Unemployment worker-classification test (Miss. Code 71-5-11(J)(14)): For state unemployment insurance, the Mississippi Department of Employment Security decides whether a worker is an employee or a contractor, not the business or the worker. It uses a multi-factor common-law test covering control, the nature of the business, who supplies tools and the workplace, how long the work lasts, the method of payment, and the worker's relationship to the firm.
Rideshare (TNC) driver contractor status (2016 HB 1381; 19 Miss. Code R. 9-1.14): Rideshare drivers are independent contractors, not employees, if the company does not set required logged-in hours, does not bar them from other rideshare apps, does not assign territories, does not restrict other work, and both sides agree in writing that the driver is a contractor.
State retirement program: Mississippi Work and Save has been enacted. It is built around W-2 employers and does not cover 1099 contractors through the employer mandate.
