Today, the IRS issued final regulations describing a simplified method of accounting for gain and loss on shares in money market funds (MMFs) that are affected by certain SEC regulations. These SEC regulations allow no more than minimal fluctuations in the MMF’s net asset value (NAV) per share. The final regulations allow a taxpayer’s gain or loss on shares in an MMF to be based on the change in the aggregate value of the taxpayer’s shares and on the net amount of the purchases and redemptions for both stable and floating-NAV MMFs, broadening the rules from the proposed regulations which only allowed the NAV method for floating-NAV MMFs. These regulations are issued under sections 446 and 6045 and relate to proposed regulations issued on July 28, 2014.
