What is the Mississippi state income tax?
Mississippi state income tax is a tax on income earned by individuals. It is collected by the Mississippi Department of Revenue and helps fund state services.
Mississippi uses a graduated income tax structure. For tax year 2025, the first $10,000 of taxable income is taxed at 0%, and taxable income over $10,000 is taxed at 4.4%. If you are married filing jointly, the first $10,000 of each spouse’s taxable income is exempt before the 4.4% rate applies to remaining income.

Mississippi standard deduction
Mississippi allows you to choose between claiming the standard deduction for your filing status or itemizing individual non-business deductions on Schedule A, whichever provides the greater tax benefit. Mississippi generally allows the same itemized deductions used for federal income tax purposes, except Mississippi income taxes are not deductible on your Mississippi itemized deduction schedule.
For tax year 2025, Mississippi standard deduction amounts by filing status are:
| Filing Status | Standard Deduction |
|---|---|
| Single | $2,300 |
| Head of Family | $3,400 |
| Married Filing Separately | $2,300 |
| Married Filing Jointly or Surviving Spouse | $4,600 |
See the Mississippi Department of Revenue for rules on dividing deductions between spouses and proration for nonresidents and part-year residents.
Mississippi exemptions
Mississippi allows personal exemption amounts that reduce your Mississippi taxable income. For tax year 2025, exemption amounts by filing status include $6,000 for single filers and married filing separately, $8,000 for head of family filers (with at least one qualifying dependent), and $12,000 for married filing jointly or surviving spouse returns.
You may also claim a $1,500 exemption for each dependent other than yourself or your spouse, plus additional $1,500 exemptions for taxpayers or spouses who are age 65 or older or blind. Learn more about Mississippi exemptions and deductions on the Department of Revenue website.
Mississippi tax changes for 2025
For tax year 2025, Mississippi taxes taxable income over $10,000 at 4.4%, with the first $10,000 taxed at 0%. Under Mississippi’s ongoing income tax reduction schedule, the rate on income over $10,000 is scheduled to decrease in future years — for example, to 4% for tax year 2026 and 3.75% for tax year 2027.
Mississippi generally follows many federal tax rules, but Mississippi has its own exemptions, deductions, and credits that can make your Mississippi return different from your federal return. Federal tax law changes may require you to report IRS adjustments to the Mississippi Department of Revenue. See 2025 Mississippi tax legislation and the individual income tax FAQs for details.
