Mississippi Tax Brackets 2025 Guide – Mississippi offers one of the simplest state income tax systems in the U.S. For tax year 2025, the state uses a flat-rate structure with a generous initial exemption. Whether you’re a resident, part-year resident, or non-resident with Mississippi-source income, this guide covers everything you need to know about Mississippi tax brackets 2025, filing requirements, deductions, and how to calculate your tax liability. All information is based on the latest official data from the Mississippi Department of Revenue (MDOR).
Mississippi Income Tax Brackets and Rates for 2025
Mississippi does not use traditional multi-bracket progressive tax tables. Instead, it applies a flat rate to taxable income after a $10,000 exemption.
Here are the 2025 Mississippi income tax rates:
| Taxable Income | Tax Rate |
|---|---|
| $0 – $10,000 | 0% |
| Over $10,000 | 4.4% |
- The 4.4% rate applies only to the amount above $10,000.
- This structure is the same for all filing statuses (single, married filing jointly/combined, married filing separately, and head of family).
- Example: If your taxable income is $50,000, you pay 0% on the first $10,000 and 4.4% on the remaining $40,000 = $1,760 in state income tax.
This makes Mississippi’s system highly predictable and taxpayer-friendly compared to states with multiple brackets.
How Mississippi Taxable Income Is Calculated?
Mississippi starts with your federal adjusted gross income (AGI) and makes specific adjustments:
- You may claim the greater of the Mississippi standard deduction or federal itemized deductions (with one key difference: Mississippi does not allow a deduction for state income taxes paid).
- Subtract personal exemptions and dependent exemptions.
- The result is your Mississippi taxable income.
Important: Mississippi does not conform to all federal deductions. Always review the official MDOR checklist for taxable and deductible items.
