#### (a) Tax imposed

In the case of—

(1) an individual retirement account (within the meaning of section 408(a)),

(2) an Archer MSA (within the meaning of section 220(d)),

(3) an individual retirement annuity (within the meaning of section 408(b)), a custodial account treated as an annuity contract under section 403(b)(7)(A) (relating to custodial accounts for regulated investment company stock),

The amount of such tax for any taxable year shall not exceed 6 percent of the value of the account or annuity (determined as of the close of the taxable year). In the case of an endowment contract described in section 408(b), the tax imposed by this section does not apply to any amount allocable to life, health, accident, or other insurance under such contract. The tax imposed by this subsection shall be paid by such individual.

#### (b) Excess contributions

For purposes of this section, in the case of individual retirement accounts or individual retirement annuities, the term "excess contributions" means the sum of—

(1) the excess (if any) of—

(A) the amount contributed for the taxable year to the accounts or for the annuities (other than a contribution to a Roth IRA or a rollover contribution described in section 402(c), 403(a)(4), 403(b)(8), 408(d)(3), or 457(e)(16)), over

(B) the amount allowable as a deduction under section 219 for such contributions, and

(2) the amount determined under this subsection for the preceding taxable year reduced by the sum of—

(A) the distributions out of the account for the taxable year which were included in the gross income of the payee under section 408(d)(1),

For purposes of this subsection, any contribution which is distributed from the individual retirement account or the individual retirement annuity in a distribution to which section 408(d)(4) applies shall be treated as an amount not contributed. For purposes of paragraphs (1)(B) and (2)(C), the amount allowable as a deduction under section 219 shall be computed without regard to section 219(g).
