It covers wages, investments, self-employment, and more, with progressive tax rates from 10% to 37%.
Key updates for 2025:
- New Schedule 1-A: For additional deductions like qualified tips (up to $25,000), overtime pay, car loan interest on passenger vehicles, and a $6,000 enhanced senior deduction (phasing out above $75,000 MAGI single/$150,000 joint).
