I am 52 yoa and the beneficiaries of the IRA are my kids who are 18 and 15. This is basically their inheretance. I am hoping that after I die they would only take the MRD, so that the IRA could continue to grow for them. Is it wise to pay the tax now and roll it into a ROTH IRA. If so should I do it in intervals-maybe $100k for five yrs. I have not paid taxes on the $500k.
