VAT by the 25th
Monthly filers are on the 20th, quarterly filers on the 25th, and since 1 January 2026 the Belgian business to business purchase side largely arrives over Peppol. What is left over is precisely what does not: the client who never hands in the costs he paid privately, the supplier whose Peppol address is still not sorted, the fuel invoice in the company name that was never sent through. We line that up file by file and put the reminder email ready in the wording your firm always uses.
