Seconded staff service – comprehensive support for managing staff abroad

Seconding employees abroad is an opportunity for company growth and international projects. However, seconded staff service requires precise planning, knowledge of regulations and attention to formalities – both in Poland and in the country to which the employee is sent. 

EFEKTA Accounting Office offers comprehensive support in seconded staff service, helping you to stay compliant with regulations and manage your team effectively.

Challenges related to seconded staff service

Companies seconding employees abroad face a variety of challenges, such as:

  1. Different labour and tax laws
    Each country has its own regulations on salaries, working time, taxation or social insurance contributions.
  2. Taxation and double taxation avoidance rules
    Management of seconded payroll taxes requires settlement in Poland and abroad, in accordance with international agreements.
  3. Settlement of allowances and benefits
    Costs associated with the business trip, such as allowances, accommodation or travel, must be recorded and settled in accordance with the regulations.
  4. Documentation and permits
    Preparing the relevant documents, such as the A1 certificate, work permits or other permits required in a particular country, is essential for legal employment.
  5. Monitoring of working time and compliance with local regulations
    Countries such as Germany and France have strict minimum wage and working time regulations that must be taken into account.

FAQ – Frequently Asked Questions

What is the A1 certificate and why is it crucial?

The A1 certificate is a document confirming that an employee posted to work in another EU country remains subject to the Polish social security system (ZUS). This allows you to avoid paying contributions in the destination country. The EFEKTA firm handles the entire process of obtaining these certificates.

How can double taxation of employee salaries be avoided?

Double taxation is avoided based on international tax treaties. Our team ensures that remuneration is settled in accordance with the regulations applicable both in Poland and in the posting country, applying the appropriate tax settlement methods.

Do I need to adjust the employee’s salary to the rates applicable abroad?

Yes. Many countries (e.g., Germany or France) have strict minimum wage laws and specific working time regulations. As part of our services, we monitor local requirements to ensure your payroll is fully compliant with foreign regulations.

What allowances are employees entitled to abroad, and how should they be settled?

Posted workers are entitled to per diems, as well as reimbursement for accommodation and travel expenses, among others. EFEKTA precisely calculates these allowances, ensuring they are properly recorded and fully compliant with both Polish and foreign tax regulations.

What documents must I prepare before sending an employee abroad?

It is necessary to prepare the appropriate contracts (posting annexes), A1 applications, and in some cases, work permits or notifications to local registries (e.g., the SIPSI system in France). We comprehensively prepare and verify this entire set of documents for you.

Does EFEKTA contact foreign institutions on our behalf?

Yes. We provide representation before government authorities – both Polish (ZUS, Tax Office) and foreign inspection bodies. We take the burden of formalities and communication with supervisory authorities entirely off your shoulders.

What happens if the regulations change in the country where my team is posted?

We operate proactively. We continuously monitor changes in international labor laws and tax regulations. If the rules in a given country change, we immediately notify our clients and adjust the settlement processes accordingly.

Why should I choose a dedicated specialist from EFEKTA?

Posting workers is a process carrying significant legal and financial risks. Partnering with a dedicated advisor at our firm guarantees a tailored approach, operational efficiency, and security – we minimize the risk of penalties resulting from non-compliance in another country.
