How much should freelancers in South Carolina set aside for taxes?
As an estimate, a self-employed person in South Carolina with $50,000 of profit should set aside about 24% of that profit, rising to about 27% at $100,000. That covers federal income tax and self-employment tax, plus South Carolina state income tax. Here's where the numbers come from.

| Top rate | 6% on single-filer income over $18,230 |

Picking a planning rate for a graduated tax
South Carolina taxes each slice of income at a higher rate as you earn more, so there isn't one number. Our calculator takes a single state rate, so use your planning rate: the average South Carolina rate on your income, before state deductions and credits. Because it skips those, it leans slightly high, which is the safe direction for a set-aside.
At $50,000 of profit that's about 4.6%; at $100,000 it's about 5.3%. Don't use the top rate (6%) unless your income is above $18,230. It would make you over-save.
| Single-filer taxable income over | Rate |
|---|---|
| $0 | 0% |
| $3,640 | 3% |
| $18,230 | 6% |
