From 1 January 2027, domestic B2B and B2G invoices in Slovakia must be issued as e-invoices via the Peppol-CTC model. eConnect is a PASR-certified Access Point and supports PINT-SK, TDD SK and the required reporting to Finančná správa.

Slovakia is the first EU country to implement a national B2B mandate fully through Peppol-CTC. Invoice exchange and tax reporting run together over the Peppol network.
In the 5-corner model, both the sender-AP and the receiver-AP send a Tax Data Document Slovakia (TDD SK) to Finančná správa (the Slovak tax authority). The Message Level Response (MLR) confirms that the invoice was correctly delivered — the basis for real-time control.
The mandate applies to domestic B2B and B2G transactions where the supplier or recipient is a Slovak VAT-registered entity. This includes:
- Slovak companies invoicing or receiving domestically
- Dutch and other EU suppliers with Slovak buyers (NL → SK)
- Organisations with an SK entity wanting their ERP and Access Point route production-ready before 2027
Voluntary onboarding and testing is possible in 2026. Recommendation: start well ahead of the deadline so integration, identifiers and testbed validation are in order.
- Determine your scope — which entities and flows fall under the B2B/B2G mandate?
- Choose a PASR-accredited Access Point — without PASR, an AP may not manage a Slovak Peppol address.
- Arrange formats and identifiers — PINT-SK / BIS 3.0, DIČ (EAS 0245) and SK:VAT (EAS 9950).
- Test and onboard in 2026 — use the transition period before 1 January 2027.
- Secure archiving — 10-year retention period (20 years for real estate).

From 1 January 2027 for all domestic B2B and B2G transactions. In 2026, organisations can voluntarily onboard and test with the Finančná správa platform.
Slovakia adds real-time tax reporting via Tax Data Document Slovakia (TDD SK). Invoice exchange and reporting to the tax authority run together over Peppol — the first fully Peppol-based CTC mandate in the EU.
Yes. eConnect supports PINT-SK and Peppol BIS 3.0, routes via Peppol to Slovak recipients and processes the TDD SK reporting. eConnect is a PASR-certified Access Point.
Finančná správa accepts voluntary onboarding and testing in 2026. Recommendation: start well before Q4 2026, so ERP integration, identifiers and testbed validation are in order before 1 January 2027.
From 1 July 2030, the framework extends to cross-border reporting (ViDA-DRR). eConnect is ViDA-ready: the platform architecture supports DRR and EN 16931 with local CIUS extensions.
Besides PASR accreditation for Slovakia, eConnect works according to recognised standards, including ISO 27001, NEN 7510, ISAE 3402 Type II and Peppol Certified Access Point. Data processing takes place within the EU/EEA.
Schedule a no-obligation meeting. We will review your flows (NL → SK or SK → SK), the steps for PASR-compliant connection and what PINT-SK and TDD SK mean for your situation.
