Certain contributions to employee stock ownership plans

Notwithstanding the provisions of paragraphs (3) and (7), if contributions are paid into a trust which forms a part of an employee stock ownership plan (as described in section 4975(e)(7)), and such contributions are, on or before the time prescribed in paragraph (6), applied by the plan to the repayment of the principal of a loan incurred for the purpose of acquiring qualifying employer securities (as described in section 4975(e)(8)), such contributions shall be deductible under this paragraph for the taxable year determined under paragraph (6). The amount deductible under this paragraph shall not, however, exceed 25 percent of the compensation otherwise paid or accrued during the taxable year to the employees under such employee stock ownership plan. Any amount paid into such trust in any taxable year in excess of the amount deductible under this paragraph shall be deductible in the succeeding taxable years in order of time to the extent of the difference between the amount paid and deductible in each such succeeding year and the maximum amount deductible for such year under the preceding sentence.
