What is the OSS procedure?
The OSS (One-Stop-Shop) procedure simplifies VAT processing for online merchants who operate across borders within the EU. Instead of having to register for VAT in each country to which they deliver, merchants can pay VAT centrally through the Federal Central Tax Office (BZSt).
The obligation to register for VAT in a foreign country applies to sales of more than €10,000 in other EU countries.
The €10,000 sales limit applies not to individual countries, but to all EU countries to which goods are shipped to private customers. This means that all deliveries from one EU country to another – for example, from Germany to France and from Germany to Austria – are added together. If a company also maintains a warehouse in another EU country, such as Poland, the deliveries from Poland to Germany are also included in this limit. As a result, the €10,000 threshold is very quickly exceeded, since it applies to all European countries together.
That is why it is so important for online retailers to register for the OSS scheme. Unfortunately, we repeatedly see tax advisors neglecting to register their clients for this scheme in good time – even though there is no reason not to do so. The OSS scheme offers many advantages and makes VAT processing much easier.
Please note: anyone who does not use the OSS procedure must register for VAT in each EU country to which they supply goods. This is often very time-consuming and expensive, as registration can cost several hundred to over a thousand euros. In addition, there are the running costs for meeting the monthly filing deadlines in the respective countries.
Advantages of the OSS procedure
Centralised processing: VAT can be paid in a standardised way via the BZSt, which eliminates the need to register for VAT in each EU country to which goods are delivered.
Simplification: Registration and processing under the OSS procedure is much simpler than the cumbersome registrations and reports in each individual country.
Reporting period: Instead of monthly reports, the OSS report is submitted quarterly, which can lead to a liquidity advantage.
Challenges and limits of the OSS procedure
Despite the numerous advantages, the OSS procedure also presents some challenges:
No retroactive registration: Traders must decide in favour of the OSS procedure in good time, as retroactive registration is not possible. Anyone who crosses the €10,000 threshold should therefore act immediately.
Accounting implementation: Financial accounting becomes more complex when the OSS procedure is used. Transactions must be recorded and exported in a differentiated manner so that they appear correctly in the accounting records.
Limitations of the OSS procedure: Not all business transactions can be processed using the OSS procedure. For example, shipments of goods between the company's own warehouses in different EU countries (e.g. from Poland to Germany in the case of Amazon CEE) must continue to be reported separately.
