Evidence of impact / measured public value3/3
EC VAT Gap Reports document Hungary's VAT compliance gap falling from 21.67% (2013) to 2.31% (2022), the EU's best result, with each RTIR phase extension matched by a measurable step-down; independently corroborated by OECD Tax Administration 3.0 reports.
Transparency, fairness & accountability1/3

Transferability / demonstrated replication2/3

Governance, capability & sustainability2/3
NAV operates under Hungarian tax law and EU eInvoicing directives; taxpayers have formal appeal rights; the MIMCS AI working group was formalised in 2022, but ML model governance and algorithmic audit mechanisms are not publicly disclosed.
