Starting a New HR Role: Can Anyone Explain the Current PF/ESI Rules and Processes?

I am going to join an organization in a day or two after completing my MBA. I had worked in HR for about 2-3 years before joining my MBA program. At that time, the PF account of the employee used to be opened through some forms. I have the following questions if any expert could answer them (as per Delhi state rules). I will be very thankful.

Current Process of Opening a PF Account

What is the current process of opening a PF account for a newly joined employee? (Is it online or offline?)

Best Possible Salary Breakup

What could be the best possible salary breakup to provide maximum tax benefits to the employee while complying with all the laws? (Consider a gross salary of 50k).

Monthly Return Filing Process

What is the process of filing returns monthly? Do we have to file, or do we just need to inform the inspector of EPFO? Is it online or offline? Is it mandatory?

Yearly Return Filing Process

What is the process of filing the yearly return? Is it all online or offline? What things do we include in the return? Is it mandatory?

Depositing PF/ESI Amount

How can we deposit the PF/ESI amount to the PF department? Is it monthly? Is it online or offline?

ESI Requirement for Factories

Is it true that ESI is required only for factories?

Salary Processing Details

When we process salary, what details and in what form do we give to the finance department? I actually want to know the method of salary processing.

Thanks in advance!

PF Account Opening Process for New Employees
A new employee, at the time of joining an organization, has to fill out Form-02 (Nomination Form). Then the employer will create a new ID for the new employee and update their personal information provided in the form on the PF portal. If an employee is already a PF member, they have to fill out Form-11 when taking up new employment. The employer will then register their PF number under the employer's establishment.

Tax Information
I don't know about tax (TAX).

Filing Returns
Both monthly and yearly returns will be submitted online.

PF and ESI Contributions
You have to pay PF and ESI monthly contributions through the online payment facility available on the respective website after generating a challan for the same.

ESI Applicability
ESI also applies to medical institutions, educational institutions, hotels, restaurants, newspaper establishments, etc.

Salary Processing
In the salary process, leave details, PF and ESI, or other deduction details must be included. I am sorry, but I don't have the form.
