Missouri Paycheck Calculator 2026

How Missouri payroll taxes impact your 2026 paycheck

Missouri uses a progressive income tax system with rates ranging from 0% up to 4.8% for the highest earners. Different pieces of your income fall into each bracket, so your effective rate is lower than your top marginal rate.

Because we already maintain federal, FICA, and Missouri withholding tables for every filing status, the calculator instantly shows both per-paycheck and annual net pay. Toggle between salary and hourly pay, include pre-tax deductions such as 401(k), HSA, or health insurance, and watch the tool recompute your Missouri take-home pay immediately.

How to use the Missouri paycheck calculator

1. Select salary or hourly pay and enter your gross income.
2. Choose Missouri as your state (using ?state=MO in the URL fills it in automatically).
3. Pick your pay frequency and filing status, then add any 401(k), HSA, or health insurance deductions.
4. Click “Calculate My Paycheck” and review the per-paycheck plus annual summary, including federal, Missouri, and FICA withholding.

Missouri local taxes and paycheck adjustments

Many Missouri workers also face local payroll or city wage taxes. Use your latest pay stub to see those percentages and add them as post-tax deductions inside the calculator. This is especially important if you work in a major metro area or a school district that levies its own earned income tax.

2026 planning tips for Missouri employees

• Update your W-4 (and any Missouri-specific withholding form) if you picked up a second job, got married, or expect significant itemized deductions in 2026.
• Leverage pre-tax benefits—every dollar you contribute to a 401(k) or HSA reduces both federal and Missouri taxable income (unless you live in a no-tax state).
• Track your year-to-date taxable wages. Once you hit the Social Security wage base, your take-home pay will jump because OASDI withholding stops for the rest of the year.
