Section 754 Election: How Partnerships Use Inside Basis Step-Ups to Save Incoming Partners and Heirs From Phantom Gains

A buyer pays $450,000 for a 25% stake in a successful real estate partnership. A few years later, the partnership sells one of its buildings, and that buyer suddenly receives a Schedule K-1 showing $200,000 of taxable gain — gain that economically belongs to the seller who cashed out years earlier. The buyer paid full market price, owes the IRS thousands of dollars in tax, and has nothing to show for it.

This is "phantom gain," and it's one of the most painful — and most preventable — surprises in partnership tax. The fix is a single sentence attached to a Form 1065. It's called a Section 754 election, and any partnership that admits new partners, distributes property, or expects to outlive one of its founders should understand exactly how it works.

The Two-Basis Problem That Section 754 Solves

Every partnership keeps two parallel sets of tax records. Inside basis is the partnership's adjusted basis in its assets — the original cost of the building, the equipment, the inventory, less depreciation. Outside basis is each partner's basis in their partnership interest — what they paid for it, plus or minus their share of income, losses, and contributions over time.

When a partnership starts, inside basis and outside basis usually match. A partner contributes $250,000 cash, the partnership puts that cash into a building, and both numbers line up at $250,000.

But over time, the two figures drift apart. The building appreciates from $1 million to $2 million on the open market, while its inside basis falls because of depreciation. A new partner buying in pays for current fair value. An heir inherits at the date-of-death value. Suddenly, the inside basis the partnership tracks for that partner's share is far below what they paid or inherited.

Section 754 of the Internal Revenue Code is the bridge. It lets a partnership adjust its inside basis when one of two events occurs: a transfer of a partnership interest (Section 743(b)) or a distribution of partnership property (Section 734(b)). Without the election, the inside-outside gap simply sits there — until it shows up as phantom gain on someone's K-1.

When the Election Matters: Two Triggers

Trigger 1: A Transfer of a Partnership Interest (Section 743(b))

This is the most common trigger. It applies when:

• A partner sells their interest to a new partner.
• A partner exchanges their interest in a non-tax-free transaction.
• A partner dies and their interest passes to an heir or estate.

In each case, the new owner usually has an outside basis that differs sharply from their share of the partnership's inside basis. Section 743(b) adjusts the inside basis of partnership assets — but only with respect to the transferee partner. The other partners' shares of inside basis don't change.

Trigger 2: A Distribution of Partnership Property (Section 734(b))

This trigger fires when the partnership distributes cash or property to a partner in a way that causes a mismatch. For example:

• A retiring partner receives cash that exceeds their outside basis.
• A partnership distributes appreciated property and the receiving partner takes it at carryover basis.
• A liquidating distribution leaves the remaining inside basis out of sync with the outside bases of the continuing partners.

Section 734(b) adjusts inside basis at the partnership level — affecting all remaining partners — to keep things balanced going forward.

A single Section 754 election covers both Section 743(b) and Section 734(b). You don't elect them separately.

The Phantom Gain Trap, Walked Through

Imagine a four-partner real estate partnership. Each partner has a $250,000 capital account, and the partnership owns a single building purchased years ago for $1 million with $1 million of inside basis remaining (assume no depreciation for simplicity). The building is now worth $1.8 million.

Partner B wants out. Partner A buys Partner B's 25% interest for $450,000 — Partner B's share of the $1.8 million fair market value.

Without a Section 754 election, here's what happens:

• Partner A's outside basis: $450,000 (what they paid).
• Partner A's share of inside basis: $250,000 (their share of the partnership's $1 million inside basis).

A year later, the partnership sells the building for $1.8 million. The partnership recognizes $800,000 of gain ($1.8M sale price minus $1M inside basis), and Partner A is allocated 25% — $200,000 of taxable gain.

But Partner A already paid $200,000 over their share of inside basis when they bought in. They're now being taxed on appreciation that the seller (Partner B) had baked into the purchase price. Partner A pays tax twice in economic substance: once through a higher purchase price, and again through a K-1 allocation.

With a Section 754 election in place, Section 743(b) creates a $200,000 basis adjustment specific to Partner A. When the partnership sells the building, the gain allocated to Partner A drops to zero. The other three partners still recognize their share of gain — as they should, because they actually benefit from the sale.

The Death-of-a-Partner Scenario

Section 754 is just as critical when a partner dies. Federal estate tax rules give heirs a stepped-up basis to fair market value on the date of death (Section 1014). But that step-up applies only to the outside basis of the partnership interest. The inside basis of the partnership's assets is untouched unless the partnership makes a 754 election.

Take a partnership that owns real estate originally purchased for $500,000, now worth $2 million. Partner A held a 25% interest and dies. The heir inherits at fair market value: outside basis of $500,000 (25% of $2 million). The heir's share of inside basis is still only $125,000 (25% of $500,000).

If the partnership later sells the property — or simply allocates depreciation deductions — the heir is on the hook for $375,000 of gain that occurred during the original partner's lifetime. Estate tax was already paid on that appreciation. Income tax on top of it is double taxation in economic substance.

A Section 754 election creates a Section 743(b) adjustment specific to the heir, stepping up their share of inside basis from $125,000 to $500,000. The result: higher depreciation deductions immediately, and no phantom gain when the property is eventually sold.

This is why estate planners often refer to the 754 election as one of the most overlooked planning opportunities for partners in real estate, professional services, and family businesses.

How to Make the Election

The mechanics are surprisingly simple. The partnership attaches a written statement to its timely filed Form 1065 (including extensions) for the tax year in which a triggering event occurs. The statement must contain:

1. The name and address of the partnership.
2. A declaration that the partnership elects under Section 754 to apply Sections 734(b) and 743(b).

That's it. No fee, no advance approval, no special form for the election itself.

But the actual basis adjustments are not simple. Computing a 743(b) adjustment requires:

• Determining the transferee's outside basis (purchase price, fair market value at death, or whatever applies).
• Calculating the transferee's share of the partnership's inside basis at the time of transfer.
• The difference is the total Section 743(b) adjustment.
• That adjustment is then allocated across partnership assets under Section 755 — the rules that govern how the step-up is spread among different asset classes, generally by reference to fair market value within capital and ordinary income asset categories.

For partnerships with significant Section 1245 property, depreciable real estate, and intangibles, the Section 755 allocation is intricate enough that most practitioners run it through specialized software or an experienced CPA.

The Permanence Problem

Section 754 is a one-way door. Once made, the election applies to every future transfer and distribution — forever — unless and until the IRS grants a revocation. To revoke, the partnership must file Form 15254 and demonstrate sufficient cause.

The IRS has a published list of acceptable reasons for revocation:

• A change in the nature of the partnership's business.
• A substantial increase in the partnership's assets.
• A change in the character of partnership assets.
• An increased frequency of transfers.

Importantly, the IRS will not approve a revocation when the primary purpose is to avoid a basis reduction. If your partnership has appreciated assets, you cannot turn the election off just because a new transfer would produce an unfavorable downward adjustment.

This permanence cuts both ways. The election is wonderful when assets have appreciated and a new partner buys in or an heir inherits. It's painful when assets have declined and a transfer triggers a reduction in inside basis under Section 743(b).

When the Election Becomes Mandatory Anyway

There's one scenario where you don't get to choose. Under the substantial-built-in-loss rules (Section 743(d)), a Section 743(b) basis adjustment is mandatory — even without a Section 754 election — when:

1. There's a transfer of a partnership interest, and
2. The partnership's adjusted basis in its assets exceeds the fair market value by more than $250,000, or
3. The transferee partner would be allocated a loss greater than $250,000 if the partnership disposed of all its assets in a fully taxable transaction immediately after the transfer.

The purpose is to prevent a double benefit on built-in losses. The selling partner already gets to recognize their loss; without the mandatory adjustment, the buyer would inherit a duplicate loss baked into the partnership's high asset basis.

Mandatory 734(b) adjustments work similarly for distributions that would otherwise create a "substantial basis reduction" — generally a $250,000 threshold downward adjustment.

If your partnership might be subject to these mandatory rules, the practical consequence is that you're already living with downside basis adjustments. Making a formal Section 754 election to also capture upside step-ups often becomes a no-brainer.

When You Should Make the Election

Strong candidates for a Section 754 election include:

• Real estate partnerships holding appreciating buildings. The depreciation pickup for incoming partners can be substantial.
• Family partnerships holding assets likely to be inherited. The 754 election is often the difference between a smooth generational transfer and an avoidable income tax bill.
• Professional service partnerships (law firms, medical practices) with goodwill, client lists, or other intangibles where partners regularly come and go.
• Operating businesses in stable or appreciating industries where partner departures are common.

Strong candidates to defer or skip the election include:

• Partnerships holding assets that may decline in value, where a future transfer could trigger an unwelcome downward 743(b) adjustment.
• Partnerships likely to dissolve before any transfer occurs.
• Very small or short-lived partnerships where the administrative complexity outweighs the benefit.
• Partnerships in volatile asset classes where you'd prefer to wait for the right moment.

Remember: you can wait to make the election until the year a triggering event actually occurs. There's no penalty for not having one in place ahead of time, as long as your accountant has time to file the election with that year's return.

The Recordkeeping Burden

This is where good financial discipline pays off. Once a partnership makes a Section 754 election:

• Each transferee partner has their own personal Section 743(b) adjustment that travels with them.
• That adjustment is allocated across multiple partnership assets under Section 755.
• The partnership must track separate depreciation schedules — one set for the partnership as a whole, plus a personal layer for each partner with a 743(b) adjustment.
• When a 743(b) partner sells assets, transfers their interest, or dies, the calculations cascade.

Multiply this across a partnership with five, ten, or fifty transferee adjustments stacked over the years, and the accounting layer becomes substantial. This is why having clean, traceable financial records — partner by partner, asset by asset — is so critical. Spreadsheets fail at this scale; even mainstream accounting software often hides too much. Plain-text accounting systems that let you tag, trace, and audit every entry at the partner-asset level become invaluable when an IRS examiner asks where a particular adjustment came from in 2031.

Three Common Mistakes

1. Missing the deadline. The 754 election must be attached to a timely filed return for the year of the triggering event. Late returns lose the election for that year. Some partnerships have obtained Section 9100 relief (a regulatory remedy for missed elections), but it requires showing reasonable cause and acting in good faith — not a guarantee.

2. Forgetting that the election is permanent. Partnerships make a 754 election to capture a single beneficial step-up, then realize years later that the same election now creates ongoing administrative work or a forced downward adjustment they didn't want. Plan for the long term, not just the next K-1.

3. Failing to allocate the 743(b) adjustment correctly. The Section 755 allocation rules determine which assets receive the basis bump. A partnership that allocates the entire adjustment to land (because land is the easy answer) loses the depreciation benefit they should have allocated to depreciable buildings. This is expensive over a long holding period.

Coordination With Other Tax Rules

A Section 754 election doesn't operate in a vacuum. Common interactions to watch:

• Section 704(c) — built-in gain/loss on contributed property. The 743(b) adjustment is computed after the transferee's share of any 704(c) layer is taken into account.
• Section 1245 / 1250 recapture — depreciation recapture rules apply to the post-754 basis layer just as they do to original basis.
• Section 199A — the qualified business income deduction for pass-through owners can interact with depreciation deductions generated by 743(b) adjustments.
• State tax conformity — most states follow the federal Section 754 election automatically, but a few (notably California in some scenarios) have their own quirks.

Don't make a 754 election without modeling its interaction with at least 704(c), depreciation recapture, and your state's pass-through entity tax regime.

Keep Your Partnership Books Audit-Ready From Day One

Partnership tax accounting — especially with active 754 adjustments — punishes sloppy recordkeeping. Each partner's 743(b) layer, each asset's allocated step-up, and each year's depreciation calculation needs to be traceable years later, often by a successor accountant or a tax examiner. Beancount.io provides plain-text accounting that gives you complete transparency and version-controlled history over every entry — a natural fit for partnerships that need to prove how every adjustment was computed.
