AARP Social Security Resources. If you and your spouse file a joint return with a combined income below $32,000, your benefits are out of reach. For income between $32,000 and $44,000, up to 50 percent of benefits may be taxable, and up to 85 percent if combined income is more than $44,000. For more information, go to Social Security's website.
For every dollar of combined income above $34,000 ($44,000 if married filing jointly), $0.85 of Social Security benefits will become taxable â all the way up to the point at which 85% of your Social Security benefits are taxable.*. Depending on how high your âcombined incomeâ is in a given year, your Social Security benefits could be nontaxable or partially taxable (with a maximum of 85% of them being included in your taxable income for the year).
