A 1031 exchange in South Carolina lets you sell investment real estate and reinvest in like-kind property while deferring the tax on the gain. The federal rules apply the same way everywhere. South Carolina is a study in contrasts: it withholds a high percentage from nonresident sellers at closing, yet offers one of the more generous capital gains deductions in the country, and it taxes investment property at a higher rate than owner-occupied homes. We act as your qualified intermediary, holding the proceeds and handling the documentation so the exchange holds from sale to closing.

How much is capital gains tax on real estate in South Carolina?
South Carolina taxes income at a top rate of around 6% for 2026, and the rate structure is being adjusted under recent legislation, so confirm the current figure for your year. The important feature for real estate is that South Carolina allows a 44% deduction for net long-term capital gains, so the effective top rate on a long-held property gain is closer to 3.4%. That sits on top of the federal tax an exchange also defers:
- Long-term capital gains at 0%, 15%, or 20%, with the 20% rate applying above $545,500 of taxable income for single filers and $613,700 for married couples filing jointly in 2026.
- The 3.8% Net Investment Income Tax above $200,000 of modified adjusted gross income for single filers, $250,000 for married couples.
- Depreciation recapture, taxed as unrecaptured Section 1250 gain at up to 25%.
- South Carolina's tax on the gain, after the 44% long-term deduction.
South Carolina conforms to Section 1031, so a properly structured exchange defers both the federal and the South Carolina tax. The full federal framework is in our main 1031 exchange guide.
South Carolina's nonresident withholding
When a nonresident sells South Carolina real estate, the buyer withholds 7% of the amount realized from an individual, or 5% from a corporation, and reports it on Form I-290. The seller can reduce the withholding to the amount based on the actual gain by providing the South Carolina withholding affidavit. It is a prepayment against the South Carolina tax, not an extra tax, but it pulls cash at the table. In a 1031 exchange where no gain is recognized, you certify the exemption on Form I-295, supported by your intermediary's documentation, so the withholding is not collected.
A property-tax caveat for investors
South Carolina taxes owner-occupied homes very lightly, which is why the state is often described as low property tax, but investment and rental property is treated differently. Non-owner-occupied property is assessed at a higher ratio, 6% rather than the 4% applied to a primary residence, and it does not receive the owner-occupant school-operating tax relief. The practical result is that a replacement property held for investment carries a materially higher property tax bill than the headline residential figure suggests, so use the investment rate, not the owner-occupant rate, when you underwrite a South Carolina deal.
South Carolina 1031 exchange rules and timeline
The federal deadlines govern, and they are strict:
- 45-day identification. Identify replacement property in writing within 45 days of the sale.
- 180-day closing. Close within 180 days of the sale, or by your return due date including extensions, whichever is earlier.
- No constructive receipt. Proceeds go to your qualified intermediary, never to you.
- Equal or greater value and debt. Reinvest all net proceeds and match or exceed the relinquished value and debt, or the shortfall is taxable boot.
- Same taxpayer. The entity that sold must be the entity that buys.
1031 exchanges across South Carolina markets
Charleston anchors the state's coastal exchange activity, with a fast-growing port driving industrial and logistics demand, alongside strong tourism, multifamily, and a regional automotive and aerospace base. The Upstate, around Greenville and Spartanburg, is a major manufacturing corridor along I-85, home to large automotive and tire plants, and a frequent target for industrial exchanges. Columbia, the capital and university city, adds multifamily and commercial demand, and the coast around Myrtle Beach and Hilton Head carries resort, short-term rental, and second-home property. Remember the higher investment-property assessment ratio when comparing any of these markets.
Common South Carolina 1031 exchange mistakes
- Not certifying the exchange on Form I-295, so 7% is withheld on the full amount realized under I-290 and tied up.
- Underwriting a replacement property at the owner-occupant property tax rate rather than the higher investment rate.
- Overlooking the 44% long-term capital gains deduction when modeling the state tax.
- Taking receipt of the proceeds, or missing the 45-day identification window.
Start your South Carolina 1031 exchange
Set up your exchange before your relinquished property closes, so the I-295 certification is in place and the proceeds never reach your hands. Contact our team to begin, or to talk through a specific deal.
Frequently asked questions
How much is capital gains tax on real estate in South Carolina?
South Carolina taxes income at around 6% for 2026, but a 44% deduction for net long-term capital gains brings the effective top rate on a long-held property gain to roughly 3.4%, on top of federal capital gains tax.
Is there nonresident withholding when I sell South Carolina property?
Yes. The buyer withholds 7% of the amount realized from an individual or 5% from a corporation on Form I-290. In a 1031 you certify the exemption on Form I-295.
Why is my South Carolina investment property tax higher than expected?
Investment and rental property is assessed at a 6% ratio rather than the 4% for an owner-occupied home and does not get the owner-occupant school-tax relief, so the bill is higher than the headline residential rate.
Do I need a qualified intermediary for a South Carolina 1031 exchange?
Yes. The intermediary must hold the proceeds and facilitate the exchange, and supports the I-295 certification. Engage one before the relinquished property closes.
