In Part II, Maximum Tax Credit and Carryforward, the taxpayer uses information from the other parts of the form to calculate his or her refundable credits and to determine the amount of any MTC carryforward.
In Part III, Tax Computations Using Maximum Capital Gains Rates, a taxpayer who had capital gains in the previous year calculates the amount of tax to be entered on line 11 in the calculation of the amount of the previous year AMT liability that was due to exclusion items in Part I.
