Frequently Asked Questions
Find answers to common South Carolina tax questions, including deductions for retirement income, dependent care, and education credits.
Does South Carolina allow a credit for taxes paid to another state?
Yes—SC residents may claim a credit for income tax paid to another state on the same income. Use the SC return tool to calculate the exact credit.
How do I avoid a big bill at filing time?
Increase SC withholding or make quarterly estimated payments if you have other income (investments, side gigs). The SC return tool can compute suggested estimates.
Does South Carolina have a “use tax” on online purchases?
Yes—SC imposes use tax on untaxed out-of-state purchases; it’s settled on your SC return, separate from wage withholding.
How do I model extra withholding just for a bonus?
Add a flat extra withholding amount for that pay period in this page to preview cash-flow and year-end effects.
Are there “millionaire taxes” or surcharges in SC?
SC relies on a multi-bracket PIT with a top rate (phasing downward over time); there is no separate millionaire surcharge at the state level as of 2026.
