EU · Real-time invoice-data reporting (RTIR) to NAV Online Számla; sectoral e-invoicing mandates
Hungary requires real-time reporting of invoice data to NAV rather than a general structured e-invoice – comprehensive since 2021 – plus sectoral e-invoicing mandates for energy (2025) and water utilities (2026) and, from 1 Sep 2026, receipt-data reporting (eNyugta).

Two questions. The fixed-establishment rule is where most foreign businesses get it wrong.
Is your business established in Hungary (registered office, branch or fixed establishment)?
Do you issue domestic B2B invoices in Hungary?
Hungary: likely outside the issuing mandate — watch e-reporting / cross-border
VAT registration or trading alone, without a fixed establishment, usually keeps you outside Hungary's issuing obligation — but you may still face e-reporting or need to receive structured e-invoices. Confirm your establishment status.
Not in scope for Hungary
With no establishment and no registration or trade in Hungary, the mandate doesn't apply to you today. Revisit this if you open a branch, warehouse or start supplying into Hungary.
In scope – report invoice data to NAV in real time
Hungary has no general structured e-invoicing mandate. Since 2021 you must report invoice data to NAV in real time (RTIR) in NAV's XML schema. Structured e-invoicing is mandatory only for energy suppliers (since 1 Jul 2025, to non-private customers) and water utilities (since 1 Jan 2026, to non-residential users).
Hungary: no general receive obligation
There is no general obligation for businesses to receive structured e-invoices in Hungary – only public bodies must receive EN 16931 e-invoices, since 1 November 2019.
