The spreading of income over four years, as allowed by subdivision (b), shall not apply unless the taxpayer receives similar treatment for federal income tax purposes.

For taxable years beginning on or after January 1, 1987, each of the following shall
apply:
(1)
The adjusted basis of any partner’s interest in a partnership or shareholder’s stock in an “S corporation” shall be determined as if all of the income to be taken into account ratably in the four taxable years referred to in subdivision (b) were included in gross income for the first of those taxable years.
(2)
If any interest in a partnership or stock in an “S corporation” is disposed of before the last taxable year in the spread period, all amounts which would be included in the gross income of the partner or shareholder for subsequent taxable years in the spread period under subdivision (b) and attributable to the interest or stock disposed of shall be included in gross income for the taxable year in which the disposition occurs. For purposes of the preceding sentence, the term “spread period” means the period consisting of the four taxable years referred to in
