How to Calculate Capital Gains Tax on Property? + FAQs

Did you know? In 2023, the typical U.S. home seller earned about $121,000 in profit on their house sale – a record high. However, that windfall can come with a hefty tax bill if you don’t plan ahead.

Capital gains tax on property is the tax you pay on the profit from selling real estate. To calculate this tax, start with your selling price and subtract your cost basis (what you paid for the property, plus certain improvements, minus any depreciation). The difference is your capital gain. Then, apply the appropriate tax rate based on how long you owned the property and your overall income level.

If you owned the property for more than one year, your profit is taxed at a favorable long-term capital gains rate (typically 0%, 15%, or 20%). Hold it for one year or less, and the gain is short-term, taxed as ordinary income at your regular tax bracket (which could be much higher). Homeowners selling a primary residence may also qualify for a big tax break (excluding up to $250,000 or $500,000 of gain), while investors and businesses face additional rules like depreciation recapture on rentals.

What Is Capital Gains Tax on Property? (Definition & Why It Matters)

Capital gains tax on property is a federal tax on the profit you earn from selling real estate (such as a house, condo, land, or rental building). In simple terms, it’s a tax on the difference between what you paid for the property and what you sold it for. This tax only kicks in when you realize a gain – meaning you actually sell or dispose of the property for a profit. (If your property’s value goes up on paper but you haven’t sold it, you don’t pay capital gains tax until you sell.)

The reason this tax matters is that it can take a significant bite out of your sale proceeds if you’re not prepared. For example, selling a second home or investment property at a large profit could trigger a tax bill in the tens of thousands of dollars. On the other hand, knowledge is power – understanding the rules can help you minimize or even avoid the tax legally. That’s why it’s crucial to know how capital gains tax works before you sell a property, so you can plan the timing and take advantage of any tax breaks.

Note: Don’t confuse capital gains tax with other taxes related to real estate. It’s not property tax (the annual tax you pay to your local government for owning property). It’s also different from transfer taxes or stamp duties (one-time taxes some states or counties charge when property changes hands). Capital gains tax is specifically the federal (and sometimes state) income tax due on your profit from the sale.

Short-Term vs. Long-Term Capital Gains: Why Timing Matters

How long you own your property directly affects the tax you’ll pay on the profit. Short-term capital gains (property held one year or less) are taxed at your ordinary income tax rates. Those rates follow the standard income tax brackets (ranging from around 10% up to 37% at the federal level). Long-term capital gains (property held for more than one year) enjoy special lower tax rates – usually 0%, 15%, or 20% – depending on your total taxable income. In other words, simply owning a property for more than 12 months can potentially cut your tax rate on the sale by half (or even more).

Why does this one-year mark matter so much? It’s because the U.S. tax code incentivizes and rewards long-term investment over short-term flips. Lawmakers want to encourage people to hold onto assets longer, so they offer a tax discount for doing so.

For example, imagine you’re in the 35% tax bracket and you flip a house after 6 months for a $50,000 profit. That $50,000 would be taxed at 35% as a short-term gain, costing you about $17,500 in federal tax.

If instead you held that property for just over a year and then sold, the profit would be a long-term gain. At a long-term tax rate of 15%, the tax on a $50,000 gain would be only $7,500. That’s a $10,000 tax savings simply by holding the asset longer! Timing your sale to cross the one-year threshold can make a dramatic difference in your after-tax profit.

Even if you’re not a high earner, timing matters. Middle-income sellers often pay 15% on long-term gains, whereas any short-term profit is taxed at your regular rate (which might be 22% or 24%, for instance). And at lower incomes, some or all of a long-term capital gain might even qualify for the 0% tax rate – meaning you could owe nothing on the sale. Bottom line: if feasible, consider holding property for over a year to leverage these lower rates. (Note: At the upper end, very high-income individuals may also owe an extra 3.8% Net Investment Income Tax on large capital gains, but the long-term rates still generally beat short-term rates for the same taxpayer.)

The Primary Residence Exclusion: A Huge Tax Break for Homeowners

One of the best tax breaks in the U.S. is the primary residence exclusion for home sales. If you sell your principal residence (the home you live in), you may be able to exclude a huge portion of the profit from taxes. Specifically, a single homeowner can exclude up to $250,000 of capital gains, and a married couple filing jointly can exclude up to $500,000 of gain on the sale of their home. This means that many home sellers owe zero capital gains tax when they sell their house, because their profit isn’t high enough to exceed those limits.

To qualify for this exclusion, you need to meet a couple of key requirements. You must have owned the home and used it as your main home for at least 2 years out of the 5 years before the sale. (Those 2 years don’t have to be one continuous stretch; you could total 24 months of residence spread over the 5-year window.) Additionally, you generally cannot have claimed this exclusion on another home sale in the previous 2 years. For married couples wanting the full $500k benefit, both spouses should meet the 2-year use test (and at least one spouse must meet the 2-year ownership test).

What if you don’t quite meet the two-year rule? In some cases, the IRS allows a partial exclusion of gain. This typically applies if you had to sell early due to unforeseen circumstances like a job relocation, a serious health issue, or other urgent need. In such situations, you might be allowed to exclude a prorated portion of the $250k/$500k based on the fraction of two years you did meet.

For example, if you lived in the house for only one year (half of the required two) before moving for a new job, you could potentially exclude about half the normal maximum – roughly $125,000 of gain if single, or $250,000 if married.

Example: Suppose you and your spouse bought a home for $300,000 and lived there for the past 10 years. You sell it for $700,000, which means you have a $400,000 gain. Thanks to the $500,000 exclusion for joint filers, that entire $400k profit is tax-free – you owe no capital gains tax on the sale. Now, if instead you sold for $900,000 (a $600,000 gain), as a married couple you could exclude $500,000 and would only owe long-term capital gains tax on the remaining $100,000 of profit.

Keep in mind a few caveats. You can have only one primary residence at any given time, so you can’t apply the $250k/$500k exclusion to multiple properties in the same period. The IRS is strict here – you truly have to live in the home for it to count as your principal residence. Additionally, if you rented out part of your home or used a portion as a home office (and claimed depreciation for it), the home sale exclusion won’t cover the gain attributable to that portion. That part of the profit is still taxable (via depreciation recapture, explained later). Still, for most homeowners, the primary residence exclusion is a powerful tool that lets them sell their homes largely tax-free.

Selling Rental or Investment Property: Taxes & Depreciation

When you sell a rental property or any real estate held for investment (such as a vacation home or land that isn’t your primary residence), the tax rules are less forgiving than for a personal home. There’s no $250k/$500k exclusion – all the profit is potentially taxable. How much you’ll owe depends on your holding period (short-term vs. long-term, as covered above) and one additional factor unique to rental real estate: depreciation.

If you’ve been renting out a property, you likely took depreciation deductions each year. Depreciation lets you write off the cost of the building over time (as if it’s slowly wearing out), which saved you money on your yearly taxes. However, each depreciation write-off also lowers your tax basis in the property (your effective purchase cost for tax purposes). When you sell, your capital gain is calculated using this reduced basis – meaning your taxable profit is higher than it would have been without depreciation.

Depreciation recapture: To account for those prior deductions, the IRS requires that part of your gain be taxed at a higher rate. The portion of your gain equal to the depreciation you’ve taken is taxed at a special 25% maximum rate (or your normal income tax rate, if it’s lower than 25%) instead of the usual capital gains rate. In effect, the IRS “recaptures” the tax breaks you received from depreciating the property. The remainder of your gain (the amount above your original purchase price, not counting depreciation) will be taxed at the regular long-term capital gains rates (0%, 15%, or 20% depending on your income).

For example, suppose you bought a rental property for $300,000 and over the years took $100,000 in depreciation (making your adjusted basis $200,000). If you later sell this property for $350,000, your total gain would be $150,000 ($100k from depreciation plus $50k from appreciation). The $100k depreciation portion is taxed at up to 25%, while the remaining $50k is taxed at the standard long-term capital gains rate (say 15%). This shows how depreciation benefits you during ownership but adds an extra tax charge when you sell.

On the bright side, if you sell an investment property at a loss, that loss is tax-deductible (unlike a personal home loss). You can use such a capital loss to offset other capital gains. If your losses exceed your gains, you can deduct up to $3,000 of the excess loss against your ordinary income each year, carrying any remaining loss forward to future years.

Deferring the tax hit: Real estate investors have some tools to delay paying capital gains tax. One popular method is the 1031 like-kind exchange. By reinvesting the proceeds from selling one property into another qualifying property, you can defer the capital gains (and depreciation recapture) taxes. The IRS lets you swap investment properties without immediate tax as long as you follow strict timelines (such as identifying a new property within 45 days and closing on the replacement within 180 days). In essence, a 1031 exchange pushes the tax bill into the future – potentially indefinitely if you keep exchanging properties.

Flippers and short-term sales: If you sell an investment property after a very short holding period, you’ll be paying short-term capital gains tax (taxed as ordinary income). And if you make a habit of flipping houses or dealing in properties frequently, the IRS could classify you as a real estate dealer. In that case, profits aren’t treated as capital gains at all, but as regular business income (taxed at ordinary rates and possibly subject to self-employment tax). The bottom line: quick flips and short-term deals generally face much higher taxes than long-term, buy-and-hold investments.

Quick Comparison of Common Scenarios:

Scenario	Tax Outcome
Selling your primary residence (main home)	If you meet the 2-out-of-5-year ownership and use test, you can exclude up to $250,000 (single) or $500,000 (married) of gain from taxes. Only any gain above those amounts is taxable (at long-term capital gains rates). Most everyday home sales end up owing no capital gains tax thanks to this exclusion.
Selling a rental or investment property (long-term hold)	No special home-sale exclusion – the entire gain is taxable. Long-term gains are taxed at 0%, 15%, or 20% depending on income level. Plus, any depreciation you claimed is recaptured and taxed up to 25%. (Tip: You can defer taxes by doing a 1031 exchange into a new property, but if you just sell for cash, expect a tax bill.)
Short-term sale (flipping a property in under 1 year)	No special rate – profit is taxed as ordinary income at your regular tax bracket. This could be as high as 37% federally (plus state tax). You get no $250k/$500k exemption for short holds, and 1031 exchanges typically won’t apply unless the property was held for investment purposes. Short-term sellers often face a much bigger tax bite on their profits.

Special Situations: Businesses, Trusts, and Estates

Business-owned property: When a property is owned by a business entity, the tax treatment can differ from personal ownership. A C-corporation (regular corporation) that sells real estate will pay corporate income tax on any gain at the corporate tax rate (currently 21%), since corporations don’t get a special lower capital gains rate. In contrast, a pass-through entity like an S-corporation, partnership, or LLC (taxed as a partnership) doesn’t pay tax itself but passes the gain through to the owners. The individual owners then report the gain on their personal returns and pay tax at their own capital gains rates. For example, if your LLC or S-corp sells an investment property, you’ll receive your share of the gain (via a K-1 form) and pay tax on it just as if you sold a property you owned directly. One caveat: C-corps can face double taxation – if a corporation pays 21% tax on a real estate gain, then distributes the after-tax profit as a dividend to its shareholders, the shareholders must pay tax on that dividend as well.

Trusts and estates (high tax rates): If a trust or estate (i.e. a deceased person’s estate) sells a property, the tax rate thresholds are much tighter than for individuals. Trusts and estates reach the highest 20% long-term capital gains tax bracket at roughly $14,000 of income. In other words, a large gain inside a trust will likely be taxed at the maximum capital gains rate (and potentially the 3.8% NIIT surtax on top). However, many trusts can distribute capital gains to their beneficiaries. If the trust allocates or pays out the sale proceeds to a beneficiary in the same tax year, that gain can be taxed on the beneficiary’s return instead. Often this is more tax-efficient, since the beneficiary may be in a lower tax bracket than the trust.

Trust types (grantor vs. non-grantor): Not all trusts are taxed the same. A grantor trust (such as a revocable living trust that you set up for yourself) is essentially ignored for income tax purposes – the grantor/owner must report any property sale on their own 1040, and it’s just like they sold it personally. By contrast, an irrevocable trust (or a trust for someone else’s benefit) is a separate taxpayer. Unless it distributes the income or gain to someone, the trust itself will owe the tax, at those compressed trust rates mentioned above.

Inherited property and step-up in basis: A major tax benefit for inherited real estate is the step-up in basis. When someone inherits property, the tax basis typically “steps up” to the property’s fair market value as of the date of the original owner’s death. This step-up effectively wipes out the appreciation that occurred during the original owner’s lifetime for tax purposes. For example, if your parent bought a house for $100,000 decades ago and at their death the house is worth $500,000, your basis as an heir might step up to $500,000. If you sell that house soon after for around $500,000, there’s essentially no capital gain – and thus no tax – on that sale.

By contrast, if that same parent gave you the house as a gift while they were alive, you would take over the original $100,000 basis. Then if you sold the house for $500,000, you’d have to report a $400,000 gain and pay the associated capital gains tax. This difference is why many people choose to hold highly appreciated property until death rather than gift it: the step-up in basis can erase the capital gains tax bill for their heirs.

Home sales after an owner’s death: A special case worth noting – if a married couple owned a home and one spouse dies, the surviving spouse can still claim the full $500,000 primary home exclusion (rather than being limited to $250,000) provided the home is sold within two years of the spouse’s death and the usual ownership/use conditions are met. This provision helps widows and widowers avoid tax on a sale that would have been tax-free if the couple were still alive and filing jointly. Outside of that scenario, once a property is held by an estate or is no longer anyone’s personal residence, the $250k/$500k home-sale exclusion doesn’t apply – but the step-up in basis often ensures there’s little or no gain to tax in those cases.

Federal vs. State Capital Gains Taxes: Know the Difference

So far we’ve focused on federal capital gains tax rules, which apply nationwide. But don’t forget about state taxes. States have their own income tax laws, and most states will tax your real estate capital gains as well. The key thing to know is that states typically treat capital gains just like other income – meaning no special lower rate for long-term gains at the state level (with a few exceptions). However, the picture varies widely from state to state:

States with no income tax: If you live (and your property is located) in a state with no personal income tax, good news – you won’t owe state capital gains tax at all. States like Florida, Texas, Nevada, and several others fall in this category. They simply don’t tax individual income, including capital gains.
Flat or standard-rate states: Many states impose income tax at a flat rate or a graduated scale and include capital gains in your taxable income. For example, Pennsylvania taxes all income (wages or gains) at a flat rate of just over 3%. New York and New Jersey tax capital gains at the same rates as ordinary income under their progressive tax systems. This means if you’re in a higher bracket, your state tax hit on a big home sale gain could be significant.
High-tax states: In states like California and Oregon, which have high top income tax rates, your capital gain can trigger state tax of 9%, 10%, or even 13% on top of your federal tax. These states don’t give a special break to long-term gains – they’re taxed in full. So a large real estate profit in California, for instance, might face federal long-term tax (up to 20% + 3.8% NIIT) plus around 13% state tax. In total, over one-third of your gain could go to taxes.
Special cases: A few states offer partial exclusions or credits for certain capital gains, or have unique rules. For example, South Carolina allows roughly 44% of long-term capital gains to be excluded from state income. Massachusetts charges a higher rate on short-term gains (treated as ordinary income) but a standard rate on long-term gains. Always check your own state’s rules (or consult a tax expert) to see if any special provisions apply.

When it comes to state taxation, you also need to consider which state gets to tax the gain. Generally, the state where the property is located has the primary right to tax the income from its sale. If you live in a different state, you’ll typically need to file a nonresident tax return for the state where the property was sold and pay any tax there. Your home state (if different) usually will give you a tax credit for the amount of tax paid to the other state, so that you don’t get taxed twice on the same income. (For this reason, selling an out-of-state property won’t normally subject you to double taxation, but the total tax you pay will be the higher of the two states’ rates.) Keep in mind, if you move from a high-tax state to a low-tax state (or vice versa) around the time of a sale, your residency status could affect which state can tax the gain – timing and residency can matter.

Finally, remember that state taxes come on top of federal capital gains tax. When planning for a sale, consider the combined impact. For instance, you might be estimating a 15% federal capital gains hit, but if your state adds, say, another 5%, then roughly 20% of your profit will go to taxes overall. In big sales, that state portion can amount to thousands (or tens of thousands) of dollars. The bottom line: always factor in both federal and state taxes when calculating the true cost of selling your property.

How to Calculate Capital Gains Tax on Property (Step-by-Step)

Calculating your capital gains tax can be broken down into a series of steps. By following these steps in order, you’ll account for all the factors we’ve discussed:

Determine your cost basis: Start with what you originally paid for the property. Add the costs of any major improvements you made (e.g. adding a room, a new roof, remodeling that increases value or extends its life). Subtract any depreciation you claimed (if it was a rental or business property). Also add certain purchasing costs or fees if not already counted in basis (like survey fees or title fees from when you bought it). The result is your adjusted cost basis.
Determine your net selling price (amount realized): Take the gross sale price and subtract any expenses of the sale. This includes things like real estate agent commissions, attorney or escrow fees, transfer taxes, and other closing costs associated with the sale. What’s left is essentially the cash (or value) you walk away with – your net amount realized from the sale.
Calculate the capital gain (or loss): Subtract your adjusted cost basis (from step 1) from the net selling price (from step 2). If the result is positive, that’s your capital gain. If it’s negative, you have a capital loss. (Remember, a loss on a personal residence isn’t deductible, but a loss on an investment property is.)
Apply any exclusions or adjustments: If this was your primary residence and you qualify for the home sale exclusion, subtract up to $250,000 (or $500,000 for joint filers) from the gain. If you qualify for a partial exclusion due to unforeseen circumstances, subtract the allowed amount. If the property was a rental/investment, make sure you’ve accounted for depreciation in your basis as noted, because that portion of gain will be taxed differently (next step).
Determine the character of the gain – short-term vs. long-term: Look at how long you owned the property. If you owned it for more than one year, the gain is long-term. If one year or less, it’s short-term. This will decide what tax rate applies. (Long-term gains get the preferential 0%/15%/20% rates; short-term gains are taxed at your ordinary income tax rate.)
Account for depreciation recapture (if applicable): If the property was depreciated (e.g. a rental), figure out how much of your gain is attributable to depreciation. This portion – up to the total depreciation taken – will be taxed at up to 25% federal rate, regardless of the long-term preferential rates. (Any gain beyond the depreciated amount still gets the normal long-term rate.)
Find your tax rate and calculate federal tax: Based on your taxable income and the character of the gain (from steps 5 and 6), determine the applicable tax rate. For long-term gains, see which tax bracket you fall into (0%, 15%, or 20%). Apply the 25% rate to the depreciation portion. Short-term gains will be taxed according to your ordinary income bracket (e.g. you might pay 22% or 35% or whatever your top marginal rate is). Multiply the taxable gain by the respective tax rate(s) to get your tentative federal capital gains tax.
Don’t forget state taxes: If your state taxes capital gains, figure out that amount as well. This could be a flat percentage of the gain or based on your state income tax bracket. For example, if you have a $100,000 gain and your state tax rate is 5%, that’s an additional $5,000 state tax due. Add this to your federal tax from step 7 to see the combined tax impact.
Report the sale on your tax return: In practice, you’ll fill out IRS Form 8949 and Schedule D (for capital gains) when filing your taxes, detailing the sale, your basis, and the gain. If it was a rental or business property, you may also need to file Form 4797 (for sales of business property) and the unrecaptured Section 1250 gain worksheet for depreciation recapture. Make sure to pay any required tax by the appropriate deadline (quarterly estimates if necessary, or by the next tax filing due date).

By following these steps, you can arrive at a clear calculation of how much capital gains tax is owed on your property sale. It may seem complex, but breaking it down ensures you don’t miss anything important.

Avoid These Common Mistakes

Even savvy property owners can slip up when it comes to capital gains taxes. Here are some frequent mistakes to steer clear of:

Assuming all home sale profit is tax-free: Many sellers mistakenly think if you sell your house, you won’t owe tax. In reality, you must meet the IRS tests (ownership, use, and timing) to claim the $250k/$500k exclusion. Selling a home you haven’t lived in long enough (or selling a second home that’s not your primary residence) could trigger a taxable gain.
Not keeping track of your basis: Failing to save records of your purchase price and improvement costs can cost you. If you can’t document those new windows, additions, or renovations, you might end up with a higher taxable gain than necessary. Always keep receipts for major home improvements so you can increase your basis and reduce your gain at tax time.
Forgetting about depreciation recapture: Real estate investors often get a surprise tax bill because they didn’t account for depreciation. If you rented out your property, the IRS assumes you took depreciation deductions – and will recapture those when you sell. Forgetting this can lead to underestimating your tax liability (since that portion of gain is taxed at up to 25%, even for long-term holdings).
Poor timing on sales: Timing is crucial. One common mistake is selling an investment property after 11 months (yielding a high-taxed short-term gain) when holding just a month longer would qualify for long-term rates. Similarly, selling your home before you’ve hit two years of residence could mean losing out on the exclusion. Plan sales strategically to maximize tax benefits (even if that means renting the property a bit longer or delaying closing to meet a key date).
Believing “reinvestment” avoids tax: Some folks think that if they take the proceeds from a sale and immediately buy another property, they won’t owe capital gains tax. This is not true for personal homes under current law – the old rollover rule no longer exists. Unless it’s a 1031 exchange for an investment property (which has strict rules), reinvesting money in a new house won’t exempt you from taxes on the sale gain.
Neglecting state and local taxes: Don’t forget that your state (and city) might want a cut of your profit too. It’s a mistake to calculate your expected tax bill using only federal rates, only to be surprised by a state tax bill later. Research your state’s policy on capital gains, and factor that in. For example, a 10% state tax can turn what you thought was a 15% total tax hit into 25% when combined with federal – a big difference.

FAQ

Q: If I buy another house after selling, do I avoid capital gains tax?
A: No. Reinvesting sale proceeds into a new home does not exempt you from capital gains tax. The only way to avoid tax on a personal home sale is by qualifying for the $250k/$500k exclusion.

Q: Do I have to pay capital gains tax if I sell my house at a loss?
A: No. If you sell your personal residence for less than you paid for it, you owe no capital gains tax (and unfortunately you cannot deduct the loss either).

Q: Is capital gains tax separate from my regular income tax?
A: Yes. Long-term capital gains have special lower tax rates distinct from ordinary income rates, though they are still reported on the same income tax return.

Q: Does living in a house for 2 years avoid capital gains tax?
A: Yes. If you own and live in a home for at least 2 of the 5 years before sale (and meet other requirements), you can exclude up to $250k ($500k if married) of the gain.

Q: Do seniors get any extra capital gains tax breaks when selling a home?
A: No. There is no extra capital gains exemption based on age. The only exclusion is the $250k/$500k primary home exclusion, which anyone can use if they meet the ownership and residency requirements.

Q: If I inherit a house, do I have to pay capital gains tax when I sell it?
A: No. In most cases, inherited property gets a step-up in cost basis to the market value at the decedent’s death, so selling it right away often results in little or no taxable gain.

Q: Can I avoid capital gains tax on my primary home by doing a 1031 exchange?
A: No. A 1031 exchange only defers tax on investment or business property sales; it cannot be used for a personal residence. Only the primary home exclusion allows you to avoid tax on a home sale.
