Mississippi vs Florida: state income tax, 2025
For reference household P1 (single, $60,000 of wages), the state income tax is at most $1,835 more in Mississippi than in Florida.
Both figures are a hypothetical full-year resident return for tax year 2025, over the same federal return, and count state income tax only. Neither is a relocation estimate: moving mid-year means two part-year returns, which this site does not figure. “Or less” means a mechanism the engine does not yet model would lower the figure; “or more” that it would raise it.

Full-year resident figures for 2025, state income tax only, with the same federal return in every column. Every figure is provisional. “Not shown” and “not figured” mean the engine will not state a number it cannot stand behind; hover for why.
Where the difference comes from
Mississippi
- Where the return starts. Builds its own base from classes of income rather than starting from a federal line.
- Rate. 2 brackets for a single filer, from 0% to 4.4%; the top rate starts at $10,000 of taxable income.Miss. Code Ann. §27-7-5; 2025 Form 80-100 instructions, "TAX RATES": "Income Tax: 0% on the first $10,000.00 of taxable income and 4.4% on taxable income in excess of $10,000.00." (checked 2026-08-05)
- Standard deduction. $2,300 single, $4,600 married filing jointly.Miss. Code Ann. §27-7-17; 2025 Form 80-100 exemption and deduction table: $4,600 married filing joint or combined and married-spouse-died, $2,300 married filing separate and single, $3,400 head of family. (checked 2026-08-05)
- Personal exemption. $1,500 per dependant.Miss. Code Ann. §27-7-21; 2025 Form 80-100 exemption table: $12,000 married filing joint or combined and married-spouse-died, $6,000 married filing separate and single, $8,000 head of family.

- Excluded from income. Retirement income.Miss. Code Ann. §27-7-15(4)(k); 2025 Form 80-100: "Social Security benefits, Railroad Retirement benefits, and retirement income from federal, state, and private retirement systems are exempt in total." (checked 2026-08-05)
Florida
- No individual income tax. Every persona owes nothing, as a computed zero.Fla. Const. art. VII, §5(a), as recited in Fla. Stat. §220.02(1): "the mandate in s. 5, Art.

What this comparison leaves out
Mechanisms the engine does not model yet. Each one is named with the direction it would move the figure, which is where every “or less” above comes from.
Mississippi
- Mississippi adjustments with no input on this return (lines 51–58, 60, 62–64 and Schedule N) and the accrued-interest part of the line 59 HSA deduction Miss. Code Ann. §27-7-18 — the figure is too high without it
- Combined return where income other than W-2 wages and unemployment, or an adjustment, has no recorded owner Miss. Code Ann. §27-7-37 — the figure is too high without it
- Mississippi itemized deductions that rest on a federal limit this engine does not apply, or on taxes paid where the federal cap binds Miss. Code Ann. §27-7-17(1) — the figure is too high without it
- Interest on U.S. and Mississippi obligations (exempt) inside 1099-INT and 1099-DIV amounts this return does not split by issuer Miss. Code Ann. §27-7-15(4) — the figure is too high without it
- Married filing separate: dependents claimed on the other spouse’s return Miss. Code Ann. §27-7-21 — the figure is too high without it
- Credit for income tax paid to another state (Form 80-160) Miss. Code Ann. §27-7-77 — the figure is too high without it
Florida
Nothing declared.
Taxes that are not income tax. Property tax, sales and excise taxes, and state payroll levies such as disability or paid-leave contributions are not counted here, and none of them is small. Federal tax is excluded because it is the same in both columns. A state income tax comparison is not a total tax burden comparison; see methodology.
