The Schedule T is used to report a difference in basis between federal and Wisconsin when you either sell or dispose of an asset. Also, it is used to report the difference in basis if you claim depreciation or amortization on an asset. Some exceptions may apply.
Use the Schedule T to compute the difference in basis and include the addition or subtraction amount on your Wisconsin return.
Enter the additions in the Addition to Income section and subtractions in the Subtraction from Income section of the Wisconsin return.
If you need to use the Schedule T, you will need to print and mail your return. The Schedule T cannot be attached to the electronic return.
