Missouri Income Tax
Estimate state income tax on wage income using the Missouri rate you enter.
About Missouri Income Tax
This applies one flat rate — the rate you type in — to the taxable income you enter. It does not reproduce Missouri's bracket structure, deductions, exemptions or credits, and no Missouri rate is stored in the calculator. Look up the current rate and brackets with the Missouri Department of Revenue (or equivalent state tax authority) before relying on the figure.
Formula
Flat-rate estimate
Estimated tax = taxable income × the rate you entered ÷ 100
- the rate you entered
- Your own input — not a figure supplied by this calculator

Assumptions and limits
- The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- No state tax rate is built in — the rate used is the one you entered. Check the current rate and brackets with the official state tax authority.
- This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions
Does this calculator know the Missouri tax rate?
No. It deliberately ships without a state rate so it cannot show an out-of-date figure. You enter the rate; the Missouri Department of Revenue (or equivalent state tax authority) publishes the current brackets and rates.
Why is my result zero?
Because the state rate starts at 0. Enter the rate that applies to you and the estimate updates.
Does it handle graduated brackets?
No — it applies a single rate to the whole taxable income you enter. Where a state uses graduated brackets, the result is a rough upper or lower bound depending on which rate you type.
