Actually the whole RMD thing is a great example of taking a sledge hammer to a problem that needs tweezers.
I get it you don't want people who have large balances to keep it in tax deferred accounts for various reasons.
What we got is one of the most complex set of rules in the whole field. Just look at how often there are questions about these rules.
Then after all that in the 20+ years I have done this I can't tell you how many <$100 RMD checks I have helped get issued. And I won't even talk very much about the number <$1 RMD checks I have seen. Compared to the RMD checks from say accounts with >$100,000 the numbers are a joke.
So much time, effort and cost to solve a problem that happens not very often.
They could repeal the law and I am convinced they wouldn't see much change in total tax revenue from the money kept in the plans.
