Second Job Tax Relief Act of 2025

This bill allows qualifying workers to exclude income from a secondary job from their taxable income and payroll taxes. To qualify, workers must designate a primary employer (based on hourly work ≥2,080 hours) and earn secondary income below phase-out thresholds ($100,000 individual/$150,000 married joint filers). The exclusion phases out for income above these thresholds and expires after five years. It directly affects workers with a second job who meet the primary employer requirement, changing how secondary job earnings are taxed under the Internal Revenue Code.
