Safeguarding American Families and Expanding Social Security Act of 2025

This bill modifies Social Security taxation and benefit calculations for high earners. It gradually reduces the percentage of wages above the Social Security tax cap that are subject to Social Security tax, from 80% in 2026 down to 0% by 2030. It increases the percentage used for the lowest earnings in benefit calculations from 90% to 95% and introduces "surplus earnings" into benefit determinations. The bill also changes cost-of-living adjustments to use a new Consumer Price Index specifically for elderly consumers. These changes would primarily affect high-earning workers and Social Security beneficiaries, particularly those becoming eligible for benefits after 2026.
