The case contends, however, that although Uber and its subsidiaries were prohibited from deducting any amounts from drivers' pay other than service fees, the company made further deductions represented as "sales tax" and surcharges for the Black Car Fund, a non-profit that provides workers' compensation for black car drivers. Further, the case states that these allegedly improper deductions, made only for trips within New York State, came in addition to Uber's typical 20-28 percent fee of a ride's total fare. The lawsuit goes on to claim that Uber continued to make improper "sales tax" and Black Car Fund deductions from drivers' pay until the allegations from another class action led the company to revise its contract terms to allow for both deductions. Uber, in May 2017, amended its terms so that drivers were no longer promised the full fare paid by the passenger with only a service fee deducted and switched to a rate structure the company claimed was simpler and more transparent, the suit explains.
