About 40 percent of people who get Social Security have to pay income taxes on their benefits. For example:
• If you file a federal tax return as an “individual,”
and your combined income is between $25,000
and $34,000, you may have to pay taxes on up to
50 percent of your Social Security benefits.
NOTE: On the 1040 tax return, your “combined income”
is the sum of your adjusted gross income plus nontaxable interest plus half of your Social Security benefits.
From what I understand on your question, your combined income is over the $34,000 for a single individual therefore you would be subject to 85% of your Social Security benefits being taxed.
Although you’re not required to have Social Security
withhold federal taxes, you may find it easier than paying
quarterly estimated tax payments.
Also, the information above is for federal only. Some states (13 of them), also tax Social Security benefits.
