Cross-border business: Belgium as a European hub
Belgium is ideally located for cross-border trade. Discover the advantages, intra-community VAT obligations and steps to operate in the EU.
In brief
Belgium is the ideal European hub for cross-border businesses: three land borders, the second-largest European port and Brussels as the EU capital provide direct access to 450 million consumers in the single market. Intra-community VAT obligations (reverse charge for B2B, OSS regime for B2C) apply from the first sale in another member state. Mastering these rules and verifying business partners via the BCE is the foundation of a successful internationalisation strategy from Belgium.

Frequently asked questions
Is Belgium a good country for cross-border trade in Europe ?
Yes. Belgium borders France, the Netherlands, and Germany, hosts the second-largest European port (Antwerp-Bruges), and is home to EU institutions in Brussels. From Belgium, you access all 27 EU member states without customs formalities, reaching 450 million consumers. Its trilingual workforce and tax treaties with over 95 countries reinforce this advantage.
How does intra-community VAT work for B2B sales from Belgium ?
For B2B sales, when your European customer holds a valid VAT number (verifiable via the VIES system), the reverse charge mechanism applies: you issue an invoice excluding VAT with the mandatory legal statement, and the customer declares VAT in their own country. You must report these sales in a quarterly intra-community listing filed with the Belgian FPS Finance.
What is the OSS regime and when does it apply to B2C sales from Belgium ?
The OSS (One-Stop-Shop) is a European single window for declaring VAT on cross-border B2C sales. It applies once your total B2C sales to other EU countries exceed 10,000 euros per year. Below that threshold, you apply Belgian VAT. Above it, you charge the destination country's VAT rate and report it through the OSS portal.
How can you verify a foreign or Belgian business partner before a cross-border transaction ?
For a Belgian partner, use the Company Belgium API which directly queries the BCE/KBO database: you get the active or inactive status, legal form, registered address, and NACE codes within seconds. For partners from other EU countries, use the European Commission's VIES system to validate the VAT number and registered company name.
