About this Mississippi paycheck estimate
With one rate, the interesting question is not which bracket you are in, because there is only one. It is how much of your pay is taxable after the deduction, and how that deduction changes with filing status. Flat 4% on taxable income. Source for the state figures: Tax Foundation 2026 State Income Tax Rates and Brackets, plus Mississippi HB 1 phase-down context (4% for 2026). Federal figures: IRS Revenue Procedure 2025-32 and Social Security Administration 2026 wage base. This page is a dated 2026 snapshot. Figures for 2027 will need a dated update, and withholding on a single pay stub may differ from this annual estimate.
At a glance for Mississippi: the shape to remember is a single state rate of 4% on taxable income, with 2 rate steps in the schedule, and a standard deduction of $2,300 single where shown.
The order of the calculation
First, annual gross pay is found from salary, or from hourly rate times hours per week times 52 weeks. Pre-tax deductions are subtracted. Federal tax uses the 2026 federal brackets and standard deduction, $16,100 single, $32,200 joint, $24,150 head of household, $16,100 separate, from IRS Revenue Procedure 2025-32. Social Security is 6.2 percent up to the 2026 wage base of $184,500. Medicare is 1.45 percent on all wages, plus 0.9 percent additional Medicare over $200,000 single, $250,000 joint and $125,000 separate. State tax is then calculated on state taxable income as described above, and the result is split by pay frequency.
Local tax: This calculator models state income tax only. If your city or county levies its own income or earnings tax, that amount is not in this result and must be added separately.
A worked example at ordinary pay
A married filing jointly earning $104,000 a year, paid semimonthly, with no pre-tax deductions, has about $4,333.33 gross per paycheck. Federal tax is about $338.33 per paycheck, Social Security about $268.67, Medicare about $62.83, and state tax about $149.00 per paycheck, giving about $3,514.50 net per paycheck and about $84,348.00 net per year in this estimate. Federal taxable income in that example is about $71,800, and state taxable income about $99,400 where a state deduction applies. Change the filing status or the pay frequency and the per-paycheck figures move even though the annual figures do not.
How a flat rate still gives a lower effective rate
Mississippi is flat at 4% above its zero-rate slice. Taxable income up to $10,000 is taxed at 0 percent, then 4% applies above that. The standard deduction is $2,300 single and $4,600 joint where shown, and it is subtracted before the rate applies.
Standard deduction in this estimate: $2,300 single and $4,600 joint, where shown. The federal standard deduction is separate and is applied to federal tax, not to state tax.
What a single rate means for different salaries
Is the top rate the rate on my whole salary?
No. In a graduated system each slice is taxed at its own rate, and in a flat system the rate applies only after the deduction. The effective rate, total state tax divided by gross pay, is the comparable figure.
Why might my real paycheck differ from this estimate?
Your W-4, your employer's withholding table, credits, itemized deductions, and any local tax or employer-specific deductions can all move the real figure. This page is an annual estimate, not a replica of one pay stub.
