The income confirmed for your YEL insurance is used as the basis for determining the amount of the maternity, special maternity, paternity, parental and partial parental allowance. The benefit is generally calculated in accordance with the level of the most recently confirmed taxation, which means that any parental allowance starting in 2019 is based on the YEL income for 2017.

If you are not working during your family leave, your YEL insurance can be terminated as ending on your last day of work. In this case, you will need to take a new insurance policy when you return to work. If you are working during your family leave, your YEL insurance is not terminated. It may, however, be necessary to adjust your YEL income if your work input in the company is reduced during the family leave.
