For an appraiser valuing an Opportunity Zone property, cost segregation is not just a tax footnote; it can affect the cash-flow model that a QOF investor uses to bid, hold, refinance, or sell. A cost segregation study can move portions of a building from long-life real property into shorter-life property under IRC §168, and that timing difference can matter when the buyer is underwriting an after-tax return inside IRC §1400Z-2.
The appraiser’s niche question is narrow: when a QOF investor expects to make the IRC §1400Z-2(c) fair-market-value step-up election after a 10-year hold, does cost segregation create depreciation recapture that still reduces exit proceeds, or does the OZ exclusion change the result? That question belongs in the valuation file because cost segregation can increase early deductions, but the appraiser must decide whether those deductions are a market participant benefit, an owner-specific benefit, or an adjustment that belongs only in an investment-value scenario.
In an OZ assignment, the tax value of accelerated depreciation can be visible in the bids even when the bricks, leases, and location have not changed.

Why does an appraiser care about OZ depreciation instead of only rent and cap rate?
An appraiser cares about OZ depreciation when market participants are QOF investors that price assets using after-tax cash flow under IRC §1400Z-2. In that setting, the same net operating income can support a different bid if a buyer expects accelerated deductions from cost segregation during the hold and a tax-favored exit after the IRC §1400Z-2(c) 10-year holding period.
That does not mean the appraiser should automatically increase market value by the tax savings. It means the appraiser should identify whether the likely buyer pool includes QOFs, whether the property is qualified opportunity zone business property, and whether the buyers commonly commission cost segregation studies as part of acquisition or placed-in-service planning. A stabilized multifamily asset in an active OZ submarket may attract tax-motivated capital differently than a conventional buyer pool.
For a market-value assignment, the appraiser typically separates real estate fundamentals from investor-specific tax attributes. For an investment-value assignment, the appraiser may model the QOF’s after-tax economics directly, including depreciation timing under IRC §168 and the potential exclusion of eligible gain after a 10-year hold with the election under IRC §1400Z-2(c). The report language should make that distinction clear because a tax benefit available to one buyer may not be available to all buyers.
If you are reviewing whether the property is a candidate for a cost segregation study, our Opportunity Zone cost segregation resource explains how the study fits inside OZ compliance and depreciation planning.
How should an appraiser model depreciation recapture in an OZ exit after year 10?
An appraiser should model depreciation recapture as eliminated for an investor who sells a qualifying QOF interest after holding it 10 years and who makes the IRC §1400Z-2(c) election, because the election steps the basis of the interest up to fair market value and recapture is capped at gain; before year 10, or without the election, recapture applies normally. Where the QOF instead sells its own assets, whether the investor can exclude the passed-through gain, including recapture items, depends on that investor’s own 10-year holding period and election under Treas. Reg. §1.1400Z2(c)-1, so the valuation file should say which exit it assumes. The full mechanics for investors are in the 10-year exclusion and recapture, for LPs, and the mirror case is recapture on an early OZ exit.
Depreciation recapture is normally a tax cost on a taxable sale because IRC §1245 recaptures prior depreciation on tangible personal property as ordinary income, and gain on depreciable real property is subject to IRC §1250, under which depreciation that is not recaptured as ordinary income is generally taxed as unrecaptured §1250 gain at up to 25% under IRC §1(h). Cost segregation increases the amount of property that may be classified as IRC §1245 property, such as certain electrical, plumbing, specialty, or equipment-related components, depending on the facts documented in the study; 15-year land improvements such as paving and site utilities are generally §1250 property, not §1245 property.
Inside a qualifying OZ exit after the 10-year holding period and with the IRC §1400Z-2(c) fair-market-value basis election, the investor’s underwriting can treat the depreciation recapture on a sale of the QOF interest as eliminated, because the step-up leaves no gain for it to attach to. In a nonqualifying exit before that IRC §1400Z-2(c) holding period is met, the same accelerated deductions may create ordinary-income recapture exposure under IRC §1245 and additional real-property recapture analysis under IRC §1250.
This is why cost segregation can be especially valuable in an OZ valuation model. The deductions may arrive early under IRC §168, while the exit tax may be reduced after a 10-year hold if the investor satisfies the OZ rules and makes the IRC §1400Z-2(c) election. An appraiser should not decide the tax result, but the appraiser should ask whether the client’s scenario assumes a qualifying step-up, an early sale, or a mixed asset-sale structure.
How should an appraiser treat 5-, 7-, and 15-year property in an OZ valuation?
An appraiser should treat 5-, 7-, and 15-year property as timing-sensitive depreciation categories under IRC §168 when a cost segregation study reclassifies eligible building components. These categories can create faster deductions than real property lives, and the value impact depends on the buyer’s tax capacity, passive-loss position, debt allocations, and ability to use deductions.
Under IRC §168(k) as amended by OBBBA 2025, 100% bonus depreciation applies to qualified property acquired after January 19, 2025, when the property otherwise satisfies the statutory requirements. For written binding contracts, IRS Notice 2026-11 ties the acquired date to the latest of the date the contract was signed, the date it became enforceable under state law, the end of any cancellation period, and the date any contingency was satisfied under Treas. Reg. §1.168(k)-2(b)(5)(ii)(B).
If the agreement is not a written binding contract because it is not enforceable under state law or limits damages to a specified amount such as through a liquidated damages clause, the acquired date is generally when the taxpayer has paid or incurred more than 10 percent of the total cost excluding land and preliminary activities under Treas. Reg. §1.168(k)-2(b)(5)(iii) and Treas. Reg. §1.168(k)-2(b)(5)(v). For self-constructed property, including property built for the taxpayer under a written binding contract entered into before construction began, the property is acquired when physical work of a significant nature begins, and paying or incurring more than 10 percent of the total cost excluding land and preliminary activities is a safe harbor under Treas. Reg. §1.168(k)-2(b)(5)(iv).
Those acquisition-date rules matter to the appraiser because an OZ buyer’s bid may assume immediate bonus depreciation, while another buyer may assume a slower schedule. The appraiser can model the effect as a sensitivity rather than embedding it in the base real estate value, unless market evidence shows that QOF buyers are consistently pricing the tax benefit into transactions.
What acquisition date assumptions matter for bonus depreciation in an OZ appraisal?
The most important acquisition-date assumption is whether the tax model uses the acquired date required by IRC §168(k) as interpreted by IRS Notice 2026-11, rather than a shorthand closing-date assumption. An appraiser reviewing a QOF acquisition model should ask the sponsor whether the bonus depreciation assumption follows the written binding contract rule, the nonbinding-contract payment threshold rule, or the self-constructed property rule.
That question becomes more important in OZ projects with phased construction. A hotel, mixed-use building, or industrial conversion may include property placed in service at different times, and each placed-in-service component may have a different depreciation start date under IRC §168. A cost segregation study can help identify which assets were placed in service and which assets remain in construction, but the appraiser should not treat the entire project as one depreciation block unless the tax advisor has reviewed that approach.
For appraisers, the practical takeaway is documentation. If the sponsor’s valuation package assumes 100% bonus depreciation under IRC §168(k) as amended by OBBBA 2025 for qualified property acquired after January 19, 2025, the appraiser should request the contract timeline, contingency timeline, construction timeline, and placed-in-service support. Those documents help determine whether the tax benefit is a current cash-flow item or a future sensitivity.
How can a cost segregation study change the value narrative without changing market value?
A cost segregation study can change the value narrative by explaining why a QOF buyer may pay more, accept a lower pre-tax yield, or prefer a property with more reclassifiable components under IRC §168. The study does not itself create rent, occupancy, or physical utility, but it can affect after-tax yield when the buyer can use the deductions.
For market value, the appraiser should ask whether the tax benefit is typical for the likely buyer pool. If most likely buyers are conventional real estate investors that do not invest through QOFs, the tax benefit may be owner-specific. If the likely buyers are QOFs competing for assets in designated OZ tracts, the benefit may influence transaction behavior.
For investment value, the appraiser can model cost segregation directly. The model may show faster deductions from 5-, 7-, and 15-year property under IRC §168, possible 100% bonus depreciation under IRC §168(k) as amended by OBBBA 2025 for qualified property acquired after January 19, 2025, and reduced exit tax assumptions after a 10-year hold with the IRC §1400Z-2(c) election. That model should also show the alternative result if the investor sells before the qualifying holding period and faces recapture under IRC §1245 or IRC §1250.
Partnership economics can also affect the value of deductions. If the QOF or QOZB is taxed as a partnership, IRC §704(d) can limit a partner’s ability to use losses to the partner’s basis, and IRC §752 can increase or decrease basis through the partner’s share of liabilities. An appraiser does not compute partner-level tax, but the appraiser should know that depreciation value may vary by investor even when the property-level study is the same.
What valuation workpapers should ask for from the sponsor or QOF?
An appraiser valuing an OZ property with a cost segregation angle should request the acquisition documents, construction documents, placed-in-service schedule, depreciation schedules, and any engineering-based cost segregation report built on the methodology in the IRS Cost Segregation Audit Techniques Guide. The request should also ask whether the valuation is for market value, investment value, financing, financial reporting, or transaction support.
The workpapers should identify the assumed OZ path. If the model assumes a qualifying exit after the 10-year holding period with the IRC §1400Z-2(c) election, the file should say so in the same place where it describes the exit tax assumption. If the model assumes an early sale, the file should note that depreciation recapture under IRC §1245 and IRC §1250 may affect after-tax proceeds.
When the current owner or QOF placed a property it still owns in service in an earlier tax year and missed depreciation on it, a look-back cost segregation study may be relevant to the current valuation package; Form 3115 is filed by the taxpayer that owns the property, and a buyer that takes a cost basis starts its own depreciation from the purchase. Under the automatic change procedures of Rev. Proc. 2015-13 and section 6.01 of Rev. Proc. 2025-23, the missed depreciation is claimed on Form 3115 with no amended returns when the property has been depreciated on two or more filed returns, or on one filed return if the taxpayer placed it in service in the tax year immediately before the year of change (the year of the return the Form 3115 is filed with), and the taxpayer still owned the property at the start of the year of change and meets the other eligibility rules.

Frequently Asked Questions
Does cost segregation increase the appraised value of an OZ property?
Cost segregation does not automatically increase the appraised value of an OZ property. It can affect a QOF investor’s after-tax investment value when the buyer can use accelerated depreciation under IRC §168 and expects a qualifying exit after the 10-year holding period with the IRC §1400Z-2(c) election.
Does OZ depreciation recapture disappear after the 10-year hold?
For an investor who sells a qualifying QOF interest after a 10-year hold and makes the IRC §1400Z-2(c) fair-market-value basis election, the depreciation recapture is eliminated, because the basis step-up leaves no gain for it to attach to. If the investor sells before year 10 or without the election, recapture under IRC §1245 and unrecaptured §1250 gain apply normally.
Should an appraiser rely on a cost segregation study in the valuation file?
An appraiser can use a cost segregation study as tax-depreciation support when the assignment includes after-tax modeling. The appraiser should still separate property-level value evidence from investor-specific tax assumptions and should confirm tax treatment with the client’s tax advisor.
Why do 5-, 7-, and 15-year depreciation categories matter in an OZ appraisal?
The 5-, 7-, and 15-year categories matter because IRC §168 can accelerate deductions when a cost segregation study identifies qualifying assets. Faster deductions can improve early-year after-tax cash flow for a QOF investor that has basis and tax capacity to use them.
What bonus depreciation assumption should an OZ appraiser check first?
The appraiser should first check whether the model applies IRC §168(k) as amended by OBBBA 2025 to qualified property acquired after January 19, 2025. For property bought under a written binding contract, IRS Notice 2026-11 uses the latest of the date the contract was signed, became enforceable, cleared any cancellation period and had its contingencies satisfied under Treas. Reg. §1.168(k)-2(b)(5)(ii)(B), not the closing date.
