If a non-spouse inherits an IRA and fails to take the RMDs each year, I understand there's a 50% penalty. And there's also a form 5329 to request a waiver. Anyone have experience with that form? Is "the tax code is so convoluted, and I'm not a CPA/etc so I didn't know these accounts had RMDs" i.e. ignorance, ever accepted?
I'm answering a question on my site regarding this issue, and if waiver isn't likely, then it's a matter of a bit of math -
- the 4 years' missed RMDs add to about 12% of the account, so a 6% extra hit.
or
- use 5 year rule to withdraw 100%, avoid penalty, but have a large tax bill where I'm guessing the withdrawal will put the OP into the 25/28% bracket, where the small withdrawals might just be 15%.
I'm leaning to suggest the former is the better plan. (But curious how forgiving the IRS is on the missed RMDs. One imagines, reporting of accounts should flag this the first year it's missed. Shouldn't the custodian/broker/bank have some responsibility here?)
