A new tax went into effect Monday morning that takes aim at congestion in Chicago. It will affect you if you rely on Uber or Lyft to get around town. Riders heading into downtown Chicago will be charged an additional $1.75 tax per trip. That tax drops to $0.60 for shared-passenger trips. Some people feel like they are being hit by too many fees in the New Year, while others feel it will lead to less traffic and pollution in the city.
