Opportunity Zone Funds After 2026: What Changed for Real Estate Investors

The Opportunity Zone program was written with a fixed end date. The 2025 tax law kept the old investments on their original clock and wrote new rules for money invested from 2027.

The Opportunity Zone program lets an investor defer tax on a capital gain by reinvesting it in a qualified opportunity fund (QOF), and — after a ten-year hold — exclude the fund investment's own appreciation from tax. Real estate is the most common use, because a fund that buys and substantially improves property in a designated census tract fits the rules naturally. Many QOFs are organized as partnerships and look, from the investor's side, very much like a syndication.

The program was written with fixed dates. Public Law 119-21, enacted on July 4, 2025, kept the original investments on their original clock and wrote a new set of rules for amounts invested after December 31, 2026. This page sets the two side by side. It is mechanics, not advice.

The original investments: the December 31, 2026 date¶

Under the original text of section 1400Z-2, deferred gain is included in income in the year of the earlier of a sale or exchange of the investment or December 31, 2026. The IRS FAQ says the same in plain terms: deferral ends on the earlier of an inclusion event or December 31, 2026.

The ten-year benefit is not lost. An investor who holds the QOF interest for at least ten years can still elect to step basis up to fair market value on a later sale, excluding the post-investment appreciation.

Money invested after December 31, 2026¶

For amounts invested after that date, the amended section 1400Z-2 replaces the fixed date with a rolling one.

Invested under the original rules

Invested after December 31, 2026

When deferred gain is taxed

Earlier of a sale or December 31, 2026

Earlier of a sale or 5 years after the investment

Basis increase

10% after 5 years, plus 5% after 7 years

10% after 5 years; 30% for a qualified rural opportunity fund

10-year election

Basis to fair market value on sale

Same, but fair market value is fixed at the 30-year anniversary for longer holds

New elections

No election for sales after December 31, 2026

The date bar is removed

Two details matter for real estate funds. First, a qualified rural opportunity fund earns a 30% basis increase instead of 10%; the law defines a "rural area" by excluding cities and towns over 50,000 inhabitants and the urbanized areas adjacent to them. Second, the amendment lowered the substantial improvement threshold for property in a zone made up entirely of rural area from 100% to 50% of basis — the IRS explains it in Notice 2025-50, which applies the change from July 4, 2025.

Hypothetical example

The deferral clock, original versus amended rules

An investor sells stock in 2026 with a $200,000 capital gain and invests it in a QOF.

Invested in November 2026 (original rules): the deferred $200,000 is included in income for 2026 — the same year as the sale. There is effectively no deferral; only the ten-year exclusion of the fund's own appreciation remains on offer.
Invested after December 31, 2026, within the 180-day window (amended rules): inclusion moves to the earlier of a sale or five years after the investment. If held five years, basis rises by 10% of the deferred gain, so $180,000 is included; in a qualified rural opportunity fund, 30%, so $140,000.

Whether a particular gain and investment date fall under the amended rules is a question for your tax adviser, not for this example.

How a gain reaches you through a partnership¶

Gains can reach you on a Schedule K-1 — for example, your share of gain when a syndication sells its property. The IRS FAQ says a partner can start the 180-day investment period on any of three dates: the last day of the partnership's tax year, the date the partnership's own 180-day period begins, or the unextended due date of the partnership's return. The date you receive the K-1 is not relevant.

Only capital gains and qualified section 1231 gains are eligible; ordinary gain, including the ordinary portion of depreciation recapture, is not. Each investment and each year's holding is reported on Form 8997, and the deferral election itself on Form 8949, per the IRS FAQ.

Opportunity Zone funds versus a 1031 exchange¶

Both defer tax on a gain from real estate, and they are often confused. A 1031 exchange defers gain on real property by exchanging it for like-kind real property, and a limited partner generally cannot exchange an LP interest on its own. A QOF investment defers capital gain from almost any source — stock, a business, a syndication's sale — but only the gain needs to be invested, and the fund must meet its own asset tests: the IRS FAQ describes the 90% standard for the fund and the "substantially all" thresholds for its property.

What to read in a QOF offering¶

New zone designations are part of the 2025 law too. Notice 2025-50 states that it does not cover the forthcoming round of nominations and designations, which Treasury and the IRS will address separately. Until that guidance is out, read any fund's description of where it may invest with that in mind.

Questions readers ask

When is gain deferred in an existing Opportunity Zone investment taxed?

For investments under the original rules, the IRS FAQ states that deferral ends on the earlier of an inclusion event or December 31, 2026. The deferred gain is therefore included in income for the 2026 tax year unless an inclusion event happened earlier.

What are the rules for money invested in a qualified opportunity fund after December 31, 2026?

As amended by Public Law 119-21, section 1400Z-2 includes deferred gain on the earlier of a sale of the investment or five years after it was made, increases basis by 10% of the deferred gain after five years (30% for a qualified rural opportunity fund), and keeps the 10-year election, with fair market value fixed at the 30-year anniversary for longer holds.

Is the 15% basis step-up for seven-year holds still available?

It applied under the original rules. The amended text for amounts invested after December 31, 2026 contains only the five-year increase of 10%, or 30% for a qualified rural opportunity fund.

How long do I have to invest a gain?

Generally 180 days from the sale. A partner whose gain is allocated through a partnership can, per the IRS FAQ, start the 180 days on the last day of the partnership's tax year, on the date the partnership's own period begins, or on the partnership return's unextended due date.
