Income tax in Mississippi

For 2025, Mississippi exempts the first $10,000 of taxable income and taxes the rest at a flat 4.4%, down from 4.7% in 2024. The Build Up Mississippi Act (signed March 2025) continues the phase-down — 4.0% in 2026, then annual cuts toward 3.0% by 2030, with a legislated path toward eliminating the income tax entirely.
