Mississippi is in the middle of phasing out its income tax — the rate drops to 4% in 2026 and could reach zero by the mid-2030s. The median household income in Mississippi is approximately $52,985 — meaning a $30,000 salary is $22,985 below the state median, and $50,610 below the US national median household income of $80,610.
Mississippi's cost of living index is 85 (US average = 100), so your $25,506 net pay has the purchasing power of approximately $30,007 in an average-cost state. Cities like Jackson offer below-average cost of living, stretching your salary further than in coastal states.
