Form 8801 is used to compute the minimum tax credit, if any, for alternative minimum tax incurred in tax years after 1986 but before 2007.
The amount on line 22 represents your regular tax liability for 2007, minus allowable tax credits. We calculate line 22 as:
Your regular 2007 tax liability (from Form 1040, line 44, excluding any amount from Form 4972);
- child care credit (from Form 2441, line 11);
- child tax credit (from Child Tax Credit Worksheet, line 13);
- education credit (from Form 8863, line 17);
- elderly credit (from Schedule R, line 24);
- adoption credit (from Form 8839, line 18);
- foreign tax credit (from Form 1116, copy 1, line 29);
minus: general business credit (from Form 3800, line 19).
We put the amount that results from this calculation on line 22 of Form 8801.
