What your Mississippi paycheck actually looks like in 2026
A salary in Mississippi goes through three layers of tax before it reaches your bank account. Federal income tax, FICA (Social Security and Medicare), and the Mississippi state income tax. Get the numbers right and you can budget for rent, groceries, savings, and everything else without surprises.
How Mississippi taxes wages in 2026
Mississippi uses a flat state income tax of 4.00 percent in 2026. Every dollar of taxable income is taxed at the same rate, no matter how much or how little you earn. Flat tax states are simpler than progressive states because you do not have to figure out which bracket your last dollar falls in.
The standard deduction for a single filer in Mississippi is $2,300 in 2026, and $4,600 for married filing jointly. The personal exemption is $6,000 single or $12,000 for married filers. These come off your taxable income before the flat rate runs.
Quirk to know: Flat 4% rate as of January 2026 (was 4.4%). Scheduled to drop to 3.75% in 2027 and eventually 3% by 2030.
Federal tax and FICA hit every Mississippi paycheck
On top of Mississippi state tax, every paycheck has federal income tax, Social Security, and Medicare withheld. For 2026 the federal brackets start at 10 percent and climb to 37 percent for income above $640,600 single (or $768,700 married filing jointly). Social Security takes 6.2 percent of wages up to $184,500 in 2026. Medicare takes 1.45 percent with no cap, plus an extra 0.9 percent on wages above $200,000 single or $250,000 jointly.
For a single filer in Mississippi earning $75,000 a year, federal tax is roughly $8,000 to $8,500, Social Security is $4,650, and Medicare is $1,087. Add the Mississippi state tax (which the calculator above computes exactly), and the rest is yours.
Pre-tax deductions matter the most
If you contribute to a traditional 401(k), 403(b), HSA, or Section 125 health insurance plan, those dollars come out of your paycheck before federal AND Mississippi state income tax. Putting $200 a paycheck into your 401(k) does not reduce your take-home by $200. It reduces it by about $140 to $160, because the IRS and Mississippi are no longer taxing that money. The other $40 to $60 stays in your pocket as tax savings.
HSA contributions and Section 125 health insurance premiums go even further: they also come out before Social Security and Medicare. That makes them the most tax-efficient dollars in the entire tax code for anyone who qualifies for an HSA.
