Slovenia has proposed mandatory e-invoice reporting for B2B transactions starting 1 June 2026. This will require structured e-invoices to be reported to the tax administration within eight days. B2B invoices with non-residents must also comply, while B2C invoices can remain in paper format. The draft bill is now with the National Assembly for review. This is in line with the EU plans for mandatory e-invoice exchange and reporting for intra-community supplies from July 2030.

Both issuers and customers must report e-invoice exchanges to the Financial Administrator (FURS) within eight days, with no pre-clearance needed. Taxpayers can use three formats for e-invoices: the e-SLOG national standard, the EN 16931 EU standard, or an internationally recognized format agreed upon by both parties. Registered service providers or 'e-route' providers can facilitate the exchange.
Slovenia, an early adopter of e-invoicing, has used the e-SLOG standard since 2015. The draft law would require all taxpayers to register on the PRS business register and submit sales invoices in XML format to the tax authorities within eight days, likely via the UJP portal linked to the Peppol network. E-invoices can be submitted to UJP through manual creation online, XML format, direct upload, Peppol access point, or third-party e-invoicing agents.
