Schedule NOL-MOD, officially titled Current Year Net Operating Loss Modification Information, is an Indiana Department of Revenue form used to adjust, explain, and track how a taxpayer’s federal net operating loss (NOL) is modified for Indiana tax purposes. Indiana does not always follow federal tax rules exactly, so when a taxpayer has a current-year loss, excess business loss, separately stated loss, discharged debt, or a loss acquired from an estate, trust, or consolidated group, this schedule ensures the correct Indiana-specific calculation is made. Schedule NOL-MOD captures required federal modifications, separately stated losses that do not directly appear on the return, losses affected by discharged indebtedness, and NOLs that are transferred, removed, or terminated. The form acts as a bridge between federal loss rules and Indiana law, making sure losses are reduced, increased, allocated, or eliminated properly before being carried forward or deducted on Indiana tax returns such as IT-40, IT-41, IT-20, IT-20NP, or FIT-20.
How To File Schedule NOL-MOD
Schedule NOL-MOD is filed with your Indiana income tax return for the year in which the net operating loss or modification occurs. It is not filed by itself. The completed schedule must be attached to the applicable Indiana return and to related schedules such as IT-40NOL, IT-20NOL, or FIT-20NOL when required. If filing on paper, include Schedule NOL-MOD in the proper enclosure sequence shown on the form. If filing electronically, the information from this schedule must be entered into your tax software exactly as shown.

How To Complete Schedule NOL-MOD
Below is a clear explanation of every line and field on Schedule NOL-MOD, rewritten for clarity without copying the original wording.
Header Information
Loss Year Ending
Enter the month, day, and year the net operating loss year ended.
Name Of Taxpayer
Write the full legal name of the individual, estate, trust, or entity filing the schedule.
Federal Employer Identification Number Or SSN

Part 1 – Required Federal Modifications For Net Operating Losses
Complete this section if you have a negative Indiana adjusted gross income or if specific federal deductions or limitations affect your Indiana loss.
Lines 1 Through 5 – Modification Codes And Amounts
For each applicable modification, enter:
- The correct three-digit modification code
- The dollar amount related to that code
Each line represents a separate adjustment. Amounts are generally entered as positive numbers unless instructed otherwise by the code description. If you have more than five adjustments, attach an additional schedule and include the total on line 6.
Line 6 – Total Modifications
Add together the amounts from lines 1 through 5 and enter the total here.
If you are filing IT-40, IT-40PNR, or IT-41, skip line 7 and carry this amount to line 8.
Also enter this amount on Schedule IT-40NOL or IT-20NOL line 3, if applicable.
Line 7 – Indiana Apportionment Percentage
If filing IT-20, IT-20NP, or FIT-20, enter your Indiana apportionment percentage as shown on your return. If no percentage applies, use 100%.
Line 8 – Modified Loss Amount
Multiply line 6 by line 7 and enter the result. This amount adjusts your Indiana net operating loss but cannot reduce it below zero.
Part 2 – Separately Stated Net Operating Losses
This section applies when a loss does not directly appear on the return, such as excess business losses or losses from estate or trust terminations.
Line 9 – Type Of Loss Code And Amount
Enter the three-digit code identifying the type of loss and the loss amount as a negative number. If multiple loss types apply, calculate each separately.
Line 10 – Indiana Modifications To The Loss
Enter the applicable Indiana modification code tied to line 9 and the related amount. Enter this as a positive number if it offsets the loss.
Line 11 – Adjusted Loss Amount
Add lines 9 and 10 together.
For IT-40, IT-40PNR, or IT-41 filers, skip line 12 and carry this amount to line 13.
Line 12 – Apportionment Percentage
For IT-20, IT-20NP, or FIT-20 filers, enter the Indiana apportionment percentage used on the return.
Line 13 – Apportioned Loss
Multiply line 11 by line 12. This represents the Indiana current-year net operating loss to be reported on the appropriate NOL schedule.
Line 14 – Loss From Estate Or Trust Termination
Enter any net operating loss received from a terminating estate or trust as a negative number.
Also enter:
- The year the loss was incurred
- The FEIN of the estate or trust
Use additional lines or sheets if more than one loss year applies.
Line 15 – Loss Used In Current Year
Enter the portion of line 14 that was deducted in the current year as a negative number.
Line 16 – Remaining Loss
Subtract line 15 from line 14. Enter this amount on the applicable NOL schedule as the remaining carryforward loss.
