appropriate federal forms within 120 days of such change. If an audit has been
conducted, copies of the audit report should also be enclosed. Payment of any

Indiana Code (IC) 6-3-4-6 requires taxpayers to notify the department within
180 days of any modication made to a federal income tax return.
Under IC 6-8.1-9-1, a taxpayer has 180 days from the date of modication by
the Internal Revenue Service to le a claim for refund with the department. Any
overpayment resulting from modication of federal income tax liability must
be claimed within the latter of 3 years from the due date of the return, 3 years
from the date of payment, or within 180 days of notication of change by the
Internal Revenue Service.

If ling because of an IRC Section 172 deduction, eective Jan. 1, 2004, the loss
derived from Indiana must be calculated by applying the modications, in eect
for the year in which the loss was incurred, used in arriving at Indiana adjusted
gross income. e resulting Indiana net operating loss (NOL), adjusted for any
federal Section 172 modications, may be claimed toward reducing, before any
other state deductions, Indiana adjusted gross income. Use Schedule IT-20NOL
(revised 8-09 and aer) to determine the available amount you may deduct.
A preexisting NOL must also be recalculated using this methodology to apply
any remaining loss as a deduction for tax years ending aer Dec. 31, 2003. All
NOLs incurred aer this date, whether carried back or forward, must be calculated
using the revised IT-20NOL schedule.
e available Indiana NOL is subject to the same carryover provisions as
