One-Stop Shop (OSS) is an electronic solution that helps ecommerce stores and online businesses to comply with EU VAT obligations. If you are an online seller or have an ecommerce store, sometimes it can be challenging to comply with VAT obligations in Europe. OSS was established in 2021 to simplify VAT return process for online sellers in Europe. Since its introduction, Business to Consumer (B2C) sellers are not required to register for foreign VAT or to complete VAT filings in countries where they are selling goods.

How OSS simplifies VAT returns process: When you sell products to consumers in different countries, you need to pay VAT in those countries. However, if you have an eCommerce store in EU that engages in cross-border sales of products to consumers, OSS helps you avoid filling VAT returns in multiple countries. It is cumbersome to file tax returns in multiple EU countries. Instead, with OSS, you can just file your VAT returns in one place. For instance, it can be to the home country you are selling from or to a service provider. You, the seller, need to remit the VAT quarterly to your home country’s VAT authority, which will then forward the VAT to the local tax authorities in countries you are selling goods and services. To make it even easier, you can use online service providers such as Taxdoo that can automate these processes for you.

How Does One-Stop Shop VAT Work?

OSS simplifies work and reduces VAT registrations across the EU. It allows sellers to report distance sales (selling via the internet, e-mail or telephone) on a single VAT return in one EU country. This eliminates the need to have multiple VAT registrations across the EU. As such, online marketplaces can declare and pay VAT electronically in one of the EU countries. OSS applies to all business-to-consumer (B2C) sales of goods and services within the EU.

Who Qualifies for OSS? Who Can Use OSS

You qualify for OSS if you are an online seller or a marketplace (electronic interface) in EU. If you qualify, you can register for VAT electronically in a single member state for all sales of goods and services within the EU.

Therefore, you can use OSS if you are:

  • An online seller within the EU. You can use the OSS for supplying goods and services online to consumers within the member states.
  • Online marketplaces. Websites, platforms, and application program interfaces (APIs) can use OSS for facilitating the sell of goods and services to buyers.
  • Non-EU sellers. Sellers who are not EU residents may also use the OSS. They need to register as a ‘non-Union’ taxpayer with the tax authority of any EU member state.
