The purpose of this legislation, known as the "Gig Is Up Act," is to change how large businesses handle payroll taxes for independent contractors. Specifically, it aims to ensure that these businesses with significant revenue are required to withhold payroll taxes from payments made to independent contractors, similar to how they would for regular employees. Key provisions of the act include a requirement for businesses that earn at least 00 million in gross receipts and hire at least 10,000 independent contractors to treat payments to these contractors as wages for tax purposes.
