IRC 737: Precontribution Gain on Partnership Distributions

Q: What is 'net precontribution gain' for purposes of IRC 737?

Net precontribution gain is the net gain that the distributing partner would have recognized under IRC 704(c)(1)(B) if, immediately before the distribution, the partnership had distributed to all other partners their proportionate shares of all property that the distributing partner had contributed to the partnership within the seven-year period ending on the date of the current distribution. In plain terms, it is the aggregate unrealized appreciation in contributed property still held by the partnership as of the distribution date, measured from the contributing partner's perspective. Properties contributed more than seven years before the distribution date are excluded from the net precontribution gain calculation. Losses in contributed property offset gains to arrive at the net figure. Verify the current definition and its interaction with Treas. Reg. 1.737-1 at IRS.gov.

Q: How does IRC 737 interact with IRC 704(c)(1)(B)?

IRC 704(c)(1)(B) and IRC 737 operate from opposite angles but share a common premise. Under IRC 704(c)(1)(B), when a partnership distributes contributed property to a partner other than the original contributor within seven years of contribution, the contributor must recognize gain or loss on the distribution as if the property had been sold at its fair market value. Under IRC 737, the reverse situation triggers gain: the contributor themselves receives non-contributed property from the partnership. If both provisions could apply to the same distribution, IRC 737 applies only to the extent it exceeds the amount already recognized under IRC 704(c)(1)(B). Practitioners must sequence the two computations -- 704(c)(1)(B) first, then 737 -- for any distribution occurring within the seven-year window. Verify the ordering rule at IRS.gov and in Treas. Reg. 1.737-1 and 1.704-4.

Q: What basis adjustments result from IRC 737 gain recognition under IRC 737(c)?

Under IRC 737(c), two concurrent basis adjustments are required after IRC 737 gain is recognized. First, the distributing partner's outside basis in the partnership interest is increased by the amount of gain recognized under IRC 737(a). This increase is applied immediately before the distribution is treated as reducing the partner's outside basis under IRC 733. Second, the partnership's adjusted basis in the contributed property that gave rise to the net precontribution gain is increased by the same amount. This inside basis increase prevents the partnership from later recognizing gain on that contributed property that was already taxed at the partner level through the IRC 737 mechanism. The two adjustments are parallel and equal in amount. Verify the basis adjustment mechanics under IRC 737(c) and Treas. Reg. 1.737-3 at IRS.gov.

Q: How is the IRC 737 gain characterized -- capital or ordinary?

The character of IRC 737 gain is determined by the character of the net precontribution gain in the contributed property that generated it. If the contributed property would have produced capital gain had it been sold at the time of the distribution, the IRC 737 gain is capital. If the contributed property included ordinary income property (for example, inventory or accounts receivable), the portion of net precontribution gain attributable to that ordinary income property is ordinary income. Where the net precontribution gain derives from a mix of capital-gain property and ordinary income property, the IRC 737 recognized gain is allocated proportionately between capital and ordinary character. Verify the character rules and their interaction with IRC 751 hot asset ordinary income at IRS.gov and in Treas. Reg. 1.737-1(d).

Q: Does IRC 737 apply when money, rather than property, is distributed?

No. IRC 737 applies only when the distributing partner receives property other than money in the distribution. A cash distribution does not trigger IRC 737. However, a cash distribution reduces the partner's outside basis under IRC 733, and if the cash exceeds outside basis, IRC 731(a)(1) governs gain recognition on the excess. Marketable securities may be treated as money under IRC 731(c), which removes them from IRC 737 analysis and subjects them instead to the IRC 731(c) rules. Practitioners should determine whether any distributed asset qualifies as a marketable security before applying IRC 737. Verify the marketable security treatment and the boundary between IRC 731 and IRC 737 at IRS.gov and in the current Code.

Q: What is the effect of the seven-year period on IRC 737 planning?

The seven-year period is the central planning horizon for IRC 737. Once seven years have elapsed from the date of contribution, property contributed by the partner drops out of the net precontribution gain calculation entirely. A distribution of other property occurring more than seven years after all of the partner's contributions carry zero IRC 737 exposure from those contributions. Conversely, distributions within seven years require the practitioner to inventory all contributions made during the preceding seven years, compute the unrealized appreciation in each contributed property still held by the partnership, net gains against losses, and then apply the IRC 737(b) lesser-of test. The seven-year period runs from the actual contribution date, not the partnership's taxable year. Verify the precise start and end of the seven-year period under IRC 737(d) and IRS.gov.

Q: How does IRC 737 interact with IRC 751 hot assets on a distribution?

IRC 751(b) governs distributions involving hot assets -- unrealized receivables and substantially appreciated inventory. When a distribution would shift a partner's proportionate share of hot assets (either the partner receives more hot assets than their share, or receives non-hot assets in exchange for a reduction in their hot asset share), IRC 751(b) recharacterizes part of the transaction as a deemed sale, producing ordinary income. The IRC 737 analysis is separate and must be performed independently. Both provisions can apply to the same distribution, and the amounts do not offset each other. The practitioner must complete the IRC 751(b) analysis first, then separately compute and recognize any IRC 737 precontribution gain. Verify the interaction and the ordering of computations at IRS.gov and in Treas. Reg. 1.751-1(b) and 1.737-1.

Key Points

IRC 737(a) requires a contributing partner to recognize gain when the partnership distributes other property to them within seven years of the contribution -- the rule prevents partners from using the partnership as a tax-free exchange vehicle for appreciated property.
The recognized gain equals the lesser of (i) the partner's net precontribution gain on all contributed properties still within the seven-year window, or (ii) the excess of the fair market value of the distributed property over the partner's adjusted outside basis immediately before the distribution.
IRC 737(c) provides automatic basis relief: the partner's outside basis and the partnership's inside basis in the contributed property are each increased by the amount of gain recognized, preventing double taxation.
IRC 737 and IRC 704(c)(1)(B) share the same seven-year look-back and the same contributed-property premise. They must be analyzed together; 704(c)(1)(B) is applied first, and any IRC 737 gain is reduced by the amount recognized under that provision.
The character of IRC 737 gain mirrors the character of the net precontribution gain in the contributed property: capital or ordinary based on the nature of the contributed asset.
IRC 751(b) hot asset analysis is a separate, concurrent obligation. Both IRC 737 and IRC 751(b) can apply to the same distribution, and the computations do not offset each other. Verify all mechanics at IRS.gov and in the current Code and Treasury Regulations before advising any client.

When a partner contributes appreciated property to a partnership and later receives a distribution of different property, IRC 737 closes the loop that IRC 731's general nonrecognition rule would otherwise leave open. Without IRC 737, a partner could contribute appreciated property -- deferring the built-in gain -- and then effectively swap it for other property through a tax-free partnership distribution. Congress enacted IRC 737 in 1992 precisely to prevent that result. For tax practitioners advising on partnership distributions where contributed property is in the picture, IRC 737 is not optional analysis. Overlooking it causes an understatement of taxable income on the contributing partner's return.

Section 1: The Statutory Problem IRC 737 Solves

The nonrecognition gap IRC 737 closes

Under IRC 721, a partner generally contributes property to a partnership without recognizing gain or loss. Under IRC 731, a partnership generally distributes property to a partner without the partner recognizing gain (except to the extent cash exceeds outside basis). Together, those two provisions created a planning opportunity before 1992: a partner with appreciated property (say, real estate with a $200,000 basis and $1,000,000 fair market value) could contribute it to a partnership, wait for a distribution of different property (say, marketable securities), and walk away with those securities at a low carryover basis -- the deferred gain sitting in the contributed real estate preserved for later, or never, recognition.

IRC 737, enacted by the Revenue Reconciliation Act of 1992, addresses that gap by requiring the contributing partner to recognize the precontribution gain built into contributed property whenever a distribution of other property occurs within seven years of the contribution and the distribution's value exceeds the partner's outside basis. The provision pairs with IRC 704(c)(1)(B), which applies the mirror image: when contributed property is distributed to a partner other than the contributor within seven years, the contributor recognizes gain on that event. Together, the two provisions form a seven-year perimeter around contributed appreciated property.

Compliance Risk: Understatement of Taxable Income

Failing to apply IRC 737 when a contributing partner receives property distributions within seven years of their contribution is a direct understatement of taxable income. Because the gain does not appear on the distribution itself (IRC 731 would show no gain if outside basis exceeds the distributed property's basis), it is easy to miss in return preparation. Always check: (1) Did this partner contribute appreciated property within the past seven years? (2) Has the partnership distributed other property to this partner? If yes to both, IRC 737 analysis is required. Verify the full scope of the obligation at IRS.gov and in Treas. Reg. 1.737-1 before completing the partner's return.

The general nonrecognition backdrop: IRC 731

IRC 731(a) sets the general rule: a partner does not recognize gain on a distribution from a partnership except to the extent that any money distributed exceeds the partner's adjusted basis in the partnership interest. IRC 731(b) provides parallel nonrecognition to the partnership. IRC 737 operates as a specific exception to IRC 731(a) for partners who contributed appreciated property. When IRC 737 applies, the contributing partner recognizes gain on the distribution even if the general rule of IRC 731(a) would produce no gain. The distributed property's basis in the partner's hands is then determined under IRC 732, not at fair market value -- a fact that matters for planning and for downstream reporting.

Section 2: IRC 737(a) -- Gain Recognition Rule

IRC 737(a) states the basic recognition rule: in the case of any distribution by a partnership to a partner, such partner shall recognize gain in an amount equal to the lesser of:

The partner's net precontribution gain (defined in IRC 737(d) and discussed in Section 4 of this guide), or
The excess of the fair market value of the property distributed over the adjusted basis of the partner's interest in the partnership immediately before the distribution (outside basis before the distribution, but after any reduction for money distributed in the same transaction).

If either amount is zero or negative, no IRC 737 gain is recognized. The trigger is a distribution of property other than money. Cash distributions and distributions of marketable securities treated as money under IRC 731(c) do not trigger IRC 737, though they do reduce the partner's outside basis under IRC 733, which affects future IRC 737 exposure.

The "other property" requirement

IRC 737 applies only to distributions of property other than money. If the partnership distributes back to the contributing partner the exact same property the partner originally contributed, IRC 737 does not apply -- that distribution is covered instead by the anti-abuse rules and the general nonrecognition framework. The classic IRC 737 trigger is a kind-for-kind swap: Partner A contributes appreciated land; the partnership later distributes appreciated securities (contributed by Partner B) to Partner A. In that scenario, Partner A has effectively exchanged the land for the securities through the partnership without recognizing gain under IRC 731 -- and IRC 737 is designed to prevent that.

Practitioner Note: Sequence Basis Reductions Correctly

When computing the IRC 737(a) lesser-of test, the partner's outside basis used in prong (ii) is the outside basis immediately before the distribution, reduced first by any money distributed in the same distribution. If the distribution includes both cash and property, reduce outside basis by the cash component before applying the IRC 737 test to the property component. Misordering the computation understates the exposure. Verify the sequencing rule under Treas. Reg. 1.737-1(b) and IRS.gov before completing the computation.

Section 3: IRC 737(b) -- Computing the Amount of Gain

IRC 737(b) codifies the lesser-of formula in two distinct prongs. The gain recognized is the lesser of:

Prong 1: Net precontribution gain

This prong captures the total unrealized appreciation the partner built into contributed property that the partnership still holds within the seven-year window. It is the maximum the partner can be required to recognize under IRC 737, regardless of how valuable the distributed property is. If the partner's contributed property has no unrealized gain (or shows a net loss), this prong is zero or negative, and no IRC 737 gain results from any distribution, no matter how large.

Prong 2: Excess of FMV of distributed property over outside basis

This prong limits IRC 737 recognition to the economic gain the partner would have realized had they sold the distributed property at its fair market value on the distribution date, measured against their outside basis. It prevents IRC 737 from taxing the partner on more gain than the distributed property's FMV minus outside basis would produce -- a cap that protects against recognition exceeding what an actual arm's-length sale would generate.

The lesser of the two prongs is the gain the partner must recognize. When the outside basis is high relative to the distributed property's FMV, Prong 2 constrains the result. When the contributed property's built-in gain is modest relative to the distribution's value, Prong 1 is the binding constraint.

Practitioner Note: Net Precontribution Gain Includes Losses

Net precontribution gain is a net figure. If the partner contributed multiple properties within the seven-year window, the built-in gains and losses across all those properties are netted. A contributed property with a built-in loss reduces the net precontribution gain and therefore reduces (or eliminates) IRC 737 exposure. However, a net loss position does not create a recognized loss under IRC 737 -- the provision is gain-only. Only gains are forced out. Losses remain in the partnership's hands subject to ordinary distribution and sale rules. Verify the netting calculation mechanics under Treas. Reg. 1.737-1(c) and IRS.gov.

Section 4: Net Precontribution Gain -- Definition and Calculation

IRC 737(d) defines net precontribution gain as the net gain, if any, that would have been recognized by the distributee partner under IRC 704(c)(1)(B) if, immediately before the distribution:

the partnership had distributed to each of the other partners their proportionate shares of all property that the distributing partner had contributed within the seven-year period ending on the date of the current distribution, and
those deemed distributions had triggered IRC 704(c)(1)(B) recognition by the distributing partner.

In practical terms: for each property contributed by this partner within the past seven years that the partnership still holds, compute the difference between the property's current fair market value and its adjusted tax basis in the partnership's hands (the carryover basis from the contribution). Sum the gains across all such properties. Subtract any built-in losses. The net result is the net precontribution gain.

Key attributes of the net precontribution gain figure

Seven-year cutoff is hard. Only contributions made within the seven years ending on the distribution date count. Contributions more than seven years old are excluded entirely, even if the contributed property still has large unrealized appreciation.
Only property the partnership still holds counts. If the partnership previously disposed of contributed property in a taxable sale, any IRC 704(c)(1)(B) gain was recognized at that time. That property no longer contributes to the net precontribution gain pool for IRC 737 purposes.
Appreciation measured at distribution date. The fair market value is measured at the time of the current distribution, not at the original contribution date. Post-contribution appreciation (or depreciation) in the contributed property is reflected in the computation.
Multiple contributors. Each partner's net precontribution gain is computed independently for that partner's contributions. One partner's contributed property does not affect another partner's IRC 737 analysis, even if both contributed appreciated property.

Section 5: IRC 737(c) -- Basis Adjustments After Gain Recognition

Once IRC 737(a) gain is recognized, IRC 737(c) mandates two basis adjustments that work together to prevent double taxation of the same economic appreciation:

Adjustment 1: Partner's outside basis increased

The distributing partner's adjusted basis in the partnership interest is increased by the amount of gain recognized under IRC 737(a). This outside basis increase is applied immediately before the distribution is treated as reducing outside basis under IRC 733. The sequence matters: recognize gain first (increasing outside basis), then reduce outside basis by the distribution amount under IRC 733. This sequencing ensures the partner is not left with a negative outside basis simply because the IRC 737 gain recognition occurred.

Adjustment 2: Partnership's inside basis in contributed property increased

The partnership's adjusted basis in the contributed property (the property that generated the net precontribution gain) is increased by the same amount of gain the partner recognized. This inside basis step-up prevents the partnership from later recognizing gain in the contributed property that has already been taxed at the partner level under IRC 737. Without this adjustment, the partnership's eventual sale of the contributed property would generate gain that had already been taxed through the IRC 737 mechanism -- double taxation.

If the IRC 737 gain is allocated among multiple contributed properties (because the net precontribution gain derives from more than one contributed property), the inside basis increase is allocated among those properties proportionately to their respective built-in gains. Verify the allocation mechanics under Treas. Reg. 1.737-3 at IRS.gov.

Practitioner Note: Distributed Property Basis Is Still Governed by IRC 732

IRC 737 gain recognition does not change the basis rules for the distributed property itself. The partner takes a basis in the distributed property under IRC 732 (generally, the lesser of the partnership's adjusted basis in the property or the partner's outside basis after the IRC 737 adjustment and before the distribution reduces outside basis). IRC 737 does not step up the basis of the distributed property to fair market value. This is a common source of confusion: the partner recognizes gain under IRC 737 but still takes a carryover or substituted basis in the distributed property under IRC 732, not a cost basis. Verify the basis-in-distributed-property rules under IRC 732 and Treas. Reg. 1.732-1 at IRS.gov.

Section 6: Character of IRC 737 Gain

The character of IRC 737 gain -- capital or ordinary -- is not independently determined. Instead, it is derived from the character of the net precontribution gain in the contributed property. Treas. Reg. 1.737-1(d) establishes the character rules.

Capital gain character

If the contributed property that generated the net precontribution gain is a capital asset (for example, investment land, investment securities, or an IRC 1231 asset that would produce net capital gain), the IRC 737 gain is capital in character. Long-term or short-term capital treatment depends on the holding period of the contributed property as of the distribution date. Verify the holding period rules under applicable Treasury Regulations and IRS.gov.

Ordinary income character

If the contributed property is ordinary income property -- such as inventory, accounts receivable, or property subject to depreciation recapture under IRC 1245 or 1250 -- the portion of net precontribution gain attributable to that property is ordinary income. This rule reflects the principle that IRC 737 should not change the character of what would have been ordinary income if the partner had sold the contributed property directly.

Mixed character: proportionate allocation

When the net precontribution gain includes both capital gain property and ordinary income property, the IRC 737 recognized gain is allocated proportionately between capital and ordinary character based on the relative amounts of gain from each type of property in the net precontribution gain pool. If the pool is 60% capital gain and 40% ordinary income, the IRC 737 recognized amount is split 60/40 accordingly. Verify the proportionate allocation methodology under Treas. Reg. 1.737-1(d) and IRS.gov before completing Schedule K-1 allocations.

Compliance Risk: Ordinary Income in Contributed Depreciable Property

Partners frequently contribute depreciated or appreciated business personal property (equipment, vehicles, leasehold improvements) where IRC 1245 recapture lurks in the contributed asset's depreciation history. If such property is part of the contributed property pool, the IRC 1245 recapture portion of the built-in gain is ordinary income that flows through to the IRC 737 character computation. Mischaracterizing this as capital gain is an understatement of ordinary income -- a more consequential error than a capital-vs-capital misclassification given the tax rate differential. Always review the contributed property's depreciation history before characterizing IRC 737 gain. Verify at IRS.gov and Treas. Reg. 1.737-1(d).

Section 7: The Seven-Year Look-Back Period

IRC 737(d)(1) ties the net precontribution gain definition to the seven-year period ending on the date of the distribution. Only contributions made within that period are included. The seven-year period runs contribution-date to distribution-date, not by reference to partnership taxable years. A contribution made on January 15, 2019, drops out of the pool for any distribution occurring after January 15, 2026.

IRC 737 also shares its seven-year period with IRC 704(c)(1)(B). Both provisions use the identical look-back structure. As a practical matter, both should be evaluated together any time a distribution occurs and any partner has a contribution within the past seven years. Verify the exact statutory language of the seven-year period at IRS.gov and in the current Code before concluding that any particular contribution has aged out.

Tolling and interruptions

The seven-year clock does not run during certain events. Specifically, Treasury Regulations provide that the seven-year period may be tolled or re-started in certain reorganization and restructuring transactions where a partnership's assets are carried over into a successor entity. If a partner's interest in a partnership is transferred or the partnership itself is restructured, practitioners must determine whether the contributed property's seven-year clock continues to run or is reset. Verify the tolling rules applicable to specific transactions under Treas. Reg. 1.737-2 and IRS.gov before advising any client on the effect of a restructuring on IRC 737 exposure.

Section 8: Interaction with IRC 704(c) -- The Two Provisions Must Be Analyzed Together

IRC 704(c) is the foundational contributed-property provision. Under IRC 704(c)(1)(A), income, gain, loss, and deduction attributable to property contributed to a partnership must be allocated among the partners to take into account the difference between the property's tax basis and its book value (fair market value at contribution). This is the "reverse 704(c)" or "book-tax difference" that practitioners track for each contributed property throughout the life of the partnership.

IRC 704(c)(1)(B) is the provision that overlaps most directly with IRC 737. Under IRC 704(c)(1)(B), if contributed property is distributed to a partner other than the contributor within seven years, the contributor recognizes gain or loss as if the property had been sold at fair market value on the distribution date. IRC 737 is the complement: it applies when the contributor receives a distribution of other property within seven years.

The ordering rule when both provisions could apply

When the same distribution could trigger both IRC 704(c)(1)(B) and IRC 737, the Regulations establish an ordering rule: IRC 704(c)(1)(B) is applied first, and any IRC 737 gain is reduced (but not below zero) by the gain already recognized under IRC 704(c)(1)(B) in the same distribution event. This coordination prevents double counting the same precontribution gain in a single distribution.

The scenario that triggers both provisions simultaneously is a cross-distribution: the partnership distributes Property X (which Partner A contributed) to Partner B, while simultaneously distributing Property Y (which Partner B contributed) to Partner A. Partner A recognizes gain under IRC 704(c)(1)(B) on the distribution of their contributed Property X to Partner B. Partner A also potentially recognizes gain under IRC 737 on receiving Property Y. The IRC 704(c)(1)(B) amount is computed and recognized first, then applied against the IRC 737 net precontribution gain pool to determine the remaining IRC 737 exposure. Verify the ordering rule under Treas. Reg. 1.737-1(a) and Treas. Reg. 1.704-4 at IRS.gov.

Section 9: Interactions with IRC 731 and IRC 732

IRC 731: General nonrecognition

IRC 731(a) is the default rule: no gain or loss on a distribution unless money exceeds outside basis. IRC 737 is an explicit exception to IRC 731(a). When IRC 737 applies, the contributing partner recognizes gain on the distribution even if IRC 731(a) would otherwise produce zero gain. The two provisions are not in conflict -- they occupy separate domains. IRC 731 handles the general case; IRC 737 overrides it for contributing partners within the seven-year window.

For distributions to non-contributing partners (partners with no contributed property within the seven-year window), IRC 737 is irrelevant and IRC 731 governs entirely. IRC 737 is exclusively the concern of contributing partners.

IRC 732: Basis in distributed property

The basis the contributing partner takes in the distributed property is governed by IRC 732, not by the amount of IRC 737 gain recognized. IRC 732(a) provides that in a current distribution (other than a liquidating distribution), the partner takes a basis in the distributed property equal to the lesser of the partnership's adjusted basis in the property immediately before the distribution or the partner's outside basis in the partnership interest (reduced by any money received in the same distribution, and increased by the IRC 737(c) basis adjustment for recognized gain).

The interaction of IRC 737(c) and IRC 732 is critical: after IRC 737 gain is recognized and outside basis is stepped up under IRC 737(c), the IRC 732 computation uses the post-step-up outside basis as the cap. This can result in a higher basis in the distributed property than would exist if the IRC 737(c) increase were omitted -- which is part of the legislative design. Verify the exact sequencing of basis computations under IRC 732 and Treas. Reg. 1.732-1 at IRS.gov.

Section 10: Interaction with IRC 751 Hot Assets

IRC 751(b) governs distributions that alter a partner's proportionate share of hot assets -- unrealized receivables and substantially appreciated inventory. When a distribution shifts the partner's effective economic interest in hot assets relative to non-hot assets, IRC 751(b) treats part of the transaction as a deemed sale between the partner and the partnership, generating ordinary income or gain.

IRC 737 and IRC 751(b) analyze the same distribution from different angles and must both be applied. They are separate analyses and the amounts do not offset or reduce each other. A distribution of appreciated non-hot assets that triggers IRC 737 precontribution gain may also trigger IRC 751(b) ordinary income if the distribution affects the partner's hot asset share. The practitioner must:

Complete the IRC 751(b) analysis for the distribution, identifying any hot asset exchange and the ordinary income that results.
Separately complete the IRC 737 analysis, computing net precontribution gain and the lesser-of test.
Report both amounts on the partner's return, keeping their character determinations separate. The IRC 737 gain reflects precontribution appreciation in contributed property; the IRC 751(b) amount reflects ordinary income from hot asset exposure. Verify the combined reporting at IRS.gov.

For the IRC 751 hot assets analysis, see also the IRC 707 disguised sales and guaranteed payments practitioner guide, which covers how IRC 707 recharacterization interacts with the same distribution transaction analysis.

Section 11: Example Computations

The examples below illustrate common IRC 737 scenarios. All dollar amounts are hypothetical. Verify the applicable rules and their current status at IRS.gov and in the current Code and Treasury Regulations before applying any analysis to a client situation.

Example 1: Basic IRC 737 Computation

Partner A contributes land (tax basis $100,000; FMV $400,000) to a partnership in Year 1. In Year 4, the partnership distributes to Partner A marketable securities with FMV $250,000 (which are not treated as money under IRC 731(c) in this example). At the time of distribution, Partner A's outside basis is $160,000, and the land is still held by the partnership with a current FMV of $450,000 (basis $100,000).

Net precontribution gain (Prong 1): $450,000 FMV less $100,000 basis = $350,000. Prong 2: $250,000 FMV of distributed property less $160,000 outside basis = $90,000. IRC 737(a) recognized gain: lesser of $350,000 and $90,000 = $90,000. IRC 737(c) adjustment: Partner A's outside basis increases by $90,000 to $250,000 before the distribution reduces it. Partnership's inside basis in the land increases by $90,000 to $190,000.

IRC 737 Scenario Reference Table

Scenario	Net Precontribution Gain (Prong 1)	FMV Distributed Less Outside Basis (Prong 2)	IRC 737 Gain Recognized	Notes / Interaction

Two contributed properties: Property 1 has $200K gain; Property 2 has $50K built-in loss; outside basis $80K; distributed property FMV $200K	$150,000 (netted: $200K gain less $50K loss)	$120,000	$120,000 (Prong 2 controls)	Built-in loss from Property 2 reduces the net precontribution gain pool; inside basis step-up allocated proportionately among contributed properties with gains
Contribution older than seven years: contribution made eight years before distribution; all other facts same as basic example	$0 (contribution outside seven-year window)	$90,000	$0 (no net precontribution gain)	Property contributed more than seven years before distribution is excluded from IRC 737 analysis entirely; IRC 731 governs the distribution without IRC 737 override
Cash distribution only: partner with net precontribution gain receives $100,000 cash; no property distributed	$350,000	N/A -- no property distributed	$0 (IRC 737 does not apply to money distributions)	Cash reduces outside basis under IRC 733; if cash exceeds outside basis, gain under IRC 731(a)(1), not IRC 737; seven-year clock continues to run; future property distributions still subject to IRC 737
704(c)(1)(B) and 737 both triggered in same distribution: Partner A receives Property B (FMV $150K) while Property A (contributed by A, FMV $200K, basis $80K) is distributed to Partner B	$120,000 (FMV of Property A less basis)	$70,000 (FMV of Property B less Partner A's outside basis of $80K)	IRC 704(c)(1)(B) gain recognized first on Property A distribution: $120K. IRC 737 gain: lesser of ($120K less $120K already recognized = $0) and $70K = $0.	Ordering rule: 704(c)(1)(B) recognized first; IRC 737 gain reduced by 704(c)(1)(B) amount; in this example, 704(c)(1)(B) exhausts the precontribution gain pool, eliminating IRC 737 gain; verify ordering under Treas. Reg. 1.737-1(a)
Ordinary income property contributed: depreciable equipment, basis $50K, FMV $150K at distribution; IRC 1245 recapture $60K; distributed property FMV $90K; outside basis $40K	$100,000 (FMV $150K less basis $50K)	$50,000	$50,000 ($60K ordinary component exceeds Prong 2 result; entire $50K recognized is ordinary income because recapture portion exceeds the recognized amount)	Character derived from contributed property: IRC 1245 recapture in contributed equipment makes the recognized amount ordinary income; verify character rules under Treas. Reg. 1.737-1(d)
Liquidating distribution: partnership liquidates, contributing partner receives property other than contributed property in full liquidation	Computed same as current distributions	Computed using outside basis before liquidating distribution	IRC 737 applies to liquidating distributions if within seven years; Prong 2 uses outside basis before liquidating distribution; IRC 732(b) governs basis in distributed property in liquidation	IRC 732(b) (not IRC 732(a)) applies to basis in distributed property in a liquidating distribution; IRC 737(c) basis adjustments still apply; verify under Treas. Reg. 1.737-1 and 1.732-1(b)
IRC 754 election in effect: same facts as basic example; does the 754 election affect IRC 737?	$350,000	$90,000	$90,000 (IRC 754 election does not reduce IRC 737 gain)	IRC 754 / IRC 734(b) adjustments to inside basis on distributions are separate from IRC 737; a 734(b) adjustment to other partnership assets does not reduce the IRC 737 gain; IRC 737(c) inside basis increase in contributed property runs independently; verify under Treas. Reg. 1.734-1 and 1.737-3
Partner's outside basis increased by partnership liabilities: outside basis includes share of partnership debt under IRC 752; distributed property FMV $250K; outside basis (including debt) $220K	$350,000	$30,000	$30,000 (Prong 2 controls; liability-augmented outside basis reduces exposure)	Partner's outside basis includes their share of partnership liabilities under IRC 752; a larger debt share means higher outside basis, which shrinks Prong 2; see the IRC 752 liability allocation guide for outside basis and debt-share mechanics
Partial seven-year window: two contributions within seven years (each with $80K gain); one contribution is eight years old (with $200K gain); distributed property FMV $100K; outside basis $60K	$160,000 (only the two in-window contributions count: $80K + $80K; the $200K from the eight-year-old contribution is excluded)	$40,000	$40,000 (Prong 2 controls; the excluded aged-out contribution is immaterial to this result)	Seven-year look-back applied property by property, contribution by contribution; each contribution's date is tracked independently; verify the date-by-date look-back rule under IRC 737(d)(1) and Treas. Reg. 1.737-1(c)

Section 12: Reporting IRC 737 Gain

IRC 737 gain is reported by the distributing partner on their individual (or entity) income tax return for the year in which the distribution occurs. The partnership is responsible for identifying IRC 737 events and providing information to the partner on Schedule K-1 sufficient to complete the calculation. The partnership must track:

The contribution date, tax basis, and FMV at contribution for each contributed property that is still within the seven-year window.
The current FMV of each such property at the time of a triggering distribution.
The distributing partner's outside basis immediately before the distribution.
Any amounts already recognized under IRC 704(c)(1)(B) in the same transaction that must reduce the IRC 737 gain computation.

The IRC 737 gain is reported on the partner's return in the character determined under Section 6 of this guide (capital or ordinary). Capital gain flows to Schedule D; ordinary income flows through the appropriate line. Verify the current reporting lines and Schedule K-1 code assignments at IRS.gov and in the current Form 1065 and Schedule K-1 instructions before completing any return.

Partnerships that have terminated or changed status within the seven-year window present additional tracking complexity. For partnership termination rules and their effect on seven-year clocks, see the IRC 708 partnership termination practitioner guide in the Related Guides section below. For the IRC 761 definition of a partnership and the threshold questions about whether an arrangement qualifies as a partnership at all (which determines whether IRC 737 even applies), see the IRC 761 partnership definition practitioner guide in the Related Guides section below.

Frequently Asked Questions

What triggers IRC 737 gain recognition on a partnership distribution?

IRC 737 is triggered when a partner who contributed appreciated property to a partnership within the preceding seven years receives a distribution of other property from the partnership. The partner must recognize gain equal to the lesser of (1) the partner's net precontribution gain on all properties contributed within seven years, or (2) the excess of the fair market value of the distributed property over the partner's adjusted outside basis immediately before the distribution (after reducing for any money distributed in the same transaction). If either amount is zero or less, no IRC 737 gain is recognized. Verify the seven-year period and all thresholds at IRS.gov and in the current Code before advising any client.

What is "net precontribution gain" for purposes of IRC 737?

Net precontribution gain is the aggregate unrealized appreciation in contributed property still held by the partnership, measured from the contributing partner's perspective, across all properties contributed by that partner within the seven-year window ending on the distribution date. It is computed as if the partnership had immediately before the distribution distributed all such contributed property to the other partners under IRC 704(c)(1)(B), triggering the contributor's gain on that deemed distribution. Losses in contributed property within the window reduce the gain. Properties contributed more than seven years ago are excluded. Verify the current definition under IRC 737(d) and Treas. Reg. 1.737-1(c) at IRS.gov.

How does IRC 737 interact with IRC 704(c)(1)(B)?

IRC 704(c)(1)(B) applies when contributed property is distributed to a non-contributor partner (causing the contributor to recognize gain). IRC 737 applies when the contributor themselves receives other property from the partnership. When both can apply in the same distribution event, IRC 704(c)(1)(B) is analyzed and recognized first. The amount recognized under IRC 704(c)(1)(B) reduces the net precontribution gain pool for IRC 737 purposes, preventing double recognition of the same precontribution appreciation. Verify the ordering rule under Treas. Reg. 1.737-1(a) and Treas. Reg. 1.704-4 at IRS.gov.

What basis adjustments result from IRC 737 gain recognition?

Under IRC 737(c), two parallel adjustments occur: (1) the distributing partner's outside basis in the partnership interest is increased by the gain recognized under IRC 737(a), applied immediately before the distribution reduces outside basis under IRC 733; and (2) the partnership's adjusted basis in the contributed property that generated the net precontribution gain is increased by the same amount. These adjustments eliminate the risk of double taxation: the inside basis increase prevents the partnership from later recognizing the same gain when the contributed property is eventually sold or distributed. Verify the basis adjustment rules under IRC 737(c) and Treas. Reg. 1.737-3 at IRS.gov.

How is the IRC 737 gain characterized -- capital or ordinary?

The character of IRC 737 gain mirrors the character of the net precontribution gain in the contributed property. If the contributed property is a capital asset, the IRC 737 gain is capital. If the contributed property includes ordinary income property (inventory, accounts receivable, depreciable property subject to IRC 1245 or 1250 recapture), the portion of net precontribution gain from ordinary income property is ordinary income under IRC 737. Where the pool mixes capital and ordinary income property, the recognized amount is allocated proportionately between capital and ordinary character. Verify the character rules under Treas. Reg. 1.737-1(d) and IRS.gov.

Does IRC 737 apply when money, rather than property, is distributed?

No. IRC 737 applies only to distributions of property other than money. A cash distribution does not trigger IRC 737 regardless of the partner's net precontribution gain. However, the cash reduces outside basis under IRC 733, which affects the Prong 2 computation in any future property distribution within the seven-year window. Marketable securities may be treated as money under IRC 731(c), potentially removing them from IRC 737 analysis. Verify the marketable security rule and the IRC 731(c) boundary at IRS.gov and in the current Code before classifying any distributed asset.

What is the effect of the seven-year period on IRC 737 planning?

Once seven years have elapsed from a contribution date, that contributed property drops out of the net precontribution gain pool. A property distribution occurring more than seven years after all of a partner's contributions carries no IRC 737 exposure from those contributions. The seven-year window is tracked contribution by contribution -- partial periods apply when some contributions are within seven years and others have aged out. The seven-year period may be tolled or re-started in certain restructuring transactions, so advisors must confirm the applicable dates in any reorganization scenario. Verify the seven-year period and any tolling rules under IRC 737(d) and Treas. Reg. 1.737-2 at IRS.gov.

How does IRC 737 interact with IRC 751 hot assets on a distribution?

IRC 751(b) and IRC 737 apply independently. When a distribution affects a partner's proportionate share of hot assets (unrealized receivables and substantially appreciated inventory), IRC 751(b) recharacterizes part of the transaction as a deemed sale, producing ordinary income. Separately, if the distributing partner has contributed appreciated property within the seven-year window, IRC 737 may also apply. The amounts computed under IRC 751(b) and IRC 737 do not reduce each other. The practitioner must complete the IRC 751(b) analysis first, then independently complete the IRC 737 analysis, and report both amounts on the partner's return. Verify the combined reporting obligations at IRS.gov and in Treas. Reg. 1.751-1(b) and 1.737-1.

The following guides address partnership tax provisions that intersect directly with the IRC 737 analysis.

IRC 704(e): Family Partnership Income Allocation, Bona Fide Capital Interest, and Donee Partner Rules -- the IRC 704(c) contribution rules that underpin IRC 737 also apply in family partnership structures where income allocations and capital interest transfers frequently involve contributed property; the bona fide partner and capital interest tests determine whether IRC 737 exposure even arises in those arrangements.
IRC 707: Disguised Sales and Guaranteed Payments -- when a contribution and distribution are sufficiently related, IRC 707(a)(2)(B) may recharacterize the contribution as a sale rather than a true contribution; if IRC 707 applies, IRC 737 does not, because there is no recognized partnership contribution for IRC 737 to look back on; both provisions must be evaluated at the planning stage.
IRC 708: Partnership Termination and Continuation Rules -- a partnership termination under IRC 708 can reset or accelerate the IRC 737 seven-year look-back; contributed property's seven-year clock and the IRC 704(c) book-tax difference tracking both require attention when a partnership is terminated or restructured within the contribution window.
IRC 752: Partnership Liability Allocation and Outside Basis -- a partner's outside basis (the Prong 2 denominator in the IRC 737 lesser-of test) includes their share of partnership liabilities under IRC 752; changes in liability allocation directly affect outside basis and therefore directly affect IRC 737 exposure; both recourse and nonrecourse liability allocation rules matter here.
IRC 761: Partnership Definition, Exclusion Election, and Form 1065 Reporting -- IRC 737 applies only to arrangements that qualify as partnerships under the Code; understanding the IRC 761 definition and the election-out provisions is a threshold step in any IRC 737 analysis; an arrangement that is not a partnership is not subject to IRC 737 regardless of the property contributed and distributed.
