South Carolina Real Estate Capital Gains Tax

If you’re selling a house, rental, or land in South Carolina, the tax bill on your profit is probably the biggest unknown in the deal. South Carolina taxes your gain as regular income but knocks a large chunk off the top before it’s taxed.

Between a new state income tax structure, inflation-adjusted federal brackets, and special withholding rules for out-of-state sellers, most sellers pay far less than they expect once the deductions apply correctly.

Key Takeaways

• South Carolina lets individuals deduct 44% of net long-term capital gain before state tax applies.
• The state’s income tax structure changed for 2026, cutting the top rate sellers pay on the taxable portion of a gain.
• Federal long-term capital gains rates stay at 0%, 15%, or 20% depending on your income.
• Selling your primary residence can wipe out up to $250,000 (or $500,000 for married couples) of gain entirely.
• Nonresident sellers face mandatory withholding at closing, though it can often be reduced.

How Does South Carolina Tax Capital Gains on Real Estate Sales?

South Carolina doesn’t have a separate capital gains tax.

Your gain flows into regular state taxable income and gets taxed at your ordinary rate, but the state carves out a large deduction first. A South Carolina real estate capital gains tax attorney can walk you through how your specific sale is treated, since rental property, land, and a primary home don’t all follow the same rules.

What Is South Carolina’s 44% Capital Gains Deduction?

Individuals, estates, and trusts may deduct 44% of net capital gain recognized in South Carolina during a taxable year under SC Code Section 12-6-1150. This deduction applies only to long-term gains. Here’s what qualifies:

• The property must have been held for more than one year.
• Net capital gain is defined the same way as in Internal Revenue Code Section 1222 and related sections.
• Short-term gains, from property flipped within a year, don’t get any deduction and are taxed in full. On a $200,000 long-term gain, only $112,000 actually shows up on your South Carolina return before your rate applies.

How Much Will You Owe in Federal Capital Gains Tax in 2026?

Federal treatment depends on how long you owned the property. For 2026, federal long-term capital gains are taxed at 0%, 15%, or 20% depending on taxable income: single filers pay 0% up to $49,450, 15% up to $545,500, and 20% above that; married filing jointly thresholds are $98,900 and $613,700.

Short-term gains skip this favorable treatment. Gains on assets held one year or less are added to your other income and taxed at your ordinary marginal rate, up to 37% in 2026. High earners should also watch the net investment income tax, a separate 3.8% surtax that stacks on top of the capital gains rate above certain income levels.

Can You Avoid Capital Gains Tax by Selling Your Primary Residence?

Often, yes, and this is the exclusion most Fort Mill homeowners never fully use. If you have a capital gain from the sale of your main home, you may qualify to exclude up to $250,000 of that gain from your income, or up to $500,000 if you file a joint return with your spouse.

To qualify, you must have owned and used the home as your main home for at least two of the five years prior to the sale, per the federal home sale exclusion rules. A couple who bought a house in York County a decade ago and sold it for a $400,000 profit could owe nothing at all, federally or to the state, if they meet the ownership and use tests.

What If You’re a Nonresident Selling South Carolina Property?

Out-of-state owners face an extra step at closing: South Carolina requires the buyer to withhold a percentage of the gain when the seller lives outside the state.

• Individual nonresident sellers face 7% withholding on the gain.
• Corporate nonresident sellers face 5% withholding.
• The buyer remits the withheld amount using Form I-290 by the 15th day of the month after the sale.

A seller can often reduce this by filing an affidavit showing the actual gain instead of the full sale price, which can shrink what’s held back significantly.

South Carolina’s 2026 Tax Overhaul Changes the Math for Sellers

Most guides to this topic still quote 2025 or 2021 rates. On March 30, 2026, Governor Henry McMaster signed H. 4216 into law, modifying South Carolina’s individual income tax rates so income under $30,000 is taxed at 1.99% and income at $30,000 and above is taxed at 5.21%, minus $966.

That change lowers the effective state rate on the taxable 56% of a long-term real estate gain compared to the 6% top rate that applied just one year earlier under the 2026 tax reform law.

How Can a 1031 Exchange Help You Defer the Tax?

If the property was an investment, not your home, a like-kind exchange lets you roll the gain into a new property and push the tax bill down the road. The IRS rules for a 1031 like-kind exchange require strict timelines, including identifying a replacement property within 45 days of closing.

This strategy works well for landlords selling a rental near Fort Mill who plan to reinvest rather than cash out. A South Carolina real estate capital gains tax attorney can help structure the exchange correctly, since a missed deadline turns the deferral into a fully taxable sale.

Frequently Asked Questions

Do I have to pay South Carolina capital gains tax if I sell my home?

Not necessarily. If you meet the ownership and use tests, the federal exclusion of up to $250,000 (or $500,000 married) applies to South Carolina too, since the state starts with your federal taxable income. Any gain above that limit is still subject to the 44% deduction before state tax applies.

How is capital gains tax calculated on inherited property in South Carolina?

Inherited property generally gets a stepped-up basis to the fair market value on the date of death, which often erases most or all of the taxable gain if you sell soon after. Talk to an attorney before listing an inherited property to confirm your basis is documented correctly.

What is the nonresident withholding tax rate on South Carolina real estate sales?

It’s 7% of the gain for individual sellers and 5% for corporations, withheld by the buyer at closing. You can request a refund of any overpayment by filing Form I-290 as amended or by claiming credit on your South Carolina income tax return.

Can I avoid capital gains tax with a 1031 exchange in South Carolina?

You can defer it, not avoid it permanently, by reinvesting the proceeds into another qualifying investment property under IRS like-kind exchange rules. The tax comes due eventually unless you keep exchanging or hold the final property until death for a stepped-up basis.

Does South Carolina tax capital gains the same as ordinary income?

Mostly, yes, since capital gains flow into your regular South Carolina taxable income and get taxed at the state’s income tax rate. The difference is the 44% deduction available for gains on property held more than a year, which ordinary wage income never gets.
