hi,
First, it is a statutory compliance to deduct PF if the employee of an organisation whose strength is 20 or more, is getting 6500/- or less per month(Basic + DA only). Noone can opt any decision contrary to that.
Secondly, If an employee is already covered under PF then it does not matter what his salary is this time.
The case will remain same if he comes from another companies where he was covered ,to a company where PF Applies whether he crosses the limit of 6500/- per month.
Last, If a new employee joins who was not covered before(may be a fresher or whoever) & his Basic + DA is more than 6500/- per month then it is the employer who may decide whether to include him in PF or not.
