Another country takes a step further into realm of digitization. 

Belgium is set to introduce mandatory structured e-invoicing for most B2B transactions from January 1, 2026. This means businesses will need to use Peppol BIS or other EN 16931-compliant formats, eliminating PDFs and paper invoices. 

By 2028, Belgium will take it a step further with near real-time e-reporting for VAT compliance. Businesses will have to transmit transaction data directly to tax authorities, streamlining VAT compliance and reducing fraud. This system is expected to integrate with cash registers, payment systems, and invoicing platforms for automatic reporting. 

Furthermore, as of 2028, Belgium will likely transition from a Peppol 4-corner model to a Peppol 5-corner model (a structure that includes the tax authorities in the process). The Peppol 5-corner model will allow real-time e-reporting, enhancing tax monitoring. This adoption will help combat VAT fraud by ensuring that tax authorities receive up-to-date transactional data, reducing opportunities for tax evasion. 

These changes align with Europe’s digital tax transformation. At InterForm, we recommend our Belgian customers and Belgian businesses begin preparations now to ensure compliance and a smooth transition.
