Wisconsin Addition to Income - Federal Net Operating Loss Carryover

Wisconsin does not use the Federal calculations for a Net Operating Loss (NOL) carryforward. Therefore, to enter a Net Operating Loss Carryover, you must make two entries. 

1. You must enter an Addition to Income for the full amount you claimed as a Federal Net Operating Loss (NOL) on your Federal return.
2. You will then need to calculate the Wisconsin Net Operating Loss, if applicable, using Publication 120 and enter the calculated number as a Subtraction from Income.
