E-Invoicing in Slovakia

Slovakia is actively advancing its digital tax infrastructure. Evolving from an optional framework into a rigorous statutory mandate, the Slovak government has implemented Law No. 385/2025 Z.z. to enforce mandatory electronic invoicing and simultaneous tax data reporting across both Business-to-Business (B2B) and Business-to-Government (B2G) transactions.

With strict deadlines approaching, persisting with legacy PDF invoices for commercial partners or relying on the retiring IS EFA portal for government billing will soon lead to severe financial penalties and substantial disruption to business operations. To allow enterprises sufficient time to upgrade their ERP and accounting systems to comply with the new unified Peppol standard, the Slovak Ministry of Finance has organized the implementation into two critical milestones:

• 1 January 2027: All VAT-registered businesses established in Slovakia must issue, transmit, and receive structured e-invoices for all domestic B2B and B2G transactions. Whether billing a commercial partner or a government entity, every transaction must be routed through an accredited Service Provider and accompanied by near real-time e-reporting (SK TDD) to the Financial Administration.

• 1 July 2030: All in-scope entities must extend their digital invoicing and reporting capabilities to encompass intra-EU cross-border transactions, ensuring strict alignment with the European ViDA directive.
