Democratic state lawmakers on Thursday announced a $400 gas rebate proposal for every California taxpayer. 

The proposal would use $9 billion of the state’s budget surplus to provide the rebate, which is expected to cover the 51.1-cent-per-gallon gas tax for one full year of weekly fill-ups for a car with a 15-gallon gas tank.

Under the proposal, every California filer will receive a rebate—including those who don’t own or drive a car.
