E-invoicing back on the Belgian political agenda – Plan to introduce B2B mandate on 1 January 2026

The Belgian Finance Minister has relaunched the plan to introduce mandatory e-invoicing for domestic B2B transactions. A pre-draft bill was adopted by the Council of Ministers on 29 September 2023, aiming at an introduction of the e-invoicing obligation as of 1 January 2026. To bring this bill to adoption, the Belgian government will need to obtain a derogation from the European Commission and pass the legislation through Parliament.

Previous proposal

Two important differences we want to highlight compared to the previous e-invoicing pre-draft bill that was part of the tax reform are that:

• there will be no phased implementation, meaning that the mandate would become applicable to all Belgian established VAT registered entities on 1 January 2026 and
• an associated e-reporting obligation is expected to be defined and introduced at a later stage.

B2B e-invoicing

As a short recap, the B2B e-invoicing mandate will:

• apply to taxable persons established in Belgium and Belgian branches of foreign entities. Foreign businesses with a mere VAT registration in Belgium are not envisaged at the moment.
• oblige companies to issue invoices in an electronic structured data format (PEPPOL-BIS) for domestic transactions in Belgium. Parties can agree to use another structured data format as long as it is in line with the European EN16931 standard. Sending a pdf invoice per e-mail will hence no longer be allowed in a domestic B2B context.

Impact

Despite the seemingly distant "big bang" implementation deadline, businesses should begin preparing for this new mandate as soon as possible. Businesses can leverage this e-invoicing obligations as an opportunity to reassess their digital strategy for the future and begin exploring solutions that are tailored to their company's unique requirements. In our experience, the introduction of e-invoicing serves as a catalyst for the transformation and automation of business’ tax and finance processes.
