Mississippi, as of the latest available information, has a progressive income tax system with a few tax brackets. The state also offers certain deductions and credits that can reduce your taxable income. This calculator provides an estimate based on the current Mississippi tax laws, but it is not a substitute for professional tax advice.
How Mississippi Income Tax Works:
Mississippi's income tax is calculated based on your taxable income, which is your Adjusted Gross Income (AGI) minus any allowed deductions and exemptions.
Tax Brackets and Rates:
Mississippi currently uses a tiered tax rate system. The rates and income thresholds are subject to change by the Mississippi Department of Revenue.
As of recent data, the tax rates and brackets are generally structured as follows (note: these are subject to legislative changes and specific income levels):
Bracket 1: 0% on income up to a certain amount (often for lower incomes).
Bracket 2: A progressive rate (e.g., 3%) on income within a certain range.
Bracket 3: A higher progressive rate (e.g., 4%) on income within a higher range.
Bracket 4: The top rate (e.g., 4.75%) on income exceeding a certain threshold.
Important Note: Mississippi is in the process of phasing out its income tax. The top rate is scheduled to reduce over time. For the most current and accurate rates, always consult the official Mississippi Department of Revenue website or a qualified tax professional.
Deductions and Exemptions:
Standard Deductions/Itemized Deductions: Mississippi allows taxpayers to take either a standard deduction or itemize their deductions, whichever is greater. This calculator uses a simplified input for "Deductible Expenses" which can represent either.
Personal Exemptions: Taxpayers can claim exemptions for themselves, their spouse (if filing jointly), and dependents. This calculator accounts for exemptions based on the number of dependents.
The Calculation Process:
The steps involved in estimating your Mississippi income tax are:
Calculate Adjusted Gross Income (AGI): This is your gross income minus specific "above-the-line" deductions. For this calculator, we assume the "Annual Income" input is your gross income before deductions and exemptions.
Calculate Taxable Income:
Taxable Income = Annual Income - Deductible Expenses - (Exemption Amount * Number of Dependents)
Mississippi's exemption amounts can change annually. This calculator uses a simplified, representative exemption amount. For precise calculations, refer to the official Mississippi tax forms.
Apply Tax Brackets: The taxable income is then subjected to the appropriate tax rates based on the Mississippi tax brackets.
Final Tax Due: The sum of the taxes calculated for each bracket is your estimated income tax liability.

// — Mississippi Tax Calculation Logic (Simplified & Representative) —
// Note: Mississippi tax rates and exemption amounts are subject to change.
// This example uses representative rates and a simplified structure.
// The state is in the process of phasing out income tax, meaning rates are decreasing.
// For the most accurate, up-to-date information, consult the MS Dept. of Revenue.
// Representative Exemption Amount per Dependent (check current year for accuracy)
var exemptionPerDependent = 2800; // This is a placeholder, actual amount changes annually.
// Calculate Total Exemptions
var totalExemptions = dependents * exemptionPerDependent;
// Calculate Taxable Income
var taxableIncome = income – deductions – totalExemptions;
// Ensure taxable income is not negative
if (taxableIncome < 0) {
taxableIncome = 0;
}
var taxOwed = 0;
// Simplified Mississippi Tax Brackets & Rates (These are illustrative and may not reflect the absolute latest rates due to ongoing phase-out)
// Consult MS DOR for current year's specific brackets and phase-out details.
// Example progressive rates, assuming a simplified structure for illustration:
if (taxableIncome <= 1000) {
taxOwed = taxableIncome * 0.00; // First bracket often has 0% rate for lower incomes
} else if (taxableIncome <= 5000) {
// Tax on first $1000 + tax on amount above $1000
taxOwed = 0 * 1000 + (taxableIncome – 1000) * 0.03; // Example rate of 3%
} else if (taxableIncome <= 10000) {
// Tax on first $1000 + tax on $4000 (from 1000-5000) + tax on amount above $5000
taxOwed = 0 * 1000 + (5000 – 1000) * 0.03 + (taxableIncome – 5000) * 0.04; // Example rate of 4%
} else {
// Tax on first $1000 + tax on $4000 + tax on $5000 (from 5000-10000) + tax on amount above $10000
taxOwed = 0 * 1000 + (5000 – 1000) * 0.03 + (10000 – 5000) * 0.04 + (taxableIncome – 10000) * 0.0475; // Example top rate of 4.75%
}
// Mississippi's income tax rate reduction schedule needs to be considered for precise calculations.
// This calculator provides a general estimate using example rates.
// Ensure tax owed is not negative

taxOwed = 0;
