conversation #4821How does the Italian split-payment regime apply to invoices issued to listed entities in 2025?
The split-payment regime (scissione dei pagamenti) applies to supplies made to Italian Public Administration entities and to companies listed on the FTSE MIB index. Per Decreto-Legge 50/2017, Art. 17-ter, the supplier issues the invoice without collecting VAT — the buyer remits VAT directly to the Treasury.
The regime was extended through 30 June 2026 by Council Implementing Decision (EU) 2023/1552.
