(KTRS) – A provision in a piece of legislation would keep drivers for ride-hailing companies from paying some taxes, including the St. Louis earning tax.

The bill was written to allow the St. Louis Metropolitan Taxicab Commission to create a statewide standard for services like Uber. The Post-Dispatch reports that a piece of the bill would exempt those drivers from local taxes. The news comes as St. Louis is fighting to keep the one-percent earning tax in place. Voters take to the polls in April to reapprove the tax.

Opponents of the bill say too much of the city’s revenue comes from the tax.
