The Missouri schedule
Missouri DOR Employer's Tax Guide (Form 4282, Dec 2025, rev 03-2026), 2026 withholding percentage table, annual column: 0% to $1,348; 2.00%, 2.50%, 3.00%, 3.50%, 4.00%, 4.50% in $1,348 steps; 4.70% over $9,436. The guide also says supplemental wages are withheld at 4.7%. Edges are indexed amounts from a withholding table, not statute text; the statute (RSMo 143.011) could not be read (revisor.mo.gov returned only a navigation shell). Same table for all filing statuses.
Single filers

Deductions, exemptions and local tax
DOR's year-changes page lists standard deductions equal to the federal amount: $15,750 single and $31,500 married filing combined (labelled 2025 updates); 2026 amounts were not shown. Not modelled.
This page does not cover local earned-income taxes (for example in Kansas City and St. Louis); check the Missouri Department of Revenue.
What changes in 2027 (projected)
RSMo 143.011 could not be read from the Revisor site, so no 2027 rate was confirmed from a primary source. DOR's tax-year-2025 page states the 2025 rate is 4.7%. Edges are indexed each year.
The 2027 column above carries the 2026 schedule forward. That is a projection, not an enacted 2027 schedule, and it is labelled that way wherever it appears.
Worked example (2026 schedule)
A single filer with $80,000 of Missouri taxable income owes $3,579 under the 2026 schedule, an effective rate of 4.47% and a marginal rate of 4.7%. A joint filer with $150,000 of Missouri taxable income owes $6,869 under the 2026 schedule, an effective rate of 4.58% and a marginal rate of 4.7%. The 2027 projection for the same incomes is the same dollar amount ($3,579 and $6,869) because the 2026 schedule is carried forward.
Common mix-ups
- Missouri taxes income from the first dollar. The first $1,348 of Missouri taxable income (2026 withholding table) is taxed at 0%.
- Capital gains are fully taxed. DOR says 100% of capital gains reported federally can be subtracted from Missouri AGI starting 2025 (Section 143.121).
- The 2025 edges ($1,313 steps) still apply in 2026. The 2026 withholding table uses $1,348 steps with 4.7% over $9,436; $1,313 steps and $9,191 are the 2025 return table.
Method
The tool applies each bracket rate only to the slice of income inside that bracket, adds the slices and divides by income for the effective rate; the marginal rate is the rate of the bracket that contains your income. The 2027 line uses the 2026 schedule and is shown as projected. Nothing you type is sent to our servers; the maths runs in your browser. For a full paycheck including federal and payroll taxes, use the paycheck calculator, and for comparing states see the state income tax calculator.
