Annual Social Insurance Report (Santei Kiso Todoke)

The annual social insurance report is submitted to the Japan pension service every July.

The employee’s monthly standard remuneration is re-determined every September to match the actual compensation the employee received. The employer submits the social insurance report in which the monthly compensation between April and June is stated.

As such, the new monthly standard remuneration, determined by the average compensation between the month of April and June, is then applied from the month of September (from October payroll).

Generally, this new monthly standard remuneration will be fixed until the August of the following year.
