Publication 17
taxmap/pub17/p17-157.htm#en_us_publink1000174222This section briefly discusses an additional tax you may have to
pay.
The tax law gives special treatment to some kinds of income and allows special deductions and credits for some kinds of expenses. Taxpayers who benefit from this special treatment may have to pay at least a minimum amount of tax through an additional tax called
AMT.
You may have to pay the AMT if your taxable income for regular tax purposes, combined with certain adjustments and tax preference items, is more than a certain amount. See Form 6251, Alternative Minimum Tax —
Individuals.

- Addition of personal exemptions,
