South Carolina Quarterly Taxes for Freelancers

South Carolina has a three-bracket income tax system where the first $3,640 is tax-free, followed by 3% up to $18,230, and 6% above that. The 6% top rate is among the higher rates in the Southeast. South Carolina's standard deduction of $8,350 for single filers is moderate. No South Carolina city charges a local income tax on wages. South Carolina has been discussing income tax reform to reduce the top rate, and some reductions have occurred in recent years. Compared to neighboring North Carolina (3.99% flat, trending lower) and Georgia (5.19% flat), South Carolina's 6% top rate is higher. Workers in Charleston and Greenville — fast-growing metros attracting remote workers from higher-tax states — still benefit from no local city income tax.
