independent contractor

Definition from Nolo’s Plain-English Law Dictionary

A legal category of worker that is distinct and different from an employee. The key to the definition is that, unlike employees, independent contractors retain control over how they do their work. Employers are not required to withhold and pay federal, state, and Social Security (FICA) taxes on behalf of independent contractors, as they must do for employees.
