Capital Gains Strategy, IRC §1400Z-2

Opportunity Zones

Qualified Opportunity Funds offer investors the ability to defer capital gains taxes and permanently exclude the appreciation on their OZ investment from federal income tax after a 10-year hold. With December 31, 2026 marking a critical recognition deadline, understanding the current landscape is essential for investors with unrealized or recently realized capital gains.

The Opportunity Zone Program: What Remains in 2025

The Opportunity Zone program was created by the Tax Cuts and Jobs Act of 2017 under IRC §§1400Z-1 and 1400Z-2. The program designated approximately 8,764 census tracts as Qualified Opportunity Zones (OZs) and incentivized investment in those areas by allowing investors to defer and partially reduce capital gains taxes, and permanently exclude gains from QOF investments held for 10+ years.

The program's benefit structure was tiered by investment holding period: invest in 2018, hold 5 years (to 2023), get a 10% basis step-up; hold 7 years (to 2025), get 15%. Those windows are closed. What remains, and it is genuinely powerful, is the 10-year exclusion provision under §1400Z-2(c).

For investors with significant capital gains in 2025 or early 2026, the program offers: (1) deferral of that gain until December 31, 2026, and (2) if the QOF interest is held for 10 years, permanent federal tax exclusion on all appreciation of the QOF investment. The tax on the original deferred gain is due in 2026 regardless, but the economics of 10 years of tax-free compounding on the invested capital can be highly compelling.

The OZ Benefit Structure: What Still Applies

BenefitStatus in 2025Notes
Deferral of original gainAvailable (expires Dec 31, 2026)Gain recognized on Dec 31, 2026 or earlier sale, no longer a multi-year deferral for most investors

15% basis step-up (7-year hold)ExpiredRequired investment by Dec 31, 2021
10-year exclusion of QOF appreciationFully AvailableThe most valuable benefit: all QOF investment gains excluded after 10-year hold
State tax exclusionVaries by stateMost states do not conform to OZ exclusion; California notably does not
The December 31, 2026 Recognition Deadline

All deferred OZ gains must be included in income no later than December 31, 2026. This is a statutory deadline that cannot be avoided regardless of whether the investor sells their QOF interest. Tax planning for this recognition event, including whether to recognize the gain in 2026 or earlier based on marginal rate expectations, is an active consideration for current OZ investors. Investors making new OZ investments in 2025 face approximately 1–2 years of deferral before the 2026 recognition deadline.

The 10-Year Exclusion: The Remaining Crown Jewel

Under §1400Z-2(c), a taxpayer who holds a QOF interest for at least 10 years and makes a timely election can treat the basis of that interest as equal to its fair market value at the time of disposition. In plain terms: all appreciation in the QOF investment over the 10-year period is permanently excluded from federal capital gains tax.

This exclusion applies to gains on the QOF investment itself, not the original deferred gain. If an investor rolls $1 million of capital gains into a QOF in 2025, that $1M was invested in a qualifying project, and the QOF interest is worth $4 million at the time of a 2035 sale, the $3 million of appreciation is entirely excluded from federal capital gains tax.

Illustrative: $1M OZ Investment, 10-Year Hold
Original capital gain invested in QOF (2025)$1,000,000
Deferred gain recognized (Dec 31, 2026), tax due~$238,000 (at 23.8%)
QOF value at 10-year sale (2035), assuming 8% annual growth~$2,159,000
Appreciation on QOF investment~$1,159,000
Federal capital gains tax on QOF appreciation$0 (permanently excluded)
Tax saved on QOF appreciation @ 23.8%~$275,842

What UHNW Investors Look For in a QOF

Asset Quality Over Tax Optimization

The 10-year exclusion is only valuable if the underlying QOF investment appreciates. A poorly underwritten real estate deal in a designated OZ that loses value produces no tax benefit, worse, you've deferred and then owed tax on a gain from a losing investment. Sophisticated OZ investors evaluate the underlying real estate or business fundamentals first, tax structure second.

Substantial Improvement Requirement

For real property in an OZ, the QOF must substantially improve the property, meaning additions to basis over a 30-month period must exceed the original basis of the building (not including land). This typically means significant construction or renovation, not a light rehab, and creates a natural quality floor on qualifying real estate projects.

Geographic and Sector Diversification

Institutional OZ funds allow investors to diversify across multiple zones, geographies, and property types within a single QOF structure, reducing concentration risk while preserving the tax benefit. Single-zone, single-asset funds carry higher risk and should be underwritten with particular care.

State Conformity Analysis

Several high-tax states, California, Massachusetts, New Jersey, and others, do not conform to the federal OZ exclusion. A California investor in the 37% federal bracket also faces 13.3% state capital gains tax that the OZ exclusion does not eliminate. Net-of-state-tax analysis is essential before committing to an OZ investment.

Is an Opportunity Zone Investment Right for You?

Investor with a significant short-term or long-term capital gain realized in 2025 or early 2026
Business owner who has sold or is considering selling a business generating a large capital gain
Real estate investor who has sold a property in a taxable transaction (not a 1031 exchange)
Long-term investor comfortable with a 10-year hold period in exchange for tax-free appreciation
Investor seeking exposure to real estate development projects with strong underlying fundamentals
Taxpayer in a high-federal-bracket state where the 23.8% federal exclusion alone justifies the strategy

Frequently Asked Questions

Is the Opportunity Zone program still worth pursuing in 2025 and 2026?
Yes, but the strategy looks different than it did in 2018. The 5-year and 7-year basis step-up benefits (10% and 15% reduction in original deferred gain) required investments made by 2019 and 2021 respectively, and are no longer available. The main benefit remaining is the 10-year exclusion: gains on the QOF investment itself are permanently excluded from tax if the investment is held for at least 10 years. For long-term investors deploying capital gains into high-quality QOF assets, the 10-year exclusion alone is an extremely powerful benefit.
When must the deferred original gain be recognized?
The deferred original gain must be included in income on the earlier of: (1) the date the QOF interest is sold or exchanged, or (2) December 31, 2026. This means virtually all OZ investors will face recognition of their deferred gain in the 2026 tax year regardless of whether they sell. This is not a reason to avoid the strategy, it simply means the deferral benefit is now 1–2 years (depending on when the investment was made), not indefinite. The long-term exclusion of QOF gains remains intact regardless.
What qualifies as a Qualified Opportunity Zone Business?
A QOZB must: (1) have at least 70% of its tangible business property in an OZ, (2) derive at least 50% of gross income from active conduct of business in the OZ, (3) have less than 5% of assets in 'sin business' categories (golf courses, country clubs, racetracks, liquor stores, etc.) and less than 5% in nonqualified financial property, and (4) use a substantial portion of intangible property in active conduct of business. Real estate development in OZs, where a substantial improvement doubles the building's value, is the most common qualifying structure.
Can I invest in an Opportunity Zone if I don't have a realized capital gain?
No. QOF investment eligibility requires a capital gain event, specifically, an 'eligible gain' from the sale or exchange of property to an unrelated party. Only that gain (not ordinary income, not previously recognized capital gains) can be rolled into a QOF within the 180-day window. W-2 income, ordinary business income, and other non-capital-gain sources do not qualify for the deferral, though such funds can still be invested alongside the gain investment in the QOF.
How does the 10-year exclusion actually work?
If a taxpayer holds their QOF interest for at least 10 years and makes a timely election under §1400Z-2(c), the basis of the QOF interest is stepped up to its fair market value at the time of sale. This means all appreciation in the QOF investment over the 10-year hold period is permanently excluded from federal capital gains tax. For example: $1M invested in a QOF that grows to $4M over 10 years = $3M of gain permanently excluded. At a 23.8% federal rate, that's $714,000 of tax eliminated entirely. State tax treatment varies.
