Your TikTok payout lands in dollars, but your tax return is in pounds. HMRC does not care what currency you were paid in — every figure on your Self Assessment must be in sterling, converted at a reasonable exchange rate. Get the conversion method wrong and your turnover, your VAT position and your profit can all be off by hundreds of pounds.
If you sell on TikTok Shop, earn affiliate commission, or take creator-fund or marketplace payments from a US or overseas TikTok entity, there is a good chance some of your money arrives in USD or another foreign currency. This guide explains exactly how to record those payouts for the 2026/27 tax year: which rate to use, how to log income in sterling, what to do about foreign-exchange (FX) gains and losses, and how all of this interacts with the VAT place-of-supply rules for overseas commission.
The core rule: convert every payout to sterling
UK tax is computed in pounds sterling. When you receive income in a foreign currency, you must translate it into sterling using a “just and reasonable” exchange rate. HMRC does not force one single method on sole traders, but it does expect you to be consistent and to use a recognised, evidenced rate — not a number you made up.
In practice you have three sensible options, and you should pick one and stick to it for the whole tax year:
- HMRC monthly average rates. HMRC publishes monthly average exchange rates (and yearly averages) specifically for converting foreign income. These are the safest, simplest choice for most creators because they are official, free to access, and you only need to look up one rate per month.
- The spot rate on the day. The actual market rate on the date you became entitled to the income. This is more precise but more work, and you must keep a dated screenshot or record of each rate.
- The actual rate you got. If your bank or payment provider (Wise, PayPal, Payoneer, your high-street bank) converted the dollars to pounds and you can see the exact sterling figure that hit your account, that real converted amount is itself a perfectly good “just and reasonable” rate — and it has the advantage of matching your bank statement penny for penny.
For a typical TikTok creator, the cleanest approach is: record income at the HMRC monthly average rate, and use your provider's actual converted figure to track FX gains and losses (more on that below). If you keep all your money in a USD wallet and convert in lumps, the monthly-average method is your friend.
Which date do you use?
This matters because exchange rates move. The date you use depends on your accounting basis:
- Cash basis (which most sole-trader creators use, and which is now the default): you record income on the date the money is actually paid to you — the date TikTok releases the settlement to your wallet or bank, not the date you raised an invoice. Convert using the rate for that date or that month.
- Accruals (traditional) basis: you record income on the date you earned it / invoiced it, even if payment comes later. Convert at the rate for the invoice date.
Be consistent. If you use the HMRC monthly average, apply the rate for the month the payment (cash basis) or the invoice (accruals basis) falls in.
Worked example: a USD affiliate payout
Say you are Aisha, a UK-based TikTok creator on the cash basis. In June 2026 the US TikTok affiliate programme pays you $4,000 of commission into your Wise USD balance.
Assume the HMRC monthly average rate for June 2026 is 1.27 USD to the pound (you will use the actual published figure — this is illustrative).
- Income to record in your books: $4,000 ÷ 1.27 = £3,149.61.
- That £3,149.61 is your gross trading income for that payout. It goes into your turnover figure for the year.
Now suppose Aisha leaves the dollars sitting in her Wise account and converts them to sterling two months later, in August 2026, when the rate has moved to 1.24. She now actually receives:
- $4,000 ÷ 1.24 = £3,225.81 hitting her bank.
She recorded £3,149.61 as income but received £3,225.81 in cash. The £76.20 difference is an FX gain — covered next.
FX gains and losses: do they matter?
When you hold a foreign currency and the rate moves between the date you earned the income and the date you convert it, you make a foreign-exchange gain or loss on the currency itself. How you treat it depends on your structure:
- Sole trader on the cash basis: in practice this is the simplest case. If you record the income at the actual sterling you receive when it lands in your bank, there is no separate FX gain or loss to track — the conversion is baked in. If you record at the monthly-average rate and convert later at a different rate, the small difference is a trading FX gain or loss and is part of your trading profit. Keep it simple: most creators just record what they actually banked.
- Sole trader on accruals basis: you record income at the invoice-date rate, and any difference when cash arrives is a foreign-exchange movement that adjusts trading profit.
- Limited company: FX gains and losses on trading income and on currency balances are dealt with under the loan-relationship and forex rules and generally go through your profit and loss account, affecting your corporation-tax profit. If you trade through a company and hold significant USD balances, get this reviewed.
The headline for a typical creator: do not over-engineer this. Record the actual sterling that reaches your bank, keep the statements, and the FX movement looks after itself. The complications only really bite if you hold large foreign balances for long periods or trade through a company — one more reason to read up on the sole trader versus limited company decision before you scale.
How foreign payouts interact with the VAT threshold
This is where creators most often go wrong — and where converting to sterling actually changes your VAT exposure.
The VAT registration threshold is £90,000 of taxable turnover on a rolling 12-month basis (or if you expect to cross it in the next 30 days). It has been £90,000 since 1 April 2024. But not every pound of income counts toward that £90,000 — and your foreign-currency commission is a prime example.
For business-to-business services, the general place-of-supply rule says VAT is due where the customer belongs. So:
- Affiliate / marketing commission billed to an overseas business — for example a Chinese or US seller, or an overseas TikTok entity — is outside the scope of UK VAT. It does not count toward your £90,000 threshold, and you do not charge UK VAT on it.
- Commission from a UK-established business does count toward the threshold, and once you are registered it is standard-rated at 20%.
So when you convert that $4,000 US affiliate payout to £3,149.61, you record the sterling figure as income for income-tax purposes — but because the customer (the US TikTok entity) belongs overseas, that £3,149.61 sits outside the scope of UK VAT and is excluded from your rolling threshold test. We go deeper on this in our guide to tax on TikTok affiliate commission and our explainer on the TikTok Shop VAT threshold.
The practical upshot: a creator earning, say, £70,000 from a UK brand and £40,000 from a US affiliate programme has £110,000 of total income but only £70,000 counting toward VAT registration — so they are not required to register. Get the split wrong and you either register needlessly or miss a registration you genuinely needed.
Worked example: the threshold test with mixed currencies
Over a rolling 12 months, creator Tom has:
- UK brand-deal and UK affiliate income: £58,000 (counts toward the threshold).
- US TikTok affiliate commission, totalling $40,000, converted at HMRC monthly rates to roughly £31,500 (overseas customer → outside scope → does not count).
Tom's total income is about £89,500, which looks dangerously close to £90,000. But his VAT-relevant turnover is only £58,000, comfortably under the threshold. He does not need to register. If a single big UK brand campaign then pushed his UK income over £90,000, he would need to register at that point — the overseas commission still would not count.
One caveat specific to TikTok Shop sellers: where TikTok acts as the deemed supplier / online marketplace for certain overseas-seller goods and low-value imported consignments of £135 or less, TikTok itself accounts for the UK VAT on that sale. That changes who owes VAT on the goods, but it does not change how you convert and record your own foreign-currency payouts.
Record-keeping: what to actually save
HMRC cross-checks tax returns against the data platforms report under the OECD digital-platform reporting rules (what many people call DAC7). Since 1 January 2024, platforms such as TikTok Shop must collect and report seller income and identity details to HMRC each year — the figures for 2025 were reported by 31 January 2026. Those figures may well be in the currency TikTok paid you, so your sterling records need to reconcile back to them.
Keep, for every foreign payout:
- The TikTok settlement or affiliate statement showing the foreign-currency amount and the date.
- The exchange rate you used and its source (e.g. “HMRC monthly average, June 2026”).
- The sterling figure you recorded.
- Your bank/Wise/PayPal statement showing the actual converted amount received.
From 6 April 2026, Making Tax Digital for Income Tax (MTD for ITSA) is mandatory for sole traders and landlords whose qualifying income (gross turnover before expenses, assessed on the 2024/25 return) is over £50,000 — about 860,000 people in the first wave. That means digital records and quarterly updates through MTD-compatible software. The threshold drops to over £30,000 from April 2027 and over £20,000 from April 2028. If your converted sterling turnover puts you over those lines, your FX conversions need to live in software, not a shoebox.
Don't forget income tax and NIC on the sterling figure
Whatever currency you were paid in, the converted sterling profit is taxed under the normal rules for 2026/27:
- Trading allowance: £1,000 gross. Once your gross trading income exceeds £1,000 in a tax year, you must register for Self Assessment.
- Personal allowance: £12,570 (frozen). Income tax then 20% to £50,270, 40% to £125,140, 45% above.
- Class 4 NIC: 6% on profits between £12,570 and £50,270, then 2% above £50,270.
- Class 2 NIC: not compulsory; profits at or above the Small Profits Threshold of £7,105 give you a qualifying year for the State Pension with nothing to pay.
So Aisha's £3,149.61 USD commission is simply added to her other trading income, totted up in pounds, and taxed at her marginal rate. Before you do that, make sure you have claimed everything you can — see our rundown of allowable expenses for TikTok creators.

Frequently asked questions
Which exchange rate should I use for my TikTok USD payouts?
Any “just and reasonable” rate is acceptable, but pick one method and stick to it for the year. The easiest is HMRC's published monthly average rate. Alternatively, use the actual sterling figure your bank or payment provider gave you on conversion — that matches your bank statement exactly and is also acceptable to HMRC.
Does my US affiliate commission count toward the £90,000 VAT threshold?
No. Commission billed to an overseas business — such as a US or Chinese seller or an overseas TikTok entity — is outside the scope of UK VAT under the place-of-supply rules, because the customer belongs overseas. It does not count toward the £90,000 rolling threshold. Commission from a UK-established business does count and is standard-rated at 20% once you are registered.
Do I have to pay tax on the foreign-exchange gain when I convert dollars to pounds?
For a sole trader on the cash basis, the simplest approach is to record the actual sterling you receive when the money is converted, which builds the FX movement into your income with nothing extra to track. If you record income at the monthly-average rate and convert later at a different rate, the small difference is a trading FX gain or loss within your profit. Limited companies follow the separate forex and loan-relationship rules, so get larger foreign balances reviewed.
What records do I need to keep for foreign-currency TikTok income?
Keep the TikTok settlement or affiliate statement (foreign amount and date), the exchange rate you used and its source, the sterling figure you recorded, and the bank or wallet statement showing the actual amount received. HMRC cross-checks returns against the income platforms report under the digital-platform reporting rules, so your sterling records must reconcile back to the figures TikTok reports.
