The benefits of the basic security begin with the application. There are no additional payments for periods prior to the application. The basic security benefit is regularly approved for 12 calendar months and then reviewed. If the personal or financial circumstances change during the approval period, the changes must be notified. Increased benefits will be paid at the earliest from the first of the month in which the notification of change was made. Therefore, it is important to notify changes, such as a rent increase, immediately.
