Short-Term vs. Long-Term Capital Gains Tax on a House Sale
2 min read · Last updated 2026-08-05 · Reviewed by Camilo Palacio, Licensed Florida Real Estate Professional (License #3280644, REALTOR®)
Sell a house you've owned for one year or less and your profit is taxed as a short-term capital gain, at the same rates as your regular income, up to 37%. Hold it more than a year and the profit becomes a long-term capital gain, taxed at 0%, 15%, or 20% depending on your income. This rule applies on top of, and separately from, any primary-residence exclusion you might also qualify for.
| Factor | Traditional Route | Cash Flow Deals |
|---|---|---|
| Timing control over the one-year mark | Listing, showings, and buyer financing can push a closing date later or earlier than planned, making it hard to control which side of the one-year line you land on | Closing date is agreed upfront, so if timing your sale around the one-year mark matters for your tax rate, you can plan around a set date |
| Speed to close | Traditional listings often take months from list to close, especially with financing contingencies | A sale can move faster once terms are agreed, which matters if a specific tax year deadline is driving your decision |
| Certainty of net proceeds for tax planning | Buyer negotiations and appraisal gaps can change your final number late in the process | The agreed price and terms hold, so the number you use to estimate your tax bill doesn't shift under you |
The One-Year Line That Changes Everything
The IRS draws a hard line at one year of ownership. Sell on day 365 or earlier and your profit counts as a short-term capital gain. Sell on day 366 or later and it's a long-term capital gain. The clock starts the day after you acquired the property and ends the day you sell it. There's no partial credit for being close. A house sold at eleven months gets taxed at ordinary income rates, full stop, even if the difference between that and thirteen months is a whole tax bracket's worth of money.
How Short-Term Gains Get Taxed
Short-term capital gains on a house are taxed exactly like your salary or business income, at your regular federal bracket, which runs as high as 37% depending on your total taxable income for the year. There's no special reduced rate. If you flip a property or sell an inherited house within a year of acquiring it, whatever profit shows up gets added to your other income and taxed at whatever bracket that combined total lands in. This is the single biggest reason quick flips are less profitable than they look on paper before taxes.
How Long-Term Gains Get Taxed
Hold the property more than a year and your profit shifts to long-term capital gains treatment, taxed at 0%, 15%, or 20% based on your taxable income for the year, with the exact income thresholds for each bracket adjusted annually for inflation. Most sellers with moderate income land in the 15% bracket. That's a meaningfully lower rate than ordinary income tax for most people, which is why timing a sale to cross the one-year mark, when it's realistic to do so, is worth a real look before you list.
This Rule Is Separate From the Primary Residence Exclusion
The short-term versus long-term rule and the primary residence exclusion under Section 121 are two different things that can both apply to the same sale. The exclusion lets a homeowner who owned and lived in the property as their main home for at least two of the last five years exclude up to $250,000 of gain from tax, $500,000 for a married couple filing jointly. That exclusion has its own two-year ownership and use test, separate from the one-year mark that decides short-term versus long-term rates. An investment property or a house you didn't live in doesn't get the exclusion at all, and the short-term or long-term rate is all that applies.
The Net Investment Income Tax Can Add On Top
Above certain income thresholds, an additional 3.8% Net Investment Income Tax can apply to capital gains, including gains from a house sale, on top of the regular capital gains rate. This tax is calculated on the smaller of your net investment income or the amount your modified adjusted gross income exceeds the threshold for your filing status. It's easy to miss if you're estimating your tax bill off the standard capital gains brackets alone, and it can meaningfully change the math on a large gain.
Common questions
How is the one-year holding period counted for a house sale?
The clock starts the day after you acquired the property and runs through the date you sell it. Own it 365 days or fewer and the gain is short-term. 366 days or more and it's long-term.
Do short-term and long-term rates apply if I qualify for the primary residence exclusion?
They can still matter. The exclusion removes up to $250,000 or $500,000 of gain from tax entirely, but any gain above that exclusion amount is still taxed at short-term or long-term rates depending on how long you owned the property.
Is there a way to reduce short-term capital gains tax on a house I've owned less than a year?
The most direct lever is time, holding until you cross the one-year mark shifts the rate down substantially. Beyond that, tracking capital improvements to raise your cost basis reduces the taxable gain regardless of holding period.
What income triggers the extra 3.8% Net Investment Income Tax?
It applies once your modified adjusted gross income passes a threshold set by filing status, and it's calculated on the smaller of your net investment income or the amount over that threshold. Check current IRS figures for your filing status before assuming it applies.
