If You Reached Age 72 In 2021, You Might (Or Might Not) Have Until April 1, 2022 To Take Your 2021 RMD.

If you miss your RMD deadline, you owe the IRS an excise tax of 50% of your RMD shortfall. For example, if your RMD for 2021 is $10,000 and you withdrew only $5,000 by the deadline, you will owe the IRS an excise tax of $2,500 ($10,000-$5,000) x 50%.
