In your case above you aren’t using the QCD to meet your RMD as you directly withdrew $25K (to yourself) and in addition you made a $60K QCD which doesn’t add to your AGI. So your ordinary income is still $100K
I suspect that’s causing some confusion.
If you had instead donated the $25K as a QCD which also met your RMD requirement, then your ordinary income would have been $75K.
That is what I meant to say.
I guess I figured that with $75,000 ordinary income and the need to do a $25,000 RMD I would have an AGI of $100,000. But doing the QCD (by having the broker send it to the charity) whether I did $25,000 or $60,000 QCD my AGI would be $75,000 at the end.
Thereby saving me from hitting some hypothetical cliff trigger at $100,000.
