Section 704(c) gain or loss in a partnership is the built-in gain or loss that exists when a partner contributes property whose fair market value differs from its tax basis, and the rule requires the partnership to allocate that pre-contribution gain or loss back to the contributing partner rather than spreading it across everyone.1Office of the Law Revision Counsel. 26 USC 704 – Partners Distributive Share The mechanics get technical fast, but the goal is simple: keep the tax consequences of appreciation or decline that happened before contribution tied to the partner who actually experienced it.
What Built-In Gain or Loss Is
Built-in gain or loss is the gap between a contributed property’s fair market value and the contributing partner’s tax basis at the moment of contribution. Value above basis is built-in gain. Basis above value is built-in loss. That gap is fixed on the contribution date, and the partnership tracks it until depreciation, amortization, or a sale eliminates it.
A running example makes the mechanics concrete. Partner A contributes equipment worth $50,000 with a tax basis of $20,000, creating a $30,000 built-in gain. Partner B contributes $50,000 cash. Each partner’s book capital account shows $50,000, but the equipment’s tax basis inside the partnership stays at $20,000. That $30,000 book-tax gap is what Section 704(c) exists to police.
From that point forward the partnership keeps two sets of numbers for the equipment. Book value starts at $50,000; tax basis starts at $20,000. Book depreciation runs off the higher number, tax depreciation off the lower one, and the divergence between them is where the allocation work happens.
The Three Allocation Methods
Treasury Regulation 1.704-3 lays out three methods a partnership can use to satisfy Section 704(c): traditional, curative, and remedial.2eCFR. 26 CFR 1.704-3 – Contributed Property All three are presumed reasonable. They differ in how aggressively they close the book-tax gap.
Traditional Method
The traditional method is the default and the simplest. Allocate tax items to the non-contributing partner to match that partner’s book allocation, to the extent the partnership actually has tax items to allocate. When tax depreciation falls short of book depreciation, the shortfall stays with the contributing partner.
Continuing the example: assume the equipment has a five-year life. Annual book depreciation is $10,000, split $5,000 to each partner. Annual tax depreciation is only $4,000 because tax basis is $20,000. Under the traditional method, all $4,000 of tax depreciation goes to Partner B. Partner A gets nothing. Partner B is still $1,000 short of their $5,000 book allocation, and that shortfall reflects the ceiling rule.
The Ceiling Rule
The ceiling rule caps total tax allocations for a property at the partnership’s actual tax gain, loss, or deduction for that property. The partnership cannot allocate tax items it doesn’t have. When built-in gain is large relative to remaining tax basis, the ceiling rule can leave the non-contributing partner substantially undercompensated on the tax side, receiving book deductions the tax return will never match. That distortion is why the two other methods exist.
Curative Method
The curative method fixes ceiling-rule shortfalls by reallocating other existing partnership tax items to the shorted partner. Nothing gets invented. The partnership simply shifts real deductions or losses from other sources toward the partner who came up short.
If the equipment shortfall left Partner B $1,000 short each year, and the partnership also had, say, interest expense that would normally split evenly, the partnership could allocate an extra $1,000 of that interest to Partner B and reduce Partner A’s share by the same amount. Curative allocations cannot exceed what’s needed to close the gap, must be applied consistently year to year, and should generally match the character of the shortfall (a depreciation shortage cured with other deductions or losses, not with income shifts). The obvious limit: the partnership needs other tax items available. If the contributed property is the only meaningful source of deductions, there is nothing to reallocate.
Remedial Method
The remedial method eliminates ceiling-rule distortions by creating hypothetical tax items. Where curing requires existing items, remedial manufactures offsetting entries that exist only for allocation purposes.
When Partner B is short, the partnership creates a hypothetical tax deduction equal to the shortfall and allocates it to Partner B, and simultaneously creates an offsetting hypothetical income item and allocates it to Partner A. The two entries cancel at the partnership level, so total taxable income is unchanged, but each partner’s individual tax picture reflects what economic reality demands. The character of the remedial income must match the character of the deduction it offsets.
The remedial method also changes how book depreciation is computed. The book basis splits into two layers: the portion equal to the property’s tax basis at contribution is recovered using the same method and period as tax depreciation, and the remaining book basis is recovered as if the partnership had just purchased a new asset of that type on the contribution date.
Choosing and Applying a Method
Section 704(c) applies property by property. Contributed assets cannot be lumped together and netted against each other. Each property carries its own built-in amount, its own tracking, and its own method.
A partnership can use different methods for different properties, but once a method is chosen for a given asset, that method sticks with that asset. Switching mid-stream on the same property is not allowed. And the overall combination has to be reasonable in light of Section 704(c)’s purpose. The regulations flag some patterns as suspect: using one method for appreciated property and another for depreciated property, or picking methods in ways that appear designed to funnel tax benefits toward particular partners rather than prevent shifting. An allocation method is not unreasonable just because a different method would produce more total tax, but a pattern suggesting strategic selection will draw scrutiny.
The Small Disparity Exception
Not every contribution triggers full 704(c) tracking. A disparity qualifies as small when both of these are true: the total book value of all property contributed by one partner during the tax year differs from adjusted tax basis by no more than 15 percent of that basis, and the total gross disparity is $20,000 or less.2eCFR. 26 CFR 1.704-3 – Contributed Property When both tests are met, the partnership can use any reasonable method, ignore 704(c) for that property, or defer the allocation until disposition. For partnerships with lots of small contributions, that exception saves real recordkeeping effort.
Built-In Loss Property
When contributed property has a tax basis exceeding its fair market value, Section 704(c)(1)(C) restricts how the excess basis can be used. The built-in loss counts only for allocations to the contributing partner. For every other partner, the partnership treats the property’s basis as equal to its fair market value at contribution.1Office of the Law Revision Counsel. 26 USC 704 – Partners Distributive Share
Suppose a partner contributes land with a basis of $80,000 and a fair market value of $50,000. If the partnership later sells the land at a loss, the other partners compute their share against the $50,000 figure, not the $80,000 basis. The extra $30,000 of loss stays with the contributor. The rule prevents partners from contributing loss property and spreading the tax benefit to others who didn’t bear the economic decline.
Character of Gain or Loss on Contributed Property
Section 704(c) governs how much gain or loss goes to each partner. Section 724 governs what kind of gain or loss it is. Certain characteristics carry over from the contributing partner’s hands.3Office of the Law Revision Counsel. 26 USC 724 – Character of Gain or Loss on Contributed Unrealized Receivables, Inventory Items, and Capital Loss Property
- Unrealized receivables produce ordinary income or loss on disposition, with no time limit.
- Inventory items in the contributor’s hands produce ordinary gain or loss if disposed of within five years of contribution.
- Capital loss property produces capital loss (up to the built-in loss at contribution) if the loss is recognized within five years.
These rules keep partners from converting ordinary items into capital gains by moving them through a partnership. The five-year windows for inventory and capital loss property eventually close; the receivables rule never does.
Sale and Distribution of 704(c) Property
When the partnership sells contributed property, any remaining built-in gain or loss is allocated entirely to the contributing partner. The non-contributing partner is allocated tax gain equal to their book gain, and the contributor absorbs the rest.
Two seven-year rules also apply. Under Section 704(c)(1)(B), if the partnership distributes contributed property to any partner other than the contributor within seven years of contribution, the contributor recognizes gain or loss as if the property had been sold at fair market value on the distribution date. Character is determined by reference to how a partnership sale to the distributee would have been characterized, and the contributor’s basis in their partnership interest is adjusted for the recognized amount.1Office of the Law Revision Counsel. 26 USC 704 – Partners Distributive Share
Section 737 addresses the mirror situation. When the contributing partner receives a distribution of other property within seven years of their contribution, that partner recognizes gain equal to the lesser of two amounts: the excess of the distributed property’s fair market value over the partner’s adjusted basis in the partnership interest (reduced by any cash in the distribution), or the partner’s net precontribution gain. Net precontribution gain measures how much of the built-in gain from that partner’s contributed assets is still sitting inside the partnership. Section 737 targets partners who contribute appreciated property and then extract value through distributions of different property, effectively cashing out appreciation without triggering the 704(c) gain. Getting back the same property the partner originally contributed does not count.4Office of the Law Revision Counsel. 26 USC 737 – Recognition of Precontribution Gain in Case of Certain Distributions to Contributing Partner
Recordkeeping That Actually Works
The partnership has to keep records sufficient to identify each contributed property’s built-in gain or loss, the allocation method chosen, and how the allocation is computed each year. The partnership agreement typically specifies which method applies, and the method should be documented before the first return reflecting the property is filed.
Complex 704(c) tracking, particularly under the remedial method with its two-layer book depreciation, usually requires specialized software or an experienced preparer. When a partnership holds multiple contributed properties from different partners, each on its own method with its own remaining built-in amount, the calculations compound. Errors cascade. A misallocation in year one distorts every subsequent capital account, and the mismatch often does not surface until an audit or a partner’s exit. Building the tracking correctly at the start costs far less than reconstructing it later.
