Everything I read about the SECURE ACT mentions how the stretch IRA is gone, but there is an exception for minor children. Does that mean children of the original account holder or all children, including grandchildren? It seems that also, the minor child does not have to take any money out until they are no longer a minor (in their state of residence), then the 10 years kicks in. Does this mean I can still leave my Roth IRA to my grandson and he can let it grow tax free until he is 28 and then take out all of the money out at once (and since it is a Roth, tax free)?
The exception for minors is limited to the child of the participant, so no exceptions for grandchildren. If you left a Roth to a grandchild, the 10 year rule would kick in immediately, so there are no annual RMDs and no taxes, and the grandchild would do best to hold the inherited Roth and not distribute it until the end of the 10 year period. Being a tax free Roth, the parents would not have to deal with kiddie taxes like they would if a minor grandchild inherited a traditional IRA.
