TikTok Shop sellers are the fastest-growing category of new UK businesses HMRC is paying attention to. The platform is new enough that many sellers assume the tax rules are somehow different or delayed. They are not. HMRC's position on TikTok Shop income is exactly the same as for any other trading income: if you earn it, you declare it and pay tax on it.
The £1,000 Trading Allowance
Every UK individual gets a £1,000 trading allowance per tax year. If your total self-employment income (including TikTok Shop) is below £1,000, you don't need to declare it. Once it exceeds £1,000, you must register for self-assessment by 5 October following the end of the tax year in which you first exceeded the threshold.
Income Tax on TikTok Shop Sales
TikTok Shop sales income is trading income for income tax purposes. It's taxed after deduction of allowable business expenses at your marginal rate.
- 0% on the first £12,570 of total income (personal allowance)
- 20% on income between £12,571 and £50,270 (basic rate)
- 40% on income between £50,271 and £125,140 (higher rate)
- 45% on income above £125,140 (additional rate)
Allowable expenses include cost of goods sold, packaging and shipping, TikTok platform fees, TikTok Ads spend, affiliate commissions paid to creators, photography and video production costs, and a proportion of your broadband and phone bill.
The VAT Threshold: The Biggest TikTok Shop Risk
The most dangerous tax situation for TikTok Shop sellers is reaching the £90,000 VAT registration threshold faster than expected. A viral product can push a seller past £90,000 in rolling 12-month turnover in a single month — and once crossed, the 30-day notification obligation starts immediately.
TikTok Shop does not automatically collect and remit UK VAT on your behalf for domestic UK-to-UK sales. If you were required to be VAT registered and weren't, the liability is yours — even if you never charged your customers.
Affiliate Commission Income: TikTok Creator Taxes
TikTok's affiliate programme pays creators a commission for every sale they generate. This commission income is taxable trading income. HMRC taxes you on your gross commission, not the net amount received after TikTok's cut. If you're a VAT-registered creator receiving significant commission income, you may need to self-account for VAT on commission earnings.
Does TikTok Shop Report to HMRC?
Yes. From January 2024, digital platforms including TikTok Shop are required to report seller data to HMRC under OECD rules adopted into UK law — including total earnings paid through the platform per calendar year. HMRC cross-references this against self-assessment returns. The penalties for deliberate non-disclosure are up to 100% of the unpaid tax.
