H.R. 4548 — Small Nonprofit Retirement Security Act of 2025

This section makes the small employer pension plan startup costs credit (sec. 45E, i.e., 50% of qualified startup costs, up to $500 per year for three years) and retirement plan auto-enrollment credit (sec. 45T, i.e., up to $500 in the first year and $250 in each of the next two years per eligible employee) available to tax-exempt eligible employers (i.e., 501(c) organizations exempt from tax under sec. 501(a)) by treating them as credits against the employer portion of FICA taxes (sec. 3111(a)) under new sec. 3111(g), limited to the lesser of the credit amount or payroll taxes paid in the calendar year. The amendments apply to taxable years beginning after December 31, 2024. This section appropriates to the Federal Old-Age and Survivors Insurance Trust Fund and Federal Disability Insurance Trust Fund (42 U.S.C. 401) amounts equal to the reduction in Treasury revenues from these credits, with transfers from the general fund timed to replicate prior payroll tax transfers to those funds.
