Dear Smita,
To determine what is taxable and what is not, you should refer to the Income Tax Ready Reckoner. However, it may not be easy to understand on your own. It would be better to discuss this with your Accounts/Finance person. Currently, there are very few benefits that are not taxable; almost everything is taxable. Basic Pay, DA, and Incentives are definitely taxable. PF (whether employee or employer's share) is not taxable. The same applies to Superannuation benefits. Additionally, there are some perks or benefits that do not attract Income Tax but may attract Fringe Benefit tax, which could be even higher than Income Tax. Therefore, it is advisable to consult your Finance person for further clarification.
