As a single filer, you receive a standard deduction of $16,100 for 2026. Your taxable income is your gross salary minus this deduction. The federal tax brackets for single filers are narrower than for married filers — for example, the 12% bracket ends at $49,850 for single filers vs $99,700 for married filing jointly. This means single filers hit higher marginal rates sooner on the same income.
The effective tax rate for single filers in South Carolina ranges from 18.4% at $40K to 32.4% at $300K. The progressive bracket system ensures that lower earners keep a higher percentage of their income, while higher earners pay more in both absolute dollars and as a percentage.
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 | $58,418 | $61,503 | +$3,085 | +$257/mo |
| $100K | $74,965 | $80,550 | +$5,585 | +$465/mo |
| $150K | $107,511 | $116,835 | +$9,324 | +$777/mo |
In South Carolina, 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.
South Carolina uses a graduated income tax with rates of 0-6.4%. For married filers, South Carolina’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 6.4%, 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.
