While some of these workers may be independent contractors by choice, others, like the Dynamex drivers, were forced into the classification by employers looking to save money. The National Employment Law Project estimates that employers can reduce payroll and other taxes by up to 30 percent by re-classifying employees. State-level studies on the issue, meanwhile, have uncovered extremely high misclassification rates—a series of audits in Ohio found that 47 percent of workers were misclassified. (This misclassification, not surprisingly, costs federal, state, and local governments hundreds of millions of dollars in lost tax revenues.)
