Since you have only 10 employees, your establishment is not legally required to go for PF registration unless, of course, your establishment wishes to do so. But always remember that once you are registered, you would need to continue to pay the PF contributions even if your strength remains the same or falls below 10.
As rightly said by some of the members, your establishment would also need to pay an equal amount of the PF contribution every month (including admin charges along with contribution to EDLI) to the respective PF Office. Now, this would be an additional financial burden for your establishment unless you have considered that while calculating the CTC of each of the 10 employees. Moreover, your employees would now have a lesser take-home salary since a portion would now go towards the PF.
Check with the employees and your employer. If they both agree, you can go ahead and get the PF registration. Withdrawal from salary and remittance to the PF should be done only after you are allotted the PF code. Ideally, the PF scheme is actually beneficial to all employees and it provides financial help in the long run. Hence, it is advisable to go for it.
