Conveyance/Transport Allowance is provided by the employer to an employee as part of your salary for meeting employee transportation costs from residence to workplace.
It is exempt up to Rs.19,200 per annum (Rs.1600/month) under section 10 of the Income Tax Act.
This cannot be claimed unless it has been explicitly given to you by the employer as part of your salary. You can find the details in your Form 16 or salary slip.
