State sales tax is 7% on retail sales of most tangible personal property and many services (Miss. Code Ann. Section 27-65-17). Certain items carry reduced rates — e.g., 5% on automobiles and light trucks, 1.5% on farm and manufacturing machinery, 3.5% on large construction contracts.
Each rule below is the full statewide entry, with the official source it rests on and the date it was last checked.
Income over $10,000 is taxed at a flat 4.0% for 2026 (first $10,000 exempt), down from 4.4% in 2025. Under the 2025 Build Up Mississippi Act the rate falls to 3.75% in 2027 and 3.0% by 2030, with further growth-triggered cuts toward elimination.
Mississippi's excise tax on automotive gasoline is 24 cents per gallon from July 1, 2026 through June 30, 2027, up from 21 cents for July 2025 – June 2026 under the scheduled phase-in increases. An environmental protection fee of 4/10 of a cent per gallon also applies to automotive gasoline, aviation gasoline, diesel fuel, kerosene, fuel oil and jet fuel, so state charges on gasoline total 24.4 cents per gallon; a seawall tax applies to gasoline sold in certain coastal counties. No gas-tax suspension is in effect in Mississippi. The 18.4-cent federal gasoline tax is extra.
“Automotive Gasoline will increase as follows: July 1, 2025 through June 30, 2026 21 cents July 1, 2026 through June 30, 2027 24 cents”

Groceries (SNAP-eligible food) taxed at a reduced 5% rate (cut from 7% on July 1, 2025); non-qualifying items remain at 7%. No further cut currently scheduled.
