EPF (provident fund)
The Employees' Provident Fund: a retirement savings scheme employer and employee both pay into each month.
Once a business is covered by EPF, it deducts the employee's share from their pay, adds its own share, and deposits both each month with a return. The money builds into the employee's retirement savings.
When it applies depends on how many people you employ. The deposits have fixed monthly dates, which the filing calendar shows for a business that has staff.
