If you’re responsible for tax compliance, ERP architecture, or financial reporting in a business operating in Belgium, the next 12 to 18 months could redefine how you work. Starting January 1, 2026, Belgium will require structured e-invoices for all domestic B2B transactions. That’s right, no more PDFs, no more manual email chains, and no more loosely defined formats for domestic B2B transactions, and expected to extend to B2C and cross-border transactions in the near future.”
And it doesn’t stop there. By 2028, businesses must be able to submit invoice data to the Belgian tax authority in near real-time. This isn’t just a tech upgrade. It’s a change in compliance philosophy—one that demands immediate attention.
The Timeline Snapshot
| Mandate | Applicability | Effective From | Format & Requirements |
| Mandatory B2B e-Invoicing | To all taxpayers | January 1, 2026(Original 2025 proposal shifted) | PEPPOL BIS 3.0, XML-based structured e-invoice, via certified access points |
| e-Reporting (Digital VAT Reporting) | To be implemented in the near future | Date under finalization | Real-time/periodic invoice data sharing with the tax authority |
Note: The initial implementation for large taxpayers has been postponed to 2026, offering additional preparation time but increasing urgency for digital transformation in 2025.
Why Now: The Bigger Picture Behind Belgium’s Mandate
This isn’t just a local decision. Belgium is aligning itself with ViDA—the European Commission’s “VAT in the Digital Age” plan. ViDA is designed to reduce fraud, enhance cross-border transparency, and harmonize compliance across the EU.
Countries like France, Germany, and the Netherlands are already underway. Belgium is next in line, and if you’re not thinking regionally, you’re already behind.
“ViDA isn’t just about digital invoices. It’s about removing friction between tax systems and improving enforcement across borders,” says a VAT specialist from Antwerp.
What’s Changing in Belgium?
Structured e-Invoicing Is Mandatory from January 2026
The government will require that all VAT-registered Belgian businesses issue and receive invoices in Peppol BIS 3.0 format via a certified Peppol Access Point. This move builds on Belgium’s existing use of Peppol in B2G transactions.
PDFs, Word docs, and scanned invoices will no longer be legally valid for domestic B2B transactions after December 31, 2025.
VAT Refund Reform Kicks in from Jan 2025
Starting a year earlier, companies will benefit from monthly VAT refunds without the need for prior approval—provided they comply with the digital invoice format and the refund request meets a minimum credit threshold of €50 and the previous six VAT returns were submitted on time.
This is a major win for cash flow, but only if you’re already compliant.
Real-Time Reporting Follows in 2028
By January 1, 2028, Belgium will implement near real-time e-reporting, replacing the outdated Annual Sales Listing (ASL). Businesses will be required to report invoices digitally and immediately, possibly via a 5-corner Peppol model, similar to what’s being explored in Germany.
Penalties? Expect €1,500 for initial non-compliance €3000 for second non-compliance, escalating to €5,000 or 200% of undeclared VAT for repeat offenders or fraudulent e-invoicing practice.
Financial Incentives: Real Money on the Table
To support the transition, Belgium is offering:
- 20% digital investment deduction starting Jan 2025, applicable to software purchases like e-invoicing tools.
- 120% enhanced expense deduction between 2024 and 2027 for smaller businesses (turnover under €11.25 million) investing in invoicing software.
If you’re upgrading ERP systems or onboarding Peppol integrations, this is the time to do it.
Context Matters: Belgium is not alone
This isn’t happening in isolation. Belgium’s neighbors are already building their own frameworks:
- France is phasing in mandatory B2B e-invoicing via the Chorus Pro platform through 2025.
- Germany begins piloting in 2025, with full rollout expected by 2028.
- The Netherlands has already embraced Peppol for public and private sector use.
What does this mean for you? If your business operates across borders, you’ll need a solution that doesn’t just work in Belgium—but across the EU.
Dual Compliance Challenges for Decision Makers
It’s not just about generating an invoice. It’s about developing the correct format, sending it to the right parties, validating tax data, and retaining it properly. All in real-time.
1. Technological Alignment
ERP integrators face a critical task:
- System Integration: Your platforms must support Peppol BIS 3.0 and EN 16931, integrating with VAT platforms for real-time compliance
- Data Accuracy: With various mandatory fields, clean master data across countries is essential to avoid penalties.
- Scalability: Solutions must cover 2026 e-invoicing, 2028 e-reporting, and future ViDA mandates.
2. Operational and Cross-Border Coordination
CFOs and tax heads must lead the charge:
- Process Overhaul: Redesign workflows to merge e-invoicing and VAT
- Stakeholder Sync: Align suppliers and clients across Belgium, France, and beyond for Peppol readiness
- Global Training: Equip teams with Peppol and ViDA expertise to ensure consistency, reducing risks of missed deadlines.
Real-World Scenario: A Pharma Company With 4 ERPs
One Belgium-based pharmaceutical firm operating across BE, FR, and DE deployed a compliance platform. Their pain points:
- Inconsistent invoice data across SAP, Oracle, and Dynamics
- Non-aligned tax codes and VAT rates across countries
- Lack of real-time visibility into invoice status or mismatch errors
