Section 1231 Losses: When Rental and Business Property Losses Are Ordinary
One of the most favorable features of Section 1231 is its treatment of losses from qualifying rental property and business property.
When Section 1231 losses exceed Section 1231 gains for the taxable year, the resulting net Section 1231 loss generally has ordinary character rather than capital loss character.
That distinction can be valuable because an ordinary loss is not subject merely because of its Section 1231 character to the annual capital loss deduction limit that applies when an individual's capital losses exceed capital gains.
Ordinary character, however, does not mean that every Section 1231 loss is automatically and fully deductible in the current year. Basis limitations, the at risk rules, passive activity limitations, and the excess business loss rules can still restrict the amount that reaches the current tax return.
A deductible net Section 1231 loss can also affect future years. If the taxpayer later has net Section 1231 gain during the next five taxable years, the prior loss can cause some or all of that future gain to be treated as ordinary income under the Section 1231 five year lookback rule.

Key Tax Takeaways
- Section 1231 generally applies to qualifying real property and depreciable property used in a trade or business and held for more than one year.
- Rental property held for the production of rents is generally treated as property used in a trade or business for purposes of Section 1231.
- Section 1231 gains and losses are combined for the taxable year.
- If the losses exceed the gains, the resulting net Section 1231 loss generally has ordinary character.
- A net Section 1231 loss is not converted into a capital loss merely because the underlying property is a long term asset.
- Ordinary character does not guarantee an unlimited current deduction.
- Basis, at risk, passive activity, and excess business loss limitations can still apply.
- Depreciation recapture is generally a gain rule, but a transaction involving several separately classified assets can contain both recapture gain and Section 1231 loss.
- Casualty and theft transactions have special preliminary netting rules before the normal Section 1231 calculation.
- A deductible net Section 1231 loss can cause future net Section 1231 gain to become ordinary income during the five year lookback period.
What Is a Section 1231 Loss?
Section 1231 applies to specified gains and losses involving property used in a trade or business and certain involuntary conversions.
For real estate and business owners, the most common Section 1231 property includes real property or depreciable property used in a trade or business and held for more than one year.
IRS Publication 544 states that property held for the production of rents or royalties is generally considered property used in a trade or business for purposes of Section 1231.
A loss generally arises when the amount realized on the disposition is less than the property's adjusted tax basis after taking into account depreciation and other applicable basis adjustments.
Example: Loss on Rental Property
Assume an investor owns qualifying rental property with an adjusted tax basis of $600,000.
After taking selling expenses into account, the investor's amount realized on the property is $500,000.
The transaction therefore produces a $100,000 loss before considering any other assets included in the sale and before the investor's other Section 1231 transactions for the year are combined.
If the property qualifies under Section 1231 and the taxpayer ultimately has an overall net Section 1231 loss for the year, that net loss generally has ordinary character.
Is a Section 1231 Loss an Ordinary Loss or a Capital Loss?
A net Section 1231 loss is generally an ordinary loss.
Section 1231 requires the taxpayer to combine qualifying Section 1231 gains and losses for the taxable year.
If the Section 1231 losses exceed the Section 1231 gains, Section 1231(a)(2) generally prevents those gains and losses from being treated as gains and losses from sales or exchanges of capital assets.
The resulting net Section 1231 loss therefore receives ordinary rather than capital treatment.
Ordinary Character Does Not Mean Unlimited Current Deduction
The statement that a net Section 1231 loss is an ordinary loss describes the character of the loss.
It does not override separate provisions that can limit whether the loss is currently deductible.
Depending on the taxpayer and activity, basis limitations, Section 465 at risk rules, Section 469 passive activity limitations, and Section 461 excess business loss rules can apply before the full economic loss produces a current tax deduction.
Why Is Ordinary Loss Treatment Generally More Favorable?
Individuals generally face a limitation when capital losses exceed capital gains. The net capital loss deduction against ordinary income is limited under Section 1211, with unused capital losses generally carried forward.
A net Section 1231 loss does not become subject to that limitation merely because the taxpayer owned the underlying property for more than one year.
This can make Section 1231 particularly favorable: qualifying net gains can potentially receive long term capital gain character, while qualifying net losses generally receive ordinary loss character.
The rules are designed so that this benefit is not unlimited. The five year lookback rule can convert later Section 1231 gain into ordinary income after the taxpayer has previously received an ordinary Section 1231 loss.
Does a Section 1231 Loss Offset Wages or Other Ordinary Income?
A deductible net Section 1231 loss has ordinary character and can therefore reduce taxable income without being subject to the capital loss limitation solely because of its character.
Whether the loss actually reduces wages or other nonpassive income in the current year depends on the other limitations that apply to the taxpayer.
For example, a Section 1231 loss arising from a passive rental activity can be limited by Section 469 even though the ultimate character of an allowed net Section 1231 loss is ordinary.
Example: Ordinary Character Versus Current Deductibility
Assume an investor has a $90,000 net Section 1231 loss from a rental activity.
The $90,000 net Section 1231 loss has ordinary character.
If the rental activity is passive to the taxpayer and the loss is limited under Section 469, however, some or all of the loss may be suspended rather than currently reducing nonpassive income.
The ordinary character of the Section 1231 loss and the passive activity limitation answer two different tax questions.
How Are Section 1231 Gains and Losses Netted?
Section 1231 treatment is based on the taxpayer's overall annual result rather than the result from only one asset.
Applicable Section 1231 gains and losses from qualifying transactions are combined for the taxable year after any required depreciation recapture and other preliminary rules have been applied.
Example: Multiple Property Transactions
Assume a taxpayer has the following qualifying Section 1231 results during the year:
| Transaction | Section 1231 Result |
|---|---|
| Rental Property A | $40,000 gain |
| Rental Property B | $130,000 loss |
The annual calculation produces a $90,000 net Section 1231 loss.
The $90,000 generally has ordinary loss character.
It is not treated as a $90,000 capital loss merely because both properties were held for more than one year.
What Happens if There Are Section 1231 Gains and Losses From Several Businesses?
The annual Section 1231 calculation is generally performed at the taxpayer level.
An individual can therefore have Section 1231 amounts from:
- Personally owned rental property
- A Schedule C business
- Partnership Schedule K1 amounts
- S corporation Schedule K1 amounts
- Other qualifying business property dispositions
Applicable allowed amounts from these different sources enter the taxpayer's Form 4797 calculation.
Example: Losses and Gains From Different Activities
Assume an individual has:
- $80,000 Section 1231 loss from personally owned rental property
- $25,000 Section 1231 gain from a partnership
- $10,000 Section 1231 loss from business equipment
Assuming all of the losses are currently allowable and no other Section 1231 items apply, the taxpayer has a $65,000 net Section 1231 loss.
That annual net loss generally receives ordinary loss treatment.
Does Depreciation Recapture Apply When Property Is Sold at a Loss?
Depreciation recapture under Sections 1245 and 1250 generally applies when depreciable property is disposed of at a gain.
If one separately identified depreciable asset is sold for less than its adjusted basis, there is no gain on that particular asset to recharacterize as ordinary depreciation recapture.
The loss can instead enter the applicable Section 1231 calculation when the statutory requirements are satisfied.
An Overall Property Loss Does Not Prove That Every Asset Was Sold at a Loss
Real estate can contain several separate federal tax assets.
A transaction involving land, a building, furniture, equipment, and cost segregation components must be analyzed asset by asset.
One Section 1245 component can be sold at a gain and generate ordinary depreciation recapture even though the combined transaction produces a larger overall Section 1231 loss from other assets.
Example: Recapture and Loss in the Same Property Sale
Assume a rental property sale includes Section 1245 equipment and a Section 1250 building.
The equipment produces a $20,000 gain that is ordinary income under Section 1245.
The building produces a $100,000 qualifying Section 1231 loss.
The Section 1245 gain is determined under the recapture rules before the remaining qualifying Section 1231 amounts are netted.
The presence of an overall economic loss therefore does not allow the taxpayer to ignore the classification and disposition result of each separate tax asset.
For a detailed discussion of these rules, see Depreciation Recapture on Rental Property .
How Do Passive Activity Rules Affect a Rental Property Section 1231 Loss?
Section 469 can limit losses arising from a passive activity.
Rental activities are generally passive unless an exception applies. For rental real estate, qualifying as a real estate professional is not enough by itself. The taxpayer must also materially participate in the applicable rental activity for it to be nonpassive.
IRS Publication 925 specifically identifies Section 1231 losses as items that may need to be accounted for separately when applying the passive activity rules.
A Section 1231 loss from passive rental property can therefore be limited or suspended even though the loss would otherwise have ordinary character under Section 1231.
Section 1231 Character and Section 469 Deductibility Are Separate
First determine the proper gain or loss character under the property disposition rules. Separately determine whether Section 469 permits the taxpayer to deduct the loss in the current year.
For more information, see Suspended Passive Rental Losses: Four Ways Real Estate Investors Can Use Them .
Can Selling the Entire Passive Activity Release the Section 1231 Loss?
Section 469(g) provides a special rule when a taxpayer disposes of the taxpayer's entire interest in a passive activity to an unrelated person in a fully taxable transaction.
When the requirements are satisfied, suspended passive losses associated with the activity can generally become deductible under the disposition rules.
This can be particularly important when a rental property sale itself produces a Section 1231 loss and the activity also has passive losses suspended from prior years.
The complete disposition rule has its own requirements and should not be assumed to apply to every property sale, especially when the activity is held through a partnership or when the taxpayer retains part of the activity.
How Do Basis Limitations Affect a Section 1231 Loss?
A taxpayer must have sufficient tax basis when an applicable basis limitation governs the loss.
This is particularly important for pass through investments.
A partner's share of partnership loss can be limited by Section 704(d) to the partner's adjusted outside basis in the partnership interest.
An S corporation shareholder's losses can be limited under Section 1366(d) by available stock basis and qualifying debt basis.
These owner level limitations can prevent part of a K1 Section 1231 loss from becoming currently deductible even though the entity correctly reported the entire allocated loss on Schedule K1.
For a detailed K1 discussion, see Section 1231 Gain on Schedule K1: Tax Rules for Real Estate and Business Investors .
How Do the At Risk Rules Affect a Section 1231 Loss?
Section 465 can further limit losses to the amount the taxpayer has at risk in the applicable activity.
The at risk amount is not always the same as tax basis.
The rules generally consider amounts of money and adjusted basis of property contributed to an activity, qualifying amounts borrowed for which the taxpayer is economically at risk, and specific statutory rules governing certain financing.
Qualified nonrecourse financing can receive special treatment for certain activities involving the holding of real property.
IRS guidance requires the at risk rules to be applied before the passive activity loss rules.
What Is the General Ordering of the Loss Limitations?
For an individual investor, the major limitations generally need to be considered in the following order when they apply:
- Applicable tax basis limitations
- Section 465 at risk limitations
- Section 469 passive activity limitations
- Section 461 excess business loss limitation
The exact basis rule depends on how the activity is owned. A partnership investment and an S corporation investment do not use the same basis limitation.
A Large Economic Loss Can Pass Through Several Tax Filters
A taxpayer can economically lose $500,000 on a business or rental investment without necessarily receiving a $500,000 current deduction.
The Section 1231 rules determine character. Other provisions can determine how much of the loss is currently allowed.
How Does the Excess Business Loss Limitation Affect Section 1231 Losses?
Section 461(l) can impose another limitation after other applicable loss restrictions have been considered.
The rule applies to noncorporate taxpayers and limits excess business losses above an annually adjusted threshold.
Current IRS Form 461 instructions provide that taxpayers generally apply the at risk rules first, then the passive activity rules, and then the excess business loss limitation.
A disallowed excess business loss is not permanently lost. Under the current statutory framework, the disallowed amount is treated as a net operating loss carryover for subsequent taxable years, subject to the applicable net operating loss rules.
Ordinary Loss Can Still Be Deferred
Section 461(l) is another example of why ordinary character and immediate deductibility are not the same thing.
A loss can be ordinary under Section 1231 but still be deferred in whole or in part by the excess business loss limitation.
How Are Casualty and Theft Losses Treated Under Section 1231?
Casualty and theft transactions involving qualifying business, rental, or investment property have a special preliminary netting rule.
Section 1231 and the Form 4797 instructions provide that if recognized casualty and theft losses exceed recognized casualty and theft gains, those casualty and theft gains and losses are not included in the normal Section 1231 netting calculation.
Instead, casualty and theft transactions are reported under the applicable Form 4684 rules.
If the recognized casualty and theft gains exceed the recognized casualty and theft losses, the applicable net amounts can enter the Section 1231 framework.
Do Not Combine Casualty Losses With Ordinary Property Sales Too Early
The special casualty and theft netting calculation must be performed before those items are included in the broader Section 1231 computation.
How Do Condemnations and Other Involuntary Conversions Fit Into Section 1231?
Section 1231 can also apply to qualifying involuntary conversions of business property and certain property held for investment when the statutory holding period and other requirements are satisfied.
Condemnations, requisitions, and other involuntary conversions can therefore generate Section 1231 gain or loss even though the taxpayer did not voluntarily sell the property.
Section 1033 can separately defer recognition of gain in qualifying involuntary conversion transactions when the replacement requirements are satisfied.
The recognition rule under Section 1033 and the character rules under Section 1231 should be analyzed separately.
What Is Not a Section 1231 Loss?
Not every loss involving real estate or a long term asset qualifies for Section 1231 treatment.
Examples that require different analysis include:
- Losses on property held for personal use
- Losses on capital assets held strictly for investment rather than qualifying Section 1231 property
- Property held primarily for sale to customers in the ordinary course of business
- Qualifying business property held for one year or less
- Losses that are not recognized under an applicable nonrecognition provision
Personal Residence Loss
A loss on the sale of a personal residence is generally not deductible merely because the home is real property.
Investment Land
Land held solely for investment generally does not become Section 1231 property merely because the taxpayer held it for more than one year. A sale can instead produce capital gain or loss.
Dealer Property
Real estate held primarily for sale to customers in the ordinary course of the taxpayer's business is generally excluded from Section 1231 treatment.
This distinction can be important for developers, builders, subdividers, and other taxpayers whose real estate activities can involve both investment property and property held for sale.
Where Is a Section 1231 Loss Reported?
Form 4797, Sales of Business Property, is the primary federal form used to report Section 1231 property dispositions.
Under the current Form 4797 structure:
- Applicable Section 1231 gains and losses are reported in Part I.
- Line 7 determines the taxpayer's net Section 1231 gain or loss.
- A net Section 1231 loss is carried to Part II of Form 4797 as an ordinary loss.
- A net Section 1231 gain is subject to the five year lookback before any remaining gain generally receives long term capital gain treatment.
Additional forms can be required when the transaction involves passive activities, at risk limitations, casualty losses, installment sales, or like kind exchanges.
Can a Partnership or S Corporation Pass Through a Section 1231 Loss?
Yes.
A partnership generally reports an owner's share of net Section 1231 gain or loss in Schedule K1 Box 10.
An S corporation generally reports the shareholder's share in Schedule K1 Box 9.
The K1 amount then enters the owner's tax return subject to the applicable owner level limitations.
The entity cannot determine every limitation for the owner because it generally does not know the owner's complete outside basis, at risk amount, passive activity history, other Section 1231 transactions, or other investments.
Example: Partnership K1 Section 1231 Loss
Assume a real estate partnership reports a $100,000 Section 1231 loss to a partner in Box 10 of Schedule K1.
The partner cannot automatically assume that the entire $100,000 is currently deductible.
The partner must first determine whether sufficient outside basis exists, whether the loss is allowed under the at risk rules, and whether Section 469 limits the loss as passive.
Only the amount surviving the applicable owner level limitations reaches the taxpayer's current loss calculation.
Can a Current Section 1231 Loss Affect Future Property Gains?
Yes.
This is one of the most important long term consequences of receiving an ordinary Section 1231 loss deduction.
Section 1231(c) looks back to net Section 1231 losses deducted during the five preceding taxable years that have not already been applied against later Section 1231 gains.
A later net Section 1231 gain is treated as ordinary income to the extent of the taxpayer's remaining nonrecaptured Section 1231 losses.
Example: Current Ordinary Loss Creates Future Ordinary Gain Exposure
Assume a taxpayer has an allowed $120,000 net Section 1231 loss in 2026.
The 2026 loss generally has ordinary character.
In 2029, the taxpayer sells another qualifying property and has a $200,000 net Section 1231 gain.
Assuming the full $120,000 prior loss remains nonrecaptured, the first $120,000 of the 2029 net Section 1231 gain is generally treated as ordinary income under Section 1231(c).
The remaining $80,000 can generally retain long term capital gain character, subject to the other applicable rules.
For a detailed explanation, see Section 1231 Five Year Lookback Rule: When Property Gain Becomes Ordinary Income .
Does a Suspended Passive Section 1231 Loss Start the Five Year Lookback?
Not merely because the Section 1231 loss exists economically or appears on a Schedule K1.
The Form 4797 instructions describe nonrecaptured Section 1231 losses as net Section 1231 losses deducted during the five preceding taxable years that have not already been applied against later net Section 1231 gains.
If Section 469 prevents a passive Section 1231 loss from being deducted, the suspended amount should be distinguished from a Section 1231 loss that actually entered taxable income for the year.
If the suspended loss later becomes allowable, it can affect the Section 1231 computation in the year it becomes deductible and can then affect later years under the lookback rule.
How Does Real Estate Professional Status Affect a Section 1231 Loss?
Real estate professional status can affect whether a rental real estate loss is passive under Section 469.
The taxpayer must satisfy the real estate professional tests and materially participate in the applicable rental activity for rental real estate to be nonpassive.
If the activity is nonpassive, the Section 469 passive loss limitation generally does not restrict the current loss from that activity.
Other applicable limitations, including basis, at risk, and Section 461(l), can still apply.
For a detailed discussion, see Real Estate Professional Status: How Rental Property Owners Qualify and Deduct Losses .
What Should Be Reviewed Before Claiming a Large Section 1231 Loss?
A large property loss should generally be reviewed using both the disposition rules and the taxpayer's owner level loss limitations.
Important items can include:
- Original acquisition basis
- Closing costs included in basis
- Capital improvements
- Depreciation allowed or allowable
- Cost segregation studies
- Partial dispositions
- Prior Section 1031 exchanges
- Allocation of sales price among separate tax assets
- Land and building allocation
- Section 1245 and Section 1250 asset classifications
- Other current year Section 1231 gains and losses
- Partnership outside basis when applicable
- S corporation stock and debt basis when applicable
- At risk amount
- Passive or nonpassive activity status
- Suspended passive losses
- Real estate professional and material participation status when relevant
- Section 461 excess business loss exposure
- State income tax treatment
The Tax Loss Is Based on Adjusted Basis, Not Simply Economic Loss
A property declining in market value does not automatically produce an income tax loss of the same amount.
Depreciation, capital improvements, prior exchanges, cost segregation, selling expenses, debt treatment, and asset allocation can materially change the actual tax result.
Frequently Asked Questions About Section 1231 Losses
What is a Section 1231 loss?
A Section 1231 loss generally arises from a qualifying disposition of property described in Section 1231, including certain real property and depreciable property used in a trade or business and held for more than one year. The final tax character depends on the taxpayer's combined Section 1231 gains and losses for the year.
Is a Section 1231 loss an ordinary loss or capital loss?
If Section 1231 losses exceed Section 1231 gains for the year, the resulting net Section 1231 loss generally has ordinary rather than capital loss character.
Is a Section 1231 loss limited to $3,000 per year?
A net Section 1231 loss is not subject to the individual capital loss limitation merely because of its Section 1231 character. Separate basis, at risk, passive activity, and excess business loss limitations can still restrict the current deduction.
Can a Section 1231 loss offset wages or other ordinary income?
An allowed net Section 1231 loss has ordinary character and can reduce taxable income without being treated as a capital loss. Whether the loss can currently offset wages or other nonpassive income depends on separate limitations such as the passive activity rules and Section 461(l).
Is every Section 1231 loss immediately deductible?
No. The ordinary character of the loss does not override basis limitations, the at risk rules, passive activity limitations, or the excess business loss limitation.
How do passive activity rules affect a rental property Section 1231 loss?
A Section 1231 loss attributable to a passive rental activity can be limited under Section 469. Rental real estate can be nonpassive when the taxpayer qualifies as a real estate professional and materially participates in the applicable activity.
How do basis and at risk limitations affect a Section 1231 loss?
Applicable basis limitations generally restrict losses before the at risk and passive activity rules are applied. The at risk rules can then restrict losses to the taxpayer's amount at risk in the activity. These rules can defer part of an otherwise ordinary Section 1231 loss.
How does Section 461 affect a large Section 1231 loss?
Section 461(l) can limit excess business losses of noncorporate taxpayers after other applicable loss limitations. A disallowed excess business loss is generally treated as a net operating loss carryover under the current rules.
What happens when I have both Section 1231 gains and losses in the same year?
The applicable Section 1231 gains and losses are combined for the taxable year. If losses exceed gains, the resulting net Section 1231 loss generally has ordinary character. If gains exceed losses, the net gain is subject to the five year lookback rule.
Does depreciation recapture apply when property is sold at a loss?
Depreciation recapture generally requires gain on the particular depreciable asset. An asset sold for less than its adjusted basis does not itself generate gain to recapture. A property sale involving multiple separately classified assets can still contain recapture gain on one asset and Section 1231 loss on another.
How are casualty and theft losses handled under Section 1231?
Casualty and theft gains and losses involving qualifying property are subject to a special preliminary netting rule. If recognized casualty and theft losses exceed the recognized gains, those items are excluded from the normal Section 1231 netting calculation and are handled under the applicable casualty and theft reporting rules.
How do involuntary conversions fit into Section 1231?
Certain involuntary conversions of qualifying business and investment property can enter the Section 1231 calculation. Section 1033 can separately provide nonrecognition treatment for qualifying gains when its replacement requirements are satisfied.
Can a partnership or S corporation pass through a Section 1231 loss?
Yes. Partnerships generally report net Section 1231 gain or loss in Schedule K1 Box 10, and S corporations generally report it in Box 9. The owner must then apply the applicable owner level basis, at risk, passive activity, and other limitations.
Can a current Section 1231 loss affect gains for the next five years?
Yes. A net Section 1231 loss that is deducted can become a nonrecaptured Section 1231 loss. A later net Section 1231 gain during the five preceding taxable year lookback period can be treated as ordinary income to the extent of the remaining prior loss.
Does a suspended passive Section 1231 loss immediately start the five year lookback?
Not merely because the loss exists or appears on a K1. The Form 4797 lookback rules refer to net Section 1231 losses deducted during the preceding five taxable years. A loss that remains suspended under Section 469 must therefore be distinguished from one that has actually become deductible.
Where is a Section 1231 loss reported on Form 4797?
Section 1231 transactions are generally reported in Part I of Form 4797. If the annual calculation produces a net Section 1231 loss, the loss is carried to Part II of Form 4797 as an ordinary loss.
Final Takeaway
Section 1231 can provide valuable ordinary loss treatment when qualifying rental property, business real estate, or other business property is disposed of at a loss.
The favorable character rule should not be confused with an unlimited deduction rule.
A taxpayer must first calculate the gain or loss correctly at the asset level, apply any applicable depreciation recapture, combine the allowable Section 1231 transactions for the year, and then consider basis, at risk, passive activity, and excess business loss limitations.
A deductible net Section 1231 loss also becomes part of the taxpayer's future tax history. During the following five taxable years, that loss can cause otherwise favorable Section 1231 gain to become ordinary income.
For a substantial rental or business property loss, the current deduction and the future lookback consequences should therefore be considered together.
Review a Large Property Loss Before Filing the Tax Return
I assist real estate investors and business owners with Section 1231 property loss analysis, including adjusted basis, depreciation, cost segregation components, Section 1245 and Section 1250 classification, passive activity limitations, partnership and S corporation basis, at risk limitations, Section 461 excess business losses, and the future Section 1231 five year lookback.
The objective is to determine the amount and character of the current loss, identify any limitations or suspended amounts, and preserve the information needed to correctly report future property gains.
Schedule a ConsultationThis article provides general federal income tax information. Section 1231 loss treatment depends on the property, adjusted basis, depreciation history, holding period, ownership structure, activity classification, loss limitations, other current year Section 1231 transactions, and other facts. State income tax treatment can differ from federal treatment.
