Italian credit notes and VAT adjustments: correcting an invoice and recovering unpaid VAT
Article 26 of Presidential Decree 633/1972 applied to everyday cases: compulsory upward adjustments, credit notes for returns, terminations and contractual discounts, the one-year limit on later agreements, what the customer must record and why the SdI rejects some notes. Then unpaid invoices: insolvency proceedings opened from 26 May 2021, fruitless enforcement, and dividends received after the note. Two modules with case studies, 2026 rules.
