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.

Mississippi self-employment tax, explained

Mississippi is on a legislated glide path toward eliminating its income tax entirely, with the current 4% flat rate (above a $10,000 zero-tax floor) scheduled to keep falling automatically each year through at least 2030.

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: Mississippi has a progressive income tax with a top rate of 4%, applied to your taxable income after federal deductions. For filing status, Mississippi's tax uses the identical bracket schedule for single and joint filers — marrying doesn't widen the brackets the way it does federally.

Mississippi'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 Mississippi state income tax rate for 1099 income?

Mississippi has a progressive income tax with a top rate of 4%. 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 "Mississippi 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.
