What is the 10-year rule for Opportunity Zones?

The 10-year rule is the most significant tax benefit available under the Opportunity Zone program. It allows appreciation generated inside a Qualified Opportunity Fund (QOF) to be excluded from federal capital gains tax, provided the investment is held for at least 10 years.

This rule applies under both the original OZ framework and the permanent Opportunity Zones 2.0 regime established by the One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025.

How the 10-Year Rule Works

If a QOF investment is held for at least 10 years, the taxpayer may elect to step up the basis of the QOF interest to its fair market value upon sale or exchange. Because the basis is stepped up to fair market value at disposition, the gain generated during the holding period is excluded from federal capital gains tax.

Important: This exclusion applies only to appreciation on the QOF investment itself. It does not eliminate the original deferred gain that was rolled into the QOF; that gain is recognized separately under the applicable deferral rules (see below).

What Gains Are Excluded?

The 10-year rule excludes federal capital gains tax on the increase in value of the QOF investment after it was acquired.

For example: if $1 million of capital gains is reinvested into a QOF and the investment grows to $3 million after more than 10 years, the $2 million of appreciation may be excluded from federal capital gains tax — provided the basis step-up election is properly made.

The original $1 million deferred gain is taxed separately according to the applicable OZ 1.0 or OZ 2.0 deferral timing rules.

The Two Eras: OZ 1.0 vs. OZ 2.0

Because the OBBBA created a new framework for investments made after December 31, 2026, the rules that apply to your investment depend on when it was made.

OZ 1.0: Investments Made Before January 1, 2027

• Deferral: The invested gain must be recognized no later than December 31, 2026 (or upon earlier exit from the fund).
• Basis step-up: Investors who held for at least 5 years before December 31, 2026 received a 10% step-up on the deferred gain; a 7-year hold qualified for an additional 5% (15% total). These windows have now largely passed.
• 10-year exclusion: Fully available. Investors holding their QOF interest for at least 10 years may exclude all post-acquisition appreciation from federal capital gains tax. Under the OZ 1.0 regime, tax-free growth is permitted only through December 31, 2047, at which point the QOF interest’s basis must be stepped up to fair market value.

OZ 2.0: Investments Made On or After January 1, 2027

• Rolling deferral: Capital gains are deferred for 5 years from the date of investment — no fixed calendar sunset.
• 10% basis step-up at 5 years: A single 10% step-up on the deferred gain after a 5-year hold. The 7-year 15% step-up from OZ 1.0 has been eliminated. Note: the basis step-up at the 5-year mark is 30% for investments in Qualified Rural Opportunity Funds (QROFs).
• 10-year exclusion: All post-acquisition appreciation is excluded from federal capital gains tax after a 10-year hold. Under the OZ 2.0 regime, tax-free growth is permitted for a period of 30 years, at which point the QOF interest’s basis must be stepped up to fair market value.

Does the 10-Year Rule Eliminate Depreciation Recapture?

When structured properly, the 10-year basis step-up election may also eliminate federal depreciation recapture upon sale of the QOF interest. This applies in both the OZ 1.0 and OZ 2.0 regimes.

In a traditional real estate transaction, depreciation taken during the holding period is typically recaptured and taxed upon sale. Under the OZ structure, if the QOF investment is held for at least 10 years and the basis is stepped up to fair market value at disposition, both appreciation and depreciation recapture may be excluded from federal taxation.

Is the 10-Year Exclusion Automatic?

No. The basis step-up to fair market value requires an affirmative election on the taxpayer’s federal income tax return for the year of sale. Proper compliance, structuring, and documentation are essential to ensure the exclusion applies as intended.

Timing Considerations for 2026–2027

Investors should pay close attention to the transition period. Capital gains invested before December 31, 2026 remain subject to OZ 1.0 rules, including the 2026 recognition date for deferred gains. Gains realized in the second half of 2026 may fall within a 180-day investment window that extends into 2027, potentially qualifying for the more favorable OZ 2.0 rules under the OBBBA. A qualified tax advisor can help determine which framework applies to your situation.

Key Considerations Before Investing

• Liquidity: A 10-year hold is a meaningful commitment. Exiting early forfeits the appreciation exclusion. Assess your liquidity needs carefully before investing.
• Zone eligibility: Current 2018 OZ designations expire at the end of 2026. New designations under the OBBBA take effect January 1, 2027. The new zones will carry the full OZ 2.0 benefit structure.
• Due diligence: The tax benefit is only as valuable as the underlying investment. Evaluate the fund manager’s track record, project feasibility, and QOF compliance before committing capital.
• Reporting requirements: The OBBBA introduced enhanced reporting obligations for QOFs and QOZBs, with significant penalties for non-compliance. Confirm your fund is meeting its new reporting duties.

Bottom line: The 10-year rule remains the most powerful reason to invest in Opportunity Zones. Whether investing under OZ 1.0 or the new permanent OZ 2.0 framework, holding a QOF investment for at least a decade unlocks complete exclusion of post-acquisition appreciation from federal capital gains tax. With the program now permanent, the 10-year rule is a durable and increasingly compelling wealth-building tool.
