Dear srija ramayanam,
If any company registered with PF organization it must deduct 12% Employee share on employee basic salary there is no minimum and maximum limit for PF deduction ( on basic).there is two method to calculate PF on employee salary,
1.Taking basic salary as 6500/- for all employees whose basic is more than 6500/- ,If employee basic is less than 6500 in this case take the actual basic.
Example : If the basic of an employee basic is 4500 then calculation of PF is 4500*12% ( basic is less than 6500/-)
If the basic of an employee basic is 10,500 then calculation of PF is 6500*12% ( basic is more than 6500/-)
2. Take actual basic and calculate 12% on that (what ever the basic less than or more than 6500 take actual base just like the above said 1st example)
Apart from PF there is one more option for employees that is Volentory PF means in addition to regular PF deduction the as per employee wish the employee deduct VPF, for this minimum % is 12% and maximum is 80% on basic. Mostly employee opt this for getting Tax relief but it is very beneficial to employee
