Hungary requires NAV-connected e-receipt registers from September 2026 — 270,000 businesses pulled in.
HUF 6,000 (~€15). That is the cheapest way for a Hungarian shop owner to stay legal on 1 September 2026 — a thermal receipt printer, before a roll of paper, before a line of cloud-app code. From that morning every beautician, hairdresser, estate agent and market trader handing a customer a receipt has to run a NAV (Nemzeti Adó- és Vámhivatal — Hungary's tax authority)-connected ePénztárgép (e-cash register) and stream each sale to the state in real time. About 270,000 businesses are in scope. The Treasury has booked HUF 10–20 billion (~€25–50 million) a year of shadow-economy revenue against the rollout.1,2
01The pain
The beautician in Pécs has run her till on a paper receipt booklet for fifteen years. The hairdresser in Szeged inherited the same booklet from his mother. Neither has ever opened a NAV (Hungary's tax authority) portal. On 1 September 2026 both wake up illegal. The paper booklet is finished; the 2013-vintage online cash register has a longer fuse — fully phased out by 1 July 2028 — but it is finished too. VATupdate, the trade outlet that tracks every NAV release Hungarian shops eventually have to live with, lists the cohorts swept in for the first time: beauticians, hairdressers, estate agents, market traders, and the long tail of cafés on legacy tills. None were touched by the 2013 wave. All now meet a tax-authority API as a first event.1
The scale turns this from a digitisation footnote into a fiscal program. About 270,000 businesses in scope. HUF 10–20 billion (~€25–50 million) a year of shadow-economy revenue already booked against the rollout. A printer floor of roughly HUF 6,000 (~€15) before consumables, then either NAV's own ePénztárgép (e-cash-register) cloud app or a new-generation register from a private vendor. The Treasury's framing is HUF 10 (~€0.025) saved per receipt. Helpers Finance, a Budapest corporate-services firm with a heavy small-business book, makes the obvious point: that saving only arrives after the printer, the app and the workflow rebuild have all been paid for first.2 A once-a-year accounting event becomes a daily compliance task.3
State Secretary Bence Gerlaki put the official line into Hungarian Conservative in plain words: the paper-based receipt is "outdated both technologically and administratively." NAV's penalty schedule does not draw a line between the shop that never integrated and the shop whose connected register failed to transmit on time. Both are late. Both pay. The beautician in Pécs is not joining a digital state — she is being told that a workflow that worked for fifteen years stops being legal in September.4
02Who solves this today
Two Hungarian vendors openly self-market into the ePénztárgép / e-nyugta (e-receipt) / NAV-pénztárgép niche on their own Hungarian-language pages — one cloud-invoicing platform, one pénztárgép (cash-register) manufacturer. NAV's own ePénztárgép cloud app is the regulator's reference implementation, cited in section 01, not listed here. The list is intentionally narrow.
Listed providers publicly market to the Hungarian ePénztárgép / e-nyugta (e-receipt) / NAV-pénztárgép / online pénztárgép (online cash-register) niche on their own homepages or canonical Hungarian-language product pages. Inclusion is not endorsement. Adjacent Hungarian or HU-active invoicing/POS vendors were considered and excluded where their public homepage did not explicitly name the ePénztárgép / e-nyugta / NAV-pénztárgép niche at the date of writing — Billingo's homepage names "Billingo Pay" and a generic "Nálunk mindig biztonságban vagy, mert a Billingo mindig naprakész és megfelel a legfrissebb magyar jogszabályoknak" ("With us you are always safe, because Billingo is always up to date and compliant with the latest Hungarian law") compliance line but does not surface ePénztárgép / e-nyugta as a product; Kulcs-Soft (now ks.hu) lists a "NAV Online Számla" (NAV online invoicing) feature inside Kulcs-Könyvelés but no ePénztárgép module on the homepage; Cashy.hu (cashy.hu and www.cashy.hu) returned ECONNREFUSED at the date of writing and could not be verified; Laurel Kft.'s homepage names "Készletgazdálkodási rendszer, önkiszolgáló kassza" (inventory-management system, self-service checkout) but does not name ePénztárgép / e-nyugta / NAV-pénztárgép specifically; Számlaközpont's homepage markets "E-számla mindenkinek" (e-invoicing for everyone) and archiving but no ePénztárgép. They were therefore dropped per the named-niche-on-homepage rule. NAV's own ePénztárgép cloud app is the regulator's own platform and is referenced in section 01 as the regulator-published reference implementation, not as a third-party solution provider.
