# Whistleblower law in Hungary

Hungary implemented Directive (EU) 2019/1937 through **Act XXV of 2023** on complaints, public interest disclosures and rules related to reporting abuses, in force since **24 July 2023**. The Hungarian framework places the official external channel with the **Commissioner for Fundamental Rights**.

## Applicable law

- [Act XXV of 2023 — official text](https://njt.hu/jogszabaly/2023-25-00-00)
- [Commissioner for Fundamental Rights — public interest disclosure / whistleblower report](https://www.ajbh.hu/en/web/ajbh-en/public-interest-disclosure-whistleblower-report)

## Who must establish an internal channel

Private employers with **at least 50 employees** must establish an internal reporting system. Public-sector bodies and certain specifically regulated entities also follow the act's whistleblowing rules.

## External reporting authority

The official external reporting system is operated by the [Commissioner for Fundamental Rights](https://www.ajbh.hu/web/ajbh-en/submitting-public-interest-disclosure-whistleblower-report), which accepts public interest disclosures and whistleblower reports through its dedicated system.

## Data protection authority

For GDPR complaints relating to the handling of report data, the relevant authority is the [Hungarian National Authority for Data Protection and Freedom of Information (NAIH)](https://www.naih.hu/).

## Key compliance points

- Hungary's official terminology still strongly links whistleblowing to the public-interest disclosure framework.
- The official external system accepts reports with or without identification, but the handling consequences differ depending on whether the reporter identifies themselves.
- Organisations entering Hungary should be careful to separate statutory whistleblower handling from any broader ethics or grievance channel.
