Hungary’s most immediate fiscalization deadline is not 2028. From 1 September 2026, data from manual receipts and receipts generated by computer systems must also be reported electronically to NAV.
The electronic cash-register regulation has been in force since April 2025, and approved electronic cash registers have been available since July 2025.
Existing online cash registers may continue operating during the transition, but businesses currently required to use them will generally have to move to approved hardware-based electronic cash registers by 1 July 2028.
The September 2026 reporting obligation creates the nearer operational challenge.
Businesses that still issue manual receipts or use computer-generated receipts outside an online cash-register system will need a process to submit the data, generally within three calendar days and summarised by day and VAT rate.
Businesses using electronic cash registers will meet this obligation automatically because the required receipt data is sent directly to NAV.
For retailers, this affects more than the receipt itself. POS and accounting systems must classify data correctly, produce the required daily summaries and preserve consistency between the original sale, the receipt and the information transmitted to the tax authority.
A weak manual workaround may create gaps that are difficult to reconcile later.
Retailers and solution providers should identify every receipt flow outside the current online cash-register environment, define who is responsible for reporting and test the complete data path before 1 September.
