Qualified Opportunity Zones (QOZs) are designated economically distressed areas where investors can receive significant federal tax incentives by investing capital gains into a Qualified Opportunity Fund (QOF) that deploys capital in those areas. If you have capital gains from any source, you can roll those gains into a QOF within 180 days of the triggering sale and defer paying tax on the original gain until 2026 or when you sell the QOZ investment, whichever comes first. More importantly, if you hold the QOZ investment for at least 10 years, any appreciation on the investment itself is completely excluded from federal tax — only the original deferred gain (taxed in 2026) is subject to capital gains tax. The program was created by the 2017 Tax Cuts and Jobs Act to encourage private investment in low-income communities, and over 8,700 communities across the U.S. and territories were designated as Opportunity Zones. QOZ investments are complex and often illiquid, so the tax benefits must be weighed carefully against the underlying investment quality and the lock-up period.
