Worked Example
Let's calculate the tax for a single filer with $50,000 gross income:
- Standard deduction for single filers: $13,850
- Taxable income: $50,000 - $13,850 = $36,150
- Tax calculation:
- $10,275 × 10% = $1,027.50
- $22,440 × 12% = $2,692.80
- $13,485 × 22% = $2,966.70
- Total tax: $1,027.50 + $2,692.80 + $2,966.70 = $6,687.00
The estimated tax for this example is $6,687.00.
