A sales tax approved by voters in November to fund programs that combat the homeless crisis in Los Angeles County went into effect Tuesday. The increase means people in unincorporated areas and cities that did not impose their own voter-approved sales taxes will see an increase from 9.

Beginning on Tuesday, the sales tax in Los Angeles County will increase, impacting everything from groceries to car purchases. After voters approved Measure A last November, the sales tax will increase countywide from 9.
