President Trump's One Big Beautiful Bill Act has worsened Social Security's financial shortfall by introducing a new tax deduction that reduces taxes on benefits for many seniors. The chief actuary estimates the trust fund will lose $169 billion in revenue over a decade as a result. The Old-Age and Survivors Insurance Trust Fund is projected to run out in 2032, at which point only 78% of promised benefits could be paid. Lawmakers face a prisoner's dilemma where both parties know reform is needed but neither wants to compromise on tax increases or benefit cuts, and Trump's promise of no cuts further complicates a solution.
