Frequently Asked Questions
How are stock RSUs/option exercises taxed by South Carolina?
When RSUs vest or options are exercised, the income is usually W-2 wages taxable by SC if sourced to work performed in the state. Capital-gain portions later may receive SC’s long-term gain exclusion—estimate with Schedule D.
Can I model multiple jobs in this wage tool?
Yes—enter combined annual wages here, or run separate scenarios per job. Ensure each employer’s withholding is aligned to avoid under-withholding.
Are moving expenses deductible for SC?
Generally not, unless qualifying military moves. SC follows its own modification rules; most taxpayers won’t see a state deduction for moving costs.
Does South Carolina tax investment interest/dividends?
Yes—in SC they flow from federal AGI with state modifications. Use Schedule B to total interest/dividends and then include in the SC return.
What’s the deal with age-65 deductions in SC?
South Carolina provides an age-65 deduction (in addition to a larger retirement-income deduction for those 65+). The interaction of these deductions can be complex; use the state return tool to calculate precisely based on your mix of wages, retirement income, and other income.
