First, lower income earners pay no federal income taxes on Social Security benefits, so taxation is not an issue for them. However, once a relatively low threshold level of taxable income is surpassed, somewhere between 50 to 85 percent of benefits are subject to taxation.
Of the 6.2 percent, 5.3 percent goes to pay for Social Security retirement and survivor benefits and 0.9 percent pays for disability insurance. The combined tax paid by workers and employers for disability insurance is 1.8 percent of wages, while the combined tax for retirement and survivor benefits is 10.6 percent, for a total of 12.4 percent.
