On Tax Day, Burger King is offering Royal Perks members a one-cent cheeseburger with a purchase of $1 or more. This deal is available on the BK app and website for order-ahead at participating U.S. locations, excluding breakfast hours, delivery, and certain states. Other food brands like Potbelly, Paris Baguette, and Krispy Kreme are also offering discounts and freebies to help customers refuel after filing their taxes. Krispy Kreme customers can get a second dozen doughnuts for the price of their state’s sales tax when they order a dozen on Tax Day.
