1. Operation-by-operation margin (default regime)
VAT calculation for each sale individually, with no offsetting between transactions.
- Formula — VAT due = (VAT-inclusive sale price − purchase price) × 20 / 120
- Negative margin — no VAT due (margin ≤ 0), but no offsetting against other transactions
- No formality — regime applicable as of right, with no option to be filed
- No commitment — the dealer may switch to the global margin at any time
