Life and Death Planning for Retirement Benefits
(2009) give any indication of the separate treatment of inherited IRAs or of the proper method of
reporting with respect to these accounts.
If the deceased participant had after-tax money in his IRA, the beneficiary takes over that
basis after the participant’s death. [This statement would appear to hold true even if the account is
worth less than the participant’s basis as of the date of death;
§ 1014(b)(applicable for deaths in
years before and after 2010), providing for an adjustment bringing basis to date-of-death value,
does not apply to “income in respect of a decedent” (IRD; see ¶ 4.6)
. § 1014(c) .For deaths
in
2010,
see
¶ 4.3.08 .]
Inherited IRAs are
not
aggregated with the beneficiary’s own IRA(s) for purposes of
determining how much of any distribution from either type constitutes tax-free return of basis. If
a beneficiary inherits IRAs from more than one decedent, he must track basis separately for the
IRAs he inherited from each decedent. The one exception to these statements applies to the
surviving spouse—if she elects to treat an IRA she has inherited from the deceased spouse as her
own IRA or rolls it over into her own IRA (se
e ¶ 3.2 ), the basis in the decedent’s IRA is just added
to hers. Inherited
traditional
IRAs are not aggregated with inherited
Roth
IRAs for any purpose.
See
¶ 5.2.03 (B).
2.2.08
How much of a traditional IRA distribution is basis?
Distributions from traditional IRAs are taxed under the cream-in-the-coffee rule of
§ 72 ( ¶ 2.2.02 ).
§ 408(d)(2) ; § 72(e)(2)(B) , (5)(A) , (5)(D)(iii) ,and
(8)(B) .For taxation of distributions
from a
Roth IRA
, see
¶ 5.2.03 .A special aggregation rule applies to IRAs that does not apply to other plans: For purposes
of determining how much of any particular distribution is a return of the participant’s basis, all of
the participant’s (noninherited) IRAs are treated as a single giant IRA (aggregation of accounts;
see “F” below) and all distributions during the year from the aggregated accounts are treated as
one single distribution (see “B”). Since the conversion of funds from a traditional to a Roth IRA
is treated as a distribution from the traditional IRA
( ¶ 5.4.03 ), these same aggregation rules are
used to determine how much income a participant realizes when he converts funds from a
traditional IRA to a Roth IRA. Reg.
§ 1.408A-4 ,A-7(a).
Here is the formula for determining how much of a particular year’s distributions from
(and Roth conversions of) traditional IRAs constitutes tax-free return of the participant’s
investment in the contract (basis), adapted from Notice 87-16, 1987-1 C.B. 446, Part III. The
taxable portion of traditional IRA distributions and of Roth conversions of traditional IRAs are
figured on different parts of IRS Form 8606 using this formula.
A.
The cream-in-the-coffee formula.
The total amount of the participant’s IRA distributions
for the year is multiplied by a fraction. The numerator of the fraction is participant’s total
basis in the aggregated accounts (“Nondeductible Contributions”). The denominator is the
[total balance of all his traditional IRAs as of the end of the year in which the distribution
occurs] plus [the Distribution Amount].
