ITA - Fattura elettronica - Integrazione ritenuta

This is a bridge module that connects Italian electronic invoice generation with withholding taxes. When you generate the XML file for an electronic invoice, the module automatically adds the withholding tax information that would otherwise be missing.

• It fills the withholding tax block (DatiRitenuta) for each withholding line on the invoice, including the type of withholding, the amount, the rate and the payment reason code.
• It determines the withholding type automatically: professional withholding for individuals, company withholding for companies, and specific codes for social security funds such as INPS, ENASARCO and ENPAM.
• It fills the social security fund block (DatiCassaPrevidenziale) for withholding lines marked to be included there, with the fund type, rate, contribution amount and VAT nature.
• It marks invoice lines subject to withholding with a flag in the XML.
• It adjusts payment amounts in the XML so they match the net amount after withholding.

The module works in the background when exporting electronic invoices and does not add new menus or screens. It extends the existing electronic invoice export wizard and the XML templates used to build the file.
