Slovenia B2B e-invoicing e-SLOG on pause

2023 earliest implementation date with bill stalled in Parliament

Slovenia’s plans to mandate electronic invoices on B2B transactions remains stalled. The plans were for a pre-clearance model, similar to Italy’s SdI, by draft legislation issued last summer has not progressed out of Parliament following a public consultation.  The draft law indicates a 12-month notice period once the bill is approved, implying no introduction before 2023.

Slovenia was an early adopter for e-invoicing, imposing B2G e-invoices in 2015 and ahead of the 2019 obligation.

Pre-clearance e-invoices e-SLOG

The draft legislation would impose the obligation on all taxpayers for B2B transactions.  This would include a full registration on the PRS business register.

Draft sales invoices would be generated by the vendor in XML. This would be submitted to the tax authorities. This will probably be on the UJP portal under the e-SLOG (Elektronsko poslovanje slovenskega gospodarstva)standard developed for state document exchange to the National registry of recipients of eInvoices. This in turn is now linked to the Peppol network.

Submitting e-Invoices will be submitted to UJP via:

  • manual creation online in the UJP login
  • XML format
  • Direct upload
  • Peppol access point
  • Third-party e-invoicing agent

Following basic live tax validation checks, it would be issued with a unique ID code. The vendor could then issue the invoice directly to their customer who would revalidate with the tax office.
