Hi,
Your query is not very clear; that's why there has been no response. For ESIC, the ceiling is 15k gross salary. Employees above 15k per month are not covered by the ESIC scheme.
The EPF scheme, as started, had a limit of 6500 basic salary, of which 12% is deducted. Many organizations either deduct the PF at 12% as per the spirit of the law, thus helping employees save money and receive a fixed interest of 8.5%.
Some organizations have adopted a policy of taking advantage of the maximum limit and deducting 12% of 6500, i.e., 780 per month, rather than 12% of the basic salary. Thus, the difference lies in either just fulfilling the law or applying the law in spirit.
