Cook County Board President Toni Preckwinkle on Thursday will propose a penny-an-ounce tax on sweetened beverages including pop, lemonade and sports drinks to help close a 2017 budget shortfall, a move that comes just 15 months after she pushed through a penny-on-the-dollar sales tax increase, commissioners said.

The beverage tax would boost the cost of pop and the like by 72 cents for a six pack of soda or 68 cents for a two-liter bottle. The tax also would be imposed on fountain drinks. And it would be applied to drinks with sugar and artificial sweeteners, commissioners said. In its first year, it would raise an estimated $74.6 million.
