Many South Carolina homeowners can sell their main home without paying capital gains tax on some or all of their profit. If part of your gain is taxable, eligible expenses and South Carolina’s long-term capital gains deduction may help reduce your bill.
Whether you own a home in Greenville, Greer, Simpsonville, or Travelers Rest, planning before your house sale can help you avoid surprises.

Do I Have to Pay Capital Gains Tax When I Sell My South Carolina Home?
Not always. Qualifying homeowners can generally exclude up to:
- $250,000 of gain for an individual taxpayer.
- $500,000 of gain for a married couple filing jointly who meet the requirements.
These limits apply to your profit, not your home’s selling price.
Generally, you must have owned the home and lived in it as your main residence for at least two of the five years before closing. You also generally cannot have used the exclusion on another home sold during the previous two years.
For the full $500,000 joint exclusion, at least one spouse must meet the ownership requirement, both must meet the residence requirement, and neither can have used the exclusion within the previous two years.
South Carolina generally recognizes the federal principal-residence exclusion. A qualifying gain excluded federally is generally excluded from South Carolina income tax as well. Rental or business use requires additional review.
What Is the Capital Gains Tax Rate in South Carolina for 2026?
There are two parts to consider: federal taxes and South Carolina taxes.
Federal capital gains tax
For property held more than one year, most taxable long-term gains are taxed at 0%, 15%, or 20%, depending on your total taxable income.
For single filers in 2026:
- 0%: Taxable income up to $49,450.
- 15%: Taxable income over $49,450 through $545,500.
- 20%: Taxable income over $545,500.
For married couples filing jointly:
- 0%: Taxable income up to $98,900.
- 15%: Taxable income over $98,900 through $613,700.
- 20%: Taxable income over $613,700.
Your taxable gain is included when determining these brackets. Different portions of a gain can be taxed at different rates.
Property held one year or less generally produces short-term gain taxed at ordinary federal income tax rates. Higher-income sellers may also owe the 3.8% Net Investment Income Tax on some taxable gain. Depreciation-related gain can have separate tax treatment.
South Carolina capital gains tax
South Carolina changed its individual income tax system for 2026. State tax is calculated using:
- 1.99% for South Carolina taxable income below $30,000.
- 5.21% of South Carolina taxable income, minus $966, for taxable income of $30,000 or more.
These rules apply to 2026 income, reported on returns generally due in 2027. Older articles using a 6% or 7% top rate do not reflect the current 2026 rules.
South Carolina’s 44% capital gains deduction
South Carolina allows individuals to deduct 44% of qualifying net long-term capital gain recognized by the state.
In simple terms, 56% of an eligible gain remains in the state income calculation before other applicable deductions and adjustments.
This is a deduction from taxable income—not a 44% discount on your tax bill. Short-term gains do not qualify. Capital losses and the character of your gain can affect the calculation.
How Much Capital Gains Tax Will I Pay on $300,000?
First, decide whether $300,000 means your selling price or your gain. A home selling for $300,000 does not automatically create $300,000 of taxable income.
The examples below assume $300,000 is your gain after eligible selling expenses and basis adjustments.
Single homeowner who qualifies for the full exclusion
You could exclude $250,000, leaving $50,000 potentially taxable for federal purposes.
If the entire $50,000 falls into the 15% federal capital gains bracket, the federal tax would be:
$50,000 × 15% = $7,500
If that remaining gain also qualifies for South Carolina’s 44% deduction:
- State capital gains deduction: $22,000.
- Gain remaining in the state income calculation: $28,000.
Your state tax then depends on your other income and deductions.
Married couple who qualify for the full exclusion
A married couple filing jointly who meet all requirements could exclude the entire $300,000 gain from federal income tax.
That qualifying excluded gain would generally also be excluded from South Carolina income tax.
Investment property with no exclusion or deferral
If all $300,000 is qualifying net long-term capital gain, South Carolina’s 44% deduction would remove $132,000, leaving $168,000 in the state income calculation.
Federal tax would be calculated separately.
These examples are illustrations, not complete tax estimates. Depreciation, capital losses, additional taxes, and income-based deductions can change the result. South Carolina’s new 2026 deduction system also means a large taxable gain can affect other deductions.
What Expenses Can Reduce Capital Gains on a Home Sale?
Your gain is generally calculated as:
Selling price − eligible selling expenses − adjusted basis = gain
Your adjusted basis usually starts with your purchase price. Eligible purchase costs and improvements can increase it, while depreciation and certain other adjustments can reduce it.
Eligible selling expenses
Costs directly related to your sale may reduce your gain, including:
- Real estate commissions.
- Advertising expenses.
- Certain legal and settlement fees.
- Qualifying transfer or deed-recording charges you pay.
Have your accountant review the closing statement rather than deducting an estimated percentage of the selling price.
Improvements and purchase costs
Certain title, recording, and legal fees from your purchase can become part of your basis.
Qualifying improvements may also increase it, such as:
- A new roof.
- A home addition.
- A kitchen renovation.
- A new heating and cooling system.
Routine maintenance generally does not increase basis. Your own unpaid labor does not count, and previously deducted expenses or tax credits may require adjustments.
A Greenville home-sale example
Suppose you:
- Bought your home for $320,000.
- Made $40,000 in qualifying improvements.
- Sold it for $500,000.
- Paid $30,000 in eligible selling expenses.
Your simplified gain would be:
$500,000 − $30,000 − $360,000 = $110,000
A homeowner who meets the full exclusion requirements could potentially exclude that entire gain.
Your mortgage payoff does not reduce your taxable gain. It affects the cash you receive at closing, but it is separate from this calculation.
How Can I Legally Avoid Capital Gains Taxes on Real Estate Sales?
Some strategies eliminate qualifying taxable gain. Others reduce or postpone tax.
1. Check your eligibility before choosing a closing date
If you are close to meeting the two-year ownership or residence requirement, your closing date could make a significant difference.
You may qualify for a partial federal exclusion if you sell sooner because of certain work, health, or unforeseen circumstances. Ask your accountant to review your dates before accepting an offer.
2. Understand the rules before turning your home into a rental
There is no automatic two-year tax-free rental period.
If you owned and lived in the home continuously for at least two years immediately before moving out, selling before the third anniversary of your move-out date generally preserves the federal two-out-of-five-year residence requirement. Other requirements still apply.
Gain attributable to depreciation allowed or allowable during rental use after May 6, 1997 generally cannot be excluded—even if you never claimed the deductions.
Renting a property before making it your main home can also limit the exclusion.
For Greenville County homeowners, rental conversion can also affect the property’s eligibility for the 4% owner-occupied legal-residence assessment. That is a separate property-tax issue to include when comparing selling with renting. Check with the county assessor before making the change.
3. Use the state’s long-term capital gains deduction when eligible
If some gain remains taxable, make sure your accountant evaluates South Carolina’s 44% deduction.
Holding a property for more than one year can matter, but it does not guarantee every part of the gain qualifies. Rental-property depreciation and properties held for sale in a flipping business require separate analysis.
4. Consider a 1031 exchange for investment property
A 1031 exchange can postpone tax when you exchange qualifying investment or business real estate for other qualifying real estate. South Carolina recognizes qualifying federal Section 1031 exchanges.
For a typical deferred exchange, you must:
- Arrange the exchange before closing, usually through a qualified intermediary.
- Identify replacement property in writing within 45 days after transferring the property you are selling.
- Receive replacement property within 180 days, or your federal tax-return due date including extensions, whichever comes first.
- Follow rules that prevent you from receiving or controlling the sale proceeds.
Cash, certain debt relief, or other nonqualifying property received can make part of the gain taxable.
A 1031 exchange generally does not apply to your personal home, and it postpones tax rather than automatically eliminating it.
5. Keep records and review your timing
Save your purchase closing statement, improvement receipts, and sale closing statement. These records help prevent you from overstating your gain.
If some gain will be taxable, ask whether selling in a lower-income year could help. Remember that buying another personal home does not automatically eliminate capital gains tax on your sale.
