For most retirees, South Carolina is a good place to retire for taxes. Social Security is fully exempt from state income tax, retirement income from pensions and IRAs gets substantial deductions, homeowners 65 and older qualify for a $50,000 property tax homestead exemption, and the state imposes no estate or inheritance tax. The one cost that surprises newcomers is an annual property tax on cars and trucks, so the overall picture is strong but not uniformly cheap.
How Your Retirement Income Is Taxed
Social Security benefits are fully exempt from South Carolina income tax regardless of how much you receive or what other income you have.1South Carolina Department of Revenue. Retirees – Lower Your Individual Income Tax Bill With These Five Tips That alone puts the state ahead of the handful that still tax some portion of benefits.
Other retirement income, including 401(k) withdrawals, traditional IRA distributions, and private pensions, is taxable at the state’s graduated rates, but it gets a dedicated deduction. If you are under 65, you can deduct up to $3,000 per year of qualified retirement income. Once you turn 65, that deduction jumps to $10,000 per year.2South Carolina Legislature. South Carolina Code Section 12-6-1170 – Retirement Income Deduction From Taxable Income The limits apply per person, so a married couple filing jointly where both spouses are 65 or older can deduct up to $20,000 of retirement income between them.3South Carolina Department of Revenue. SC Revenue Ruling 21-12
The Age 65 Deduction Against Any Income
Here is where the tax code gets especially generous, and where most summaries get the details wrong. Once you reach 65, you qualify for a separate deduction of up to $15,000 against any kind of South Carolina taxable income, not just retirement distributions. Wages from a part-time job, rental income, investment gains, and business income all qualify.4South Carolina Department of Revenue. Income Tax Age 65 and Older Deduction, General and Military Retirement Deductions, and Earned Income Offset
The catch is that the $15,000 is reduced dollar-for-dollar by any retirement income deduction you already claimed under the separate $10,000 provision. If you deducted $10,000 of pension income, your age 65 deduction drops to $5,000. The practical maximum per person is $15,000 total between the two deductions, not $25,000. A married couple filing jointly where both spouses are 65 or older faces a combined cap of $30,000 on the age 65 deduction, again reduced by any retirement income deductions already taken.4South Carolina Department of Revenue. Income Tax Age 65 and Older Deduction, General and Military Retirement Deductions, and Earned Income Offset
In practice, a 65-year-old couple with $30,000 in combined pension distributions and no other income can shelter all of it from state tax. Even retirees with side income from rentals or investment accounts get substantial protection.
Property Taxes on Your Home
Two features of South Carolina’s property tax system work in retirees’ favor. A primary residence is assessed at just 4% of fair market value, compared with 6% for second homes, vacation properties, and commercial real estate.5South Carolina Department of Revenue. Individual Property Tax – Chapter 5 A $300,000 home has an assessed value of $12,000, and the local millage rate applies only to that assessed amount.
On top of the low assessment, residents who are 65 or older, totally and permanently disabled, or legally blind can claim the Homestead Exemption, which provides a complete exemption from all property taxes on the first $50,000 of fair market value.6South Carolina Department of Revenue. Homestead Exemption Flyer For a $300,000 home, the exemption removes $50,000 from the calculation before the 4% ratio is applied, so only $250,000 is taxed at 4%.7South Carolina Legislature. South Carolina Code Section 12-37-250 – Homestead Exemption for Taxpayers Sixty-Five and Over or Those Totally and Permanently Disabled or Legally Blind
You apply for the exemption through your county auditor’s office with proof of age or disability and evidence that the home is your legal primary residence. Once approved, it stays in place as long as you own and live in the home. File as soon as you turn 65 so the next billing cycle reflects the reduced amount.
The Vehicle Tax That Surprises Newcomers
South Carolina taxes your car, truck, or motorcycle every year based on its value, and the bill can be substantial. This is the expense that blindsides retirees moving from states without personal property tax on vehicles. Private passenger vehicles are assessed at 6% of fair market value, and the assessed value is multiplied by your county’s millage rate to produce the annual bill.5South Carolina Department of Revenue. Individual Property Tax – Chapter 5
Millage rates vary significantly by county, so two identical vehicles garaged in different parts of the state produce different tax bills. A newer car worth $30,000 might generate several hundred dollars of tax in a lower-millage county and noticeably more in a higher-millage area. The tax decreases as the vehicle depreciates but never disappears while you own the car. If you are coming from a state that charges only a flat registration fee, build this recurring cost into your retirement budget.
Sales Tax and the Exemptions Retirees Use
The statewide sales tax rate is 6%, applied to most retail purchases including clothing, electronics, and restaurant meals.8South Carolina Department of Revenue. Sales Tax Index Counties can add local option taxes on top of the state rate when voters approve them, so the total at the register varies by location, often landing in the 7% to 8% range.
Two exemptions matter for retirees on a fixed budget. Unprepared groceries, essentially anything you could buy with federal food assistance benefits, are exempt from the 6% state sales tax, though local option taxes may still apply unless the local tax law provides its own exemption.9South Carolina Department of Revenue. Chapter 21 – Unprepared Food Exemption Prescription medications sold by prescription are also exempt from state sales tax.10South Carolina Department of Revenue. SC Revenue Ruling 03-2 Over-the-counter medications and prepared or restaurant food are taxed at the full combined rate.
No Estate or Inheritance Tax
South Carolina imposes no state estate tax and no inheritance tax. The estate tax statute is tied to the old federal state death tax credit, which was effectively eliminated in 2001; because the credit is zero, the state tax is zero.11South Carolina Legislature. South Carolina Code of Laws Title 12, Chapter 16 – Estate Tax Heirs receiving assets from a South Carolina resident face no state tax regardless of the estate’s size or their relationship to the person who died. The only death-related tax exposure is at the federal level, where the current exemption exceeds $13 million per person.
A Note for Military Retirees
Under current law, a military retiree of any age with earned income (wages or self-employment) can deduct military retirement pay up to $17,500, provided the deduction does not exceed the earned income amount. At 65, a separate deduction allows up to $30,000 of military retirement income to be excluded.4South Carolina Department of Revenue. Income Tax Age 65 and Older Deduction, General and Military Retirement Deductions, and Earned Income Offset Legislation has been introduced that would eliminate state income tax on military retirement pay entirely for tax years beginning after 2025.12South Carolina Legislature. 2025-2026 Bill 64 – Income Tax Deduction If you are weighing a move for military retirement reasons, check the current status before relying on either figure.
If You Move Partway Through the Year
You have a choice in how to file your first state return. You can file as a full-year resident, report all your federal taxable income, and claim a credit for taxes paid to the state you left. Or you can file using Schedule NR and include only the income earned while you were a South Carolina resident or from South Carolina sources.13South Carolina Department of Revenue. IIT FAQs The state lets you pick whichever method produces the lower bill. Run the numbers both ways, or have a preparer do it, because the better method depends on when during the year you moved and how your income was distributed across the months.
