Qualified Opportunity Zones for Business Owners: Deferring and Reducing Capital Gains
The Qualified Opportunity Zone (QOZ) program under IRC 1400Z-2 allows taxpayers to defer capital gains by reinvesting those gains into a Qualified Opportunity Fund (QOF) that invests in designated low-income communities. If the QOF investment is held for at least 10 years, the gain on the QOF investment itself is permanently excluded from income.
The two tax benefits:
-
Deferral of the original capital gain: The reinvested capital gain is deferred until the earlier of the date the QOF investment is sold or December 31, 2026 (the statutory deadline for the deferral). After 2026, the deferred gain must be recognized regardless of whether the QOF investment is sold. For amounts invested after December 31, 2026, new rules apply: the deferral runs until the earlier of the sale or 5 years after the investment.
-
Exclusion of gain on the QOF investment (10-year hold): If the QOF investment is held for at least 10 years, the gain on the QOF investment (the appreciation above the amount invested) is permanently excluded from income. The basis of the QOF investment is stepped up to fair market value at the time of sale after 10 years.
Practical impact for investments made before 2027: The deferral benefit is diminished because the deferred gain must be recognized by December 31, 2026. Amounts invested after that date get a rolling 5-year deferral instead. The remaining benefit is the 10-year exclusion on QOF appreciation, which is still significant for investments that appreciate meaningfully.
What qualifies as a capital gain for QOZ investment: Any capital gain (short-term or long-term) from any source: sale of stocks, sale of a business, sale of real estate, cryptocurrency gains. The gain must be reinvested in a QOF within 180 days of recognition. For partnership and S-Corp gains, the 180-day clock starts either from the entity’s sale date or from the last day of the entity’s tax year (the partner or shareholder can choose).
What’s a QOF, structurally: A corporation or partnership that holds at least 90% of its assets in Qualified Opportunity Zone property. QOZ property includes real estate, business assets, and businesses located in designated census tracts.
Basis step-ups: The original QOZ rules include a 10% basis step-up at the 5-year mark and an additional 5% at 7 years. Because the deferred gain is recognized by December 31, 2026, a new investment under those rules can’t reach either step-up, which leaves the 10-year exclusion as the primary benefit for current investments. For amounts invested after December 31, 2026, a 10% step-up at 5 years (30% for a qualified rural opportunity fund) applies.
How does the 10-year exclusion work?
What are the risks?
QOZ investments are real estate and business investments in designated low-income areas. The tax benefits don’t guarantee a good investment return. The QOF must meet substantial improvement requirements (for existing buildings, the QOF must invest an amount equal to the adjusted basis in improvements within 30 months) and 90% asset tests (90% of QOF assets must be QOZ property).
A QOF investment that declines in value provides no tax benefit (you can’t deduct the loss against the excluded gain, because there’s no gain to exclude). The investor should evaluate the underlying investment merits independently of the tax benefits.
How are long-term and short-term capital gains taxed differently?
Short-term capital gains (assets held one year or less) are taxed at ordinary income rates, which can be as high as 37%. Long-term capital gains (assets held more than one year) are taxed at preferential rates: 0%, 15%, or 20% depending on your taxable income. The 3.8% net investment income tax (NIIT) applies on top of both rates for taxpayers with modified AGI above $200,000 ($250,000 married filing jointly). The holding period is critical for tax planning: selling an asset one day before the one-year mark costs you the rate differential, which can be 20+ percentage points. Installment sales under IRC 453 can spread the recognition of gain over multiple years.

Which holding periods matter in an opportunity zone deal?
Several clocks run at once. Gain on the asset you sell is long-term only if you held it more than one year, and then it’s taxed for 2026 at 0%, 15% or 20% rather than at ordinary rates up to 37%. You then have 180 days from the sale to put the gain into a qualified opportunity fund, and a 10-year hold in the fund lets you take a fair market value basis when you sell.
- Under the current rules, deferred gain is included on the earlier of selling the fund interest or December 31, 2026, so a new investment can’t reach the old five and seven-year step-ups.
- For amounts invested after December 31, 2026, deferral runs five years from the investment, with a 10% basis step-up at five years (30% for a qualified rural opportunity fund).
- The 10-year exclusion carries into the new regime, with fair market value measured no later than 30 years after the investment.
