What is the threshold income for Social Security benefits to be partially taxable for a Single, Head of Household, or Qualified Widow filer?

The threshold income for Social Security benefits to be partially taxable for a Single, Head of Household, or Qualified Widow filer is indeed set at the range of $25,001 to $34,000. This is important to understand because it determines whether a taxpayer's Social Security benefits will be subject to federal income tax.

For individual filers, if the combined income (which is calculated as adjusted gross income + nontaxable interest + half of Social Security benefits) exceeds $25,000, a portion of the Social Security benefits may become taxable. If the combined income exceeds $34,000, then a higher percentage of the benefits could be taxed. Therefore, understanding these thresholds helps taxpayers recognize their tax liabilities accurately.

Considering the choices, the first range, $0-$25,000, does not capture the thresholds where Social Security benefits begin to be taxable, making it inappropriate as the correct answer. The other selected ranges either fall above or below the correct thresholds needed for accurate taxation of Social Security benefits.
