Calculate your 2017 US federal and state income tax with this comprehensive calculator. It accounts for the 2017 tax brackets, standard deductions, and common filing statuses. The tool provides an estimate of your tax liability and shows how much you'll owe or get back.
How the 2017 US Income Tax Calculator Works
The 2017 US income tax calculator uses the progressive tax system established by the Internal Revenue Code. The calculator applies your income to the federal tax brackets and your state's tax rates to determine your total tax liability.
Federal Tax Calculation Formula
The federal tax is calculated using progressive brackets:
Federal Tax = Sum of (Taxable Income × Bracket Rate)
Where taxable income is your gross income minus deductions and exemptions.
After calculating federal taxes, the calculator applies your state's tax rates to the same taxable income. Some states have additional deductions or exemptions that affect your state tax calculation.
Note: This calculator provides an estimate. Your actual tax liability may differ based on your specific circumstances and any changes to tax laws after 2017.
Federal Tax Rates and Brackets
In 2017, the US federal income tax used these progressive brackets:
| Tax Bracket | Tax Rate |
|---|---|
| Up to $9,325 | 10% |
| $9,326 to $37,950 | 15% |
| $37,951 to $91,900 | 25% |
| $91,901 to $191,650 | 28% |
| $191,651 to $416,700 | 33% |
| $416,701 to $418,400 | 35% |
| Over $418,400 | 39.6% |
The standard deduction for 2017 was $6,350 for single filers and $12,700 for married couples filing jointly. These deductions reduce your taxable income.
State Tax Rates and Deductions
State income taxes varied significantly in 2017. The calculator includes common states with their respective tax rates and deductions. For example:
| State | Tax Rate Range | Standard Deduction |
|---|---|---|
| California | 1% to 13.3% | $4,250 (single) |
| New York | 4% to 10.9% | $8,000 (single) |
| Texas | 0% (no state income tax) | N/A |
Note that some states have additional deductions for dependents, blind individuals, or other special circumstances.
Filing Status Options
The calculator supports these common filing statuses:
- Single - For individuals who were not married or were married but filed separately
- Married Filing Jointly - For married couples who filed a joint return
- Married Filing Separately - For married couples who filed separate returns
- Head of Household - For individuals who were not married but paid more than half the cost of keeping up a home for a dependent
Your filing status affects both your federal and state tax calculations.
Worked Examples
Example 1: Single Filer with $50,000 Income
For a single filer with $50,000 gross income:
- Subtract the standard deduction: $50,000 - $6,350 = $43,650 taxable income
- Calculate federal tax:
- $9,325 × 10% = $932.50
- ($37,950 - $9,325) × 15% = $3,834.75
- ($43,650 - $37,950) × 25% = $1,372.50
- Total federal tax = $932.50 + $3,834.75 + $1,372.50 = $6,139.75
- Calculate state tax (California example):
- Subtract state deduction: $43,650 - $4,250 = $39,400 taxable income
- $39,400 × 13.3% = $5,250.20
- Total tax liability = $6,139.75 + $5,250.20 = $11,389.95
Example 2: Married Filing Jointly with $100,000 Income
For a married couple filing jointly with $100,000 gross income:
- Subtract the standard deduction: $100,000 - $12,700 = $87,300 taxable income
- Calculate federal tax:
- $9,325 × 10% = $932.50
- ($37,950 - $9,325) × 15% = $3,834.75
- ($91,900 - $37,950) × 25% = $14,112.50
- ($87,300 - $91,900) × 28% = $1,176.40
- Total federal tax = $932.50 + $3,834.75 + $14,112.50 + $1,176.40 = $20,056.15
- Calculate state tax (New York example):
- Subtract state deduction: $87,300 - $8,000 = $79,300 taxable income
- $79,300 × 6% = $4,758.00
- Total tax liability = $20,056.15 + $4,758.00 = $24,814.15
