What to Know About Capital Gains Taxes When Selling a Home in South Carolina

Selling a home is an exciting milestone, but it also comes with tax implications that many homeowners overlook. Understanding capital gains taxes is essential, especially in South Carolina. If you’ve never sold a home before, this guide explains everything—from the federal exclusions to SC state rules—so you can plan your sale wisely and keep as much of your profit as possible.

What is Capital Gains Tax?

Capital gains tax is a tax on the profit you make when selling an asset, like a house. For example, if you purchased your home for $200,000 and sell it for $300,000, the $100,000 profit could be subject to taxation.

There are two types of capital gains:

1. Short-term capital gains – Applies if you owned the home for less than one year. Taxed at your ordinary federal income rate.
2. Long-term capital gains – Applies if you owned the home for more than one year. Rates are typically 0%, 15%, or 20% federally, depending on income.

Most homeowners qualify for long-term treatment, as homes are usually owned for multiple years.

Federal Capital Gains Tax and the Primary Residence Exclusion

The IRS provides a generous primary residence exclusion:

• Single taxpayers: Exclude up to $250,000 in gains
• Married filing jointly: Exclude up to $500,000 in gains
• Requirements:
• Ownership of the home for at least 2 years
• Lived in the home as your primary residence for at least 2 of the last 5 years
• Not claimed the exclusion for another home in the past 2 years

Example:

• Home bought for $250,000
• Sold for $700,000 after 3 years
• Gain: $450,000
• Married couple can exclude $500,000 → no federal tax owed

Calculating Your Adjusted Cost Basis

Your adjusted cost basis determines taxable gain:

Adjusted basis = Purchase price + Capital improvements – Depreciation (if applicable)

Examples of Capital Improvements:

• Kitchen/bathroom remodels
• New HVAC system
• Adding a deck, garage, or finished basement

Routine repairs like painting do NOT count.

Example:

• Purchase price: $250,000
• Improvements: $50,000
• Sale price: $400,000

Adjusted gain = $400,000 – ($250,000 + $50,000) = $100,000

If single, $100,000 < $250,000 exclusion → no tax owed.

South Carolina Capital Gains Tax

South Carolina taxes capital gains as ordinary income:

• SC income tax rates: 0%–7%, depending on taxable income
• Net capital gain is added to other income
• Fully excluded federal gains are usually not taxed in SC

Example:

• Married couple sells home, gain: $400,000
• Fully excluded under federal primary residence rules → SC does not tax it

If exclusion doesn’t apply (second home, rental, inherited property), SC will tax gains at your marginal rate.

Special Considerations for South Carolina Homeowners

1. Selling an Investment Property

If your property is not your primary residence, federal exclusion doesn’t apply. Gains may be taxable both federally and in SC. Proper planning is crucial.

2. Understanding Your Property Type

The type of property—primary residence, second home, or investment property—affects capital gains tax eligibility. Only primary residences qualify for the federal exclusion; second homes and investment properties do not.

3. Selling a Home Due to Divorce or Life Changes

Divorce can complicate home sales, especially regarding joint ownership and the federal exclusion.
