This bill proposes to amend the Internal Revenue Code of 1986 by creating a new exclusion for certain compensation earned from secondary employment. It allows a qualifying taxpayer to exclude "secondary employment compensation" from their gross income, thereby reducing their federal income tax liability. This exclusion also extends to federal payroll taxes, specifically social security, unemployment, and wage withholding, aiming to offer tax relief to individuals working additional jobs. To qualify, an individual must elect to designate a primary employer for whom they worked at least 2080 hours on an hourly basis during the taxable year. "Secondary employment compensation" is defined as earnings from any employer other than this designated primary employer, provided the individual makes an election for that compensation. The tax benefit is subject to an income-based phase-out , beginning when a taxpayer's modified adjusted gross income exceeds $100,000 ($150,000 for joint filers), and fully phased out $50,000 above these thresholds. Furthermore, the provision includes a sunset clause , meaning it will not apply to compensation earned in taxable years beginning five years after its enactment. To prevent adverse impacts on federal trust funds, amounts equivalent to the reduction in social security and disability revenues will be appropriated from the general fund.
