The company had sold 80,163 units in the same month last year.
In the passenger vehicles category, the global sales last month were at 49,821 units as against 50,042 units in January 2014, Tata Motors said in a statement.
Sales of luxury brand Jaguar Land Rover declined by 5.44 per cent to 36,527 units in January as compared to 38,631 units in the same month last year.
"The reduction is more than explained by the sales run out of the Land Rover Freelander model while retails of the new Land Rover Discovery Sport will start this month in some markets," the company said.
