While the government appointed investigator Amy Rader Olsson said taximeters should be mandatory for all cabs, she did open up the possibility of a new category of taxi that can use another way of measuring payment using technology or other systems available.
Several new companies have in recent years established themselves in large cities and offered taxi-like services at low prices.
This includes the now-defunct service Uber Pop, where individuals drove customers for payment. According to Uber Pop it was carpooling.
The investigation proposed regulating car-sharing and said that drivers should establish themselves as a taxi company.
"The profit cannot be for the driver, it must be for the company," Amy Rader Olsson says to Radio Sweden.
Uber Sweden's managing director Martin Hedevåg is not pleased with the conclusions of the evaluation.
He tells Swedish Radio: "We are disappointed that it is not more progressive. It will be difficult to connect people together on a large scale."
