Eligible FLSA overtime premium may qualify for a 2025–2028 federal deduction, capped at $12,500 for single filers before the MAGI phaseout. These examples assume eligibility. Overtime is still wages; FICA and modeled state taxes apply, and employer withholding does not automatically disappear. Choose eligibility and paid weeks.
