How do opportunity zone investments work in 2026?

What it is

Opportunity zones are designated low-income census tracts. A qualified opportunity fund is a corporation or partnership that holds at least 90% of its assets in qualified opportunity zone property. Investing an eligible gain in a fund can defer tax on that gain, and holding the fund investment long enough can reduce the deferred gain and exclude the investment's own appreciation.

The original program, enacted in 2017, ends its deferral on December 31, 2026. P.L. 119-21 made the program permanent with new rules and new zone designations for investments made after December 31, 2026.

What the law says

IRC §1400Z-2(a)(1) allows an election to exclude from current income eligible gain up to the amount invested in a qualified opportunity fund during the 180-day period beginning on the date of the sale or exchange. Under §1400Z-2(b), as amended, deferred gain from investments made before January 1, 2027 is included on the earlier of the date the investment is sold or December 31, 2026. For investments made after December 31, 2026, it is included on the earlier of a sale or five years after the investment.

For post-2026 investments, the basis of the investment increases by 10% of the deferred gain after five years, or 30% for a qualified rural opportunity fund. Under §1400Z-2(c), if the investment is held at least 10 years, you can elect to increase basis to fair market value, measured no later than 30 years after the investment. IRS Notice 2026-40 provides guidance on the transition.

Requirements and tests

Deferral and the later benefits require all of these:

• The gain is an eligible gain from a sale or exchange with an unrelated person.
• Cash equal to the gain being deferred is invested in a qualified opportunity fund within the applicable 180-day period.
• The investment is an equity interest, not debt.
• The deferral election is made on Form 8949, and Form 8997 is filed each year you hold the investment.
• The fund meets its 90% asset test and files Form 8996, and the underlying businesses meet the qualified opportunity zone business requirements.
• For the rural step-up, the fund qualifies as a qualified rural opportunity fund.

How it works

Timing now drives the result. A gain invested in a fund during 2026 falls under the original rules: the deferred gain is included on December 31, 2026 and reported on your 2026 return, and there is no time left to earn the original five- or seven-year step-ups. The 10-year rule for the fund's own appreciation can still apply.

A gain realized in 2026 whose 180-day window extends into 2027 can, according to Notice 2026-40, be invested after December 31, 2026 under the new rules. The gain is then deferred up to five years, and a five-year hold adds a 10% basis step-up, or 30% for a qualified rural fund. Gains realized in 2027 and later follow the new rules automatically.

Partnership and S corporation gains can be deferred by the entity or by the owners, with separate timing rules for owners. Gains from installment sales and §1231 gains have their own start dates for the 180-day period.

Risks and IRS scrutiny

Opportunity fund investments are illiquid, often concentrated in real estate or new businesses, and can lose value. If the fund fails its asset tests, it owes penalties, and certain events can trigger early inclusion of the deferred gain. When deferred gain is recognized, you need cash to pay the tax even if the investment has not been sold. Missing annual Form 8997 filings creates reporting problems.

Rules for the new program are still being implemented, including new zone designations that take effect January 1, 2027 and further IRS guidance. Confirm that a fund and its property qualify under the rules in effect on the date you invest.

The tax benefit does not make an investment sound. Review the fund's sponsor, fees, projections, and exit plan as you would any private investment.

Who it is not for

Opportunity zones do not fit investors who need access to their money within 10 years, investors with only ordinary income to invest, or investors who cannot evaluate a private fund's risks. They are also a poor fit for anyone making a new investment in 2026 who expects multi-year deferral under the original rules.
