Three QOZ benefits: (1) Defer original gain tax until Dec 31, 2026 (or whenever you sell QOF, if earlier). (2) Receive 10–15% basis step-up if held 5–7 years before the Dec 2026 recognition date. (3) After holding 10+ years, fully step up QOF basis to fair market value at exit — eliminating all appreciation tax. Window to invest is 180 days from realizing original gain.

What is a Qualified Opportunity Zone (QOZ)?

A Qualified Opportunity Zone (QOZ) is a designated low-income census tract where investors can defer and reduce capital gains tax by reinvesting through a Qualified Opportunity Fund (QOF). Created by the Tax Cuts and Jobs Act of 2017, there are about 8,700 QOZs across the US. To qualify, you must roll a capital gain into a QOF within 180 days of realization. The QOF must invest at least 90% of its assets in QOZ property — typically real estate or operating businesses located in the zone.

QOZ benefits are three-fold: (1) immediate deferral of capital gains tax until Dec 31, 2026 (or until QOF sale, whichever comes first); (2) a 10% basis step-up if held 5 years before recognition (15% if held 7 years — only available if invested by 2019/2021); and (3) tax-free appreciation on the QOF investment itself if held for at least 10 years. The 10-year step-up to fair market value is the biggest long-term benefit.

How the deferral math works

Suppose you realize a $500,000 capital gain in 2026. At a 30% combined federal + state rate, you'd owe $150,000 tax immediately. Roll that $500,000 into a QOF within 180 days: the $150,000 tax bill is deferred until Dec 31, 2026 (or until you sell the QOF). If your QOF grows at 7%/year for 10 years, the $500,000 grows to about $984,000 — and the $484,000 of appreciation is fully tax-free if you hold for 10 years.

Compare to the taxable alternative: pay $150,000 tax now, invest the remaining $350,000 at 7%/year. After 10 years it grows to about $688,000 — but you owe another 20–24% capital gains tax on the $338,000 of new gains. Net after-tax: roughly $610,000 vs $984,000 in the QOF — a $374,000 advantage from the QOZ structure, before considering NPV.

Eligibility, deadlines and risks

To invest in a QOF, the gain must be a capital gain — long-term, short-term, or Section 1231 gain from sale of business assets. Ordinary income, depreciation recapture and gain from sale-leaseback are not eligible. You have 180 days from gain recognition to invest in a QOF (or from the last day of a pass-through entity's fiscal year for K-1 gains). The QOF must self-certify on Form 8996 and meet the 90% asset test every six months.

Risks: (1) the 2026 deferred tax bill is due regardless of QOF value; (2) QOF investments are illiquid for 10 years; (3) QOZ areas may not appreciate as expected; (4) Treasury could change rules. Always consult a CPA before investing — QOZ is one of the more complex tax shelters in the code.
