In order to obtain the 10-year benefit, the basis step up to fair-market value after holding a qualifying QOF interest for at least 10 years, under the proposed regulations you must sell or exchange your interest in the QOF on or before Dec. 31, 2047, or the QOF must sell or exchange its interest in a QOZB in a transaction that produces capital gain on or before Dec. 31, 2047. The only part of the proposed regulations that taxpayers may not rely upon are those relating to the 10-year benefit. As a result, it is not clear precisely which types of sales or exchanges will enable a taxpayer to obtain the 10-year benefit other than a sale. For example, a tax-free transfer to a partnership technically is an exchange. However, we do not know if a taxpayer could transfer its qualifying QOF interest to a partnership after the taxpayer held that qualifying QOF interest for at least 10 years and get a step-up to fair-market value. We do know that as a general rule, a transfer of a qualifying QOF interest to an aggregator partnership is not an inclusion event that causes acceleration of the deferred gain but the IRS and Treasury have not explained how the inclusion event rules and the 10-year benefit rules work together. You will have to wait for further guidance from the IRS and Treasury to fully answer your question. You should discuss this issue with your accountants or legal advisors. As you know, the QOZ provisions of the Internal Revenue Code are very complicated and the complying with highly technical rules are key to obtaining the benefits.
