H.R. 560 — Second Job Tax Relief Act of 2025

This section establishes an exclusion from gross income, Social Security wages, Medicare wages, unemployment compensation wages, and wage withholding for secondary employment compensation received after enactment through taxable years beginning within five years after enactment. Secondary employment compensation is remuneration from an employer other than a taxpayer's elected primary employer (i.e., an hourly employer for which the taxpayer is compensated for at least 2,080 hours in the taxable year); the exclusion phases out ratably for modified adjusted gross income over $100,000 ($150,000 for married filing jointly) through a $50,000 range (to zero). The section appropriates to the Federal Old-Age and Survivors Insurance, Federal Disability Insurance, and Federal Hospital Insurance Trust Funds amounts equal to revenue losses to replicate prior transfers.
