Frequently Asked Questions (FAQ)

1. How is the 2025 Mississippi income tax calculated?

For the 2025 tax year, Mississippi uses a simple system. Your income is first reduced by deductions and exemptions to get your taxable income. The first $10,000 of taxable income is taxed at 0%, and any amount over $10,000 is taxed at a flat rate of 4.4%.

2. What is the standard deduction for Mississippi in 2025?

The standard deduction depends on your filing status. For 2025, it is $2,300 for Single filers, $4,600 for those Married Filing Jointly, and $3,400 for Head of Household. Our calculator automatically applies the correct amount for you.

3. Is this Mississippi tax estimator free to use?

Yes, the tool is completely free. It’s designed to provide valuable financial information to all Mississippi residents without any cost or obligation, helping you plan your finances more effectively.

4. Can I use this calculator for my small business income?

You can use your total net income from your small business as the “Annual Gross Income” to get a solid estimate of your personal state income tax. However, remember this tool does not calculate self-employment taxes (like federal FICA).

5. Why does the calculator show an “effective tax rate”?

The effective tax rate shows the actual percentage of your total income you pay in state taxes. This is often much lower than the top 4.4% rate because deductions, exemptions, and the 0% tax bracket significantly reduce your overall tax burden.

6. Does this tool estimate my federal tax refund?

No, this estimator is specifically optimized for Mississippi state income taxes only. Federal taxes have different brackets, deductions, and rules. This tool focuses exclusively on providing an accurate MS state tax estimate.
