LOS ANGELES—For 30 years, Modesto Alejandro Vasquez has supported his family of four by working as a janitor in a downtown office building here. In 2014, he made about $30,000.
Earning 25% above the federal poverty level in costly Southern California, Mr. Vasquez looks forward to this time of year, when a tax refund puts extra cash in his pocket. He said he used the money—$6,000 this year—to pay off debts and repair a computer for his daughter.
