Employees on a short-term overseas assignment may, under certain conditions, remain covered by the social security system of the country of their origin. Employees may remain covered by the Finnish social security system for a maximum of two years.
A posted employee is a person who is
posted by a Finnish employer;
covered by the Finnish social security system at the time of leaving;
working abroad temporarily.
All statutory social security insurance payments in respect of employees covered by the Finnish social security system are made to Finland. The basis for insurance contributions and certain benefits is usually the salary for insurance purposes.
Employees being posted require a certificate to prove that they are covered by the Finnish social security system. For employees going to work in EU countries, this is an A1. The certificate enables both employees and employers to avoid double payment of insurance premiums.
Employers can apply for a certificate of posting from the Finnish Centre for Pensions online or by filling out an online form which can be printed out.
