Federal Income Tax Calculation

The federal income tax is calculated using progressive tax brackets established by the IRS. The 2023 tax brackets for single filers are shown below:

Taxable Income	Tax Rate
$0 - $11,000	10%
$11,001 - $44,725	12%
$44,726 - $95,375	22%
$95,376 - $182,100	24%
$182,101 - $231,250	32%
$231,251 - $578,125	35%
$578,126+	37%

The calculator applies these rates to your taxable income, which is typically your gross salary minus standard deductions and other adjustments.

State Income Tax Calculation

State income tax rates vary significantly across the USA. For example, California has a progressive tax system with rates ranging from 1% to 13.3%, while Texas has no state income tax.

California Example

For a taxable income of $50,000 in California:

$0 - $8,932: 1% = $89.32
$8,933 - $20,959: 2% = $220.74
$20,960 - $33,003: 4% = $440.13
$33,004 - $44,199: 6.5% = $756.54
$44,200 - $50,000: 8% = $536.00
Total state tax: $2,562.73

The calculator uses the most recent state tax brackets available. For accurate results, select your specific state from the calculator options.

Worked Example

Let's calculate the taxes for a single filer with a $75,000 annual salary in California:

Federal taxable income: $75,000 - $13,850 (standard deduction) = $61,150
Federal tax:
- $0 - $11,000: $1,100
- $11,001 - $44,725: $3,573.36
- $44,726 - $61,150: $4,377.24
- Total federal tax: $9,050.60
California state tax:
- $0 - $8,932: $89.32
- $8,933 - $20,959: $220.74
- $20,960 - $33,003: $440.13
- $33,004 - $44,199: $756.54
- $44,200 - $61,150: $1,336.00
- Total state tax: $2,832.73
FICA taxes:
- Social Security: 6.2% of $142,800 = $8,908.16
- Medicare: 1.45% of $142,800 = $2,075.60
- Total FICA: $11,033.76
Take-home pay: $75,000 - $9,050.60 - $2,832.73 - $11,033.76 = $52,082.91

This example shows that after taxes and deductions, a $75,000 salary in California results in approximately $52,083 take-home pay.
