Business Use Accumulated ACE

If the business use has not been 100 percent throughout the life of the asset this box may be used to enter the net business use accumulated ACE depreciation. Do not include prior year Section 179 or ITC basis adjustment.

If the automatic sale feature is used with this asset, this entry will be used for the calculation of total ACE depreciation rather than the gross accumulated ACE depreciation amount entered.

This box is not valid for Form 1120S returns.
