    "context": "Your employer doesn't actually run this math by hand — payroll software uses the IRS percentage method from Publication 15-T, driven by your W-4. That's why W-4 changes (filing status, dependents, extra withholding) move your check immediately. Pre-tax 401(k) and health premiums shrink the annualized number before brackets apply, which is why raising your 401(k) by $100 costs you less than $100 of take-home.",
