Distributions of excess contributions after due date for taxable year and certain excess rollover contributions
(A) In general In the case of any individual, if the aggregate contributions (other than rollover contributions) paid for any taxable year to an individual retirement account or for an individual retirement annuity do not exceed the dollar amount in effect under section 219(b)(1)(A), paragraph (1) shall not apply to the distribution of any such contribution to the extent that such contribution exceeds the amount allowable as a deduction under section 219 for the taxable year for which the contribution was paid— (i) if such distribution is received after the date described in paragraph (4), (ii) but only to the extent that no deduction has been allowed under section 219 with respect to such excess contribution. If employer contributions on behalf of the individual are paid for the taxable year to a simplified employee pension, the dollar limitation of the preceding sentence shall be increased by the lesser of the amount of such contributions or the dollar limitation in effect under section 415(c)(1)(A) for such taxable year.
(B) Excess rollover contributions attributable to erroneous information If— (i) the taxpayer reasonably relies on information supplied pursuant to subtitle F for determining the amount of a rollover contribution, but (ii) the information was erroneous, subparagraph (A) shall be applied by increasing the dollar limit set forth therein by that portion of the excess contribution which was attributable to such information.
For purposes of this paragraph, the amount allowable as a deduction under section 219 shall be computed without regard to section 219(g).
