What do I enter for excess business loss alternative minimum tax (AMT) adjustments?

You will need to complete an AMT Form 461  using amounts adjusted for AMT. Enter the difference between the AMT and regular tax limitation on losses. If Line 16 of the AMT Form 461 is less than the amount on Line 16 of the regular tax Form 461, enter the difference as a negative amount.

Keep your AMT Form 461 for your records because you'll need to carry over the loss to a future year.
