Hungary's tax authority to mandate receipt data reporting from Sept 2026

Effective 1 September 2026 the National Tax and Customs Administration (NAV) will require businesses that issue hand‑written or computer‑generated receipts to submit receipt data to NAV within three calendar days. The data must be sent as a daily aggregate broken down by tax rate through NAV’s electronic portal, not as individual entries. The rule applies to firms that do not use online cash‑registers, which automatically transmit the information. Industry experts estimate that 5,000‑10,000 entrepreneurs and primary producers, especially in Bács‑Kiskun County, will be affected. The change aims to further digitalise tax processes and increase transparency. Businesses using online or e‑cash registers are exempt, as their systems already report required data automatically. NAV plans to issue detailed guidance and an electronic submission interface to help affected firms prepare for the new requirement.
