710:50-15-53 Oklahoma net operating loss for individual returns
(a) Oklahoma net operating losses shall be separately determined by reference to Section 172 of the Internal Revenue Code and will be calculated utilizing Oklahoma Form 511-NOL Schedule A for resident individuals and Form 511-NR-NOL Schedule A for nonresident and part-year individuals. (b) An election may be made to forego the net operating loss (NOL) carryback period. In order to waive the carryback period, a written statement of the election must be part of the timely filed Oklahoma loss year return. (c) The years to which such losses may be carried shall be determined by reference to Section 172 of the Internal Revenue Code, as follows: (1) For NOLs incurred for tax years beginning on or after January 1, 2001, and ending on or before December 31, 2007, the loss carryback shall be for a period as allowed in the Internal Revenue Code; and (2) For NOLs incurred for tax years beginning after December 31, 2007, and ending on or before December 31, 2008, the loss carryback period shall be for a period of 2 years; and (3) For tax years beginning after December 31, 2008, the loss carryback period shall be for a period as allowed by Section 172 of the Internal Revenue Code. (d) Resident individuals will use Oklahoma Form 511-NOL Schedule B to compute the amount of the loss absorbed in each intervening year. Nonresident and part-year resident individuals will use Oklahoma Form 511-NR-NOL Schedule B to compute the amount of loss absorbed in each intervening year. (e) Taxpayers who incur a NOL from farming, allowed under IRC § 172 (b)(1)(B), in tax years beginning after December 31, 1999, will be allowed to carry that loss back, in accordance with the carryback provisions of the Internal Revenue Code. However, the amount of the farm NOL available for carryback is limited to the lesser of $60,000 or the loss shown on Federal Schedule F of the Internal Revenue Service Form 1040, reduced by 50% of the income from all other sources, except those included on Federal Schedule F.
