Filing as married filing jointly gives you a standard deduction of $32,200 for 2026 — exactly double the single deduction of $16,100. The federal brackets are also wider: the 12% bracket extends to $99,700 (vs $49,850 single), and the 22% bracket extends to $212,900 (vs $106,450 single). This generally results in lower taxes when one spouse earns significantly more than the other.
The effective tax rate for married filers in Mississippi ranges from 12.8% at $40K to 25.3% at $300K. The wider brackets and doubled deduction mean married filers consistently pay a lower effective rate than single filers at the same gross salary (assuming one earner).
How much difference does filing status make? Here’s a side-by-side at three key salary levels (assuming one earner):
| Salary | Single Take-Home | Married Take-Home | Difference | Monthly Diff |
|---|---|---|---|---|
| $75K | $59,100 | $62,185 | +$3,085 | +$257/mo |
| $100K | $75,875 | $81,460 | +$5,585 | +$465/mo |
| $150K | $108,876 | $118,200 | +$9,324 | +$777/mo |
In Mississippi, married filing jointly consistently results in a marriage bonus at these salary levels, averaging $5,998/year. The bonus is largest at higher incomes because the doubled standard deduction and wider brackets shelter more income from higher marginal rates. This analysis assumes one earner — when both spouses have similar incomes, the bonus shrinks or may become a penalty as combined income pushes into higher brackets.
Mississippi uses a graduated income tax with rates of 4.7-5%. For married filers, Mississippi’s brackets may be wider than for single filers, similar to the federal system, though the exact ratios vary. With a moderate top rate of 5%, the difference between filing statuses is less dramatic at the state level than it is federally. Some states follow federal deductions closely while others have their own state-specific deductions and exemptions.
