South Carolina has a mid-tier effective income tax of about 4.40% on retirement-relevant income, but it joins the majority of states in fully exempting Social Security from state tax. The state-tax bite on a typical $90k-$120k retirement income lands in the $3,960–$5,280 range annually.
What South Carolina taxes (and what it doesn’t)
South Carolina taxes retirement income (401(k) withdrawals, IRA withdrawals, pension payments) at the state's standard income-tax rate. Social Security benefits are FULLY EXEMPT from state tax — this matters because it can change your effective state-tax burden by 2-4 percentage points compared to a state that taxes SS.
State-specific note
Top rate 6.4% but $10k retirement income deduction (under 65) and $15k for 65+ keep effective rate ~4.4%.
A worked example
Worked example. A South Carolina retiree with $60,000 of pension and IRA withdrawals plus $30,000 of annual Social Security is taxed on the $60,000 of non-SS income only (SS is exempt). At the approximate 4.40% effective rate, that's about $2,640/year — roughly $220/month — owed to the state.
Should you relocate?
Whether to relocate from South Carolina for tax reasons depends on the size of your retirement income and the destination state. The math typically favors staying put unless you're at $1M+ household income or planning a 20+ year retirement that amortises the move costs.

Does South Carolina tax my Social Security?
No. South Carolina fully exempts Social Security benefits from state income tax. You'll only owe state tax on non-SS retirement income (401(k), IRA withdrawals, pensions, brokerage gains).
What's the effective state tax rate on my retirement income?
South Carolina's approximate effective rate for retirement-bracket income is 4.40%. For a $90k retirement income with $30k of Social Security, you'd owe roughly $2,640/year in state tax. Real liability varies with bracket structure, age-based exclusions, and pension carve-outs.
Should I relocate to South Carolina for retirement?
It depends on the size of your retirement income, the destination state's effective rate, and your moving costs. The state-tax differential alone is rarely the decisive factor for normal-income retirees. For households with $1M+ retirement income, multi-year tax-arbitrage savings can exceed $20k/year — enough to drive the decision.
Are pension benefits taxed differently in South Carolina?
Many states have specific carve-outs for pension income — particularly for public-sector pensions (teachers, firefighters, police, military). Top rate 6.4% but $10k retirement income deduction (under 65) and $15k for 65+ keep effective rate ~4.4%. Yearfold's calculator uses an effective-rate approximation; real liability may be lower if you qualify for a pension exclusion.
Does this apply to property tax too?
No. This page covers state INCOME tax only. Property tax in South Carolina is set by local jurisdictions (county / city / school district) and varies dramatically within the state. For a complete retirement-cost picture, consult your specific county's tax assessor.
