Formula Used
The federal income tax is calculated using progressive tax brackets. The formula used is:
Tax Calculation Formula
Tax = Σ (Income in Bracket × Bracket Rate) for each applicable bracket
The 2017 tax brackets and rates for federal income tax are as follows:
| Filing Status | Tax Bracket | Tax Rate |
|---|---|---|
| Single | $0 - $9,325 | 10% |
| $9,326 - $37,950 | 15% | |
| $37,951 - $91,900 | 25% | |
| $91,901 - $191,650 | 28% | |
| $191,651+ | 33% |
For married filing jointly, the brackets are higher, and the rates apply to the combined income of both spouses.
Worked Example
Let's calculate the federal income tax for a single filer with $50,000 in taxable income in 2017.
- $9,325 × 10% = $932.50 (first bracket)
- ($37,950 - $9,325) × 15% = $4,225.75 (second bracket)
- ($50,000 - $37,950) × 25% = $3,072.50 (third bracket)
- Total tax = $932.50 + $4,225.75 + $3,072.50 = $8,230.75
Using the calculator, you would enter $50,000 as the taxable income and select "Single" as the filing status. The calculator will display the total tax of $8,230.75 and show the breakdown by bracket.
Interpreting Results
The calculator provides several key pieces of information:
- Total Tax Owed: The total amount of federal income tax you would owe based on your taxable income and filing status.
- Effective Tax Rate: The average tax rate applied to your taxable income, calculated as (Total Tax ÷ Taxable Income) × 100.
- Tax Breakdown by Bracket: A detailed view of how much tax is owed in each tax bracket, showing the progressive nature of the tax system.
This information can help you understand how your taxable income is taxed and how changes in income or filing status might affect your tax liability.
