When you switch companies, you get a new PF account anyway. Some months back there was a talk of SSN which would be one account across employments, but I haven't heard anything more about the actual implementation.
My company pays me salary of 18000 rupees per month without tax and PF
But I have a salary account opened by the company
I am confused with these two statements. What do you mean without tax.
12 months @18K comes out to 2,16,000 which is definitely in the taxable bracket.
You mean they pay you in cash, across the table with no paperwork?
