Bart must include $2,500 in his gross income for the social security payments.
To calculate the amount Bart must include in his gross income for the social security payments, we need to understand how social security benefits are taxed.
For single taxpayers like Bart, if their combined income (adjusted gross income + nontaxable interest + 1/2 of Social Security benefits) exceeds $25,000, up to 50% of their Social Security benefits can be subject to tax. If their combined income exceeds $34,000, up to 85% of their Social Security benefits can be subject to tax.
Based on the information given, Bart received $24,000 in pension payments and $5,000 of Social Security payments. Assuming he has no other income or deductions, his combined income would be $29,500. Since this amount is between $25,000 and $34,000, up to 50% of his Social Security benefits can be subject to tax.
Therefore, Bart must include $2,500 ($5,000 x 50%) in his gross income for the social security payments.
