RMD

The earliest you can take your first Required Minimum Distribution (RMD) is January 1st of the year you reach age 73.

You and your spouse each need to calculate your RMDs separately. The RMD will be based on the fair market value of the account(s) as of December 31st of the prior year. You can withdraw the entire required amount from just one or any combination of your IRAs. However, for other types of retirement plans like 401(k)s, the RMD must be taken from that specific account.

Note that RMDs are not required for all investment accounts. RMDs are required from the following:

• Profit-sharing plans
• 401(k) plans
• 403(b) plans
• 457(b) plans
• Traditional IRAs
• SEPs
• SARSEPs
• SIMPLE IRAs
• Roth IRA beneficiaries

Congratulations on reaching such an important milestone! I hope this info is helpful. I'll stay tuned in case you have any follow-up questions.

I turned 72 this year too.  You  have to start taking the RMD when you turn 73 .  So January  2026 would be the earliest.  Although you can delay taking the first  year RMD until April 1 of the next year 2027.  But what I started doing is taking QCD Qualified Charity Distributions from my IRA.  That will reduce your balance but not be taxable.  You can do QCD when you are 70 1/2.  A QCD will also count for your RMD and not be taxable.
