VAT Treatment of B2C and B2B Transactions with Simultaneous OSS Use and Local Registration in Austria

Summary
Companies using the OSS procedure for B2C transactions and simultaneously registered for VAT in Austria must continue to report their B2C transactions through the OSS. The local registration for B2B transactions does not affect the OSS reporting obligation for B2C transactions. Dual reporting is not permitted.
Introduction
The introduction of the One-Stop-Shop (OSS) procedure on July 1, 2021, significantly simplified the reporting of cross-border B2C transactions within the EU. Companies can fulfill their VAT obligations centrally through the OSS procedure in their country of establishment. At the same time, companies may be VAT registered in another EU member state, such as Austria, due to B2B transactions. This raises the question of how B2C transactions should be handled in such cases. Find the most relevant questions and answers here.
OSS Procedure and Local Registration
The OSS procedure allows companies to report their B2C transactions centrally without having to register separately in each EU member state. It is important to note that once a company has opted to use the OSS procedure, it is mandatory for all corresponding B2C transactions. Parallel reporting of these transactions in the local VAT return is not permitted.
If a company is additionally VAT-registered in another EU member state, such as Austria, for example due to B2B transactions, this does not affect the reporting of B2C transactions. B2C transactions must continue to be reported exclusively via the OSS procedure. The local VAT registration is used solely for handling B2B transactions and has no impact on the OSS reporting obligation.
Practical Implementation
Companies should ensure that their internal processes clearly distinguish between B2C and B2B transactions. B2C transactions are to be reported through the OSS procedure, while B2B transactions are to be declared in the local VAT return in Austria. Dual reporting of B2C transactions in both the OSS and the local VAT return is not only impermissible but can also lead to tax disadvantages.
It is important for companies to configure their accounting and ERP systems accordingly to ensure correct allocation and reporting of transactions. They should also regularly review whether their processes comply with current legal requirements.
Conclusion
Simultaneous use of the OSS procedure for B2C transactions and local VAT registration in Austria for B2B transactions is possible and legally permissible. However, it is crucial that B2C transactions are reported exclusively through the OSS procedure and do not appear additionally in the local VAT return. Companies should adjust and regularly review their internal processes accordingly to avoid tax risks.
