OAKLAND — Oakland is moving ahead with plans to tax Uber and Lyft drivers, but it first needs to figure out how it will do so.

At a city finance meeting Tuesday, council members expressed concerns about unfairly charging a flat rate to drivers who drive part time and rarely visit Oakland.

San Francisco recently obtained the names of some 30,000 drivers and sent notices reminding they need business licenses to drive there.

Oakland is considering an annual flat tax of $72, similar to what taxicab drivers already pay.

City leaders on Tuesday said they plan on issuing subpoenas for the names of drivers if they are not provided by the companies. From there, they will contact individual drivers to get fare records to see who drives in Oakland, officials said.

“While this might be better than doing nothing, it would be very costly and take a lot of time,” Council member Rebecca Kaplan said.

Kaplan, who along with Councilman Dan Kalb asked for Tuesday’s informational report, said it would be easier for the companies to send one check, instead of hundreds of drivers submitting their own.

The finance committee of the City Council voted to accept the report from Margaret O’Brien, the city’s revenue and tax administrator, and asked for a more detailed report on how to collect the taxes at a meeting in January.
