Belgium 120% Tax Deduction for E-Invoicing: Eligibility, Claims & Documentation

Belgium incentivizes e-invoicing adoption with a 120% tax deduction on implementation costs, effectively subsidizing the transition for businesses of all sizes. Introduced alongside the B2B e-invoicing mandate, this measure allows Belgian companies and self-employed workers to deduct 120% of qualifying e-invoicing expenses from their taxable income. For a business paying a 25% corporate tax rate, this means every €1,000 spent on e-invoicing yields a €300 tax saving (compared to €250 for a normal 100% deduction).

What Costs Qualify for the 120% Deduction?

The increased deduction applies to investments directly related to achieving e-invoicing compliance:

The increased deduction applies to investments directly related to achieving e-invoicing compliance:

• Software costs: E-invoicing software licenses, subscriptions, or upgrades to PEPPOL-compatible versions.
• Access Point fees: PEPPOL Access Point subscriptions and setup costs.
• Integration costs: Development or consulting fees for connecting your accounting/ERP system to PEPPOL.
• Training costs: Staff training on e-invoicing workflows and software usage.
• Hardware: IT infrastructure upgrades specifically required for e-invoicing (e.g., server capacity).

What Costs Do NOT Qualify?

General accounting software not specifically related to e-invoicing. Pre-existing software licenses that were already in use before the mandate.

The claim process follows standard Belgian tax deduction procedures:

1. Collect invoices: Keep all invoices from e-invoicing service providers (software vendors, Access Points, consultants).
2. Document the purpose: Each expense should clearly relate to e-invoicing compliance—add notes referencing the PEPPOL mandate.
3. Apply the 120% rate: In your corporate tax return (form 275.1) or personal income tax return (Part 2), declare the expenses at 120% of the invoiced amount.
4. Retain documentation: Keep all supporting documents for at least 7 years (standard Belgian retention period).

The extra 20% deduction provides an additional €380 in tax savings in this example, on top of the normal deduction benefit.

Is the 120% Deduction Available to Self-Employed Workers?

Yes.

Yes. Belgian self-employed workers (zelfstandigen/indépendants) can claim the 120% deduction on their personal income tax return. The same qualifying expenses apply—software, Access Point fees, training, and integration costs. Given that self-employed workers often have simpler setups, their costs are typically lower, making affordable solutions like Invoicemonk with built-in PEPPOL support especially cost-effective.
