NEW DEVELOPMENTS IN THE FIELD OF ELECTRONIC INVOICE EXCHANGE BROUGHT BY THE ACT ON THE EXCHANGE OF ELECTRONIC INVOICES AND OTHER ELECTRONIC DOCUMENTS
On 1 January 2028, the Act on the Exchange of Electronic Invoices and Other Electronic Documents will come into force in Slovenia. This Act transposes Council Directive (EU) 2025/516/EU from 11 March 2025, amending Directive 2006/112/EC as regards the VAT rules for the digital age into legal order of the Republic of Slovenia. The most notable effects of the new Act are as follows:
Mandatory exchange of electronic invoices between business entities
The Act introduces mandatory electronic invoicing for all business entities entered in the Slovenian Business Register and for natural persons engaged in the supply of goods and services in Slovenia.
This means that from 1 January 2028, the use of e-invoices will be mandatory not only for the public Budget Users and public procurement contractors, but also for all Slovenian companies in the case of business-to-business (B2B) transactions. Paper invoices will still be permitted for business-to-consumer (B2C) transactions and transactions with foreign companies.
Arrangements for consumers
The Act does not introduce any changes for consumers, as companies will continue to issue paper invoices unless consumers agree with companies to issue invoices in electronic form. Consumers will also have the right to withdraw their consent to receive e-invoices.
Possible ways of exchanging e-invoices
An e-invoice is a structured electronic document in XML format, which enables complete automation of business operations. An invoice in PDF format is not recognized as an e-invoice. According to the Law on Mandatory Exchange of Electronic Invoices, visualization of e-invoices is only mandatory for consumers. The Act also stipulates that the exchange of e-invoices will be decentralized and will take place in four ways, namely via:
- E-path providers
- Own systems for direct exchange
- The international PEPPOL network
- The free miniCheckout application for entities with a smaller volume of business
All the above methods of exchange will be conducted via secure electronic channels, therefore sending via email will not be permitted, except when the recipient of the invoice is a natural person consumer.
It is also worth noting that the Act on the Mandatory Exchange of Electronic Invoices and Other Electronic Documents does not provide for reporting exchanged e-invoices to the Financial Administration of the Republic of Slovenia. The method of confirming cash invoices therefore remains unchanged, as the Act does not interfere with the provisions of the Fiscal Verification of Invoices Act. Only the form of the invoice is changing from paper to electronic.
Exchange of e-documents
The adopted Act on the Exchange of Electronic Invoices and Other Electronic Documents does not prescribe the mandatory exchange of e-documents, but it does set standards and methods of exchange if companies decide to use it. Such documents include e-purchase orders, e-delivery notes, e-reminders, and e-IOPs (statements of open items).
