E-invoicing in Belgium is more relevant than ever. The country’s electronic invoicing mandate is set to take effect January 2026, when businesses will be required to begin e-invoicing for B2B transactions.
However, many companies still need to become compliant. If your organization isn’t ready, or if you’d like to understand the background of the mandate, this blog post is for you.
In this post, we will explore the current state of e-invoicing in Belgium; details of the upcoming mandate, including a timeline and compliance requirements; how Storecove can support e-invoicing implementation, and more.
Let’s jump in.
Current Status of E-invoicing in Belgium
E-invoicing is not yet mandatory for B2B transactions in Belgium, although this will change in January 2026.
However, it’s a different story for B2G transactions. Since March 2024, e-invoicing has been required for all public contracts. B2G e-invoices must be sent through the Peppol open exchange network using the Peppol BIS 3.0 format.
It is not mandatory to use e-invoicing in B2C transactions, and no mandates have been announced. However, digitization is still encouraged.

Belgium’s New E-invoicing Mandate
E-invoicing will become mandatory in Belgium on January 1, 2026. Companies will be required to use the Peppol network to transmit e-invoices. In 2028, the mandate will expand to include e-reporting. As of January 2028, businesses must digitally submit information to the tax authority.
The mandate serves multiple purposes. It will cut down on VAT fraud, thanks to increased transparency throughout the transaction process, while modernizing Belgium’s invoice and tax systems. With e-invoicing, businesses will be more efficient and their invoicing workflows will become internationally compatible. Additionally, Belgium’s upcoming e-invoicing mandate will prepare the country for VAT in the Digital Age (ViDA), the EU’s initiative to digitize the VAT system.
Countries in the EU must align their e-invoicing systems with ViDA’s formatting and e-reporting requirements by January 2035, but companies must be capable of sending and receiving intra-EU invoices in ViDA-compliant formats by July 2030.
Belgium’s upcoming mandate aligns the country’s e-invoicing system with ViDA’s requirements, ensuring compliance as the initiative goes into effect.

Compliance Requirements
It will be required to use the Peppol open exchange network when transmitting e-invoices in Belgium.
Peppol is an open exchange network created to facilitate the efficient and secure transmission of electronic business documents. Peppol was launched in 2012 by the OpenPeppol organization and remains a leading framework for e-invoice exchange. It is a globally-compatible network, but has the most use in Europe and Asia.
Peppol is based on a 4 corner model. In this framework, the e-invoice sender, receiver, and their respective access points each act as a corner. E-invoices are directly transmitted from the sender to the receiver via their access points. This method is highly secure: All Peppol Access Points must comply with certain data security requirements to become certified.
Belgium’s e-invoicing system will initially be based on this Peppol 4 corner model. This will change with the implementation of Belgium’s e-reporting requirement in 2028, when the country’s e-invoicing system will shift to a 5 corner model. The only difference between the 4 and 5 corner models is the addition of a tax authority to the system. In the 5 corner model, the sender’s access point will submit the e-invoice to the relevant tax authority for validation.
Transitioning to e-invoicing can require changes to a company’s accounts payable systems. To offset some of the costs associated with e-invoicing implementation, the government will offer a temporary increase in deductible expenses. Until 2027, businesses can benefit from a tax deduction of 120% on their e-invoicing expenses.
If businesses do not comply with Belgium’s upcoming mandate, they will be fined. The scale ranges from €1,500 for the first offense, €3,000 for the second offense, and €5,000 for the third offense.
