Regulated by the Hungarian National Tax and Customs Administration (NAV). Real-time invoice reporting requirements aim to reduce VAT fraud and improve transparency.
Implementation of mandatory e-invoicing in Hungary

Hungary’s e-invoicing system focuses on real-time invoice reporting rather than structured Peppol-style exchange:
- Since July 2018, all domestic B2B invoices with VAT must be reported to the NAV Online Invoice System. Invoices are issued through any invoicing software, then submitted digitally to the tax authority.
- By 2021, Hungary extended the requirement to all transactions, including B2C, exports, and cross-border deals.
