Do I need EU OSS?

The One-Stop-Shop confuses almost every foreign seller. Answer three questions for a clear verdict: whether you need Union OSS, whether Germany is your filing country, and what it costs.

1. Where is your company established?
2. Where do you hold stock / fulfil orders from?
3. Do you sell to consumers (B2C) in other EU countries, beyond Germany?

What the One-Stop-Shop actually is

OSS (One-Stop-Shop) lets you report cross-border B2C sales to consumers across the EU in a single quarterly return, instead of registering for VAT in every country you sell to. It applies once your goods are already inside the EU (for example, shipped from a German warehouse) and you sell B2C across borders.

For the full picture, see our OSS for German VAT guide.

Frequently asked questions

Do I need OSS for Amazon FBA in Germany?

Only for your cross-border B2C sales. German stock selling to German consumers goes on your normal German VAT return; selling B2C to consumers in other EU countries is what Union OSS covers. B2B sales never need OSS. As a non-EU company with German stock, Germany is your Member State of Identification.

Is OSS the same as iOSS?

No. Union OSS covers B2C sales of goods already inside the EU (e.g. shipped from a German warehouse). Import OSS (iOSS) is a separate scheme for goods imported from outside the EU at or under €150. Vaytax files Union OSS as an add-on; Vaytax does not file iOSS.

How much does OSS cost with Vaytax?

For non-EU sellers whose filing country is Germany, OSS is an add-on to the German VAT service: €250 one-time setup plus €150 per quarter. It is never sold on its own, because OSS needs an underlying German VAT registration.

Can a non-EU company use OSS through Germany?

Yes. A non-EU company holding stock in Germany can use Union OSS with Germany as its Member State of Identification, so one quarterly return covers cross-border B2C sales to all EU countries.
