A partner in your LLC dies holding an interest with a tax basis of $100,000 and a fair market value of $1,000,000. Her heirs inherit the interest with a stepped-up outside basis equal to that $1,000,000 fair market value — the classic Section 1014 step-up. So far, so good.
Now the partnership sells one of its appreciated buildings the following year. The heirs get a Schedule K-1 allocating them their share of the gain, taxed at capital gains rates plus depreciation recapture, on the full appreciation that built up while their mother was still alive. That estate-tax step-up they thought they got? Worthless inside the partnership.
That outcome — paying tax twice on the same economic appreciation — is exactly what the Section 754 election was designed to prevent. Yet partnerships routinely miss it, miss the deadline, or make it without understanding the long-term administrative cost. This guide walks through the mechanics of Section 754, the Section 743(b) adjustment on partner transfers, the Section 734(b) adjustment on distributions, and the strategic decisions every partnership, LLC, fund, and family entity needs to think through.
Inside Basis vs. Outside Basis: Why the Mismatch Matters
To understand Section 754, you have to understand the two parallel basis tracks in every partnership.
Outside basis is what each partner has in their own partnership interest. It starts with what they paid (or contributed), goes up when they're allocated income or contribute capital, and goes down when they take distributions or get allocated losses. It lives on the partner's tax return.
Inside basis is the partnership's basis in the assets it owns — buildings, equipment, securities, intangibles. It lives on the partnership's books.
When a partnership is formed and everyone contributes cash, inside basis and outside basis line up perfectly. Partner A puts in $100,000 cash; the partnership has $100,000 of cash; A's outside basis is $100,000 and her share of the inside basis is $100,000.
The trouble starts later, when one of two things happens:
- A partner transfers an interest (by sale, exchange, gift, or death) at a price that doesn't match their share of inside basis.
- The partnership distributes property to a partner in a transaction that creates a gain, loss, or basis disparity.
In both situations, the new partner's outside basis no longer matches their share of the partnership's inside basis. Without a corrective mechanism, that mismatch gets paid for twice — once when the partner sells their interest or dies, and again when the partnership eventually sells the underlying asset.
Section 754 is the corrective mechanism. When in place, it triggers two operating provisions: Section 743(b) (for transfers of interests) and Section 734(b) (for distributions).
How Section 743(b) Works: Step-Up on a Partner Buy-In or Death
A Section 743(b) adjustment applies when a partnership interest is transferred by sale, exchange, or upon the death of a partner. The adjustment is only with respect to the transferee partner — the buyer or the heir. It does not affect the inside basis as seen by any continuing partner.
The formula is straightforward:
743(b) adjustment = Transferee's outside basis − Transferee's share of partnership's inside basis
If the result is positive, the partnership steps up its inside basis (with respect to that transferee) by that amount. If negative, it steps it down.
Worked Example: Death of a Partner
Back to the example from the introduction. Maria, Jack, and Lin formed an LLC years ago, each contributing $100,000. The LLC bought commercial real estate that has appreciated; the building is now worth $3,000,000 with an inside basis of $300,000 (each partner's share of inside basis = $100,000).
Maria dies. Her interest is worth $1,000,000 (one-third of $3,000,000). Under Section 1014, her son's outside basis is stepped up to $1,000,000.
Without a 754 election in place:
- Son's outside basis: $1,000,000
- Son's share of inside basis: $100,000
- When the LLC eventually sells the building for $3,000,000, son is allocated $900,000 of taxable gain on appreciation that occurred during Maria's lifetime — appreciation already taxed in her estate.
With a 754 election in place:
- 743(b) adjustment = $1,000,000 − $100,000 = $900,000 step-up
- This adjustment applies only to the son's share of partnership basis
- When the LLC sells the building, son recognizes $0 gain on the $900,000 of pre-death appreciation; only post-death appreciation flows through to him
The election doesn't change anyone else's tax. Jack and Lin are unaffected. The economic logic is clean: the son already paid (or his mother's estate paid) for the appreciation through the estate-tax step-up, so it shouldn't be re-taxed inside the partnership.
Worked Example: Sale of an Interest
The same mechanic works when an existing partner sells. Suppose a fund partnership has $500,000 of inside basis allocated to each of four equal partners. The assets are now worth $5,000,000 (so each partner's share of FMV is $1,250,000). Partner D sells her interest to E for $1,250,000 cash.
- E's outside basis: $1,250,000
- E's share of inside basis: $500,000
- 743(b) adjustment (if 754 is in place): $750,000 step-up
E now gets accelerated depreciation deductions on the share of inside basis allocable to depreciable property, plus a higher tax basis when those assets are eventually sold. D paid capital gains tax on her exit; E does not pay tax again on the same appreciation when the partnership disposes of the assets.
Without the 754 election, that $750,000 of "phantom appreciation" sits inside the partnership waiting to be taxed twice.
Section 755: Allocating the Adjustment Across Asset Classes
A 743(b) (or 734(b)) adjustment isn't just a number — it has to be allocated across the partnership's assets under Section 755. The allocation matters because it determines what type of income the adjustment offsets and how fast it gets recovered.
The mechanics:
- First, allocate between two classes: capital gain property (real estate, securities, capital assets) and ordinary income property (inventory, depreciation recapture, depreciable equipment).
- Within each class, allocate based on each asset's unrealized appreciation or depreciation as of the transfer date.
A step-up allocated to a 27.5-year residential building generates 27.5-year amortization for the transferee. A step-up allocated to 5-year equipment generates 5-year recovery. A step-up allocated to goodwill amortizes over 15 years under Section 197. A step-up allocated to land sits dormant until sale.
This is why a quality 754 election starts with a fair market value appraisal of every material asset at the time of transfer. Without it, you cannot correctly allocate the adjustment.
Section 734(b): Adjustments for Distributions
Section 734(b) is the parallel rule for distributions, not transfers of interests. It applies when:
- The partnership distributes property and the partner takes a basis in that property different from the partnership's basis in it (typically because the partner's outside basis is lower), or
- The partner recognizes gain on a distribution (a current cash distribution exceeding outside basis), or
- The partnership distributes property in liquidation of a partner's interest.
Unlike 743(b), a 734(b) adjustment affects the inside basis of partnership property for all remaining partners, not just one. It's a partnership-level adjustment, allocated under Section 755 across the remaining assets.
A negative 734(b) adjustment (basis decrease) only arises from a liquidating distribution where a partner takes property with a higher basis than the partnership's basis, or recognizes loss.
In practice, 734(b) shows up most often when a partner retires and the partnership pays them out. If the retiring partner recognizes gain on the cash payout (because the cash exceeds their outside basis), a 754 election allows the partnership to step up its remaining inside basis by that gain — meaning the remaining partners get the economic benefit of the basis the retiring partner "left behind."
Mandatory 743(b) Adjustments: The Substantial Built-In Loss Rule
Section 754 is generally elective. But Congress closed one loophole: if a partnership has a "substantial built-in loss" at the time an interest is transferred, the partnership must apply Section 743(b) — even without making a 754 election.
A substantial built-in loss exists if either:
- The partnership's adjusted basis in its property exceeds the fair market value of that property by more than $250,000, or
- The transferee partner would be allocated a loss of more than $250,000 if the partnership sold all its assets for FMV immediately after the transfer (this transferee-level test was added by the Tax Cuts and Jobs Act).
When this rule kicks in, the adjustment is a basis step-down — the transferee's share of inside basis is reduced to match their lower outside basis. The IRS doesn't want a new partner inheriting an inflated share of built-in loss they didn't actually pay for.
There is also a mandatory basis adjustment under Section 734(b) for distributions that produce a "substantial basis reduction" — a downward adjustment that would exceed $250,000. Again, the policy is symmetrical: large built-in losses can't move around through partnership mechanics without recognition.
If your partnership owns depreciated real estate, distressed assets, or impaired investments, these mandatory rules apply whether you want them or not. Plan for them at the time of every transfer.
How to Make the Election: Mechanics and Timing
The mechanics are deceptively simple — and easy to miss.
Step 1: File the election with the return. Attach a written statement to a timely-filed Form 1065 (including extensions) for the tax year in which the triggering event (transfer or distribution) occurs.
Step 2: Include the required content. The statement must contain (a) the name and address of the partnership and (b) an explicit declaration that the partnership elects under IRC Section 754 to apply the provisions of IRC Sections 734(b) and 743(b).
Step 3: Sign it. A partner with authority to sign the return must sign the statement.
Step 4: Make it once. The election applies to the year of the event and every subsequent year until revoked. You don't re-file it annually.
Step 5: Track and report. The partnership must report each 743(b) and 734(b) adjustment, by asset, on its tax returns going forward. Form 1065 and Schedules K-1 require disclosure of the adjustment amount and the assets it relates to. Each transferee partner with a 743(b) adjustment has their own basis layer that the partnership must track.
What Happens If You Miss the Deadline?
If a partnership wanted to make the election but missed the return deadline (including extensions), there are two paths forward:
- 9100 relief (Treas. Reg. § 301.9100): Request an automatic 12-month extension or, in cases of reasonable action and good faith, a discretionary extension. Discretionary 9100 relief requires a private letter ruling and a user fee — expensive but available if the missed election would cost the partnership significant tax savings.
- Wait for the next triggering event. If another transfer or distribution happens in a future year, the partnership can elect then. But the basis adjustment is only made for that future event, not retroactively.
Why You Might Not Want to Make the Election
A 754 election is sticky. Once made, it applies to every distribution and transfer in every future year. That has real costs.
Administrative Burden
Every transfer and every distribution becomes a basis-adjustment event. The partnership has to:
- Get FMV appraisals of all material assets at each transfer date.
- Allocate the adjustment across asset classes under Section 755.
- Track each transferee partner's basis layer separately.
- Compute and report the adjustment on Form 1065 and on each partner's Schedule K-1 (codes for 743(b) and 734(b) adjustments).
- Carry the adjustment forward through depreciation, amortization, and ultimate disposition.
For a partnership with frequent partner turnover (a private equity fund, a real estate syndicate, a family LLC with many heirs), this is a permanent line item on the CPA bill.
Forced Step-Downs
The 754 election cuts both ways. If FMV of partnership assets is less than inside basis at the time of a transfer, you get a mandatory step-down of the transferee's share of inside basis — reducing future depreciation deductions and increasing future gain. Once you've elected, you can't pick and choose which transfers to apply it to.
If your partnership owns assets that have declined in value (depressed real estate, troubled investments) and a partner sells out, the 754 election may hurt the buyer, not help them.
Hard to Revoke
A 754 election can only be revoked with permission of the Commissioner, by filing Form 15254, Request for Section 754 Revocation, no later than 30 days after the close of the partnership year for which the revocation is to take effect.
The IRS will not approve revocation if the primary purpose is to avoid stepping down basis on assets that have declined in value. Acceptable grounds for revocation typically involve administrative burden — for example, a significant change in the partnership's business, a substantial increase in assets, a change in the character of assets, or markedly increased partner turnover. Revocation is granted at the IRS's discretion, and you should expect to make a real factual showing.
When the Election Makes Sense
A 754 election is most beneficial when:
- Assets are appreciated (real estate, equity portfolios, operating businesses with goodwill).
- Partner turnover is expected (death, retirement, sale of interests, fund redemptions).
- The partnership has long-lived depreciable assets so a step-up generates years of accelerated depreciation.
- Estate planning matters — the election preserves the value of the estate-tax step-up under Section 1014 for partnership interests.
It is less compelling when:
- The partnership holds primarily cash or marketable securities (the inside/outside disparity is small and short-lived).
- The partnership's assets are depreciated below their basis.
- Turnover is rare and the administrative cost outweighs the benefit.
- The partnership is small, simple, and unlikely to see appreciation worth tracking.
Practical Strategies for Partnerships and Their Partners
Time the election to the right year. If you're forming a real estate LLC and know one partner is elderly or that the fund expects exits, evaluate making the election in the year of the first triggering event — not before.
Get appraisals contemporaneously. A 743(b) adjustment is only as good as the FMV documentation supporting it. Pay for a qualified appraisal at the transfer date; don't try to reconstruct values years later when the IRS asks.
Use buy-sell agreements that anticipate the election. Partnership and LLC operating agreements should specify whether the partnership will make a 754 election if requested by a transferee or estate, who bears the cost of appraisals, and how the adjustment will be allocated.
Coordinate with estate planning. For owners of closely-held partnerships and family LLCs, the 754 election is the bridge between the estate-tax step-up and the income-tax basis recovery. Without it, the step-up benefit dies at the LLC's tax door.
Plan for both directions. Remember that a 754 election forces step-downs as well as step-ups. If the partnership is heavily invested in depreciable assets that may decline in value, model the downside before electing.
Keep the basis schedules. A 754 election creates separate basis layers per transferee. Maintain those schedules carefully — they are essential for depreciation calculations, allocations on the K-1, and gain or loss on eventual disposition. Lost schedules become very expensive to reconstruct.
Reporting Requirements: What Goes on the Return
Once a 754 election is in place and triggered:
- Form 1065 — attach the election statement in the year of election; thereafter, report 743(b) and 734(b) adjustments on the appropriate schedules.
- Schedule K-1 — each transferee with a 743(b) adjustment receives disclosure of the adjustment amount (positive or negative) and the assets to which it relates.
- Depreciation schedules — the step-up to depreciable property is treated as a new asset with its own recovery period and convention. It is separately depreciated.
- Tracking spreadsheets — partnerships typically maintain a "754 ledger" tracking each transferee's basis layer by asset, with depreciation, dispositions, and remaining basis updated annually.
For the transferee partner, the 743(b) adjustment doesn't affect their outside basis (which was already set by their purchase price or fair market value at death). It changes their share of the partnership's inside basis — and therefore the gain, loss, depreciation, and amortization flowing through to them on the K-1 in future years.
Keep Your Partnership Books Clean from Day One
A Section 754 election creates basis layers that the partnership has to track for years — sometimes decades. Spreadsheets get lost, accountants change firms, and the IRS comes calling at the worst possible time. The partnerships that benefit most from this election are the ones that maintain disciplined, transparent records from the start.
