One of the most common worries when selling a home is a surprise tax bill on the profit. The good news: most people who sell their primary residence owe no federal capital gains tax at all, thanks to a generous exclusion. Here is how it works, when tax does apply, and what to keep in mind in South Carolina.
The federal home-sale exclusion (Section 121)
Under federal law, when you sell your main home you can exclude a large chunk of the profit from capital gains tax:
- Up to $250,000 of gain if you file single.
- Up to $500,000 of gain if you are married filing jointly.
To qualify, you generally must have owned and used the home as your primary residence for at least 2 of the 5 years before the sale (the two years don’t have to be consecutive). You also generally can’t have used the exclusion on another home sale within the prior two years. Because these limits are large, the majority of Upstate homeowners selling their main home owe no federal capital gains tax.
When capital gains tax can apply
You may owe tax when:
- Your gain exceeds the $250,000 / $500,000 exclusion (more common with long-held or high-appreciation homes).
- The property was not your primary residence - a second home, a rental, or a vacant lot, which don’t get the exclusion. (For an investment property sold at a loss, different and often favorable rules apply - see selling a rental at a loss.)
- You didn’t meet the 2-of-5-year ownership and use test, though a partial exclusion may apply for certain moves (job, health, unforeseen circumstances).
“Gain” is not the full sale price - it is the sale price minus your cost basis (what you paid, plus qualifying improvements, plus selling costs). Good records of improvements can meaningfully reduce a taxable gain.
Don’t forget South Carolina state tax
The federal exclusion is only part of the picture. South Carolina taxes capital gains as part of your state income, so a gain that is taxable federally can also carry state tax (South Carolina does provide a partial deduction on certain long-term gains). If your sale might exceed the exclusion, a CPA can estimate both the federal and state effect.
Inherited homes get a big break
If you inherited the home, it usually receives a “stepped-up basis” - its value is generally reset to the date-of-death value - which often means little or no taxable gain if you sell soon after. We cover this in selling an inherited house.
