The FICA tax is considered a regressive tax on income with no standard deduction or personal exemption deduction. It is imposed on only the first $113,700 of gross wages in 2013 and $117,000 in 2014. The tax is not imposed on investment income such as interest and dividends. For 2014, the employee's share of the Social Security portion of the FICA tax is 6.2% of gross compensation up to a limit of $117,000 of gross compensation (resulting in a maximum Social Security tax of $7,254).
So, for a married couple with an income (adjusted as described above) less than $32,000, none of their Social Security benefits are taxable at the federal level. In the income range $32,000 to $44,000, between 50 to 85 percent of Social Security benefits may be taxable at the appropriate marginal tax rate. Above $44,000 in adjusted income, 85 percent of benefits may be taxable.
