Hungary Introduces Stricter Invoice Data Reporting Rules with Million Forint Penalties

• Hungarian National Tax and Customs Administration introduces stricter conditions for invoice data reporting starting September 15, 2025, replacing simple warnings with error messages that cause submission failures and potential penalties up to one million forints
• The measure applies exclusively to companies using invoicing software connected to NAV online invoice reporting system, requiring software adaptation to meet clarified requirements for improved data accuracy and eVAT service efficiency
• NAV provides a testing environment for businesses and developers to verify compliance risk free, with refinements based on feedback showing significant improvement from 1.2 million rejected invoices in January 2025 to 75,000 by July
• Stricter rules do not affect retailers using only cash registers or online cash registers for end consumer sales, as these systems already report data in real time under separate framework, and users of NAV free Online Invoicing application remain unaffected
• Impact is limited to businesses issuing invoices outside cash registers with electronic reporting requirements, while retailers using only online cash registers can continue unchanged operations but invoice issuing companies must update software before deadline
