You must notify Kela if you are covered under the Finnish social security system and start a job or switch employers while abroad. If you leave Finland to work in another EU or EEA country, your social security coverage will usually be transferred to your country of employment regardless of how long your employment there will last. Read more about the social security coverage of persons working outside Finland.
If you are a so-called posted worker and will work in another EU/EEA country or in Switzerland, your employer must apply to the Finnish Centre for Pensions for an A1 certificate before the posting is set to begin. With the certificate, you can prove that you are covered by the Finnish social security system during your posting. You should also contact the Finnish Centre for Pensions if you have any other specific questions or concerns about working in another EU or EEA country.
Posted workers, posted self-employed persons and civil servants, along with their family members, can retain their social security coverage in Finland during a period of employment lasting more than six months in a country other than an EU or EEA country. The employment outside Finland must be notified to Kela.
The social security coverage of employees and self-employed persons who move to a country that has a social security agreement with Finland is normally determined by reference to the length of their residence abroad. The exception to this are employees and self-employed persons who move to another Nordic country. Their coverage is largely determined according to the same rules that apply to employees moving to another EU or EEA country.
