Explore how special IRS rules disallow losses and may defer gains in related-party transactions, preventing taxpayers from recognizing or deducting artificial losses and manipulating tax outcomes.
The sale, exchange, or transfer of property between related parties—in which the buyer and seller share a close familial or business relationship—triggers unique tax implications that differ substantially from transactions conducted at arm’s length. Under federal tax law, notably Internal Revenue Code (IRC) Section 267 and related provisions, losses may be disallowed, and certain gains may be deferred when property is transferred within these related-party contexts. These rules are designed to prevent taxpayers from engaging in “advantageous” arrangements that artificially generate tax benefits, such as harvesting losses or shifting profits in ways that do not reflect true economic realities.
This section builds upon the foundational concepts introduced in 30.1 (Attribution of Stock Ownership; Definition of Related Parties) and integrates broader considerations found in other property disposition rules throughout Chapters 28 and 29 of this guide. Here, you will gain a comprehensive understanding of how disallowance of losses and deferred gains work, the common pitfalls to avoid, and ways to navigate these rules effectively while staying within the bounds of tax law.
While Chapter 30.1 covers specific criteria for identifying related parties, it is worth reiterating the significance of these definitions. In the context of disallowance of losses and deferred gains, “related parties” often include:
• Family members, such as parents, siblings, spouses, ancestors, and lineal descendants.
• Certain entities with shared ownership interests (e.g., a corporation and a shareholder who owns more than 50% of that corporation’s stock).
• Two corporations that are members of the same controlled group.
• Partnerships and their partners under specific ownership thresholds.
These rules cast a wide net, capturing various circumstances where common ownership or family ties could lead to non-arm’s-length pricing.
When two unrelated parties transact, the price is typically set by market forces. Losses recognized on such sales generally correspond to genuine economic declines in the property’s value. However, when the parties are related, there is an incentive—or at least an opportunity—to sell the property below fair market value in order to realize a tax loss. This artificial loss can then reduce taxable income or offset other gains on the seller’s return.
To counteract these distortions, the IRC disallows (i.e., denies) the loss on certain sales or exchanges between related parties. In effect, no loss deduction may be taken if the property is sold to a related buyer at a price below the seller’s adjusted basis. This prevents taxpayers from generating artificial tax breaks that do not reflect actual economic substance.
The primary statutory authority for the disallowance of losses between related parties is IRC Section 267. Key provisions include:
• Situations in which related parties cannot recognize any loss from the sale of property if the transaction is not conducted at true arm’s length.
• Enumerated definitions of related parties, including individuals and entities.
• Specialized rules for handling subsequent sales of the same property to unrelated third parties, which can affect the timing and character of gain recognition.
These rules may interact with other Code sections (e.g., Section 707 for transactions between a partner and partnership) to further refine or alter the tax consequences. Always review the cross-references for an integrated perspective.
Seller’s Side:
Buyer’s Side:
Future Implications:
Although Section 267 is most commonly associated with loss disallowance, certain transactions between related parties can also feature deferral of gain. The most common scenario arises when property is transferred at less than fair market value but above the seller’s basis, or when there is an “artificial” structure that shifts income or gain recognition across entities or tax years.
Notably, while most boycotts on immediate gain recognition revolve around like-kind exchanges (see Chapter 28: Nontaxable Exchanges and Involuntary Conversions) or other reorganization provisions, a related-party sale can create partial or deferred gain outcomes. In certain limited circumstances, the IRS may require the seller to defer gain until the buyer disposes of the property to an unrelated third party.
Recall from Chapter 29 that property transactions can trigger capital gains or losses, which may be subject to different rates and holding-period rules (short-term vs. long-term). When a loss is disallowed due to a related-party transaction:
• The disallowed amount does not convert into a capital-loss carryforward; it simply disappears from the seller’s perspective.
• For the buyer, the purchase price remains the basis, and if the buyer resells the property, the gain or loss is computed based on that cost basis (subject to any special offset rules).
This interplay between capital asset provisions and Section 267 underscores the importance of thorough recordkeeping, since the future sale by the buyer may partially recoup some or all of the disallowed loss in the form of reduced recognized gain.
Suppose a parent owns a piece of land with an adjusted basis of $100,000. The current fair market value is $90,000. The parent sells the land to their child for $90,000, resulting in a $10,000 realized loss.
• Because the sale is between related parties, the $10,000 loss is disallowed under Section 267.
• The parent cannot deduct the $10,000 on the parent’s tax return.
• The child’s basis in the land is $90,000 (the purchase price).
Now imagine the child sells the same land to an unrelated party for $110,000 two years later.
Consider a scenario in which a shareholder owns 80% of a corporation (making them related parties by virtue of ownership). The shareholder transfers an appreciated asset with an adjusted basis of $50,000 and a fair market value of $70,000 to the corporation for $70,000. Although there is a $20,000 realized gain, special related-party provisions might impact the timing of that gain recognition if the sale is structured in a way that effectively lacks economic substance or defers the corporation’s assumption of risk and reward.
In most straightforward circumstances, the gain is recognized immediately, because the asset was sold for fair market value. However, if the transaction is structured to shift the asset “temporarily” and reacquire it or shift the gain into a lower-taxed affiliate, the IRS may scrutinize the arrangement and require recognition of the gain or deferral until a subsequent bona fide sale to an unrelated party. Careful planning is critical to avoid inadvertently creating a deferral trap or violating step-transaction doctrines.
Below is a simplified Mermaid.js flowchart illustrating the high-level process of disallowance in a related-party sale. This diagram focuses on the initial decision to disallow a loss and the subsequent effects on basis.

Explanation:
One of the more nuanced elements of related-party transactions is the interplay of multiple basis rules when the buyer eventually sells the property. The basic approach:
This overlay of rules can be summarized in a mini-table:
Scenario | Seller’s Treatment | Buyer’s Basis | Future Buyer’s Sale Treatment |
---|---|---|---|
Sale to Related Party at a Loss | Loss Disallowed | Purchase Price | May partially offset future gain if certain conditions are met |
Sale to Related Party at a Gain | Typically Recognized, unless deferred or otherwise restricted | Purchase Price | Buyer’s gain or loss computed normally at sale to unrelated party |
Subsequent Sale Above Buyer’s Basis | No direct effect on Seller (disallowed loss does not carry back) | Purchase Price | Disallowed loss may reduce recognized gain if it exceeds original Seller’s basis |
Subsequent Sale Below Buyer’s Basis | No direct effect on Seller | Purchase Price | Buyer claims the loss if permissible; disallowed loss from prior transaction is lost |

Installment Sales to Related Parties (IRC Section 453)
• Avoid Artificial Price Manipulation: Ensure the transaction price aligns closely with fair market value. Overly discounted or inflated sale prices to or from related parties frequently face challenges.
• Maintain Detailed Documentation: Appraisals, third-party valuations, or comparable sales can help legitimize the transaction price.
• Use Clear Transfer Agreements: Written agreements that delineate each party’s rights and obligations make the transaction appear less suspect to the IRS.
• Check Attribution Rules: Be mindful of indirect relationships. Stock ownership attribution and constructive ownership rules often catch taxpayers off guard. A transaction could be disallowed or deferred, even if the direct relationship is not immediately obvious.
• Consider Timing and Subsequent Dispositions: If you anticipate a rapid resale to an unrelated party, plan for the possibility of reducing recognized gain by the previously disallowed loss, provided the transaction structure meets applicable requirements.
Underestimating the Breadth of “Related” Status
Many taxpayers focus on immediate family (e.g., a parent to a child) but overlook more nuanced entity-to-owner relationships (e.g., a shareholder to a corporation). Failing to recognize these broader relationships can lead to unanticipated disallowances or deferrals.
Misapplying “Fair Market Value”
A hastily determined or undocumented valuation can prompt IRS scrutiny. If the IRS deems the sale price inappropriate, it may recharacterize the transaction and disallow or adjust the resulting losses and gains.
Overlooking Future Consequences
Losses disallowed today can have ramifications on reporting future gains. Taxpayers might incorrectly compute gain or fail to recapture a previously disallowed loss, causing both over- and underpayment of taxes.
Inadvertent Partial Gifts
Selling property to a relative at below fair market value out of generosity can create complicated basis computations. This can result in a mixture of sale and gift treatment with separate rules for each portion of the transaction.
Conflating Installment Sales Rules
Special restrictions apply to installment sales between related parties. Inadvertently ignoring these can accelerate income recognition or disallow certain deferrals.
A father owns a small apartment building (rental property) with an adjusted basis of $350,000. The father’s adult son wants to acquire it to continue operating the rental business. Because both father and son prefer to keep the property in the family, they negotiate a purchase price of $320,000—lower than the fair market value of $340,000. Here’s how the transaction might unfold:
Father’s Realized Loss
• The father has a realized loss of $30,000 ($320,000 – $350,000).
• Under Section 267, this loss is disallowed, meaning it cannot be deducted on the father’s return.
Son’s Basis
• The son’s basis is $320,000.
• If the son sells the building at a future date, the father’s disallowed loss may partially reduce the son’s recognized gain if certain conditions are met and the son sells the property above the father’s original cost.
Rental Operations
• From the point of acquisition, the son will depreciate the building starting at $320,000 (adjusted for allocated land value).
• He will not receive a direct tax basis boost from the father’s disallowed loss.
Subsequent Sale
• Suppose two years later, the son sells the property for $360,000 to an unrelated party.
• Normally, the son’s gain would be $40,000 ($360,000 – $320,000).
• Because the father’s disallowed loss was $30,000, the son may be able to offset some of this gain, effectively recognizing only $10,000. The specific calculation depends on satisfying the criteria for the “gain offset” under Section 267(d).
This scenario underscores how disallowance of the loss at the time of the related-party sale can preserve part of the “lost value” for offset against a future gain, albeit subject to strict conditions.
The following diagram illustrates the subsequent offset mechanism, showing how a buyer’s future gain on a sale to an unrelated party can be reduced by the seller’s disallowed loss (subject to code requirements):

• Documentation: Maintain detailed appraisals or evidence that supports the sale price. Reconstruct how you arrived at fair market value and record negotiations.
• Substantiation of Family or Ownership Ties: In an audit, the IRS may request proof of the exact nature of relationships. Have corporate ownership records and family genealogies ready if needed.
• Consistent Treatment: If a loss is disallowed, ensure that is consistently applied in your tax return and that basis is properly recorded for the buyer. Mismatches can trigger future inquiries.
• Cross-Check with State Laws: Some states mirror or adopt the federal approach, while others have unique rules. Check local regulations for potential differences in how losses and gains are recognized among related parties.
