South Carolina offers one of the most attractive retirement tax environments in the Southeast. The state does not tax Social Security benefits, provides a generous retirement income deduction, and has a low effective property tax rate. While the top marginal income tax rate is 6.40%, the retirement income deduction and other provisions mean most retirees pay very little state income tax. South Carolina’s popularity as a retirement destination — particularly in coastal areas like Hilton Head, Charleston, and Myrtle Beach — is driven in large part by these tax advantages.

How It Works

Retirement Income Deduction

South Carolina provides two key retirement income tax benefits:

  1. Under-65 deduction: Taxpayers under 65 may deduct up to $3,000 of qualifying retirement income (reduced by any Social Security deduction).

  2. Age 65+ deduction: Taxpayers 65 and older may deduct up to ~$10,000 of qualifying retirement income. This applies to pensions, 401(k) distributions, IRA withdrawals, and annuity income.

  3. Additional deduction for 65+: In addition to the retirement income deduction, South Carolina allows a separate senior deduction of up to ~$15,000 (applicable against any income, not just retirement income). The combined effect of these deductions means that many retirees with moderate incomes pay little or no state income tax.

Example: A married couple (both 65+) with $50,000 in pension income and $25,000 in Social Security:

  • Social Security: fully exempt = $0 taxable
  • Pension: $50,000 minus deductions ($20,000 retirement deduction for two taxpayers + additional senior deductions) = minimal or zero state taxable income

Military Retirement

South Carolina fully deducts military retirement pay from state income. There is no cap, making the state one of the most military-friendly in the country.

Social Security

South Carolina does not tax Social Security benefits, consistent with the majority of states.

South Carolina’s retirement income deductions and low property taxes make it competitive with no-income-tax states for retirees with moderate incomes. Only high-income retirees with large distributions pay meaningful state tax.

Tips for Minimizing South Carolina Retirement Tax

  1. Maximize the retirement income and senior deductions. Ensure you are claiming both the retirement income deduction ($10,000 for 65+) and the additional senior deduction ($15,000) on your South Carolina return.
  2. Consider the homestead exemption. South Carolina offers a homestead exemption of $50,000 in assessed value (equivalent to ~$2,000 in property value since the assessment ratio is 4%) for homeowners 65+, disabled, or legally blind. This applies to the first $50,000 of fair market value.
  3. Take advantage of the military retirement exclusion. Military retirees can deduct their full military retirement pay with no cap. This makes South Carolina one of the best states for veterans.
  4. Use Roth conversions strategically. South Carolina’s top rate of 6.40% applies to income over ~$17,330. Converting traditional IRA assets to Roth in years when income is low can reduce the state tax cost of conversion.
  5. Plan distributions to leverage the deductions. The combination of deductions means that keeping annual retirement distributions at moderate levels can result in zero or near-zero state income tax.
  6. Explore the property tax exemption for seniors. The $50,000 homestead exemption for 65+ homeowners provides property tax savings on top of the income tax benefits.
  7. Factor in the cost of living. South Carolina’s cost of living is below the national average in most areas, further stretching retirement income.
