are social security wages taxable income
Turn Accessibility Mode On. Some people have to pay federal income taxes on their Social Security benefits. This usually happens only if you have other substantial income (such as wages, self-employment, interest, dividends and other taxable income that must be reported on your tax return) in addition to your benefits.
The Social Security component of the FICA tax is regressive, meaning the effective tax rate regresses (decreases) as income increases beyond the compensation limit. The Social Security component is a flat tax for wage levels under the Social Security Wage Base (see Regular employees above).
