Implementation of mandatory e-invoicing in Slovakia

• January 2022: The Ministry of Finance of the Slovak Republic initiated a pilot phase of the IS EFA (Informačný systém elektronickej fakturácie) platform — Slovakia’s national e-invoicing system. The testing phase focused on developing the technical framework and integration capabilities for e-invoice exchange.
• April 2023: B2G e-invoicing became mandatory. All suppliers issuing invoices to Slovak public institutions are required to submit them via the IS EFA system, in a structured XML format. This step aligns Slovakia with EU Directive 2014/55/EU on electronic invoicing in public procurement.
• Planned next steps: The Slovak government has confirmed its intent to expand mandatory e-invoicing to B2B and B2C transactions, although no specific timeline has been officially announced. The goal is to build a fully digital invoice ecosystem to enhance VAT traceability, reduce fraud, and streamline reporting. Businesses are encouraged to prepare in advance by integrating IS EFA-compatible systems.

• Exporters: Required for cross-border transactions involving VAT reporting within the EU.
