2015 US Federal Income Tax Brackets

The 2015 US federal income tax brackets are progressive, meaning higher incomes are taxed at higher rates. The brackets differ based on your filing status:

Single Filers

Taxable Income Tax Rate
$0 - $9,075 10%
$9,076 - $36,900 15%
$36,901 - $89,350 25%
$89,351 - $186,350 28%
$186,351 - $405,100 33%
$405,101 - $406,750 35%
$406,751+ 39.6%

Married Filing Jointly

Taxable Income Tax Rate
$0 - $18,150 10%
$18,151 - $73,800 15%
$73,801 - $148,850 25%
$148,851 - $226,850 28%
$226,851 - $405,100 33%
$405,101 - $457,600 35%
$457,601+ 39.6%

The calculator uses these brackets to compute your tax liability based on your income and filing status.

How the Tax Calculator Works

The calculator applies your income to the tax brackets progressively. Here's how it works:

  1. The calculator first determines which tax bracket your income falls into based on your filing status.
  2. It calculates the tax owed in the highest bracket by multiplying your income by the highest applicable rate.
  3. It then subtracts the income threshold for that bracket to find the taxable amount in that bracket.
  4. This process repeats for each lower bracket until all income is accounted for.
  5. The calculator sums all the taxes calculated from each bracket to provide your total federal income tax.

Tax Calculation Formula

The formula used is:

Tax = (Income × Rate) - (Threshold × Rate)

Where:

  • Income is your total taxable income
  • Rate is the tax rate for the current bracket
  • Threshold is the income threshold for the current bracket

The calculator uses standard 2015 tax brackets and does not include state taxes, deductions, or credits beyond the standard deduction.

Worked Examples

Let's look at two examples to see how the calculator works with different incomes and filing statuses.

Example 1: Single Filer with $50,000 Income

For a single filer with $50,000 taxable income:

  1. $9,075 at 10% = $907.50
  2. ($36,900 - $9,075) × 15% = $3,886.25
  3. ($50,000 - $36,900) × 25% = $3,325
  4. Total tax = $907.50 + $3,886.25 + $3,325 = $8,118.75

Example 2: Married Filing Jointly with $100,000 Income

For a married couple filing jointly with $100,000 taxable income:

  1. $18,150 at 10% = $1,815
  2. ($73,800 - $18,150) × 15% = $8,293.75
  3. ($100,000 - $73,800) × 25% = $6,825
  4. Total tax = $1,815 + $8,293.75 + $6,825 = $16,933.75

These examples show how the progressive tax system works in the 2015 tax year.
