Income Tax Usa Calculator 2014

Calculate your 2014 US federal and state income tax with this free online calculator. The tool uses the 2014 tax brackets, standard deductions, and tax credits to provide an accurate estimate of your tax liability. Simply enter your income and filing status, and the calculator will compute your federal and state taxes, as well as your effective tax rate.

How the 2014 US Income Tax Calculator Works

The 2014 US income tax calculator estimates your tax liability based on the following key components:

Gross income (wages, salaries, tips, etc.)
Filing status (single, married filing jointly, etc.)
State of residence (for state income tax)
Standard deduction (reduces taxable income)
Federal and state tax brackets
Tax credits (reduce tax liability)

The calculator uses progressive tax brackets, meaning higher income levels are taxed at higher rates. For example, the first $9,075 of taxable income is taxed at 10% for single filers in 2014, while income above $36,900 is taxed at 39.6%.

Formula Used

Taxable Income = Gross Income - Standard Deduction

Federal Income Tax = Sum of (Taxable Income × Tax Rate for each bracket)

State Income Tax = Sum of (Taxable Income × State Tax Rate for each bracket)

Total Income Tax = Federal Income Tax + State Income Tax

Effective Tax Rate = (Total Income Tax / Gross Income) × 100

2014 Federal Income Tax Brackets

The 2014 federal income tax brackets are as follows:

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

Married filing jointly filers have higher brackets, with the first bracket starting at $18,150. The standard deduction for single filers in 2014 was $6,200, while married filing jointly filers could claim $12,400.

State income tax rates varied significantly in 2014. Some states had no income tax, while others had rates as high as 9.3%. The calculator includes common states with income taxes:

Example Calculation

Let's calculate the 2014 income tax for a single filer with $50,000 gross income in California:

Standard deduction: $8,104
Taxable income: $50,000 - $8,104 = $41,896
Federal tax:
- $9,075 × 10% = $907.50
- ($36,900 - $9,075) × 15% = $3,883.75
- ($41,896 - $36,900) × 25% = $1,224.00
- Total federal tax: $907.50 + $3,883.75 + $1,224.00 = $6,015.25
California state tax:
- First $8,104 taxed at 1% = $81.04
- Next $10,212 taxed at 2% = $204.24
- Next $10,212 taxed at 4% = $408.48
- Next $10,212 taxed at 6% = $612.72
- Next $10,212 taxed at 8% = $816.96
- Remaining $2,976 taxed at 9.3% = $276.44
- Total state tax: $81.04 + $204.24 + $408.48 + $612.72 + $816.96 + $276.44 = $2,399.88
Total income tax: $6,015.25 + $2,399.88 = $8,415.13
Effective tax rate: ($8,415.13 / $50,000) × 100 = 16.83%

This example shows that a single filer with $50,000 income in California would owe approximately $8,415 in federal and state taxes, for an effective tax rate of 16.83%.
