A partner in a Qualified Opportunity Fund (QOF) who divests before the end of the 10-year holding period will have an inclusion event, which generally means that the partner will recognize gain equal to the amount realized from the divestment over his basis in the interest (which will have been increased by his 10% and 5% basis step-ups, if he has held the interest for at least five and seven years, respectively, and, if the divestment occurs after Dec. 31, 2026, the amount of his deferred gain).
