I notice that you do not include non-deductible vAT on, for example, restaurant costs, car expenses, etc. in box 82. The amounts to be entered in boxes 81, 82 and 83 must be increased by the amount of non-deductible vAT insofar as this vAT relates to the economic activity of the declarant. Example: purchase of a passenger car in Belgium for an amount of EUR 25,000 (+ vAT EUR 5,250). Private use: 30% (the non-deductible vAT relating to the economic activity of the declarant amounts to 20%, taking into account the restriction imposed by Article 45, § 2, first paragraph, of the vAT Code). Schedule 83: 70% from 25,000 + 20% from 5,250 = EUR 18,550.00Schedule 59: 50% from 5,250 = EUR 2,625.00 (point 161 of the vAT declaration explanation).
