Estimates for tax year 2026, for informational purposes only — not tax advice. California's 2026 brackets haven't been published yet, so the most recent confirmed prior-year schedule is used as a placeholder; figures for New York, Ohio, Georgia, Virginia, Arizona, Massachusetts, Utah, Vermont, Maine, Mississippi, Missouri, Colorado, Connecticut, Delaware, Idaho, New Mexico, Oklahoma, and Oregon are drawn from secondary sources pending direct confirmation against the state's own published schedule. Consult a tax professional before filing.

Missouri self-employment tax, explained

Missouri applies the identical bracket schedule to every filing status, but because its top 4.7% bracket starts at just $9,436, nearly all profitable self-employed Missourians pay that top marginal rate on the bulk of their net income regardless of status.

Self-employment (SE) tax is the same everywhere — 15.3% of 92.35% of your net profit, split between Social Security (12.4%, up to the annual wage base) and Medicare (2.9%, uncapped). What changes by state is the income tax layer on top: Missouri has a progressive income tax with a top rate of 4.7%, applied to your taxable income after federal deductions. For filing status, Missouri's tax uses the identical bracket schedule for single and joint filers — marrying doesn't widen the brackets the way it does federally.

Missouri's 2026 figures are drawn from secondary sources (tax-data aggregators and professional publications), not a direct fetch of the state's own published schedule. They're corroborated across multiple sources but not independently confirmed — re-verify against the state's official publication before relying on this for a specific filing decision.

Frequently asked questions

What is the Missouri state income tax rate for 1099 income?

Missouri has a progressive income tax with a top rate of 4.7%. Its tax uses the identical bracket schedule for single and joint filers — marrying doesn't widen the brackets the way it does federally. See the "Missouri self-employment tax, explained" section above for how it applies to your specific numbers.

How is self-employment tax calculated?

Self-employment tax is 15.3% of your net self-employment earnings (92.35% of net profit): 12.4% Social Security up to the annual wage base, plus 2.9% Medicare on all net earnings. If your combined income exceeds the Additional Medicare Tax threshold for your filing status, an extra 0.9% applies above that threshold.

What's the difference between self-employment tax and income tax?

Self-employment tax funds Social Security and Medicare — it's the self-employed equivalent of the payroll taxes an employer would otherwise split with you. Federal (and state) income tax is separate, calculated on your taxable income after deductions like the standard deduction and the QBI deduction.
