Adjusted Gain or Loss
To calculate your alternative minimum tax adjustment for gain or loss, we figure separately your net capital gain or loss for regular tax purposes, and your net capital gain or loss for alternative minimum tax purposes.

Net capital gain or loss for regular tax purposes is your gain or loss from the sale of assets held one year or less, plus your gain or loss from the sale of assets held more than one year. If this amount is a loss which is larger than $3,000 ($1,500 if married filing a separate return), we limit the loss to $3,000 (or $1,500, if applicable).

Net capital gain or loss for AMT purposes is gain or loss from the sale of assets held one year or less, plus your gain or loss from the sale of assets held more than one year, plus any AMT adjustments to these amounts you told us about. Then we apply the $3,000 or $1,500 loss limitation described in the previous paragraph.

Once we have the regular and AMT net capital gain or loss amounts, your AMT gain or loss adjustment is the AMT net capital gain or loss minus the regular net capital gain or loss.
