What happens to my state pension while working overseas?
Pensions
In every EU/EEA country where you have made social security contributions, your record is preserved until retirement age. If you have made contributions for at least one year in any one country, that country will have to pay you a state pension when you reach retirement age. If you have contributed in any one country for a relatively short period, your entitlement to the state pension will be quite small.
In the case that you contributed in a country for less than one year, your contributions will not be lost. They will be taken over by the country where you have made most of your contributions during your working life, or by your final country of employment.
As long as you stay within the EU/EEA countries, any time spent contributing to the social security system of an EU/EEA member state will count towards your overall state pension.
