Form 8801 is used to compute the minimum tax credit, if any, for alternative minimum tax incurred in tax years after 1986 but before 2010.
The amount on line 22 represents your regular tax liability for 2010, minus allowable tax credits. We calculate line 22 as:
Your regular 2010 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 16);
- education credit (from Form 8863, line 23);
- elderly credit (from Schedule R, line 22);
- adoption credit (from Form 8839, line 14);
- foreign tax credit (from Form 1116, copy 1, line 29);
minus: general business credit (from Form 3800, line 32).
We put the amount that results from this calculation on line 22 of Form 8801.
