Belgium: Mandatory e-invoicing rollout by 2026

Belgium will introduce mandatory electronic invoicing from 1 January 2026 to reduce VAT fraud, which is estimated at 2.5 billion euros per year. Currently, 85% of all Belgian invoices are still sent in paper form or as PDF attachments in emails (source: PwC at 2024 Tax Compliance Virtual Symposium), formats that will no longer be permitted after this deadline.

What will change?
From 1st of January 2026, all VAT-registered taxpayers established in Belgium will be required to issue and receive structured e-invoices. In addition, non-established foreign taxpayers with a VAT-registration in Belgium will be required to receive e-invoices.

PEPPOL’s 4-Corner Model as the Standard
PEPPOL’s 4 corner model will become the default framework for invoice exchange. Deviation from using this framework will be possible, however, agreement from both parties will be required. Taxpayers in scope will be obliged to exchange structured e-invoices following European EN 16931 standards. That means a PDF via email will not be considered an electronic invoice and will not be allowed for taxpayers in scope.

Future plans: Real-time reporting
After rolling out mandatory exchange of electronic invoices between partners, Belgium plans to introduce real-time reporting aiming for a 5 or six corner model via PEPPOL. Then tax relevant information will be reported to tax authority as well. However, it is only the e-Invoicing obligation to be implemented January 1, 2026.

Big bang rollout: No gradual implementation 
Interestingly, Belgium has opted for a “big bang” rollout, meaning that every company, whether large or small, will be affected by the mandate simultaneously. There will be no gradual implementation, as is planned in countries like France. Depending on company size though, there are benefits from the Belgium government, such as direct tax incentives to reduce cost of implementation.
