So, if you had been employed and receive a pension from your employee, you need to treat that pension under salary. But, if you receive family pension, say for example a wife receives pension after her husband's death it has to be treated as "income from other sources" and not under "salary" because the wife was not working, while her husband was.
Hence, it's important to make a proper classification and ensure that the pension income is shown under the appropriate head.
Family members who receive pension shall be exempted from Income Tax, if the family member was a recipient of the Param Vir Chakra, Mahavir Chakra or any such gallantry award.
It's important to note, any ex-gratia lump sum payment received by the widow of an employee who dies in service will not be taxable under the Income Tax Act.

2) Non-Government Employees
