You have to take YEL if:
• The average value of your estimated work input is about 649€/month, meaning a minimum of EUR 7 799,37 (2019) over a 12-month period.
• Your self-employment activities last for minimum of 4 consecutive months.
• You are 18–67 years old.
• You are not covered by any other pension law when you are an entrepreneur.
You must take out YEL insurance within 6 months to avoid penalty charge.
Taking the YEL insurance is easy through the websites of pension insurance companies. Add a purchase invoice of the YEL costs to the bookkeeping.
