TikTok Shop affiliate commission is taxable UK trading income. You pay Income Tax and Class 4 NI on profit after allowable costs, and register for Self Assessment once gross income is over £1,000. Whether commission counts towards the £90,000 VAT threshold depends on who is paying you, so check before you assume it does not.

Do TikTok Shop affiliates need an accountant?
Affiliates promote other sellers' products through videos and LIVEs and earn commission when an order goes through. It is easy to treat that as pocket money while it is small, then be surprised when the monthly payouts add up. Over a tax year they can pass the £1,000 trading allowance well before you feel like you are running a business.
The tax position is simple in principle and fiddly in practice: payouts arrive after the order settles, can be reduced by returns, and sit alongside creator rewards, LIVE gifts and brand deals. We bring it all together on one return.
How TikTok Shop affiliate income is taxed
- Commission is trading income: it goes on your Self Assessment return as self-employed income, whether it is your main income or a side hustle.
- The £1,000 test uses gross income: if your combined self-employed income before costs is over £1,000, you register. You then take either the £1,000 allowance or your actual costs, not both (GOV.UK).
- Returns reduce income: commission on refunded orders generally does not stay with you, so reconcile each payout to its orders rather than counting a gross figure.
- Mixed income is added together: LIVE gifts, Creator Rewards and brand deals sit on the same return. See our guide to TikTok Creator Rewards tax.
Affiliate or seller: which are you?
| Affiliate | Seller | |
|---|---|---|
| What you do | Promote others' products for commission | Sell your own or bought-in products |
| Main costs | Samples, kit, software, phone share | Stock, fees, postage, packaging, returns |
| Stock records | Rarely relevant | Essential |
| VAT question | Depends on who pays the commission | UK sales count towards the £90,000 threshold |
If you do both, the income is added together. Our full guide, TikTok Shop UK tax and VAT for sellers and affiliates, covers the seller side and the rules in more depth.
What affiliates can claim
Camera or phone, lighting, tripod and microphone, with a business-use share where kit is also personal
Products bought to review are deductible in principle, but not ones you keep for private use
Editing, scheduling and analytics tools used for the work
Paid boosts or ads that you buy to grow your affiliate videos
Products a seller sends you for free are a separate issue, covered in our guide to gifted products. For the wider list, see tax-deductible expenses for creators and GOV.UK's guidance on allowable expenses.
Is affiliate commission subject to VAT?
VAT registration is compulsory if your taxable turnover goes over £90,000 in any rolling 12 months, or you expect it to within the next 30 days (GOV.UK: when to register for VAT). Most affiliates are below that, so VAT is academic for now.
Where it gets uncertain is whether commission counts as UK-taxable turnover. That depends on who your contract is really with and where they belong, which your creator terms and payout notices show rather than the app screen. We would rather say that plainly than pretend to a simple rule. If commission is your main income and you are heading towards the threshold, talk to us early. Our VAT service can review it.
What an affiliate might pay: a worked example
A UK TikTok Shop affiliate earns £27,500 of commission in 2026/27 and spends £3,100 on kit, samples and software.
| Commission received | £27,500 |
| Allowable costs | -£3,100 |
| Profit | £24,400 |
| Income Tax (20% above £12,570) | £2,366.00 |
| Class 4 NI (6% above £12,570) | £709.80 |
| Total tax and NI | £3,075.80 |
That is about 12.6% of profit. Illustration only, at 2026/27 rates for England, assuming no other income, no student loan and no payments on account. Your figures will differ.
