Hungary's tax authority offers four‑month transition for new receipt‑data reporting from September 2026

From 1 September 2026 the Hungarian National Tax and Customs Administration (NAV) will require all businesses to submit electronic receipt data to the tax authority. The data must be sent within three calendar days of each receipt, aggregated daily by tax rate.

NAV has introduced a four‑month grace period (1 September – 31 December 2026) during which no penalties will be imposed. To help firms comply, NAV offers a free e‑cash‑register application (ePénztárgép) that can automatically transmit the required data, as well as a simple web portal for manual entry and a machine‑interface option for larger merchants.

After 1 January 2027, non‑compliance will be penalised. Companies are advised to review their sales, invoicing and accounting processes now, as the change may affect bookkeeping, tax handling, internal controls and responsibility for data submission.
