Temu Sellers UK Tax Compliance Guide

Temu has become one of the fastest-growing marketplaces for UK side-hustlers and resellers, with thousands of sellers using the platform to earn extra income or build small eCommerce operations. As activity increases, HMRC has started paying closer attention to income generated through digital platforms, including Temu. This shift forms part of the Platform Reporting Rules (DAC7), which require online marketplaces to collect and share seller data with tax authorities.

From 2025 onwards, Temu will report UK seller earnings directly to HMRC, giving the tax authority full visibility of how much individuals make through the platform. For anyone selling regularly or earning more than a small casual amount, understanding Temu tax accounting and your overall tax position is now essential to avoid penalties or unexpected bills.

Are Temu sellers considered self-employed for tax purposes?

In most cases, if you are buying stock to resell on Temu with the intention of making a profit, HMRC will treat you as running a business as a self-employed sole trader, even if it starts as a small side hustle.

HMRC looks at a mix of factors–often called the “badges of trade”–to decide whether you are trading or just selling the odd personal item. These include things like how often you sell, whether you are aiming for profit, how organised your activity is, and whether you are holding stock in the same way as a normal retailer. You can see HMRC’s own summary of these indicators in its Business Income Manual on the badges of trade.

HMRC has also published a dedicated guide for people earning money through marketplaces and social media. It explains that income from selling goods online can be taxable where it goes beyond occasional sales of your own belongings and starts to look like a business. You can read this on GOV.UK under “Check if you need to tell HMRC about your income from online platforms”.

If your total trading income from Temu and any other self-employment is £1,000 or less in a tax year, it is usually covered by the trading allowance. In that case, you do not normally need to register for Self Assessment or tell HMRC about that income. Once your gross income from trading goes above £1,000, you must declare it, either using the trading allowance or by claiming your actual business expenses. This is set out in HMRC’s guidance on “Tax-free allowances on property and trading income” and is also reflected in more recent explanations from Low Incomes Tax Reform Group.

In practical terms, that means many Temu sellers will be treated as self-employed once they are regularly listing items, buying stock specifically to resell, or earning more than £1,000 a year in gross sales–and at that point, HMRC expects you to register, keep records, and report your profits.

How Temu Income Is Taxed in the UK

Once HMRC treats your Temu activity as trading, your profits are taxed in the same way as any other self-employed income.

You normally report Temu income through a Self Assessment tax return, using the self-employment pages. HMRC taxes your profit (income minus allowable business expenses), not just the total sales that hit your Temu account. You can find HMRC’s overview of Self Assessment for the self-employed on GOV.UK.

To simplify what this means in practice, here’s a quick breakdown:

Area	What it means for Temu sellers
Taxable figure	You are taxed on profit (sales minus allowable expenses), not on gross payouts.
Allowable expenses	You can usually claim stock costs, packaging, postage, software, transaction fees, part of home use, and marketing, as long as they are wholly and exclusively for the business.
National Insurance	Profits over certain thresholds trigger Class 2 (treated as paid or voluntary) and Class 4 NIC.
Record keeping	You must keep accurate records of sales, fees, refunds, and expenses for at least 6 years.
Making Tax Digital (MTD)	From April 2026, many sole traders will have to keep digital records and send quarterly updates to HMRC using approved software.

Revenue vs profit

Your revenue is the total Temu sales before any costs. Your profit is what is left after you deduct allowable expenses such as:

• Purchase cost of goods you resell
• Import duties and import VAT you cannot reclaim
• Packaging and postage
• Temu/platform fees and payment processing charges
• Accounting and bookkeeping software (for example, Xero)
• A reasonable share of home running costs if you work from home

HMRC sets out what counts as an allowable business expense in its guidance on expenses if you’re self-employed.

National Insurance for Temu sellers

If you are self-employed, you may also have to pay National Insurance contributions (NIC) on your Temu profits:

• From 2025/26, many self-employed people will no longer pay Class 2 NIC directly, but will still build up entitlement once profits pass a lower threshold, with the option to pay voluntary Class 2 in some cases.
• Class 4 NIC is charged as a percentage of your annual profits (for 2025/26, 6% between £12,570 and £50,270, and 2% above that). Guidance is available on self-employed National Insurance rates.

Both Income Tax and NIC are worked out through your Self Assessment return after the end of the tax year.

Digital records and Making Tax Digital

HMRC’s Making Tax Digital for Income Tax rules will require many sole traders (including Temu sellers) to:

• Keep digital records of income and expenses
• Send quarterly summaries to HMRC using MTD-compatible software

The first phase starts from 6 April 2026 for those with qualifying self-employed or property income above £50,000, with thresholds dropping to £30,000 and then £20,000 in later years.

For Temu sellers, this makes it even more important to get into the habit of keeping clean, digital records from day one.

VAT Rules for Temu Sellers

If you sell through Temu to UK customers, understanding when you must register for VAT is critical:

• From 1 April 2024 the UK VAT registration threshold stands at £90,000 of taxable turnover in any rolling 12-month period.
• You must register if you expect your taxable turnover to exceed £90,000 in the next 30 days.
• Voluntary registration is possible if you’re below the threshold: this can let you reclaim VAT on costs, but also means you must charge VAT and file returns regularly.
  
• Cross-border / marketplace sales complicate things: if you import goods or sell to UK consumers via a foreign seller, you may still need to register regardless of turnover. For example, if your business is based outside the UK and you supply goods to UK customers.

What this means for Temu sellers: If you’re regularly sourcing goods (domestic or abroad) and selling on Temu to UK buyers such that your taxable turnover (goods sold that attract VAT) passes £90,000 within 12 months—or you’re about to pass it—you must register for VAT.

If you are below the threshold but foresee rapid growth, you may consider voluntary registration (weighing benefits and admin burdens).

Temu and the Online Marketplace VAT Rules

Because Temu is an online marketplace facilitating sales into the UK, the VAT rules for overseas sales and marketplaces (“Online Marketplace” or OMP rules) also apply:

• If goods sold to UK customers are located outside the UK at the point of sale, and the sale is made via an OMP, the OMP may be treated as the “deemed supplier” and take responsibility for charging VAT when the consignment value is £135 or less.
• When the goods are in the UK at the point of sale (or the consignment value exceeds £135), normal import VAT/customs rules apply and the OMP may not be responsible.
• HMRC’s guidance confirms that for overseas sellers using a UK online marketplace, the marketplace may need to collect UK VAT on behalf of the overseas seller.
• For Temu sellers based in the UK, you must still understand whether you must charge VAT on your sales, depending on whether you are registered and if you sell via Temu as a “normal seller” rather than an overseas seller via the platform.

Implications for Temu sellers: If you sell via Temu and your goods are located outside the UK, or you use Temu’s fulfilment from abroad, you need to check whether you or the marketplace (Temu) are responsible for the VAT. You also need to watch consignment values and the location of goods because the VAT liability shifts depending on those factors.

Import VAT for Temu Sellers Bringing Goods Into the UK

If you are sourcing goods from abroad (outside the UK) for sale into the UK market, here are the key VAT / import-customs points you must consider:

• When you import goods to the UK, you typically need an EORI number (Economic Operator Registration and Identification) if you are the person responsible for the import.
• For goods imported into the UK, import VAT and possibly customs duty will apply — particularly when the consignment value is over £135 if goods are imported from outside the UK and not handled by the marketplace under the OMP rules.
  
• With consignments valued at £135 or less, sold via an OMP from outside UK, then the VAT may already be charged at point of sale and import VAT/customs duties may not apply in the usual way.
• You must declare import VAT on the relevant customs forms and keep paperwork (commercial invoice, import VAT certificate such as C79 if reclaimable) for VAT reclaim or compliance.

What Temu sellers should do: If you are sourcing from abroad and bringing goods into the UK to sell on Temu (or via Temu UK customers), ensure you have your EORI, properly declare arrival of goods, include import VAT if needed, and keep all records.

If instead the model is that Temu or another fulfilment partner handles import and sells direct to UK customer, you still need to understand whether you are the importer or Temu is — because it affects VAT registration, reclaim, and compliance.

Key HMRC Rules Temu Sellers Must Understand

From 2025, Temu must report seller income and personal details to HMRC under the DAC7 platform reporting rules. HMRC will then match this data against each seller’s Self Assessment tax return.

Any gaps, undeclared income, or inconsistent figures will likely trigger questions or checks. This makes accurate reporting essential, even for small sellers.

Record Keeping Requirements

HMRC expects Temu sellers to keep clear, digital records of:

• Sales
• Stock purchased and sold
• Platform fees and transaction charges
• Refunds and returns

Records must be kept for at least six years, and they should be detailed enough for HMRC to understand how your figures were calculated.

Tools such as Xero, Dext and A2X help automate this process, reduce errors, and align with Making Tax Digital requirements as they roll out.

Import Documentation & Audit Trails

If you import stock from abroad, HMRC may request proof of:

• Commercial invoices
• Proof of origin
• Import VAT and customs duty receipts (such as C79 certificates)

Having a full audit trail protects you during compliance checks and ensures you can claim any allowable import VAT where applicable.

Temu Accounting: A Simple System to Stay HMRC Compliant

Temu sales can grow quickly, so having a simple, consistent accounting system is essential. The steps below help you stay organised, keep accurate records, and avoid issues once Temu begins sharing seller data with HMRC.

Step 1: Track All Sales and Fees Properly

Temu payout summaries rarely show the full picture. HMRC expects accurate records of every order, including refunds, discounts, and platform fees. Reconciling Temu data against your bank payouts ensures you report true profit rather than incomplete figures.

Step 2: Keep Business and Personal Spending Separate

Using a dedicated business bank account makes it easier to track income, match expenses, and avoid mixing personal purchases with business costs. Clean separation also strengthens your position if HMRC reviews your records.

Step 3: Use Cloud Accounting Tools

A digital setup keeps Temu sellers organised and HMRC-ready. A typical workflow is:

• Xero for bookkeeping and VAT
• Dext for scanning receipts and expenses
• A2X for importing Temu sales data and splitting out fees automatically

This reduces manual errors and keeps your accounts aligned with HMRC’s digital-record expectations.

Step 4: Review VAT and Tax Exposure Monthly

Setting aside time each month to check your turnover and profit helps you anticipate VAT registration triggers and upcoming tax bills. It also highlights cashflow issues early.

Step 5: Keep Digital Backups of All Documents

Store receipts, invoices, import paperwork, and Temu reports in digital form. This protects you if Temu updates its platform, deletes old data, or if HMRC requests evidence during an enquiry. Clean digital backups save hours of stress later.

Common Mistakes Temu Sellers Make (and How to Avoid Them)

Temu sellers often start small, but once sales pick up, simple oversight can lead to avoidable HMRC issues. Understanding the most common mistakes—and how to fix them early—helps keep your tax position clean and your business running smoothly.

Mistaking turnover for profit

Many new Temu sellers look only at the payout amount and assume that’s their income. In reality, HMRC taxes profit, which means you must deduct stock costs, platform fees, postage, packaging, and any other expenses linked to the business. Without this breakdown, you might accidentally overstate your income—or understate it and risk penalties.

Fix: Reconcile every sale, refund, and fee so you always know your true profit position.

Ignoring import VAT

If you source stock from China or other overseas suppliers, import VAT is usually charged when goods enter the UK. HMRC can request evidence that you paid this VAT, especially if your business scales. Failing to account for it can distort your profit calculations and cause issues during checks.

Fix: Keep all import paperwork and understand when VAT is due at the border so you can claim it or factor it into your costs.

Missing VAT registration triggers

Online sales can grow rapidly, and Temu sellers often pass the £90,000 VAT threshold without realising it. Once you go over this limit in any rolling 12-month period, you must register for VAT—regardless of whether Temu processes payments for you. HMRC actively monitors marketplace sellers for this.

Fix: Track your turnover each month so you know when you’re approaching the VAT threshold.

Not declaring Temu income because “it’s only a side hustle”

Many sellers start on Temu casually, but once you’re trading with the intention of making profit, HMRC expects you to declare your income. And with DAC7 rules starting in 2025, Temu will report seller earnings directly to HMRC, reducing any margin for error.

Fix: Check whether you exceed the £1,000 trading allowance and register for Self Assessment when required.

Not separating personal and business payments

Mixing personal spending with Temu-related transactions makes bookkeeping messy and creates problems if HMRC ever asks for clarity. It also makes it harder to prove which expenses are genuinely business-related.

Fix: Open a dedicated business bank account and keep all business payments in one place.

No stock records to support cost of goods

Your cost of goods sold (COGS) is a major part of your profit calculation. HMRC may ask how you arrived at your figures, especially if your declared profit looks unusually low. Without stock logs, purchase invoices, and inventory records, HMRC can challenge your numbers.

Fix: Maintain simple stock logs showing what you bought, what you sold, and what’s left in inventory.

Case Study: A UK Temu Seller Going from Side Hustle to Fully Compliant

This hypothetical example shows how a Temu seller can scale up while remaining fully compliant with HMRC:

Amira, a part-time seller from Manchester, began listing small batches of home décor items on Temu in 2024. Within a few months, her sales exceeded the £1,000 trading allowance, which meant she needed to register as self-employed and start reporting her income through Self Assessment.

As her volume increased, she started importing stock from suppliers abroad. By the end of the year, her rolling 12-month turnover reached £90,000, pushing her over the VAT threshold. Because she hadn’t been tracking turnover formally, this came as a surprise—making VAT registration urgent.

To get organised, she moved her bookkeeping into Xero, using Dext to capture receipts and A2X to pull Temu sales data into her accounts automatically. With eAccounts UK supporting her setup, she quickly:

• Reconciled Temu payouts with fees, refunds, and stock costs
• Began forecasting how VAT affected her pricing and margins
• Correctly recorded import VAT on goods sourced overseas
• Reduced manual errors and avoided compliance penalties
• Gained clear monthly visibility of her tax exposure

Within a short period, Amira went from juggling spreadsheets to running a streamlined, compliant operation—fully prepared for HMRC’s platform reporting checks.

When You Should Consider Professional Accounting Support

As your Temu business grows, the admin and compliance requirements grow with it. Once turnover reaches around £30,000–£40,000, VAT planning, cashflow forecasting, and accurate record keeping become far more important—and far easier to get wrong.

You should strongly consider professional accounting support if:

• Your turnover is climbing quickly, especially towards the VAT threshold
• You import goods regularly and need to track import VAT, duties, and supplier documentation
• You sell on multiple platforms such as Temu, TikTok Shop, eBay, Amazon, or Shopify, each with different fees and payout structures
• You’ve been managing everything manually, and errors or missing information are becoming harder to keep on top of

Early mistakes often lead to penalties, delayed VAT registrations, or inaccurate tax returns. Getting help before things escalate protects your business and ensures your finances stay clean as Temu reporting rules tighten.

Wrapping up

Temu can be a profitable way to build an online income, but HMRC still expects accurate reporting, proper bookkeeping, and a clear record of what you earn. With platform reporting rules coming into force, the days of unreported marketplace income are over.

By using digital tools, keeping clean records, and understanding your VAT and tax obligations early, you can run your Temu shop with confidence and avoid the mistakes that catch many new sellers off guard.
