South Carolina does not tax Social Security benefits
If you receive Social Security in South Carolina, the state will not take a portion of those payments as income tax. South Carolina is one of the states that exempts Social Security benefits from state income tax entirely. This means your monthly Social Security check arrives without state tax withheld, and you will not owe South Carolina state income tax on those benefits when you file your state return.
The federal government may still tax your Social Security benefits depending on your total income, but that is a separate matter from state taxation. South Carolina's exemption applies only to state taxes, not federal ones.
Key Takeaways
- South Carolina does not tax Social Security income at the state level, regardless of how much you receive or your other income.
- Federal income tax may still explore to your Social Security benefits if your combined income exceeds certain thresholds, but this is separate from South Carolina state tax.
- You will not see South Carolina state tax withheld from your Social Security payments.
- Other retirement income such as pensions, 401(k) withdrawals, and IRA distributions may be subject to South Carolina state income tax.
What counts as Social Security income for tax purposes
Social Security benefits include your monthly retirement payments, survivor benefits paid to family members, and disability benefits. All of these are exempt from South Carolina state income tax. It does not matter whether you are receiving benefits as a retired worker, a spouse, a child, or a surviving family member — South Carolina treats all Social Security income the same way.
The exemption also applies regardless of your age or how much you earn from other sources. Even if you work part-time or have substantial investment income, your Social Security portion remains untaxed by the state.
Federal taxation of Social Security is different from state taxation
While South Carolina does not tax Social Security, the federal government may. Whether your benefits are taxed federally depends on your combined income, which includes your Social Security benefits, wages, interest, dividends, and other income sources. The IRS uses a formula based on your filing status and a calculation called "combined income" to determine if any portion of your benefits is taxable.
If your combined income falls below certain thresholds, none of your Social Security is taxed federally. If it exceeds those thresholds, up to 50 percent or 85 percent of your benefits may be subject to federal income tax. You can request federal tax withholding on your Social Security payments through Social Security Administration Form W-4V if you want to avoid a tax bill at the end of the year.
Other retirement income that South Carolina does tax
While Social Security is exempt, other common retirement income sources are subject to South Carolina state income tax. Distributions from traditional IRAs and 401(k) plans are taxed as ordinary income. Pension payments from your employer or a government agency are also taxable. Interest and dividends from savings accounts and investments count as taxable income.
If you are retired and receiving a mix of income sources, only the Social Security portion gets the state tax break. You will owe South Carolina income tax on the rest unless you fall below the state's income threshold for filing. South Carolina's income tax rates range from 0 percent to 7 percent depending on your income bracket.
How to report Social Security on your South Carolina tax return
When you file your South Carolina state income tax return, you will report your Social Security benefits on the return, but they will not be taxed. South Carolina Form SC1040 is the main individual income tax return form. You will list your Social Security income in the income section, but it will be subtracted out as a non-taxable item, so it does not increase your tax liability.
If you use tax preparation software or work with a tax professional, they will handle this automatically — the software knows that South Carolina does not tax Social Security and will process it correctly. You do not need to do anything special or file a separate form to claim the exemption.
When you might still need to file a South Carolina return
Even though your Social Security is not taxed, you may still need to file a South Carolina state return if you have other income. If you receive pension payments, withdraw money from an IRA, have wages from work, or earn interest and dividends, your total income from those sources might exceed South Carolina's filing threshold. The threshold varies by age and filing status.
Filing a return when you have other income ensures you pay the correct amount of state tax and may help you recover any overpayment through a refund. If Social Security is your only income, you generally will not need to file a South Carolina state return, though filing may still benefit you if you paid estimated taxes or had withholding during the year.
Frequently Asked Questions
Will I owe South Carolina state tax on my Social Security if I move to the state after retirement?
No. South Carolina does not tax Social Security benefits for any resident, regardless of when you moved to the state or where you received the benefits. The exemption applies to all Social Security income received while you are a South Carolina resident.
What if I receive both Social Security and a pension — how much state tax do I owe?
Your Social Security portion is not taxed by South Carolina, but your pension is. You will owe state income tax only on the pension amount. The tax rate depends on your total income and filing status, with South Carolina rates ranging from 0 to 7 percent.
Do I need to file a federal tax return if I only receive Social Security in South Carolina?
That depends on your combined income and filing status, not on South Carolina's rules. The federal threshold is separate. You may need to file a federal return even if you do not owe South Carolina state tax. Check the IRS website or speak with a tax professional about federal filing requirements.
Can I claim a deduction for Social Security taxes I paid while working?
No. Social Security taxes paid during your working years are not deductible on your state or federal return. However, you may be able to deduct a portion of your self-employment tax on your federal return if you were self-employed — this is a federal rule, not a South Carolina one.
