Mississippi Income Tax Rate for 2026

Examples

Mississippi Income Tax Calculation Examples

The goal of these examples is to compare Single and Married Filing Jointly statuses at the same $80,000 annual income per person. The Single example uses $80,000 of household income, while the Married Filing Jointly example assumes each spouse earns $80,000, for a combined $160,000. The results match our All 50 States income tax calculator using $80,000 or $160,000 and the corresponding filing status.

To simplify the calculations, both examples assume full-year Mississippi residency, W-2 wages only, no dependents, and taxpayers under age 65 who are not blind or claimed as dependents. Mississippi calculates its own adjusted gross income, which equals household wages in these examples. These examples use the Mississippi standard deduction and personal exemption, with no other deductions, state adjustments, or tax credits. The federal standard deduction does not reduce Mississippi taxable income. See the All 50 States calculator for a full list of assumptions and sources.

For the married example, Mississippi calls the two-earner filing method a combined return. Each spouse's income is calculated separately on the same return, allowing each to use a $10,000 zero-rate band. We divide the joint standard deduction and personal exemption equally between the spouses. The table retains the calculator's Married Filing Jointly label and shows the combined household totals.

The standard deductions and personal exemptions shown here also appear in Mississippi's 2025 instructions and remain listed in the Department of Revenue's current guidance. The $10,000 zero-rate band is separate from both allowances. It is part of the tax calculation rather than an additional deduction from taxable income.

Looking at the table above, we can see that the same 4% tax rate applies to both Single and Married Filing Jointly statuses. The standard deduction, personal exemption, and total income taxed at 0% all double for the two-earner household. Income taxed at 4% and state income tax also double, leaving both examples with the same 3.09% effective tax rate. The combined tax equals the tax of two single filers who each earn $80,000, so this simplified comparison shows no Mississippi marriage penalty. However, a household with the same total income may have a higher effective rate if only one spouse has income or one spouse cannot fully use the separate $10,000 zero-rate band. Next, we will review the step-by-step calculations for each filing status.

Step-by-Step Example 1: Single

For a single filer with $80,000 of household income, the Mississippi standard deduction is $2,300 and the personal exemption is $6,000. With wages only and no other adjustments, subtracting both allowances leaves $71,700 of Mississippi taxable income.

• Taxable income: Subtract the standard deduction and personal exemption from household income. $\mathrm{\$80,000}-\mathrm{\$2,300}-\mathrm{\$6,000}=\mathrm{\$71,700}$
• Income subject to the 4% rate: Subtract the first $10,000, which is taxed at 0%. $\mathrm{\$71,700}-\mathrm{\$10,000}=\mathrm{\$61,700}$
• Estimated Mississippi income tax: Multiply the income above the zero-rate band by 4%. $\mathrm{\$61,700}\times 0.04=\mathrm{\$2,468}$

Mississippi effective tax rate: $2,468 divided by $80,000 of household income equals 3.09%, rounded.

Mississippi marginal tax rate: 4%, the rate applied to each additional dollar of Mississippi taxable income above the $10,000 zero-rate band in this example.

Step-by-Step Example 2: Married Filing Jointly

Now let's apply the same calculation to a married couple with $160,000 of household income. Each spouse earns $80,000 and uses $2,300 of the standard deduction and $6,000 of the personal exemption. Each has $71,700 of taxable income and a separate $10,000 zero-rate band on the combined return. The following steps show the household totals.

• Combined taxable income: Subtract the standard deduction and personal exemption from household income. $\mathrm{\$160,000}-\mathrm{\$4,600}-\mathrm{\$12,000}=\mathrm{\$143,400}$
• Combined income subject to the 4% rate: Subtract the two $10,000 zero-rate bands, or $20,000 in total. $\mathrm{\$143,400}-\mathrm{\$20,000}=\mathrm{\$123,400}$
• Estimated Mississippi income tax: Multiply the combined income above those bands by 4%. $\mathrm{\$123,400}\times 0.04=\mathrm{\$4,936}$

Mississippi effective tax rate: $4,936 divided by $160,000 of household income equals 3.09%, rounded.

Mississippi marginal tax rate: 4%, unchanged from the Single example. Both spouses already have taxable income above their individual $10,000 zero-rate bands.

Takeaway

Mississippi Income Tax Takeaways

The 4% rate does not apply to the entire paycheck: The state standard deduction and personal exemption first reduce taxable income. The first $10,000 of the remaining taxable income is then taxed at 0%.

Two earning spouses can each use the zero-rate band: At $80,000 per spouse, the combined-return calculation produces twice the Single tax and no marriage penalty in this comparison. A household with only one earning spouse cannot split that spouse's income to claim two $10,000 bands.

The effective rate shows tax as a share of household income: Both examples produce a 3.09% effective rate, below the 4% marginal rate. Results can differ with the income split between spouses, itemized deductions, additional exemptions, or tax credits.
