Two practical updates for Hungarian businesses this week (2–8 November 2026): a clear timeline for mandatory eÁFA, and a simpler way to file cash-register changes with NAV.
What changes
- eÁFA — largest taxpayers: from 1 July 2027 if you were among the largest taxpayers in 2026, file monthly VAT returns and are established in Hungary. NAV notifies you electronically by 15 December 2026; your first eÁFA return covers July 2027.
- eÁFA — almost everyone else: from periods that include 1 January 2028, eÁFA becomes mandatory for nearly all other VAT filers. Paper filing stays only for a narrow special group (Andersen, 5 Nov 2026).
- Two filing routes: approve NAV’s draft return in the web interface, or send transaction-level data from your own systems via machine-to-machine (M2M). High invoice volumes usually need M2M — and a ready ERP.
- NAV Cash Register Portal (3 Nov 2026): if you run online cash registers or taximeters, you can file the PTGTAXUZ form in the browser, without ÁNYK. Covers suspend/resume, withdrawal, loss/theft/destruction, and changes to operating location or receipt header (e.g. shop name). Report location or mode changes by the 5th day before the change (NAV, 3 Nov 2026).
What to do
- Check whether you’re likely among the 2026 largest taxpayers; if yes, watch for NAV’s notice by 15 December 2026.
- Compare NAV’s eÁFA draft with your Odoo VAT report; clean partner tax IDs and invoice data that flow to NAV Online Számla.
- If you run online cash registers, try PTGTAXUZ on the portal before your next location or header change.
- Plan M2M readiness early if invoice volume is high — don’t wait until mid-2027.
Opportunity
Starting now means fewer surprises when eÁFA becomes mandatory. Odoo with Hungarian localization (InnOpen) keeps VAT reports, partner tax data and NAV Online Számla flows in one place, so you can test and fix gaps before the deadline — not under it.
