2015 US Federal Tax Brackets

The 2015 federal income tax rates were progressive, meaning higher incomes were taxed at higher rates. The brackets are as follows:

10% on first $9,150 15% on next $28,950 ($9,151 - $38,100) 25% on next $52,300 ($38,101 - $80,400) 28% on next $100,000 ($80,401 - $180,400) 33% on next $250,000 ($180,401 - $430,400) 35% on amounts over $430,400 39.6% on long-term capital gains

The calculator applies these rates to your income based on your filing status.

Filing Status Options

Your filing status determines which tax brackets and deductions apply. The options are:

Single - For individuals who were not married or were married but filed separately
Married Filing Jointly - For married couples filing a joint return
Married Filing Separately - For married couples who filed separately
Head of Household - For individuals who qualify as the head of a household

Select the option that matches your 2015 tax situation.

Standard Deduction Amounts

The standard deduction reduces your taxable income. For 2015, the amounts were:

Single: $6,300 Married Filing Jointly: $12,600 Married Filing Separately: $6,300 Head of Household: $9,250

If your income is below these amounts, your taxable income is $0.

Example Calculation

Let's calculate the tax for a single filer with $50,000 income:

Taxable income = $50,000 - $6,300 (standard deduction) = $43,700
First $9,150 taxed at 10% = $915
Next $28,950 taxed at 15% = $4,342.50
Remaining $8,600 taxed at 25% = $2,150
Total tax = $915 + $4,342.50 + $2,150 = $7,407.50
Effective tax rate = ($7,407.50 / $50,000) × 100 = 14.81%

This example shows the progressive nature of the tax system - higher income earners pay a higher percentage of their income in taxes.
