Germany EOR 18-Month Limit: What Employers Must Do Before Month 18
You hired an employee in Germany through an Employer of Record. The employee is fully embedded in a client project, performance is strong, and collaboration runs smoothly. Everything seems to be on track, until someone checks the timeline and realises the assignment is approaching month 16.
At that point, the 18-month rule under the German Arbeitnehmerüberlassungsgesetz (AÜG) suddenly becomes highly relevant. Under this legislation, the deployment of a leased employee to the same end client is generally limited to 18 consecutive months.
In this blog, we explain what the German 18-month rule under the AÜG means in practice for employers using an EOR structure and why it often becomes urgent around month 16. We outline your main options, why planning should start as early as month 12, and how solutions like NRP conversion can support business continuity. We also highlight the risks of poor coordination and unexpected budget impact. Finally, we show how we, as Parakar, help employers stay ahead of the 18-month deadline, before it disrupts operations.
What the 18-Month Rule Means in Practice
For companies operating in Germany through an Employer of Record (EOR) model, the 18-month rule can come as an unwelcome surprise. In many cases, the employee is already deeply integrated into the client’s organisation, involved in long-term projects and critical to ongoing operations. When the 18-month limit approaches without a plan in place, operational pressure increases quickly. Projects risk disruption, client relationships may be affected, and legal exposure rises if the situation is not handled correctly.
The 18-month rule is not a minor administrative detail, it is a strict regulatory requirement under the German Labour Leasing Act. Temporary worker deployment to the same end client is limited to 18 consecutive months. This applies to EOR and labour leasing structures but does not apply to direct employment through your own German entity.
The concept of “same client” is assessed in practice. Authorities look at the actual legal entity and the real working situation, not just what is written in the contract. If month 18 is exceeded without restructuring, the employee cannot continue in the same deployment under the same structure. This is not a theoretical risk; it is a hard legal stop.
For that reason, companies using an EOR structure in Germany should treat the 18-month mark as a workforce planning milestone, not as a last-minute compliance issue. The key is early planning.
The Typical Scenario
A common scenario is straightforward: a company hires an embedded engineer through an EOR. Around month 16, someone realises that the 18-month limit is approaching. The project is still ongoing, and the employee remains critical to delivery.
Without a compliant transition, the assignment must end at month 18. When the issue is discovered late, decisions become rushed and options narrow quickly. When identified early, companies retain flexibility and control.
Your Main Options
When approaching month 18, companies generally consider five routes.
- Switching the assignment to another German legal entity within the same client group can work if such an entity exists and the role genuinely sits there.
- Benching the employee for three months plus one day technically breaks continuity, but salary and employer costs continue during that time. This is often expensive and operationally difficult.
- Termination and rehire carries litigation and severance risk and can damage employee trust. It should only be assessed with legal guidance.
- Converting the employee to direct employment with the client is usually the most stable long-term solution. This requires payroll setup and proper transition planning.
- Setting up a Non-Resident Payroll Registration in Germany. Through an NRP, a foreign employer can run German payroll without establishing a full German entity. The employee can then convert from EOR to direct employment under the foreign company’s NRP registration. This is often an efficient interim or long-term solution when a local entity is not yet established.
Each option has different timelines and cost implications. The right solution depends on preparation.
The Smart Timeline: Start at Month 12
Companies that manage the 18-month rule effectively do not wait until month 17. At month 12, HR should already trigger a compliance review. This creates sufficient time to assess whether:
- The assignment can move to another legal entity
- The client should convert to direct employment
- An NRP setup the most efficient route is
- A German entity needs to be established
Setting up an NRP or preparing direct payroll registration typically takes several weeks. A structured conversion from EOR to direct payroll often requires six to ten weeks if handled properly. If the process only begins at month 16, the margin for error becomes very small.
Why NRP Conversion Is Often the Best Bridge
For many international companies, establishing a full German entity is not immediately feasible. An NRP setup allows the foreign employer to become the direct employer in Germany without incorporating locally.
This enables:
- Continuity of employment
- Compliance with German payroll obligations
- Avoidance of the 18-month limitation
- A structured transition from EOR to direct employment
When prepared in parallel with the EOR timeline, conversion via NRP can be smooth and cost-effective.
The Real Risk Is Poor Coordination
Handling the 18-month limit requires coordination between:
- Legal, to assess entity switching and employment risk
- Payroll and finance, to manage cutover timing and cost modelling
- Immigration, if the employee requires sponsorship
- HR, to prepare new contracts and preserve seniority
- Project teams, to manage client expectations
When teams act early and in alignment, the transition is often almost invisible. When action is taken too late, projects can stall and costs increase.
Budget Reality
In most cases, structured conversion costs are modest compared to the financial and operational impact of disruption. Benching an employee means continuing full salary and employer contributions during the bench period. Poorly managed termination can result in severance exposure, often calculated based on monthly salary multiplied by years of service.
Emergency decisions almost always prove more expensive than proactive planning.
