Updated October 8, 2026. Quick answer: For tax year 2026 Mississippi taxes nothing on the first $10,000 of taxable income and taxes the excess at 4%, according to the Department of Revenue. The same page lists 4.4% for 2025 and 3.75% for 2027.
The Mississippi rates, 2025 to 2027
| Tax year | First $10,000 | Above $10,000 |
|---|---|---|
| 2025 | 0% on the first $10,000 | 4.4% on the excess |
| 2026 | 0% on the first $10,000 | 4% on the excess |
| 2027 | 0% on the first $10,000 | 3.75% on the excess |
The Department’s page says: “2026 Excess of $10,000 of Taxable Income is taxed @ 4%”. For 2027 it says “2027 Excess of $10,000 of Taxable Income is taxed @ 3.75%”. The page itself says “Mississippi has a graduated tax rate.” It also has a sentence that calls the 2025 rate 4.4% in a 2026 context, which this page reads as describing 2025.
Deductions and exemptions listed on the page
| Filing status | Standard deduction | Exemption |
|---|---|---|
| Single | $2,300 | $6,000 |
| Married filing separately | $2,300 | $6,000 |
| Married filing jointly or combined | $4,600 | $12,000 |
| Head of family | $3,400 | $8,000 |
These charts appear on the same page and are not labeled by tax year, so this page does not claim they are 2026 amounts. The page says spouses filing a combined return can each calculate their tax separately and add the results.
A worked example
As a computed example (an illustration, not a source figure), take $100,000 of Mississippi taxable income. For tax year 2026, the first $10,000 is not taxed and the remaining $90,000 is taxed at 4%: $3,600 (computed). The same income at the 2025 rate of 4.4% would be $3,960 (computed).
What this page does not say
The statute was not read, and the page’s deduction and exemption charts carry no year label.
Common mistakes
- Applying 4% to the first dollar. The first $10,000 is taxed at 0%.
- Using the 2025 rate of 4.4% on a 2026 return.
- Assuming the 2027 rate is in effect. It is listed for the 2027 tax year.
