What's different about Mississippi for the self-employed
- Mississippi taxes income over $10,000 at a flat 4.0% for 2026. Two-earner married couples filing a combined return get a $10,000 zero band each, which can lower tax by up to $400.
- No local income taxes.
- For tax year 2026 Mississippi taxes individual income at 4% on taxable income above $10,000 (down from 4.4% in 2025); the first $10,000 is untaxed.
- Only two cities add a general local sales tax: Tupelo (+0.25%) and Jackson (+1% on certain sales); there is no county-level sales tax.
- The domestic LLC annual report is free but must be filed online with the Secretary of State by April 15 each year.
