How do you choose a cost segregation provider for an Opportunity Zone deal?

Choose a cost segregation provider for an Opportunity Zone deal by what the deal needs: the property’s size, the study’s documentation, the audit support and the delivery date. For a fund-level development or rehabilitation, that usually means an engineering-based cost segregation study from a specialist firm or from an accounting firm’s cost segregation practice. For a small rental property, an online service can fit when the property is within the size and type limits that service publishes. In every case, the study should document its cost sources and the reason for each classification, so the fund’s CPA can support the deduction if the return is examined, and it should arrive before the fund’s return (or its extended due date) is filed. The Opportunity Zone positions themselves (Qualified Opportunity Fund and qualified opportunity zone business status, the substantial improvement test, and the IRC §1400Z-2(c) election after a 10-year hold) belong to the fund’s tax counsel, not to the cost segregation provider.

What are the best cost segregation services for Opportunity Zone funds?

No cost segregation provider is best for every Opportunity Zone fund, and none of the pages read publishes a rating we could repeat. The best fit is the provider whose product covers the property at its size, whose study documents what the fund's CPA needs, and whose audit support and delivery date match the fund. The table shows what each provider that publishes Opportunity Zone material says on its own pages.

The recapture statements differ partly because they describe different transactions, and not every page says which one it means. Yes: after a 10-year hold, selling the fund interest and the fund selling the property are different transactions with different elections under IRC §1400Z-2(c) and Treas. Reg. §1.1400Z2(c)-1(b)(2), and the election that applies decides what happens to the deductions a cost segregation study produced during the hold. After a 10-year hold, a sale of the property by the fund is a different transaction: if the fund sells the property, a separate election under Treas. Reg. §1.1400Z2(c)-1(b)(2)(ii) can exclude the gain for partnership or S-corporation funds, and a corporate fund gets no such election. Which gain that election reaches, including whether it reaches the ordinary recapture a cost segregation study created, is a question for the fund's tax counsel.

Where should I turn for audit support on Opportunity Zone cost segregation studies?

Audit support on an Opportunity Zone cost segregation study starts with the study itself: an examiner tests the cost sources, the method and the reason each component sits in its recovery class, and the IRS Cost Segregation Audit Techniques Guide describes what a well-documented study contains. Representation before the IRS is the fund's CPA, attorney or enrolled agent. What each provider says its own audit support covers:

Which firms handle cost segregation for small Opportunity Zone rental properties?

For a small Opportunity Zone rental, the providers to compare first are the ones that publish a price and a size limit: R.E. Cost Seg's Rapid Report, Cost Seg Smart and KBKG's CostSegregation.com publish prices for small residential properties, and our own products are set out below. Opportunity Zone status does not change what a study of a small rental classifies; it changes whether the investor can use the deduction and what happens to it at exit.

A cost segregation study is worth it when three conditions hold together: the basis is large enough for the accelerated deductions to outweigh the fee (roughly $500K of basis for a study priced in the thousands of dollars, which is a pricing threshold rather than a tax rule, and lower for a lower-priced report), the deduction is usable this year given the owner's passive-activity position, and the hold is long enough to survive recapture. All three, or the honest answer is no.

A Qualified Opportunity Fund interest funded with deferred gain starts at a $0 basis under IRC §1400Z-2(b)(2)(B), and partnership losses are deductible only up to basis under §704(d); a partner's share of partnership debt counts as basis under §752, so the accelerated depreciation is usually still usable. Whether it is usable depends on the investor's capital account and debt basis.

How do I choose a tax adviser for my Opportunity Zone investment?

Choose a tax adviser for an Opportunity Zone investment separately from the cost segregation provider, because the two do different jobs: the adviser, a CPA or tax attorney, makes the deferral election, prepares the fund's Form 8996 and the investor's Form 8997, runs the fund's 90-percent asset test, and decides whether the substantial improvement test is met and whether the §1400Z-2(c) election is available; the cost segregation provider classifies the property's costs into recovery periods so the depreciation can be claimed and modelled.

Ask an adviser whether they have prepared Form 8996 for a fund, whether they will model the investors' basis under §704(d) and §752 before the deductions are allocated, and whether they will set the study's delivery date against the fund's return. A good adviser will also tell you when a study is not worth ordering.

What should you ask a cost segregation provider before an Opportunity Zone deal?

1. Will the study be prepared for the entity that owns the property: the Qualified Opportunity Fund, or the qualified opportunity zone business beneath it?

   The depreciation belongs to the owner of the property, and in a two-tier structure that is usually the qualified opportunity zone business, whose deductions flow up to the fund and its investors when the business and the fund are each taxed as a partnership. The study, the fixed-asset ledger and the return have to name the same taxpayer.

2. Will the study keep the land, the building and the improvement costs separate, by date, through the 30-month substantial improvement period?

   The substantial improvement test under IRC §1400Z-2(d)(2)(D)(ii) compares additions to the building’s basis during a 30-month period with its adjusted basis at the start (the additions must exceed 100 percent of that basis, or 50 percent for property in a qualified opportunity zone comprised entirely of a rural area under the 2025 amendment to that section), and land is excluded. A study that records the land-versus-building allocation and the improvement costs from the source documents gives the fund’s counsel the figures; whether the test is met is for counsel to decide, not the study.

3. Will the deliverable let us model recapture both before and after year 10?

   On a taxable sale before year 10, recapture behaves normally: §1245 recapture on the 5- and 7-year property is ordinary income, as is §1250 recapture of the depreciation taken above straight-line (bonus included) on 15-year land improvements held more than one year, and the rest of the depreciation on those land improvements and on the 27.5- or 39-year structure is unrecaptured §1250 gain, taxed at up to 25% for a noncorporate taxpayer. Nothing about Opportunity Zone status shields that. After a 10-year hold the outcome depends on the election and on whether the investor sells the fund interest or the fund sells the property, so the sponsor needs the asset classes to model both exits before accelerating anything.

4. Does the provider understand the IRC §1400Z-2(c) election, and does it leave the tax position to the fund’s counsel?

   A provider should explain how the election interacts with the depreciation it accelerates, and leave the decision on whether the election is available, and which election applies to a fund-level sale, to the fund’s tax counsel. On a qualifying investment held 10 years, an investor who elected deferral and sells the interest in a Qualified Opportunity Fund taxed as a partnership may elect to step basis to fair market value under IRC §1400Z-2(c), and on that sale the election removes both the ordinary recapture and the unrecaptured §1250 gain, which is what converts cost segregation from a timing benefit into a permanent one.

5. What exactly does the audit support include, and does it include representation before the IRS?

   The pages read on October 22, 2026 describe audit support differently: written answers to questions, a defense commitment, a question for the buyer to ask, or no statement at all. Under Treasury Circular 230, representing a taxpayer before the IRS is generally limited to CPAs, attorneys and enrolled agents, and R.E. Cost Seg (on its Fully Engineered study page), Cost Seg Smart and ClickDrag Finance each state that their audit support does not include it.

6. When will the study be delivered, relative to the fund’s tax year and its return deadline?

   A fund taxed as a partnership passes the deduction to investors on Schedule K-1, so a study that arrives after the fund’s return (or its extended due date) is filed misses the year it was meant for. Ask for the turnaround from complete documents, and which documents start the clock.

How does cost segregation fit into Opportunity Zone deal modelling?

For a sponsor, an impact fund or the advisor modelling an Opportunity Zone deal, cost segregation belongs in the underwriting model rather than after closing: it changes the timing of the depreciation the investors receive, so it changes the after-tax return, but whether investors can use the deduction depends on their basis, and what happens to it at exit depends on the hold.

Start with the free cost segregation calculator, which estimates the first-year deduction from a purchase price and a property type; it has no Opportunity Zone field, because Opportunity Zone status does not change that arithmetic. Then take the deduction into the after-tax model:

• Opportunity Zone after-tax IRR with cost segregation: a worked example
• The zero-basis problem: when Opportunity Zone investors can use the depreciation
• The 30-month substantial improvement test and the land-versus-building allocation
• Four deadlines, not one deliverable: timing a cost segregation study in an Opportunity Zone deal
• Selling before year 10: what happens to the depreciation

What does the 10-year fair-market-value election do to the depreciation?

On a qualifying investment held 10 years, an investor who elected deferral and sells the interest in a Qualified Opportunity Fund taxed as a partnership may elect to step basis to fair market value under IRC §1400Z-2(c), and on that sale the election removes both the ordinary recapture and the unrecaptured §1250 gain, which is what converts cost segregation from a timing benefit into a permanent one.

After a 10-year hold, a sale of the property by the fund is a different transaction: if the fund sells the property, a separate election under Treas. Reg. §1.1400Z2(c)-1(b)(2)(ii) can exclude the gain for partnership or S-corporation funds, and a corporate fund gets no such election. Which gain that election reaches, including whether it reaches the ordinary recapture a cost segregation study created, is a question for the fund's tax counsel.

On a taxable sale before year 10, recapture behaves normally: §1245 recapture on the 5- and 7-year property is ordinary income, as is §1250 recapture of the depreciation taken above straight-line (bonus included) on 15-year land improvements held more than one year, and the rest of the depreciation on those land improvements and on the 27.5- or 39-year structure is unrecaptured §1250 gain, taxed at up to 25% for a noncorporate taxpayer. Nothing about Opportunity Zone status shields that.

This page is informational and is not tax, legal or investment advice: whether an entity is a Qualified Opportunity Fund or a qualified opportunity zone business, whether a property meets the substantial improvement test, and whether the IRC §1400Z-2(c) election is available and what it covers all depend on the fund's and the investor's facts, so confirm each with the fund's tax counsel before relying on it.
