Certainly looks useful as an early retiree if I can no longer contribute to an HSA and need to pay for medical expenses beyond what is in the HSA. It is a route to getting some money out of a tIRA tax free. Admittedly not a lot. A couple could get out a max of $13, 100 across 2 years if I read it correctly by each transferring the max in separate years. With a 15% marginal tax rate, that saves $1, 965 in taxes and leaves space for other purposes, like the Roth pipeline.
Over 50 and the limit is raised $1000 each
