Illinois state tax context
Illinois has its own state income tax (approximately 4.95% top marginal rate on wages as of 2025). This federal deduction does not automatically apply to your Illinois return — states set their own conformity rules. Check the Illinois Department of Revenue or your preparer to see whether Illinois follows this new federal deduction.
How "no tax on overtime" actually works
For tax years 2025 through 2028 the One Big Beautiful Bill Act lets you deduct the overtime premium — the extra half of time-and-a-half — from your federal taxable income.
