Payroll Calculation

1.Payroll Calculations

- In Japan, employers are the designated payer of taxes and social insurance premiums including the amount to be borne by staff.
- Employers pay salary to staff after withholding taxes and insurance premiums from salaries.
- Payroll calculations are needed for computing the accurate amount to be paid to staff after subtracting taxes and premiums that are imposed on staff.

Flow of Payroll Calculations
Monthly work (i) Calculation of the gross salary (for each employee).
(ii) Calculation of the amount to be subtracted.
(iii) Payment of salary after subtraction.
(iv) Payment of health insurance premium, withholding income tax, and residential tax.

  • Errors in payroll calculations lead to employees’ distrust of employers.
