Inherited spousal IRA reporting?

[Bruce S]

I am doing my mother's taxes for 2022.  My father passed late 2021.  In early 2022 we rolled my father's IRA into my mother's existing IRA at the same custodian.  Prior to rolling over, the custodian sent the required 2022 RMD from my father's IRA (I guess since there was a balance on December 31, 2021) to my mother, then rolled over the remaining balance.  We received a 1099-R for the amount of the RMD, with Code 4 Distribution due to death.  I know this is taxable.  My question is, should I have received any other reporting via 1099-R or other about the rollover amount?  Or am I good just reporting the RMD distribution from the 1099-R Code 4?

You are good just reporting the 1099-R for the RMD.  The transfer was obviously a direct rollover, so if they had issued you a 1099-R for the Rollover Distribution, it would be coded with a G for Direct rollover of a distribution to a qualified plan. When reported on a 1099-R, they need to be reported on your tax return, but it's a non-taxable event.

I'll assume that you have correctly identified your father's retirement account as being a traditional IRA and not an account like a 401(k) in an employer plan.

With no Form 1099-R for the movement of the funds to your mother's IRA, this was apparently appropriately done as nonreportable a trustee-to-trustee transfer (not a direct rollover; a trustee-to-trustee transfer of an IRA is neither a distribution nor a rollover).

Code G is never to be used to report the movement of funds from one IRA to another.

Just report the code-4 Form 1099-R.
