Customers are feeling the pinch of Seattle’s new Sweetened Beverage Tax. At Costco, a $15.99 case of Gatorade now costs an additional $10.34 due to the tax. The new tax went into affect on January 1, 2018 and tacks on 1.75 cents per ounce. It affects soda, sports drinks, kombucha, and other sugary beverages that don’t list milk as their first ingredient. “If you buy in bulk, you’re going to notice it. If you’re just buying an individual can, you probably won’t blink,” KIRO Radio’s Tom Tangney said. Many Seattle residents are upset about the tax. Some don’t want to pay more for soda and other drinks. Others think the tax is regressive, meaning it disproportionately affects low-income families. And still others question why the tax leaves out sugar-heavy beverages like many of those sold at Starbucks.
