VerificationSource and limits
- Source: NAV VAT-subject register, retrieved 18 August 2026.
- The headcount is NAV's current figure, not the annual average reported in a filing. The two normally differ.
- Absence from the public-debt-free register does not mean a company owes tax: it may simply never have applied.
- Felhő is not affiliated with NAV and is not an authority.
