Up to 85% of Social Security is taxable depending on your other income and filing status. For the complete calculation, you can refer to the IRS worksheet, but for single filers, if half your Social Security plus your other income exceeds $34,000, 85% of your Social Security is taxable. 85% of your Social Security would be $24,359.
If your taxes went up $5,357 once you entered it, that would suggest a 22% tax rate, which is the rate for single filers with incomes from $40,526 to $86,375.
