How OZ 2.0 works
You sell an asset at a gain and, within 180 days, invest up to the amount of that gain in a qualified opportunity fund (QOF), a partnership or corporation that holds at least 90% of its assets in qualified property in a designated zone. On your return you elect to defer the gain. Under the rules for investments made after December 31, 2026:
- Rolling deferral. The deferred gain is included in the year that contains the earlier of the date you sell the QOF interest or five years after the investment. There is no longer a single national deadline.
- Basis step-up. If you hold five years, basis rises by 10% of the deferred gain, so 90% is taxed. For a qualified rural opportunity fund the step-up is 30%, so 70% is taxed.
- 10-year exclusion. If you hold at least 10 years and elect, basis in the QOF interest becomes fair market value when you sell, so the growth is excluded from federal income tax. For sales after year 30, basis is fixed at the value on the 30th anniversary.
Zones are redesignated every ten years; the first new map runs from January 1, 2027 through December 31, 2036 (IRC 1400Z-1, Rev. Proc. 2026-14).
The 2026 timing trap
Gain invested in a QOF during 2026 falls under the old rules, which force inclusion on December 31, 2026, so the deferral lasts only until your 2026 return. Notice 2026-40 confirms that gain realized on, before or after December 31, 2026 and invested on or after January 1, 2027 gets the new rules, as long as the investment is timely. A seller closing in late 2026 can often wait to invest until early 2027, inside the 180 days, rather than invest in 2026.
Installment sales and OZ 2.0
Installment payments are eligible gain. The regulations let each payment start its own 180-day window, or let you start the window on December 31 of the year the payments were received (Treas. Reg. 1.1400Z2(a)-1(b)(11)(viii)). That allows a ladder: each year's gain is invested as it arrives, each investment with its own five-year and ten-year clocks. Only the gain portion of each principal payment needs to be invested. Interest on the note and Section 1245 recapture are ordinary income and not eligible; recapture is also taxed in the year of sale under Section 453(i). Gain from a sale to a related party (more than 20% common ownership) is not eligible.
Who it fits, and who it does not
- Fits: sellers who would invest in real estate or operating businesses anyway and can hold for 10 years or more.
- Fits: sellers with cash outside the fund to pay the tax at year five, since the fund rarely distributes enough to cover it.
- Fits: sellers of land or rural property who can use a qualified rural fund and its 30% step-up.
- Does not fit: anyone who needs liquidity within 10 years.
- Does not fit: recapture-heavy or interest-heavy proceeds, which are not eligible.
- Does not fit: California residents counting on a state benefit; California does not conform to the deferral, the step-up or the exclusion.
Worked example
Assumptions (engine, 2026 federal rates used for every year as a simplification, married filing jointly, Texas, $150,000 of other income): a seller realizes $1,000,000 of long-term capital gain in early 2027 and invests that amount in a QOF within 180 days. The fund is held 10 years.
| Path | Gain taxed | When | Federal tax |
|---|---|---|---|
| No OZ: pay tax on the sale | $1,000,000 | Sale year | $216,113 |
| Standard QOF: 90% included at year five | $900,000 | Year five | $185,605 |
| Qualified rural QOF: 70% included at year five | $700,000 | Year five | $138,005 |
The step-up reduces the tax on the original gain by $30,508 (standard) or $78,108 (rural) and moves it five years out, but the full $1,000,000 is locked in the fund and the year-five tax must be paid from elsewhere. Any growth after 10 years is excluded from federal tax; a fund that loses value can wipe out the benefit. Numbers are illustrative engine output.
IRS stance and audit risk
Opportunity zones are a statutory incentive, not a listed transaction. Risks are compliance and investment risks: missing the 180-day window, a fund that fails the 90% asset test or the substantial improvement test, property in a zone that expired with the old map, or a disposition that triggers early inclusion. Investors file Form 8997 every year; OBBBA added new fund reporting with penalties under IRC 6726. The investor rules are still being written: Notice 2026-40 promised proposed regulations, and the existing regulation text still carries 2026 dates.
Costs and fees
- Fund fees: sponsor, management and acquisition fees, and selling commissions on brokered funds.
- Illiquidity: 10 years or more to reach the exclusion.
- The year-five tax with no matching distribution.
- Annual reporting and K-1 complexity; separate state tax treatment.
How it compares with a Section 453 installment sale
A plain installment sale spreads the gain over the note with no investment requirement: you choose the buyer, the rate and the security (down payment, first-position deed of trust or UCC lien, a personal guarantee from the buyer's owners, default and acceleration terms). OZ 2.0 defers for a fixed five years, trims the gain by 10% or 30%, and excludes growth, but only if you hand the gain to a fund for a decade.
Under OZ 2.0 they combine well: the note spreads the gain and each payment's gain portion can feed its own fund investment, which keeps each year's outside-cash need small. See opportunity zones for the original program and the opportunity zone vs 1031 comparison.
How Hans helps
The $5,000 Big Sale Tax Analysis models OZ 2.0 alone and laddered behind an installment sale, including the year-five tax and the fund return needed to beat paying tax and investing normally, side by side with the other paths. Hans does not select or sell funds. Start with the one-year vs spread estimate.
What to know
OZ 2.0 is a stronger and permanent program, but the tax break does not rescue a weak fund. The deferral is five years, the gain reduction is 10% (30% rural), the growth exclusion requires a 10-year hold, and the tax at year five comes due without a distribution. Interest, Section 1245 recapture and related-party gain are not eligible. Investments made in 2026 fall under the old rules, and California and some other states do not conform.
