  • Illinois: Up to $10K deduction/year
  • Pennsylvania: Up to $18K deduction/year
  • California: No state deduction (but no state income tax!)

    Example (Illinois, $10K deduction):
  • State tax rate: 4.95%
  • Tax savings: $10K × 4.95% = $495/year
  • Over 18 years: $8,910+ in tax savings!

  • Key insight: Free money from state tax deduction! `
