Worked Example

Let's calculate the tax for a retired individual with $100,000 in total income and $20,000 in deductions:

1. Taxable Income = $100,000 - $20,000 = $80,000
2. First $43,906 × 15.05% = $6,586.78
3. Next $43,907 × 20.50% = $8,986.74
4. Remaining $12,187 × 26.95% = $3,278.49
5. Total Tax = $6,586.78 + $8,986.74 + $3,278.49 = $18,852.01

This example shows the progressive tax calculation for a retired individual earning $100,000 with $20,000 in deductions.
