Plain English
Companies and workers use Form SS-8 to officially ask the IRS whether a specific worker is legally considered an 'employee.' This determination dictates how federal payroll taxes (like Social Security) are handled for that person's income. If filed correctly, it establishes the legal basis for tax withholding between the employer and employee.
