Invoicing abroad
Invoicing to Belgium: VAT, reverse charge and mandatory details
To a business in Belgium you invoice without VAT and add the reverse-charge note. Your customer accounts for the tax in Belgium; you need their valid VAT ID for that.
This page is written for freelancers and small businesses in Germany and Austria. Pick your country below — the rules differ.
Do you charge VAT?
From Germany to a business in Belgium: no VAT, with the reverse-charge note. The basis is § 3a Abs. 2 in Verbindung mit § 14a Abs. 1 UStG. The standard rate in Belgium is 21 % — but your customer accounts for it, not you.
From Austria to a business in Belgium: no VAT, with the reverse-charge note. The basis is § 3a Abs. 6 UStG 1994 in Verbindung mit Art. 196 MwStSystRL. The standard rate in Belgium is 21 % — but your customer accounts for it, not you.
Private customers: Reverse charge never applies to consumers. Up to €10,000 in total you charge your own domestic VAT; above it you owe the destination country’s VAT and report it through the One-Stop Shop (§ 3a Abs. 5 UStG). Note the €10,000 is cumulative across the whole EU, not per country.
The sentence for the invoice
No exact wording is prescribed; the note only has to be unambiguous. This is the customary form:
Steuerschuldnerschaft des Leistungsempfängers (Reverse Charge)
Both VAT IDs belong on the invoice: yours and your customer’s. Without a valid recipient VAT ID the reverse-charge mechanism does not apply.
Do you have to report it?
Yes. The supply belongs in the recapitulative statement, with your customer’s VAT ID and the net amount — by the 25th day after the end of the reporting period. It is a report rather than a tax return, but it is forgotten regularly, and it is the most common reason a tax office asks about EU supplies.

Does Belgium’s e-invoicing mandate apply to you?
Since 1 January 2026 Belgium requires structured Peppol e-invoices for domestic B2B — binding Belgian taxable persons among themselves. Businesses not established in Belgium and without a fixed establishment are explicitly exempt, even if VAT-registered there. Oddly but genuinely: the Belgian portal expects you to inform your contract partners of that exempt status yourself.
In short: the duty is your customer’s, not yours. You send a normal invoice; they do whatever their own system requires of them.
The most common mistake
If a Belgian client demands a Peppol invoice, that is a contractual request, not a legal duty. You may choose to accommodate it — but you are not obliged to, and Billy cannot.
