sell your own stock on TikTok Shop as well, that is a second kind of income with its own records and its own VAT position.
- Registering late
- Miss the 5 October registration deadline and you can owe a penalty on top of the tax. Telling HMRC early, before it asks, is almost always the better position.

TikTok affiliate tax questions, answered
It is taxable income. Commission for promoting products is trading income, and HMRC adds it to any other trading income you have, such as TikTok Shop sales or freelance work. If the gross total is more than £1,000 in the tax year you need to tell HMRC through Self Assessment. Whether you then owe tax depends on your profit and your other income.
Products you are given to keep for promoting them count as income, valued at what they would have cost you, according to HMRC’s guidance for online content creators. Stock you have to send back, or samples you send out yourself, follow different rules.
If your gross trading income is more than £1,000 for a tax year, register for Self Assessment by 5 October after that tax year ends. For 2025/26 that was 5 October 2026; for 2026/27 it is 5 October 2027. From 2027/28 the £1,000 is due to rise to £3,000.
Not both. Once your gross trading income is over £1,000 you either deduct the £1,000 allowance or your actual allowable expenses. If your expenses are more than £1,000, claiming them gives you the lower profit.
You only charge VAT once you are VAT registered. Before that, the question is whether your commission counts towards the £90,000 registration threshold, which applies when your taxable turnover goes over £90,000 in any rolling 12 months, or is expected to in the next 30 days alone. That depends on the business you supply the promotion service to, usually the company named in your affiliate terms. If it belongs outside the UK, the commission is usually outside the scope of UK VAT and does not count. We read your terms and check.
Not always. If your gross trading income, including commission and products you received for promoting, is well under £1,000 a year, you may not need to tell HMRC about it. Once you are registering for Self Assessment, have several income streams or are near the VAT threshold, an accountant can save you time and help avoid mistakes.
