2021 is a year characterized by many new developments for businesses, in the tax field, and by further changes to the electronic invoice layout. In fact, on January 1st, new technical specifications for the XML layouts of the e-invoice came into force: some of these specifications were introduced directly by the producers of software and platforms for the web invoicing, others will have to be entered manually.
The new technical specifications introduced are the only ones accepted by the Interchange System and the new XML path has been updated to version 1.6.1. What changes for taxpayers and how should the software be adapted to the new regulations in the invoicing field?
Il web invoicing program includes within it numerous standard and additional fields for electronic invoicing, which allows each type of company to insert specific types of exemptions, VAT rates and mandatory wording to be included in the invoice. Below we will see what the new XML path consists of and what are the innovations introduced in the software for the web invoicing.
Web Invoicing: How the New Path Works and Technical Specifications 1.6.1
The new technical specifications introduced by the Revenue Agency outline a new version of the electronic invoice record tracks with new codes to be implemented within the software for the web invoicing to have the document approved by the Interchange System.
The new codes concern two particular fields of the electronic invoice: the type of document and the nature of the operation. Among the new features introduced we also find the field "amount" relating to the stamp duty which becomes optional: in invoices with payment of the stamp duty, the field "stamp duty data" can be completed without specifying the relative amount.
The new technical specifications allow you to also include social security withholdings in the invoice, choosing between the following codes:
- RT01 and RT02, for natural and legal persons;
- RT03 and RT04, for INPS contribution and Enasarco contribution;
- RT05, for Enpam contribution;
- RT06, for other social security contributions.
