For an overseas company, moving stock into a British warehouse changes the VAT position far more significantly than many businesses expect. UK VAT registration for overseas companies using a UK fulfilment centre is rarely determined by turnover alone. The crucial questions are where the goods are physically located when they are sold, who owns them, who imports them, how the customer purchases them and whether an online marketplace is involved.

A US company can have no office, employees or directors in Britain and still become liable for UK VAT from its first taxable sale from stock held in England. A German manufacturer can send goods to a Birmingham 3PL and create a different VAT result from shipping the same goods directly from Germany after receiving each order. An Amazon seller using FBA may face yet another treatment because the marketplace can become responsible for VAT on certain consumer transactions.

The warehouse is therefore not merely a logistics decision. It changes the VAT supply chain.

The most expensive problems usually appear when the commercial team treats VAT as something to organise after the first shipment. By that stage goods may already have been imported under the wrong party’s EORI number, import VAT may be difficult to recover, customer prices may have been set without allowing for VAT, and HMRC may consider the correct registration date to be earlier than the company expected.

Does using a UK fulfilment centre or 3PL require UK VAT registration?

An overseas company will commonly need UK VAT registration where it owns goods stored in the UK and makes taxable UK sales from that stock. Unlike an ordinary UK-established business, a non-established business generally cannot rely on the £90,000 domestic VAT registration threshold when making taxable supplies in the UK.

This is the point overseas businesses most frequently misunderstand.

Management may look at annual UK turnover of £20,000 or £40,000 and conclude that registration is unnecessary because the figure is below the normal VAT threshold. That reasoning can be correct for a small UK-established business, but it does not normally protect a non-established taxable person making taxable UK supplies.

Suppose a Delaware company imports £50,000 of fitness products into a fulfilment centre near Manchester. Customers order through the company’s own Shopify website and the warehouse picks, packs and delivers the products throughout Britain.

The company may have no UK employees, no UK office and no UK subsidiary.

Nevertheless, the goods are already in Britain when the sale takes place. The company owns them and sells them directly to British customers. The sale is therefore fundamentally different from an order shipped from the United States after the customer purchases it.

HMRC’s guidance specifically states that an overseas seller owning goods located in the UK at the point of sale must register and account for VAT when making direct sales to UK customers.

From a practical advisory perspective, I therefore ask about the stock flow before asking about turnover.

Where is the inventory before the customer clicks “buy”?

Who owns it at that moment?

Who appears as seller on the invoice?

Who receives the customer’s money?

Those questions usually reveal the VAT position more quickly than reviewing the company’s annual revenue.

Why the location of the goods matters more than the location of the company

VAT on goods is closely connected with the physical movement and location of those goods. When an overseas company places stock in a UK warehouse before sale, subsequent domestic sales can become UK taxable supplies even though every management decision, employee and shareholder remains outside Britain.

This distinction seems obvious once explained, yet it is responsible for a surprisingly large number of retrospective VAT registrations.

Consider two Canadian companies selling identical kitchen appliances.

The first keeps all inventory in Toronto. A British customer places an order, and that specific order is then shipped to the UK.

The second company sends 2,000 appliances to a Leicester fulfilment centre before any particular customer has ordered them. When an order arrives, the 3PL delivers from Leicester to the customer.

Commercially, both companies may describe themselves as Canadian eCommerce businesses selling into Britain. For VAT purposes their transactions are not necessarily the same.

In the second model, stock is already in Britain at the point of sale. That fact becomes central.

This is why a move from “cross-border fulfilment” to “local fulfilment” should always trigger a VAT review. What appears to management as a delivery improvement — reducing delivery from seven days to next-day — may simultaneously move the business into a domestic UK VAT model.

The same issue arises when an overseas manufacturer initially ships products directly to British distributors and later decides to hold buffer stock at a UK 3PL. The commercial contract with the distributor may remain unchanged, while the VAT analysis changes because the goods are now supplied from stock already situated in Britain.

Does a UK 3PL create a UK fixed establishment?

Using an independent UK fulfilment company does not automatically give an overseas business a UK fixed establishment. HMRC looks for a sufficiently permanent presence with appropriate human and technical resources. Merely having inventory, a warehouse address, a VAT number or an independent service provider in Britain is not by itself the same as being established here.

This distinction is important because businesses often hear two apparently contradictory statements:

“You have goods in the UK, so you need UK VAT registration.”

“You do not have a UK establishment.”

Both statements can be correct.

VAT registration and VAT establishment are different concepts.

Imagine a Singapore company that contracts with an independent fulfilment warehouse in Birmingham. The warehouse serves hundreds of unrelated clients. Its employees work for the fulfilment company, not the Singapore business. The Singapore company does not control individual warehouse staff, manage the premises or operate its business from the facility.

Holding goods there does not, on those facts alone, mean that Birmingham has become the company’s headquarters or fixed establishment.

HMRC’s own registration guidance says an overseas business’s principal place of business should not simply be a UK fulfilment centre or third-party address.

The analysis can become more complicated where an overseas company has dedicated UK employees, permanently available technical facilities, a UK sales operation or substantial control over local resources. At that point the establishment question deserves a separate review.

For most conventional third-party fulfilment relationships, however, the reason for VAT registration is not that the warehouse has somehow transformed the company into a British business.

The reason is that the overseas company is making taxable transactions involving goods located in Britain.

That is a much more accurate way to understand the position.

Direct sales from a UK warehouse through Shopify or your own website

An overseas company selling directly from UK-held inventory through Shopify, WooCommerce or its own website will normally be responsible for UK VAT itself. The marketplace deemed-supplier rules do not generally transfer that responsibility to Shopify merely because Shopify technology is used to operate the store.

This distinction between a website platform and an online marketplace is commercially important.

A French cosmetics company may use Shopify for checkout, a London 3PL for warehousing and Stripe for payments. None of those service providers necessarily becomes the seller of the goods.

The French company remains the merchant selling the product.

If the goods are stored in Britain when a customer buys them, the company should normally consider VAT registration from the beginning of its taxable UK activity rather than waiting for turnover to approach £90,000. HMRC describes overseas businesses making taxable UK supplies as being liable to register regardless of the ordinary domestic turnover threshold.

Pricing must be planned at the same time.

Suppose a product is advertised to consumers for £120. If that figure is VAT-inclusive and the product is standard-rated, £20 represents VAT and £100 represents net sales revenue.

A business that built its margin calculation around £120 of revenue has just lost £20 of expected revenue before considering warehouse charges, advertising, payment fees or corporation tax.

That is why I prefer to review VAT before a UK launch rather than after the first quarter. Registration paperwork is rarely the main commercial issue. Pricing is.

Businesses planning this structure should consider completing their UK VAT registration before UK sales begin, rather than using the first customer invoice as the moment to discover how the VAT rules work.

Amazon FBA and other online marketplaces are different

Where an overseas seller’s goods are already located in the UK and are sold to consumers through a qualifying online marketplace, the marketplace may be treated as making the sale for VAT purposes. The marketplace then accounts for VAT, while the overseas seller is generally treated as making a deemed zero-rated supply to the marketplace.

Amazon FBA therefore needs to be analysed differently from a Shopify fulfilment model.

Suppose a US Amazon seller sends inventory to an Amazon fulfilment centre in Britain. The products are imported, placed into UK stock and later purchased by British consumers through Amazon.

For qualifying consumer transactions, Amazon may account for the VAT collected from the final customer.

That does not make the seller’s VAT position disappear.

The overseas seller remains responsible for its import arrangements. When it imports goods into the UK, import VAT and customs duty may arise. HMRC’s marketplace guidance confirms that the overseas seller remains liable for import VAT and customs duty when the goods are first imported.

When the consumer sale occurs, the seller can be treated as making a deemed zero-rated supply to the marketplace. This mechanism is deliberately structured so that a registered overseas seller can, subject to the normal conditions, recover import VAT incurred on the goods.

This produces an unusual result that often surprises Amazon sellers: a VAT registration can remain financially valuable even when Amazon itself accounts for much of the output VAT on consumer sales.

There is another important exception.

If goods held in Britain are sold through the marketplace to a UK VAT-registered business that provides a valid VAT number, the seller can become responsible for the VAT treatment of that B2B sale rather than the marketplace.

A seller therefore cannot safely conclude, “Amazon deals with VAT, so we have no UK VAT responsibilities.”

The correct conclusion is: identify precisely which transactions Amazon accounts for and which transactions remain the seller’s responsibility.

Should an Amazon FBA seller still register if the marketplace pays the VAT?

Often, yes. An overseas seller using UK FBA may register to recover qualifying import VAT and report deemed zero-rated supplies even where the marketplace accounts for VAT on consumer sales. HMRC also allows certain overseas sellers making only these zero-rated deemed supplies to seek exemption from registration, but exemption can prevent recovery of import VAT.

This is one of the areas where the cheapest administrative option is not necessarily the cheapest commercial option.

Assume an Australian company imports goods with a customs value that produces £30,000 of UK import VAT during the year. All sales are B2C through an online marketplace, and the marketplace accounts for VAT on those consumer transactions.

The company might technically examine whether registration exemption is available.

But giving up registration may also mean giving up the practical mechanism through which that £30,000 import VAT could otherwise be recovered.

The decision therefore needs a calculation, not a slogan.

An experienced adviser will compare the compliance cost of maintaining a VAT registration with the potential input VAT recovery, the likelihood of B2B sales, expected changes in sales channels and future plans for direct sales.

I have seen businesses make the mistake of structuring everything around today’s marketplace activity and then launch a Shopify website six months later without revisiting the VAT position. At that point they have moved from a model in which the marketplace accounted for much of the VAT to one in which the business itself is making direct domestic supplies.

The sales channel matters.

Importing stock into a UK fulfilment centre: the EORI issue

VAT registration and customs registration should be planned together. An overseas company importing its own stock into Great Britain will commonly need a GB EORI number, and the company shown as importer should be consistent with the party that owns the goods and intends to recover import VAT. Poorly structured import documentation can make VAT recovery much harder later.

One of the most frustrating situations arises when a company has correctly registered for VAT but the customs documents show somebody else as importer.

This frequently happens because the logistics process was set up before the tax process.

A manufacturer in China ships goods to a UK warehouse. A freight forwarder asks urgently for customs details. Someone instructs the broker to use the fulfilment company’s details, the customer’s details or another party’s EORI simply to get the shipment moving.

The goods arrive.

Several months later the accountant asks for evidence supporting the import VAT claim.

That is when everyone discovers that the customs documentation does not reflect the commercial transaction.

A cleaner structure is normally established before shipment: determine who owns the goods at importation, who is importer of record, whose EORI is used, how customs duty will be paid and how import VAT will be recovered.

Overseas companies unfamiliar with British customs procedures should review the requirements for a UK EORI number for overseas companies at the same time as their VAT position.

Do not treat EORI and VAT numbers as interchangeable.

An EORI identifies an economic operator within the customs process. A VAT registration determines VAT reporting obligations. They interact closely at importation, but they perform different functions.

The connection becomes particularly important when postponed VAT accounting is used.

Postponed VAT accounting and cash flow

Postponed VAT accounting allows an eligible UK VAT-registered importer to account for import VAT through its VAT Return instead of paying the VAT upfront at the border and recovering it later. For an overseas business importing substantial inventory, this can remove a significant cash-flow burden, but the customs declaration must be completed correctly.

Consider a shipment with £200,000 of taxable import value.

If £40,000 of import VAT must be physically funded at the border and later reclaimed, the business may have tens of thousands of pounds tied up purely because of the VAT cycle.

Postponed VAT accounting can allow the import VAT to be declared and, where recoverable, reclaimed through the same VAT Return.

Economically, that can make a significant difference.

However, postponed VAT accounting is not something the accountant can reconstruct casually three months after the import.

The importer should tell the customs representative how the import VAT is to be handled, the correct VAT registration number needs to be associated with the import declaration, and the business must obtain and reconcile its postponed import VAT statements. HMRC states that VAT recorded through PVA appears on monthly statements linked to the importer’s EORI details.

A common operational weakness is that the freight forwarder and the VAT accountant never communicate.

The freight forwarder knows what was declared to customs.

The accountant knows what should go on the VAT Return.

Nobody compares the two.

Good compliance joins those processes together.

Should VAT registration be completed before stock arrives in Britain?

Where an overseas company intends to hold stock in Britain and make taxable UK sales, the safest approach is usually to establish the VAT and customs structure before the first commercial shipment. The precise effective date depends on the facts, but delaying the application until several months of UK sales have accumulated creates unnecessary exposure.

There is a difference between registering because a business genuinely intends to trade and applying for a tax number without evidence of real commercial activity.

HMRC can ask what the company plans to sell, where stock will be held, who its suppliers are and how the UK operation will function.

That should not discourage a genuine business from applying early enough.

Quite the opposite.

A company preparing a proper UK launch should already possess useful evidence: a fulfilment agreement, supplier contracts, purchase orders, freight arrangements, a website, marketplace account or customer negotiations.

Where taxable UK supplies are expected, the effective VAT registration date should be reviewed before invoices start being issued.

If sales have already commenced, simply choosing today’s date on an application does not erase an earlier liability.

This is why late registration cases require reconstruction. Sales from the correct historical date may have to be reviewed, output VAT calculated and returns prepared retrospectively.

The financial pain becomes particularly severe when consumer prices were treated as fixed. If a company sold products for £120 without recognising that the price should have contained VAT, it may not be commercially possible to return to hundreds of customers months later and request another £20.

The VAT may have to come out of the £120 already collected.

Businesses unsure about their starting date should review the evidence before filing rather than selecting an arbitrary date.

What evidence does HMRC normally expect from an overseas company?

HMRC wants to establish that the applicant is a genuine business, that the stated UK activity exists or is genuinely intended, and that the proposed VAT treatment matches the commercial facts. Overseas applications therefore tend to be stronger when the documentary evidence tells one consistent story from supplier to warehouse to customer.

A VAT application should make commercial sense when read by somebody who knows nothing about the company.

Suppose a Hong Kong electronics business says it will import goods into Britain and sell through Amazon and its own website.

I would expect its records to be capable of demonstrating that model through a coherent collection of evidence: incorporation details, ownership information, contracts with suppliers, fulfilment arrangements, marketplace records, purchase orders, shipping information, bank or payment evidence and details of intended UK customers.

Not every document is necessarily submitted with every application. HMRC may nevertheless request additional evidence during its review. The practical requirements are considered in more detail in what documents are needed for UK VAT registration.

What causes delays is inconsistency.

The VAT application gives one trading address.

The website gives another.

Amazon shows a shortened company name.

The supplier invoice names the shareholder personally.

The warehouse contract is signed by a different group company.

The importer uses another entity’s EORI.

None of those points automatically proves anything improper. Together, however, they force HMRC to ask additional questions because the legal entity carrying on the trade is no longer clear.

A strong application removes those ambiguities before HMRC finds them.

Where an application has already become difficult, it is worth understanding why HMRC may delay or refuse a VAT registration rather than repeatedly submitting the same incomplete explanation.

A fulfilment agreement is not just a logistics document

For VAT purposes, a 3PL contract helps establish who owns the stock, where goods are stored, what the fulfilment company actually does and whether the overseas business retains responsibility for selling the goods. Those facts can be more useful than the labels used in the contract itself.

When reviewing a fulfilment arrangement, I am less interested in whether the provider calls itself a “warehouse partner”, “fulfilment agent” or “logistics platform” than in what actually happens.

Does the overseas business retain legal title to inventory?

Can it withdraw its goods?

Who decides the selling price?

Who contracts with the customer?

Who bears the risk of customer returns?

Who issues sales invoices?

Does the 3PL merely pick and pack orders, or does it buy and resell the merchandise?

These distinctions can change the VAT analysis.

Most conventional fulfilment providers are service providers. They receive somebody else’s goods, store them and dispatch them according to instructions. The seller remains the seller.

A distributor arrangement can be different. If a UK distributor genuinely buys inventory from the overseas manufacturer and resells it on its own account, the VAT chain may involve a sale to that distributor rather than thousands of domestic retail sales by the overseas manufacturer.

The contract must reflect commercial reality.

Renaming a fulfilment centre a “distributor” does not make it one.

The Fulfilment House Due Diligence Scheme matters even though it applies to the warehouse

UK fulfilment businesses storing certain imported goods for overseas sellers may fall within HMRC’s Fulfilment House Due Diligence Scheme. The scheme places obligations on the fulfilment business itself, but overseas sellers feel its effects because legitimate warehouses frequently require VAT, EORI and business information before accepting or continuing to store stock.

This explains a situation that sometimes puzzles overseas businesses.

A 3PL requests a UK VAT number.

The seller replies that its accountant has said Amazon accounts for VAT.

The warehouse still asks for evidence.

That does not necessarily mean the warehouse is interpreting the seller’s VAT liability incorrectly. The fulfilment business has its own due-diligence obligations.

HMRC’s fulfilment-house regime is designed in part to prevent UK warehouses being used to facilitate VAT non-compliance by overseas sellers. Approved operators may therefore need to verify information relating to customers whose imported goods they store. HMRC’s internal guidance also recognises VAT exemption references in circumstances where an overseas customer has obtained exemption from registration.

From a commercial perspective, this makes formal compliance increasingly difficult to avoid.

Warehouse onboarding, customs clearance, marketplace verification and VAT registration are no longer isolated processes. Information entered into one system is often compared with information available elsewhere.

Consistency is therefore valuable not only for HMRC but for the business’s entire UK supply chain.

VAT Returns after registration: where many problems actually begin

Receiving a UK VAT number is the beginning of compliance, not the end. The business must maintain appropriate digital records, submit VAT Returns through compatible Making Tax Digital software, reconcile sales and imports, and distinguish transactions where the company accounts for VAT from those where a marketplace does so.

Registration receives disproportionate attention because it feels like the difficult step.

For businesses using fulfilment centres, the greater long-term risk is usually data reconciliation.

One system contains Shopify sales.

Another contains Amazon transactions.

A third contains warehouse dispatches and returns.

A customs broker holds import declarations.

HMRC produces postponed import VAT statements.

Stripe, Amazon or another processor records money actually received.

The accounting software has to turn those different data streams into a defensible VAT Return.

That is why our approach to UK VAT Returns for overseas companies focuses on the underlying transactions rather than simply filling nine boxes.

If an overseas seller imports inventory using postponed VAT accounting, the relevant import VAT generally needs to be reflected through the VAT Return. HMRC guidance specifies how PVA values feed into boxes 1, 4 and 7.

Marketplace sales require separate analysis.

Direct Shopify sales cannot simply be combined with Amazon sales and subjected to one VAT percentage without checking who was legally responsible for VAT on each transaction.

Returns, refunds, stock losses, promotional discounts, credit notes and B2B sales also require correct treatment.

The return may be only nine boxes.

The records behind those boxes are where the real work is done.

Making Tax Digital for an overseas company

An overseas business with a UK VAT registration generally falls within Making Tax Digital for VAT in the same way as other VAT-registered businesses. Digital VAT records must be maintained and VAT Returns submitted using compatible software or appropriate bridging software unless a specific exemption applies.

This matters particularly for businesses whose accounting remains entirely outside Britain.

A company in Dubai may maintain its main accounts in UAE software.

A US business may use QuickBooks configured around US sales tax.

A Chinese company may maintain operational records in a local ERP.

None of those arrangements prevents UK VAT compliance, but the data must be capable of producing reliable UK VAT records.

I would not automatically replace an overseas company’s entire accounting platform just because UK registration is required.

Instead, the sensible question is whether the existing system can feed a compliant VAT reporting process.

Sometimes an established ERP can export the necessary transactions and compliant bridging software can submit the return. In other cases, a dedicated UK ledger is cleaner.

The important point is that the final VAT calculation should remain traceable to underlying digital records.

Copying totals manually between unrelated spreadsheets every quarter is exactly the kind of process that eventually produces unexplained differences.

A good system lets somebody reviewing the business six months later trace a VAT Return figure back to the sales, imports and adjustments from which it arose.

Do not confuse the reverse charge with VAT on UK stock sales

The reverse charge can apply to certain cross-border services and particular transactions, but it does not generally remove an overseas seller’s obligation to account for VAT on direct domestic sales of goods already stored in Britain. Goods and services need to be analysed separately rather than applying the phrase “reverse charge” to every cross-border transaction.

I occasionally see invoices where “reverse charge” has been added simply because one party is outside the UK.

That is not how the rules work.

A US company storing products in Birmingham and selling those products directly to a consumer in Leeds does not turn the transaction into a cross-border service merely because the company itself is American.

The goods are already in Birmingham.

The supply of those goods must be analysed accordingly.

Conversely, the company may purchase professional, advertising, technology or other services from suppliers in different countries where business-to-business place-of-supply and reverse-charge rules are relevant.

Even invoices issued by the 3PL deserve attention. The VAT treatment of fulfilment, storage and associated services depends on the nature of the services and the place-of-supply rules. Businesses should not assume automatically that every British supplier invoice must contain recoverable UK VAT simply because the supplier has a UK address.

This becomes particularly relevant where large warehousing charges are involved.

Incorrect VAT charged by a supplier is not automatically recoverable merely because the customer has paid it.

What happens if the company registers late?

Late registration can result in VAT becoming payable retrospectively from the correct effective date, together with potential penalties and interest depending on the circumstances. For an overseas retailer, the most serious commercial problem is often that historical consumer prices cannot be increased retrospectively, leaving the business to fund VAT from revenue already collected.

Suppose an overseas seller begins direct sales from UK stock in January but discovers the VAT problem in October.

It has collected £240,000 from consumers.

The company cannot simply tell HMRC, “We were below £90,000 for the first few months.”

If the business was a non-established taxable person required to register from the relevant earlier date, HMRC can establish the registration retrospectively.

Failure to notify liability to register can also create a penalty exposure.

The first task is therefore not to calculate a penalty.

The first task is to establish the correct liability.

When should registration actually have taken effect?

Which historical sales were taxable?

Which sales were handled by online marketplaces?

Was VAT already accounted for somewhere else in the supply chain?

What input VAT is recoverable?

What import VAT evidence exists?

Only after reconstructing those facts can the real net exposure be calculated.

Businesses facing that situation should avoid improvising corrections through the next VAT Return. Historical registration and historical return corrections need a structured approach.

Once registered, continuing delays create additional risks. HMRC’s present regime uses penalty points for late VAT Returns and separate penalties and interest for late payment.

Further practical detail is available in our guidance on late UK VAT Returns and HMRC compliance.

The most common VAT mistakes when using a UK fulfilment centre

Most fulfilment-centre VAT problems are not caused by obscure legislation. They arise because logistics, marketplace, customs and accounting decisions are made independently. A business can avoid the majority of serious problems by deciding who owns the stock, who imports it, who sells it and who accounts for VAT before the first shipment leaves the supplier.

The recurring problems I would check first are:

1. Waiting for UK turnover to reach £90,000 even though the seller is a non-established business making taxable UK supplies; importing goods under the wrong party’s EORI or customs identity; assuming the fulfilment centre becomes responsible for VAT because it physically dispatches the goods; treating Shopify and Amazon as if the same marketplace VAT rules applied to both; failing to separate marketplace B2C transactions from direct and VAT-registered B2B sales; claiming import VAT without matching customs evidence; and submitting VAT Returns from payment-platform totals without reconciling refunds, fees, import records and marketplace reports.

These are rarely isolated mistakes.

One incorrect assumption at the beginning can spread through the entire process.

If the wrong entity imports the inventory, the import VAT evidence may be wrong.

If the VAT evidence is wrong, the VAT Return may be wrong.

If pricing was established without VAT, the margin may be wrong.

If marketplace data is then mixed with direct sales, output VAT may be wrong as well.

The solution is not a more sophisticated spreadsheet.

It is getting the transaction chain right first.

A practical example: US Shopify company using a Birmingham 3PL

A US company importing its own stock into a Birmingham 3PL and selling directly through Shopify will typically need to consider a GB EORI, UK VAT registration, correct import arrangements, VAT-inclusive consumer pricing, Making Tax Digital records and continuing VAT Returns. The 3PL normally remains a logistics provider rather than the party responsible for the seller’s VAT.

Assume the company purchases products in China.

The Chinese manufacturer ships a commercial quantity directly to Birmingham.

The US company remains owner of the inventory.

Its UK 3PL unloads, stores and dispatches goods.

British consumers place orders on the US company’s own website.

The US company receives the money.

This is a classic structure in which VAT should be designed before the first commercial shipment.

The US business should determine who will act as importer and obtain the appropriate customs registration. Its UK VAT position should be established before taxable domestic sales begin. If postponed VAT accounting is intended, the customs broker needs clear instructions and the declaration should use the appropriate details.

Shopify sales then need to be recorded with the correct UK VAT treatment.

The fulfilment company’s monthly stock movement should be reconciled periodically against recorded sales, returns and inventory.

If a large quantity of inventory leaves the warehouse but cannot be matched to sales, transfers, samples or returns, that is something I would want investigated before HMRC ever asks the question.

The accounting records should explain the physical movement of the goods.

That connection between stock and VAT is particularly important for fulfilment businesses.

A practical example: Canadian Amazon FBA seller

A Canadian seller importing goods into UK Amazon FBA faces a different reporting model. Amazon may account for VAT on qualifying UK consumer sales from UK-held stock, while the Canadian company can have deemed zero-rated supplies and may register to recover eligible import VAT. B2B transactions and direct sales still need separate treatment.

Assume the seller imports £300,000 of products annually.

Most customers are consumers.

The goods remain in Amazon warehouses until purchased.

Amazon accounts for VAT on the qualifying consumer sales.

The seller should not simply omit those transactions from its accounting records because Amazon paid the output VAT.

The underlying deemed supplies, import VAT and stock movement remain relevant to the seller’s VAT accounting.

Now assume the company launches its own website and sends some orders from the same FBA or third-party stock.

Those direct transactions can change the VAT analysis because the company itself may now be making domestic taxable sales to UK customers.

Alternatively, suppose a British VAT-registered corporate customer buys through the marketplace and provides its VAT number. The liability for that transaction needs to be identified separately rather than assuming Amazon treated it exactly like the consumer orders.

This is why marketplace reports must be analysed by transaction type, not simply downloaded and entered as one monthly sales figure.

A practical example: European manufacturer using UK buffer stock

A European manufacturer can create a UK VAT obligation even without an eCommerce business. If it imports or transfers its own stock to a UK 3PL and later supplies British wholesalers or commercial customers from that inventory, the domestic stock position must be reviewed independently from the company’s establishment and turnover abroad.

Consider a Dutch engineering company.

Its UK clients previously ordered machinery components from Rotterdam.

Delivery took eight days.

To improve service, the company places three months of inventory in a warehouse near Leeds.

Customers continue dealing with the Dutch sales department and invoices are issued from the Netherlands.

Management may feel that nothing fundamental has changed.

From a logistics perspective, perhaps not.

From a VAT perspective, something very important has changed: the goods are in Britain before the customer sale.

The company should therefore review the UK VAT consequences of the stock transfer, import arrangements and subsequent domestic supplies.

This type of case illustrates why VAT cannot be determined from the invoice address alone.

A Dutch invoice does not automatically make the underlying supply a Dutch transaction.

The physical and contractual facts determine the treatment.

What about Northern Ireland?

Northern Ireland requires additional care because goods transactions can be subject to rules that differ from those applying in England, Scotland and Wales. A business using a Belfast fulfilment centre should therefore not automatically apply a VAT model designed for stock held in Manchester, Birmingham or London.

Most overseas businesses referring to a “UK warehouse” actually mean a warehouse in Great Britain.

That distinction should be confirmed.

Northern Ireland retains a special VAT treatment for certain goods transactions connected with the EU. HMRC guidance for overseas sellers therefore contains specific Northern Ireland provisions alongside the rules for Great Britain.

If inventory will be held in Northern Ireland, moved between Northern Ireland and the EU, or supplied to customers in both Great Britain and the EU, the structure deserves separate analysis before stock movements begin.

I would not simply copy the Great Britain model and change the warehouse postcode.

When should an overseas company appoint a UK VAT agent?

A VAT agent becomes particularly useful where an overseas company combines imports, UK inventory, marketplace and direct sales, postponed import VAT and multiple data systems. The purpose is not merely to submit forms; it is to keep customs, transaction data and HMRC reporting aligned as the business develops.

A simple business making a handful of predictable transactions may be capable of handling much of its VAT administration internally.

The position changes when operational complexity increases.

Imagine a company importing from China, holding stock with two UK warehouses, selling through Amazon and Shopify, making some wholesale B2B supplies and processing returns through a separate logistics centre.

The problem is no longer calculating 20%.

The problem is deciding which party accounts for VAT on each transaction and ensuring the accounting data proves the answer.

A competent UK VAT agent for overseas businesses should therefore understand the commercial model, not simply receive a spreadsheet two days before the VAT deadline.

When we review a new overseas client at VAT Number UK, the questions normally begin with how the business actually trades: suppliers, Incoterms, importer arrangements, warehouses, marketplaces, sales channels, customer types and money flows.

Only then does it make sense to discuss the VAT Return.

What HMRC is likely to examine during a compliance review

HMRC normally wants evidence that VAT Returns reflect real underlying transactions. For a fulfilment-based overseas business, that can include sales records, VAT invoices, marketplace reports, customs declarations, postponed import VAT statements, purchase invoices, bank records, warehouse information and explanations of how the company’s UK supply chain works.

The strongest defence during an HMRC compliance check is not an argument.

It is a clean audit trail.

If a VAT Return shows £80,000 of recoverable import VAT, the reviewer should be able to see how that figure was produced.

If Amazon accounted for VAT on certain sales, the records should distinguish those transactions from the seller’s own taxable supplies.

If £500,000 of products entered a warehouse during the year, inventory records should broadly explain where those goods went.

HMRC does not expect every commercial business to operate perfectly. Adjustments, returns, damaged inventory and accounting corrections are normal.

What creates concern is unexplained inconsistency.

A repayment claim unsupported by customs records attracts attention.

Large sales movements that do not agree with marketplace records attract attention.

Repeated VAT Return corrections attract attention.

The purpose of good VAT accounting is therefore not merely to avoid mistakes. It is to make the figures explainable.

Our detailed step-by-step UK VAT Return guidance explains how the reporting process should be supported by the underlying records rather than treated as a quarterly administrative exercise.

VAT registration should be part of the fulfilment decision, not an afterthought

For an overseas company, using a UK fulfilment centre can materially improve delivery times, customer experience and commercial credibility, but the tax structure needs to be designed at the same time. VAT registration, customs identity, importer status, marketplace treatment and accounting systems should be settled before significant stock begins moving into Britain.

The most successful UK launches I see tend to have one characteristic in common: management decides how the transaction will work before asking how to report it.

The company knows which legal entity owns the stock.

It knows who imports it.

The customs broker has the correct EORI and VAT instructions.

The fulfilment agreement reflects the intended relationship.

Prices have been modelled with VAT included where appropriate.

Amazon sales are distinguished from direct website sales.

Accounting software is ready before the first VAT Return becomes due.

That structure removes most of the avoidable problems.

By contrast, businesses that treat VAT as a registration number to obtain after opening the warehouse often spend considerably more time correcting the past than planning the future.

For an overseas company using a UK fulfilment centre or 3PL, the central question is therefore not simply, “Do we need a VAT number?”

The better questions are:

Who owns the goods when they enter Britain?

Who imports them?

Where are they when they are sold?

Who makes the legal supply to the customer?

Who accounts for the VAT?

Who holds the evidence supporting import VAT recovery?

And can the accounting system prove all of that to HMRC?

Once those questions are answered correctly, UK VAT registration becomes part of a coherent commercial structure rather than an isolated compliance exercise.
