Opportunity Zones (created by the 2017 Tax Cuts and Jobs Act) let investors defer federal capital gains tax by reinvesting the gain into a Qualified Opportunity Fund (QOF) within 180 days. If the QOF investment is held 10+ years, all appreciation of the QOF investment itself is tax-free. As of 2026, the original 5-year (10% basis step-up) and 7-year (additional 5% step-up) benefits have expired — only deferral until 2027 plus the 10-year 0% on appreciation remain.
How Opportunity Zones Work in 2026
Sell an appreciated asset (stock, real estate, business). Within 180 days, reinvest the GAIN portion (not the entire proceeds) into a QOF. Defer federal tax on the original gain until December 31, 2026 (or when you sell the QOF investment, whichever is earlier). Hold the QOF investment for 10+ years, then sell. The original deferred gain is taxed at your then-current rate. ALL appreciation of the QOF investment itself is 100% tax-free if the 10-year hold is met.
What Expired vs What Remains
The original OZ program had three tiers of benefit: (1) Tax deferral until 2026, (2) 10% basis step-up at 5 years (must have invested by 2022), (3) Additional 5% step-up at 7 years (must have invested by 2019), (4) 0% tax on appreciation after 10 years. As of 2026, benefits 2 and 3 are no longer available — there's not enough time before the 2027 recognition date. Only tax deferral until 2027 and the 10-year tax-free appreciation remain available to new investors.
Risks and Practical Considerations
QOFs invest 90%+ of assets in Qualified Opportunity Zone Property — typically real estate developments in low-income census tracts. The illiquidity is severe: 10+ year hold, no secondary market, operator-controlled exit. Fees are high (1-2% management + 10-20% carry on profits). Many QOFs are structured around a single development project, concentrating risk. Investors should treat OZ investments as venture-style risk with deferred-tax upside — not as a bond-like tax shelter. See our 1031 exchange calculator for a more traditional deferral alternative.
