LAS VEGAS — If the cash you doled out for a Las Vegas cab ride hurt your wallet, it’s not all in your head — auditors in Nevada also think taxi rates are outrageous.

Las Vegas-area cabs are overcharging customers to the tune of $47 million a year, according to an audit released Tuesday of the Nevada Taxicab Authority, which regulates the rides in Clark County.

Auditors for the governor’s finance office blamed a $3 credit card processing fee that they say is much higher than in other cities and probably shouldn’t exist. They also criticized a decision to increase a fuel surcharge even as gas prices are tanking, saying having the surcharge at all is unique among the 12 major Western cities that the taxi board tracks.

“The board’s decision is a windfall for the industry,” the audit says. “These are mostly tourist/visitor dollars that would otherwise likely be spent elsewhere in the local economy.”

The criticism comes a few months after ride-hailing companies Uber and Lyft started operating in Nevada with promises of cheaper and more convenient rides. The taxi industry, which makes big bucks taking tourists on a 5-mile trip from the airport to the Strip, fought hard against allowing the companies before losing its battle in the Legislature last spring.
