Opportunity Zones for CPAs and financial advisers

Start with character and timing: the gain must be capital gain (or gross §1231 gain) that is recognized for federal income tax, from a sale to an unrelated person, and the 180-day window begins when the gain would be recognized. The statute sets the 180-day rule in §1400Z-2(a)¹, and the final regulations fill in start dates and character rules^2,3.

Depreciation recapture taxed as ordinary income under §1245 or §1250 is not eligible⁴. Installment method reporting follows the general rules; recapture is reported in the year of sale even on an installment sale¹⁵. See which gains qualify and section 1231 gains.

The client invests cash for QOF equity within 180 days, then elects deferral on Form 8949 with a timely filed return and files Form 8997 every year the investment is held. On Form 8949 the client reports the sale, then a deferral line with the fund's EIN and investment date, showing the deferred amount as a negative adjustment⁶. Form 8997 reports QOF investments and deferred gain at the start and end of the year, gains deferred during the year, and dispositions⁵. The fund itself files Form 8996 to self-certify and report its 90% test⁷.

Form details are in Form 8996 and Form 8997, explained.

At the earlier of a sale or the fifth anniversary of the investment, the client includes the excess of the lesser of the deferred gain or the investment's fair market value over the client's basis in the investment¹. Basis starts at zero and rises by 10% of the deferred gain (30% for a Qualified Rural Opportunity Fund) after five years, so 90% or 70% is taxed if the investment has held its value⁸. CohnReznick's guide to mandatory inclusion walks through the formula and the fair market value limit¹⁶.

Illustration: a client invests a $400,000 gain in March 2027. In March 2032 the client includes $360,000 in a standard fund ($85,680 of tax at 23.8%) or $280,000 in a rural fund ($66,640). If the investment is worth only $300,000 at that date, inclusion is $300,000 less basis. Build estimated payments for the year that includes the fifth anniversary, since the fund interest itself is usually illiquid. See the five-year deferral and the basis step-up.

Two rules from Notice 2026-40 matter most for current clients¹⁰. First, gain still deferred from a QOF investment made on or before December 31, 2026 is included on that date, and that included gain is not eligible gain for a new deferral, because the original election remains in effect¹¹. Second, a gain realized in 2026 but invested in a QOF on or after January 1, 2027, inside its 180-day window, gets the five-year rolling deferral and the 10% or 30% step-up¹¹.

Notice 2026-55 asked for comments by November 23, 2026 on interim gains, inclusion events, working capital plan changes and the 30-year election¹². Expect further guidance. See key dates and timeline.

Fund clients must pass the 90% asset test on semiannual dates, keep their QOZBs within the 70%, 50%, 40% and 5% tests, and now meet new information reporting. A QOF that falls short of 90% owes a monthly penalty based on the shortfall and the underpayment rate, unless it shows reasonable cause¹. The law also added §6039K and §6039L reporting and a §6726 penalty⁸.

Proposed regulations published September 11, 2026 would make Form 8996 a separate information return, require census-tract-level data and create a single decertification procedure; they are not final⁹. See reporting requirements and penalties and the QOF 90% asset test.

Four situations account for most Opportunity Zone conversations: a large securities gain, the sale of a business, the sale of investment real estate, and a capital gain reported on a K-1. Each has its own timing and character issues, summarized below with links to the detailed guides.

In each case, confirm the client can hold for at least 10 years. The deferral and step-up are modest on their own; the exclusion of appreciation after 10 years drives most of the value, and it depends on the underlying investment performing.

State treatment can erase part of the benefit, so check the client's state of residence and the fund's states. California does not conform to the federal deferral or exclusion¹³. Other states are reported as non-conforming or partly conforming, and lists differ across sources, so verify each state for the year in question¹⁴. See state tax treatment of Opportunity Zone investments.

Advisers should also be ready to discuss sponsor quality and fees; see how to choose a sponsor. The final rules on Opportunity Zones remain T.D. 9889 and related regulations at 26 CFR 1.1400Z2, summarized by EY when issued³. Notice 2025-50 sets the rural definitions used for the 50% improvement rule¹⁷.
