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.
Thatâs because, if your âcombined incomeâ is in the applicable range, each additional dollar of income is not only taxed at your regular tax rate, it also causes an additional $0.50 or $0.85 of Social Security benefits to be 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).
