Under Section 17(1) of the Income Tax Act — wages, pension, gratuity, fees or commission or profits in lieu of salary, advance salary, payment for leaves standing to the credit of the employee — have all been included under the definition of salary. This is taxable in the hands of the employee.
The Income Tax Act has laid down that 'scholarship granted to meet the cost of education' is exempt from income tax under Section 10(16).
So, whether it should be taxed or not it depends on the nature of stipend.
It is a scholarship when:
The stipend is paid for someone to support their education. Research fellowships, grants received from universities are all exempt. Note that it doesn't matter if the person exhausted the money fully or saved amount of it, as long as it has been paid for someone's pursuit of education.
It is a salary when:
MBA graduates or engineering graduates receive stipend during an internship at a company
The stipend letter may or may not include a break up like a salary letter does. This may or may not be similar to the employment letter offered to a full time employee. However, if this payment is made for you to gather an experience and perform services similar to an employee, such stipend income shall be taxable.
So depending upon the nature of stipend, at the same time the amount of stipend it need to be classfied. If a same is a nominal amount which is to support the working expenses then the same is considered as exempted.
