This bill proposes to significantly increase the amount of Social Security benefits excluded from gross income by amending Section 86(c) of the Internal Revenue Code of 1986. It raises the income thresholds for taxation, specifically increasing the initial exclusion for single filers from $25,000 to $50,000 and for joint filers from $32,000 to $64,000 , with similar increases for higher income brackets. Furthermore, the legislation introduces an inflation adjustment mechanism for these new dollar amounts, which will begin for taxable years after December 31, 2026. This adjustment, based on the cost-of-living index, aims to preserve the value of the exclusion over time. The amendments are set to apply to taxable years beginning after December 31, 2025.
