The December 31, 2026 Opportunity Zone Inclusion: Measuring Investor Gain and Deciding Whether to Re-Defer

This hour is for investor-side tax counsel who already know the lesser-of formula. It works through the debt-inclusive hypothetical-sale measurement under Treas. Reg. §1.1400Z2(b)-1(e)(4) for partnership and S corporation QOF interests. That measurement often erases the benefit of a low valuation once the investor has taken debt-financed losses, distributions or liability reallocations. Attendees leave able to run the statutory and (e)(4) numbers side by side from the original Form 8949, Form 8997 and K-1 record, and to make and document an order-or-skip appraisal call. When the call is to order, they can scope a fund-interest valuation that will hold up. They can also sequence the 2026 return through character, NIIT, suspended losses, estimated tax and the state add-back reversal.

This hour covers the year-end decision for an investor still holding a pre-2027 QOF interest. The investor can hold through December 31, 2026, pay tax on the deemed inclusion, and keep the ten-year exclusion. Or the investor can trigger an inclusion event now and roll the recognized gain into a 2027 fund. The session works through the eligibility line Notice 2026-40 draws, the event-date and day-count arithmetic, and the trigger menu (sale, redemption, excess distribution, gift, §351 transfer). It then covers an anti-abuse risk ladder for which no guidance exists, the price of giving up the exclusion, and the taxpayer-identity and Form 8997 trail that carry the rollover. Attendees leave able to document a hold-or-trigger call made on incomplete facts, using a decision tree, a 180-day calendar, and a risk ladder.
