HR and Payroll Services for Expats and Foreign Employees in Poland

HR and Payroll Services for Expatriates and Foreign Employees in Poland

Hiring an employee from abroad or assigning an expat to a Polish company involves challenges that a standard HR and payroll system cannot address. Different tax rules, social security issues, double taxation treaties, tax residency certificates, and A1 forms— these are areas where mistakes are costly, and ignorance of the regulations does not exempt one from liability.

Aider Polska, as an HR service provider, supports Polish companies that employ foreign workers as well as subsidiaries of international groups to which employees are seconded from headquarters or other countries within the group.

We provide HR and payroll services in Polish and English.

The most common situations we handle in terms of human resources

- An employee hired by a foreign company and seconded to work at a Polish subsidiary of the group. It is necessary to determine whether the employee is subject to Polish social security, how taxation works in Poland, and whether the Polish company is required to withhold PIT as a tax withholder.
- An employee hired directly by a Polish company who is a citizen of another country. Depending on the employee’s citizenship, place of residence, and tax residence, the rules governing taxation and social insurance may differ significantly from the standard rules.
- Some foreign employees receive a compensation package that includes benefits such as housing, a car, schooling for their children, and a relocation allowance. Correctly classifying these benefits for tax and Social Insurance (ZUS) purposes requires knowledge and experience.

Working with a Tax Advisor
