Several countries, several marketplaces, one VAT position to reconcile

Is your ecommerce business local or international?

An ecommerce business selling in several countries and marketplaces faces taxation that has little to do with that of a local business: the OSS scheme, VAT in the EU, VIES, international warehouses, imports and multiple currencies. At ARRA Corporate we manage that complexity.

VAT by country is starting to become a problem
The heart of international ecommerce

VAT and international

OSS, intra-EU VAT, VIES, imports and warehouses outside Spain, including Amazon FBA. All the international tax of your ecommerce business, sorted.

OSS scheme: a single return for the whole EU

You declare VAT on all your sales to EU consumers in one place, applying the rate of each destination country: a single quarterly return in Spain, and the Spanish Tax Agency distributes it.

Intra-EU VAT and VIES

B2B sales between Member States, VAT registrations in other countries when OSS is not enough, and validation of each customer in VIES before invoicing without VAT.

International warehouses and imports (FBA)

Holding stock in another country requires you to register there, even if you sell through the OSS. Imports, exports and inventory movements between logistics centres.

Where the goods are held changes the regime

Your stock determines the tax route

Two diagrams, one essential difference: selling abroad does not create the same obligation as storing goods abroad.

All stock is in Spain

One warehouse supplies consumers in several EU countries.

Sales made within Spain are declared under Spanish domestic VAT.

Your stock is held in several countries

Each warehouse generates local sales and sales to other EU countries.

VATSale in the warehouse countryLocal return

VAT is declared in the same country where the stock is held and the sale takes place.

OSSSale to another EU countryOSS return

Groups together B2C sales shipped from any of the warehouses to another Member State.

With stock in several countries, both obligations apply side by side: local VAT in each country and OSS for cross-border sales.

In one sentence: a warehouse in Spain generates Spanish VAT and OSS for sales abroad; having warehouses in other countries adds a local return in each country where you hold stock, while OSS continues to group cross-border sales.

The countries in the diagram are an example: the real map depends on where you sell and, above all, where you hold stock.

Knowing where you really make money

Decision and control

The overall figure is misleading: a channel can grow in sales while eroding margin, because commissions, logistics and returns do not show up in the selling price. Breaking the data down by channel, country and product turns revenue into a decision: where to invest, where to raise prices and where to pull out.

Method

How we work

We put your international tax operations in order, connect the data from your platforms and turn it into reporting that tells you where you really make money. In that order.

  2. Tax in order

    OSS, VAT registrations and warehouses, regularised and on schedule.

  3. Connected data

    Platforms, payment gateways and accounting, integrated and automated.

  4. Reporting and decision-making

    Dashboard by channel and country, reviewed after every close.
