Experts at the Center on Budget and Policy Priorities (CBPP) reviewed the same provisions and reached a different conclusion. Their analysis notes that roughly 64 percent of beneficiaries already paid no federal tax on Social Security before enactment of the bill, primarily because their incomes fell below the existing thresholds. Consequently, only about 24 percent of recipients would see a change in their tax status if the White House estimate proves accurate. The group also highlights several factors that may reduce the number of people who benefit:
- Income limits. The deduction phases out for single filers whose modified adjusted gross income exceeds $75,000 and disappears entirely at $175,000. For couples, phase-out begins at $150,000 and ends at $250,000. Seniors with incomes beyond those ranges will not receive the full deduction, and some may lose it altogether.
- Low-income households. Retirees with minimal taxable income often have deductions and credits that already offset their liability. For those households, an additional $6,000 deduction provides no practical advantage.
- Younger beneficiaries. The administration’s 88 percent figure considers only claimants aged 65 and above, yet Social Security can be claimed as early as 62. Excluding that cohort skews the overall percentage of recipients who may still owe taxes.
In total, the CBPP estimates that the share of all Social Security recipients who will pay no federal tax on their benefits will rise, but by a margin smaller than the White House projects. The precise figure, the group contends, depends on variables such as future cost-of-living adjustments, the pace of retirements among higher-income workers, and broader economic conditions. A detailed discussion of benefit taxation thresholds is available from the Social Security Administration, which does not endorse either estimate.
The debate underscores a longstanding feature of the U.S. tax code: Social Security benefits are taxed only when a recipient’s broader income surpasses designated thresholds. Those thresholds have remained unchanged since the 1990s, meaning that wage growth and rising retirement savings have gradually increased the portion of beneficiaries subject to tax. Supporters of the One Big Beautiful Bill Act say the new deduction reverses part of that trend by updating the system for today’s retirees. Critics argue the change is narrowly targeted and may provide the largest savings to households that already have significant retirement income.
For individual taxpayers, the practical effect of the legislation hinges on three key questions: age, modified adjusted gross income, and filing status. Seniors who meet the age requirement and whose income falls below the phase-out levels will likely see a lower tax bill, though the exact amount depends on other deductions, credits, and personal circumstances. Those who are younger than 65, exceed the phase-out thresholds, or already owed no tax on benefits may notice little change.
Tax professionals advise retirees to review their projected 2025 income, including pensions, investment earnings, and required minimum distributions, to determine eligibility for the new deduction. Software updates and IRS guidance are expected to incorporate the rules during the next filing season. Until then, analysts say, projections released by either the administration or independent groups should be treated as estimates rather than guarantees.
Beyond its Social Security provisions, the One Big Beautiful Bill Act contains broader changes to the tax code, including adjustments to marginal rates and expanded credits for families. Those sections do not directly affect benefit taxation but could influence overall liability for older households.
Whether the law ultimately fulfills the administration’s claim that nearly nine in ten retirees will avoid taxes on their benefits will become clearer as 2025 returns are filed and aggregated by the Internal Revenue Service. Preliminary data are expected late next year, followed by a comprehensive report after the full filing cycle concludes.
