Dec. 31 is the last day to donate shares to charity by the end of year deadlines. It’s also the last day you can convert a Traditional IRA to a Roth IRA and have it count for the 2020 tax year. The last market day of the year is also normally the last day to request a Required Minimum Distribution. However, the CARES Act has waived all RMD requirements for 2020. Please note that Qualified Charitable Distributions (QCDs) from IRAs require additional time to process and as such should be requested at least a week in advance of the December 31st deadline.
