does not prevent the application of this section to a total distribution even though the amount is received after the employee-participant ceases to be eligible for additional contributions and in a taxable year other than the taxable year in which the total amount is received.
For taxable years beginning after December 31, 1966, see section 72(m)(7) and paragraph (f) of § 1.72-17 for the meaning of disabled. For taxable years beginning before January 1, 1967, see section 213(g)(3) for the meaning of disabled. For taxable years beginning after December 31, 1968, if this section is applicable by reason of the distribution or payment being made after the employee has become disabled, then for the taxable year in which the amounts to which this section applies are distributed or paid, there shall be submitted with the recipient's income tax return a doctor's statement as to the nature and effect of the employee's impairment.
In any case in which the application of subdivision (ii) of this subparagraph results in an increase in taxable income for any taxable year, the resulting increase in taxes imposed by section 1 or 3 for such taxable year shall be reduced by the credit against tax provided by section 31 (tax withheld on wages), but shall not be reduced by any other credits against tax.
Example. B, a sole proprietor and a calendar-year basis taxpayer, established a qualified pension trust to which he made annual contributions for 10 years of 10 percent of his earned income. B withdrew his entire interest in the trust during 1973, for which year, without regard to the distribution, he had a net operating loss and is allowed under section 151 a deduction for one personal exemption. At the time of the withdrawal, B was 64 years old. The amount of the distribution that is includible in his gross income is $25,750. Because of B's net operating loss, the tax attributable to the distribution is determined under the rule of subparagraph (1)(ii) of this paragraph. For purposes of determining the tax attributable to the $25,750, B's taxable income for 1973 is treated, under subparagraph (1)(ii) of this paragraph, as being 20 percent of $25,000 ($25,750 minus $750, the amount of the deduction allowed for each personal exemption under section 151 for 1973). Thus, under subparagraph (1) of this paragraph, the tax attributable to the $25,750 would be 5 times the increase which would result if the taxable income of B for the taxable year he received such amount equaled $5,000. B has had no amounts withheld from wages and thus is not entitled to reduce the increase in taxes by the credit against tax provided in section 31 and may not reduce the increase in taxes by any other credits against tax.
