Why This Mechanic Matters More Inside an Opportunity Zone Fund
A Qualified Opportunity Fund is, in most structures, a partnership for tax purposes. That means every rule that governs partnership-interest transfers governs QOF LP transfers too — including §754 and the §743(b) basis adjustment that fires when a partnership makes the election and a partner is bought out, inherited from, or otherwise steps out. Layer a cost segregation study on top and the transferee's new depreciable basis rides the 5-, 7-, and 15-year buckets exactly the way it does in a non-OZ partnership. What is different is the ten-year exit: for a transferee who reaches the §1400Z-2(c) FMV election on their QOF interest, the depreciation recapture that normally comes home at sale is excluded — which turns the accelerated cost segregation deductions from a timing benefit into a permanent one.
We covered the general §754 / §743(b) partner-basis cost segregation mechanic in Section 754 and Cost Segregation: How a Partnership Buy-Out Creates New Depreciable Basis. This post is the QOF-specific companion: the mechanic is the same, the inputs are the same, but the exit math changes the answer to "was cost seg worth it?" in a way that non-OZ partnerships never see.
The §754 Election Applies to QOFs the Same Way It Applies to Any Partnership
Under IRC §754, a partnership may elect to adjust the inside basis of its assets when a partnership interest is transferred (§743(b)) or when a distribution is made (§734(b)). The election is generally irrevocable and, once made, applies to every subsequent transfer. Because a QOF is a partnership, the QOF's operating agreement and its Form 1065 are where the §754 election lives — not the underlying qualified opportunity zone business (QOZB) or the real property it holds. Sponsors who intend to accommodate secondary transfers of LP interests should get the §754 election on the fund's return early; the sponsor is the one filing.
Under §743(b), if an election under §754 is in effect, the transferee partner takes an adjustment to the basis of partnership property equal to the excess of the transferee's outside basis over the transferee's share of the adjusted basis of partnership property. — Framework of IRC §743(b) and §754
What Triggers a §743(b) Adjustment Inside a QOF
The trigger events are the same as in any partnership — a purchase of one LP's interest by another party, a §1014 inheritance after an LP's death, and certain other transfers. Note that on the seller's side, a pre-ten-year sale of a QOF interest is itself an inclusion event under §1400Z-2(b): the seller recognises their original deferred gain in that year. On the buyer's side, they acquire a new QOF interest at the purchase price, start their own fresh ten-year clock, and — with a §754 election in place — get a §743(b) adjustment on their share of the fund's inside basis.
The §743(b) adjustment is allocated under §755 across the fund's assets. Land takes its share and does nothing depreciable with it; depreciable improvements take theirs, and the cost segregation study of the underlying real estate decides how much of that lands in the 5-, 7-, 15-, 27.5-, or 39-year buckets. The output is a §743(b) supplement to the study that the CPA drops into the K-1 attachment under §754.
How Cost Segregation on a §743(b) Step-Up Interacts With the Ten-Year Exit
Inside an OZ fund, the ten-year hold lets the LP elect under §1400Z-2(c) to treat the basis of their QOF interest as its fair market value on the date of sale. The election excludes appreciation and — critically for anyone who took accelerated cost segregation deductions — depreciation recapture on the gain attributable to those deductions. Both layers of gain that normally arrive at exit are excluded to the extent the election applies.
For a transferee who bought a QOF interest, got a §743(b) step-up, and used a cost segregation study to accelerate depreciation on the stepped-up basis, this changes the exit math. Outside a QOF, the accelerated deductions come back as §1245 ordinary recapture on the short-life components and unrecaptured §1250 gain on the shell. Inside a QOF held ten years, both are excluded. The accelerated depreciation the transferee claimed is permanent, not deferred. That is why the §754 / §743(b) mechanic is worth more per dollar inside an OZ fund than it is anywhere else — the same cost seg study, applied to the same §743(b) adjustment, produces a bigger after-tax result because recapture never arrives.

Purchase vs Inheritance: The Bonus Depreciation Split, QOF Edition
The general purchase-vs-inheritance split for bonus depreciation applies inside a QOF exactly as it does outside. For a purchase-triggered §743(b) adjustment (one LP buys another out), the step-up is treated as a separately-depreciable acquisition per Treas. Reg. §1.168(k)-2(b)(3)(iv)(D). Under OBBBA, bonus is 100% for property with a written binding contract date after January 19, 2025 (IRS Notice 2026-11 confirmed the acquired-date test turns on the contract date, not the closing date). Contract dates before that fall onto the TCJA phase-down.
For an inheritance-triggered adjustment (§1014 step-up flowing through §743(b) after an LP's death), the transferee's slice is "used property acquired from a related person" under Treas. Reg. §1.168(k)-2(b)(3)(iv)(C) and does not qualify for bonus depreciation. Note also that under §1400Z-2(b)(2)(B)(iv) and the related regulations, transfer of a QOF interest at death is generally not an inclusion event — the heir tacks the decedent's holding period. So an inherited QOF interest often reaches the ten-year mark faster than a purchased one, meaning the exclusion-of-recapture benefit arrives sooner, but the transferee's own accelerated depreciation on any §743(b) step-up during the hold is not bonus-accelerated.
When Does the §754 Election Actually Matter for a QOF Sponsor?
Sponsors sometimes assume that because early LP transfers are rare — and the ten-year hold discourages them — the §754 election is not worth the operational overhead. Two situations flip that:
- Secondary-market LP transfers. Some QOFs run explicit secondary-market activity (family-office-to-family-office resales, GP-led continuation vehicles). Every purchase-triggered transfer with §754 in place produces a §743(b) step-up for the buyer, and a cost segregation study on the underlying property makes that step-up productive. Without the election, the buyer sees an outside-basis step-up that does nothing until they exit.
- Estate transfers of LP interests. Even without a secondary market, LPs die during a ten-year hold. Heirs get §1014 step-up on the outside basis; with §754 in place, they get a §743(b) adjustment on the inside basis too. That adjustment can be cost-segregated (though the bonus-depreciation portion is excluded per the used-property rule above), and the accelerated depreciation runs during the remainder of the hold.
Both are situations the operating agreement can silently address by adopting the §754 election on the fund's initial 1065. Adding it later is possible via late-consent procedures (Rev. Proc. 2020-23 and successors), but the sponsor's CPA has to actively file it.
Frequently Asked Questions
Does a QOF need a §754 election to get the cost segregation benefit on its underlying property?
No — the fund's own property-level cost segregation study runs regardless of whether §754 is elected. The §754 election matters specifically for LP-interest transfers: without it, a transferee's outside-basis step-up does not create new depreciable basis, and there is nothing extra for the cost segregation study to allocate on the transferee's side. The QOF's ordinary annual depreciation on the underlying property continues either way.
What happens to the accelerated depreciation from a §743(b) cost segregation study when the transferee sells their QOF interest after ten years?
The §1400Z-2(c) FMV basis election at the ten-year mark excludes gain on the QOF interest — including the portion attributable to accelerated depreciation. Both §1245 ordinary recapture on the short-life 5-, 7-, and 15-year property and unrecaptured §1250 gain on the shell are excluded to the extent the election applies. The accelerated cost segregation deductions the transferee claimed during the hold become permanent tax benefits, not deferred ones.
Can bonus depreciation apply to a §743(b) adjustment inside a QOF?
Yes for purchase-triggered adjustments with a contract date after January 19, 2025 (100% bonus under OBBBA per IRS Notice 2026-11); no for inheritance-triggered adjustments (excluded from bonus as used property acquired from a related person per Treas. Reg. §1.168(k)-2(b)(3)(iv)(C)). The QOF setting does not change the bonus depreciation rules — it changes what happens to the recapture at exit.
If the QOF's underlying property has already been cost-segregated at the fund level, do we run a fresh study for the §743(b) supplement?
No. The recovery-period percentages are properties of the real estate and do not change because an LP interest changed hands. The §743(b) supplement applies the existing cost segregation study's per-bucket percentages to the transferee's new basis adjustment. The engagement is materially shorter than a from-scratch study, because the underlying engineering work is already done.
How does the ten-year clock work for the transferee?
A purchaser of a QOF interest starts a fresh ten-year clock on the date of purchase — their §1400Z-2(c) FMV election becomes available ten years from that date, not from the fund's original placed-in-service date. An heir under §1014 tacks the decedent's holding period under §1400Z-2(b)(2)(B)(iv), so the ten-year mark can arrive sooner. This matters for the cost segregation study's economics: the accelerated deductions are worth more if the transferee can reach the FMV election within their hold, because that is what makes the depreciation permanent rather than deferred.
What if the sponsor never made the §754 election and now wants to accommodate a secondary transfer?
A late §754 election is possible via automatic-consent revenue procedures (Rev. Proc. 2020-23 and successors), and the sponsor's CPA files it. Until the election lands the transferee's outside-basis step-up does nothing for depreciation. Sponsors who anticipate any secondary activity — including estate transfers — should make the election early rather than scrambling for a late one.
Getting Started
If you're a QOF sponsor considering (or accepting) an LP transfer, or an LP contemplating buying into an existing fund's secondary market, the §754 / §743(b) cost segregation engagement typically runs 3–4 weeks when the fund's underlying property has already been cost-segregated (we apply the existing percentages to your new §743(b) adjustment), 5–7 weeks when it has not (fresh property-level study plus the §743(b) supplement).
