(a)

General rule

If for any taxable year beginning in the recognition period an S corporation has a net recognized built-in gain, there is hereby imposed a tax (computed under subsection (b)) on the income of such corporation for such taxable year.

(b)

Amount of tax

In general

The amount of the tax imposed by subsection (a) shall be computed by applying the highest rate of tax specified in section 11(b) to the net recognized built-in gain of the S corporation for the taxable year.

Notwithstanding section 1371(b)(1), any net operating loss carryforward arising in a taxable year for which the corporation was a C corporation shall be allowed for purposes of this section as a deduction against the net recognized built-in gain of the S corporation for the taxable year. For purposes of determining the amount of any such loss which may be carried to subsequent taxable years, the amount of the net recognized built-in gain shall be treated as taxable income. Rules similar to the rules of the preceding sentences of this paragraph shall apply in the case of a capital loss carryforward arising in a taxable year for which the corporation was a C corporation.
