Section 754 Election: The Step-Up Most Partnership Buyers Never Hear About

Every partnership runs on two layers of basis. Inside basis is the partnership's own tax basis in its assets: the buildings, equipment, and securities it holds. Outside basis is each partner's basis in their partnership interest, the thing they could sell. At formation the two match: put in $100,000 of cash, your outside basis is $100,000, and your share of inside basis is $100,000 too.

The layers drift apart the moment an interest trades hands. Say a partnership bought a building years ago and the building has appreciated. A new investor buys a partner's 25% interest at today's value. The buyer's outside basis is what they paid, full freight. But the partnership's inside basis in the building did not move; the entity did not buy or sell anything. The buyer now owns a share of assets whose tax basis reflects the seller's history, not the buyer's check. All examples on this page use hypothetical, illustrative round numbers.

Why does the gap matter? Two ways. First, depreciation: the buyer's share of deductions is computed on the partnership's old, largely depreciated basis, not on the price the buyer just paid. Second, gain: when the partnership sells the building, the buyer is allocated a share of gain measured against that old basis, which includes appreciation the buyer already paid the seller for. The tax system eventually squares this up through outside basis when the buyer exits, but "eventually" can be a decade away, and a deduction today is worth more than the same deduction at liquidation. Section 754 exists to close the gap now instead of later.

A single 754 election switches on two separate adjustment regimes, and people conflate them constantly. The 743(b) adjustment fires when a partnership interest is transferred: someone buys an interest, exchanges for one, or inherits one at death. It measures the difference between the incoming partner's outside basis and their share of inside basis, and it belongs to that partner alone. Nobody else's depreciation or gain changes. Think of it as a private side ledger the partnership keeps just for the new partner.

The 734(b) adjustment fires on distributions: when the partnership distributes cash or property and the distributee recognizes gain or loss, or the distributed property's basis changes in their hands. Unlike 743(b), this adjustment goes onto the partnership's common books and affects all remaining partners. It exists so a distribution that shifts basis out of the partnership does not permanently distort what is left behind.

For most investors reading this page, the 743(b) side is the one that matters: you bought or inherited an interest and want the basis you paid for. The rest of this page leans that way, with 734(b) reappearing in the mandatory-adjustment rules and the downsides.

Notice who benefits: the buyer, entirely. The seller's tax on selling the interest is identical either way, and the other partners are untouched because 743(b) is partner-specific. This asymmetry is why the election belongs on the buyer's due diligence checklist, not the seller's. If the partnership has never made the election, the buyer should make the closing conditional on it, because after the wire clears the leverage is gone.

Death works the same mechanical way as a purchase, with the estate rules supplying the price. When a partner dies, the heir's outside basis in the partnership interest generally resets to fair market value at the date of death under Section 1014. That step-up happens automatically. What does not happen automatically is anything inside the partnership: the entity's basis in its buildings and equipment is exactly what it was the day before.

One planning note we flag for married clients: in community property states, the death of one spouse can adjust the basis of the entire community interest, not just the decedent's half, which can make the 754 election dramatically more valuable at the first death. The rules depend on how the interest is titled and on state property law, so this is a conversation to have with your CPA and estate attorney together, before the estate's first partnership return is filed.

Everything above described a voluntary regime: no election, no adjustment. There are two exceptions, both aimed at losses, and both apply whether or not anyone elected anything.

First, transfers with a substantial built-in loss. If a partnership's assets are worth meaningfully less than their inside basis when an interest is transferred, the partnership must adjust basis downward for the transferee as if a 754 election were in place. The statute defines "substantial" with specific dollar thresholds, tested at both the partnership level and, under post-2017 law, at the transferee level; we verify the current figures on every engagement rather than reciting them here. The purpose is blunt: without the rule, a built-in loss could be deducted once by the seller (through their sale loss) and again by the buyer (through the partnership), and Congress decided one deduction per loss is plenty.

Second, distributions causing a substantial basis reduction. The mirror-image rule on the 734(b) side: if a distribution would shift enough basis out of the partnership, measured against another statutory dollar threshold, the partnership must reduce the basis of its remaining assets even without an election. Same anti-duplication logic, distribution flavor.

Mechanically, the election is almost anticlimactic. The partnership attaches a written statement to a timely filed return, including extensions, for the tax year in which the transfer or distribution occurred. The statement identifies the partnership and declares that it elects under Section 754 to apply the basis adjustment provisions. Under the current regulations the statement no longer requires a partner's signature, which eliminated a whole genre of foot-fault where an otherwise valid election failed for a missing signature. Older guides still mention the signature requirement; it is gone.

Three features of the election deserve more respect than the one-page statement suggests. It is sticky: once made, it applies to that year and every year after, covering all future qualifying transfers and distributions, including ones where the adjustment runs against you. It is hard to undo: revocation requires an application to the IRS and consent, granted for sufficient reason, not on request. And it is deadline-driven:miss the return for the year of the event and you are into late-election relief territory, which is discretionary, slower, and more expensive than filing one page on time.

The practical answer to "when to make a 754 election" is therefore: decide in the year something happens. An interest sold, a partner died, a redemption distribution went out; that year's return is the window. Partnerships with no transfers pending have no reason to elect prophylactically, and good reasons not to, covered in section eight.

Section 754 shows up in every corner of partnership tax, but real estate is where the dollars get large, for one reason: buildings are big, appreciating, depreciable assets. The slice of a 743(b) adjustment allocated to depreciable real property is generally treated as newly placed in service, meaning the buyer starts a fresh recovery period on their private basis layer. That fresh start is what turns the election from a bookkeeping nicety into an income stream.

It also stacks with cost segregation. The Section 755 allocation follows where the value sits, and a cost segregation analysis of the underlying property can support pushing part of the adjustment onto shorter-lived components, 5-year and 15-year property, instead of parking everything on the 27.5-year or 39-year building. Same adjustment, faster deductions. Sponsors who commission cost seg studies at acquisition already have most of the data this analysis needs.

The sharpest edge: bonus depreciation. Under the current regulations, a 743(b) adjustment from an arm's-length purchase of a partnership interest can qualify for bonus depreciation on the portion allocated to qualifying short-lived property, under the used-property acquisition rules, where the buyer had no prior use of the assets and is unrelated to the seller. Adjustments at death and 734(b) adjustments generally do not qualify. This is one of the most commonly botched areas of the entire regime, in both directions, and it is exactly the kind of claim to have verified against the current regulations for your facts rather than taken from a web page, including this one.

For syndication investors, this all lands in one increasingly common scenario: buying a secondary LP interest. Funds and marketplaces now trade LP positions in real estate syndications mid-life, after the original cost segregation and bonus depreciation are spent. A secondary buyer without a 754 election steps into a depreciation-exhausted position at full price: distributions with no shelter, then a gain allocation that includes the original investors' appreciation. With the election, the buyer's 743(b) adjustment rebuilds their own depreciation base. Ask whether the election is in effect before pricing the interest, because the after-tax return difference between the two answers is not small. And remember the deductions the adjustment creates are still passive for a limited partner; the passive activity loss rules decide when you can actually use them.

Most content about Section 754 reads like a sales page for it. The election is often right, but it is a permanent commitment with real costs, and there are partnerships that rationally decline it.

The administrative burden is real and does not expire. Every 743(b) adjustment is a partner-specific basis layer the partnership must carry: separate depreciation schedules, separate gain calculations on every asset sale, separate K-1 reporting, for each affected partner, every year, until the assets are gone or the partner leaves. A partnership with steady turnover, think a fund admitting and redeeming investors regularly, can end up maintaining dozens of parallel basis ledgers. That is a permanent line item in the accounting budget, and preparers price it accordingly.

The election cuts both ways. Once in effect it applies to every future qualifying event, including transfers when values have fallen. An interest that changes hands below its share of inside basis produces a negative adjustment: less depreciation and more gain for the incoming partner, mandatorily, because the election cannot be switched off for the bad years. A partnership that elects at the top of a market has signed its future buyers up for whatever the market does next. (And past a statutory threshold, downward adjustments are required even without the election, as covered in section five.)

Small partnerships can be underwater on cost alone. If the step-up is $30,000 allocated to a 27.5-year asset, the annual benefit is about $1,100 of depreciation, worth a few hundred dollars of tax. If maintaining the adjustment adds a comparable amount to the annual preparation bill, the election is a wash or worse. The math that justifies a $700,000 estate step-up does not automatically justify a small one. Run the numbers: size of adjustment, how much lands on depreciable property, the partners' tax rates, and the incremental accounting cost, before filing a statement you cannot easily unfile.

The election leaves fingerprints. The partnership's Form 1065 answers direct questions about whether a 754 election is in effect and whether 743(b) or 734(b) adjustments were made during the year. On your Schedule K-1, partner-specific 743(b) items show up as separately stated adjustments, income or deduction lines tied to your private basis layer, with supporting detail in the attached statements. If you bought an interest last year, paid well above your share of inside basis, and your K-1 shows no adjustment anywhere, that is not proof something is wrong, but it is exactly the question to ask the preparer in writing.

Before buying any partnership interest, or signing off on an estate that holds one, get answers to five questions:

None of these questions are hostile, and a competent sponsor or preparer can answer all five in a day. Hesitation on question four is the most informative answer you can get: it tells you the partnership's basis records, the thing your future deductions depend on, are not actually being kept.
