If you are a franchisee in Belgium under the small business exemption scheme, you must now submit a nil annual client listing via Intervat, even if you have no B2B clients to declare.
Until recently, companies benefiting from this regime did not always have to submit an annual client listing when it was nil, meaning they had no clients to declare.
🚨 Starting in 2026, this changes: even if your client listing is empty, you must now submit a “nil” listing via Intervat.
Companies under this regime must also communicate their total turnover realised in Belgium during the previous calendar year.
📅 For operations carried out in 2025, the filing deadline is 31 March 2026.
An annual client listing only concerns B2B clients with a Belgian VAT number to whom you invoiced more than €250 excluding VAT during the year.
⚠️ If you have no such clients, your listing is "nil". You must still submit it via Intervat and indicate your annual turnover (or €0 if you carried out no operations).
