Labour Leasing Without an AÜG Licence in Germany
Providing employees to another company (labour leasing) without the required German AÜG licence can expose both the personnel provider and the client company to significant legal risks.
The licensing requirement generally applies when employees are supplied to another company, integrated into its organisation and subject to its work-related instructions. The rules can affect staffing agencies, payrolling providers and other businesses — even where their contracts describe the arrangement differently.
If your company may be engaging in labour leasing without the necessary authorisation, early legal advice can help clarify your position and identify the appropriate next steps.
When Is Labour Leasing Without a Licence Unlawful?
Under Section 1 of the German Temporary Employment Act (Arbeitnehmerüberlassungsgesetz – AÜG), labour leasing generally requires authorisation from the Federal Employment Agency (Bundesagentur für Arbeit).
The decisive factor is how the personnel arrangement operates in practice — not simply the contract’s title. Payrolling, outsourcing or a service contract may fall within the AÜG if the statutory criteria for staff leasing are met.
A licence must generally be in place before the assignment begins. Applying after an assignment has started does not retrospectively authorise the preceding period.
Some statutory exceptions exist, but they apply only where their specific requirements are fulfilled.

Fines, Legal Exposure and Licence Risks: What’s at Stake?
The consequences depend on the circumstances and the provisions that have been breached. Potential risks include:
- Administrative fines: Violations of the AÜG can result in fines. For certain offences involving unauthorised labour leasing, the statutory maximum is €30,000.
- Employment law consequences: The AÜG provides for circumstances in which employment or leasing agreements may be legally ineffective, potentially affecting the employment relationship between the worker and the client company.
- Regulatory scrutiny: The Federal Employment Agency may examine the arrangement and whether the business complies with the applicable licensing requirements.
- Consequences for an existing licence: Depending on the facts, violations may affect the status of an existing authorisation.
The applicable consequences must be assessed individually. A fine is not automatic in every case, and the legal position depends on the specific conduct, the parties involved and any relevant statutory provisions.

Already Started an Assignment? Know Your Options.
A company should not assume that submitting an application after the start of an assignment will remedy an earlier period of unlicensed staff leasing.
Where a licence is required, the business should clarify the legal position promptly and determine how to proceed lawfully. The appropriate steps depend on whether assignments have already begun, whether an application is pending and whether the company holds any existing authorisation.
If your company has already received questions or notices from the Federal Employment Agency, the correspondence and underlying personnel arrangements should be reviewed without delay.
See our guide to the AÜG Licence Application Process and our advice on AÜG Licence Denial or Revocation.
Address AÜG Risks Before They Escalate
If you suspect that your company has supplied or engaged personnel without the required licence, do not rely on the contract wording alone. A prompt review can help clarify the potential exposure and determine which steps are appropriate.

Consequences of Labour Leasing Without an AÜG Licence — Example
The German Law on Temporary Employment (AÜG, Arbeitnehmerüberlassungsgesetz) provides for fines to be imposed in a host of cases.
These are laid down in sec. 16 AÜG.
One case, for instance, is the assignment of employees without a license. This is called illegal temporary employment without a license.
A person who assigns a temporary employee or allows a temporary employee to work at customers on a payrolling or staffing basis needs a license to operate a temporary employment agency. A person who carries out these activities without a license commits illegal assignment of temporary employees.
This can be punished by fines of up to €30,000.
The law does not permit a temporary employment agency to be operated and the license to be applied for retroactively. This also constitutes illegal operation of a temporary employment agency and is punished by fines of up to €30,000 and revocation of the license granted.
