From that moment, every person who works or has registered in the Netherlands must take out insurance.
This is a big expense, so that the budget of low earners is not affected by this obligation, an allowance has been established, which in 2020 is maximum € 104,= per month for single persons or € 199,= pairs (its amount depends on income).
The deadline for submitting applications for 2020 is 31-08-2021. Off course, the submitting application for 2021 is 01-09-2022.
