How Federal Income Tax Works

Federal income tax is calculated by applying the tax rates to each income bracket. The taxable income is divided into brackets, and each portion is taxed at the corresponding rate. The total tax is the sum of the taxes on each bracket.

Tax = (Income in 10% bracket × 10%) + (Income in 15% bracket × 15%) + ... + (Income in 35% bracket × 35%)

For example, if you earn $50,000 as a single filer:

$8,500 at 10% = $850
$26,000 at 15% = $3,900
$8,500 at 25% = $2,125
Total tax = $850 + $3,900 + $2,125 = $6,875

Worked Examples

Example 1: Single Filer with $40,000 Income

For a single filer with $40,000 taxable income:

$8,500 at 10% = $850
$26,000 at 15% = $3,900
$5,500 at 25% = $1,375
Total tax = $850 + $3,900 + $1,375 = $6,125

Example 2: Married Filing Jointly with $80,000 Income

For a married couple filing jointly with $80,000 taxable income:

$17,000 at 10% = $1,700
$52,000 at 15% = $7,800
$11,000 at 25% = $2,750
Total tax = $1,700 + $7,800 + $2,750 = $12,250

Frequently Asked Questions
