Example Calculation
Let's calculate the federal income tax for a single filer with $40,000 taxable income in 2008.
- First $7,850 taxed at 10%: $7,850 × 0.10 = $785
- Next $23,150 ($40,000 - $7,850) taxed at 15%: $23,150 × 0.15 = $3,472.50
- Total tax: $785 + $3,472.50 = $4,257.50
Using the calculator, you would enter $40,000 as taxable income and select "Single" as your filing status to arrive at the same result.
