Example 1.
(i) On May 1, 2004, when her IRA is worth $4,800, Taxpayer A makes a $1,600 regular contribution to her IRA. Taxpayer A requests that $400 of the May 1, 2004, contribution be returned to her pursuant to section 408(d)(4). Pursuant to this request, on February 1, 2005, when the IRA is worth $7,600, the IRA trustee distributes to Taxpayer A the $400 plus attributable net income. During this time, no other contributions have been made to the IRA and no distributions have been made.
(ii) The adjusted opening balance is $6,400 [$4,800 + $1,600] and the adjusted closing balance is $7,600. Thus, the net income attributable to the $400 May 1, 2004, contribution is $75 [$400 × ($7,600−$6,400) ÷ $6,400]. Therefore, the total to be distributed on February 1, 2005, pursuant to § 408(d)(4) is $475.
