Understanding the SC Non-Resident Withholding Tax on Real Estate Sales

South Carolina is one of the most popular destinations in the country for vacation homes, beachfront rentals, and out-of-state real estate investments. However, when retirees, snowbirds, or out-of-state investors decide to sell their property in Myrtle Beach, Hilton Head, or Greenville, they are often blindsided at the closing table by a massive tax deduction known as the Non-Resident Withholding Tax.

Because non-residents do not live in South Carolina, the state government worries that out-of-state sellers will pocket their real estate profits, return to their home state, and never file a South Carolina income tax return to pay the capital gains tax they owe. To prevent tax evasion, the law forces the buyer and the closing attorney to withhold a hefty percentage of the seller's money on closing day and send it straight to the state capital.

Fortunately, this withholding is not a permanent penalty-it is simply an estimated prepayment of state taxes. Understanding how the rates are calculated, how to use the Seller's Affidavit to dramatically lower the withholding amount, and which exemptions wipe out the tax completely can save you tens of thousands of dollars at closing.

Step-by-Step Process for Non-Resident Sellers at Closing

If your permanent legal domicile is outside of South Carolina on the day you sell your property, your closing attorney will guide you through this mandatory statutory process.

Step 1: Calculate Your True Capital Gain Before Closing

Do not let the closing attorney withhold tax based on the total sales price of your property! Gather your original purchase closing statement and all receipts for major capital improvements (such as a new roof, HVAC system, or room addition) plus your current realtor commissions to determine your actual net profit (capital gain).

Step 2: Complete and Sign the Seller's Affidavit (Form I-295)

Before closing, your real estate attorney will provide you with Form I-295, South Carolina, Department of Revenue, Seller's Affidavit Nonresident Seller Withholding. On this sworn legal document, you will state whether you are a resident or non-resident, claim any applicable exemptions, or declare your exact calculated capital gain.

Step 3: The Closing Attorney Withholds the Funds on Form I-290

At the closing table, the attorney deducts the required percentage from your seller proceeds and prepares Form I-290, South Carolina, Department of Revenue, Nonresident Real Estate Withholding. Technically, the buyer signs this form as the statutory withholding agent, and the closing attorney remits the check to the South Carolina Department of Revenue, Columbia by the 15th day of the following month.

Step 4: File a Non-Resident SC Tax Return to Claim Your Refund

Because the withholding calculation at closing does not allow you to apply South Carolina's generous 44% net capital gain deduction, almost every out-of-state seller has too much money withheld. The following spring (or earlier via an amended withholding form), you will file a South Carolina Non-Resident Income Tax return to calculate your true tax liability and get a refund check for the overpayment.

Breaking Down the Statutory Withholding Rates (7% vs. 5%)

Under S.C. Code Ann. § 12-8-580, the amount withheld depends on two factors: whether the seller is an individual or a corporation, and whether the seller signs the gain affidavit. While people often confuse the numbers, the historical statutory structure sets a 7% rate for non-resident individuals, partnerships, trusts, and estates (which the Department of Revenue adjusts to match South Carolina's current top marginal individual income tax rate, such as 6% or 5.21% depending on the tax year's legislative schedule) and a flat 5% rate for non-resident corporations.

Here is why signing the Form I-295, South Carolina, Department of Revenue, Seller's Affidavit Nonresident Seller Withholding is critical: If you refuse to sign the affidavit stating your gain, the law forces the closing attorney to withhold the percentage on the entire amount realized (the gross sales price minus selling expenses). If you sell a house for $500,000, withholding on the full price is devastating. If you sign the affidavit proving you bought the house for $400,000 and only made a $100,000 gain, the percentage is only applied to the $100,000 profit. Furthermore, under principles established in Ellis v. South Carolina Tax Commission, 280 S.C. 65 (SC Supreme Court 1983), real estate gains and losses are strictly sourced to the state where the physical property is located, meaning non-residents must account for South Carolina property gains accurately.

Exemptions to the Withholding Tax

Not every out-of-state seller has money withheld at closing. Under South Carolina Department of Revenue guidelines, you are completely exempt from withholding if:

• You Sold at a Loss or Break-Even: If your original purchase price plus documented capital improvements and selling costs is greater than or equal to the sales price, you have zero gain and zero withholding.
• Deemed Resident Corporations: An out-of-state corporation or LLC registered with the Secretary of State that has its principal place of business in South Carolina and agrees to file a state return is exempt.
• Tax-Exempt Organizations: Charities, churches, and non-profits exempt under 26 U.S.C. § 501(a) are not subject to withholding.
• Foreclosures and Deeds in Lieu: Transfers resulting from foreclosure actions or condemnation proceedings are exempt.

Filing an Affidavit for Primary Residences

A common scenario involves a homeowner who lived in Charleston or Fort Mill for years, moved to another state for a new job two months ago, and is now closing on the sale of their old South Carolina home. Even though they live out of state on closing day, they can avoid the withholding tax if the property was their primary residence.

Under 26 U.S.C. § 121, if you owned and lived in the home as your principal residence for at least two of the last five years, you can exclude up to $250,000 of capital gain (if single) or $500,000 of capital gain (if married filing jointly) from taxation. By checking the primary residence exclusion box on your Form I-295 affidavit, no South Carolina tax will be withheld on any gain underneath those federal limits. Note that if there is a dispute over whether you were truly domiciled in South Carolina, courts look at your permanent home and intent, a standard deeply rooted in Phillips v. South Carolina Tax Commission, 195 S.C. 472 (SC Supreme Court 1940).

How 1031 Exchanges Affect SC Withholding

Real estate investors frequently use a like-kind exchange under 26 U.S.C. § 1031 to sell an investment property in South Carolina and roll the proceeds into a new investment property without paying immediate capital gains taxes. If you are conducting a 1031 exchange through a Qualified Intermediary, you can claim a full exemption from the South Carolina non-resident withholding tax on Form I-295, provided 100% of the gain is deferred.

However, be careful of two traps: First, if you take any cash out at closing (known as 'boot'), that recognized gain is immediately subject to South Carolina withholding. Second, if your 1031 exchange fails because you cannot identify a replacement property within 45 days or close within 180 days, the Qualified Intermediary is legally required to withhold the South Carolina tax before returning your funds. Any tax disputes with the Department of Revenue that cannot be resolved by audit are litigated before the South Carolina Administrative Law Court, Columbia.

Costs and Timeline for Non-Resident Tax Compliance

• Closing Attorney Preparation Fee: Most South Carolina closing attorneys include the preparation of Form I-290 and Form I-295 in their standard seller closing package (typically $0 to $150).
• CPA Tax Return Preparation: Hiring an accountant to file your South Carolina Non-Resident tax return (Form SC1040, South Carolina, Department of Revenue, Individual Income Tax Return with Schedule NR) to get your excess withholding refunded typically costs $250 to $600.
• Remittance & Refund Timeline: The closing attorney remits your withheld funds to the state by the 15th of the month following closing. If you overpaid, you can either file an amended withholding refund request using Form I-290, South Carolina, Department of Revenue, Nonresident Real Estate Withholding (with the 'Amended' box checked) prior to the end of the tax year, or wait to file your standard state income tax return between January and April of the following year, with refunds usually arriving in 4 to 8 weeks.
