What Is Capital Gains Tax on a Home Sale?

Capital gains tax is the tax you pay on the profit from selling an asset: in this case, your home. It’s calculated as the difference between your home’s selling price and its adjusted cost basis (usually the original purchase price plus certain improvements and expenses). Capital gains tax typically only applies if the property has appreciated in value and you’ve made a profit from the sale.

There are two types of capital gains:

• Short-term capital gains apply if you owned the home for one year or less before selling. These are taxed at your ordinary income tax rate.
• Long-term capital gains apply if you owned the home for more than one year, and are taxed at lower rates, typically 0%, 15%, or 20% depending on your income bracket at a federal level. This does not include the taxes you’ll owe in state taxes.

Examples where capital gains tax may apply:

• You sell a second home or investment property that increased in value.
• You sell your primary residence but don’t qualify for the IRS exclusion ($250,000 for individuals or $500,000 for married couples filing jointly).
• You exceed the exclusion limits of $250,000 or $500,000.
• You sell your home within a year of buying it, triggering short-term capital gains.

How the Capital Gains Exclusion Works for a Primary Residence

The IRS offers a capital gains tax exclusion for homeowners who sell their primary residence, helping many avoid paying taxes on the profit from the sale. If you meet the criteria, you can exclude up to $250,000 of capital gains if you’re single, or up to $500,000 if you’re married and filing jointly.

To qualify for this exclusion, you must meet two key requirements:

• Ownership Test: You must have owned the home for at least two years.
• Use Test: You must have lived in the home as your primary residence for at least two of the last five years before the sale.

These two years don’t need to be consecutive, and you don’t need to live in the home at the time of sale, as long as the total adds up to two years within the five-year window.

This exclusion only applies to the sale of a primary residence, not to investment properties or second homes. It also assumes the home was purchased using a traditional mortgage or other standard financing methods; unique tax situations (such as inherited homes, gifts, or 1031 exchanges) may have different rules.

For example, if you’re a married couple who bought a home with a traditional mortgage, lived there for at least two years, and then sold it for a $480,000 gain, you would likely owe no capital gains tax, since the full amount falls within the $500,000 exclusion limit.

Understanding these rules can help you time your sale strategically, and potentially save tens or even hundreds of thousands in taxes.

What Factors Impact How Much Capital Gains Tax You’ll Owe?

Several variables influence the amount of capital gains tax you may owe when selling your home. Understanding these factors can help you estimate your tax liability and explore potential ways to reduce it:

• Purchase Price vs. Sale Price: The difference between what you paid for the home and what you sold it for, also known as your capital gain, is the starting point for calculating tax. In a strong housing market, where home appreciation is significant, your gains may be much higher, increasing your potential tax bill if you don’t qualify for an exclusion.
• Length of Ownership: If you owned the home for less than one year, any gain is considered a short-term capital gain and taxed at your ordinary income rate, which is often higher. If you held the home for more than one year, you may benefit from long-term capital gains rates, which are typically lower (0%, 15%, or 20% at the federal level).
• Home Improvements: Capital improvements — such as a new roof, kitchen remodel, or room addition — can increase your cost basis, effectively reducing your taxable gain. Keeping records of major upgrades can save you significantly when it’s time to sell.
• Filing Status and Tax Bracket: Your filing status and your income tax bracket determine the long-term capital gains rate you’ll pay. At the federal level, higher-income taxpayers may fall into the 20% capital gains bracket, while those with moderate incomes might pay only 15% or even 0%.
• Net Investment Income Tax (NIIT): High earners may also be subject to the 3.8% Medicare surtax, also known as the Net Investment Income Tax. This applies if your modified adjusted gross income (MAGI) exceeds $200,000 (single) or $250,000 (married filing jointly) and could increase your effective tax rate on capital gains.

Tips to Reduce or Avoid Capital Gains Tax When Selling Your Home

While capital gains tax can take a bite out of your home sale profits, there are several strategies that may help you reduce, or even eliminate, what you owe. Here are some of the most effective tactics:

• Time your sale to meet the 2-of-5 year rule: To qualify for the IRS capital gains exclusion ($250,000 for single filers or $500,000 for married couples filing jointly), ensure you’ve owned and lived in the home for at least two of the past five years. Timing your sale carefully can mean the difference between owing taxes or paying none at all.
• Increase your basis with qualified home improvements: Keep detailed records of any major home improvements, such as kitchen remodels, new roofs, or energy-efficient upgrades. These costs increase your adjusted basis, which lowers your taxable gain when you sell. Simple repairs don’t count, but capital improvements do.
• Use tax-loss harvesting to offset gains: If you’ve sold other investments (like stocks) at a loss in the same year, you may be able to use those losses to offset your real estate capital gains. This strategy, known as tax-loss harvesting, can be a savvy way to minimize your overall tax bill.
• Convert a rental property into a primary residence: In some cases, you may be able to convert a rental property into your primary residence, live in it for at least two years, and then qualify for partial exclusion. However, the rules are complex and often affected by recent tax policy changes, so it’s wise to consult a tax professional before attempting this strategy.

Taking the time to understand these tactics and planning ahead can help you keep more of your profit when selling a home. As always, stay informed about current tax policy changes that may affect real estate transactions or exclusions in your area.
