Hi,
ESI is applicable only for those employees whose gross salary is up to 10,000/- rupees per month, and it's calculated at 1.75% of gross salary from the employee's side and 4.75% of the same from the employer's side.
PF is calculated on basic salary + Dearness allowance only. It is calculated at 12% of basic salary from both sides. Out of the employer's 12% contribution, only 3.67% goes to PF, and the rest goes to the Pension Fund. The maximum ceiling to be covered under this Act is 6,500/- basic salary. Even employees earning more can also be included.
Professional Tax is calculated on gross per month, and it's fixed for a level. For employees who are earning up to 6,000/-, the deduction would be 20/- rupees, but it varies from state to state.
Regards, Amit Seth.
