Slovakia is entering a new era of digital tax compliance. From 1 January 2027, domestic VAT-registered businesses will be required to issue structured electronic invoices for in-scope domestic B2B and B2G transactions while supporting tax data reporting through the Slovak Tax Data Document (TDD). The reform is built on a Peppol-based delivery model and introduces new technical, operational, and reporting obligations for businesses operating in Slovakia.
Our free Slovakia e-Book explains what these changes mean in practice and how organizations can prepare their ERP systems, processes, and compliance strategy before the mandate becomes mandatory.
