Hungary: Tax authority announces stricter approach to online invoice reporting errors
Beginning September 15, 2025
The Hungarian Tax Authority (HTA) announced that beginning September 15, 2025, it will be taking a stricter approach toward certain types of errors related to online invoice reporting.
The key change is that several issues previously classified as warnings (WARN) will now be treated as blocking errors (ERROR). When such errors occur, the data will not reach the tax authority’s system, and the mandatory reporting for the given invoice will not occur. The change primarily affects invoices issued in foreign currencies on transactions within the EU or with third countries, as well as modification invoices.
