These rates apply to single filers. Married couples filing jointly have different brackets, and other filing statuses have their own rates.

State Tax Rates

State income tax rates vary significantly across the USA. Some states have no income tax, while others have rates ranging from 1% to over 10%. The calculator includes rates for all 50 states plus Washington, D.C.

Note that some states have additional deductions or exemptions that can affect your final tax liability. The calculator provides estimates based on standard deductions for each state.

How Income Tax Calculation Works

The income tax calculation process involves several steps:

1. Subtract the standard deduction from your gross income to get taxable income.
2. Apply the progressive tax brackets to the taxable income.
3. Calculate federal income tax based on the brackets.
4. Calculate state income tax using the state's specific rates and brackets.
5. Add federal and state taxes to get the total income tax.

This calculation assumes you are not claiming any itemized deductions or credits. The actual tax you owe may be different if you have additional deductions or tax credits.

Worked Example

Let's calculate the total income tax for a single filer in California with a gross income of $60,000.

1. Federal standard deduction for single filers: $13,850
2. Taxable income: $60,000 - $13,850 = $46,150
3. Federal tax calculation:
   • $10,275 × 10% = $1,027.50
   • ($41,775 - $10,275) × 12% = $3,891.60
   • ($46,150 - $41,775) × 22% = $1,112.90
   • Total federal tax: $1,027.50 + $3,891.60 + $1,112.90 = $6,032.00
4. California state tax rate: 1% (no state income tax brackets)
5. California standard deduction: $4,483
6. State taxable income: $46,150 - $4,483 = $41,667
7. State income tax: $41,667 × 1% = $416.67
8. Total income tax: $6,032.00 + $416.67 = $6,448.67

This example shows that the total income tax for this filer would be approximately $6,448.67.
