7.2 Optional Basis Adjustments (Section 754, 743(b) & 734(b))

Optional Basis Adjustments (Section 754, 743(b) & 734(b))

In partnership taxation, the general rule under IRC §743(a) is that the basis of partnership property is not adjusted as the result of a transfer of an interest in a partnership by sale or exchange or on the death of a partner. Similarly, under IRC §734(a), the basis of partnership property is not adjusted as the result of a distribution of property to a partner.

This default regime creates profound tax distortions between a partner's outside basis and the partnership's aggregate inside basis. For example, if an investor purchases a partnership interest for $100,000 when the underlying assets have a zero basis, a subsequent sale of those assets by the partnership triggers taxable gain to the new purchaser, resulting in double taxation until the partnership liquidates. To resolve this structural problem, Congress enacted IRC §754, authorizing partnerships to elect optional basis adjustments under Section 743(b) (for transfers) and Section 734(b) (for distributions).

The Section 754 Election Mechanics

An IRC §754 election is not an automatic right; it must be formally executed by the partnership.

Making the Election (Treas. Reg. §1.754-1(b))

• Filing Method: The election is made by attaching a written statement to a timely filed Form 1065 (including valid automatic extensions via Form 7004) for the taxable year in which the transfer or distribution occurs.
• Statement Requirements: The statement must declare that the partnership elects under Section 754 to apply the provisions of Section 743(b) and Section 734(b), and must be signed by any partner authorized to sign the partnership return.
• Late Election Relief: If the partnership fails to make a timely election, administrative relief may be requested under Treas. Reg. §301.9100-2 (automatic 12-month relief for regulatory elections) or §301.9100-3.

Irrevocability of the Election

Once made, the Section 754 election applies to all future taxable years and applies to both transfers under §743(b) and distributions under §734(b). The partnership cannot choose one without the other.

• Revoking the Election: An election can be revoked only with the approval of the IRS District Director (filed on Form 15254, Application for Revocation of Election on Section 754).
• Acceptable Grounds for Revocation: Change in the nature of the partnership's business, substantial increase in the volume of assets, change in the character of assets, or increased administrative burden.
• Unacceptable Grounds: The IRS will never permit revocation if the primary purpose is to avoid a downward (negative) basis adjustment on depreciated assets.

Section 743(b) Transferee Basis Adjustments

When a Section 754 election is in effect, IRC §743(b) mandates an adjustment to the basis of partnership property upon:

1. A sale or exchange of a partnership interest; or
2. The transfer of a partnership interest upon the death of a partner (where outside basis steps up or down to date-of-death fair market value under IRC §1014).

Formula for Section 743(b) Adjustment

$\text{Section 743(b) Adjustment} = \text{Transferee's Outside Basis} - \text{Transferee's Share of Partnership Inside Basis}$

• Positive Adjustment (+): If outside basis exceeds the transferee's share of inside basis (stepping up asset basis).
• Negative Adjustment (-): If outside basis is less than the transferee's share of inside basis (stepping down asset basis).

Transferee's Share of Inside Basis (Treas. Reg. §1.743-1(d))

The transferee's share of inside basis is equal to the transferee's interest in the partnership's previously taxed capital, plus the transferee's share of partnership liabilities. Previously taxed capital is the amount of cash the transferee would receive upon a hypothetical complete liquidation of the partnership at fair market value, minus any tax gain (or plus any tax loss) that would be allocated to the transferee on that sale.

Strictly Personal to the Transferee

A critical exam concept: The Section 743(b) adjustment is strictly personal to the transferee partner. It is not reflected in the partnership's common inside basis, does not adjust the capital accounts of the partnership under Section 704(b), and provides no tax benefit or detriment to any other partner. The adjustment is tracked as a personal special basis adjustment and reported on the transferee's Schedule K-1.

Depreciation of Positive §743(b) Adjustments

Under Treas. Reg. §1.167(c)-1(a)(6), if the Section 743(b) adjustment increases the basis of depreciable property, the positive adjustment is treated as newly purchased property placed in service on the date of transfer. It is depreciated over a fresh recovery period using any permissible depreciation method (e.g., straight-line over 27.5 years for residential rental property or 39 years for commercial property).

Section 755 Allocation of Basis Adjustments

Once the gross Section 743(b) adjustment is determined, IRC §755 governs how the adjustment is allocated among specific partnership assets through a strict two-step process:

Gross §743(b) Adjustment
  ├── Class 1: Capital Assets & Section 1231 Property
  └── Class 2: Ordinary Income Property (Inventory, Receivables, §1245 Recapture)

Step 1: Allocation Between the Two Statutory Classes

Under Treas. Reg. §1.755-1(b)(2), the gross adjustment is allocated between Class 1 and Class 2 based on the net gain or loss that would be allocated to the transferee from a hypothetical sale of each class at fair market value.

Step 2: Allocation to Specific Assets Within Each Class

Within each class, the adjustment is allocated to individual assets based on the amount of hypothetical gain or loss allocable to the transferee from the hypothetical sale of each individual asset. Under modern regulations (Treas. Reg. §1.755-1), positive adjustments can be allocated to appreciated assets even while negative adjustments are simultaneously allocated to depreciated assets within the same class.

Mandatory Section 743(d) Basis Adjustments (Substantial Built-in Loss)

Historically, partnerships without a Section 754 election could avoid downward basis adjustments when selling interests in depreciated partnerships. To shut down this abuse, Congress enacted IRC §743(d):

Definition of Substantial Built-in Loss

A partnership has a substantial built-in loss if:

1. Entity-Level Test: The partnership's adjusted tax basis in its property exceeds the fair market value of such property by more than $250,000; OR
2. Transferee Allocation Test (enacted by TCJA): The transferee partner would be allocated a net loss of more than $250,000 upon a hypothetical liquidation sale of all partnership assets at fair market value immediately after the transfer.

If either test is satisfied, the downward basis adjustment is mandatory, applying strictly to the transferee partner.

Section 734(b) Basis Adjustments on Distributions

While Section 743(b) adjusts basis for transfers, IRC §734(b) adjusts the partnership's common inside basis in remaining assets when distributions occur.

When Does a Positive (+) Section 734(b) Adjustment Occur?

A partnership increases the adjusted basis of remaining partnership property by:

1. Gain Recognized by Distributee: The amount of any taxable gain recognized by the distributee partner under IRC §731(a)(1) (when cash distributed exceeds outside basis); and
2. Basis Step-Down in Distributed Property: The amount by which the partnership's adjusted inside basis in the distributed property immediately prior to distribution exceeds the basis the distributee takes in that property under IRC §732(a)(2) (in a nonliquidating distribution limited by outside basis) or IRC §732(b).

When Does a Negative (-) Section 734(b) Adjustment Occur?

A partnership decreases the adjusted basis of remaining partnership property by:

1. Loss Recognized by Distributee: The amount of any loss recognized by the distributee partner under IRC §731(a)(2) upon complete liquidation (applicable only when a liquidating distribution consists solely of money, unrealized receivables, and inventory); and
2. Basis Step-Up in Distributed Property: The amount by which the distributee's basis in the distributed property under IRC §732(b) exceeds the partnership's pre-distribution inside basis in that property.

Unlike §743(b), a Section 734(b) adjustment is an entity-level common basis adjustment that benefits or burdens all remaining partners in accordance with their capital and profits ratios.

Mandatory Section 734(d) Adjustment (Substantial Basis Reduction)

Under IRC §734(d), a downward Section 734(b) adjustment is mandatory (even with no §754 election) if the distribution results in a substantial basis reduction—defined as a downward basis adjustment exceeding $250,000.

Comprehensive Worked Example: Section 743(b) Calculation

Facts: Pioneer Partnership has three equal partners (A, B, and C). The partnership has a valid Section 754 election in effect. Partner A sells her 1/3 partnership interest to Buyer D for $150,000 cash. Pioneer has no liabilities. The partnership's sole assets are:

• Cash: $60,000 (Basis $60,000)
• Capital Asset X: Basis $90,000; FMV $180,000 (Unrealized gain $90,000)
• Capital Asset Y: Basis $150,000; FMV $210,000 (Unrealized gain $60,000)
• Total Assets: Basis $300,000; FMV $450,000

Step 1: Compute Transferee's Outside Basis

• Buyer D's purchase price: $150,000.

Step 2: Compute Transferee's Share of Inside Basis

• Total entity inside basis is $300,000. D's 1/3 share: 1/3 × $300,000 = $100,000.

Step 3: Compute Gross Section 743(b) Adjustment

• Adjustment: $150,000 (outside basis) - $100,000 (share of inside basis) = +$50,000.

Step 4: Allocate Adjustment under Section 755

• Both assets are capital assets. The $50,000 adjustment is allocated based on D's allocable share of hypothetical gain in each asset:
  • Capital Asset X: D's 1/3 share of gain is 1/3 × $90,000 = $30,000. Asset X receives a +$30,000 basis adjustment.
  • Capital Asset Y: D's 1/3 share of gain is 1/3 × $60,000 = $20,000. Asset Y receives a +$20,000 basis adjustment.
  • Check total: $30,000 + $20,000 = $50,000.

Tax Result upon Subsequent Sale: If Pioneer subsequently sells Capital Asset X for $180,000:

• Entity tax gain: $180,000 - $90,000 = $90,000.
• Partners B and C each report 1/3 × $90,000 = $30,000 gain.
• Partner D is allocated $30,000 gain, which is completely offset by D's personal $30,000 §743(b) basis adjustment, resulting in $0 recognized gain to Partner D!
