Qualified Opportunity Zones: IRC Section 1400Z CPA REG Guide

Master the qualified opportunity zone tax incentives under IRC Section 1400Z for the CPA REG exam. Covers capital gain deferral, basis step-up, and permanent exclusion of QOZ gains.

Qualified Opportunity Zone Tax Incentives

The Tax Cuts and Jobs Act of 2017 created the Qualified Opportunity Zone (QOZ) program under IRC Sections 1400Z-1 and 1400Z-2 to encourage long-term investment in economically distressed communities. The program offers three tiers of tax benefits for investors who reinvest capital gains into Qualified Opportunity Funds (QOFs): temporary deferral of the original gain, a partial step-up in basis on the deferred gain (for investments made before 2022), and permanent exclusion of gains from the QOF investment itself. CPA REG candidates should understand the mechanics of each benefit and the key requirements.

Deferral of Capital Gains

How Deferral Works

A taxpayer who realizes a capital gain from any source (sale of stock, real estate, business assets, etc.) can elect to defer that gain by investing an amount equal to the gain into a Qualified Opportunity Fund within 180 days of the sale. The deferred gain is recognized on the earlier of: the date the QOF investment is sold or exchanged, or December 31, 2026. This means all deferred gains will be recognized no later than the 2026 tax year.

The taxpayer does not need to invest the entire sales proceeds; only the gain amount must be reinvested to defer the gain in full. Any proceeds not reinvested are treated normally. The 180-day window begins on the date the gain would be recognized for tax purposes.

Election

The deferral election is made on Form 8949 (Sales and Other Dispositions of Capital Assets) by reporting the gain and the deferral. The taxpayer must also file Form 8997 annually to report the QOF investment status.

Basis Step-Up on Deferred Gains

Historical Incentives (Pre-2022 Investments)

For investments made in QOFs before January 1, 2022, the taxpayer's basis in the QOF investment was increased based on the holding period. If the QOF investment was held for at least five years, the basis was increased by 10% of the deferred gain. If held for at least seven years, an additional 5% step-up applied (total 15%). These step-ups reduced the amount of the deferred gain ultimately recognized.

Because the deferred gain must be recognized by December 31, 2026, the seven-year step-up is no longer available for any new investments (the last date to invest and achieve a seven-year hold before 2026 was in 2019). The five-year step-up was available for investments made by December 31, 2021.

Post-2021 Investments

For investments made on or after January 1, 2022, there is no basis step-up on the deferred gain. The taxpayer still receives deferral until 2026 and may qualify for the permanent exclusion on post-acquisition gains (discussed below), but the original deferred gain will be recognized in full in 2026.

Permanent Exclusion of QOF Gains

The 10-Year Hold

If a taxpayer holds the QOF investment for at least 10 years, any appreciation in the QOF investment itself (above and beyond the deferred gain) is permanently excluded from income. The taxpayer achieves this by electing to step up the basis of the QOF investment to its fair market value on the date of sale or exchange. This exclusion applies only to gains from the QOF investment, not to the original deferred gain.

For example, a taxpayer invests $100,000 of deferred gain into a QOF in 2021. By 2032, the QOF interest is worth $250,000. In 2026, the taxpayer recognizes the original $100,000 deferred gain (possibly reduced by the 10% step-up to $90,000 for investments held five years). When the taxpayer sells the QOF interest in 2032 for $250,000, the $150,000 of post-investment appreciation is permanently excluded from income.

Qualified Opportunity Funds

Requirements

A QOF is any investment vehicle organized as a corporation or partnership for the purpose of investing in qualified opportunity zone property. The QOF must hold at least 90% of its assets in qualified opportunity zone property, tested semi-annually. Qualified opportunity zone property includes: direct ownership of qualified opportunity zone business property (tangible property used in a trade or business in the zone), or ownership of stock or partnership interests in a qualified opportunity zone business.

Qualified Opportunity Zone Business

A business qualifies if substantially all (at least 70%) of its tangible property is qualified opportunity zone business property. At least 50% of the business's gross income must be derived from the active conduct of a business in the zone. Certain "sin businesses" (golf courses, country clubs, massage parlors, liquor stores, gambling facilities) are excluded.

CPA Exam Tips

  • Only capital gains (not ordinary income) can be deferred through QOF investments.
  • The 180-day investment window is measured from the gain recognition date.
  • All deferred gains are recognized by December 31, 2026, regardless of whether the QOF investment is sold.
  • The 10-year hold for permanent exclusion applies only to post-investment appreciation in the QOF interest.
  • The QOF must maintain 90% of its assets in qualified opportunity zone property.
  • Basis step-ups on deferred gains are no longer available for investments made after 2021.
