Performs calculations and determinations related to ad hoc adjustments to social insurance.
Using the pay period in which a change in fixed wages occurred as the reference month (Month 0), enter the following for the three-month period from the reference month through Month +2:
combined with the past 9 months (–9 months to –1 month) from the reference month to form a one-year period,
and by entering variable wages and fixed wages (for the three-month period from the reference month to +2 months only),
the system calculates whether adjustments can be made on an ad hoc basis using either the standard three-month average or the exception one-year average.
By entering data for only the trigger month and the following two months, you can also perform a standard ad hoc adjustment determination.

Employee’s share of Employees’ Pension Insurance premiums ÷ 91.5 = Standard Monthly Wage (thousand yen)
Total Gross Pay = Fixed Wages + Variable Wages
The standard monthly wage for Health Insurance is the same as that for Employees’ Pension Insurance; however, amounts exceeding the Employees’ Pension Insurance ceiling or falling below its floor
will be calculated using Health Insurance’s own monthly rates, so please refer to the Health Insurance premium schedule.
The application of the annual average is limited. Please inquire with your pension office or health insurance association.
