How the Calculator Works
The calculator applies your taxable income to the progressive tax brackets:
Federal Tax = (Income × Rate) for each bracket, summed together
For example, if your income is $100,000:
- $47,630 × 15% = $7,144.50
- ($95,259 - $47,630) × 20.5% = $9,878.86
- ($100,000 - $95,259) × 26% = $1,246.74
- Total federal tax = $7,144.50 + $9,878.86 + $1,246.74 = $18,270.10
Worked Example
Let's calculate the federal tax for someone earning $80,000 in 2018:
- $47,630 × 15% = $7,144.50
- ($80,000 - $47,630) × 20.5% = $6,633.39
- Total federal tax = $7,144.50 + $6,633.39 = $13,777.89
This person would owe approximately $13,777.89 in federal income tax for 2018.
