Hungary accounting compliance requirements

Hungary runs one of the strictest real-time invoice reporting regimes in the EU through RTIR and the NAV Online Számla platform, requiring nearly all domestic B2B, B2C, and cross-border invoice data to reach the tax authority within minutes of issuance, ahead of a planned move to a full national e-invoicing platform from 2028.

Real-Time Invoice Reporting (RTIR)

Invoice data for domestic transactions must be transmitted electronically and immediately to NAV via the Online Számla platform in XML format.
