Slovakia Live

Slovakia is introducing mandatory business-to-business e-invoicing over Peppol, paired with a new national requirement to report tax data on every transaction, starting 1 January 2027. From 1 July 2030, an EU-wide cross-border reporting layer joins on top for trade with other EU countries.

The mandate at a glance

  • VAT-registered businesses trading domestically within Slovakia are in scope from 1 January 2027.
  • From 1 July 2030, intra-EU cross-border transactions are additionally covered under the EU's wider tax-reporting framework (ViDA) — Slovakia is the first EU country to have its own national tax-reporting extension running ahead of that EU-wide layer.
  • The regulatory model mirrors the UAE and Oman's: both the sending and receiving provider independently submit a tax-data document to a dedicated tax-authority access point, operated by Slovakia's Financial Directorate.

How it works

  • Invoices and credit notes use the standard Peppol invoice format (no Slovakia-specific customisation) over the Peppol network.
  • Businesses are identified by their Slovak Tax ID (DIČ). Whether a given invoice also triggers tax-data reporting depends on whether a VAT ID is present on it.
  • Onboarding is mediated by Slovakia's national digital-identity portal — you authenticate there and appoint your chosen Peppol provider.
  • Tax-data reporting happens per transaction, in near-real time, with no periodic batch filing.
