Frequently asked questions
01Is e-invoicing mandatory in Slovenia?
For suppliers to public-sector budget users, yes - since 1 January 2015, through the PPA/UJP system. For domestic B2B, the ZIERDED act adopted in October 2025 makes structured e-invoicing mandatory from 1 January 2028 for businesses registered in Slovenia and sole proprietors.
02Can I email PDF invoices to Slovenian businesses after 2028?
No. Under ZIERDED a PDF is not an e-invoice, and email is expressly not a permitted exchange method for regulated domestic B2B. Invoices must be structured documents exchanged via a registered provider, the Peppol network, or a direct connection.
03What format do Slovenian e-invoices use?
e-SLOG 2.0 is the national default standard and is aligned with EN 16931. EN 16931-compliant syntaxes such as Peppol BIS Billing 3.0 are also permitted, and other standards may be used where both parties agree in advance.
04Does Slovenia report invoices to the tax authority?
No. Slovenia is not a clearance country: ZIERDED explicitly does not introduce reporting of exchanged e-invoices to FURS. Periodic VAT returns and VAT ledgers via eDavki remain a separate obligation from invoice exchange.
