Who has to set up a reporting channel
Under Section 12 HinSchG, every employer with usually at least 50 employees needs an internal reporting office. In the financial sector the duty applies regardless of headcount. Entities obliged under the Anti-Money Laundering Act (GwG) need a confidential reporting procedure under Section 6(5) GwG, and companies with at least 1,000 employees in Germany need a complaints procedure open to external persons under Section 8 of the Supply Chain Act (LkSG). The legal bases at a glance:
Whistleblower Protection Act: from 50 employees, always in the financial sector
From usually 50 employees an internal reporting office is mandatory (Section 12(1) and (2) HinSchG).
Regardless of headcount the duty applies to investment services firms, data reporting services providers, stock exchange operators, credit and financial services institutions, investment firms, counterparties under the SFTR, asset management companies, insurance undertakings, crypto-asset institutions, and payment and e-money institutions (Section 12(3) HinSchG).
Internal channels must allow reports orally or in text form, orally by telephone or another form of voice transmission (Section 16(3) HinSchG). The channel may also be opened to people in professional contact with the company, such as suppliers and service providers (Section 16(1) HinSchG).
Anti-Money Laundering Act: a reporting procedure for every obliged entity
Anyone obliged under Section 2 GwG must make arrangements under Section 6(5) GwG so that employees can report breaches of anti-money-laundering rules with their identity kept confidential. There is no headcount threshold; the arrangements scale with the type and size of the business. For estate agents and dealers in goods, risk management applies only to certain transactions (Section 4(4) and (5) GwG).
Supply Chain Act: complaints procedure from 1,000 employees
Companies with usually at least 1,000 employees in Germany need a complaints procedure for human rights and environmental risks under Section 8 LkSG. It is open not only to the company's own staff but to anyone, including workers at suppliers, and must keep their identity confidential. The government bill amending the LkSG (Bundestag printed paper 21/2474) drops the reporting duty but leaves the complaints procedure unchanged; a missing procedure remains subject to fines.
Supervisory law: an additional reporting process for financial firms
On top of the HinSchG, supervisory laws require a process through which employees can report breaches with their identity kept confidential: credit institutions under Section 25a(1) KWG, investment firms under Section 13 WpIG, insurers under Section 23(6) VAG, asset management companies under Section 28(1) KAGB and stock exchange operators under Section 5(8) BörsG.
AI Act: widens what can be reported
Article 87 of the AI Act (Regulation (EU) 2024/1689) applies the EU Whistleblower Directive to reports of infringements of the regulation. Since 29 July 2026 the HinSchG explicitly lists AI Act infringements in its material scope (Section 2(1) no. 10 HinSchG). This creates no separate duty to set up a channel: whoever already has to run a reporting office now also receives reports about the use of AI through it.
EU Corporate Sustainability Due Diligence Directive (CSDDD): from 2029 for very large companies
After the Omnibus amendment (Directive (EU) 2026/470), the CSDDD applies from 26 July 2029 to companies with more than 5,000 employees and more than EUR 1.5 billion worldwide net turnover. It then requires a notification mechanism through which reports can be made anonymously or confidentially (Art. 14(5)). Germany has not yet transposed the directive; until then the LkSG applies.
