OSS vs French VAT Registration: Which Do You Need?

The European Commission describes OSS as an optional mechanism that lets a business register in one Member State of identification and declare VAT due in other Member States on supplies that fall within the selected scheme. Its revised 2026 guide is explicit that OSS returns are additional to, and do not replace, domestic VAT returns.

A French VAT number serves a different purpose. It identifies the company for French customs and tax reporting when its own transactions create obligations in France. The practical question is therefore not which system is better. It is which transaction belongs in which system. Our OSS registration and returns service scopes the cross-border sales, while our French VAT registration service covers the local French route where it remains necessary.

For a typical ecommerce seller, the Union scheme covers intra-Community distance sales of goods. The goods must be dispatched or transported from one Member State to a non-taxable customer in another Member State. The seller applies the VAT rate of the destination country, reports the sale through its Member State of identification and pays the combined OSS liability there.

The Union scheme can also cover certain B2C services supplied in a Member State where the supplier is not established. A marketplace acting as deemed supplier can use it for covered distance sales and, in that special capacity, certain domestic supplies. Those extensions do not make ordinary domestic sales by every seller eligible for OSS.

Once a business opts into an OSS scheme, the Commission says it must use that scheme for all supplies falling within it in all relevant Member States. It cannot place French distance sales in OSS but file equivalent Spanish or German distance sales locally for convenience. The legal entity and full EU sales footprint must be configured consistently.

The French tax authority requires registration when a foreign business performs transactions that need French customs identification or French VAT returns. Its current list includes imports using import VAT self-assessment, French domestic sales for which the seller is liable, exports from France, intra-Community supplies from France and transfers of the seller's own stock.

Stock is the most common reason OSS and a French number coexist. Moving your own goods into a French fulfilment centre can create a French intra-Community acquisition before any customer order is shipped. Later, a sale from that warehouse to a French consumer is domestic. Passive storage between those events is not another taxable transaction. Neither the acquisition nor the later domestic sale becomes a cross-border distance sale simply because the company is registered for OSS elsewhere.

Start with the transaction map in our French VAT number decision tree. If the same entity imports goods, receives an own-goods transfer or makes local supplies in France, local registration should be assessed before deciding how its consumer sales are reported.

The EUR 10,000 threshold can keep qualifying B2C telecommunications, broadcasting and electronic services, together with qualifying intra-Community distance sales of goods, taxable in the supplier's Member State. It is a combined annual threshold, excluding VAT, tested for the current and preceding calendar year.

The Commission's revised guide limits this rule to a supplier established in only one Member State and, for goods, to dispatches that start in that Member State of establishment. Distance sales made from stock in another Member State are not included in the threshold calculation and remain taxable at destination. Non-EU-established suppliers cannot use the threshold.

A qualifying seller can opt for destination taxation before exceeding the threshold. Registering for Union OSS makes that choice and binds the seller to the destination rule for two calendar years. Do not use the threshold as a general exemption from French stock, import or local-return obligations.

IOSS is the import scheme for eligible distance sales of goods dispatched from outside the EU in consignments with an intrinsic value not exceeding EUR 150. Goods already stored in an EU warehouse are not distance sales of imported goods and do not move into IOSS merely because they originally came from a third country.

A marketplace may be deemed supplier for defined sales and may report the customer-facing transaction itself. The underlying seller must still test its imports and stock movements. Read our deemed-supplier guide and the explanation of why marketplace VAT collection does not automatically remove seller registrations.

Apply the table to each legal entity and dispatch route. A business can match several rows, which is why the answer is often both rather than one or the other.

The main operational risk is duplication or omission. Create one row per transaction type, not one row per marketplace. Assign a single reporting destination to the customer sale, then record any separate import or own-stock movement that happens before it.

Reconcile the matrix to the order ledger, warehouse reports and customs entries for every period. OSS is generally quarterly, while the French domestic timetable depends on the company's filing profile. A shared source ledger must therefore support different cut-off dates without counting the same sale twice.

A German company sells to French consumers. Standard products are dispatched from its German warehouse, and a fast-moving range is stored in France. The same German company owns both inventories and is registered for Union OSS in Germany.

Eligible Germany-to-France consumer sales can be declared through German Union OSS with French VAT. The arrival of the company's own goods in France requires a separate French analysis. Sales from French stock to French consumers are domestic French sales, while sales from French stock to consumers in other Member States can be eligible distance sales through Union OSS.

The company therefore keeps its German OSS registration and may also need a French VAT number. Its data file separates German dispatches, French stock arrivals, French domestic orders and France-to-other-EU orders before each return is prepared.

The Commission's July 2026 guide notes that a new OSS scheme for transfers of own goods is scheduled to enter into force on 1 July 2028. That future simplification is part of the wider VAT in the Digital Age changes and is not the current reporting route.

Do not postpone a French registration required by stock arriving in 2026, 2027 or the first half of 2028. Apply the rules in force for the transaction date, then review the registration footprint when the new scheme becomes available. Our ViDA implementation timeline tracks the staged changes.

Map the entity, stock countries, importers, dispatch origins, customer types and marketplace roles before the first order. Then assign each flow to exactly one customer-sale return and any separate stock or import declaration. This produces the real answer to OSS versus French registration without relying on a marketplace setting or a single sales threshold.

If both routes apply, use one reporting calendar and one reconciled dataset. That is simpler and safer than trying to reconstruct French stock movements after OSS returns have already been filed.
