63-3022. The additions and subtractions set forth in this section, and in sections 63-3022A through 63-3022U, Idaho Code, are to be applied to the extent allowed in computing Idaho taxable income:

(a) Add any state and local taxes, as defined in section 164 of the Internal Revenue Code that are measured by net income, or for which a credit is allowable under section 63-3029, Idaho Code, and paid or accrued during the taxable year adjusted for state or local tax refunds used in arriving at taxable income.

(b) Add the net operating loss deduction used in arriving at taxable income.

(c)(1) A net operating loss for any taxable year commencing on and after January 1, 2000, but before January 1, 2013, shall be a net operating loss carryback not to exceed a total of one hundred thousand dollars ($100,000) to the two (2) immediately preceding taxable years. At the election of the taxpayer, the two (2) year carryback may be forgone and the loss subtracted from income received in taxable years arising in the next twenty (20) years succeeding the taxable year in which the loss arises in order until exhausted.

(2) A net operating loss for any taxable year commencing on or after January 1, 2013, shall be a net operating loss carryback not to exceed a total of one hundred thousand dollars ($100,000) to the two (2) immediately preceding taxable years only if an amended return carrying the loss back is filed within one (1) year of the end of the taxable year of the net operating loss that results in such carryback.

(3) Any portion of the net operating loss not subtracted from income in the two (2) preceding years may be subtracted from income in the next twenty (20) years succeeding the taxable year in which the loss arises in order until exhausted. The sum of the deductions may not exceed the amount of the net operating loss deduction incurred. The carryback shall be limited to a total of fifty thousand dollars ($50,000) in the case of an individual filing as married filing separate in the year of the loss.

(4) Net operating losses incurred by a corporation during a year in which such corporation did not transact business in Idaho or was not included in a group of corporations combined under section 63-3027(22), Idaho Code, may not be subtracted. However, if at least one (1) corporation within a group of corporations combined under section 63-3027(22), Idaho Code, was transacting business in Idaho during the taxable year in which the loss was incurred, then the net operating loss may be subtracted. Net operating losses incurred by a person, other than a corporation, in activities not taxable by Idaho may not be subtracted.

The deduction is allowed only to the extent such income is included in taxable income.

(i) In the case of a corporation, including any corporation in a group of corporations combined under section 63-3027(22), Idaho Code, add any capital loss or passive loss deducted, which loss was incurred during any year in which such corporation did not transact business in Idaho. However, do not add any capital loss deducted if a corporation, including any corporation in a group of corporations combined under section 63-3027(22), Idaho Code, was transacting business in Idaho during the taxable year in which the loss was incurred.
