Roth IRA holders can commingle Contributory and Conversion Roth IRAs in a single Account. Recently I was advised that we may wish to require customers at least to maintain a separate account for any amount converted from a Traditional IRA to a Roth IRA in calendar year 1998, as IRS guidelines require a withdrawal from a 1998 conversion Roth IRA within the first 5 years to be reported on Form 1099-R with a "special letter code." I'm advised that all other withdrawals from Roth IRAs are reported on Form 1099-R with a different letter code. Thus, requiring a separate account for 1998 conversions may help comply with this requirement.
QUESTION: Are separate accounts in this situation necessary, or hasn't TTCA-98, by reason of ordering distributions, done away with the advisability of separate accounts for 1998.
