The 'One Big Beautiful Bill' introduces a temporary $4,000 deduction for seniors, but its real impact on low-income retirees is questionable. While marketed as historic tax relief, the measure may fall short for those relying solely on Social Security.

For most Americans, Social Security income isn't a luxury -- it's a foundational part of their financial well-being. More than two decades of annual surveys from national pollster Gallup have consistently found that between 80% and 90% of retirees lean on their Social Security check, to some degree, to cover their expenses.

According to the SSA, recipients will pay federal income taxes on their benefits if their combined income (50% of their benefit amount plus any other earned income) exceeds $25,000/year filing individually or $32,000/year filing jointly. Instead of no tax on social security, the bill includes other tax relief for seniors.
