Dear KKT,
Bonus is not taxable; as such, the component of bonus is very small and is not taxable. As per the law, the maximum limit for bonus is 3500 basic salary of the employee. Therefore, a person who is receiving a basic salary of Rs. 3500 and if the DA component is not included, his actual salary will not exceed the taxable limit.
However, the taxability of bonus depends on the company's policies. Yes, bonus is taxable as it is a part of the CTC salary, and in the annual return, you are required to declare it as income. Therefore, it is taxable.
