- From January 1, 2027, VAT payers in Slovakia must use structured XML e-invoices (EN16931/UBL) for domestic B2B and B2G transactions via certified intermediaries (“Digital Postmen”) on the Peppol network.
- All legal entities and entrepreneurs, even if not VAT-registered, must be able to receive eFaktúras; B2C invoices are excluded.
- A voluntary transition period runs from January 1, 2026 to January 1, 2027; penalties for non-compliance can reach €10,000–€100,000, but honest, promptly corrected mistakes are exempt.
- The Slovak Financial Directorate is the national Peppol Authority, accrediting service providers and overseeing the network.
- The VAT control summary report will be abolished from July 1, 2030, as invoice data will be reported automatically; cross-border e-invoicing is planned under the EU ViDA initiative around 2030.
