State income tax questions, answered
What is the difference between marginal and effective state income tax?
Your marginal rate taxes only the last dollar of income; your effective rate is total state tax divided by total income. In a graduated state most filers’ effective rate is well below the top marginal rate.
Does California tax all income at the top rate?
No. Graduated brackets tax only the income inside each band, so the rate you see on the last dollar is not the rate on the first dollar.
Which states have no individual income tax?
Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming collect no state individual income tax on wages.
Is this calculator tax advice?
No — this is a simplified illustration for a single filer that excludes the standard deduction, exemptions, credits, and local/city taxes. Verify with the state revenue department.
