EFTA Court clarifies when a minor activity must be disregarded in social security coordination
On the 3rd of July, 2026, the EFTA Court clarified how a minor activity should be treated when authorities decide which country’s social security system applies to a person working across borders. In Case E-26/25 the Court held that an activity generating less than 0.5% of a person’s income creates a strong presumption that it is marginal and must be disregarded, a point that matters to any employer whose staff hold an A1 certificate across two or more European Economic Area (EEA) states.
