There were benefits to investors and funds alike. If an investor's 180-day capital gain reinvestment clock was to run out between April 1, 2020 to Dec. 30, 2020, this notice allows them to defer their gain using the OZ program through Dec. 31, 2020. The QOF has been allowed a "free" reasonable cause exception usage through the same time horizon, which keeps the fund from recognizing a penalty for failure to meet the 90% standard. Any assets undergoing substantial improvement can omit the period between April 1, 2020 to Dec. 30, 2020, when calculating their 30-month investment period. The QOF is allowed up to 24 months to reinvest proceeds from a sale of property or return of capital without penalty. A QOZB can extend their 31 or 62-month working capital safe harbor by up to 24 months.
