How the 2015 US Tax System Works
The US federal income tax system in 2015 used a progressive tax rate structure, meaning higher incomes were taxed at higher rates. The taxable income was calculated after deductions and exemptions were applied.
The tax was calculated by applying the tax rates to the portions of income that fell into each bracket. For example, income in the first bracket was taxed at the lowest rate, while income in the highest bracket was taxed at the highest rate.

Example Calculation
Let's calculate the federal income tax for a single filer with $50,000 in taxable income in 2015.
Calculation Steps
- $0 - $9,075: $9,075 × 10% = $907.50
- $9,076 - $36,900: $27,825 × 15% = $4,173.75
- $36,901 - $50,000: $13,099 × 25% = $3,274.75
Total tax = $907.50 + $4,173.75 + $3,274.75 = $8,356.00
This example shows how the tax is calculated by applying the appropriate rates to each portion of income within the brackets.
