Such election shall be made in the form and manner prescribed by the Department and shall be made by the due date (including extensions of time) for filing the taxpayer's return for the taxable year in which such loss is incurred, and such election, once made, shall be irrevocable.(B) The entire amount of such loss shall be         carried to the earliest taxable year to which such loss may be carried.  The amount of such loss which shall be carried to each of the other taxable years shall be the excess, if any, of the amount of such loss over the sum of the deductions for carryback or carryover of such loss allowable for each of the prior taxable years to which such loss may be carried.(b) Any loss determined under subsection (a) of this Section must be carried  back or carried forward in the same manner for purposes of subsections (a)  and (b) of Section 201 of this Act as for purposes of subsections (c) and  (d) of Section 201 of this Act.(c) Notwithstanding any other provision of this Act, for each taxable year ending on or after December 31, 2008, for purposes of computing the loss for the taxable year under subsection (a) of this Section and the deduction taken into account for the taxable year for a net operating loss carryover under paragraphs (1), (2), and (3) of subsection (a) of this Section, the loss and net operating loss carryover shall be reduced in an amount equal to the reduction to the net operating loss and net operating loss carryover to the taxable year, respectively, required under Section 108(b)(2)(A) of the Internal Revenue Code, multiplied by a fraction, the numerator of which is the amount of discharge of indebtedness income that is excluded from gross income for the taxable year (but only if the taxable year ends on or after December 31, 2008) under Section 108(a) of the Internal Revenue Code and that would have been allocated and apportioned to this State under Article 3 of this Act but for that exclusion, and the denominator of which is the total amount of discharge of indebtedness income excluded from gross income under Section 108(a) of the Internal Revenue Code for the taxable year. The reduction required under this subsection (c) shall be made after the determination of Illinois net income for the taxable year in which the indebtedness is discharged.(d) In the case of a corporation (other than a Subchapter S corporation), no carryover deduction shall be allowed under this Section for any taxable year ending after December 31, 2010 and prior to December 31, 2012, and no carryover deduction shall exceed $100,000 for any taxable year ending on or after December 31, 2012 and prior to December 31, 2014 and for any taxable year ending on or after December 31, 2021 and prior to December 31, 2024; provided that, for purposes of determining the taxable years to which a net loss may be carried under subsection (a) of this Section, no taxable year for which a deduction is disallowed under this subsection, or for which the deduction would exceed $100,000 if not for this subsection,  shall be counted.(e)  In the case of a residual interest holder in a real estate mortgage investment conduit subject to Section 860E of the Internal Revenue Code, the net loss in subsection (a) shall be equal to:(1)  the amount computed under subsection (a),     without regard to this subsection (e), or if that amount is positive, zero;(2) minus an amount equal to the amount computed     under subsection (a), without regard to this subsection (e), minus the amount that would be computed under subsection (a) if the taxpayer's federal taxable income were computed without regard to Section 860E of the Internal Revenue Code and without regard to this subsection (e).The modification in this subsection (e) is exempt from the provisions of Section 250.
