How this is calculated
We treat the income you enter as your state taxable wage base directly, with no pre-tax deductions like 401(k) contributions or pre-tax health premiums backed out first. That keeps the estimate simple, but your real state taxable income is usually a bit lower once those are factored in.
Some states charge no income tax at all, some charge one flat rate on every dollar above their standard deduction, and others use progressive brackets that tax higher slices of income at higher rates, similar to the federal system.
Your effective state rate is simply the state tax owed divided by your income — it's always at or below the top rate that applies to your income.
