US State Income Tax Calculator for State Tax, Refunds, and Custom Rates
In simple words
Estimate the state income tax, refund, or amount owed for your state using a preset or custom rate.
State income tax is the tax a state charges on your earnings. Not every state has one. Some states have no broad wage income tax. Others use a flat rate or progressive brackets. This calculator estimates state income tax for all states plus a custom option.
The calculator starts with your annual income. You can subtract state deductions or adjustments. Then it applies a preset or custom rate. Next it subtracts state tax credits. Finally it compares the result with state tax withheld. You see refund, amount owed, and effective rate.
Preset rates are simplified planning rates. They are not full bracket-by-bracket calculations. Use the custom rate field if you know your exact rate. This works well for flat-tax states, local estimates, or payroll planning. The calculator will use your rate instead of the preset.
A deduction reduces the income you pay tax on. A credit reduces the tax after it is calculated. Some states offer credits for dependents, rent, property tax, or education. Enter the credits you expect. Confirm eligibility with your state tax agency.
Withholding decides whether you get a refund or owe money. Withholding is the state tax taken from your paycheck. If withholding is more than your state tax, you get a refund. If it is less, you may owe money. This helps you review payroll withholding.
States without a wage income tax still have other taxes. They may have sales tax, property tax, or business taxes. Washington and New Hampshire have special rules too. The calculator treats these states as zero for wage income. That does not mean the state has no taxes at all.
Flat-tax states look simple but still have details. Credits, exemptions, and local taxes can apply. Progressive states tax different income parts at different rates. This calculator uses one planning rate for simplicity. For filing, use official state tables or tax software.
People search for state income tax calculator and state tax refund calculator. Many compare California, New York, Texas, or Florida. This tool is useful before moving or taking a job. A no-income-tax state may show zero state wage tax here. But compare the full cost of living too.
Part-year residents and remote workers need care. State tax can depend on where you live and where you work. Some states have reciprocal agreements. Others use convenience-of-employer rules. A simple calculator is a first step, not final advice.
In short, this tool gives a fast state tax estimate. It shows tax after credits, refund, or amount owed. It helps employees, movers, and remote workers plan. Use the result as a starting point. Verify the final amount with your state tax agency.
Frequently asked questions
How does the US state income tax calculator work?
It subtracts state deductions from annual income, applies a preset or custom state tax rate, subtracts state credits, and compares the estimate with state tax withheld.

Which states have no broad state wage income tax in this calculator?
The calculator treats Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming as no-broad-wage-income-tax states for simplified planning.
Can I enter my own state tax rate?
Yes. Enter a custom percentage in the custom state tax rate field. The calculator will use that rate instead of the preset planning rate.
