The tax brackets for 2013 are as follows:
| Filing Status | Tax Bracket | Tax Rate |
|---|---|---|
| Single | $0 - $8,925 | 10% |
| $8,926 - $36,250 | 15% | |
| $36,251 - $87,850 | 25% | |
| $87,851 - $183,250 | 28% | |
| $183,251 - $408,250 | 33% |
Similar brackets apply for other filing statuses, with different income thresholds.
Worked Example
Let's calculate the federal income tax for a single filer with $50,000 in taxable income:
- $8,925 × 10% = $892.50 (first bracket)
- ($36,250 - $8,925) × 15% = $3,818.75 (second bracket)
- ($50,000 - $36,250) × 25% = $3,656.25 (third bracket)
Total federal income tax = $892.50 + $3,818.75 + $3,656.25 = $8,367.50
