Global expansion no longer ends with just opening an office in a new market. Talent shortages, regulatory complexities, and multi-country operations are knocking on your door simultaneously. Teams looking to onboard foreign personnel in the EU through temporary employment models must manage work/residence permits, posted worker notifications, local payroll, social security, and equal pay rules in a single flow. A misstep can mean project delays, fines, and reputational risks. In this guide, you will find up-to-date practices as of October 2025, key considerations, and actionable recommendations filtered from Corpenza’s field experience.
1) The framework of temporary employment in the EU: Which model for which scenario?
Basic models of temporary employment
“Temporary employment” in the EU does not refer to a single format. Different objectives require different legal pathways. The right model determines the budget, time, and compliance risk.
- Staff leasing: A licensed agency keeps the employee on its payroll; you are responsible for the assignment location and outcomes.
- Posted worker: You temporarily assign from one EU country to another; comply with the minimum wage and working conditions in the host country, clarifying the scope with an A1 social security certificate.
- Project-based short contract: Focus on a specific deliverable; clarify contract and intellectual property provisions according to national law.
- Local employment/single permit: Directly employ in the target country and obtain a work + residence permit.
Which path should you choose in which situation?
Establish a balance of speed, flexibility, and continuity according to your operational goal.
- 6–12 month projects with clear deliverables: Prioritize the posted worker or staff leasing model.
- Small teams testing product/market fit: Proceed with temporary employment + local payroll support for low fixed costs.
- Continuous revenue and long-term customer commitments: Plan local employment and residence/work permit processes.
- Highly skilled profiles and scarce talent: Check accelerated pathways like the EU Blue Card.
2) Permits, posted worker rules, and documents: From basics to advanced
Work/residence permits for non-EU citizens
Choose the correct permit when temporarily employing third-country nationals in the EU. Names and thresholds vary by country; the logic remains the same: qualifications, salary, job description, and employer eligibility.
- EU Blue Card: An attractive framework for highly skilled positions; implemented with more flexible thresholds in many countries.
- Single Permit: Work + residence in a single application; the most practical route in many countries.
- Seasonal permits: For periodic needs such as agriculture, tourism, and hospitality.
- Intra-company transfer (ICT): Use for sending managers/specialists/trainees within the group.
Your permit file should include a clear job offer, proof of your diploma/experience, a contract showing your salary level, and health insurance. Always keep country legislation up to date; align process timelines with the project schedule.
Posted worker: Notification, equal treatment, and A1 certificate
If you are temporarily sending your employee from one EU country to another, apply the rules under the Posted Workers Directive.
- Make a prior notification: Notify the assignment according to the portal in the host country.
- Provide equal pay and conditions: Minimum wage, overtime, annual leave, and occupational health and safety are processed according to the host country.
- Obtain an A1 certificate: Prove where social security contributions are paid with the A1.
- Appoint a representative: Many countries require a local contact person; this speeds up checks.
Mandatory records and audit file
Show a complete file when an audit comes. Keeping documents up to date, accessible, and in two languages shortens the audit.
- Identity and work/residence permit
- Employment contract and assignment letter
- Payroll payments, salary items, leaves
- A1, health insurance records, working hours
- Host country notifications and correspondence
3) Payroll, tax, and equal treatment: The backbone of compliance
Set up payroll and social security flow correctly
Incorrectly set up payroll can disrupt even the best project. The employee’s legal tie, social security coverage, and salary items must be clear.
- Set up local payroll or use a licensed provider.
- Clarify the social security country with A1; otherwise, register in the host country.
- Apply host country rules for fringe benefits (travel, meals, accommodation).
Tax and invoicing: Simplify cash flow
Cross-border tax is shaped by contract structuring. Clarify the invoicing structure before starting the project.
- Use payroll services for distributed teams; expense salaries of remote and contracted workers under a single invoice.
- Identify operations that may create PE (permanent establishment) risk; manage with company formation or representative office solutions.
- Establish international accounting structure; schedule VAT, withholding, and summary obligations.
Equal treatment and occupational health and safety: Key areas checked in audits
Complying with the basic working conditions in the host country is the red line for posted workers and temporary employment.
- Equal pay: Provide local equivalent salaries and fringe benefits.
- Working hours and leave: Comply with national limits, shift, and holiday rules.
- Occupational health and safety: Document risk assessments, training, and equipment provision.
4) Updates and market opportunities in the 2025 calendar
Trends at the EU level
Europe is streamlining channels to close the talent gap; audits are tightening. Digital application portals and e-document verifications are speeding up processes.
- The updated framework of the EU Blue Card operates with more flexible thresholds in many countries; you will see more flexible transitions in job changes.
- Online notification and appointment systems will become widespread; keep the file digitally ready.
- Labor inspectors will focus more on equal pay and accommodation standards.
Country-specific highlighted changes
- Finland: Grants a new 3-month job search period for third-country workers whose jobs end early; applies an income threshold of €1,600/month for work-based residence.
- Poland: Will streamline work permit processes by mid-2025 and eliminate the labor market test; will strengthen digital application and audit infrastructure.
- France: Discussions on prioritization for employment will continue in 2025; the list of in-demand professions will open doors to faster permits.
- Germany: Qualified migration reforms and the Chancenkarte approach provide flexibility in point-based entry and recognition processes.
Each country’s implementation varies. Check official resources before applying; structure the project timeline according to this reality.
Red flags and audit readiness
- Unregistered assignments: Do not send personnel to the field without notification.
- Incorrect salary scale: Verify the host country’s collective agreement and minimum wage data.
- Social security without A1: Do not employ without clarifying the contribution country.
- Insufficient accommodation standards: Document housing conditions in construction and field jobs.
