About the State Income Tax Calculator
Nine states don't tax wages: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming. Fifteen use a single flat rate, and the rest use graduated brackets.
This uses the Tax Foundation's table of 2026 rates as of 1 January 2026: state standard deductions, personal exemptions and per-dependent exemptions or credits.
The formula
State tax = brackets applied to (income − state deduction − exemptions) − exemption credits
Worked example
Example: California income tax (2026) = $4,512
- Inputs: State: California; Filing status: Single; Income subject to state tax: $94,000; Dependents: 0.
- Formula: State tax = brackets applied to (income − state deduction − exemptions) − exemption credits
- Result: California income tax (2026) = $4,512
- State taxable income: $88,460
- Top bracket: 9.3%
Things to keep in mind
- Local income taxes (e.g. New York City, Maryland counties, Ohio cities) aren't included.
- Phase-outs of deductions or exemptions at higher incomes, state credits and mid-year law changes aren't modelled.
