c.
For taxable years beginning prior to January 1, 2013, if the taxpayer makes a valid election to
forego the carryback period as provided in Subsection 201.05, the provisions of Subsection 201.04.c. do not apply
and the net operating loss carryover is applied as follows:
(4-6-23)
i.
For net operating losses incurred in taxable years beginning on and after January 1, 2000, but prior
to January 1, 2013, the net operating loss is subtracted in the twenty (20) succeeding taxable years, in order, until the
loss is absorbed.
(4-6-23)
d.
For taxable years beginning prior to January 1, 2013, if the taxpayer fails to make a valid election to
forego the carryback period, the net operating loss must be carried back. If a carryback year is closed due to the
statute of limitations, the net operating loss carryback may not result in a refund for the closed taxable year. (4-6-23)
e.
For net operating losses incurred in taxable years beginning on and after January 1, 2013, if an
amended return carrying back the loss is filed within one (1) year of the end of the taxable year of the net operating
loss, the net operating loss is applied to the second preceding taxable year and if not absorbed, the difference is
applied to the first preceding taxable year. The loss not absorbed in the carryback years is subtracted in the twenty
(20) succeeding taxable years, in order, until absorbed.
(4-6-23)

a.
Net operating losses incurred in taxable years beginning on or after January 1, 2010. The election
must be made by the due date of the loss year return, including extensions. Once the completed return is filed, the
extension period expires. Unless otherwise provided in the Idaho return or in an Idaho form accompanying a return
for the taxable year, the election referred to in this Subsection may be made by attaching a statement to the taxpayer's
income tax return for the taxable year of the loss. The statement must contain the following information:
(4-6-23)
i.
The name, address, and taxpayer's social security number or employer identification number;
(4-6-23)
ii.
A statement that the taxpayer makes the election pursuant to Section 63-3022(c)(1), Idaho Code, to
forego the carryback provision; and
(4-6-23)
iii.
The amount of the net operating loss.
(4-6-23)
b.
Attaching a copy of the federal election to forego the federal net operating loss carryback to the
Idaho income tax return for the taxable year of the loss does not constitute an election for Idaho purposes.
(4-6-23)
c.
If the election is made on an amended or original return filed subsequent to the time allowed in
Paragraph 201.05.a, it is considered untimely.
(4-6-23)
06.
Order in Which Losses Are Applied in a Year. Loss carryovers are deducted before deducting
any loss carrybacks applicable to the same taxable year.
(4-6-23)
07.
Documentation Required When Claiming a Net Operating Loss Deduction. A taxpayer
claiming a net operating loss deduction for a taxable year must file with his return for that year a concise statement
setting forth the amount of the net operating loss deduction claimed and all material and pertinent facts, including a
detailed schedule showing the computation of the net operating loss and its carryback or carryover.
(4-6-23)
08.
Conversion of C Corporation to S Corporation. An S corporation may not carry over or back a
net operating loss from a taxable year in which the corporation was a C corporation. However, an S corporation
subject to Idaho tax on net recognized built-in gains or excess net passive income may deduct a net operating loss
carryover from a taxable year in which the corporation was a C corporation against its net recognized built-in gain
and excess net passive income.
