Working with Monthly CPF Calculations

All of the CPF contribution rates are specified as monthly amounts and must be reported and paid to the CPF Board monthly, regardless of the pay frequency. To accommodate this, all of the calculations are based on month-to-date (MTD) amounts. In each case, they are calculated using the employees MTD wages and at the end, any existing MTD contributions already calculated are subtracted. Our rules are designed to have the deductions calculated in every pay. Wages are attributed only to a single month (determined by the period end date) and are not pro rated. For example, if you want to have some deductions calculated in the last pay of the month, you will need to create your own generation control elements to do that.
