Self-Employed Tax Calculator — Mississippi (2026)
Self-employed in Mississippi? Your tax bill has three layers that a W-2 employee never sees in full: 15.3% self-employment tax on 92.35% of net profit, federal income tax, and Mississippi state income tax. This calculator applies all three to your 2026 net profit and shows the quarterly amount you should be setting aside. Mississippi uses a progressive income tax with 2 brackets running from 0.00% up to 4.40%, applied after a state standard deduction of $2,300.

Self-employment tax vs Mississippi income tax
Self-employment tax is federal and identical in all 50 states: 12.4% Social Security up to $184,500 of net earnings plus 2.9% Medicare with no cap. Half of it is deductible against income tax, which is why the calculator subtracts it before applying brackets.
Mississippi then taxes essentially the same profit figure at 0.00%–4.40%. On $80,000 of net profit that adds roughly $2,730 to the bill.
Mississippi has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Deductions that matter for Mississippi freelancers
Net profit — not gross revenue — drives every number here. Ordinary and necessary business expenses reduce SE tax, federal tax, and Mississippi tax simultaneously: the 2026 standard mileage rate of $0.67/mile, home-office square footage, software, equipment, professional insurance, and the self-employed health insurance deduction.
Retirement plans go further. A SEP-IRA or solo 401(k) reduces income tax (though not SE tax) and is often the largest single deduction available to a profitable agriculture contractor in Jackson.
Working for yourself in Mississippi
Mississippi's economy leans on agriculture, manufacturing, and healthcare, which shapes the contractor market around Jackson — and your fixed costs. With one-bedroom rent near $900, a freelancer needs meaningfully more gross revenue than an employee to reach the same lifestyle, because there is no employer paying half of FICA.
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.
Local and payroll taxes Mississippi adds on top
Mississippi adds no state-mandated employee payroll deduction beyond FICA, so nothing extra is taken from your gross pay at the state level.
Mississippi has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Nobody withholds these for you when you are self-employed in Mississippi. Local wage taxes, city business licences and gross-receipts style levies are yours to register for and remit alongside your quarterly federal and state estimates.
Working across a state line from Mississippi
Mississippi has no income-tax reciprocity agreements, so if you live here and work across a state line you generally file a nonresident return in the work state and claim a credit at home to avoid double taxation.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Jackson resident spending part of the year at a client site in Tennessee may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your Mississippi tax bill
Mississippi charges a 7% state sales tax, homeowners pay an average effective property tax of 0.79% of market value, and the minimum wage in force during 2026 is $7.25 an hour.
7% statewide, one of the few states that fully taxes groceries.
Income tax is only one part of a state's take. Mississippi recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. Mississippi does not tax qualified retirement income at all — pensions, 401(k) and IRA withdrawals are exempt.
Mississippi vs Tennessee on the same salary
On a $90,000 salary, a single filer keeps about $68,726 a year in Mississippi against roughly $72,145 in Tennessee — a difference of $3,419, or $285 a month.
Effective combined rates are 23.6% in Mississippi and 19.8% in Tennessee. Set that gap against living costs: index 85 here versus 91 there, with property tax at 0.79% and 0.66% respectively.
