"RMD Basis Value of $50,104.07

Then lists assets with total FMV of $50,104.07"

If they match, then that is not what we've been discussing. It helps to know the word "basis" is used in many ways. All it means, really, is "based on."

"Trad IRA Basis" is the amount in a tax-deferred or sheltered account that was already taxed, or Post-tax, because it is not taxable again coming out, if it was taxed before going in. That would be, for instance, a Nondeductible contribution that someone made and then decided not to do a Backdoor Roth. And perhaps there is no Basis (already taxed funds) in this account at all. It can be unusual.

But the word Basis, applied to RMD, would mean: Here is the RMD value to use for the RMD table, to know you are taking an appropriate RMD. The deceased, if over 70 1/2 (now, at 72) would be taking Required Minimum Distributions as computation for the life expectancy table, that person's age, and their FMV of the account per the RMD rules.

Your client has a different rule than the life expectancy rule. Your client falls under the Inherited non-spousal rule and the SECURE Act applies: "Starting with those inherited after Jan. 1, 2020, the SECURE Act requires the entire balance of the participant's inherited IRA account to be distributed or withdrawn within 10 years of the death of the original owner."

Elsewhere on this forum, there is a recent topic for the question of taking it as RMD over 10 years, or holding off and taking it all at the end, or variations, is under scrutiny by the IRS, again. They are still trying to figure out how to comply with the SECURE Act changes.
