How Does VAT Work for E-commerce in the EU?

For standard taxable EU e-commerce sales to consumers, VAT generally follows the customer's country when goods cross EU borders, subject to a limited €10,000 exception for qualifying EU-established sellers. The Union One Stop Shop (OSS) lets sellers report eligible cross-border sales through one registration instead of registering in every destination country. Marketplaces collect VAT only when specific deemed-supplier rules apply, while foreign stock and imports can create separate obligations.

Start with the movement of goods, not your website

Your store's domain, checkout currency and payment processor do not determine the VAT treatment. Map each sales flow using four facts:

• Where the selling business is established.
• Where the goods are located before dispatch.
• Where the customer receives them.
• Whether the customer is a consumer or a business buying under applicable B2B rules.

Then identify whether you or a marketplace is responsible for VAT on that transaction. This article focuses on physical goods sold to consumers. Digital services, excise goods, special territories and exempt supplies need separate checks.

Before changing checkout settings, have your VAT adviser confirm the treatment of each flow. This is a rules overview, not a documented client case study.

What is the €10,000 EU VAT ecommerce threshold?

The €10,000 threshold is not a general VAT-free allowance. It determines where certain qualifying cross-border consumer sales are taxed.

Broadly, the exception applies to a supplier established in only one EU member state whose goods are dispatched from that state to consumers in other member states. The combined total of eligible intra-EU distance sales and certain cross-border telecommunications, broadcasting and electronic services must not exceed €10,000, excluding VAT, in either the current or previous calendar year.

It is one combined threshold, not a separate allowance for each country. Below it, qualifying sales can remain subject to the seller's home-country VAT treatment. A seller can also elect destination-country taxation, subject to the applicable conditions.

Once the threshold is exceeded, destination-country taxation applies from the sale that takes the business over it. Do not wait until the next financial year to update checkout.

Non-EU-established sellers cannot use this exception. Domestic VAT registration thresholds and the EU cross-border small-enterprise exemption scheme are separate questions. If an exemption may apply, confirm eligibility before implementing standard VAT collection.

How does OSS VAT work?

Union OSS is an optional reporting mechanism for eligible transactions. It does not create a single EU VAT rate.

For covered intra-EU distance sales, charge the VAT rate applicable to the product in the customer's destination country. Report those sales through your member state of identification using a quarterly OSS return. That administration distributes the VAT to the relevant countries.

Once you use Union OSS, include all supplies covered by that scheme rather than selecting destinations individually.

Before implementation, prepare:

• A product-to-tax-category mapping, including reduced-rate products where relevant.
• A destination-country sales report that separates taxable value and VAT.
• A process for refunds, cancellations and corrections.
• A reconciliation between orders, payment settlements and VAT reports.

OSS returns do not provide a mechanism for deducting input VAT. Recovery follows the relevant domestic return or refund procedure. Do not assume VAT paid to suppliers can simply offset your OSS payment.

Does OSS replace local VAT registrations?

No. OSS can reduce destination-country registrations for covered sales, but it does not absorb every obligation.

Holding inventory in another EU country can create local registration and reporting requirements. Moving your own goods between warehouses can also require reporting, even without a customer sale.

Domestic sales from local inventory generally stay outside a regular seller's Union OSS return. Separate provisions apply to certain marketplace deemed suppliers.

Before enabling cross-border fulfilment, ask the logistics provider which countries may hold your stock. Match that list to your VAT registrations and stock-movement reporting. A warehouse setting can change your tax obligations before your next customer order arrives.

When does a marketplace collect VAT?

Marketplace VAT rules do not mean the platform handles every transaction.

An electronic interface can be treated as the deemed supplier when it facilitates certain sales, including:

• Distance sales of imported goods in consignments with an intrinsic value not exceeding €150, subject to the scheme's conditions.
• Supplies of goods already in the EU to consumers where the underlying seller is not established in the EU.

Whether the platform legally facilitates the sale matters. Listing goods or processing a payment alone does not automatically establish deemed-supplier status.

For each marketplace, separate transactions where the platform accounts for VAT from transactions where you remain responsible. Keep the platform's tax reports alongside your order records.

Marketplace collection does not automatically eliminate obligations arising from inventory, imports or stock transfers. It also says nothing about sales through your own website.

How is IOSS different from OSS?

Import One Stop Shop (IOSS) covers eligible distance sales of imported goods in consignments with an intrinsic value not exceeding €150. Excise goods are excluded.

For qualifying IOSS transactions, VAT is collected at checkout. The import can be exempt from import VAT when the required conditions, including valid IOSS information, are met. IOSS returns are monthly, unlike quarterly Union OSS returns.

Without IOSS, import VAT may instead be collected through customs or delivery arrangements. Confirm who is the importer and who pays charges before promising customers an all-inclusive price.

Goods already stored in an EU warehouse are not IOSS sales merely because they were originally manufactured outside the EU.

Build a VAT control your finance team can run

Create a transaction matrix with dispatch country, destination, customer type, channel, VAT collector and reporting route. Assign each flow to domestic VAT, Union OSS, IOSS or another confirmed treatment.

Then test checkout against that matrix and reconcile VAT liabilities separately from marketplace fees and payment deductions. A net settlement is not a reliable VAT calculation.

If consumer prices include VAT, a different destination rate changes the revenue retained at the same selling price. Review margin by destination after tax settings change.
