How Much of Someone’s Social Security Benefit is Taxed?

First, individual taxpayers or taxpaying married couples must add up their “modified adjusted gross income.” This is their taxable income, plus their tax-exempt income, plus half of their Social Security benefits. If this figure exceeds certain income levels, a portion of Social Security benefits is taxed.

Next, a worksheet is completed to determine the amount of Social Security benefits that is taxable. This worksheet can be found in the annual instructions package for tax forms available online in the “Forms and Publications” section of Under current law, in 2017, the income levels where income taxes on Social Security benefits apply are as follows:

• 50% of Social Security Benefits Taxed – $25,000 to $34,000: Single and Head of Household and $32,000 to $44,000: Married filing jointly

• 85% of Social Security Benefits Taxed – Over $34,000: Single and Head of Household  and over $44,000: Married filing jointly
