Before you decide, answer these questions:
1. Whether separate or combined, for the purpose of PF applicability and registration, should a combined strength of the number of employees be taken? For example, in the Head Office, it's 5, and in the Branch, it's 15.
2. Are your employees in the Head Office and Branch Office interchangeable, or is there no possibility? This is desirable as your payrolls are run separately, and for the purpose of remittance, you may encounter some practical difficulties.
3. How are your labor licenses and registration of establishments obtained? Are they separate or combined?
4. Also, consider the impact of ESIC.
5. Are the Head Office and Branch Office located in different places and separated in two different states?
6. If your strength is greater than 100, you can have an exemption and establish your own PF Trust with due permission from EPFO.
Now, considering your separate payroll arrangements, it is convenient to have separate registration and remittances, returns, etc. This will enable you to process your PF remittances, ledgers, transfers, advances/withdrawals, settlements, etc., very conveniently as they are within your control and all details are available internally. On the other hand, if you combine with the Head Office, you will have to communicate with them.
However, both arrangements are acceptable and permissible; the decision is yours.
