___________ does not have a taxable minimum dollar amount for employers.

Medicare Insurance requires employers to contribute a percentage of each employee's earnings, regardless of the amount. There is no minimum dollar threshold for taxable earnings, meaning that every employee's paycheck is subject to the Medicare tax from the first dollar earned. This contrasts with other payroll-related taxes that may have thresholds or limits below which no tax is assessed. By treating all levels of earnings equally with regard to taxation, Medicare Insurance ensures that all workers contribute to the program, thereby supporting the future healthcare benefits that they will receive when they become eligible.

In comparison, other options like Social Security Insurance and certain employer contributions may have specific minimum thresholds before they are applicable, and unemployment taxes often depend on payroll amounts that may exclude lower wages or certain categories of workers altogether.
