Social Security Contributions

The Social Security employee contribution deduction, SI EE CONTRI, and the employer contribution deduction, SI ER CONTRI, are calculated by multiplying the social security base amount, SI FM CAL BAS, with the corresponding contribution rates, SI VR EE RATE and SI VR ER RATE. The Social Security base amount comes from the SI BASE PTD period to date accumulator. Contribution rates are stored in a database record, and the array elements, SI AR INFOR and SI AR DT RATE, retrieve these rates from the database.

Global Payroll for Thailand enables you to process Social Security contributions in monthly, semi-monthly, or weekly payroll runs. The system calculates the Social Security contribution for weekly payroll runs using the calculation: MTD Social Security contribution amount + current week's Social Security contribution amount + projection of the Social Security contribution amount for the remaining weeks of the month.

Global Payroll for Thailand supports Social Security contribution amounts between 1,650 THB per month and 15,000 THB per month. If the actual contribution amount is more than the stated maximum contribution, then the system uses 15,000 THB as the Social Security contribution amount. If the actual contribution is less than 1,650 THB, the system uses 1,650 THB as the Social Security contribution amount.
