The Indian subsidiary of Coca-Cola Co (KO.N) said on Friday it may have to close some bottling plants if the government pushes through a proposal that would subject fizzy drinks to a 40 percent "sin" tax, as part of a broader fiscal overhaul.

"It will lead to a sharp decline in consumer purchase," Coca-Cola India said in a statement. "In these circumstances, we will have no option but to consider shutting down certain factories."
