Income from Outside India

I was in USA for 3 months for company work in last year. The company which is in India paid me 50$ per day for my daily expenses in USA. In those 3 months i saved around 1.5 lacs rupees. After returning to India these 1.5 lacs which are in dollars i returned to my company officials. My company transferred this amount into my bank account, other than my salary. Is this taxable income...???
